摘　　要：针对皂盒上下盖组合型腔流动不平衡问题,使用塑料成型分析软件Moldflow对其进行了流动平衡优化分析。首先,对熔体在圆形管道中的流动机理进行分析。其次,使用三维建模软件Pro/e建立皂盒上盖和下盖的几何模型,并导入到塑料成型分析软件Moldflow中。在Moldflow中对皂盒上盖和下盖进行网格划分,并设计初始的浇注系统。对皂盒组合型腔的初始方案进行充填分析,发现了熔体在型腔内流道不平衡问题。最后,对皂盒组合型腔进行流动平衡优化分析,通过优化,熔体在模具型腔内流道时间不平衡率从14. 1%下降到1%,压力不平衡率从6. 68%下降到1. 58%,整个注射过程中型腔压力分布比较均匀。Aiming at the problem of flow unbalance in the combined cavity of the upper and lower cover of the soap box, the plastic balance analysis software Moldflow was used to optimize the flow balance. First, the flow mechanism of melt in a circular pipe was analyzed. Secondly, the 3D modeling software Pro/E was used to establish the geometric model of the top and lower cover of the soap box, and introduced into the plastic molding analysis software Moldflow. In Moldflow, the top and the lower cover of the soap box were meshed and the initial gating system was designed. Filling analysis of the initial scheme of the soap box combined cavity showed that the flow runner of the melt was not balanced in the mold cavity. Finally, the flow balance optimization analysis of the cavities was carried out. Through optimization, the time unbalance rate of the melt in the mold cavity decreases from 14. 1%to 1%, the pressure unbalance rate decreases from 6.68% to 1.58% , and the pressure distribution in the cavity is more uniform in the whole injection process.
