[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Figure 1-Figure 5 This is an embodiment of the utility model. During the production process of lampshades, since the existing lampshades are produced by injection molding, the lampshades are still in a relatively high temperature state just after being formed. If they are stacked without cooling, they are easily deformed. Therefore, the solution currently adopted is to use the above-mentioned LED lampshade cooling device to place the formed lampshades on the conveyor belt 3 and slowly convey them to achieve the cooling effect. However, this cooling method has a poor cooling effect and requires the conveyor belt 3 to run very slowly to have enough time for the lampshade to cool, which greatly affects the work efficiency. Therefore, in response to the problems generated during the cooling process of the lampshades, this embodiment specifically describes a solution, which is a cooling structure for injection molding of headlamp lampshades. The combination of the cooling bin 2 and the carrier 4 can reduce the contact area between the injection molded lampshade and the conveyor belt 3 during the movement of the injection molded lampshade on the conveyor belt 3, thereby reducing the vibration force generated during the mechanical transmission process that causes the injection molded lampshade structure to bend or deform.

[0026] A cooling structure for injection molding of a headlamp shade is specifically described, which comprises a supporting base frame 1, a water recovery tank 5 for recovering cooling water is installed in the space enclosed by the supporting base frame 1, a cooling bin 2 for cooling the shade is arranged on the supporting base frame 1, the cooling bin 2 comprises a bin body 21 and a water cooling part 22 and an air cooling part 23 installed on the top wall of the bin body 21, a conveyor belt 3 for conveying to the cooling bin 2 is arranged on the supporting base frame 1, a plurality of drain holes are opened on the conveyor belt 3, a carrier 4 for loading the injection molded shade is conveyed on the conveyor belt, the shade is first placed on the carrier 4, the carrier 4 is gradually approached to and enters the cooling bin 2 by the conveyor belt 3, in order to facilitate control The opening and closing of the water cooling part 22 and the air cooling part 23 are performed by setting an infrared sensor at the port of the warehouse body 21 and connecting it to the controller. After the infrared sensor detects the obstruction, it transmits a signal to the controller, and the controller drives the water cooling part 22 or the air cooling part 23 to open. After a preset time, the controller controls it to close. In the process of moving to the cooling warehouse 2, the heat exchange with the surrounding air reaches a certain degree of heat dissipation, and then after entering the warehouse body 21, the water cooling part 22 first acts on the lampshade. In order to reduce the impact force of water droplets on the lampshade, in this embodiment, a spray nozzle is used to connect the pipe extending from the outside to the water cooling part 22. The specific model of the spray nozzle is: SUE15B. As the conveyor belt 3 is conveyed, the lampshade will be affected by the air cooling part 23, which will enhance the evaporation rate of the water mist and increase the heat dissipation effect of the lampshade.

[0027] The carrier 4 includes a fixed carrier 41 and a movable carrier 42, wherein the fixed carrier 41 includes a base plate 44 and a receiving seat 412 mounted on the base plate 44, and a plurality of support rods 413 for supporting the injection-molded lampshade are mounted on the receiving seat 412. In the fixed carrier 41, the receiving seat 412 is in a stationary state relative to the base plate 44, that is, the base plate 44 and the receiving seat 412 are rigidly connected by bolts, and thus, the fixed carrier 41 is only applicable to production lines with certain models and matching sizes. The movable carrier 42 is applicable to production lines with inconsistent sizes of lampshades. Specifically, the movable carrier 42 includes a carrier frame 43, and a plurality of base plates 44 are mounted in the carrier frame 43. A plurality of top rods 45 for supporting the injection-molded lampshade are arranged on the base plate 44. The carrier frame 43 is U-shaped, and the base plate 44 slides in the carrier frame 43 and stops at a suitable position under manual control. The arrangement of the fixed carrier 41 and the movable carrier 42 can effectively adapt to different types of injection-molded lampshades. The base plate 44 arranged in the movable carrier 42 can be adjusted at different intervals, which can enhance the adaptability of injection-molded lampshades with different signals.

[0028] The supporting frame 43 includes a left-right symmetrical cross plate 431 and a connecting rod 432 connecting two cross bars. A movable channel 433 is provided on the cross bar. The movable channel 433 is connected to a through hole 434 that runs through the upper end of the cross bar. The left and right ends of the base plate 44 are both installed with extension plates 46 extending toward the movable channel 433. The upper end of the extension plate 46 is provided with an elastic member 47. The elastic member 47 includes a compression spring 471 installed on the extension plate 46, and a telescopic rod connected to the compression spring 471. The telescopic rod is connected to an inner plate 472 whose size is adapted to the through hole 434. A part of the structure of the inner plate 472 is protruding outside the through hole 434. The extension plate 46 is slidably arranged on the extension plate 46. In the movable channel 433, the opening height of the movable channel 433 is equal to the sum of the heights of the extension plate 46 and the elastic member 47. Therefore, when it is necessary to adjust the position of the substrate 44, first manually press down the inner plate 472 so that it is compressed to fit the extension plate 46, and then insert it into the movable channel 433 to push the substrate 44 to slide. Then, when passing through the first through hole 434, the inner plate 472 is pushed out by the compression spring 471. If this position is not suitable, the inner plate 472 is pressed back along the through hole 434, and the substrate 44 is pushed to make it continue to slide until it moves to a suitable position. After the lampshade is put on the top rod 45, it is placed on the conveyor belt 3 and enters the cooling bin 2 for cooling.

[0029] The water-cooling component 22 includes a water-cooling mounting plate 221 disposed on the top wall of the warehouse body 21, and a plurality of water outlet pipe heads 222 disposed equidistantly are disposed on the water-cooling mounting plate 221. The air-cooling component 23 includes an air-cooling mounting plate 231 installed between adjacent water-cooling mounting plates 221, and a plurality of air outlets 232 are provided on the air-cooling mounting plate 231 to discharge air into the warehouse body 21 to reduce the temperature in the warehouse body 21. The water-cooling mounting plate 221 and the air-cooling mounting plate 231 are both provided with a plurality of water outlet pipe heads 222 or air outlets 232 disposed on adjacent water-cooling mounting plates 221 or air-cooling mounting plates 231, and are staggered to increase the full-position cooling of the injection-molded lampshade.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
