Embodiment Construction
[0016] 1. Mold design:
[0017] Considering the special structure of the cooling channel, the gas pressure cannot complete the molding at one time, so the water-soluble core needs to be designed. After the first molding is completed, the water-soluble core is dissolved with water, and then the secondary molding is performed to achieve the final design.
[0018] 2. Mold manufacturing
[0019] Use a high-pressure water cutting machine to accurately cut the unfolded material (the accuracy of the high-pressure water cutting machine produced by the American PA company is ±0.05), after pickling and drying, apply solder resist, and dry it for the second time. Stack 4 layers of titanium alloy plates with different thicknesses and weld process edges, inlet and outlet nozzles.
[0020] 3. Manufacture of core
[0021] Water-soluble materials are selected, and their profiles are processed by CNC machine tools, which meet the design requirements
