[0027] Through the above technical solution, by setting the clamping mechanism 9, by pulling the pull rod 91 to drive the insertion rod 92 to retract into the inside of the placement plate 3, the lower mold 4 can be removed from the placement plate 3, thereby realizing the function of replacing the lower mold 4.

[0028] Specifically, a pressure plate 10 is provided below the fixed plate 7, and both sides above the pressure plate 10 are fixedly connected to one end of the sliding guide rod 6. A through groove 11 is provided on the pressure plate 10, and the through groove 11 is provided directly below the punching rod 8. Two pressure plate springs 12 are provided between the pressure plate 10 and the fixed plate 7, and the two pressure plate springs 12 are both sleeved on the sliding guide rod 6, and both ends of the pressure plate spring 12 are in conflict with the fixed plate 7 and the pressure plate 10.

[0029] Through the above technical solution, by setting the pressure plate 10 and the pressure plate spring 12, the hydraulic cylinder 5 is started to push the fixed plate 7 to move. Under the action of the pressure plate spring 12, the pressure plate 10 and the fixed plate 7 can be pushed down at the same time, and the pressure plate 10 can be made to contact the paper first to fix it in position, which can prevent the position of the paper from being shifted during punching.

[0030] Specifically, a mold spring 15 is provided in the inner wall of the placement plate 3, one end of the mold spring 15 is fixedly connected to the inner wall of the placement plate 3, and the other end of the mold spring 15 is fixedly connected to the second top plate 16, the upper part of the second top plate 16 is in conflict with the lower part of the lower mold 4, and there are four mold springs 15 and four second top plates 16 distributed at the four lower corners of the lower mold 4.

[0031] Through the above technical solution, by setting the mold spring 15 and the second top plate 16, the second top plate 16 can push the lower mold 4 to pop out from the placement plate 3 through the force of the mold spring 15 itself, so that the lower mold 4 can be replaced, and it is convenient for the staff to replace the lower mold 4, which increases the convenience of the staff in replacing the lower mold 4.

[0032] Specifically, a collection drawer 17 is provided inside the base 1, and the punching hole 14 on the lower mold 4 is connected with the interior of the collection drawer 17 through the placement plate 3 and the base 1. One side of the collection drawer 17 passes through the inner wall of the base 1 and is slidably connected thereto, and a handle 18 is fixedly connected to one side of the collection drawer 17.

[0033] Through the above technical solution, by setting up the collection drawer 17 and the handle 18, the punched debris can be collected, and the collection drawer 17 can be pulled out from the inside of the base 1 by pulling the handle 18, so that the debris inside the collection drawer 17 can be easily dumped uniformly, and by setting the collection drawer 17 inside the base 1, the normal use and operation of the staff will not be affected when the staff uses the device.

[0034] Specifically, the other end of the insertion rod 92 is configured as an inclined surface with a certain angle, and the insertion rod 92 is disposed in a square body.

[0035] Through the above technical solution, the other end of the insertion rod 92 is set to an inclined surface with a certain angle. When installing the lower mold 4, the lower mold 4 is pressed with a slight force, and the guiding effect of the inclined surface will overcome the force of the insertion rod spring 94, so that the insertion rod 92 is retracted to the inside of the placement plate 3. At the same time, when the position of the lower mold 4 is pressed to a certain position, the force of the insertion rod spring 94 will push the first top plate 93 to make the pull rod 91 drive the insertion rod 92 to be inserted into the interior of the lower mold 4. By setting the insertion rod 92 in a square body, the inclined surface of the insertion rod 92 can always face upward, preventing the insertion rod 92 from rotating inside the placement plate 3, which makes it inconvenient to install the lower mold 4.

[0036] Specifically, the pressing plate 10 is lower than the punching end of the punching rod 8 in a natural state, and the punching end of the punching rod 8 is located inside the through slot 11 on the pressing plate 10 in a natural state.

[0037] Through the above technical scheme, by the position of the pressing plate 10 being lower than the punching end of the punching rod 8 in a natural state, the pressing plate 10 can first contact the paper to fix the paper in position, and by the punching end of the punching rod 8 being located inside the through groove 11 on the pressing plate 10 in a natural state, the punching rod 8 can be shielded on all sides, and foreign objects can be prevented from colliding with the punching rod 8 and causing it to deform, thereby playing a certain protective role.

[0038] Working principle: When in use, firstly, the punching size and shape of the paper is made according to the factory requirements, the lower mold 4 and the punching rod 8 are selected, and the punching rod 8 is replaced. By pulling the pull rod 91, the insertion rod 92 is retracted to the inside of the placement plate 3, and the mold spring 15 can be used to make the second top plate 16 push the lower mold 4 to pop out from the placement plate 3, so as to remove the old lower mold 4 from the placement plate 3, and then align the new lower mold 4 with the slot on the placement plate 3, and then install the lower mold 4 on the placement plate 3 by applying a slight force, so as to replace the new lower mold 4, and then place the paper on the placement plate 3 On the top, the hydraulic cylinder 5 is started to push the fixed plate 7 to drive the punching rod 8 to be pressed down, and the fixed plate 7 will push the pressure plate spring 12. Under the action of the pressure plate spring 12, the pressure plate 10 and the fixed plate 7 are pushed down at the same time, and the pressure plate 10 can be made to contact the paper first to fix it in position, which can prevent the position of the paper from being shifted during punching. When the punching rod 8 completes the upward movement of the paper, the hydraulic cylinder 5 will drive the fixed plate 7 to drive the punching rod 8 to move up. At the same time, the fixed plate 7 will conflict with the fixed block 13 when moving up, so that the fixed plate 7 drives the sliding guide rod 6 to move up, thereby moving the pressure plate 10 up.

[0039] 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.
