In order to facilitate the ejection of stamped parts and scraps, the telescopic rod 12 is contracted before stamping, thereby driving the bottom of the connecting plate 21 and the top surface of the positioning plate 13 to fit together. The connecting plate 21 drives the sliding cylinder 23 to slide downward in the positioning plate 13, the compression spring 24 is compressed, and the stamping die is placed in the placement slot 16. After the stamping is completed, the restoring elastic force generated by the squeezed compression spring 24 and the elongation of the telescopic rod 12 jointly push the sliding cylinder 23, the connecting plate 21 and the pad 22 to move upward, thereby realizing the pop-up function.

[0017] The movable device 2 includes a connecting plate 21, and the outer wall at the top of the connecting plate 21 is fixedly connected to a pad 22. Connecting holes 25 are opened in the walls of the connecting plate 21 and the walls of the pad 22. A sliding cylinder 23 is fixedly connected to the side of the connecting plate 21 away from the pad 22. A compression spring 24 is fixedly connected to the inner wall of the sliding cylinder 23. The end of the compression spring 24 away from the sliding cylinder 23 is fixedly connected to the outer wall at the top of the base 11. The outer wall of the sliding cylinder 23 is slidably connected to the inner wall of the positioning plate 13. During the process of removing the workpiece, the gas flows through the support block 15 and enters the ventilation groove 14. The ventilation groove 14 on the positioning plate 13 maintains the air pressure balance of the workpiece position through the connecting hole 25, which can effectively prevent the workpiece from being adsorbed on the punch press due to local air pressure changes during the stamping process, ensuring that the workpiece can be smoothly ejected by the ejection device after the stamping is completed.

[0018] The mold removal device 3 includes a force block 31, the outer wall of the force block 31 is fixedly connected to a connecting rod 32, the end of the connecting rod 32 away from the force block 31 is fixedly connected to a pushing block 33, the outer wall of the pushing block 33 is symmetrically fixedly connected to a limiting column 34, and the side of the pushing block 33 away from the limiting column 34 is fixedly connected to a scooping bar 35, the outer wall of the connecting rod 32 is slidably connected to the inner wall of the positioning plate 13, the outer wall of the limiting column 34 is slidably connected to the inner wall of the positioning plate 13, the outer wall of the bottom of the pushing block 33 and the outer wall of the bottom of the scooping bar 35 are both slidably connected to the outer wall of the top of the base 11, the operator applies force to the connecting rod 32 through the force block 31, the force block 31 makes the connecting rod 32 drive the pushing block 33 to move, the limiting columns 34 on both sides of the pushing block 33 slide in the positioning plate 13 to ensure the stability of the movement of the pushing block 33, and when the pushing block 33 moves, it will drive the scooping bar 35 to move, thereby lifting the mold.

[0019] Working principle:

[0020] When the die parts are punched, the pressure of the punch press acts on the pad 22 and the connecting plate 21. In order to facilitate the ejection of the stamped parts and scraps, the telescopic rod 12 is retracted before punching, thereby driving the bottom of the connecting plate 21 and the top surface of the positioning plate 13 to fit together. The connecting plate 21 drives the sliding cylinder 23 to slide downward in the positioning plate 13, the compression spring 24 is compressed, and the stamping die is placed in the placement groove 16. After the stamping is completed, the restoring elastic force generated by the squeezed compression spring 24 and the extension of the telescopic rod 12 jointly push the sliding cylinder 23, the connecting plate 21 and the pad 22 to move upward to realize the ejection function, and the extension rod 12 on the base 11 The retracted rod 12 and the relative sliding between the sliding cylinder 23 and the positioning plate 13 all provide certain support and guiding effects for the supporting device 1 and the movable device 2. During the process of removing the workpiece, the gas flows through the supporting block 15 into the ventilation groove 14. The ventilation groove 14 on the positioning plate 13 maintains the air pressure balance of the workpiece position through the connecting hole 25, which can effectively prevent the workpiece from being adsorbed on the punch press due to local air pressure changes during the stamping process, ensure that the workpiece can be smoothly ejected by the ejection device after the stamping is completed, improve the unloading efficiency, and reduce the difficulty and potential damage of the workpiece removed due to adsorption, ensure the surface quality of the workpiece, and help maintain the continuity of the production process.

[0021] When the stamping is completed and the mold needs to be removed, a mold removal device 3 is provided to facilitate the mold removal operation. The operator applies force to the connecting rod 32 through the force block 31. The force block 31 causes the connecting rod 32 to drive the pushing block 33 to move. The limiting columns 34 on both sides of the pushing block 33 slide in the positioning plate 13 to ensure the stability of the movement of the pushing block 33. When the pushing block 33 moves, it will drive the scooping bar 35 to move. The mold removal devices 3 on both sides move at the same time, and at the same time drive the scooping bar 35 close to the mold. The inclined surface setting of the scooping bar 35 will lift the mold after the stamping is completed, thereby facilitating the operator to remove the mold parts.

[0022] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
