复印机小端盖注塑模具设计

摘要

塑料工业是当今世界上增长最快的工业门类之一，而注射模具是其中发展较快的一种。因此，研究注射模具对了解塑料产品的生产过程和提高产品质量有很大意义。

本文主要是设计复印机小端盖的注射模具，论述了注射成型的基本原理，特别是单分型面注射模具的结构设计，详细介绍了注射模具的成型工艺及设备选择、浇注系统、抽芯机构和成型零部件的设计过程，并对模具制造工艺要求做了说明，最后通过CAD软件绘制出模具图。

通过本设计，可以对注射模具有一个初步的认识，注意到设计中的细节问题，了解模具结构及工作原理，系统的复习了大学四年所学的专业知识。

Design of injection mould machine small end cover

Abstract

Nowadays plastics industry is to increase one of the quickest industry category in the world, injection mould is to develop quicker among them , therefore studies the injection mould has very big meaning to knowing plastic product procedure of production and raising product quality.

This paper is designed Copier small end cap injection mould , discussed the basal principle injection mould, especially One-surface injection mold design , Have introduced the molding handicraft injecting a mould detailedly、equipment Selection、 feed system、Pulling mechanism and molding part design process, As well as demanded an explanation for mold manufacturing technology, Finally draw out the mould picture by CAD software.

During this design, I can have a preliminary understanding of Injection mould, note the details, know Die structure and operating principle, Review of the professional knowledge of the four-year study .

Key words: injection mould; injection mould process; mould designing;divides the profile
