Specifically, a punching groove 21 corresponding to the punch 11 is arranged on the lower mold 2, and the punch 11 punches the main board by cooperating with the punching groove 21 during the downward movement of the punch 11. A clearance hole 121 corresponding to the punch 11 is arranged on the pressing plate 12, and the punch 11 can pass through the clearance hole 121 downward; specifically, the two ends of the elastic member 123 are fixedly connected to the top of the pressing plate 12 and the bottom of the lower mold 2, respectively, and when the elastic member 123 is in a normal state, the height of the bottom of the pressing plate 12 is lower than the height of the bottom of the punch 11.

When the upper die 1 moves downward to drive the punch 11 to punch the mainboard, the pressure plate 12 first contacts the mainboard, and then the upper die 1 continues to move, so that the elastic member 123 is compressed. Under the elastic force of the elastic member 123, the non-punching positions on the mainboard are pressed against the die, and then the punch 11 contacts the mainboard again to punch. Under the action of the pressure plate 12, the mainboard is not easily pulled and deformed under the impact of the punch 11.

Specifically, a row of multiple holes is opened on the main board, and multiple punches 11 are also set at the bottom of the upper mold 1. The multiple punches 11 correspond one by one to the multiple holes that need to be punched on the main board. The lower mold 2 is provided with multiple grooves 21 corresponding to the multiple punches 11, and the pressure plate 12 is provided with multiple clearance holes 121 corresponding to the multiple punches 11.

Specifically, two guide rods 122 are provided, and the two guide rods 122 are respectively arranged at positions close to the two ends of the pressure plate 12 ; the elastic member 123 is configured as a spring, and an elastic member 123 is respectively sleeved outside the two guide rods 122 .

Specifically, the present embodiment also includes a support plate 3 arranged on one side of the die, a feed box 4 arranged on the support plate 3, a collection box 7 arranged on the side of the die away from the support plate 3, and a push plate 5 for pushing the main board for loading and unloading; the push plate 5 is used to push the main board in the feed box 4 onto the die and to push the main board that has been punched on the die into the collection box 7.

Specifically, there is a gap between the bottom of the feed box 4 and the support plate 3, and the distance between the bottom of the feed box 4 and the top of the support plate 3 is equal to the thickness of the main board. The main board in the feed box 4 is arranged horizontally; the two ends of the bottom of the feed box 4 are provided with pads 41 fixedly connected to the support plate 3. The two ends of the main board in the feed box 4 are aligned with the two ends of the main board when it is processed on the die.

Since the distance between the feed box 4 and the support plate 3 is equal to the thickness of the main board, the main board at the bottom of the feed box 4 will fall to the top of the support plate 3, and then the push plate 5 will push the main board falling on the support plate 3 from the side of the feed box 4 away from the die to the top of the die, and then wait for the main board to be punched. After the punching is completed, the push plate 5 continues to move and pushes the main board to move into the collection box 7, and then the push plate 5 moves in the direction away from the collection box 7 until the push plate 5 moves to the side of the feed box 4 away from the die.

Specifically, two push plates 5 are provided, and the two push plates 5 are symmetrically arranged at the middle position of the length direction of the main board. The length direction of the two push plates 5 is horizontal and perpendicular to the length direction of the main board.

Specifically, the present embodiment further includes a positioning assembly, which includes a side positioning plate 22, an end positioning plate 23 and a lifting frame 24; specifically, the side positioning plate 22 is arranged at a position of the die near the collection box 7, and two end positioning plates 23 are provided and are arranged at positions near both ends of the die, and after the main board moves onto the die, the two ends are respectively fitted with the two end positioning plates 23, and the side away from the collection box 7 is fitted with the side positioning plate 22. The side positioning plates 22, the end positioning plates 23 and the push plate 5 are used to achieve positioning of the pressure plate 12.

Specifically, in order to prevent the side positioning plates 22 and the end positioning plates 23 from obstructing the sliding of the main board into the collection box 7, the side positioning plates 22 and the end positioning plates 23 are arranged to be able to slide up and down on the die, so that the top height of the side positioning plates 22 and the end positioning plates 23 can slide to a height lower than the top height of the die.

Specifically, the lifting frame 24 is arranged below the die, and the bottoms of the side positioning plates 22 and the end positioning plates 23 are fixedly connected to the top of the lifting frame 24. The side positioning plates 22 and the end positioning plates 23 are driven to move up and down by the up and down movement of the lifting frame 24. Specifically, a cylinder is fixedly connected to the bottom of the die, and the piston rod of the cylinder is fixedly connected to the lifting frame 24 to drive the lifting frame 24 to move up and down.
