範囲第１項に記載されたダイカスト装置。[Claims for Utility Model Registration] (1) A method in which the cavity of a mold is filled with molten metal, and before the molten metal solidifies, a pressurizing rod is advanced into the cavity to apply secondary pressurizing pressure to the molten metal. In a die casting machine, a hole for a pressurizing rod formed through a mold wall has a peripheral portion of the opening end facing into the cavity formed as an inclined surface where the hole diameter increases toward the cavity side, and the opening for the pressurizing rod is A die-casting device characterized in that the periphery of the tip is chamfered to form an inclined surface with a reverse slope corresponding to the inclined surface. (2) The utility model registration claim 1 is characterized in that the inclined surface around the opening end and the inclined surface around the tip of the pressure rod have the same height in the direction of advance and retreat of the pressure rod. The die casting device described in item 1.
