继电器外壳注塑模具设计

摘要：模具工业的发展，日益受到人们的重视和关注。“模具式工业生产的基础工艺装备”也已经取得了共识。在电子、汽车、电机、电器、仪器、仪表、家电和通信等产品中，60％～80％的部件都要依靠模具成型。本论文介绍的是电磁继电器外壳的注塑模具设计。

本论文详细介绍了整个模具的设计过程，对各机构和系统进行了详尽的分析，包括模具结构设计、浇注系统的设计、冷却系统设计、脱模机构设计、排气系统设计、抽芯机构设计，合模机构设计，导向机构设计等。除此之外还介绍了注塑材料成型工艺和性能，以及注塑机的选用和对部分参数的校核。

此设计多采用标准件，结构设计紧凑，目的为了降低模具的制造成本，提高生产效率。设计过程中使用了AutoCAD, UG等计算机辅助软件绘制了各主要零件图、制品图、以及大量结构设计图，大大缩短了设计的周期。

Relay shell mold design

Abstract:The development of die and mould industry，Increasing attention and concern。"The mold type industrial production process equipment foundation" has achieved consensus. In electronics, automobile, motor, electric appliances, instruments and meters, home appliance and communication products, 60% ~ 80% of its molding part should rely on. This paper introduces the electromagnetic relay is the shell injection mold design。

This paper introduced the design process, the mould of organizations and system for a detailed analysis, including the design of die structure and the design of gating system, cooling system design, design, exhaust system demoulding mechanism design, core-pulling mechanism design, mould design, the design of steering mechanism etc. In addition also introduces the injection molding technology and material performance, as well as the selection and injection of some parameters of the check.

This design is used more compact structure design, mould, in order to reduce the cost of manufacture, improve production efficiency. The design process using AutoCAD, UG software rendering such computer aided the major parts graph, products and design, structural design, greatly shorten the cycle.
