摘要
塑料注射模具是成型塑料的一种重要工艺装备,通过对液压管路三通塑料模具设计,能够全面的了解塑料模具设计的基本原则、方法.并能较为熟练的使用Proe4.0、AUTOCAD软件进行塑料模具设计,提高自己的绘图能力。为今后从事设计工作打下了坚实的基矗
随着现代工业发展的需要,塑料制品在工业、农业、日常生活和军事等各个领域的应用范围越来越广,质量要求也越来越高,中国已经成为全球最大的塑料市场之一,塑料制品产量全球第二。为了做到高质、高效、低成本,从而提高市场占有率,注塑模具的开发、设计、加工与CAD/CAE/CAM技术相结合具有重大意义。
本次主要设计是对液压管路三通注射模的设计,重点对塑件的成型原理、原料选用和注射技术进行分析。通过根据形状、尺寸、精度及表面质量要求的分析结果,确定所需的模塑成型方案,制品的后加工、分型面的选择、型腔的数目和排列、成型零件的结构、浇注系统等。
关键词:注塑模;模具结构;侧型芯;工艺方案
