连接器壳体塑料注塑模具设计

摘要

本文是关于连接器壳体塑料注塑模具的设计，通过正确分析塑件工艺特点和ABS材料的性能后，最终设计出一副注塑模。塑料制品具有原料来源丰富,价格低廉，性能优良等特点。它在电脑、手机、汽车、电机、电器、仪器仪表、家电和通讯产品制造中具有不可替代的作用，应用极其广泛。注射成形是成形热塑件的主要方法，因此应用范围很广。

注射成形是把塑料原料放入料筒中经过加热熔化，使之成为高黏度的流体，用柱塞或螺杆作为加压工具，使熔体通过喷嘴以较高压力注入模具的型腔中，经过冷却、凝固阶段，而后从模具中脱出，成为塑料制品。

本文详细介绍了模具的浇注系统、模具成型部分结构、顶出系统、冷却系统、注塑机的选择及有关参数的校核等等设计。运用CAD、辅助工程PRO/E 等不同的软件分别对模具的设计、制造和产品质量进行分析。连接器壳体塑料注塑模具设计，采用一般精度，利用CAD、PRO/E来设计或分析注射模的成型零部件，浇注系统，导向部件和脱模机构等等。针对连接器的具体结构，该模具采用点浇口双分型面注射模具。由于塑件内侧有小孔，需要设置斜导柱。通过模具设计表明该模具能达到连接器的质量和加工工艺要求。综合运用了专业基础、专业课知识设计，其核心知识是塑料成型模具、材料成型技术基础、机械设计、塑料成型工艺、模具CAD\CAM等。

The connector shell plastic injection mold design

Abstract

This article is about the connector shell plastic injection mold design, through the technological characteristics of plastics article of correct analysis and the performance of ABS material, the final design out a pair of injection mold. Plastic products have rich raw material sources, low price, good performance, etc. It in computers, cell phones, cars, motors, electrical appliances, instruments and meters, household appliances and communications products manufacturing has irreplaceable function, is widely applied. Injection molding is the main method of forming thermoplastic parts, so the application range is very wide.

Injection molding is melt the plastic raw material into the cylinder through the heating, made of high viscosity fluid, pressurized with piston or screw as a tool, makes the melt through the nozzle at high pressure into mold cavity, after cooling and solidification stage, and then out of the mould, plastic products.

Mould gating system are introduced in detail in this paper, the structure of the molding part, ejector system, cooling system, selection of injection molding machine and related parameters of checking, etc. Design. Using PRO/E CAD, auxiliary engineering such as different software respectively to the mold design, manufacturing and product quality are analyzed. Connector shell plastic injection mold design, using the general accuracy and the use of CAD, PRO/E to design or analysis of forming parts of injection mould, pouring system, guide parts and demoulding mechanism, and so on. According to the specific structure of the connector, the mould adopts the point gate double parting surface injection mould. Because there are holes plastic parts inside, need to set up the inclined guide pillar. Through the mold design shows that the mould can achieve connector quality and processing technology. Integrated use of the professional basis, professional class knowledge is designed, its core knowledge is the plastic molding mold, material molding technology base, mechanical design, plastic molding process, mould CAD/CAM, etc
