[0006] Furthermore, a guide member and an elastic member are provided between the upper clamping plate and the pressing plate, and the guide member and the elastic member ensure that the pressing plate can first press the plate to be processed before punching, and facilitate the removal of the processed plate after punching.

[0007] Furthermore, at each punching station, the number of the punching needles is three, including a No. 1 punching needle located in the middle position and a No. 2 punching needle located inside and outside the No. 1 punching needle.

[0008] Furthermore, at each punching station, the number of the slider is one, and the lower surface of the slider is processed with a No. 1 bevel groove and a No. 2 bevel groove, the direction of the No. 1 bevel groove is opposite to the No. 2 bevel groove, the position of the No. 1 bevel groove corresponds to the No. 1 punch needle, and the position of the No. 2 bevel groove corresponds to the No. 2 punch needle.

[0009] Furthermore, the driving assembly includes a plurality of air cylinders and oil cylinders as driving sources, and a slider sliding plate arranged inside and outside as a transmission member. The air cylinder and the oil cylinder are both fixed on the upper mold base and drive the slider sliding plate to move laterally. The slider sliding plate is fixedly connected to the slider to drive the slider to move synchronously laterally.
