How to cool the mold in the production of aluminum alloy gravity casting machine?

Every time a product is produced, it will wait for the temperature of the gravity casting mold to cool to a certain temperature before casting. Do you know what method is usually used to cool the mold in the production of gravity casting machine? Come and have a look with Kuntai Casting Machine.　　 Because the natural cooling method takes too long, which will reduce the production efficiency, the forced cooling method is usually used to cool the gravity casting mold. There are three cooling methods, namely air cooling, indirect water cooling and direct water cooling. Air cooling is to use air blowing to cool, strengthen convection to achieve the effect of heat dissipation. The advantage of this method is that the structure is simple and easy to manufacture, but the effect is not good enough.　　Indirect water cooling refers to placing a water jacket on the back or part of the mold for cooling. The disadvantage of this method is that some castings cannot be produced with intense cooling, otherwise it is easy to increase casting defects. Direct water cooling is to directly pass water into the water jacket for cooling. The disadvantage of this method is that it is expensive and only suitable for mass production.
