Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy die casting technology, and in particular to a uniform cooling device for aluminum alloy die casting. Background Technology

[0002] Aluminum alloy die castings are aluminum alloy parts produced through a die casting process, widely used in the automotive, electronics, electrical, aerospace, and machinery industries. Die casting is a manufacturing process in which molten metal is injected under high pressure into a precision mold and cooled to form the final shape. It is suitable for mass production of precision metal parts. During the processing of aluminum alloy die castings, the workpiece needs to be cooled and shaped.

[0003] Traditional cooling devices for aluminum alloy die castings typically employ either air cooling or water cooling alone. However, air cooling alone has low efficiency, while water cooling can cause thermal stress when the cooling water is sprayed onto the aluminum alloy die casting, which can easily lead to cracking of the workpiece and affect product quality.

[0004] Therefore, a uniform cooling device for aluminum alloy die castings is proposed. Utility Model Content
