摘　　要：以家用吊灯塑料灯罩注射模具为例,通过对充模过程的流动模拟分析,得到了注射压力、气穴、熔接线、充模时间、温度、剪切应力及锁模力分布图。经过模拟分析,提前发现了可能出现的塑件成型缺陷,提高了塑料注射模具一次试模的成功率,实现了缩短模具设计周期,降低模具制造成本的目的。Taking the plastic injection mould of the plastic lampshade for example,through the flow simulation and analysis of the filling mould process,it got the injection pressure,air pocket,melting wiring,filling time,temperature,shearing rate and the distribution map of locking strength.Through comparing and analyzing,the paper drew the relatively good design program,and found the shaping defect that may appear ahead of time,which improved the success rate of once-testing mould so as to realize shorten mould design cycle and reduce mould manufacturing cost.
