Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy casting production, in particular to a heating device for a metal mold of an aluminum alloy casting. Background Technique

[0002] In the prior art, when producing aluminum alloy castings, a pouring mold is required.

[0003] However, the molds used in the prior art do not have a heating structure. Therefore, during pouring, the casting material enters the interior of the mold through the nozzle and flows. Since the temperature difference between the interior of the mold and the temperature of the casting material is relatively large, the cooling speed of the material is relatively fast, thereby reducing the fluidity of the material inside the mold, resulting in incomplete filling parts on the casting, and it is easy to have flow marks on the surface of the product, reducing the quality of the product.

[0004] Therefore, we propose a heating device for a metal mold of an aluminum alloy casting. Content of the Utility Model
