Aiming at the thin-wall large-scale plastic part of dual-tub of washing machine,the whole filling process of plastic injection wsa simulated by utilizing Pro/Plastic Advisor.The quantity and location of gate were identified and runner size was computed according to theoretical model.The three-dimensional(3D)design of hot runner gating system was proceeded by Pro/E software and the splice of mold cavity of movable mold and fixed mold and insert design were proceeded according to the requirements of parting of plastic part and mold process,whold 3D assembly design of plastic injection mold was achieved by utilizing standard parts that EMX provided.The three links development of product design,mold design and mold manufacture were realizde smoothly by parametrical modeling technology of Pro/E.The size and shape of plastic part conformed the request when the mold was put into production.%针对洗衣机双缸薄壁大型塑料件,利用Pro/Plastic Advisor进行充型模拟,确定最佳进胶点数量与位置,按照理论模型进行了流道尺寸计算.基于Pro/E软件,进行三维热流道浇注系统设计,根据塑料件分型与模具加工工艺的要求,进行动、定模模腔的拼接、镶件设计,利用EMX提供的标准件完成模具全三维装配设计.通过Pro/E参数化建模技术,实现产品设计、模具设计和模具制造三个环节的开发.模具投产后,塑料件尺寸、形位符合要求.
