[0001] The utility model relates to the technical field of casting cooling devices, in particular to an air cooling mechanism for aluminum alloy die castings. Background Art

[0002] Aluminum alloy die castings refer to aluminum or aluminum alloy equipment and devices obtained through casting. Generally, molten aluminum or aluminum alloy heated to a liquid state is poured into a cavity through a sand mold or a metal mold. Many aluminum parts or aluminum alloy parts with various shapes and sizes are usually called aluminum alloy die castings. For existing aluminum alloy die castings, during the production process, the aluminum alloy die castings on the conveyor belt are mostly placed on the conveyor belt for natural cooling. However, for the aluminum alloy die castings placed on the conveyor belt, the bottom in contact with the conveying surface of the conveyor belt has slow heat dissipation due to contact with the conveyor belt, and the heat dissipation and cooling efficiency of the upper part of the die casting itself are different.
