[0032] Specifically, the punch blade 10 can be driven by the air cylinder 4 to move downward to punch the clamped mold, and the movable block 20 outside the rotating lead screw 19 can be driven to move left and right inside the fixed frame 18, and the punch blade 10 at the bottom of the movable block 20 can move with it, so that the mold can be punched at different positions according to the actual needs of the user, thereby meeting various mold processing needs. However, the punch blade 10 is prone to excessive wear and damage after long-term use. At this time, the movable rod 12 is rotated, the gear 13 is rotated, the rack 16 engaged with the gear 13 is moved rightward in the T-shaped slot 14 until the limiting block 17 is separated from the limiting slot 9. In this process, the limiting of the limiting rod 8 is released, and the limiting rod 8 can be removed from the hole 7. It is simple to disassemble and replace the punch blade 10.

[0033] Referring to Figure 1 and Figure 2 , the clamping mechanism 2 includes a micro motor 201, a transmission belt 204, and a connecting rod 210. The micro motor 201 is fixedly connected to the inner bottom left end of the hollow base 1. A rotating rod 202 is rotatably connected to the inner bottom right end of the hollow base 1. The rotating rod 202 and the output end of the micro motor 201 are both fixedly connected with a belt pulley 203. The two belt pulleys 203 are drivingly connected by the transmission belt 204. The output end of the micro motor 201 and the top end of the rotating rod 202 are both fixedly connected with a disc 205. The top side of the disc 205 is fixedly connected with a fixed rod 206. The top end of the fixed rod 206 is rotatably connected with a first rotating shaft 207. The hollow base 1 is provided with U-shaped plates 208 on both sides. One end of the U-shaped plate 208 penetrates through the hollow base 1 and is rotatably connected with a second rotating shaft 209. The two second rotating shafts 209 are connected with the corresponding first rotating shafts 207 through the connecting rods 210. The adjacent sides of the two U-shaped plates 208 are both provided with T-shaped clamping plates 211.

[0034] Specifically, the output end of the micro motor 201 can be driven to rotate, and the belt pulley 203 outside the output end can also start to rotate. The belt pulley 203 outside the rotating rod 202 is connected with the belt pulley 203 through the transmission belt 204, so that the transmission belt 204 can transmit energy to the belt pulley 203 outside the rotating rod 202 to make the rotating rod 202 start to rotate. At this time, the rotating rod 202 and the disc 205 at the top end of the output end of the micro motor 201 start to rotate simultaneously, and the first rotating shaft 207 also starts to rotate. The second rotating shaft 209 is connected with the first rotating shaft 207 through the connecting rod 210, so the second rotating shaft 209 also starts to rotate. The rotating force is transmitted to the second rotating shaft 209 through the connecting rod 210, causing the second rotating shaft 209 to start to rotate. At this time, the U-shaped plates 208 on both sides move to the middle until the T-shaped clamping plates 211 contact the left and right sides of the mold. This contact can limit and fix the mold to prevent the mold from shifting during processing, thereby improving the processing quality of the mold.

[0035] With reference to Figure 1 And Figure 2 , the clamping mechanism 2 further comprises two bolts 212, the two bolts 212 are respectively screwed on the top of the corresponding T-shaped clamping plate 211, and the bottom ends of the two bolts 212 are sequentially penetrated through the corresponding T-shaped clamping plate 211 and the U-shaped plate 208;

[0036] Specifically, by loosening the bolts 212, the limiting and fixing of the T-shaped clamping plate 211 can be released, and at this time different shapes of clamping plates can be replaced according to the user's needs.

[0037] With reference to Figure 1 , the top right front end of the hollow base 1 is fixedly connected with a controller 21, the controller 21 is electrically connected with the micro motor 201 and the air cylinder 4 respectively, and the outer side of the controller 21 is provided with a protective cover 22, one end of the protective cover 22 is rotatably connected with the top of the hollow base 1;

[0038] Specifically, the working of the micro motor 201 and the air cylinder 4 can be controlled by the controller 21, and the protective cover 22 can protect the controller 21 from being damaged by external factors.

[0039] With reference to Figure 1 And Figure 2 , the clamping mechanism 2 further comprises two rubber pads 213, the two rubber pads 213 are respectively fixedly connected on one side of the corresponding T-shaped clamping plate 211, and the size of the two rubber pads 213 is matched with the size of one side of the corresponding T-shaped clamping plate 211;

[0040] Specifically, the friction between the T-shaped clamping plate 211 and the mold to be processed can be further increased by the rubber pad 213, so that the mold to be processed can be placed more stably.

[0041] Working principle: when using the device, first place the mold to be processed on the hollow base 1, then limit and clamp it by the clamping mechanism 2, then drive the punch blade 10 to move downward by the air cylinder 4 to perform punching work on the clamped mold, and the movement of the movable block 20 on the outer side of the lead screw 19 will drive the punch blade 10 to move left and right, so that the mold can be punched at different positions according to the user's needs. When the punch blade 10 is damaged after a long time of use and needs to be disassembled and replaced, at this time the gear 13 can be driven to rotate by rotating the movable rod 12, and the rack 16 engaged with the gear 13 will move rightwards in the T-shaped groove 14 until the limiting block 17 is disengaged from the limiting groove 9, at this time the limiting and fixing of the limiting rod 8 can be released, then the limiting rod 8 is taken out from the hole 7, and the excessively worn or damaged punch blade 10 can be disassembled and replaced, which is relatively simple.

[0042] And before the mold is processed, first the mold is placed in the hollow base 1 top middle position, then through the micro motor 201 can drive its output end rotation, at this time its output end outside the pulley 203 will follow the rotation, the rotating rod 202 outside the pulley 203 through the transmission belt 204 will also follow the rotation and can drive the rotating rod 202 rotation, at this time the rotating rod 202 and micro motor 201 output end top disc 205 will rotate simultaneously, the first rotating shaft 207 will also follow the rotation, the second rotating shaft 209 through the connecting rod 210 will also follow the rotation and can drive both sides of the U-shaped plate 208 to move to the middle until the T-shaped clamp plate 211 and the mold left and right side contact, can be limited to the mold fixed, the mold is not easy to produce deviation when processing, so as to ensure the processing quality of the mold, the model of micro motor 201 is RS260, the model of cylinder 4 is SC type.

[0043] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for the person skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
