摘要本文以按钮组件的注塑成型作为研究对象，对按钮组件产品注塑成型工艺、模具设计等进行了较为系统的设计。按钮组件整体体积小、结构也较为复杂，因此对注射成型模具和成型工艺的要求比较高。按钮组件注射模具设计制造的最大难点在于分型面、浇注系统、脱模机构的设计。83530

本课题中所涉及的尺寸、数据和产品结构均来自工厂企业生产的实际图纸。以工厂实用为原则，进行注塑模具的设计。本设计首先全面的论述了塑料，模具，及Pro/ENGINEER的基本设计理论，之后主要应用Pro/ENGINEER 5。0来进行按钮塑料模具的零件造型和模具设计，最后通过对塑料制件的各种参数进行运算，使用EMX 工具来进行调用模架进行最终设计。

Abstract

In this paper, the injection molding of button component is used as the research object, The injection molding process and die design of the button assembly are designed。 Button components have small volumes, the structure is also more complex, so the requirements of injection molding mold and molding process is relatively high。 The biggest difficulty is the design of parting surface, gating system and the ejection mechanism。

Button components have small volumes。 The structure is also more complex, so the requirements of injection molding mold and molding process is relatively high。 The biggest difficulty is the design of parting surface, gating system and the ejection mechanism。 The size, data and product structure of the project involved in this subject are from the actual drawing of the factory production。 With the principle of the factory as the principle, the design of the injection mold。 The design of the first comprehensive discussion of the plastic, mold, and the basic design theory of Pro/ENGINEER, after the main application of Pro/ENGINEER 5 to carry out button plastic mold parts design and mold design, Finally, through the calculation of various parameters of plastic parts, use the EMX tool to make the call for final mould design。
