PURPOSE: A mold for casting a metallic mold, main parts of which are formed of heterogeneous cast materials, is provided to reduce the collision and mixing between heterogeneous molten metals to ensure the strength of the main parts. CONSTITUTION: The mold(51) for casting a metallic mold formed of composite cast materials comprises a central cavity(53), a first molten metal inlet(57) disposed at one side of the mold and extended to the bottom of the cavity, and a second molten metal inlet(59) extended to the middle of the cavity. In the mold, the second molten metal inlet(59) comprises: a vertical injection part(61) for guiding the molten metal downwardly; and an inclined injection part(63) integrally formed with the vertical injection part(61) for injecting the molten metal supplied from the vertical injection part into the cavity with a certain upward slope in the vertical upward direction.
