る。EXAMPLES Examples of the present invention will be described below with reference to FIGS. The mold 1 comprises a mold body 2 and a unit mold 3. The mold body 2 is composed of a casting mold 4 and an upper mold 5 made of a sand layer 5a held in the casting mold 4 and a lower mold 7 made of a casting mold 6 and a sand layer 7a held in the casting mold 6. ing. In the sand layer 5a of the upper die 5, there is a sprue 8 vertically penetrating and a horizontal runner 11 connected to a lower end portion 9 of the sprue 8 and drilled along a lower surface 10 of the upper die 5. The sand layer 7a of the lower mold 7 is formed with fitting holes 12 for the runners 11
The unit mold part 3 is fitted in the fitting hole 12. The unit mold part 3 is composed of mold pieces 13, 14 and 15 made of green sand with adjacent side surfaces adhered, and communicates with the vertical product cavity 16 and the upper part of the product cavity 16 and also with the runner 11. The feeder unit 17 is provided.

きる。According to the present invention, a plurality of unit mold parts having product cavities are molded in advance, and the unit mold parts are arranged in the mold body, so that the dimensional accuracy of the product cavities can be easily increased. In particular, when one product cavity is formed in one unit mold part, the dimensional accuracy of the product cavity can be increased more easily, casting with high dimensional accuracy can be easily cast, and the product yield of the casting can be increased. Improve,
Production cost is reduced. In addition, since the mold body is formed of a pair of half molds, the sprue and runner are formed in one half mold, and the unit mold part is arranged in the other half mold. The deformation of the unit mold portion that occurs during the die matching can be reduced, and a casting with high dimensional accuracy can be cast more easily.
