Refrigerator door liner foam mold

Abstract

The invention belongs to the technical field of refrigerator door liner molding, and in particular relates to a refrigerator door liner foaming mold, which includes an upper mold and a lower mold, and the upper mold and the lower mold respectively press the door liner from both sides of the door liner to prevent foaming During the process, the door liner expands and deforms, and the side of the door liner provided with the clamping boss fits with the upper mold. , the flap can press the side wall of the door liner under the clamping boss, and when the upper and lower molds are opened, the flap can be flipped to the side away from the clamping boss, so as to avoid the clamping boss demoulding. The invention adds a flap structure to the technology of the traditional foaming mould. The flap can effectively support the dead corner of the door liner during the foaming process. mold; the invention effectively improves the foaming quality and yield of the door liner.

Description

technical field [0001] The invention belongs to the technical field of forming refrigerator door linings, and in particular relates to a foaming mold for refrigerator door linings. Background technique [0002] The structure of refrigerator door liner with fruit box is as follows figure 1 As shown, there is a raised ridge on the inner side of the door liner, and a locking boss for fastening the fruit box is provided on the raised ridge. The space on the block is opened to the top of the block. This mold is prone to foaming and deformation during use, which will bring certain losses to the manufacturer. The reason for this problem is that the depth direction of the door liner is deeper, much deeper than the ordinary door liner, and the liner is drawn deeper during the blistering process, resulting in too thin wall thickness of the liner after forming, and the fruit box will be damaged when it is foamed. Due to the oversized size of the space at the place where the card tabl...

[0002] The structure of refrigerator door liner with fruit box is as follows figure 1 As shown, there is a raised ridge on the inner side of the door liner, and a locking boss for fastening the fruit box is provided on the raised ridge. The space on the block is opened to the top of the block. This mold is prone to foaming and deformation during use, which will bring certain losses to the manufacturer.

The reason for this problem is that the depth direction of the door liner is deeper, much deeper than the ordinary door liner, and the liner is drawn deeper during the blistering process, resulting in too thin wall thickness of the liner after forming, and the fruit box will be damaged when it is foamed. Due to the large size of the space at the place where the card table makes way, it cannot withstand the pressure of the foaming liquid and is deformed
