The bottom ends of the inner cavities of the multiple punch holes 41 are fixedly connected with springs 43, and the top ends of the multiple springs 43 are fixedly connected with multiple top pillars 44 respectively; both sides of the base 1 are fixedly connected with connecting plates 5, and the opposite ends of the two connecting plates 5 are rotatably connected with connecting shafts 51, and the two connecting shafts 51 are fixedly connected to the lower mold 4. A pushing mechanism is installed on one side of the bottom of the lower mold 4, and the pushing mechanism includes a notch 53 opened on the base 1 and a notch 53 opened on the bottom of the lower mold 4. The slide groove 56 is provided with a push rod motor 54 in the notch 53, and a slider 57 is slidably connected in the slide groove 56. A pin seat 55 is installed on the slider 57. The pin seat 55 is rotatably connected to the driving end of the push rod motor 54 through a pin shaft. The air conditioner cover is clamped on the surface of the lower mold 4 through the right-angle baffle 42, which is not only convenient for personnel to take the air conditioner cover after punching, but also can limit the air conditioner cover to avoid displacement during punching and affect the quality of punching. In addition, during punching, the punch head 32 will squeeze the top column 44 to press the spring 43. Compression, when the stamping is completed, the elastic force of the spring 43 pushes the push column 44 to push the stamped debris out of the stamping hole 41, and then starts the push rod motor 54, cooperates with the slider 57 to slide in the slide groove 56, the pin seat 55 is rotatably connected to the driving end of the push rod motor 54 and one side of the lower mold 4 is rotatably connected to the connecting plate 5 through the connecting shaft 51, so that the lower mold 4 can be rotated and tilted with the connecting shaft 51 as a circle, so that the debris generated by the stamping on the surface of the lower mold 4 can be automatically cleaned, thereby avoiding the problem that the debris is inconvenient for personnel to clean.
