Abstract
A first drive means is provided to an upper turret and a lower turret in such a manner as that the upper turret and lower turret can be synchronously rotated through a turret drive system, and a second drive means is provided to an upper metallic mold and a lower metallic mold in such a manner as that the upper and the lower metallic molds can be synchronously rotated within the respective turrets through a metallic mold drive system, and the metallic mold drive system is connected to the turret drive system through a differential gear mechanism. And, when the turrets are positioned, the second drive means is held stopped and the metallic molds each holding its own dividing angle are rotated within the respective turrets by the first drive means through the differential gear mechanism. The dividing of the angles for the respective metallic molds is carried out through the differential gear mechanism by the second drive means while maintaining the turrets positioned and stopped.
