文档介绍：摘要
注塑成型工艺已经在我国的农业、工业、制造业、国防及日常生活等方面广泛的运用。为了探究注塑成型工艺的生产过程及其模具的设计制造过程,本次毕业设计参考相关书籍,结合生活实际,对整套注塑模具的生产设计过程进行详细探究。
本文将对塑料板凳的注塑模具设计,详细描述了整套模具的设计过程。主要内容包括塑件的基本介绍、塑件的结构及成型工艺分析、材料的选择及成型工艺、注射机的选择及校核、模具的工作及结构原理、浇注系统的设计、成型零件的设计、侧向分型抽芯机构的设计、合模导向机构的设计、温度调节系统的设计、排气系统的设计、推出机构的设计等。在正确的分析材料的特点和塑件的工艺特点后,运用三维软件对塑件和模具的设计,制造及质量进行分析;运用CAXA软件绘制完整的模具装配图和其主要零件图。此次设计综合运用多中专业基础知识、如模具设计与制造基本理论、机械设计、材料成型基础、塑性成型工艺、计算机基础技术、模具CAD/CAM等。
通过对整个模具设计的过程,进一步加深对注塑成型工艺的了解,同时也巩固了对成型工艺的类型、结构、工作原理等的理论知识,以及在实践中总结并掌握模具设计的关键要点及其设计方法。

Abstract
Injection molding process has been widely used in China's agricultural、 industrial、 manufacturing、defense and other aspects of daily life. In order to explore the injection molding process and mold production process design and manufacturing process, this graduation design reference books, combined with real life, the production of injection molds for the entire design process detailed inquiry.
This article will bench plastic injection mold design, detailed description of the entire mold design process. The main contents include a basic introduction to plastic parts, design selection and verification, working principle and structure of the mold, pouring system structure and plastic parts molding process analysis, choice of materials and molding process, injection machine, forming part of the design, side parting pulling mechanism design, design-anization designed to mold temperature control system, the design of the exhaust system, the introduction of design institutions. After the characteristics and process characteristics of plastic parts correct analysis of the material, the use of three-dimensional software for plastic parts and mold design, manufacturing and quality analysis; using CAXA software to draw plete mold assembly drawing and its major parts diagram. The design of the integrated use of multi-professional knowledge, such as mold design and manufacture of basic theory, mechanical design, material forming the basis of the plastic moldin
