Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy casting, in particular to a combined aluminum alloy casting mold. Background Art

[0002] The products produced by aluminum alloy smelting are mostly sold in the form of aluminum alloy ingots. Aluminum alloy ingots are cast into finished products of different sizes according to customer requirements. Existing aluminum alloy molds are mostly formed in one piece during manufacturing, and the shape is fixed after the mold manufacturing is completed. This results in that during the casting process of aluminum alloy ingots, molds of the same specification can only cast alloy ingots of the same specification. If the casting specifications need to be changed, new molds can only be manufactured, resulting in the inability to use the old molds, causing great waste; and after the aluminum alloy is cooled, the aluminum alloy ingots are not easy to demold due to the different expansion coefficients with the mold material. It is necessary to pre-apply a demolding agent or knock to assist in removing the aluminum alloy ingot. After long-term use, graphite molds are easily broken or cracked, resulting in scrapping, which increases production costs. Utility Model Content
