[0002] With the development of the automobile industry, the design and manufacturing requirements of license plate lights, as one of the important safety devices of vehicles, are becoming increasingly higher. License plate lights not only need to have good lighting effects, but also need to meet certain aesthetic and durability requirements.

[0003] The mold of the prior art is not convenient for quickly demoulding the molded part after the injection molding is completed, which reduces the practicality of the entire mold. In addition, the upper mold and the lower mold in the mold are mostly manually operated when closing or separating the mold, which is not convenient enough.

[0004] A lamp shell mold wrapped with memory material and easy to demold with announcement number CN218966048U includes a lower mold body, the outer surface of the lower mold body is sleeved with a memory material plate, a mold cavity is opened in the middle of the top of the lower mold body, both ends of the lower mold body are fixedly connected with connecting rods, the tops of the two connecting rods on one side are jointly fixedly connected with a guide device, the guide device and the two slide rails are jointly slidably connected with an upper mold body, and the top of the upper mold body is fixedly connected with an injection tube. After the injection molding of the utility model is completed, the injection molded parts are easy to demold quickly, which improves the practicality of the entire mold, and under the action of the guide device, the upper mold body can be more convenient to close or separate with the lower mold body, and manual operation is no longer required.

[0027] Working principle:

[0028] First, the mold upper shell 2 and the mold lower shell 3 are preliminarily positioned through the first mounting blocks 6 and the second mounting blocks 9 on both sides, and then the mold upper shell 2, the mold lower shell 3 and the mold body 1 are tightly fixed together using the fixing screws 7 through the first fixing holes 10, the second fixing holes 14 and the third fixing holes 18, and the sealing strip 11 ensures the sealing between the mold upper shell 2 and the mold lower shell 3;

[0029] Secondly, the molten plastic is injected into the mold through the injection port 15 inside the connecting block 5, and the pressing module 13 applies pressure below the upper shell 2 of the mold to ensure that the plastic is evenly distributed in the mold groove 12 to form the required license plate lamp housing shape. During the injection molding process, the exhaust hole 4 at the connection between the upper shell 2 of the mold and the lower shell 3 of the mold helps to exhaust the gas in the mold, prevent the generation of bubbles, and ensure the quality of the injection molded parts;

[0030] Then, after the plastic injection is completed, the coolant is injected into the mold through the coolant injection port 8 at the front of the mold body 1, and the coolant is evenly distributed in the lower shell cooling groove 16, so that the injection molded part is quickly and evenly cooled. After the cooling is completed, the used coolant is discharged through the coolant discharge port 17 at the rear of the mold body 1;

[0031] Finally, after cooling is completed, the mold upper shell 2 and the mold lower shell 3 are separated by removing the fixing screws 7, and the molded license plate lamp housing is taken out, which effectively shortens the cooling time of the injection molded part, improves production efficiency, and ensures the quality of the injection molded part. The mold is easy to assemble and disassemble, which improves work efficiency and operational flexibility.
