A method for using a mold part processing and fixing device according to any one of claims 1 to 8, characterized in that: Here are the steps: S1: placing a metal part on a workbench (101); S2: starting a plurality of first motors (105), wherein the first motors (105) rotate the first threaded rods (106) to simultaneously move the plurality of first moving blocks (107) toward the center, so that the plurality of clamping plates (205) move together, and during the movement, the space between the plurality of clamping plates (205) is tightened, thereby pushing the metal parts to the center of the workbench (101); S3: starting the plurality of first electric push rods (202) so that the clamping plates (205) move further toward the center, and fixing the metal parts between the clamping plates (205) through the plurality of clamping plates (205); S4: Processing the fixed metal parts by other metal parts processing machines; S5: retracting the plurality of first electric push rods (202) so that the metal parts clamped by the clamping plate (205) are released, and starting the fourth motor (304) to rotate the turntable (306) via the second rotating shaft (305) so that the rotating table (301) rotates together, thereby rotating the metal parts on the rotating table (301); S6: starting the plurality of first electric push rods (202) again, so that the plurality of clamping plates (205) clamp the metal parts that have been rotated a certain number of degrees inside them again; S7: processing the fixed metal parts again by other metal parts processing machines; S8: retracting the plurality of first electric push rods (202) to make room, starting the second electric push rod (307) to raise the rotating platform (301), and lifting the metal part to a certain height, and simultaneously starting the second motor (113) to move the second moving block (201) upwards via the second threaded rod (110), so that the clamping plate (205) is also raised to the same height as the height of the metal part; S9: starting a pair of first electric push rods (202) at opposite positions to clamp the metal part via the clamping plate (205), retracting the second electric push rod (307) to lower the rotating platform (301) so that the metal part is suspended in the air, starting a pair of third motors (203) at opposite positions to rotate the clamping plate (205) via the first rotating shaft (204) so that the metal part fixed inside is flipped at a certain angle; S10: processing the fixed metal parts again by other metal parts processing machines; S11: starting a pair of third motors (203) in opposite positions, causing the metal part to flip and return to its original angle through the rotation of the first rotating shaft (204), starting the second electric push rod (307) to raise the rotating platform (301) again to catch the metal part, retracting the first electric push rod (202) to disconnect the clamping plate (205) from the metal part, and resetting the first moving block (107) through the first motor (105); S12: The rotating platform (301) is reset to its original height by means of the second electric push rod (307); S13: The processed metal parts are taken out from the rotating table (301).
