Zusammenfassung:PROBLEM TO BE SOLVED: To provide a mold structure which crushes the internal cavity of a cast to make a dense and uniform metallographic structure and attains a higher strength during high-temperature casting.SOLUTION: The mold structure used for a mold structure 2 for casting, includes an upper mold 5 and a lower mold 6 that can be close and apart to/from each other, an intermediate mold 7 that forms a cavity C between the upper and lower molds and is movable in the vertical direction therebetween so that a molten metal to be poured into the cavity may be pressurized, and a floating means (floating cylinder 3) for floating the intermediate mold relative to the lower mold.
