压铸填充过程的理论探讨

Discussion on the Theory of Mold Filling Process in Die Casting

对在同一个压铸件上造成品质差异的原因进行了探讨分析。指出 :这是由于存在填充过程的两个区域 ,即主干型腔和非主干型腔 ,这二个区域填充状况是不一样的 ,只有顺应这个规律 ,搞好压铸模设计 ,特别是浇注系统的设计 ,才是提高压铸产品品质的根本途径。

Reason of quality difference for the same die casting was analyzed. It is indicated that there exist two areas in mold filling process, namely, primary trunk die cavity and non primary trunk die cavity. The two areas are different in filling quality. The radical ways to improve die casting quality are conformable to the law with respect to die casting die design,especially the gating system design.
