Foaming mold of refrigerator door body

Abstract

The invention relates to a foaming mold of a refrigerator door body. The foaming mold comprises an upper mold assembly and a lower mold assembly; the upper mold assembly comprises an upper mold base,an upper movable barrier strip and a guide piece, wherein an upper mold cavity with a bottom opening is defined by the upper mold base and the upper movable barrier strip; the lower mold assembly comprises a lower mold base and a lower movable barrier strip, wherein a lower mold cavity with an upper opening is defined by the lower mold base and the lower movable barrier strip; and when the upper mold cavity and the lower mold cavity perform mold closing, the upper movable barrier strip extends into the inner side of the lower movable barrier strip, the lower movable barrier strip extends intoa gap between the guide piece and the upper movable barrier strip and is extruded by the guide piece, so that the lower movable barrier strip drives the upper movable barrier strip to rotate inwards together. According to the foaming mold, the upper movable barrier strip abuts against the side wall of a step of an end cover, the lower movable barrier strip abuts against the lower portion of the end cover, the end cover, a door shell and a door inner container are accurately positioned through the upper movable barrier strip and the lower movable barrier strip, so that the mounting and clampingprecision of all parts of the door body is guaranteed; and the manual operation is not needed, so that the production cost is reduced.

Description

technical field [0001] The invention relates to the field of refrigerator manufacturing, in particular to a foaming mold for a refrigerator door body. Background technique [0002] Foam molding is to directly fill the foaming liquid into the mold, heat it to melt, and form a gas-liquid saturated solution. Through nucleation, a large number of tiny bubble nuclei are formed, and the nuclei grow to make foam plastic parts. [0003] The refrigerator door body is composed of a door shell, a door liner, upper and lower end covers and foam plastic parts. The upper and lower end covers have card slots, which are respectively inserted at both ends of the door shell. The installation of the door liner and foam plastic parts requires a mold. Put the assembled upper and lower end covers and door shell on the lower mold of the mold, and the door The liner is placed on the upper mold of the mould. When the mold is opened, the foaming machine injects the set foaming liquid between the doo...

Problems solved by technology

This method is easy to cause errors in the placement position, and it is easy to cause deformation of the end cover, resulting in the scrapping of the door body, resulting in waste of materials, and manual work increases the production process.

The waste of materials and the increase of production processes increase the cost of production
