Embodiment Construction
[0035] Such as Figure 1~3 As shown, a method for positioning the ceramic core of a turbine blade with integrally cast cover plate structure includes positioning the ceramic core of a turbine blade with integrally cast cover plate structure in the blade shape mold and positioning the ceramic core in the blade wax model in the ceramic mold. Two processes are located in the shell;
[0036] The positioning process of the ceramic core in the blade shape mold includes the following steps:
[0037] Step 1: Open the blade shape mold, and place the ceramic core in the cavity of the blade shape mold;
[0038] Step 2: The positioning of the ceramic core in the left and right direction in the blade shape mold: the left and right direction refers to the direction of the blade exhaust side, and the positioning bump of the blade shape mold is put into the blade tip on the ceramic core for positioning In the groove 1, insert the positioning protrusion 2 of the blade shape mold into the ten...
