This article conducts a three-dimensional numerical simulation analysis on the casting structure of a complex pot shaped embedded titanium blade,and designs and verifies two casting schemes for the pot shaped embedded titanium impeller with an area of about three-fifths and a wall thickness of less than 3mm.The final conclusion is that the new machined graphite composite mold has excellent casting filling and blade shape retention ability to the complex structure of pot shaped embedded titanium blades during casting.but its surface quality is significantly improved compared to traditional machining graphite mold casting,which can be applied in practical production.
