Abstract
As one of the main contents of die structure design, cavity design for investment casting die of turbine blade consists the following steps: (1) Design the blank model by adding machining allowance on the part model of turbine blade. (2) Design the process model by adding process structure on the blank model. (3) Design the cavity model by considering the shrinkage of wax and alloy. (4) Design the block of cavity model. (5) Establish the parting directions and parting lines based on the structural feature of cavity model. (6) Design the parting surfaces and generate die pieces. The design flow is shown in Fig. 3.1.
