摘 要

模具制造技术迅速发展，已成为现代制造技术的重要组成部分，如模具的CAD/CAM技术，模具的激光快速成型技术，模具的精密成形技术，模具的超精密加工技术。塑料产品从产品设计到成型生产包括塑料制品设计、模具设计、模具制造和注塑工艺参数选择等几个主要方面。长期以来，模具设计主要依赖设计者的经验和技巧，设计合理与否、制品有无缺陷只有通过试模才知道，致使模具及塑料产品的设计与制造周期长、成本高，产品质量不易保证，废品率高，缺乏市场竞争力。本设计介绍了电动剃须刀外壳模具设计，该注射模采用了一模两腔的结构。

本文在进行设计之前首先采用Pro-E分析软件对零件进行分析，该分析主要目的是在分析成型工艺合理性的同时，优化型腔布局形式，根据分析结果确定合理的成型工艺和较好的型腔布局形式。然后就可以在Pro/E设计软件的EMX模块中进行模具结构的设计了，模具各个系统的设计都是在这个模块中进行的。本文后面着重介绍了塑件的工艺性分析、浇注系统的设计、排气系统、导向与定位机构、脱模机构、侧向分型抽芯系统的设计、成型零件的设计、标准模架选择、温度调节系统、各参数的校核等。并使用AutoCAD软件绘制总装配图及模具主要的零件图。同时简单的编制了主要模具零件的加工工艺过程卡。

Abstract

Die & mould manufacturing technology rapid development, has become a modern manufacturing technology of the important component. Such as mould CAD/CAM technology, mould of laser rapid prototyping technology, mould precise forming technology, die ultra-precision processing technology. Plastic products from product design to molding production including plastic products design, mold design, mould manufacturing and injection molding process parameter selection and so on several aspects. Long-term since, mold design mainly depends on the designer's skill and experience, design reasonable or not, products have only by trying to mold defects know, cause mould and plastic product design and manufacturing cycle is long, the cost is high, the product quality is not easy to guarantee, scrap rate is high, the lack of market competitiveness. This design is introduced the electric razor shell mould design, this injection mould adopted a module and two cavity structure.

This article before the first design Pro-E analysis software for parts to carry on the analysis, the analysis of the main purpose is on the analysis of the forming technology of rationality and at the same time, optimizes the cavity layout forms, according to the results of analysis the determination of reasonable molding technology and good cavity layout form. And then you can in Pro/E of design software EMX module in the design of die structure, mould all the design of the system are in this module. Later in this paper mainly introduces the technology of plastic parts analysis, the design of gating system, exhaust systems, orientation and the position of the institutions, remolding mechanism, side parting core-pulling system design, the design of its molding part, standard formwork selection, temperature control system, each parameter of the check. And use AutoCAD software rendering drawings and main mould of total drawing. And simple compiled the main mould parts processing process card.

Key words: Injection mould; Razor shell; Pro-E; Injection molding; Mold design
