Abstract:
1. A casting mold set comprising: a core that includes a casting shape forming part for forming a shape of a casting that is formed by the casting mold set and a core print that does not contribute to form the shape of the casting; a first mold that is located above the casting shape forming part of the core; and a second mold that is opposed to an upper surface of the core print of the core; wherein; in a case where the mold set is closed before molten metal is fed, a minimum clearance between the casting shape forming part and the first mold is smaller than a minimum clearance between the upper surface of the core print and the second mold that is opposed to the upper surface of the core print, so that the upper surface of the core print does not contact the second mold that is opposed to the upper surface of the core print, wherein the casting shape forming part is configured to float upward when molten metal is fed into the closed mold set so that the minimum clearance between the casting shape forming part and the first mold disappears.
