Description
Technical field
The utility model is related to Injection Mold Design technical field, more particularly to a kind of to improve the mould of injecting products trapped gas
Lamps structure.
Background technology
In the prior art, the crucial profiled part of injection mold is cavity plate and punch-pin, the process being molded in injecting products
In, due to raw material itself, micro-molecular gas is usually contained in the plastics of melting, further, since mould itself is tied
During structure reason, mould matched moulds, it is understood that there may be the situation that exhaust has some setbacks, these can all make small molecule of being adulterated in injecting products
Product trapped gas is also resulted under gas, serious conditions, makes to remain bubble in injecting products, and then influences the quality of product.Therefore
Require careful consideration the trapped gas problem of product during mold design, starts with from mould structure and is reasonably improved, it is ensured that injection production
The quality of product.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art to improve the mould of injecting products trapped gas there is provided a kind of
Structure, the structure can be effectively improved the trapped gas problem of injecting products, so as to ensure the quality of injecting products.
In order to achieve the above object, the technical solution adopted in the utility model is：It is a kind of to improve the mould of injecting products trapped gas
Cavity plate and insert, cavity plate and insert are provided with lamps structure, including master mold panel, caster and male template, described caster
Face is contacted；Punch-pin and air discharge duct are provided with described male template, air discharge duct connection push rod is that activity connects between push rod and punch-pin
Connect, also have sprue groove and branch flow passage groove in male template, the end of sprue groove is provided with cold slug well.
Further, insert as described above is fixed by screws on cavity plate.
Further, insert screwing as described above aligns with air discharge duct.
Further, air discharge duct as described above and branch flow passage groove be on the same line.
Further, cavity plate as described above, insert, punch-pin and push rod end collectively form closure cavity.
Further, the end of branch flow passage groove as described above passes through cast gate connection closure cavity.
Further, the surface of cavity plate as described above, insert and punch-pin is minute surface.
Compared with prior art, the beneficial effects of the utility model are：The utility model is by insert and the organic knot of air discharge duct
Close, while opening up push rod and air discharge duct according to gate location, be minute surface by the Surface Machining of cavity plate, insert and punch-pin, so may be used
Effectively to discharge the gas produced in injection moulding process, improve the trapped gas problem of injection-molded item.

Embodiment
It is described in detail referring to the drawings with reference to embodiment, to enter to technical characteristic of the present utility model and advantage
Row deeper into annotation.
As Figure 1-3, the mould structure of a kind of improvement injecting products trapped gas of the present utility model, including master mold panel 1,
Cavity plate 14 and insert 7, cavity plate 14 and the contact of the face of insert 7 are provided with caster 2 and male template 3, described caster 2, is coordinated
Precision is high, it is ensured that the presentation quality of injecting products, insert 7 is fixed by screws on cavity plate 14,11 pairs of the screw and air discharge duct
Together；Punch-pin 13 and air discharge duct 11, the connection push rod 6 of air discharge duct 11, between push rod 6 and punch-pin 13 are provided with described male template 3
To be flexibly connected, push rod 6 is stripped in separation, male template 3 after injecting products shaping sprue groove 12 and affluent-dividing
Road groove 10, with branch flow passage groove 10 on the same line, the end of sprue groove 12 is provided with cold slug well 9 to air discharge duct 11, is used to
Store and also remain with condensate at condensate, sprue puller 4.It is empty that cavity plate 14, insert 7, punch-pin 13 and the end of push rod 6 collectively form closure
Chamber, the end of branch flow passage groove 10 is by the connection closure cavity of cast gate 5, and the wherein surface of cavity plate 14, insert 7 and punch-pin 13 is mirror
Face, reduces the residual volume of micro-molecular gas.
It is of the present utility model simple in construction, introduce insert 7 and design, in the case where ensureing the precision of part and cooperation, edge
Gap between block 7 and Die and mould plate can be with auxiliary exhaust.According to the shape of product 8, it can set about from the quantity of cast gate 5 and position
It is designed, in the present embodiment, product 8 is small and regular shape, is molded using a cast gate 5, matched is exhaust
The selection of the position of groove 11, cast gate 5 is corresponding with the position of air discharge duct 11, and push rod 6, push rod 6 are set between air discharge duct 11 and product 8
Gap between Die and mould plate can also auxiliary exhaust., can after the surface mirror-polishing processing of cavity plate 14, insert 7 and punch-pin 13
Its surface is noted on effectively to reduce small molecule, the further exhaust outlet effect for improving injecting products, so as to effectively change
The trapped gas problem of kind injecting products, obtains good injecting products.
Clear, complete description is carried out to the utility model by the technical scheme in above example, it is clear that described
Embodiment be the embodiment of the utility model part, rather than whole embodiment.Based on the implementation in the utility model
