摘　　要：给出了判断熔体充模流动是否平衡的判据,并根据熔体充模流动的物理本质,构造了基于压力梯度的搜索方法来优化浇口位置,以实现熔体平衡充填模具型腔的目的。算例表明基于压力梯度的搜索方案简单有效。A criterion was given to judge whether the melt reached balance flow during mold filling procedure.Optimum gate location was decided based on pressure gradient search method which is constructed by the physical properties of melt flow during mold filling.Therefore the melt can fill the mold cavity evenly.Calculation example showed that the pressure gradient search method was simple and effective.
