Description

Technical Field

[0002] A mold is a tool used to manufacture parts or products. Its design and manufacture directly affect the quality and shape of the output parts. In the mold manufacturing process, demoulding performance is crucial. Factors such as demoulding angle, surface finish, and material hardness need to be considered. In the mold demoulding process, the characteristics of the material used for the part will also affect the difficulty of demoulding. Different types of materials, such as plastics, metals, etc., may require different methods and processes for demoulding. In the process of mold demoulding, cooling is a crucial link. Effective cooling can help the material in the mold solidify quickly, reduce adhesion and deformation, and thus facilitate smooth demoulding.

[0003] In the existing mold demolding process, multiple steps are usually required to perform cooling and demolding. First, the mold is opened by a mold opening device, then a cooling device is used to reduce the temperature of the mold and the workpiece, and finally the demolding device is used to perform the demolding operation. This multi-step artificial cooling and demolding method not only increases the workload of the staff, but also greatly reduces the work efficiency of mold demolding. For this reason, we propose a cooling device for mold demolding. Utility Model Content
