All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figures 1-4 The utility model provides a technical solution: a high-efficiency stamping die for easy demoulding of sheet metal parts, comprising: a controller 1, a cylinder 2 is installed on the lower side of the controller 1, a sliding die 3 is fixedly connected to the output end of the cylinder 2, a punch 4 is fixedly connected to the bottom of the sliding die 3, a stripping plate 5 is arranged on the lower side of the punch 4, the lower side of the stripping plate 5 is fixedly connected to one end of a buffer 6, the other end of the buffer 6 is fixedly connected to a receiving plate 7, and a punching seat 8 is arranged on the lower side of the receiving plate 7.

[0025] The controller 1 is electrically connected to the cylinder 2, and the steel strip to be punched passes through the steel strip groove 11. The output end of the cylinder 2 is extended by starting the controller 1, thereby driving the sliding die 3 to move, and the sliding die 3 drives the punch 4 to punch into the circular hole of the punching seat 8. During this process, the receiving plate 7 is placed on one side of the punch 4. After the punch 4 punches into the punching seat 8, the steel strip is punched out of the annular gasket and a piece of circular waste is generated. During the reverse movement of the cylinder 2, the receiving plate 7 moves in the direction close to the punch 4, so that one end of the stripping plate 5 contacts the bottom end of the punch 4, and the gasket adhering to the bottom end of the punch 4 is squeezed out by the scraping of the stripping plate 5. In this process, the stripping plate 5 is buffered by the buffer 6 to avoid damage to the punch 4, and finally the gasket falls into the receiving plate 7, which can effectively separate the gasket products.

[0026] Embodiment 2: On the basis of embodiment 1, the controller 1 is fixedly connected to the upper surface of the top plate 9, the cylinder 2 is fixedly connected to the lower surface of the top plate 9, and the two sides of the top plate 9 are fixedly connected to the fixed plate 10, so that the cylinder 2 and the controller 1 are fixed through the top plate 9, and the two sides of the top plate 9 are fixedly connected with the fixed plates 10, and the bottom of the fixed plate 10 is provided with a steel belt groove 11, and a limiting plate 12 is arranged on one side of the steel belt groove 11. The steel belt groove 11 opened at the bottom of the fixed plate 10 is convenient for the steel belt to pass through, and the limiting plate 12 is fixedly connected between the fixed plates 10, and a limiting block 13 is arranged on the upper side of the limiting plate 12, and a sliding block 14 is slidably connected in the limiting block 13, and the sliding block 14 is fixedly connected to the sliding mold 3, and the limiting plate 12 fixedly connected between the two fixed plates 10 limits the steel belt, thereby improving the stamping accuracy, and the limiting block 13 limits the sliding block 14, so that the sliding block 14 limits the sliding mold 3.

[0027] The output end of the cylinder 2 is extended by the controller 1, thereby driving the movement of the sliding die 3. The sliding die 3 drives the sliding block 14 to slide under the limitation of the limiting block 13, so that the sliding die 3 slides more stably through the limitation of the limiting block 13, thereby improving the punching accuracy. The steel strip to be punched passes through the steel strip groove 11, and the steel strip is preliminarily limited by the steel strip groove 11, and then the steel strip is limited by the limiting plate 12 to further improve the punching accuracy.

[0028] Embodiment 3: On the basis of Embodiment 2, one side of the lower surface of the sliding block 14 is fixedly connected with a base 15. One side of the base 15 is provided with a side seat 16. One side of the side seat 16 is fixedly connected with the limiting block 13. The base 15 is fixedly installed on one side of the lower surface of the sliding block 14, and the side seat 16 is fixedly installed on one side of one of the limiting blocks 13. One end of the base 15 is rotatably connected with one end of the sleeve rod 17 through a pin shaft 18. The other end of the sleeve rod 17 is rotatably sleeved with a double-headed stud 19. Both ends of the double-headed stud 19 penetrate through the material receiving plate 7 and are fixedly sleeved in the lower connecting rod 20. The sleeve rod 17 is used for the transmission between the sliding block 14 and the base 15. One end of the sleeve rod 17 is rotatably sleeved with a double-headed stud 19. Both ends of the double-headed stud 19 are sleeved in the lower connecting rod 20 and are threadedly connected with nuts to limit the double-headed stud 19. One end of the lower connecting rod 20 is fixedly connected with the material receiving plate 7 through a pin shaft 18. The other end of the lower connecting rod 20 is fixedly connected with one end of the upper connecting rod 21. The other end of the upper connecting rod 21 is rotatably connected with the side seat 16 through a pin shaft 18. The lower surface of the punching seat 8 is fixedly connected with the bottom plate 22. One end of the upper connecting rod 21 is fixedly connected with the lower connecting rod 20. The other end of the upper connecting rod 21 is rotatably connected with the side seat 16 through a pin shaft 18.

[0029] During the process of the punch 4 punching into the round hole of the punching seat 8, under the connection action of the sleeve rod 17, one end of the sleeve rod 17 is rotatably connected to the base 15 through a pin shaft 18. Thus, the sleeve rod 17 drives the stud 19 rotatably sleeved at the other end to move away from the punching seat 8. At the same time, one end of the upper connecting rod 21 is rotatably connected to the side seat 16 through a pin shaft 18, and the other end of the upper connecting rod 21 drives the lower connecting rod 20 to move. Furthermore, the lower connecting rod 20 is fixedly connected to the material receiving plate 7 through a pin shaft 18, so that it drives the material receiving plate 7 to rotate away from the punching seat 8, thus making the material receiving plate 7 vacate the stamping space. Then, with the cooperation of the punch 4 and the punching seat 8, a ring-shaped gasket is punched out from the steel strip, and a circular waste piece is generated. At this time, the cylinder 2 contracts. While the cylinder 2 contracts, it drives the sliding block 14 to slide upward. Thus, the sleeve rod 17, through its connection with the stud 19, pulls the material receiving plate 7 to move downward to the lower side of the punch 4, and cooperates with the transmission between the upper connecting rod 21 and the lower connecting rod 20, so that the stripper plate 5 scrapes on one side of the punch 4, and the stripper plate 5 squeezes off the gasket adhered to the punch 4. At the same time, the buffer 6 buffers between the stripper plate 5 and the punch 4, thus avoiding damage to the punch 4. Finally, the gasket falls into the material receiving plate 7, which is convenient for subsequent processing and waste collection.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
