PROBLEM TO BE SOLVED: To provide a low-pressure casting furnace capable of preventing a foreign matter such as an oxide from being taken into a die.;SOLUTION: The low-pressure casting furnace 10 includes a holding furnace 24 for holding molten metal M, and a pressurization furnace 12 communicated with the holding furnace 24 by an openable and closable molten-metal flow port 28. The pressurization furnace 12 includes a pressurization chamber 14 for storing the molten metal M, a filling stoke 18 for filling the molten metal M stored in the pressurization chamber 14, into the die 20, and a pressurizing stoke 16 for pressurizing the molten metal M stored in the pressurization chamber 14, and a lower end 18a of the filling stoke 18 and a lower end 16a of the pressurizing stoke 16 are arranged in a side lower than a face of the molten metal stored in the pressurization chamber 14.;COPYRIGHT: (C)2012,JPO&INPIT
