[0002] With the continuous development of social economy and the continuous improvement of people's consumption level, some restaurants and milk tea shops have gradually developed their business. When operating restaurants and milk tea shops, they often need a large number of disposable plastic cups for customers to use or for filling milk tea. When producing such convenient disposable plastic cups, the use of thermoforming molds is one of the main production methods. After thermoforming, the product needs to be demoulded. At this time, the cup liner needs to be cooled to enable the product to be demoulded quickly.

[0003] For example, the Chinese utility model application number "202320978881.9" discloses a plastic cup processing thermoforming device, which mainly has a cooling unit on the upper mold. After the product is formed, a driving mechanism is provided to drive the cooling unit to move to the formed product for cooling. This operation is complicated and inefficient. There are also conventional cooling methods, such as cooling with water on the outside of the punch, and the punch is close to the cup liner. In this way, the heat exchange efficiency is also low, and it is difficult to cool quickly. Utility Model Content
