[0032] Working principle: When in use, when installing the lower mold 6, align the lower mold 6 with the edge of the slot 7 and press the lower mold 6 downward, so that the positioning rod 8 is inserted into the inner wall of the lower mold 6 to complete the initial installation, and then rotate the threaded rod 12. Through the action of the thread, the threaded rod 12 will also make a linear motion when rotating, thereby driving the control board 13 to move. The movement of the control board 13 drives the slider 10 to move through the cooperation with the control slot 14. The movement of the slider 10 drives the extrusion block 11 and the surface of the lower mold 6 to fit and extrude the lower mold 6. The extrusion block 11 is set at an angle so that the extrusion block 11 fixes and clamps the lower mold 6, and the lower mold 6 is subjected to a downward component force, thereby pressing the lower mold 6 tightly into the inside of the slot 7.

[0033] The stamping waste generated during the production of automobile sheet metal parts will slide into the interior of the collection box 16 through the inclined discharge chute 15 to avoid waste accumulation affecting the progress of work. During this process, the power supply of the drive motor 17 can be started through the controller 2, and the drive motor 17 drives the main shaft 18 to rotate. The rotation of the main shaft 18 causes the shaft 19 to rotate in the opposite direction through the cooperation of gear 1 21 and gear 2 22, thereby causing the sweeping plate 20 to rotate, thereby sweeping the waste that does not have time to slide on the discharge chute 15 into the interior of the collection box 16, avoiding too much waste that does not have time to slide and accumulates on the discharge chute 15, which is beneficial to the progress of work.
