[0032] Among them, a handle 29 is fixedly connected to the outer end surface of the push plate 3, which is convenient for pulling the push plate 3. The card slot 9 is a triangular slot, and the card block 8 is a triangular block, which is convenient for moving the push plate 3 and can control the number of sliding plates 10 that are raised according to the required die hole size. There are multiple sliding plates 10, and an inclined surface is provided on the sliding plate 10. The inside of the push plate 3 is an inclined surface.

[0034] A specific application of this embodiment is:

[0035] When the size of the mold hole needs to be changed, the handle 29 is grasped and the push plate 3 is pushed inward. The push plate 3 is moved by the roller 5 below. When the front end inclined surface of the push plate 3 contacts the inclined surface of the sliding plate 10, the sliding plate 10 will slide up due to the oblique force. When the sliding plate 10 rises to the top, the first limit block 30 will be stuck by the first limit groove 31, so that it cannot continue to rise. At this time, the upper end surface of the annular mold 11 is horizontal with the upper end surface of the lower mold box 1. When the push plate 3 is pushed to the top, the roller 5 will be stuck by the slide groove 4 and cannot continue to move. During the pushing process, each time a sliding plate 10 is pushed up, a corresponding block 8 will be stuck in the slot 9. When the sliding plate 10 rises, it will stand on the push plate 3, so that it can be placed stably. At the same time, because the sliding plate 10 gives the push plate 3 a vertical force, it will not cause the push plate 3 to move, and the block 8 will limit the movement of the push plate 3. Then, the punching size is changed, and the punch ring 18 outside the punch 16 is rotated by the rotating rod 36, and the fixed block 35 is moved from above the transposition groove 34 to below the transposition groove 34. At this time, the lower end surface of the punch ring 18 is horizontal with the lower end surface of the punch 16, so as to achieve the purpose of adjusting the size of the punch 16.

[0036] When in use, the motor 26 is started, and the output shaft of the motor 26 drives the reciprocating mechanism 27 to move, and the reciprocating mechanism 27 drives the piston 28 to move. The hydraulic press 24 is used to pump oil through the oil pipe 25 into the piston groove. The piston rod 19 is moved by oil pressure to cause the upper mold box 15 to slide up and down to perform the punching operation. When the punching is completed, the waste will fall on the upper end surface of the support rod 22. The handle 29 is grasped to pull out the push plate 3. At this time, the sliding plate 10 drives the annular mold 11 to descend, and the waste will be in the discharge trough 12. Then, the pull rod 32 is grasped and the discharge plate 13 is used to push the waste out of the discharge trough 12 to achieve the purpose of cleaning the waste.
