ABSTRACT:
A degassing apparatus for a mold includes a degassing valve, an acoustic wave detecting unit, and a valve closing unit. The degassing valve is located at an end portion of a degassing passage extending from a mold cavity. The acoustic wave detecting unit is arranged midway along the degassing passage and detects an acoustic wave generated when a molten metal collides against a wall surface of the passage, and thereby detecting passing of the molten metal. The valve closing unit closes the valve when a detection signal level is higher than a reference signal level.
