设计简介
摘 要
世界范围内制造业的竞争变得越来越激烈。企业高效率、低消耗地为顾客提供个性化、高质量产品的能力，已成为企业竞争能力的重要标志。模具被称为“工业之父”，模具质量的高低，将直接影响到产品的质量、产量、成本，新产品投产及老产品更新换代的周期，企业产品结构调整的速度与市场竞争力，因此经济形势对模具的质量提出了越来越高的要求。
塑料模具的发展是随着塑料工业的发展而迅速发展起来的。近年来，人们对各种设备和用品轻量化及美观和手感的要求越来越高，这就为塑料制品提供了更为广阔的市场。塑料制品要发展，必然要求塑料模具随之发展。
在塑料模具发展日益迅速的今天，注塑模具无疑已经成为塑料模具发展的先进代表，在塑料模具中占据着核心的地位。
本次设计为一个塑料灯座产品的注塑模具。通过对该产品结构和性能的全面分析，设计了一副一模四腔的注塑模具。该说明书详细地叙述了该产品模具成型零件的设计和加工工艺过程，重要零件的工艺参数的选择与计算，推出机构与浇注系统以及注塑模具其它结构的设计过程。

Injection mold of lamp holder
Abstract：
Worldwide competition is becoming increasingly fiercely among manufacturing industry. Providing individualized product for customers with high efficiency, low consumption and high quality ,has become an important symbol of competitiveness for a modern enterprise. Mould has been known as "the father of industrial”.The quality of mould, will directly affect the quality of products, production, cost, production of new products and product replacement cycle of old, the pace of structural adjustment enterprise products and market competitiveness and economic situation the quality of the molud the ever-increasing demands.
With the development of plastics industry ,plastic mould t is developing more and more rapidly.In recent years, the demands of people for all kinds of equipments and supplies lightweight and beautiful and the demand of feel is becoming higher and higher, which provides a broader market for the plastic products. The development of plastic mould, it is necessary to follow the development of plastic products.
Plastic mold is developing increasingly today, no doubt injection mould plastic mould has become the representative of the development of advanced, in the plastic mould to occupy the core status.
This design is a plastic injection mold for a Plastic Product of lamp holder.A set of mould with one module and four cavities has been designed. Through a comprehensive analysis of the structure and properties. A detailed description of molding part and technological process, the selection of technological parameters and calculation of the important part .At the same time ,a design for its molding part, injection system ,rejecting mechanism of injection mold and other make-up of the mould, as well as the working process of the mould, were specified in detail.
