Abstract: In a tilting gravity casting apparatus, a die includes a ladle that stores a molten metal and the molten metal is poured through a runner into a cavity of the die when the die is tilted. The apparatus includes a block member for blocking the runner, a pressing pin for pressing the molten metal in the cavity, a controller that controls operation of driving the block member and the pressing pin, and a first molten metal sensing sensor disposed in the runner. The controller is configured to start driving the block member and the pressing pin based on a detection signal outputted from the first molten metal sensing sensor.

Abstract: A tilting gravity casting apparatus, a die includes a ladle that stores a molten metal and the molten metal is poured through a pouring gate into a cavity of the die when the die is tilted. The cavity accommodates a cylindrical protrusion for forming a closed-end hole in a bearing support portion of a knuckle, and the cavity has a pressing boss portion located along an axial line of the cylindrical protrusion. Before a die tilt step of tilting the die is completed, a press step of pressing the molten metal in the pressing boss portion by using a pressing pin and a pouring gate block step of blocking the pouring gate with a block member are initiated.
