ABSTRACT:
A rotary plate is rotatably supported with respect to a stationary base using an R-guide, and the weight of the rotary plate and a mold mounted to the rotary plate is also supported by the R-guide in addition to a bearing. Therefore, a moment and a vertical downward load acting on the bearing of the rotary plate can be reduced. A block of the R-guide is fixed with respect to the rotary plate side through a disc spring. Therefore, while the rotary plate is rotating, the elastic force of the disc spring causes the rotary plate to separate from the stationary base by a space, which reduces the rotational resistance of the rotary plate. During mold clamping, respective pressure-receiving surfaces of the rotary plate and the stationary base contact each other against the elastic force of the disc spring, which enables reliable transfer of a mold clamping load to the stationary base.
