Description
Technical Field
The invention relates to a vacuum forming die for an integral refrigerator liner, in particular to a main body translation mechanism for the vacuum forming die for the integral refrigerator liner, and belongs to the technical field of vacuum (adsorption) forming dies.
Background
The refrigerator can be divided into two doors, three doors, four doors, multiple doors, opposite doors and the like according to the door structure, each door is internally provided with independent and airtight areas formed by different inner containers, foaming materials are filled between the areas, the heat insulation and heat preservation effects are achieved, and the temperature in each area can be different for storing different food materials. Considering manufacturability during adsorption molding of plates, most refrigerator products are designed into an independent part for each refrigerator liner, and different liners are connected together through different cross beams and vertical beams and then foamed to generate a foamed box body.
In the aspect of reducing the cost of products, some domestic household appliance enterprises have tried to design the inner containers of the refrigeration and freezing boxes into one connected part, so that a connecting beam between the inner containers of the refrigeration and freezing boxes is omitted, and as the distance between the two inner cavities is smaller, about 70 mm, when an adsorption mold is used for forming, the stretching ratio of a plate between the two inner cavities is too large, the thickness of the plate between the two inner cavities is very thin and less than 0.6 mm (the thinnest part of the inner container of the refrigerator is required to be more than or equal to 0.6 mm), even the plate is often pulled apart, the product is scrapped, and under the condition of increasing the thickness of the formed plate, the thickness difference of the product is too large, the effect is not good, and finally the plate is changed into the previous two parts. The adsorption molding die is a die with two cavities (refrigeration and freezing), but when the die is designed, the distance between the two die cavities can be increased, the stretching ratio of a plate between the two die cavities during molding is reduced, and molding is facilitated.
At present, part of domestic refrigerator enterprises export products to developed countries such as Europe and America, and one type of products is: the refrigerator with large refrigeration and small refrigeration has the purchasing requirements of being a combined inner container for refrigeration and refrigeration at foreign countries, and the split type refrigerator is not allowed. The refrigerator has the characteristics that 1. The refrigerator has small freezing and general height of less than or equal to 400 mm and depth of about 500 mm; 2. the distance between the refrigerating and the freezing is small, and the distance between the two containers is not less than 40 and not more than 70 mm.
Aiming at the refrigerator products of the type, the vacuum forming die at home and abroad has the following defects:
1. The domestic vacuum forming die does not have a good method for solving the problem of large material stretching ratio between the refrigerating and freezing inner containers, and the main method is to increase the thickness of the formed plate to ensure that the thinnest thickness of the inner container is more than or equal to 0.6 mm. The current formed plate has the thinnest thickness of 5mm, and the qualification rate is only about 80 percent.
2. The European and American die enterprises improve the product qualification rate by controlling different temperatures of the refrigerating and freezing die cavities during the adsorption molding, so that each adsorption molding device needs more than two die temperature machines to ensure that the current minimum thickness of the molded plate is 4.5 mm, and the qualification rate is only about 95%.
3. Aiming at two points and the last three years, a vacuum forming die for a refrigerator liner with a main body mechanism capable of swinging is developed in China, the thickness of a formed plate is 4.0 millimeters at the present, and the qualification rate is about 99 percent.
However, the third swingable main body mechanism related art can only be used for freezing main bodies at present, the main body appearance is relatively simple, and relatively complex freezing inner containers such as a sliding block mechanism, a large core pulling mechanism and the like cannot be provided, and the main reasons are that the relatively complex freezing inner container mechanisms are more, the whole weight is heavy, the inertia is large, and if the swinging mechanism is used, the reliability of the mechanism is poor, so that the mass production cannot be satisfied.
Therefore, how to develop a vacuum forming die capable of improving the product qualification rate of the conjoined vacuum forming and reducing the thickness of the formed plate, and meeting the requirement of vacuum forming of conjoined inner containers with various shapes, has become a technical problem which needs to be solved urgently.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides the main body translation mechanism for the vacuum forming die of the conjoined refrigerator liner, which can not only improve the qualification rate of conjoined vacuum forming products and reduce the thickness of formed plates, but also be suitable for vacuum forming of conjoined liners of various shapes.
The technical scheme adopted for solving the technical problems is as follows: the vacuum forming die for the inner container of the conjoined refrigerator mainly comprises a refrigerating mechanism, a freezing mechanism, a base and a bottom plate, wherein the bottom plate is fixedly connected below the base, the refrigerating mechanism is fixedly connected to one side above the base, the freezing mechanism is in sliding connection with the base on the other side, fixed copper bars are fixedly connected to the periphery of the refrigerating mechanism and the base on the periphery of the inner side of the freezing mechanism, a lifting copper bar is arranged on one side of the outer side of the freezing mechanism, and a gap of 0.5 mm is reserved between the side surface of a main freezing body and the fixed copper bar; the main body translation mechanism comprises a horizontal movement assembly arranged between the freezing mechanism and the refrigerating mechanism and a lifting assembly arranged between the lifting copper bar and the base, the freezing mechanism automatically translates along the direction far away from or near the refrigerating mechanism through the horizontal movement assembly respectively, and in the translation process, the lifting copper bar automatically slides up and down under the action of the lifting assembly.
Compared with the existing vacuum forming die, the main body translation mechanism for the vacuum forming die of the conjoined refrigerator liner utilizes the horizontal moving component and the lifting component to enable the freezing mechanism to move left and right on the base, and in a forming state, the freezing mechanism is close to the refrigerating mechanism, and the lifting copper bar is lifted in place; in the demoulding state, the lifting copper bar descends to the right position, and the freezing mechanism is far away from the refrigerating mechanism. The distance between the refrigerating and freezing mechanisms is determined by the product and is fixed and invariable, the distance between the refrigerating and freezing main bodies of the connected refrigerator inner containers is smaller and is generally between 40 and 70 millimeters, the distance between the refrigerating main bodies and the freezing main bodies is fixed when the traditional vacuum forming mold is used for adsorption forming, the material between the two inner containers is very severely stretched and easily pulled and cracked, the thickness of a formed plate needs about 5.0 millimeters in order to meet the minimum wall thickness requirement of the product, the qualification rate is about 80 percent, and the traditional vacuum forming mold cannot meet the product requirement, so the invention designs the freezing main bodies to horizontally move when the vacuum forming mold of the connected refrigerator inner containers is designed, Increasing the forming starting distance between the refrigerating mechanism and the freezing mechanism, when the forming is started, more forming materials are arranged between the two mechanism bodies, the forming of the plate is facilitated, the requirement of the wall thickness of a product is met, when the die rises to a certain height, the die starts to contact with the formed plate, the main body of the freezing mechanism starts to slowly approach to the main body of the refrigerating mechanism under the action of a cylinder along with the continuous rising of the die, the speed is controlled by a pneumatic speed regulating valve, when the die rises, the freezing mechanism moves in place in a translation manner, the lifting copper bar starts to rise and stays in place, then the vacuumizing material is adsorbed and formed on the surface of the die, the method reduces the forming difficulty of the plate, the thickness of the formed plate is reduced to 3.2 mm from the original 5mm, the material cost is reduced by 36%, and the qualification rate of the product is improved to 99% from 80% of the traditional forming die. In contrast, the existing main body swinging mechanism pushes the main body to rotate along the hinge mechanism fixed on the die base through the air cylinder fixed on the die base, the vibration is larger, the fixed part runs for a long time and is easy to loosen, the reliability and the product quality of the die are affected, the main body swinging mechanism can only be applied to the die with relatively simple and smooth appearance, smaller main body, light weight and small inertia of the freezing main body, the swinging angle is limited, and the swinging main body cannot exceed the appearance of the die base. Compared with the existing main body swinging mechanism, the main body translation mechanism of the invention forms sliding fit with the sliding block fixed on the die base through the linear guide rail fixed at the bottom of the translation mechanism, the translation mechanism moves horizontally on the die base, the weight of the translation mechanism mainly acts on the linear guide rail and the sliding block, the horizontal moving cylinder only needs to overcome the sliding friction force of the translation mechanism moving on the linear guide rail, the cylinder diameter of the horizontal moving cylinder is small, the stroke of the horizontal moving cylinder can be determined according to the distance between the inner containers of the conjoined refrigerator, the distance between the inner containers of the conjoined refrigerator is small, the stroke of the horizontal moving cylinder is selected to be longer, and when the distance between the inner containers of the conjoined refrigerator is large, The stroke of the horizontal moving cylinder is short, so that the complexity of the moving body is not limited by the translation mechanism, and the horizontal moving cylinder is basically suitable for forming molds of vacuum liners of various connected refrigerators.
