Casting method of aluminum alloy precise casting plate for tool molds and tools

The invention relates to nonferrous metal casting, and in particular relates to a casting method of an aluminum alloy precise casting plate for tool molds and tools. According to the casting method, due to optimization design of components of a special aluminum alloy, and improvement of a smelting process and a casting process, the aluminum alloy precise casting plate for tool molds and tools can be manufactured. The casting method is simple, and the aluminum alloy precise casting plate is fine and uniform in tissue, very low in internal stress, and high in later machining size precision. The properties such as strength, electric conductivity, oxidation, welding, polishing and machining of the aluminum alloy precise casting plate are remarkably improved, and the requirements of the industrial manufacturing field of tool molds and tools are met.
