[0029] The heating component 4 is an existing mechanism and is not the object of protection in this application. Therefore, the internal structure and working principle of the heating component 4 will not be described in detail. However, it should be understood that when the heating component 4 is working, it can heat and plasticize the LED lampshade.

[0030] The cooling mechanism 3 includes a cavity 301 opened inside the lower mold body 2. An annular metal heat conductive plate 302 and a spiral tube 303 are provided inside the cavity 301. The annular metal heat conductive plate 302 is fixedly connected to the inner wall of the cavity 301. By setting the annular metal heat conductive plate 302, the efficiency of heat transfer can be accelerated, and subsequent heat exchange work is convenient.

[0031] The bottom end and top end of the spiral tube 303 are respectively connected to a liquid outlet pipe 304 and a liquid inlet pipe 306, and the outer surfaces of the liquid outlet pipe 304 and the liquid inlet pipe 306 are respectively fixedly connected to the two sides of the inner wall of the lower mold body 2, and the bottom ends of the liquid outlet pipe 304 and the liquid inlet pipe 306 successively penetrate the lower mold body 2 and the bottom plate 1 and extend to the bottom of the bottom plate 1.

[0032] By limiting the positions of the liquid outlet pipe 304 and the liquid inlet pipe 306, a certain support effect can be provided to the spiral tube 303, so that the spiral tube 303 can be stably placed inside the cavity 301 through the liquid outlet pipe 304 and the liquid inlet pipe 306 fixedly connected to the inner wall of the lower mold body 2, thereby facilitating the spiral tube 303 to perform water circulation and transportation inside the cavity 301.

[0033] An outlet pump 305 is installed inside the outlet pipe 304, and a suction pump 307 is installed at the bottom end of the inlet pipe 306.

[0036] By limiting the positions of the liquid outlet pump 305 and the liquid suction pump 307, the cooling water in the water tank 308 can be circulated and transported in sequence through the liquid inlet pipe 306, the spiral tube 303 and the liquid outlet pipe 304, which can accelerate the cooling of the LED lampshade formed inside the lower mold body 2 and save time.

[0037] A drain port 310 is installed on the bottom surface of the water tank 308 , and a valve is arranged inside the drain port 310 . Two symmetrical rectangular openings 311 are arranged on the upper surface of the water tank 308 , and evenly distributed vents 312 are arranged on the inner wall of the cavity 301 .

[0038] By setting the drain port 310, the cooling water in the water tank 308 can be easily discharged. By setting the rectangular port 311, cooling water can be easily added to the water tank 308, so that the forming mold in the lower mold body 2 can be quickly cooled. By setting the vent 312, the circulation of air inside and outside the cavity 301 can be accelerated, thereby achieving an auxiliary cooling effect.

[0039] The water tank 308 has a stirring mechanism 5 inside, which includes a servo motor 501 fixedly connected to the bottom surface of the bottom plate 1. The inner top wall of the water tank 308 is rotatably sleeved with three rotating rods 502, and the outer surface of each rotating rod 502 is fixedly connected to a stirring rod 503.

[0040] Each stirring rod 503 is located inside the water tank 308. By setting the stirring rod 503, when the rotating rod 502 rotates, the stirring rod 503 can be driven to rotate, so that the stirring rod 503 stirs the cooling water in the water tank 308, accelerates the volatilization of heat in the cooling water, and is beneficial to the reuse of the cooling water.

[0041] The top of each rotating rod 502 is fixedly connected to a sprocket 504, a chain 505 is provided above the water tank 308, the three sprockets 504 are connected by the chain 505, and the output shaft end of the servo motor 501 is fixedly connected to the top of the rear rotating rod 502 among the three rotating rods 502.

[0042] By driving the servo motor 501 to work, the rotating rod 502 fixedly connected to its output shaft end can be rotated first, and through the three sprockets 504 and a chain 505, the other two rotating rods 502 can also be rotated, so that the three rotating rods 502 can all rotate to accelerate the heat dissipation of the cooling water in the water tank 308.

[0043] The four corners of the bottom surface of the base plate 1 are fixedly connected with bottom columns 6, and the bottom surface of each bottom column 6 is fixedly connected with a mounting pad 7. By setting the bottom columns 6 and the mounting pads 7, the device can be fixed on the workbench, which facilitates and stabilizes the production of LED lampshades.

[0044] The specific implementation process of the utility model is as follows: when the LED lampshade is being molded, it can be heated by driving the heating component 4. When the molding is completed, the liquid discharge pump 305 and the liquid suction pump 307 are driven to work. When the liquid suction pump 307 is working, the cooling water in the water tank 308 can be transported to the top of the spiral tube 303 through the liquid inlet pipe 306, and then the water is discharged into the water tank 308 through the liquid outlet pipe 304 connected to the bottom end of the spiral tube 303. At this time, the operation of the liquid discharge pump 305 can accelerate the discharge of the cooling water in the liquid outlet pipe 304, so that the cooling water in the water tank 308 can be circulated and transported through the liquid inlet pipe 306, the spiral tube 303 and the liquid outlet pipe 304. At this time, the annular metal heat conduction plate 302 can accelerate the effect of heat transfer. By setting The spiral tube 303 can increase the contact area and improve the quality of heat exchange, so as to accelerate the cooling of the LED lampshade after molding in the lower mold body 2, save time and facilitate the demolding of the LED lampshade. In the above process, it is also necessary to start the servo motor 501 to accelerate the heat dissipation of the cooling water in the water tank 308. When the servo motor 501 is started, it will drive the rotating rod 502 fixedly connected to its output shaft end to rotate, and then through the three sprockets 504 and a chain 505, it will drive the other two rotating rods 502 to rotate. In this way, the simultaneous rotation of the three rotating rods 502 can make the stirring rod 503 fixedly connected to the surface thereof stir the cooling water in the water tank 308, thereby achieving the effect of accelerating the heat dissipation in the cooling water, which is conducive to the reuse of cooling water.
