摘　　要：本文不袭用传统大型注塑模浇注系统调计定剪切速率计算截面尺寸等观点，在聚合物幂律模型基础上，通过合理分配压力降，采用解析法导出了新的流道截面尺寸优化设计模型。采用该方法对桑塔纳轿车前保险杠注射模浇注系统进行优化设计后，在保证熔体充模的情况下，流道截面有较大的减小。Contrary to some traditional views about the runner design of injection mold,a optimum runner design method,based on power law and the reasonable attribution of pressure drop,was proposed in this paper.Using C MOLD software for injection molding CAE,it has been proved that the radius of runner which was calculated by the new method can be reduced obviously.
