[0034] With reference to Figure 3The cooling assembly includes a cooling box 7 installed on the bottom wall of the lower mold 1, which serves as the core storage component of the cooling assembly and is used to store the cooling medium. A water pump 8 is installed at the front of the cooling box 7, with its input end inside the cooling box 7 and its output end provided with a cooling pipe 9. The water pump 8 plays a key role in driving the circulation of the cooling medium. Its input end extracts the cooling medium from the cooling box 7, which is then delivered to the cooling pipe 9 through the output end. Through the continuous operation of the water pump 8, the cooling medium can be continuously circulated in the cooling system, so that heat can be transferred from the knife mold and the material to the cooling medium in time and carried away, thereby achieving effective cooling effect and maintaining the normal working temperature of the knife mold. The cooling pipe 9 is arranged around the mold groove 5, forming a low-temperature area around the mold groove 5 and directly cooling the cutting area. The end of the cooling pipe 9 away from the water pump 8 is provided with a first return pipe 11, and the end of the first return pipe 11 away from the cooling pipe 9 is arranged inside the cooling box 7. The first return pipe 11 returns the cooling medium that has absorbed heat through the cooling pipe 9 to the cooling box 7, forming a complete cooling medium circulation loop. The outer wall of the first return pipe 11 is provided with a switching assembly, which switches the return path of the cooling medium according to the temperature condition of the cooling system.

[0035] Referring to Figure 4 The switching assembly includes a housing 15 installed on the outer wall of the first return pipe 11, which serves as the protective shell and mounting base of the switching assembly, providing a stable installation environment for the thermostat 16, connecting rod 17, piston 18 and other components inside, and also plays a role in isolating external interference. The thermostat 16 is installed inside the housing 15 and is the core temperature sensing component of the switching assembly, which can monitor the temperature of the cooling medium in real time. The output end of the thermostat 16 is fixedly connected with the connecting rod 17, which is used to slide and drive the piston 18 to slide. The connecting rod 17 is fixedly connected with the piston 18 on the side away from the thermostat 16. The piston 18 changes the return path of the cooling liquid by sliding. The outer wall of the connecting rod 17 is sleeved with a first spring 19, which provides a certain elastic resistance and reset force for the movement of the piston 18, making the movement of the piston 18 more stable and controllable. The outer wall of the housing 15 is provided with a second return pipe 13, which provides another return channel for the cooling medium when switching the cooling path.

[0036] Referring to Figure 6The jacking assembly comprises a plurality of jacking rods 20 which are slidingly connected inside the lower die 1 and can move up and down in the vertical direction. After cutting is completed, the jacking rods 20 are jacked up by the driving assembly to push out the cut material in the die groove 5. The outer wall of the jacking rod 20 is fixedly connected with a blocking block 22, the top of the blocking block 22 is fixedly connected with a second spring 23, and the combination of the blocking block 22 and the second spring 23 provides buffering and limiting functions for the movement of the jacking rod 20.

[0037] With reference to Figure 6 The driving assembly comprises a push rod 24 which is slidingly connected to the inner wall of the lower die 1 and serves as a power transmission component of the driving assembly. The outer wall of the push rod 24 is fixedly connected with a limiting block 25 which is used to limit the push rod 24. The side of the limiting block 25 close to the jacking rod 20 is fixedly connected with a third spring 26 which plays an auxiliary role to make the push rod 24 return to the initial position stably.

[0038] With reference to Figure 1 and Figure 2 The top of the upper die 3 is fixedly connected with a connecting block 4 which serves as a connecting interface for the upper die 3 to connect with external driving equipment. The bottom of the lower die 1 is fixedly connected with a mounting plate 10, and the bottom of the mounting plate 10 is installed with a heat evenly plate 12. The outer wall of the first return pipe 11 is arranged inside the heat evenly plate 12, and the heat evenly plate 12 plays a role of evenly dissipating heat. Since the heat carried by the cooling medium in the first return pipe 11 will be distributed unevenly during the return process, the heat evenly plate 12 can further evenly distribute the heat to improve the heat dissipation efficiency.

[0039] With reference to Figure 3 The bottom of the lower die 1 is installed with a heat dissipation fin 14, and the outer wall of the second return pipe 13 is arranged inside the heat dissipation fin 14. The heat dissipation fin 14 can increase the contact area between the bottom of the lower die 1 and the air to improve the heat dissipation effect.

The end of the second return pipe 13 away from the shell 15 is arranged inside the cooling tank 7 to ensure that the cooling liquid can flow into the cooling tank 7 after being cooled.

[0040] With reference to Figure 4The outer wall of the piston 18 is slidingly connected inside the shell 15, and the sliding connection of the piston 18 inside the shell 15 ensures the linearity and stability of the movement of the piston 18, so that the piston 18 can accurately control the switching of the flow direction of the cooling medium under the joint action of the thermostat 16 and the first spring 19, one end of the first spring 19 is fixedly connected to the outer wall of the thermostat 16, the other end of the first spring 19 is fixedly connected to one side of the piston 18 close to the thermostat 16, and the first spring 19 is connected between the thermostat 16 and the piston 18, when the thermostat 16 moves due to temperature change, the first spring 19 can play a buffering and auxiliary adjusting role, so that the movement of the piston 18 is more stable, and sudden movement of the thermostat 16 is avoided, so that the piston 18 moves too fast or unstable, thereby improving the reliability and control accuracy of the switching assembly.

[0041] Referring to Figure 6 The top rod 20 is fixedly connected with a top plate 21 at the top, the top plate 21 increases the contact area of the top rod 20 with the cutting material, so that the top rod 20 can more uniformly apply force when ejecting the material, reducing the risk of damage to the material due to excessive local stress, and the bottom wall of the top rod 20 and the end of the push rod 24 away from the limiting block 25 are both inclined, when the push rod 24 moves under the action of external power, the inclined end surface interacts with the inclined bottom wall of the top rod 20, converting the horizontal pushing force into the upward lifting force of the top rod 20, this inclined matching structure is simple and has high transmission efficiency, which can ensure that the lifting assembly works stably and reliably under the action of the driving assembly, and realizes smooth ejection of the material.

[0042] Working principle: when the laser cutter is needed, the connecting block 4 is installed on the punch machine, and the water pump 8 at the bottom of the lower die 1 is started, then the punch machine is started to drive the upper die 3 to slide, further driving the module 6 to slide, and the article is punched, in the punching process, the cooling liquid in the cooling tank 7 is flowed around the mold groove 5 under the action of the cooling pipe 9, thereby cooling the mold groove 5, the flowed cooling liquid is cooled again by the first return pipe 11 and the thermostat 16, and then returns to the inside of the cooling tank 7, when the temperature of the cooling liquid is too high, the paraffin in the thermostat 16 is melted, thereby pushing the connecting rod 17 and the piston 18 to slide, and the first return pipe 11 is blocked, so that the cooling liquid is cooled by the second return pipe 13 and the heat dissipation fin 14, and flows into the cooling tank 7, when the punching is completed, the two push rods 24 are pressed to slide the push rod 24 to eject the top rod 20, thereby driving the top plate 21 to be ejected, facilitating the taking of the punched article.

[0043] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
