Problems solved by technology

[0004] (1) During the molding process of the traditional thermal insulation foam plastic packaging box, due to the limitation of the mold, the thermal insulation foam plastic packaging box cannot be quickly demoulded to the formed thermal insulation foam plastic packaging box after molding, so that Reduced demoulding efficiency
[0005] (2) During the forming process of the traditional thermal insulation foam plastic packaging box, the thermal insulation foam plastic packaging box after molding is easy to fall into the mold during the blanking process, which reduces the working efficiency of blanking

Abstract

The invention relates to a forming mold for a heat insulation foamed plastic packaging box. The forming mold comprises a workbench, a first mold body, a fixing device and a second mold body. The firstmold body is arranged at the left end of the top of the workbench, the second mold body is arranged above the first mold body, and the fixing device is arranged on the outer side of the first mold body. The first mold body comprises a concentric-square-shaped plate, hollow plates, an air inlet frame, a spring air bag, a horizontal plate, a limiting groove and an air pump, and the concentric-square-shaped plate is fixedly mounted at the top of the workbench. Through cooperation of the arranged workbench, first mold body, fixing device and second mold body, injection molding is carried out after the first mold body and the second mold body are compounded, after cooling forming, the first mold body and the second mold body are used for conducting rapid demolding on the formed heat insulationfoamed plastic packaging box, and therefore the demolding work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of foamed plastic packing boxes, in particular to a molding die for heat-insulating foamed plastic packing boxes. Background technique [0002] Foam plastic is a kind of polymer material formed by dispersing a large number of gas micropores in solid plastic. It has the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc., and its dielectric performance is better than that of matrix resin. It has a wide range of uses. Almost all kinds of plastics can be made into foamed plastics, and foam molding has become an important field in plastics processing. [0003] In the process of forming the thermal insulation foam plastic packaging box, due to the limitation of the mold, the following problems exist in the actual operation process: [0004] (1) During the molding process of the traditional thermal insulation foam plastic packaging box, due to the limitation of the mold, the...
