摘要
根据大孔出流理论 ,采用分配式直浇道系统 ,将阻流截面设置在浇口杯的出口处 ,使分配直浇道大于主直浇道截面的尺寸 ,每层内浇道截面尺寸等于直浇道截面尺寸 ,保证在充型过程中 ,分配直浇道不充满 ,同时控制浇注系统的形状和结构 ,改变金属液流动方向及造成不同的阻力 。
According to the large orifice discharge theory, we adopt the distributive sprue system, and put the chocked section in the entrance of pouring cup. Thus the size of distributive sprue system is large than that of the main one, the inner sprue size of every layer is equal to the sprue section size. During the filling process, by controlling the sprue’s sufficient degree, shape and structure, and changing the direction of metal liquid and resistance, the ordinal afflux of step type gating system are realized.
