1、摘 要随着塑料制品在生产生活中应用的增多,塑件制造得到较高的重视。因为注塑模具在生产塑料件的速率和质量上有较大的优越性,所以在塑料制品的成型中占有很大比重,因而塑料模具的设计显得至关重要。本设计主要是斜三通管的注射模具设计。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。介绍了斜三通管注塑模具的结构组成及工作原理。该模具一模一腔,采用斜导柱和侧滑块抽芯机构,结构合理,运行可靠。通过模具设计表明该模具能达到斜三通管的质量和加工工艺要求。目的是通过对该零件的注塑模工艺的设计,了解注
2、塑模具的设计步骤,ABS 等材料的各项性能指标,工艺方案的选择,和侧向抽芯技术的掌握。塑料注射的设计过程,其中的设计内容有零件的工艺性编制:塑件的工艺性分析、塑件的体积和质量计算及注射机参数的确定;结构设计:分型面选择、型腔数确定、型腔的排列方式、浇口设计、侧向分型抽芯机构设计、推出及复位机构方式确定;型芯、型腔尺寸计算;模具加热和冷却系统计算;模具闭合高度确定;注射机有关参数的校核;如此设计出的结构可确保模具工作运用可靠。最后对模具结构与注射机的匹配进行了校核。并用autoCAD绘制了一套模具装配图和零件图。关键词: 斜三通;注塑模具;注射机;侧型芯滑块;斜导柱AbstractWith th
