摘要

叶轮有8个叶片

叶片为薄且面积大的曲面

叶轮的轮毂对模具型芯包紧力较大

若推出机构不合理

容易引起工件变形甚至断裂

故采用8个摆块与1个推管的组合推件机构。分析了铸件的工艺性

论述了模具结构和工作过程。

Abstract

There are 8 blades on an impellers

and the blades possess thin and large curved surface.Meanwhile

wheel of impellers exhibits a bigger wrapped force to the mould core.Unreasonable ejector design can result in the deformation or crack of the impeller.So 8 swing blocks and an ejector sleeve are adopted in push-out mechanism.The casting technology was analyzed

and mould structure and the operation process were described.
