PE material injection molding process

Abstract

The invention belongs to the technical field of PE material injection molding, and particularly relates to a PE material injection molding process. An injection mold comprises an inner mold and an outer mold; a bottom plate is fixedly connected to the bottom of an auxiliary plate; a motor driving shaft penetrates through the bottom plate and is fixedly connected with the inner mold; first electrictelescopic rods which are uniformly arranged are fixedly connected to the upper surface of a supporting plate; first sliding grooves which are uniformly distributed are formed in the inner wall of the inner mold above the supporting plate; a first sliding rod is connected in each first sliding groove in a sliding manner, and the first sliding rods are fixedly connected with the uniformly arrangedfirst electric telescopic rods; and arc-shaped grooves which are uniformly arranged are formed in the inner wall of the opposite side of each first sliding rod. The PE material injection molding process is mainly used for solving the problems that as gas in raw materials is not completely removed in the injection-molding process of a PE pipe at present, holes are formed in the injection-molded pipe, and burrs are generated on the inner wall and the outer surface of the PE pipe after the injection molding is finished, so that pollution is caused 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

[0006] 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.
