PROBLEM TO BE SOLVED: To provide a metallic mold set obtaining good yield of a product in an injection-forming of molten metal. SOLUTION: A second runner part C provided with a hollow part having sufficient depth to the height direction of a gate 21 having a gap of about 1 mm height and extended along the longitudinal direction of a cavity D together with the gate 21, plays a part, in which the molten metal made to flow in from a first runner part B is temporarily stored. By this constitution, the flow-front of the molten metal in the cavity D is stabilized. |
