Abstract
Four cavities are arranged on a concentric circle 'C' with respect to the center 'O' of a flow divider and a gate sleeve. Each of the cavities is connected to a sleeve stamp portion through each of four die side runners and each of four stamp side runners formed in a radial direction and separated from the neighboring runners. A semicircular arc-shaped reservoir is provided between the lower half side of the flow divider and the lower half side of the gate sleeve. This reservoir is connected to the sleeve stamp portion. A semi-solidified layer formed by pouring the molten metal into a sleeve is filled into the reservoir, so that the molten metal from which the semi-solidified layer is separated can be filled directly from each of the stamp side runners via the die side runners into each of the cavities evenly and simultaneously.
