高温合金空心叶片制造过程中的型芯固定结构
By drilling positioning holes in the high-temperature alloy hollow blade wax mold and using platinum wire as a core support, the problems of difficult-to-control insertion angle and the influence of wax mold thickness were solved, achieving high-precision support effect and stability.

AI Technical Summary
In the current manufacturing process of high-temperature alloy hollow blades, it is difficult to precisely control the insertion angle of the metal core support, which is prone to skewing, and the thickness of the wax mold affects the stability and support effect of the core support.
Positioning holes are drilled on the blade wax model. The diameter of the core support is slightly larger than that of the positioning hole. The ceramic core is precisely inserted through the positioning hole, and platinum wire is used as the core support material.
It improves the accuracy of wire insertion, reduces the difficulty of operation, ensures the stability and support effect of the core support, reduces the amount of wax extrusion, and reduces the formation of voids.
