PROBLEM TO BE SOLVED: To provide a mold device for molding resin, enabling a resin pattern for highly reliable casting of a pipe body having a long length in the de-molding direction with a complicated shape to be manufactured at a time, hardly causing the occurrence of joint marks on a cast product.SOLUTION: A mold device 11 for molding a resin pattern 101 for casting of a pipe body includes: a pair of female molds 12 and 13 opposed to each other with a mold opening/closing operation in Z axis direction; a male mold A1 (A) which is fitted to a fixed shaft 14 and extends in Y axis direction so as to be disposed between the pair of female molds 12 and 13; a male mold B1 (B) which is fitted to a first slide mechanism 15 sliding in Y axis direction between the pair of female molds 12 and 13, with the outer diameter of the split molds narrowly operated by a rack and pinion mechanism 16, and a male mold C which is fitted to a second slide mechanism 17 sliding in X axis direction at a height position between the male mold A and the male mold B. |
