Description

Technical Field

[0001] This utility model relates to the field of injection-molded lunch box processing, and in particular to a cooling device for injection-molded lunch box processing. Background Technology

[0002] Injection-molded lunch boxes are manufactured using injection molds. The fixed mold and the moving mold are quickly closed, and then the injection molding liquid for the lunch box is poured into the moving mold and the fixed mold. After the injection molding liquid inside the injection mold cools down, a complete injection-molded lunch box is formed.

[0003] The prior art patent application with publication number CN221834910U proposes to improve the cooling efficiency of injection-molded lunch boxes by installing a blower mechanism and a moving mechanism, and combining air cooling with coolant. At the same time, by adjusting the position of the moving seat, the surface area for air cooling is increased, thereby improving the processing speed of injection-molded lunch boxes.

[0004] The fixed mold body has a first cooling tank inside, and the moving mold body has a second cooling tank inside. The first and second cooling tanks are designed with a wave shape. When the fixed mold body and the moving mold body are closed, the first and second cooling tanks will be connected. After the coolant enters the first cooling tank, it will be discharged from the second cooling tank. The wave shape design can increase the contact area between the coolant and the inner wall of the first and second cooling tanks, thereby improving the cooling efficiency.

[0005] However, in order to facilitate rapid cooling of the molded lunch boxes during the current injection molding process, coolant is added and a fan is installed on the outside of the device for rapid cooling. However, when the fan is installed on the outside of the device for cooling, it can only cool the outside of the device, but cannot use the airflow generated by the fan to cool the lunch box inside the device.

[0006] Therefore, it is necessary to provide a cooling device for injection-molded lunch boxes to solve the above-mentioned technical problems. Utility Model Content
