Abstract

The invention discloses a direct casting technology for a pure aluminum metal mold. The technology comprises steps as follows: molten aluminum is prepared, a mold is prepared, preheated, mounted, cast, cooled and opened, and a cast is cleaned. Compared with a sand casting technology and a metal mold casting technology, the direct casting technology has the advantages that the material loss caused by secondary smelting is reduced, the production efficiency of castings is increased by 5-10 times, and meanwhile, the quality of casting products is further improved.
