The end is fixedly connected to the threaded rod 9 to drive the threaded rod 9, so that the limiting block 16 can move left and right to facilitate the confirmation of the punching position. The upper part of the fixed seat 5 is fixedly connected to the sliding rod 8, and the lower part of the fixed seat 5 is threadedly connected to the threaded rod 9. The middle part of the threaded rod 9 is threadedly connected to the limiting block 16. An infrared emitter 10 is fixedly connected to one side of the limiting block 16. The infrared emitter 10 will emit visible infrared rays and guide them to the top of the mold, so that the punching position can be predicted in advance. The lower part of the limiting block 16 is fixedly connected to the second telescopic rod 21, which moves back and forth between the limiting block 16 and the second motor 11. The extension end of the second telescopic rod 21 is fixedly connected to the second motor 11. The lower part of the second motor 11 is fixedly connected to the punching head 12. The second motor 11 drives the punching head 12 to complete the punching task at the position where the mold needs to be punched.

[0024] Racks 7 are fixedly connected to both the left and right sides of the worktable 2. Sliders 29 are fixedly connected to both the lower sides of the worktable 2. The slides 29 are slidably connected to the slide grooves 28 to control the back-and-forth movement of the worktable 2 on the base frame 1. Gears 23 are rotatably connected to the middle of both upper sides of the base frame 1. Knobs 22 are fixedly connected above the gears 23 and control the gears 23. Limiting plates 20 are fixedly connected below the gears 23. Pin holes 27 are opened on both sides of the base frame 1 near the gears 23. Fixing pins 24 pass through the pin holes 27 and the limiting plates 20 to fix the rotation position of the gears 23. The gears 23 mesh with the racks 7 to complete the back-and-forth movement of the worktable 2 on the base frame 1. The workbench 2 is movable, and several power fixing blocks 15 are fixedly connected to the four corner edges to fix the position of the first telescopic rod 14 and provide power to the first telescopic rod 14. The middle of the workbench 2 is provided with a first drop hole 17 to prevent the generated waste from being left outside and to smoothly enter the waste collection area for convenient subsequent processing and recycling. The first telescopic rod 14 is fixedly connected to the side of the power fixing block 15 near the first drop hole 17. The extension end of the first telescopic rod 14 is fixedly connected with a right angle gripper 13. The right angle gripper 13 mainly fixes the mold on the workbench 2 to facilitate subsequent punching requirements. There are four power fixing blocks 15 and four first telescopic rods 14. The middle of the slide bar 8 is slidably connected to the limit block 16.

[0025] Working principle: Before starting work, place the mold on the worktable 2 above the base frame 1. Use the right-angle gripper 13 to fix the mold on the worktable 2. Then, turn on the infrared emitter 10 to determine the drilling direction. Then, use the knobs 22 on the gears 23 on both sides above the base frame 1 to control the rotation of the gears 23. A slider 29 is fixedly connected to the bottom of the worktable 2, and there are sliding grooves 28 on both sides above the base frame 1. The slider 29 is slidably connected to the sliding grooves 28, so that the gears 23 can adjust the forward and backward movement of the worktable 2. The limiting plate 20 below gear 23 will also rotate accordingly. After confirming the coordinates of the punching hole required by the mold, the worktable is limited by the fixing pin 24 passing through the pin hole 27 and the limiting plate 20. Then, the threaded rod 9 is driven by the first motor 6 on one side of the fixed bracket 4 to move between the limiting block 16 and the fixed seat 5, so that the limiting block 16 moves left and right on the slide rod 8, which drives the second telescopic rod 21, the second motor 11 and the punching head 12 to move left and right, thereby confirming the coordinates of the punching hole. When working, the worktable... The operator only needs to place the mold in the center of the workbench 2. Then, the power fixing blocks 15 at the four corners of the workbench 2 will drive the first telescopic rod 14 to drive the right-angle grippers 13 on both sides to control the mold. After that, the second telescopic rod 21 extends to drive the second motor 11. The second motor 11 starts to drive the punching head 12 until the punching head 12 completes punching the mold. After punching is completed, the second telescopic rod 21 will retract to drive the second motor 11. The generated waste will fall into the waste bin 19 through the first drop hole 17 and the second drop hole 25. Since the second drop hole 25 is larger than the first drop hole 17, even when the workbench 2 moves back and forth, the waste can still fall completely into the waste bin 19 through the first drop hole 17 and the second drop hole 25. Then, the operator can take out the mold for replacement. After long-term operation, the operator can take out the waste bin 19 in the concave baffle 26 above the support frame 3 through the handle 18, recycle the waste in it, and put it back into the concave baffle 26.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
