| 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. |
