The bottom of the installation block 320 fits against the top of the spinning workbench 100. When the installation block 320 slides back and forth with the hydraulic push rod 310, a certain frictional force is generated between its bottom and the spinning workbench 100, thereby ensuring the stability of the installation block 320 during the sliding process.

[0031] Combined Figures 1 - 3, A precision forming die for a hot spinning press under high pressure in this embodiment is used as follows: Place the original part to be processed on the mold core 260, start the first motor 210, the first motor 210 drives the first lead screw 220 to rotate, thereby driving the mold core 260 and the clamping rod 270 to approach each other, and then clamping and fixing the original part.
