The outside of the first gear 212 is meshed with a second gear 214, and the second gear 214 is rotatably connected to the front of the mounting plate 211. The outside of the wheel 214 is meshed with a second tooth plate 215, and the second tooth plate 215 is slidably connected to the inside of the collection box 1. The right side of the second tooth plate 215 is fixedly connected to a slider 216, and the slider 216 is slidably connected to the inside of the collection box 1. The bottom of the slider 216 is fixedly connected to a push plate 217, and the push plate 217 is slidably connected to the inside of the collection box 1. The upper mold 37 descends and drives the first tooth plate 213, which can make the push plate 217 move synchronously, and the waste generated by stamping can be pushed out by the push plate 217. The collection box 1 is at the corresponding position between the second tooth plate 215 and the slider 216. A slide groove is provided at the position, and the second tooth plate 215 and the slider 216 slide inside the slide groove, and the slide groove limits and guides the slider 216 to make the push plate 217 move smoothly to prevent the push plate 217 from getting stuck when moving. The suction component 22 includes a support frame 221, and the support frame 221 is fixedly connected to the left side of the collection box 1. The interior of the support frame 221 is fixedly connected to an air pump 222, and an air suction port 223 is fixedly connected between the air pump 222 and the collection box 1. The interior of the air suction port 223 is fixedly connected to a protective plate 224, and the air inside the collection box 1 is extracted through the air suction port 223. The air in the collecting box 1 is sucked by the air pump 222, thereby generating suction. A ventilation groove is provided inside the push plate 217, and the collecting box 1 is provided with a through hole at the corresponding position of the lower mold 5. The through hole between the lower mold 5 and the collecting box 1 facilitates the waste to fall into the collecting box 1, thereby facilitating discharge of the waste.

[0028] In this embodiment, the stamping mechanism 3 includes a limiting cylinder 31, which is fixedly connected to the top of the collection box 1. The interior of the limiting cylinder 31 is slidably connected to a slide rod 32, a spring 33 is fixedly connected between the slide rod 32 and the limiting cylinder 31, and a pad 34 is fixedly connected to the outside of the slide rod 32. The top of the collection box 1 is fixedly connected to a limiting rod 35, the interior of the collection box 1 is fixedly connected to a hydraulic rod 36, the top of the hydraulic rod 36 is fixedly connected to an upper mold 37, and the upper mold 37 is slidably connected to the limiting rod 35. Externally, a pin 38 is fixedly connected to the bottom of the upper mold 37, and the upper mold 37 is driven down by the hydraulic rod 36, so that the pin 38 cooperates with the lower mold 5 to complete the stamping of the workpiece, and the impact of the upper mold 37 is slowed down by the pad 34. There are two limit cylinders 31, and the positions of the two limit cylinders 31 and the upper mold 37 are symmetrical. The first tooth plate 213 is fixedly connected to the left side of the upper mold 37, and the upper mold 37 is evenly buffered by the two pads 34, so that the force is more evenly distributed, thereby preventing the upper mold 37 from being unevenly stressed.

[0029] During actual operation, when this device is used, the hydraulic rod 36 drives the upper mold 37 to descend, and the upper mold 37 slides on the outside of the limit rod 35. The upper mold 37 drives the ejector pin 38. The upper mold 37 descends and first contacts the pad 34. The pad 34 drives the slide bar 32. The slide bar 32 compresses the spring 33, thereby buffering the upper mold 37. The limit cylinder 31 is used to limit the slide bar 32. The ejector pin 38 cooperates with the lower mold 5 to stamp the workpiece. When the upper mold 37 descends, it drives the first tooth plate 213. The first tooth plate 213 drives the first gear 212. The first gear 212 drives the second gear 214. The second gear 214 drives the second tooth plate 215. The second tooth plate 215 drives the slider 216. The slider 216 drives the ejector pin 38. When the plate 217 slides to the left and the upper mold 37 punches the workpiece, the push plate 217 is at the leftmost side of the collection box 1. The first gear 212 and the second gear 214 are different in size, so the rotation of the first gear 212 will accelerate the second gear 214. When the push plate 217 is on the left, the air pump 222 is started, and the air pump 222 extracts the air inside the collection box 1 through the air intake 223 and discharges it. The protective plate 224 is used to prevent impurities from entering the air pump 222. The air inside the collection box 1 is extracted, and suction will be generated through the lower mold 5 and the through groove of the collection box 1 to suck the waste into the inside of the collection box 1. Then, when the upper mold 37 is reset, the push plate 217 moves to the right, pushing the waste to open the flip door 4, thereby discharging the waste.
