The fixing mechanism includes a fixing block fixed to the front of the lower mold, side rods fixedly installed on both sides of the fixing block, sleeve plates movably installed on the outside of the two side rods, connecting plates fixedly installed on the side of the two sleeve plates that are far apart from each other, and movable rods fixedly installed on the side of the two connecting plates that are close to each other.
[0004] In the above solution, although the two sleeves can be brought closer together through the cooperation between the rotating disk and the screw, as well as the screw sleeve and the rotating rod, and the plastic parts in the lower mold can be clamped through the cooperation between the movable rod, the lower mold, and the clamping plate, thus facilitating the fixation of the plastic parts, the punching mechanism in this solution can only punch holes in plastic parts with fixed shapes in the lower mold, and the angle of the punching mechanism cannot be adjusted, making it impossible to process plastic parts with bevels or other shapes. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] Please combine Figures 1-5This embodiment of a punching device for processing plastic parts includes a worktable 1. First fixing blocks 2 are fixedly connected to the top of the worktable 1 near its vertically parallel sides. A first rotating shaft 3 is rotatably connected to the inner side of one of the first fixing blocks 2. A first track 4 is fixedly connected to the outer side of a pair of first fixing blocks 2. Second fixing blocks 5 are fixedly connected to the top of the worktable 1 near its horizontally parallel sides. A second rotating shaft 6 is rotatably connected to the inner side of one of the second fixing blocks 5. A second track 7 is fixedly connected to the outer side of a pair of second fixing blocks 5. A base 8 is mounted at the top of the first track 4 and the second track 7. An electric push rod 9 is fixedly connected to the bottom of the base 8. A punching mechanism 10 is fixedly connected to the bottom of the electric push rod 9. A first servo motor coaxial with the first rotating shaft 3 is fixedly connected to the outer side of one of the first fixing blocks 2. The machine 11 has a second servo motor 12 coaxial with the second rotating shaft 6 fixed to the outer side of one of the second fixed blocks 5. The first servo motor 11 fixed to the outer side of one of the first fixed blocks 2 drives the first rotating shafts 3 rotatably connected to the inner side of the first fixed blocks 2 to rotate, so that the first track 4 fixed to the outer side of the pair of first rotating shafts 3 in an arc shape can rotate back and forth, so that the punching mechanism 10 at the bottom of the base 8 can punch holes in the plastic parts on the worktable 1 at different vertical and horizontal angles. The second servo motor 12 fixed to the outer side of one of the second fixed blocks 5 drives the second track 7 fixed to the outer side of the pair of second rotating shafts 6 in an arc shape to rotate left and right, so that the punching mechanism 10 at the bottom of the base 8 can punch holes in the plastic parts on the worktable 1 at different horizontal angles.
[0028] Combination Figure 1 , Figure 2 and Figure 4 The top of the workbench 1 is fixed with multiple fixed plates 13 arranged in a circular array. Telescopic columns are fixed to the inner side of the fixed plates 13, and contact plates 14 are fixed to the ends of the telescopic columns. The telescopic columns are divided into a first telescopic column 15 and a second telescopic column 16. One end of the first telescopic column 15 is fixed to the fixed plate 13, and a return spring 17 is fixed to the bottom inner end of the first telescopic column 15. The other end of the return spring 17 is fixed to the second telescopic column 16, and the second telescopic column 16 slides inside the first telescopic column 15. Multiple telescopic columns are arranged at the top of the workbench 1. A fixed plate 13 arranged in a circular array has a telescopic column fixedly connected to its inner side, and multiple contact plates 14 fixedly connected to the ends of the telescopic columns to abut against the plastic parts, thereby achieving the limitation and fixation of the plastic parts. Since the telescopic columns are divided into a first telescopic column 15 and a second telescopic column 16, and a return spring 17 is installed inside the first telescopic column 15, the second telescopic column 16 is slidably connected to the first telescopic column 15, so that the contact plates 14 fixed to the ends of the second telescopic column 16 can limit and fix plastic parts of different sizes.
[0029] Combination Figure 5The workbench 1 has a through hole 18 in the middle. The bottom of the workbench 1 is located directly below the through hole 18 and is equipped with a collection box 19 for collecting punching debris. The bottom of the collection box 19 is equipped with a roller 20 and a handle 21 is fixed to the outside of the collection box 19. Multiple through holes 18 are arranged linearly in the middle of the workbench 1, so that the debris generated by the plastic parts when subjected to the punching mechanism 10 falls into the collection box 19 at the bottom of the workbench 1 for collection.
[0030] The implementation principle of a punching device for processing plastic parts in this application embodiment is as follows:
[0031] Before punching, the first servo motor 11 is turned on to drive the first rotating shaft 3 connected to the inner side of the first fixed block 2 to rotate clockwise by 45 degrees, and the second servo motor 12 drives the second rotating shaft 6 connected to the inner side of the second fixed block 5 to rotate counterclockwise by 45 degrees, so that the base 8 is located above the upper left corner of the workbench 1, ensuring space for the plastic parts to be placed.
[0032] At this point, the plastic part is placed from top to bottom, so that the four contact plates 14 follow the size of the plastic part and move adaptively toward the fixed plate 13. At the same time, the second telescopic column 16 fixed to the inner side of the contact plate 14 will slide inside the first telescopic column 15 and compress the return spring 17 fixed to the bottom of the first telescopic column 15 toward the fixed plate 13 until the contact plate 14 is completely attached to the surface of the plastic part.
[0033] Then, based on the position of the plastic part to be punched, the first servo motor 11 fixed to the outside of one of the first fixed blocks 2 is adaptively activated to drive the first rotating shaft 3 rotatably connected to the inside of the pair of first fixed blocks 2 to rotate, so that the first track 4 fixed to the outside of the pair of first rotating shafts 3 in an arc shape can rotate back and forth, so that the punching mechanism 10 at the bottom of the base 8 can punch the plastic part on the worktable 1 at different vertical and horizontal angles; the second servo motor 12 fixed to the outside of one of the second fixed blocks 5 drives the second track 7 fixed to the outside of the pair of second rotating shafts 6 in an arc shape to rotate left and right, so that the punching mechanism 10 at the bottom of the base 8 can punch the plastic part on the worktable 1 at different horizontal angles;
[0034] If punching is performed on the inclined surface of a plastic part, the angles of rotation of the first servo motor 11 and the second servo motor 12 are adjusted according to the position of the inclined surface to adjust the distance the base 8 moves in the vertical direction of the first track 4 and the horizontal direction of the second track 7, so that the punching mechanism 10 is parallel to the inclined surface. Then, the electric push rod 9 fixed to the bottom of the base 8 is activated to drive the punching mechanism 10 closer to the inclined surface and perform punching.
[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
