Description

Technical Field

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

[0002] With the development of technology, aluminum alloy die-castings are widely used in various fields. In the production process of aluminum alloy die-castings, continuous production is often carried out. Usually, after smelting aluminum alloy solution, it is poured into a die-casting machine, and then continuous die-casting is carried out to continuously produce aluminum alloy die-castings to achieve batch production. In the aluminum alloy die-casting production line, it is often necessary to cool the aluminum alloy die-castings to make them fixed and formed.

[0003] Existing aluminum alloy die-castings are often placed on a conveyor belt during cooling, and then the air-cooling machine is started. When one side is cooled, it is necessary to manually flip the aluminum alloy die-casting to cool the other side. Although this method is simple, it takes too much time and is time-consuming and laborious. Moreover, in very few cases, the aluminum alloy die-castings are not cooled in time, which will cause cracks and affect their performance. At the same time, it will also affect the production efficiency of aluminum alloy die-castings. For this reason, we have proposed an air-cooling device for aluminum alloy die-castings.
