文档介绍：1 摘要塑料工业是当今世界上增长最快的工业门类之一,而注塑模具是其中发展较快的种类,因此,研究注塑模具对了解塑料产品的生产过程和提高产品质量有很大意义。本设计介绍了塑料模具的基本结构和注塑模的一些典型结构,注射成型的基本原理,对注塑产品提出了基本的设计原则;详细介绍了注射模具浇注系统和凹凸模尺寸的设计过程,最后介绍了当今世界上最为普及的三维 CAD/CAM 系统标准软件 SolidWorks 。通过本设计,可以对注塑模具有一个初步的认识,注意到设计中的某些细节问题,了解模具结构及工作原理。关键词:塑料模具,注塑模,典型结构。 2 Abstract : plastic industry is in the world grows now one of quickest industry classes, but casts the mold is development quick type, therefore, the research casts the mold to understand the plastic product the production process and improves the product quality to have the very big significance. This design introduced the basic structure cf plastic mold and some typical structure and the principle of work, to cast the product to propose the basic principle of design; Introduced in detail the cold flow channel injection evil spirit mold pours the system and the design process of concavo-convex mold size. Finally introduced now in the world the most popular three dimensional CAD/CAM system standard software SolidWorks. Through this design, may to cast the mold to have a preliminary understanding, notes in the design certain detail question, understands the mold structure and the principle of work. Key word: The plastic mold , injection mold , typical structure 3 目录第一章模具设计总述…………………………………………… 1 模具工业在国民经济中的地位…………………………………………… 1 我国模具技术的现状及发展趋势……………………………………………… 2 第二章各类塑料模具及其特点……………………………………… 6 各种模具的分类和占有量………………………………………………… 6 各类塑料模具结构………………………………………………………… 7 注塑模具的典型结构……………………………………………………… 13 第三章某零件的塑料模具结构…………………………………… 17 注塑件的设计……………………………………………………………… 17 功能设计……………………………………………………………… 17 材料选择……………………………………………………………… 17 结构设计……………………………………………………………… 21 塑件的尺寸精度及表面质量………………………………………… 21 注塑机的选择……………………………………………………………… 22 注塑机简介…………………………………………………………… 22 注塑机基本参数……………………………………………………… 23 选定注射机………………………………………………………… 24 模具结构设计……………………………………………………………… 24 总体设计……………………………………………………………… 24 某零件塑料模具设计………………………………………………… 25 第四章模具的三维造型…………………………
