The mould injection design of charger shell

Abstract

This paper describes the design of an injection mold in detail, this injection mold is a charger shell mold. After analyzing the performance, molding and structural process of the material in the manufacturing process of the charger shell, the relevant molding equipment was selected. And the appropriate parting surface of the injection mold is selected, and the appropriate number of cavities are determined and their positions are arranged. At the same time, the design of each system and structure

in the forming process is analyzed and introduced in detail, including the design of the pouring system and the cooling system, as well as the orientation mechanism and the stripping mechanism. The material of the mold is also selected, and the relevant working parameters of the injection machine are given. Based on the detailed analysis and design, the paper explains in detail the working principle of the mold and the specific process of installation and commissioning, and analyzes and optimizes the problems that may arise in this process.

Keyword:injection mold; charger shell; three plate mold; pouring system;

stripping mechanism; fixed pitch classification mechanism.
