摘　　要：以电脑面板的塑料注射模具为例,通过对三种浇注系统设计方案的充模过程的流动模拟分析,得到了各方案的充模时间、温度、剪切速率、熔接线及气穴、注射压力和锁模力分布图。经过比较分析,得出了最佳的设计方案,并提前发现了可能出现的成型缺陷,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 computer panel for example, through the flow simulation and analysis of the filling mould process for three gating system design programs, it got each program＇s filling time, temperature, shearing rate, melting wiring and air pocket, injecting pressure and the distribution map of locking strength. Through comparing and analyzing, the relatively good program was designed, and the shaping defect that may appear ahead of time was found, which improved the success rate of once-testing mould so as to realize shorten mould design cycle and reduce mould manufacturing cost.
