Description
Technical Field
The application relates to the technical field of household appliances, in particular to a back inclined drawing mechanism for a refrigerator foaming mold and the foaming mold.
Background
With the continuous improvement of living standard, the demands of consumers on the usability of the refrigerator are also continuously improved. At present, in order to improve the heat preservation effect, a vacuum insulation panel (VIP panel) is additionally arranged between the shell and the liner of the refrigerator body, the vacuum insulation panel (VIP panel) is made of a material formed by compounding a filling core material and a vacuum protection surface layer, the heat conductivity coefficient is very low, and the refrigerator has the advantages of thin thickness, small volume and light weight of a heat preservation layer.
The foaming of the refrigerator body is an important key link in the production process of the refrigerator, and is influenced by factors such as preassembled parts, dimensional errors of the refrigerator body, uneven thickness of the liner, large dimensional fluctuation, local deformation and the like in the foaming process, and the problem of local bulge deformation easily occurs on the large back surface of the foamed refrigerator body and the mounting surface of the air duct. During the subsequent refrigerator assembly, the assembly of parts inside the refrigerator body such as the shelf, the partition plate, the air duct panel and the like can be influenced. Because the foaming position of the box body bulges and inclines, the sealing with the mounting surface of the air duct part component is not tight, and the phenomenon of cold leakage is easy to occur, so that the refrigerating effect of the refrigerator can be influenced.
The existing method for solving the problem generally adopts a mechanical lifting rod structure or a full pneumatic expansion structure, but the back part mode of the box hair mold adopts an integral dead structure or a local follow-up structure, so that the problem of the back bulge of the refrigerator cannot be effectively solved. In addition, when the design of the cylinder ejection structure is adopted in the industry, the die structure is too complex, and the cylinders are distributed in the die cavity, so that the quick size adjustment and daily maintenance in the production process are not facilitated.
