摘  要

 注射模的结构是由塑件的复杂程度和注射机的形式等因素决定的，凡是注射模均可分为动模和定模两大部分。注射时动模和定模闭合构成型腔和浇注系统，开模时动模与定模分离，取出塑件。模具在制造业中的地位越来越高，模具技术水平的高低，已成为衡量一个国家制造业水平高低的重要标志。
 本文介绍了注塑模的整个设计流程，分析塑件、选取注射机并作出部分参数的校核，然后是注塑模的整体设计，包括成型塑件几何形状和尺寸的成型部分及其零部件设计、输送熔融塑料的浇注系统设计、排出影响塑件精度气体的排溢与引气系统设计、这里只进行冷却系统设计的温度调节系统设计、分离并取出成型塑件的脱模机构设计以及模架设计。
 范文最后阐述了此次设计的心得体会。
关键词：注塑模设计; 模具; 塑件; 冷却系统

Abstract

 Injects the mold the structure is by models complex the degree andfactor decision and so on injection machine form, every is injects themold to be possible to divide into moves the mold and decides the moldtwo major parts. When injection moves the mold and decides the moldclosed constitution cavity and pours the system, operates when themold moves the mold with to decide the mold to separate, takes outmodels. Mold manufacturing in the increasingly high status and die level of technology, has become a national manufacturing measure the level of the important signs .
 This paper introduces, the whole design process of injection mould is introduced, that is, analysis plastic part, choose injection machine with some of its parameters being checked so as to satisfy design demands, then the injection mould overall design is introduced, such as the forming parts and components design forming plastic part’s geometry and dimension, the pouring systems design transporting melt plastics, the overflow and bleed system design discharging air which affects plastic part’s precision, the temperature adjusted system design only designing the cooling system here, demould mechanism design isolating and retrieving already molding part, and mould-frame design.
 Experiences are expounded in the end of the paper.
 Key  words : Injection mold design;  Mold;  Structural plastics;  Cooling system
