基于UG的直三通管注塑模具设计 DESIGN OF INJECTION MOLDING TOOL FOR STRAIGHT THREE PIPE BASED ON UG 摘要 当前，树脂工业产品已然走进人们日常的生产和生活中。跟随着工业树脂产品和家庭树脂产品的品系和供求量逐日显着增加，这部分产品升级的周期越发短，因而对材料的品系、产量及质量都给出了比以往更高的要求。从而使对树脂模具的开发设计与加工的能力也需要越发高。在当今塑料成形制造中，树脂产品的品质与塑料成形模具、塑料成形设备和树脂加工工艺这几个因数紧密联系。就这三项要点中，塑料成形模具品质最为重要的，优质模具最能大幅度提升塑料成形产品制造水平以及综合效益，优质模具能保证塑件的外形、性能、品质等等。 这篇文稿有关内容是对塑胶模具的型腔布局、流道系统、引导装置、顶出装置、导气系统及调温系统等开展具体的剖析、精确求算及详细设计。在设计步骤中，本文综合考虑注塑收缩变形、温度因子、推出力等注塑模具因子的影响，让设计好的模具能够达到综合的设计条件，满足实际工程的需要。 关键词注塑成型；浇注系统；CAD绘图 Abstract At prese
