摘要
在现代机械制造业中，模具工业已成为国民经济中一个非常中重要的行业，许多 新产品的开发和生产，在很大程度上依赖于模具制造技术，特别是在汽车、轻工、电 子和航空等行业中尤显重要。模具作为一种高附加值和技术密集型产品，其技术水平 的高低已成为衡量一个国家制造水平的重要标志之一， 因此它关系到产品的质量和经 济效益的提高，直接影响国民经济中的许多行业的发展。而塑料工业的发展依赖于模 具工业. 本设计主要是电线盒的注射模具设计。通过对塑件进行工艺的分析及其结构分析，从 产品结构工艺性,具体模具结构出发,对模具的浇注系统、模具成型部分的结构、顶出 系统、注射机的选择及有关参数的校核都有详细的设计。 关键词：注塑模具；注射机

Abstract
In modern mechanical manufacturing industry, mould industry has become a very important industry in national economy, a lot of new products development and production, to a large extent depends on die manufacturing technology, especially in the automotive, light industry, electronics and aerospace industries seems especially important. Mould as a high value-added and technology intensive products, its level of technology has become a measure of a country manufacturing level one of the important marks, so it is related to the quality of the products and the improvement of economic efficiency, directly influence the development of many industries in national economy. While the development of plastics industry relies on the mould industry. This design is mainly electricity box injection mold design. Through to the plastic parts for process analysis and structure analysis, from the product structure craft, specific die structure, the mould of gating system, molding part of the structure, the ejection system, selection of injection machine and related parameters of checking all have detailed design Keyword：Plastic injection mould；Plastic injection mould machine；
