摘　　要：当鼠标上下盖两个塑料件同时一模注塑成形时,容易产生填充不平衡等缺陷,为了获得良好的鼠标塑件质量,需要对其浇注系统进行优化。用MOLDFLOW先对鼠标的盖面网格进行划分,创建原始浇注系统,进行填充分析并显示结果,从而对原始浇注系统进行优化。通过多次迭代达到收敛要求后,浇口选用堆切式,并确定浇注系统各浇口的具体尺寸。通过优化后对流道进行平衡分析,结果显示充填时间和充填压力均可满足要求,从而说明MOLDFLOW模拟设计鼠标浇注系统可行。While the two plastic workpieces of upper and lower cover of computer mouse are formed in injection mold at the same time,defects such as unbalance filling would be produced usually,to achieve good quality plastic mouse,the pouring system should be optimized.Firstly,the mouse cover meshing will be done by MOLDFLOW to create origin pouring system.And then filling will be analyzed,which results will be indicated,thus the origin pouring system will be optimized.Through multiple iterations and satisfying the convergence demands,pile-cut style shall be selected for the pouring sprue,which specific dimension for each pouring system are determined.Pouring system is analyzed evenly after optimizing,which results show the filling time and pressure can satisfy the demands,thereby the Moldflow for simulating and designing the pouring system are feasible.
