摘要
塑料工业是一门新兴产业,自塑料问世后几十年,塑料来源丰富,制作方便及成本低廉、金属零件塑料化的发展很快,在机械电子、国防、交通、通讯、建筑、农业、轻工业和日常生活用品等行业中都得到了广泛的应用,对塑料模具要求量增加。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。
本设计介绍了注射成型的基本原理,特别是单分型面注射模具的结构与工作原理,对注塑产品提出了基本的设计原则;通过对塑件工艺的正确分析,设计了一副一模两腔的塑料模具。详细地叙述了模具成型零件包括前模板、前模仁、后模板、后模仁、后模镶件等的设计与加工工艺过程,重要零件的工艺参数的选择与计算,推出机构与浇注系统以及其它结构的设计过程,综合地处理好产品外观要求与浇口位置及脱模方式之间的问题,并对试模与产品缺陷作了介绍。
关键词:模具设计、常用塑料
Abstract
Plastics industry is an emerging industry, since several decades after the advent of plastic, plastic source of rich, convenient and low-cost production, metal parts plastic of the developed rapidly, in machinery and electronics, defense, transportation, communication, construction, agriculture, light industry and daily necessities and other industries have been widely used, on the plastic mold requested increase. Therefore, the research injection 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 principle of injection molding, especially the single parting surface of injection mould structure and working principle of injection molding product, puts forward the basic design principle of plastic parts; through the correct analysis of the technology, designed mold two cavity of the plastic mold. Detailed account of the molding parts includes a front template, the former mold, mold, after the mold, after the mold inserts in the design and fabrication process, an important part of the process parameter selection and calculation, the agency launched and pouring system and other structural design process, prehensive treatment of the appearance of the product requirements and gate location and demoulding ways between issues, and the tryout and product have been introduced.
Key Words: Mold Design and Manufacturing、Conventional Plastic Materials
