带预复位机构的推管和摆块推件的叶轮压铸模
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.
