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.
