摘要:随着高分子聚合材料在医疗、食品、电子电器、仪器仪表等各个领域的广泛应用,其产品的品质对注塑成型工艺的依赖程度越来越高,但随着原材料价格的上涨用工成本的增加,市场的激烈竞争,为了保住市场份额,迫使生产企业不得不挖掘潜力降成本,改变传统生产模式通过实行自动化改造改变传统人工密集、环境脏乱型生产模式,采用集中供料系统、机械手、模具监视器,配以传送机构等,以提高生产效率及产品质量,从而增强企业的竞争力,同时为企业树立现代化工厂的形象,从“制造”逐步向“智造”转变。

Abstract: with the polymer materials in medical treatment, food, electronic appliances, instruments and meters and other fields are widely used, its product quality more and more dependent on plastic injection molding process is high, but with the increase of raw material prices rising labor costs, to the fierce competition in the market, in order to retain market share, forced production enterprises to explore potential cost reduction, change the traditional mode of production by implement automation transformation to change traditional labor intensive, filthy environment, production mode, adopt centralized feeding system, manipulator, mold monitor, with the transmission mechanism, etc., in order to improve the production efficiency and product quality, So as to enhance the competitiveness of enterprises, at the same time for enterprises to establish the image of modern factories, from "manufacturing" gradually to "intelligent manufacturing" change.

Key words: injection molding; Feeding system; Manipulator; Mold monitor

1  概述

注塑成型工艺是高分子材料制品加工中非常重要的成型工艺,所涉及的行业及领域甚广,如医疗、食品、化工、电子电器、仪器仪表。注塑成型必须借助注塑机和模具才能完成。注塑成型工艺原理是:将经加热处于熔融状态的高分子聚合材料以一定压力快速喷注入闭合的模具型腔内,再经冷却固化定型即得到成型制品的工艺过程。注塑成型适用于全部热塑性材料和部分热固性高分子材料,塑胶产品的大部分成品或零部件都是注塑成型制造的。注塑成型工艺的优点是制品花色多,制品尺寸精确,尺寸可由大到小,形状可以由简单到复杂、产品造型美观,通过更换模具产品容易更新换代,根据产品大小、产量需求估算,结合注塑机配置设计一模出数,操作可实现自动化,生产效率高、适合大批量高分子材料产品加工领域。……
