PURPOSE: To mass-produce good ingots for a long period, by dividing a molten material from a container into numerous portions and pouring them into numerous molds simultaneously.

CONSTITUTION: When the cylindrical container 1 is swung and an opening 3 over partition walls 2 are connected to a molten material chamber 11, the molten material flows into the container 1 and is reserved in chambers 4 at a level restricted to the height of the molten material chamber 11. When the container 1 is swung back and the pouring ports 5 of the chambers 4 are located at the level of the molten material in the chambers, the molten material starts falling down into the molds 21 through the pouring ports 5. When the container 1 is swung back to the lowest position of the pouring ports 5, a prescribed quantity of the molten material in each chamber 4 is all poured into the mold 21.
