Automatic demolding reverse injection mold and use method

Abstract

The invention provides an automatic demolding reverse injection mold and a use method. The mold comprises an upper mold body, a lower mold body, an upper mold plate for fixing the upper mold body and a lower mold plate for fixing the lower mold body. The mold further comprises an ejection mechanism. The ejection mechanism comprises a movable mold core for moving a product and an ejector pin plate for pushing the movable mold core to move. The ejector pin plate and the movable mold core are located on the two sides of the upper mold body respectively. The ejector pin plate is provided with multiple shutters for being connected with the lower mold plate. Multiple sleeves are arranged on the portions, corresponding to the shutters, of the lower mold plate. Each sleeve is arranged on the corresponding shutter in a sleeving manner to form containing space for containing the lower mold body and the upper mold body. The product can be subjected to rapid demolding and is not likely to be deformed or damaged, and more importantly, production cost is low.

Description

technical field [0001] The invention relates to the technical field of demoulding mechanisms, in particular to an automatic demoulding flip-chip injection mold and a method for using it. Background technique [0002] Mold is an indispensable and important tool in injection molding. Injection molding is to inject hot-melt plastic material into a closed cavity with the desired shape in the mold at high speed. After the plastic material is cooled and solidified, the mold is opened to eject the solidified plastic product. , to obtain the processing method of the shaped product. Since the injection molding processing method has the characteristics of low molding cost, short molding cycle, simple molding process and easy molding of plastic products with complex shapes, it is widely used in the field of plastic product applications. [0003] At present, the thermoplastic polyurethane elastomer rubber (being called for short TPU soft) plastic injection mold structure of existing fo...

AI Technical Summary

Problems solved by technology

[0004] 1. When demolding plastic products, automatic and complete demoulding cannot be achieved, and manual operation is required to assist demoulding;

[0005] 2. When manually assisted demoulding, because the overflowing plastic coating around the plastic product is stressed on the movable mold core, it is difficult to demould, and the uneven force of manual operation may easily lead to deformation and damage of the plastic product. ;

[0006] 3. Manual assisted demoulding takes a long time, the operator's operation is too cumbersome, the workload is heavy, the manufacturing completion cycle of the whole product is long, the efficiency is low and the quality is high, resulting in high production costs
