PROBLEM TO BE SOLVED: To provide a molten material injection pump which can increase an injection speed of molten metal or the like without enlarging a device.SOLUTION: A molten material injection pump 1 comprises an injection rotor 10 which can rotate with a rotating shaft O as a center, and an injection rotor drive unit 30 for rotationally driving the injection rotor 10. The injection rotor 10 has an injection flow passage 11 which penetrates the injection rotor in the rotating shaft O direction, and in which molten metal flows. One end of the injection flow passage 11 is a flow-in port 11c into which the molten metal flows, and the other end of the injection flow passage 11 is an injection port 11d from which the molten metal is injected. A distance between the injection flow passage 11 and the rotating shaft O becomes long as progressing toward the injection port 11d side from the flow-in port 11c side, and a distance between the injection port 11d and the rotating shaft O is set longer than a distance between the flow-in port 11c and the rotating shaft O. The molten metal flows in the injection flow passage 11 toward the injection port 11d side from the flow-in port 11c side by the rotational drive of the injection rotor 10 by the injection rotor drive unit 30. |
