Gravity casting generally refers to a process in which molten metal is poured into a mold under the action of gravity and formed. Cast parts typically have surface temperatures as high as 400 degrees celsius and require rapid cooling to about 80 degrees celsius followed by rapid removal from the cooling water. In this process, the cooling speed affects the uniformity of cooling, and thus the quality of the part. Especially for composite materials, cooling has a large influence on the cohesion of the material.

Wherein, the height of the cooling water level is realized by manually controlling the water inlet and outlet valves, and the requirement on the operation proficiency of an operator is too high. The part is easily overcooled due to the slow draining speed, so that the binding force of the material can not meet the functional requirement, and the metallographic structure of the composite material can not meet the standard and is discarded.

If high-pressure water supply is adopted instead to accelerate the water inlet speed, the pressure-resistant requirements on the water source flow and the pipeline are correspondingly improved, so the economic efficiency is poor, and the method is not suitable for small-batch production.

Therefore, there is a need to provide a new rapid cooling device to solve the above problems.
