摘　　要：本文将注塑系统平衡的理论和数值模拟技术紧密结合起来,研究鼠标组合型腔的浇注系统。如果熔体不能同时到达各浇口并充满各个型腔,将导致压力分布不均匀,使制品的质量下降,以至于出现充不满等问题,本研究对浇注系统优化,得出了一组最佳的浇注系统方案,从而保证熔体能够基本上在同一时间充满型腔,实现熔体的平衡流动。从分析结果可知,要平衡熔体在组合型腔内的流动,分流道的截面形状和尺寸起到非常大的作用。This paper closely combines the injection system balance theory and the numerical simulation technique, as for the asymmetric two cavities of the mouse, if the plastic melt cannot reach each gate and fulfill each cavity in the same time, it will cause the heterogeneity of the pressure arrangement, which could lead to bad quality, or short shot to optimize the injection system, guarantee the melt can be able basically filling cavity in the same time, and realize the melt balance flow. From the analysis result, divides the flow channel the section shape and the size play a key role in balance melts in combination cavity flowing.
