[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Reference Figure 1-Figure 3The utility model provides an embodiment: a punching machine that is easy to replace molds, including a punching machine body 1 and a guide plate 3, the guide plate 3 is located on the outside of the punching machine body 1, and a placement table 4 is fixedly connected to the side of the guide plate 3 away from the punching machine body 1, and a mold block 2 is slidably connected to the middle of the punching machine body 1, and a through groove 7 is opened in the middle of the mold block 2, and the guide plate 3 contacts the surface of the mold block 2.

[0042] When in use, the material is transported from the placement table 4 to the punching machine body 1, and at the same time, under the action of the guide plate 3, it is aligned with the notch of the mold block 2 and passes through the through slot 7, so as to be shaped and cut.

[0043] Reference Figure 2 and Figure 3 Two movable plates 11 are slidably connected inside the punching machine body 1, and a top block 10 is slidably connected to the middle of the punching machine body 1. The top block 10 is located between the two movable plates 11. One end of the movable plate 11 away from the top block 10 passes through the punching machine body 1 and is slidably connected to the middle of the mold block 2. Grooves 13 are provided on both sides of the mold block 2. One end of the two movable plates 11 away from the top block 10 is slidably connected to the middle of the two grooves 13 respectively. A push rod 6 is fixedly connected to the outside of the top block 10. The other end of the push rod 6 passes through the punching machine body 1 and is fixedly connected to the pressing block 5.

[0044] When in use, the pressing block 5 is pressed, and the push rod 6 is pushed by the pressing block 5. The push rod 6 pushes the top block 10 to slide inside the punching machine body 1, so that the two movable plates 11 in contact with the top block 10 are squeezed and slide to both sides, and the two corner positions are pulled out from the middle of the mold block 2. After the movable plate 11 is pulled out, the mold block 2 loses its limit, so that it can be quickly taken out and disassembled, and the operation is convenient to improve the disassembly efficiency.

[0045] Reference Figure 2 and Figure 3 An elastic component is installed inside the punching machine body 1, and the elastic component includes multiple round rods 8. The multiple round rods 8 are fixedly connected inside the punching machine body 1, and the outer sides of the multiple round rods 8 are sleeved with compression springs 9. Two movable plates 11 are slidably connected to the outer periphery of the multiple round rods 8 respectively.

[0046] During use, when installing the mold block 2, press the pressing block 5 so that the movable plate 11 is squeezed and pushed by the top block 10. When the movable plate 11 slides, it will slide on the outer periphery of the round rod 8 under the limitation of the round rod 8, thereby squeezing the compression spring 9 on the outer periphery of the round rod 8, insert part of the mold block 2 into the middle of the punching machine body 1, and release the pressing block 5. The compression spring 9 loses pressure and pushes the movable plate 11 to contact the mold block 2, and slowly pushes the mold block 2, so that the groove 13 on the outer periphery of the mold block 2 can be aligned with the corner of the movable plate 11, so that the corner of the movable plate 11 can be inserted into the groove 13, and the mold block 2 is fixed, thereby improving the installation efficiency and stability of the mold block 2.

[0047] Reference Figure 4 and Figure 5 A guide assembly is installed on the outer side of the punching machine body 1, and the guide assembly includes a collecting bucket 14, which is fixedly connected to the outer side of the punching machine body 1, a drainage groove 19 is opened in the middle of the punching machine body 1, and the drainage groove 19 is located above the collecting box 15, and the middle part of the punching machine body 1 is slidably connected with the collecting box 15, and a stopper 17 is rotatably connected to the outer side of the punching machine body 1, and the stopper 17 contacts with the collecting box 15, and a limiting block 18 is fixedly connected to the outer side of the collecting box 15, and a limiting groove 12 is opened in the middle of the punching machine body 1, and the limiting block 18 is slidably connected to the middle of the limiting groove 12, and a pull rod 16 is fixedly connected to the outer side of the collecting box 15.

[0048] During use, after the material passes through the through groove 7 and is shaped and cut, waste residue will fall. Since the collecting bucket 14 is located below the outlet of the through groove 7, the waste residue generated during cutting can fall into the collecting bucket 14 and enter the drainage groove 19 under the guidance of the bevel of the collecting bucket 14. It falls into the collecting box 15 through the drainage groove 19 and is collected, so as to facilitate the collection and cleaning of the waste residue and prevent the waste residue from being scattered on the ground due to shaking of the external collecting barrel. At the same time, under the action of the stopper 17, the stability of the collecting box 15 in the punching machine body 1 is improved. After the rotating stopper 17 no longer contacts the collecting box 15, the pull rod 16 can be pulled to pull out the collecting box 15, so as to facilitate the cleaning of the waste residue in the collecting box 15.

[0049] Working principle: Press the pressing block 5 to push the push rod 6, so that the push rod 6 pushes the movable plate 11 to slide out from the middle of the mold block 2, so that the mold block 2 can be quickly taken out, improving the efficiency of disassembly and replacement of the mold block 2. At the same time, the movable plate 11 will squeeze the compression spring 9 when moving. After releasing the pressing block 5, the compression spring 9 will push the movable plate 11, so that the mold block 2 can be quickly fixed in the middle of the punching machine body 1, improving the installation efficiency;

[0050] After the material is shaped and cut by the through groove 7, the waste residue will enter the drainage groove 19 through the collecting bucket 14 and fall into the collecting box 15 through the drainage groove 19, so as to facilitate the collection and cleaning of the waste residue, thereby improving the stability of the waste residue collection and preventing the external collection device from shaking and causing the waste residue to fall to the ground.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
