[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 6 As shown, this utility model provides a stamping die, including: a discharge structure 1, the discharge structure 1 including a base 11, a material collection groove 13, a shaft seat 14, a guide plate 15, a hinge seat 17, a drive motor 18 and a connecting rod 110, and the shaft seat 14 is provided with two sets; The lower mold structure 2 includes a fixed column 21, a fixed plate 22, a punching seat 25, a punching mechanism 26, a discharge chamber 27, a gas booster pump 28 and an air outlet pipe 210. The fixed column 21 is provided in four sets, and the four sets of fixed columns 21 are respectively fixedly connected to the four corners of the upper surface of the base 11. The upper mold structure 3 includes a mounting base 31, which is fixedly connected to the outer surface of the rear end of the base 11. A hydraulic cylinder 32 is mounted on the upper end of the front end surface of the mounting base 31, and an upper mold base 33 is mounted on the lower end of the hydraulic cylinder 32.

[0019] Among them, a limiting groove 12 is fixedly connected to the outer surface of the front end of the base 11, the material collection groove 13 is set inside the limiting groove 12, and two sets of shaft seats 14 are fixedly connected to the two ends of the upper surface of the base 11 respectively.

[0020] The position of the material collection groove 13 can be restricted by the limiting groove 12, which can prevent the material collection groove 13 from deviating from its position. Furthermore, the position of the material collection groove 13 is far away from the lower end of the lower mold structure 2, making it easier and safer for workers to remove it from the inside of the limiting groove 12.

[0021] The guide plate 15 has connecting shafts 16 fixedly connected to the outer surfaces of both ends, and the two sets of connecting shafts 16 are respectively connected to the interior of the two sets of bearing seats 14. The hinge seat 17 is fixedly connected to the outer surface of the rear end of the guide plate 15, and the position of the discharge port of the guide plate 15 corresponds to the position of the collection trough 13.

[0022] The guide plate 15 is inclined, so that the waste on its upper surface can slide through the discharge port of the guide plate 15 by its own gravity. The guide plate 15 can guide the waste into the collection tank 13, thereby preventing the waste from falling onto the upper surface of the base 11.

[0023] The drive motor 18 is mounted on the rear end of the upper surface of the base 11. An eccentric wheel 19 is fixedly connected to the output shaft of the drive motor 18. The lower end of the connecting rod 110 is connected to the eccentric wheel 19 by a bearing, and the upper end of the connecting rod 110 is connected to the hinge seat 17 by a bearing.

[0024] By starting the drive motor 18, the eccentric wheel 19 can be driven to rotate. When the eccentric wheel 19 rotates, it can drive the connecting rod 110 to swing up and down. During the swinging process, the connecting rod 110 will drive the guide plate 15 to swing back and forth around the center of the two sets of connecting shafts 16. When the guide plate 15 swings, it can prevent the waste from accumulating locally inside the guide plate 15. Furthermore, when the guide plate 15 swings, it can reduce the sliding friction resistance between the waste and its inner surface, thereby accelerating the waste discharge efficiency to a certain extent.

[0025] The four corners of the lower surface of the fixing plate 22 are fixedly connected to the upper ends of the four sets of fixing posts 21. The four corners of the upper surface of the fixing plate 22 are all fixedly connected to the guide posts 23. The upper surface of the fixing plate 22 is fixedly connected to the lower mold base 24. The punching seat 25 is fixedly connected to one end inside the lower mold base 24.

[0026] The four sets of fixed columns 21 can support the lower mold structure 2 as a whole, thereby improving the stability of the lower mold structure 2 during use.

[0027] The punching base 25 has punching holes on both sides of its inner surface. Two sets of punching mechanisms 26 are installed on both sides of the lower die base 24. The position and size of the front end of the two sets of punching mechanisms 26 are adapted to the position and size of the two sets of punching holes. The discharge cavity 27 is opened inside the punching base 25. The position of the discharge cavity 27 corresponds to the position of the two sets of punching holes.

[0028] By bringing the front ends of the two sets of punching mechanisms 26 close together, the parts can be punched. The waste generated during punching will enter the interior of the discharge cavity 27 as the front ends of the two sets of punching mechanisms 26 move. This design can prevent the waste from accumulating on the surface of the lower die base 24.

[0029] The fixed plate 22 has a discharge trough inside, which is connected to the discharge chamber 27. The gas booster pump 28 is installed on the lower surface of the fixed plate 22. The input end of the gas booster pump 28 is connected to the air inlet 29. The lower end of the air outlet pipe 210 is connected to the output end of the gas booster pump 28. The upper end of the air outlet pipe 210 is fixedly connected to the inside of the discharge chamber 27. The position of the air outlet of the air outlet pipe 210 corresponds to the position of the front end of the two sets of punching mechanisms 26.

[0030] The gas booster pump 28 can be connected to an external air source through the air inlet 29. After the gas enters the gas booster pump 28, the gas booster pump 28 can convert it into high-pressure gas, and then blow it out through the air outlet 210. At this time, the high-pressure gas can impact the front end of the two sets of punching mechanisms 26, thereby preventing the waste material from sticking together, so that the waste material can fall into the discharge trough through the discharge chamber 27.

[0031] The upper mold base 33 is positioned corresponding to the lower mold base 24. Guide sleeves are provided inside the four corners of the upper mold base 33, and the four sets of guide sleeves are respectively sleeved on the outer surfaces of the four sets of guide posts 23.

[0032] By activating the hydraulic cylinder 32, the upper die holder 33 can be pushed downward. The stability of the upper die holder 33 during movement can be improved by the cooperation of the four sets of guide sleeves and guide pillars 23. When the upper die holder 33 and the lower die holder 24 are in contact, the parts can be stamped.

[0033] The working principle and usage process of this utility model are as follows: First, the part to be processed is transported into the punching seat 25 on the lower die base 24 of the lower die structure 2 via the transport structure. Then, the hydraulic cylinder 32 of the upper die structure 3 is activated, driving the upper die base 33 to press down along the guide post 23 on the fixed plate 22 of the lower die structure 2, fitting against the lower die base 24 to punch the part. Next, the punched part moves on the upper surface of the punching seat 25 between the two sets of punching mechanisms 26. Then, the punching mechanisms 26 on both sides of the lower die base 24 are activated, causing their front ends to approach the part passing through the punching seat 25. The punching hole punches holes in the parts, and the waste generated by punching is pushed into the discharge chamber 27 in the punching seat 25. At the same time, the gas booster pump 28 blows high-pressure gas through the air outlet pipe 210 to the front end of the punching mechanism 26 to prevent the waste from sticking. The waste enters the discharge groove of the fixed plate 22 through the discharge chamber 27 and falls into the interior of the guide plate 15. Then, the drive motor 18 on the base 11 is started, which drives the eccentric wheel 19 to rotate. Through the connecting rod 110, the guide plate 15 is driven to swing back and forth, moving the waste to the discharge port of the guide plate 15 and finally falling into the collection trough 13.
