Plug-free box body foaming mold

Abstract

The invention discloses a block-free foaming mold for a box body. The foaming mold is provided with a foaming mechanism for cooperating with an upper mold and a lower mold to form a forming cavity for an invisible beam on the box body to be formed. Set the bottom push plate, front push plate and rear push plate that can move downward, forward and backward respectively against the inner wall of the box to be formed from the bottom, front and rear sides, so as to cooperate with the upper mold and lower mold Cooperate to form the forming cavity of the invisible beam to be formed. When the foaming mold is in use, it is only necessary to make the driving mechanism drive the mounting plate to move horizontally, left and right, and there is no need to manually add plugs, which improves the production efficiency of the foam molding of the box to be formed and reduces the labor of the workers. It also reduces the cost caused by adding plugs, and at the same time ensures the precision of the invisible beam forming and improves the quality stability of the foam molding of the box. The foam mold is easy to use and has a good comprehensive use performance.

Description

technical field [0001] The invention relates to a block-free foaming mold for a box body. Background technique [0002] The foaming of the refrigerator box is an important link in the refrigerator manufacturing process, and the quality of the box foaming mold directly affects the product quality of the refrigerator. Conventional refrigerators are provided with a plurality of doors, and cross beams are generally provided between the doors. In some refrigerators, in order to make the chamber between the two doors a connected structure, the beam between the doors is set as an invisible beam, that is, a column-shaped beam is installed on the refrigerator near the side where the door is installed, and the invisible The inner cavity of the refrigerator box on both sides of the beam and at the bottom is a connected structure. When foaming a refrigerator box with invisible beams, the usual practice is to manually place a craft block under the invisible beams in the pre-assembled ...

AI Technical Summary

Problems solved by technology

This kind of foaming method has low production efficiency, high labor intensity, and increases the cost of production auxiliary materials, and the installation accuracy of the plug cannot be guaranteed, resulting in unstable foaming quality, and when the plug is damaged will affect the production

In addition, it is more troublesome to clean the adhesive tape inside the box
