A method for heat treating a mold cast product by releasing the product from a mold and hardening the product. Since the mold release is performed when a surface layer of the product held in contact with the mold has a hardening allowing temperature and after it becomes a shell-shaped solidified layer, the product immediately after release from the mold has a heat suitable for hardening. Using this heat, the product is thereafter hardened by means of a cooling agent. As a result, a heating process required for hardening can be omitted, thereby achieving energy conservation.

Method for heat treating mold cast product

A mold casting process comprises, after pouring of a molten metal into a mold, rapidly cooling that surface layer of a cast product which is in contact with a mold, and releasing the resulting product from the mold when the surface layer thereof has been converted into a shell-like solidified layer. Such process is used for casting a mechanical part blank and apparatus for carrying out the process is provided.
