Abstract

PURPOSE:To enable quick and accurate assembling of a casting mold in a method for constituting dividedly cores and assembling the mold by using expendable members for relative positioning of the cores. CONSTITUTION:A core for, for example, a cylinder block for an engine is trisected at the part corresponding to the intermediate bearing thereof to segmental cores 1-3 each having projecting parts 7 for fitting. A semicircular recess 9 for forming the above-described intermediate bearing part of the block is formed to the opposed surface 8 of each of the cores 1-3 when the cores are combined to face each other. Expendable members 4, 5 are formed to approximately the same shape as the shape of the part where a molten metal intrudes and which is formed when the cores 1-3 are combined to face each other. While the members 4, 5 are interposed in the mating surfaces of the cores 1-3, the cores 1-3 are successively superposed and combined to constitute an assembled core 12. The projections 7 of the cores 12 are then fitted into the fitting holes 16 of master molds 13, 14 and the upper master molds are combined therewith by which the casting mold is assembled.
