A locking protrusion 10 for cooperating with the locking groove 9 is provided on the side of the movable slide bar 8 away from the second spring 11. The locking protrusion 10 is locked with the locking groove 9 through the cooperation of the locking protrusion 10 and the locking groove 9, thereby realizing the locking of the annular slide column 4, so that the annular slide column 4 can be kept in a fixed position when the second circular punch 19 punches the rubber sheet. A bevel groove 14 is provided on the top of the movable slide bar 8, and a connecting groove 21 is symmetrically provided on the top wall of the through slide groove 6. An inclined surface pushing block 13 is slidably connected in the connecting groove 21. A movable block 5 is fixedly provided on the top of the inclined surface pushing block 13, and a third spring 12 is press-fittedly connected between the bottom of the movable block 5 and the top of the circular boss 3.

[0015] Advantageously or exemplarily, a first circular punch 20 is provided at the bottom of the punching mechanism 18, a second circular punch 19 is provided at the bottom of the first circular punch 20, and the diameter of the second circular punch 19 is smaller than the diameter of the first circular punch 20, thereby punching out the inner diameter and outer diameter of the sealing ring.

[0016] Beneficially or exemplarily, a guide slide rod 7 is slidably connected inside the movable block 5, the bottom of the guide slide rod 7 is fixedly connected to the top end surface of the circular boss 3, and a limiting slide head (not shown) is fixed on the top of the guide slide rod 7 to prevent the movable block 5 from moving upward beyond the travel.

[0017] Advantageously or exemplarily, a rubber sheet (not shown) to be processed is placed on the top of the lower mold body 1, thereby achieving rapid punching processing.

[0018] Advantageously or exemplarily, the lower mold body 1, the annular slide column 4 and the movable block 5 are all made of alloy material.

[0019] The utility model is used when: in the initial state, the annular slide column 4 is subjected to the top pressure of the first spring 16, so that the annular convex edge 17 is abutted against the top wall of the annular groove 15, and the top end surface of the annular slide column 4 is in the same horizontal plane with the top end surface of the lower mold body 1. At this time, the locking groove 9 and the through slide groove 6 are in corresponding relative positions, and the movable block 5 is subjected to the top pressure of the third spring 12, so that the top end surface of the movable block 5 and the top end surface of the lower mold body 1 are in the same horizontal plane. At this time, the movable block 5 drives the inclined surface pushing block 13 away from the connecting groove 21. At the same time, the movable slide bar 8 is subjected to the top pressure of the second spring 11, so that the movable slide bar 8 drives the locking protrusion 10 to cooperate and connect with the locking groove 9.

[0020] First, place the rubber sheet on the top of the lower mold body 1, and control the punching mechanism 18 to move downward until the second circular punch 19 at the bottom of the punching mechanism 18 abuts against the rubber sheet, and continue to control the punching mechanism 18 to move downward. Due to the locking of the locking protrusion 10 and the locking groove 9, at this time, the second circular punch 19 punches and cuts the rubber sheet, thereby completing the inner diameter processing of the sealing ring, and continue to control the punching mechanism 18 to move downward. At this time, the second circular punch 19 moves downward to drive the movable block 5 to overcome the top pressure of the third spring 12 and move downward. At this time, the movable block 5 drives the inclined surface push block 13 to pass through the connecting groove 21 and extend into the oblique groove 14, and then The inclined surface on the inclined surface pushing block 13 is abutted against the inclined surface in the oblique groove 14, so that the inclined surface pushing block 13 overcomes the movable slide bar 8 to drive the locking protrusion 10 away from the locking groove 9. At this time, the annular slide column 4 overcomes the top pressure of the first spring 16 and moves downward, and the first circular punch 20 punches the rubber sheet again, thereby realizing the outer diameter processing of the sealing ring; after the punching is completed, the elastic force of the first spring 16, the second spring 11 and the third spring 12 restores the movable block 5, the movable slide bar 8 and the annular slide column 4 to their initial state, and at the same time, the movable block 5 pushes the punched waste sheet out of the lower mold body 1, thereby facilitating and quickly removing the punched finished product and excess waste.

[0021] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
