    摘要: A mold clamping device includes: a fixed platen; a movable platen; a rotary platen provided on one platen of the fixed platen and the movable platen, to which a mold is attachable; and an extrusion device provided on the one platen and configured to extrude a molded article from the mold. The rotary platen is disposed at a side of a surface of the one platen facing the other platen to face the one platen and is rotatable via a bearing structure. The extrusion device is disposed on a surface of the one platen opposite to the surface facing the other platen. The bearing structure is configured to bear the rotary platen at a position away from a rotation center in a radial direction. The extrusion device has an ejector rod that protrudes radially inward than the bearing structure.

    摘要: The present invention relates to a position determining mechanism for a rotary platen. The rotary platen is disposed to face a mold platen and is provided to be rotatable with respect to the mold platen. The position determining mechanism includes a position determination part which is provided to one platen of the mold platen and the rotary platen, and a position determination driving mechanism which is provided to the other platen, in which the position determination driving mechanism includes a press member and a pressing device, and when the press member is pressed by the pressing device and the press member is fitted into the position determination part, a rotation position of the rotary platen is determined.
