The fixed block 705 moves into the fixed groove 704 under the elastic force of the first spring 706, and is used to fix the moving seat 702. The interior of the moving seat 702 is located on the upper side of the first spring 706 and is rotatably connected to a spur gear 707, and the interior of the moving seat 702 is located on the upper side of the spur gear 707 and is slidably connected to a slider 708, which extends out of the moving seat 702 and is located above the support plate 703, and the slider 708 can drive the fixed block 705 to move through the spur gear 707.

[0042] The interior of the movable seat 702 is located above the slider 708 and is slidably connected to an extrusion block 709. One end of the extrusion block 709 extends out of the movable seat 702 and is located above the support plate 703. A second spring 710 is connected between the extrusion block 709 and the movable seat 702. The interior of the movable seat 702 is located on the upper side of the extrusion block 709 and is slidably connected to a lower pressure frame 711. The top of the lower pressure frame 711 extends to above the movable seat 702.

[0043] When the steel part is stamped, the steel part is placed in the placement groove 9. At this time, the movable seat 702 is located at the top of the movable groove 701. The lower pressure frame 711 squeezes the squeezing block 709 so that the squeezing block 709 moves to the inside of the movable seat 702. The second spring 710 is in a squeezed state. The fixed block 705 enters the fixed groove 704 under the elastic force of the first spring 706 to fix the movable seat 702. When the steel part is die-cast, the stamping drive mechanism drives the upper mold 4 to move downward. The upper mold 4 moves downward and contacts the slider 708, pushing the slider 708 to move. The slider 708 The movement drives the spur gear 707 to rotate, and the rotation of the spur gear 707 drives the fixed block 705 to move, causing the first spring 706 to be squeezed, and the fixed block 705 moves out of the fixed groove 704 to cancel the fixation of the movable seat 702, and the upper mold 4 continues to move and contact with the movable seat 6, pushing the movable seat 6 to move downward, and the upper mold 4 and the fixed seat 5 squeeze the steel part to deform, and the movable seat 6 moves downward through the support plate 703 to drive the movable seat 702 to move downward. At this time, the lower pressure frame 711 is separated from the top of the movable groove 701, and the squeezing block 709 is moved out of the movable seat 702 by the elastic force of the second spring 710;

[0044] When the die-casting is completed, the stamping drive mechanism drives the upper mold 4 to move upward, and the upper mold 4 moves and contacts the outer wall of the extrusion block 709, and the moving seat 702 is pushed upward by the extrusion block 709. The moving seat 702 moves upward and drives the movable seat 6 to move upward through the support plate 703, thereby pushing the steel part to move upward to prevent the steel part from being pressed tightly against the lower mold, until the moving seat 702 moves to the top of the moving groove 701, and the lower pressure frame 711 contacts the top of the moving groove 701. The lower pressure frame 711 is forced to move and push the extrusion block 709 to move into the inside of the moving seat 702. The extrusion block 709 is separated from the upper mold 4, and the upper mold 4 no longer drives the moving seat 702 to move. At the same time, the fixed block 705 is moved into the fixed groove 704 by the elastic force of the first spring 706 to fix the moving seat 702.

[0045] When the upper mold 4 moves downward, the rotating plate 807 enters the inner cavity of the vertical groove 802, and the bottom end of the extrusion rod 803 contacts the rotating plate 807, pushing the rotating plate 807 to rotate. When the extrusion rod 803 separates from the rotating plate 807, the rotating plate 807 is reset by the elastic force of the fourth spring 808; when the upper mold 4 moves upward, the rotating plate 807 enters the inner cavity of the vertical groove 802.
