To provide a frame body for tire mold casting in which the uneven distribution of temperature upon pouring is suppressed, thus, while preventing the generation of the leakage of molten metal, capable of producing a casting of high quality free from casting blow holes and having high dimensional accuracy.

The frame body for tire mold casting has an almost cylindrical shape, arranged around a mold for a tire mold and used for the casting of a tire mold. The outer circumference thereof is provided with a plurality of, suitably, three sprues 4A to 4C at equal intervals. In this invention, it is possible that only one sprue among the plurality of spruess is used as a sprue for molten metal pouring, and, the remaining sprues are used as dummy sprues.
