PURPOSE:To enable casting under high oscillation without reinforcing the frame part of a casting mold by supporting an actuator for oscillating the mold in a closed frame-shaped beam so that the inertial force of the mold is absorbed in the beam. CONSTITUTION:A casting mold 10 is attached to a closed frame-shaped beam 11 and an actuator 14 is disposed in the beam 11. The upper beam part 11A is oscillated by the exciting force of the actuator 14, by which the mold 10 is oscillated in the casting direction. The oscillation reciprocated with the upper beam part 11A is generated by the reaction of the actuator 14 in a lower beam part 11B. Even if the mold 10 oscillates at a high speed, the exciting force and inertial force generated by the oscillation are offset in the beam 11. The casting under high oscillation is thus made possible without reinforcing the frame part of the casting mold. |
