Summary:PURPOSE:To execute good quality casting by pouring molten metal from a crucible into a mold located in the casting space in a vacuum vessel while by successively lowering the mold. CONSTITUTION:The metal is melted in a crucible 12 for melting the metal in a vacuum vessel 1, and casting is executed by pouring the molten metal into a mold 22 while succesively lowering the mold. When the mold is lowered, the opening/closing lid is opened, a connection part 24 is operated from an opening part 25 and a solidifying plate 21 is separated from an elevating body 19, and the mold is taken out of the vacuum vessel through this opening part together with the solidifying plate. When casting is again executed, another mold 22 having a solidifying plate 21 is placed in the vacuum vessel from the opening part 25, and the solidifying plate is connected to the elevating body 19 by the operation of the connection part through the opening part, and then, the following casting can be started. This constitution allows casting of good quality, rapid starting of the following casting operation, and improves the operational efficiency.
