2. A cooling body is installed on the outer side of the molding groove of the utility model. After the electric heater is subjected to high-temperature treatment and molding, the water inlet pipe in the cooling body is used to quickly inject cold water. At this time, the cold water is stored in the cooling water tank, and the cooling water tank Installed on the outside of the forming press tank, so that the model formed in the forming press tank can be cooled quickly. The diameter of the inlet pipe is smaller than the diameter of the outlet pipe, so that there is always cold water in the cooling water tank, and there will be no heat exchange due to heat exchange. The cooling effect and speed of the cooling body caused by insufficient cold water supply.
