In this method, prior to closing the mold, a cylinder sleeve set diagonally from below is held with a fall prevention pin, and when the mold is closed, this cylinder sleeve is held with a core provided in the other mold, and the cylinder sleeve is held in place to prevent it from falling. Since the lower end of the prevention pin is not exposed to the inside of the product cavity, it is possible to reliably prevent the cylinder sleeve set from diagonally below the mold from falling before and after the mold is closed, and to avoid unnecessary holes in the casting. It is possible to prevent this from occurring, thereby simplifying post-processes and maintaining high product quality.
