A pe material injection molding process

Abstract

The invention belongs to the technical field of injection molding of PE materials, specifically a PE material injection molding process; the injection mold includes an inner mold and an outer mold; the bottom of the auxiliary plate is fixedly connected with a bottom plate; the drive shaft of the motor passes through the bottom plate It is fixedly connected with the inner mold; the upper surface of the support plate is fixedly connected with the first electric telescopic rods arranged uniformly; above the support plate, there are first chute slots evenly arranged in the inner wall of the inner mold; each of the first slides The grooves are all slidably connected with first sliding rods, and the first sliding rods are fixedly connected with the evenly arranged first electric telescopic rods; the opposite side of each first sliding rod is provided with a Uniformly arranged arc-shaped grooves; the present invention is mainly used to solve the problem that in the process of injection molding PE pipes, the gas in the raw materials is not completely removed, resulting in holes in the injected pipes, and at the same time, the inner wall of the PE pipes after injection molding is completed. And the outer surface will produce burrs, which will cause pollution problems in the PE pipe.

Description

technical field [0001] The invention belongs to the technical field of PE material injection molding, and specifically relates to a PE material injection molding process. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method, and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is achieved through injection molding machines and molds. Injection molding machines are also Injection molding machine or injection machine, which is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, the invention proposes a PE material injection molding process. The invention is mainly used to solve the problem that the gas in the raw material is not completely eliminated in the current process of injection molding PE pipes, which leads to the occurrence of gas in the injection molded pipes. There are holes, it is easy to crack, etc. At the same time, after the injection molding of the PE pipe, the inner wall and the outer surface will have burrs, which will cause pollution in the PE pipe.
