[0031] Embodiment 2

[0032] On the basis of the first embodiment, a support seat 5 is fixed at the lower end of the lower die 4, and the support seat 5 is provided with two groups, and the two groups of support seats 5 are respectively located at the two ends of the lower surface of the lower die 4, the driving motor 7 is installed on the base 6, and the base 6 is arranged beside the lower die 4, the transmission rod 8 is connected to the lower die 4 through a bearing, and the linear bearing rod 15 is fixedly connected to the lower die 4. The surface of the lower die 4 is provided with a sealing plate 3, and the sealing plate 3 is fixedly connected to the lower die 4 through a hexagonal bolt 2;

[0033] When in use, by starting the driving motor 7, the output end of the driving motor 7 drives the transmission rod 8 to rotate, and a partition block 14 is fixed on the transmission rod 8. The two sides of the partition block 14 are respectively provided with a first external thread 12 and a second external thread 16, and the thread rotation directions of the two external threads are opposite.

As the first side plate 11 and the second side plate 17 approach each other, the first spring 13 and the second spring 18 are squeezed. Since the first slider 10 and the second slider 19 are both slidably connected to the linear bearing rod 15 and are both hinged to the hinge plate 23, this squeezing action will push the first slider 10 and the second slider 19 to approach each other along the linear bearing rod 15. Then, the hinge plate 23 is subjected to the first spring 13 and the second spring 18 are squeezed. After the joint force of a slider 10 and a second slider 19, the cross plate 20 hinged at the other end is pulled upward, and the moving rod 21 fixed at the upper end of the cross plate 20 is slidably connected to the stamping frame 1. Therefore, the upward movement of the cross plate 20 will drive the moving rod 21 to rise synchronously. A push plate 24 is fixed to the upper end of the moving rod 21.

This process realizes the rapid demoulding of the stamped metallurgical parts, ensures that the parts are not damaged, and effectively reduces the loss of parts. In this way, it is avoided that when the metallurgical products are taken out after stamping, the removal process is relatively cumbersome, so that a large number of parts are easily damaged when they are taken out, thereby making the parts scrapped, thereby causing the problem of waste of resources.
