Abstract
A low-pressure casting device is provided with a holding furnace, a stoke, a pressure control device and a molten-metal level sensor. The holding furnace holds molten metal. The stoke supplies molten metal into a casting mold via a sprue. The pressure control device moves the molten metal in the stoke and fills the molten metal in the casting mold. The molten-metal level sensor detects a surface level of the molten-metal in the stoke. The stoke has a lower end immersed in the molten metal in the holding furnace. The low-pressure casting device is configured to correct filling of the molten metal in the casting mold in a next casting based on the height of the molten metal surface detected by the molten-metal level sensor.
