Abstract
A pair of mold bases are provided, each of which possesses a nest-mold insert hole which is open in one direction perpendicular to the mold-closing direction and capable of receiving a plurality of nest molds. The plurality of nest molds, with contacting wall faces between adjacent members, are inserted into the insert hole of each mold base from the open side of the insert hole. In order that the nest molds will not slip in the mold-closing direction, a wall-face engagement is applied between the nest molds and the inner wall of the insert hole and between the nest molds themselves. Mutually corresponding nest molds on both the mold bases, except substitute nest molds, form the cavity for molded products. The nest molds put in the insert hole are fixed by being pushed by a fixing device from the open side of the insert hole.
