【摘要】 以钢骨架塑料复合管管件-三通为例,运用Moldflow软件,对管件的注塑过程进行了模拟分析,研究了熔体的流动情况,使模具设计者可以直观了解塑料熔体在型腔中的流动状态.通过模拟分析,得出了填充时间、压力曲线、温度分布、熔接痕和气穴生成位置、剪切速率等参数,这些参数为后期模具的设计加工和制品成型参数的设定提供了理论参考,从而避免了模具设计的盲目性,降低了成本,缩短了模具开发应用周期.更多还原

【Abstract】 In this paper,the steel reinforced plastics pipe-T-joint tube was taken as an example,the processing of injection molding was simulated and analyzed with Moldflow software,then the melt flow was researched,so the designer of mold can intuitionisticly see the appearance of the melt flowing in the cavity.By simulating and analyzing,fill time,pressure curve,temperature distributing,weld lines,air traps,shear rate etc parameters were got.All these parameters will provide evidence for the design and machining of mold and setting of product in molding.So accordingly,the blindness of mold design is avoided,the cost is reduced and the exploit-apply period of mold is shortened.更多还原
