摘要

模具是近代工业大量生产时所经常使用的一项重要工业与技术。模具制造的精密程度和技术层次，对于所生产的产品品质，生产原料的有效应用，和生产能力的提高等方面，都有非常大的的影响。模具业在工业中有着非常重要的位置，而模具业又是以塑料模为主。跟我们生活离不开的的家电产品，电信产品及汽车零件中，绝大部分都是塑料制品。科技文明的进步，我们的生活水平也在不断提高，工业社会里也会有各产品推陈出新。想要实现此目的，就必须用模具实现大量生产，这样才能够尺寸稳定，经济实用。

该设计的设计题目是盖塞注塑模具设计，由于盖塞的结构特点和本质特性，选择它的生产类型，该塑件的生产为大批量生产、PS（聚苯乙烯）塑料的成型性能特点以及盖塞的结构的特点，设计成盖塞注塑模具较为合理。由于盖塞为日常的通用零件，对其精度要求并不是很高。但是由于这种塑件的特殊的结构原因，在成型的时候需要成型外部螺纹，使模具结构变得相对复杂，从而增加了装配时的难度。为了生产时成型螺纹，模具结构上需要采用螺纹抽芯机构，为方便螺纹型芯的抽出，模

具采用的是齿轮齿条抽芯机构，即可采用普通卧式注塑机，由于塑件对精度要求不高，成型零件加工也比较容易。

本模具采用的是一模两腔，但是总体上该模具机构比较简单，制造相对容易，生产周期不是很长，从而节约了企业公司单位的加工成本，大大的缩短了模具制造周期。

关键词：外部螺纹；螺纹抽芯；齿轮齿条机构

Abstract

Mold is an important industrial and techniques of modern industrial mass production frequently used. Mold manufacturing sophistication and technical level, for the production of quality products, effective use of raw materials, and production capacity increase, etc., have a very big impact. Mold industry in the industry has a very important position, and the plastic mold industry in turn is based. Now we can not live without home appliances, telecommunication products and automobile parts, most are plastic products. Technological advances of civilization, and our standard of living is also rising, industrial society will have all product innovation. Want to achieve this goal, we must achieve mass production mold, so as to dimensionally stable, economical and practical.

The design of the design problem is stoppered injection mold design, due to the structural characteristics and the essential characteristics stoppered and choose its type of production, the production of plastic parts for the mass production, PS (polystyrene) and plastic molding

Features Features cover plug structure, designed to cover the plug injection mold is more reasonable. Since the cover plug for the everyday common parts, its precision is not very high. However, due to structural reasons for this special plastic parts, molded in molding outer thread when needed, so that the mold structure becomes relatively complicated, thus increasing the difficulty during assembly. For the production of thread forming, the mold structure requires the use of thread pulling mechanism, to facilitate the extraction of the core thread, using the rack and pinion mold core pulling, you can use ordinary horizontal injection molding machines, due to the precision plastic parts not high, molded parts machining easier.

The mold is used in a two cavity mold, but overall the mold body is relatively simple, relatively easy to manufacture, not very long production cycle, thus saving the cost of processing enterprises unit, greatly reducing the mold manufacturing cycle.
