It includes a lower die body 5. The end of the power output shaft of the stamping device 3 is fixedly connected to the top surface of the upper die body 4. An inner cavity pipe installation groove 10 is opened inside the lower die body 5. A cavity pipe 11 is inserted on the surface of the cavity pipe installation groove 10. A return spring 12 is arranged inside the cavity pipe 11. The surface of the telescopic rod 9 is movably connected inside the cavity pipe 11. The surface of the telescopic rod 9 is movably connected to the through hole surface of the sealing ring 13. The surface of the sealing ring 13 is movably connected to the surface of the sealing ring storage groove 16. The sealing ring storage groove 16 is arranged on the top surface of the cavity pipe 11. The top surface of the telescopic rod 9 is fixedly connected to the bottom surface of the clamping block 17. The surface of the clamping block 17 is clamped to the groove surface of the mounting block 18. The top surface of the mounting block 18 is fixedly connected to the bottom surface of the unloading plate 7. The surface of the unloading plate 7 is movably connected to the surface of the unloading plate storage groove 8. The unloading plate storage groove 8 is arranged on the top surface of the die groove 6. By movably connecting the surface of the telescopic rod 9 to the through hole surface of the sealing ring 13 and movably connecting the surface of the telescopic rod 9 to the inside of the cavity pipe 11, and then arranging a return spring 12 on the surface of the cavity pipe 11, the telescopic rod 9 can contract up and down inside the cavity pipe 11 due to the elastic force of the return spring 12. The unloading plate 7 can be lifted and lowered by the contraction of the telescopic rod 9 inside the cavity pipe 11. Therefore, the die after stamping inside the die groove 6 can be lifted out by the lifting and lowering of the unloading plate 7, thus achieving the effect of stamping and die unloading.

[0022] Embodiment 2

[0023] Referring to the attached Figures 1 to 5 , on the basis of Embodiment 1, in order to realize that the stabilizing frame 2 plays a role in supporting and stabilizing the stamping device 3, the top surface of the stamping device 3 is fixedly connected to the inner bottom surface of the stabilizing frame 2. The bottom end of the stabilizing frame 2 is fixedly connected to the top surface of the base 1, and the stabilizing frame 2 is arranged in a "C" shape;

[0024] By fixedly connecting the top surface of the stamping device 3 to the inner top surface of the stabilizing frame 2, and then fixedly connecting the bottom end of the stabilizing frame 2 to the top surface of the base 1, the stabilizing frame 2 plays a role in supporting and stabilizing the stamping device 3.

[0025] Embodiment 3

[0026] See attached Figures 1 to 5 On the basis of the second embodiment, in order to realize the replacement and maintenance of the reset spring 12, the top surface of the cavity tube 11 is fixedly connected to the bottom end of the rotating shaft of the locking buckle 15, and the bottom surface of the locking buckle 15 is fixedly connected to the top surface of the rubber gasket 14, and the bottom surface of the rubber gasket 14 is closely attached to the top surface of the cavity tube 11.

[0027] By fixing the top surface of the rubber gasket 14 to the bottom surface of the locking buckle 15, and then fixing the end of the rotating shaft of the locking buckle 15 to the top surface of the cavity tube 11, when the knob locking buckle 15 is turned, the sealing ring 13 is locked inside the sealing ring receiving groove 16. When the reset spring 12 generates elastic thermal attenuation due to repeated pressing and rebounding, it needs to be replaced and maintained. Therefore, the cavity tube 11 can be removed from the inside of the cavity tube mounting groove 10, and then the reset spring 12 can be replaced and maintained.

[0028] In actual use, the surface of the telescopic rod 9 is movably connected to the through-hole surface of the sealing ring 13, and the surface of the telescopic rod 9 is movably connected to the inside of the cavity tube 11, and then a reset spring 12 is arranged on the surface of the cavity tube 11. The elastic force of the reset spring 12 allows the telescopic rod 9 to retract up and down in the cavity tube 11, and the material stripping tray 7 can be lifted up and down by the contraction of the telescopic rod 9 in the cavity tube 11. Therefore, the mold after stamping in the mold groove 6 can be pushed out by the lifting and lowering of the material stripping tray 7, so as to achieve the effect of stamping and demolding. By fixing the top surface of the stamping device 3 to the inner top surface of the stable frame 2 , and then fix the bottom end of the stabilizing frame 2 to the top surface of the base 1, so that the stabilizing frame 2 supports and stabilizes the punching device 3, and fixes the top surface of the rubber gasket 14 to the bottom surface of the locking buckle 15, and then fixes the end of the rotating shaft of the locking buckle 15 to the top surface of the cavity tube 11. When the knob locks the buckle 15, the sealing ring 13 is locked inside the sealing ring receiving groove 16. When the reset spring 12 is repeatedly pressed and rebounded to produce elastic thermal attenuation and needs to be replaced and maintained, the cavity tube 11 can be removed from the inside of the cavity tube mounting groove 10, and then the reset spring 12 can be replaced and maintained.
