PROBLEM TO BE SOLVED: To provide a structure of a mold for casting a plurality of long casts and a manufacturing method for the same capable of improving productivity while preventing occurrence of variation in quality.SOLUTION: A structure of a mold for casting long casts comprises a plurality of molds 11 provided with vertical runners 15 in mating surfaces 13 of a pair of vertically positioned split dies 12 are integrated with the split dies 12 arranged back-to-back to position respective mating surfaces 13 in parallel. Horizontal runners 19 communicating lower parts of both vertical runners of a plurality of molds 11 with each other are formed. A sprue cap 18 is provided at the top edge of one of vertical runners 15 in the plurality of molds 11. The lower a position in each of the vertical runners 15 in the plurality of molds 11 is, the smaller a passage cross sectional area is.SELECTED DRAWING: Figure 2 |
