[0024] Working principle: When working, first place the piece to be punched inside the punching groove 2, then start the hydraulic rod 4, push the pressure plate 5 downward, the pressure plate 5 drives the punching knife 6 downward to punch the piece to be punched inside the punching groove 2, and then the hydraulic rod 4 drives the punching knife 6 to move up and reset, and at the same time start the motor 10, drive the driving gear 11 to rotate, the driving gear 11 drives the transmission gear 12 to rotate, the transmission gear 12 drives the transmission rod 13 to rotate, the transmission rod 13 drives the sector gear 14 to rotate, the sector gear 14 rotates in the first half of the circle, the sector gear 14 drives the transmission rack 15 to move upward, the transmission rack 15 drives the movable rod 16 to move upward, the movable rod 16 drives the positioning sleeve 22 to slide upward on the outside of the positioning slide rod 23, the positioning sleeve 22 drives the positioning slider 24 in the positioning slide groove The internal sliding of 25 can ensure that the movable rod 16 achieves better stability when moving. At the same time, the movable rod 16 moves upward to stretch the tension spring 20, causing the tension spring 20 to undergo elastic deformation. At the same time, the movable rod 16 pushes the movable plate 18 to move upward, and the movable plate 18 pushes the punching piece out of the punching groove 2. When the sector gear 14 rotates the second half of a circle, the sector gear 14 is disengaged from the transmission rack 15, causing the movable rod 16 to lose its driving force. Under the dual action of the rebound force of the tension spring 20 and gravity, the movable rod 16 moves downward and resets, and the movable plate 18 also moves downward and resets to the inner bottom end of the punching groove 2. In this way, the punching device for mold product processing can be used to eject the punching piece inside the punching groove after punching, thereby improving work efficiency and achieving better practicality.
