摘 要

塑料是以树脂为主要成分的高分子有机化合物,树脂可分为天然树脂和合成树脂两大类,塑料大多采用合成树脂.塑料制件之所以能得到广泛应用,是由于它们本身具有的一系列特殊优点决定的.塑料工业是新兴的工业,是随着石油工业的发展应运而生的,目前塑料制件几乎已经进入一切工业部门以及人民日常生活的各个领域.塑料工业又是一个飞速发展的工业领域.我国的香港与深圳等地区,其模具工业主要是从事塑料模具的制造与塑料制件的生产.在江苏省、浙江省、上海市及其以南地区，尤其在浙江省从事塑料模具的制造与塑料制件的开发的个体企业也日益增多。本设计说明书对塑料模具设计的各种成型方法，成型材料的设计，成型，成型零件的加工工艺（主要有线切割，电火花加工，数控车床，加工中心），主要设计参数的计算，产品缺陷及其解决方法，模具总体结构设计及零部件的设计较详细的做了介绍。综上所述，塑料成型工业在基础工业中的地位和对国民经济的影响显得日益重要。
关键词：模具结构、浇注系统、加工工艺。

Abstract

Plastic is resin as the main component of macromolecule organic compounds, the resin can be divided into two categories, natural resin and synthetic resin, plastic mostly adopts the synthetic resin. Plastic parts are widely used, because they decided itself has a series of special advantages. Plastic industry is an emerging industry, is along with the development of oil industry arises at the historic moment, the plastic parts already in almost all industrial sectors and different areas of the People's Daily life. The plastics industry is a rapidly developing industry. Hong Kong and shenzhen and other areas in China, the mould industry is mainly engaged in the manufacture of plastic mold and plastic parts production. In the region south of jiangsu, zhejiang, Shanghai and, especially in zhejiang province is engaged in the manufacture of plastic mold and plastic parts of the development of individual enterprises are also increasing.This design manual molding methods of plastic mold design, the design of the molding material, molding, molding parts processing (mainly include wire cutting, edm, CNC lathes, machining centers), main design parameters, product defects and their solutions, mould structure and components of the overall design is presented in detail.To sum up, the status of plastic molding industry in basic and appear increasingly important impact on the national economy.
Keywords: mold structure, pouring system, processing technology.
