1、.摘要模具生产技术水平的高低，已成为衡量一个国家产品制造水平高低的重要标志。塑料工业的飞速发展，对注塑模具的设计与生产提出了质量好、制造精度高、研发周期短等越来越高的要求，能否适应这种需求已成为模具生产企业发展的关键因素。模具技术是融合机械工程、计算机应用、自动控制、数控技术等学科为一体的综合性学科。本设计通过对开关面板塑件的结构分析，确定总体的设计方案，包括确定注塑模具分型面、型腔数目，以及设计浇注系统、温度调节系统和顶出系统等。详细地讨论了模具成型零件包括型芯、型腔的尺寸计算过程，重要零件工艺参数的选择与计算，推出、斜顶以及其它结构的设计过程。利用
2、软件完成模流分析，找出注塑成型过程中缺陷的种类及位置，提出解决的方法。设计方案在保证塑件质量与模具结构合理的前提下尽量使结构简单，生产加工成本低、易加工。关键词：开关面板；注塑模具；pro/e；浇注系统；注射机....ABSTRACTThetechniquelevelofmoldingtoolwhichhasbecameanimportantmarkingtomeasurethelevelofanationalproduct.Somehigherdemandssuchashighquality,highprecision,shorttimeofR&Da
