Description

Technical Field

The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding and processing fields such as complex-shaped products. The injection mold refers to the mold used in injection molding. It generally has two upper molds and lower molds that can be docked with each other. After the upper and lower molds are docked, the shaping liquid is injected from the pouring port, and the injection molded product can be obtained after it is cooled and demolded. During the injection molding process, the lunch box injection mold generally needs to be cooled and cooled to improve the molding efficiency. The existing cooling and cooling generally uses a coolant to perform cooling on the lunch box injection mold, and the cooling pipe extends to the inside of the lunch box injection mold to achieve heat dissipation of the mold. However, the surface and internal temperatures of the lunch box injection mold are uneven, which will cause uneven molding of thin lunch boxes. At the same time, the cooling time of the lunch box injection mold is long, which affects the next processing of the lunch box injection mold and the use effect is not good. Therefore, in order to avoid the shortcomings of the prior art, it is necessary to improve the prior art. Utility Model Content
