[0025] The transmission mechanism comprises a rack 8 mounted on the matching rod 7, and the screw rod 10 is provided with a gear 11 meshing with the rack 8. When the matching rod 7 is lifted in the matching slot 5, the gear 11 can be meshed with the rack 8, so as to drive the screw rod 10 to rotate. It should be noted that only the part of the screw rod 10 in the rotating chamber 9 is provided with a screw thread on the outer wall.

[0026] The first elastic mechanism comprises a first spring 20 arranged in the connecting slot 19, and the two ends of the first spring 20 are connected with the outer wall of the matching frame 6 and the inner wall of the connecting slot 19 respectively. The first spring 20 and the connecting slot 19 can realize the continuous lowering operation of the matching frame 6 and the upper die 4 when the matching rod 7 is at the bottom of the matching slot 5.

[0027] The connecting mechanism comprises a connecting frame 17 sleeved on the screw rod 10, and the connecting frame 17 is fixedly connected with the piston plate 16. The connecting frame 17 is in U-shaped design, and the horizontal part of the connecting frame 17 is slidably arranged through the inner wall of the rotating chamber 9 and extends into the movable chamber 15. In this way, the connecting frame 17 has a self-limited position, so that the connecting frame 17 will not rotate with the screw rod 10.

[0028] The second elastic mechanism comprises a second spring 14 arranged in the movable groove 12, and the two ends of the second spring 14 are connected with the inner wall of the movable groove 12 and the outer wall of the material pushing block 13 respectively.

At this time, the first spring 20 is compressed, and the matching frame 6 enters the connecting groove 19.

[0031] After the stamping is completed, the hydraulic cylinder 3 is contracted to drive the upper die 4 to rise. At this time, the matching frame 6 rises first and the matching rod 7 does not rise. At this time, the first spring 20 is reset, and as the upper die 4 and other components continue to rise, the first spring 20 is reset. Then, the matching rod 7 and the rack 8 rise, the screw rod 10 reverses, the connecting frame 17 drives the piston plate 16 to move and reset, the air in the movable chamber 15 is sent into the movable groove 12, the second spring 14 is stretched, and the material pushing block 13 is extended to push out the formed material, so as to facilitate the unloading operation.
