Detailed description of the invention
The manufacture method of gypsum silica gel double stack mold of the present invention comprises the following steps:
Step one, prototype is located, and with appropriate water and land plaster mixing furnishing calcium plaster, with calcium plaster, prototype reverse side (reverse side is the one side having screw column, buckle, one side inwardly during namely product installation) is positioned on table top upward.During location, prototype will place level (screw column position looks upon horizon with favor), and wax will be wiped in advance in the position of prototype contact calcium plaster, prevents gypsum from prototype is glued bad.
Step 2, builds die joint, builds die joint by plank and nail along die parting line.Plank should rise and fall according to the height of die parting line and be sawn into block not of uniform size and fix together by nail, too high just adds the strong point below.Die joint level in die parting line, about 60-70 mm wide.Will consider the problem of depanning when building die joint, make flat or make inclination, vertical place of trying not, bevelling never allows to occur especially.Because have gap between the plank fixed and plank, so will check, with adhesive tape, the gap beyond distance prototype 30 millimeters is all sealed up.Mud to be spread, so there is a gap also to affect not quite under position within 30 millimeters etc.At the periphery bonding frame surrounding highly about 50 millimeters of ABS offset plate of 502 glue and 2 millimeters thick of distance prototype 60 millimeters.Only have the very high prototype of die joint just to need to build die joint with plank, if the very low thickness even not reaching plank of die joint, somatotype can be carried out with sculpture clay.Die joint is that can directly die joint glue being fixed on table top of plane just completes somatotype.
Step 3, do sprue, exhaust outlet, alignment of basic pattern post, external mold guide pile, it is specific as follows: if the sprue size of vacuum machine used or low-pressure injection machine is 24 millimeters, mould sprue just makes the semicircle shape that diameter is 24 millimeters, is that the hose of 24 millimeters is cut open just passable from centre with diameter.The ABS offset plate of sticky one piece of 1.5 millimeters thick between hose and prototype, ABS offset plate is made upper base 50 millimeters and to be gone to the bottom the shape (size of concrete size is determined by the size of prototype) of isosceles trapezoid of 100 height 30 millimeters.Going to the bottom of isosceles trapezoid ABS offset plate is bonding with prototype, and upper base is bonding with the front end of hose, and the rear end of hose is bonding with the ABS offset plate enclosing frame.Because the mould done according to new technology erects mould and pours into a mould, so sprue is generally be placed on lower, and exhaust outlet is placed on eminence, such smooth gas discharge, and product bubble is few.Exhaust outlet directly makes just passable of the ABS offset plate of 2 millimeters thick, offset plate is cut into rectangular, width 8 millimeter, length be just prototype to the distance of enclosing frame, cement just passable with 502 glue two.It is just passable that alignment of basic pattern post diameter is that the ABS glue rod of 5-8 millimeter is cut into 20 millimeter length, 3-5 stress point is selected to be stained with locating dowel according to the size of prototype, cement a bit and each locating dowel all will perpendicular to the horizontal plane of prototype, crooked situation cannot be had to occur, otherwise when die sinking, this locating dowel can not pulled out out and caused bonding place to come off.Cement rear sand paper or perching knife and alignment of basic pattern post is accomplished fillet topmost, conveniently stripped.External mold location hemisphere is exactly the spheroid that diameter is 25 millimeters is cut away half from center (hemisphere can by resin or ABS plate well in advance.If prototype is very large, also can direct table tennis cut away half use), get each orientation all around that 3-6 hemisphere is bonded at plank die joint because be location external mold, so position is outer, the central point probably at distance prototype 45 millimeters of places as hemisphere.
Step 4, the mud layer of paving reverse side mould, specific as follows: the sculpture clay thin slice of 5-8 millimeters thick is covered on prototype and plank die joint, sculpture clay is pressed gently is adjacent to prototype.Alignment of basic pattern post can not by mud entirety parcel, and should wear out mud layer, major part is exposed, but just one section of 5-8 millimeter is buried by mud layer below is also inadequate, can paste the mud of one deck 5-8 millimeter on 10 millimeters, alignment of basic pattern post periphery again.Gao Dian, cusp or baroque local sculpture clay should be suitable thicker, can first take the 5-8 millimeter mud of fritter that one deck is first wrapped in these positions, and then the overall mud covering bulk, the mud at this place just has 15 millimeter thick like this, and present mud thickness is exactly later silica gel thickness.Have back-off not out of position such as position, hole and the buckle of mould, mud does not need by compressing into inside very dark button bit, and the mud that light covers one deck 5-8 millimeter is outside just passable.Like this, the inside of this some holes position and buckle is just silica gel entirely, if there is gypsum to enter to rupture not out of mould.From prototype to the mud in 30 millimeters of these regions of medium line of plank die joint, comprise the mud in sprue and exhaust outlet periphery 25 millimeters of regions, all should do thicker, because the silica gel of these counterdies in the localities also separates with scalpel later, silica gel is too thin easily to be cut through.The mud of one deck 5-8 millimeters thick can be covered again in these places.Mud wants trimming after completing, and the center line cutter along the plank die joint of 60 mm wides cuts, and mud unnecessary for outside is cleaned out.Namely be mud within distance prototype 30 millimeters of lines, beyond 30 millimeters of lines or plank.External mold locates hemisphere outside 30 millimeters of lines, so can not be covered by mud.Cut the location that limit starts to do between internal mold and external mold, the cuboid blockage (with Mold Making) of several long high 20 millimeters of 10 mm wides 10 millimeters is namely made with mud, these blockages are placed on uniformly on the surface of mud layer, are as the criterion to ensure that gypsum external mold and silica gel internal mold matched moulds tightly can not misplace.Note, the outermost of mud layer, namely hit exactly 30 millimeters of lines this region to prototype from plank die joint, mud blockage will be put closeer, because these mud blockages also play a part to ensure can not misplace between two panels silica gel internal mold.Then use the gap between clay sculpture hilt mud floating, rugged place is smeared suitable, accomplishes flat smooth as far as possible.
Step 5, makes the external mold of reverse side mould, specific as follows: alignment of basic pattern post is exposed at part, the plank die joint outside mud, and external mold location hemisphere coats coating of wax all uniformly; First adjust a small amount of calcium plaster, to comprise at mud layer and plank die joint with hairbrush and enclose frame and be coated with last layer all uniformly; After five minutes, gypsum pulp layer have cured.Adjust a little slightly rare calcium plaster in right amount again, both hands are held and are torn loose flax silk and immerse calcium plaster, more average for the flax silk that soaked with calcium plaster is spread out on mud layer more, as far as possible by real not below have space; Mud layer, the plank part also having die joint to be exposed all want uniform layer overlay flax silk calcium plaster, by paving, will not have space, and spread more smooth as far as possible when paving; The thickness of one deck flax silk calcium plaster is greatly about 15 millimeter, and the thickness of gypsum external mold should in 30 millimeter, so also will repave one deck flax silk calcium plaster; Two-layer flax silk calcium plaster has spread, and just can strengthen.If prototype is planar structure, anyhow respectively put several with square wood strip, batten staggered place flax silk calcium plaster wraps up, together with batten is taken off firmly with gypsum external mold.If prototype is housing or circular arc, preferably holds with the screw-thread steel of 4 millimeters or 6 millimeters the shape bending to gypsum external mold, anyhow respectively put several, then with flax silk calcium plaster, reinforcing bar is fixed up firmly.
Step 6, the mud layer of paving front mould, specific as follows: after the flax silk calcium plaster of reinforced steel have cured completely, just prototype to be turned together with gypsum external mold, start the gypsum external mold doing front.First plank die joint is removed, the gypsum of locating prototype at the beginning is also cleaned out, the frame that encloses of reverse side gypsum external mold is removed, check that whether the surface of the gypsum die joint of reverse side external mold is smooth, be uneven or the place of breakage if had, adjust calcium plaster to repair and polish.Until gypsum die joint looks very smooth-going, more again fencing up enclosing frame, still exceeding 50 millimeters above.The rubber materials in the tube mouth of that half be bonded at last time in prototype is taken off, changes the hose of the complete circle of a same length.Trapezoidal ABS offset plate does not then need to move.The mud thin slice of the sculpture clay of 5-8 millimeters thick is covered on prototype and die joint, and sculpture clay is pressed gently is adjacent to prototype.Gao Dian, cusp or baroque local mud layer still should be suitable thicker, can first take the 5-8 millimeter mud of fritter that one deck is first wrapped in these positions, and then the overall mud covering bulk, the mud at this place just has 15 millimeter thick like this, and present mud thickness is exactly later silica gel thickness.Have back-off not out of position such as position, hole and the buckle of mould, mud does not need by compressing into inside very dark button bit, and the mud that light covers one deck 5-8 millimeter is outside just passable.Like this, the inside of this some holes position and buckle is just silica gel entirely, if there is gypsum to enter to rupture not out of mould.From prototype to the mud in 30 millimeters of these regions of medium line of plank die joint, comprise the mud in sprue and exhaust outlet periphery 25 millimeters of regions, still should be thicker, the mud of one deck 5-8 millimeters thick can be covered again in these places.Mud complete after trimming, the center line cutter along the plank die joint of 60 mm wides cuts, and mud unnecessary for outside is cleaned out.Namely be mud within distance prototype 30 millimeters of lines, beyond 30 millimeters of lines or the gypsic horizon of reverse side external mold.The mud layer of reverse side mould is not destroyed when noting trimming.External mold location hemisphere at this moment can take out, just there is the groove of a semicircle after taking out, groove outside 30 millimeters of lines, so can not be covered by mud.Cut the location that limit starts to do between internal mold and external mold, or the cuboid blockage (with Mold Making) of several long high 20 millimeters of 10 mm wides 10 millimeters is made with mud, these blockages are placed on uniformly on the surface of mud layer, are as the criterion to ensure that gypsum external mold and silica gel internal mold matched moulds tightly can not misplace.Gypsum die joint 30 millimeters of center lines still will put some location blockages more to this region of prototype.Then use the gap between clay sculpture hilt mud floating, rugged place is smeared suitable, accomplishes flat smooth as far as possible.
Step 7, make the external mold of front mould, specific as follows: the gypsum part that reverse side external mold is exposed all is wiped twice wax uniformly, wax can be wiped a little more, prevents mould from not opening.First adjust a small amount of calcium plaster, to comprise at mud layer and gypsum die joint with hairbrush and enclose frame and be coated with last layer all uniformly; After five minutes, gypsum pulp layer have cured.Adjust a little slightly rare calcium plaster in right amount again, both hands are held and are torn loose flax silk and immerse calcium plaster, more average for the flax silk that soaked with calcium plaster is spread out on mud layer more, as far as possible by real not below have space.Mud layer, gypsum die joint enclose frame in addition and all want uniform layer overlay flax silk calcium plaster, inside the groove of attention location hemisphere, paving is empty, too many calcium plaster can not be had, calcium plaster must be soaked into flax silk to fill, otherwise it is not firm to locate hemisphere after carrying out with rear mold, is easy to come off.The thickness of one deck flax silk calcium plaster is greatly about 15 millimeter, and the thickness of gypsum external mold should in 30 millimeter, so also will repave one deck flax silk calcium plaster.Two-layer flax silk calcium plaster has spread, and can strengthen.If prototype is planar structure, anyhow respectively put several with square wood strip, batten staggered place flax silk calcium plaster wraps up, together with batten is taken off firmly with gypsum external mold.If prototype is housing or circular arc, preferably bends to the shape of gypsum external mold with the screw-thread steel of 4 millimeters or 6 millimeters, anyhow respectively put several, then with flax silk calcium plaster, reinforcing bar is fixed up firmly.
Step 8, bores screw hole, after the flax silk calcium plaster of reinforced steel have cured completely, remove enclosing frame, the drill bit that adept electric drill is first-class 16.5 millimeters, plays the perforation of ten (according to mould size and complexity, screw hole quantity can suitably increase and decrease) left and right at die joint exterior mold portion periphery.Note position, hole not too by inner, do not get to silica gel, can not be too outer, preferably beat the center at gypsum die joint.
Step 9, draws mud, specific as follows: the gap of inserting two halves gypsum external mold with perching knife, then with hammer knocking gently, just there will be crack between mold halves.Again mould is fallen excessively to knock below, when also occurring that dark a bit firmly sled to both sides is inserted perching knife again in crack below, two exterior mold halves just can open.Mould is all cleaned out the mud of tow sides mould, prototype is taken out and cleans with water after separating.Alignment of basic pattern post will be lifted down together when getting prototype, must not fall, when having fallen matched moulds again, prototype will depart from original position.After alignment of basic pattern post withdraws, gypsum external mold can leave several position, hole of not wearing, these positions, hole are also very important, do not have damage.Charging aperture and exhaust outlet have fallen not to be afraid of, is more again stained with just passable when matched moulds.Rear the gas of prototype cleaning blows clean water, pastes one enclose adhesive tape (parting, it is all such parting that Silicon moulds does in a lot of mould factory, and the time standby scalpel of die sinking cuts open along gelatin band steathily along die parting line.Such otch neatly can not hurt prototype again).Adhesive tape should not be too wide, stretches out the six or seven millimeter of prototype just passable.Color is coated with oiliness coloured pencil along adhesive tape outer rim again after adhesive tape posts.Charging aperture and steam vent also coat color along center line.A releasing agent is all sprayed in the region of two halves plaster mold just having been dug out mud, and the tow sides of prototype are also all sprayed a releasing agent.Prototype is put into reverse side external mold, allows each root locating dowel enter respectively inside corresponding position, hole, ensure that prototype does not have off normal.Charging aperture and steam vent are cemented again solid, the outermost end of charging aperture and steam vent, because the support without mud becomes unsettled, can be got two fritter silica gel, be whittled into the thickness pad of mud layer below.Charging aperture and steam vent are respectively bored two apertures, with pin, charging aperture and steam vent is fixed on silica gel, charging aperture and steam vent will in the centre positions of two-half die, not off normal.Reexamine the position of prototype, after confirming do not have off normal, a wax is wiped in the place contacted in the position, hole of alignment of basic pattern post and gypsum external mold, and then each point glue.Glue is unsuitable too many, fixes prototype and can not rock just passable.Front external mold is covered, screw is put into screw hole, nut of screwing on, locking.
Step 10, fill with silica gel, draw the ABS offset plate of four piece of 2 millimeters thick, the frame of high 100 millimeters long 100 mm wide 50 millimeters that fences up at charging aperture periphery with 502 glue and PUR, because silica gel fills with from charging aperture, this frame has the effect of funnel when filling with silica gel.Calculate and need how much silica gel, fall required silica gel (the translucent silica gel of the most handy slow curing of silica gel) in a reservoir, add curing agent and stir, vacuumize, then from the charging aperture of mould, silica gel is filled with.When exhaust outlet has silica gel to overflow, illustrate that the silica gel in die cavity is full.
Step 11, die sinking, specific as follows: after silica gel solidifies completely, unscrew nut, take out screw, with perching knife, mould is pried open.After two exterior mold halves is taken away, silica gel to be still wrapped in prototype.To draw into from the medium line of charging aperture with scalpel that (silica gel outermost end should cut into zigzag, the effect of location can be played), draw the adhesive tape of the inside, then the color that follow coloured pencil to stroke, until whole two panels Silicon moulds is all separated, prototype is taken out.The silica gel internal mold of reverse side is put into external mold, at this moment can see the position, several hole that alignment of basic pattern post stays.The ABS glue rod cutting several thickness length same with alignment of basic pattern post is put into inside position, hole, notices that glue rod higher than silica gel, can not be put down with silica gel face or can slightly lower than silica gel face (when producing later, often make a product these several ABS glue rods and all will wipe once).
Points for attention of the present invention are as follows: when one, producing, gypsum external mold will be handled with care, can not fall, and can not strike by direct hammer, and the place easily touching material often produces a mould and all will wipe wax or release agent spraying.Two, closing method.First reverse side internal mold should be put into reverse side external mold during matched moulds, allow those several glue rods replacing alignment of basic pattern post enter the position, hole of silica gel internal mold.Silica gel internal mold by pasting, guarantee that each location blockage is incorporated into position.Next front silica gel internal mold is closed, the laciniation of attention periphery all will close sternly does not have off normal.Finally front external mold is covered, checking to have does not have local top to arrive, if there is blockage top, location to arrive, just the place knife pushed up is cut away again.Matched moulds completes locking of just tightening up a screw, and starts to pour into a mould product.Three, as fruit product has local to have bubble, only need to pierce through an aperture at the silica gel internal mold place that these structure outermost end are corresponding gently with 1 millimeter of vent needle, just gas can be released, reduce the generation of bubble.If four need second time to make mould, also as saying in above operation, prototype is taped, prototype and gypsum external mold release agent spraying, then put gypsum external mold into prototype, and it is just passable that matched moulds tighten the screws fills with silica gel.If five product quantities reach hundreds of more than, delivery date is very tight again, needs ... number of molds is many, at the very start can make a few cover gypsum external mold more.After namely gypsum external mold is carried out, mould is opened and does not first fill with silica gel, such as prototype and mud layer have all been bonded at reverse side external mold, just the gypsum die joint of reverse side are wiped wax at once, then make the gypsum external mold in half front.When the quantity of front gypsum external mold is much of that, prototype is put into front external mold, starts the gypsum external mold doing reverse side.The external mold quantity on two sides is much of that, and another closes mould to fill with silica gel.Order volume is more in a word, and new technology advantage compared with traditional handicraft is more obvious.
The material that the present invention uses is as follows: mould gypsum powder, plank, nail, adhesive tape, 502 glue, ABS offset plate, ABS offset plate, diameter are that ABS glue rod, cutter, clay sculpture cutter, hairbrush, flax silk, batten, diameter 6 millimeters of screw-thread steels, electric hand drill, drill bit, the diameter of 5 millimeters is 16.0 millimeters and screw, scalpel, demoulding wax, canned releasing agent, the sculpture clay thin slice of length 100 millimeters.
According to the mould that method provided by the invention makes, the silica gel amount conservative estimation that same prototype uses is 1/3rd of traditional silicon sealing rubber die.Silica gel about 30 yuan per kilograms, land plaster about 1.5 yuan per kilograms, hundreds of family of palm factory and fast mould factory in the whole nation, if new technology can be promoted the use of, the annual silica gel saved in the whole nation is just worth tens million of unit.Silica gel is high energy-consuming industry, and in promotion energy-conserving and environment-protective instantly, this new technology of develop and spread is the good thing of benefiting the nation and the people.The external mold of plaster mold is crisp hard gypsum, is tightly wrapped in internal mold and prevents distortion.The internal mold of plaster mold is the layer of silica gel of 5-8 millimeter, first external mold is taken away, and de-internal mold is simple just as undressing.The inconvenient demoulding of traditional silica gel mould, adds too complicated position releasing agent and sprays not in place, cause only having about 20 times die life.And new technology overcomes these defects, reach 30 five to four ten die life.The pliable and tough easy demoulding of silica gel and the firm indeformable of gypsum combine by the present invention, and successfully the time shorten making mould to and do Silicon moulds length about the same.Thus saved most silica gel, alleviate the burden of enterprise.In addition, although the speed that new technology provided by the invention (hereinafter referred to as new technology) first time makees mould is slightly slower than traditional Silicon moulds technology, but the gypsum external mold of new technology can recycle, more than 30 covers, the product at least doing twice silica gel mould is needed for order volume, still compares and have superiority doing new technology in the speed of mould.General silica gel mould is produced and is just started sticking to mould more than 20 time, at this moment just need again to make mould, that is traditional handicraft is often made a mould and all will be started from the very beginning, as long as and new technology second time third time makees mould time prototype is put into external mold to close mould just passable to fill with silica gel.For five or six ten even up to a hundred product needed do three times with the order of mold, new technology in the speed making mould even slightly faster than traditional Silicon moulds technique.The present invention's gypsum instead of a large amount of silica gel, has saved cost, is exactly in addition to accelerate the time making mould, just can Mold Making is good within one day.
Sculpture clay thin slice is not greasy filth, and that mud of mud carving does in a lot of exactly sculpture factories.Dig the natural clay come from the ground to add water and make, than greasy filth considerably cheaper, more handy than greasy filth again.Greasy filth will be baked, sculpture clay become dry directly add water rub several under can use again.If need the sculpture clay thin slice of 5 millimeters thick, cut the ABS offset plate of two thick 5.0 mm wide 25 millimeters long 500 millimeters.Parallel for these 300 millimeters, two offset plate intervals is bonded on table top with glue, table top sprays a releasing agent.Then the sculpture clay of bulk is placed in the middle of two offset plates, first sculpture clay is pressed to flat with hand as far as possible, take the ABS glue rod of a diameter 30 millimeters of thicknesses again, with the offset plate on both sides for benchmark, firmly roll pressure sculpture clay, until the sculpture clay of centre is rolled the same with the offset plate on both sides thick, the sculpture clay thin slice of 5 millimeters thick has just been made.21, the location mud blockage way between interior external mold.First take the gypsum perching knife of fritter to be whittled into required size, then with sand paper, each is ground smooth, corner angle are polished rounder and more smooth.Blockage is preferably one large one small, has some pattern drafts with conveniently stripped.Such blockage is 30-50, is then several rows ofly upside down bonded at large for the blockage of these gypsum on table top with glue, each 15 millimeter in interval all around.Draw four piece of 1.5 thick ABS offset plate around blockage, impale a high frame of 30 millimeters.Adjust a small amount of silica gel, with small brushes on gypsum blockage, on table top and enclose frame inwall and smear one deck silica gel all equably.Have cured in silica gel adjusts proper silica gel to smear one time more again.The calcium plaster that after twice silica gel parches, tune half barrel is rare fills and encloses frame, and calcium plaster completely solidification goes 4 to fall to enclose frame later, monoblock gypsum is turned, takes away gypsum external mold, takes out the gypsum blockage inside Silicon moulds.Even if carried out to mould here.When producing, silica gel internal mold is put into gypsum external mold, slightly soft sculpture clay firmly by compressing in the groove of blockage one by one, first gypsum external mold is taken away after all completing, the layer of silica gel of the inside is just easy to the demoulding.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, present invention covers the various remodeling in the scope falling into appending claims and equivalent thereof and change.
