Abstract: 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.

Abstract: A mould tool is disclosed, for use in repairing the eroded leading edge of a wind turbine blade. The mould tool comprises a flexible sheet and a framework which is flexible in one direction, for conforming to the curved edge of the blade, but rigid in the other direction. The mould tool may include tapered side walls. Preferably, a method or repair involves use of a mould tool with tapered side walls, and use of a similar mould tool which lacks the tapered side walls. To repair a section of the edge of a turbine blade, first stripes of resin are injected, spaced apart along the length of the section, using the mould with side walls. The gaps between the stripes are then filled using the mould without side walls.

Abstract: Provided is a resin molding apparatus that can suppress a molding problem caused by a variation in a thickness of an object to be molded or suppress a variation in a thickness of a resin molded part, and can perform a mold releasing operation. A resin molding apparatus includes: a molding mold having one mold and the other mold; one mold wedge mechanism; and one mold cavity block driving mechanism. In a state that a height position of one mold cavity block is set using the one mold cavity block driving mechanism and a position in a direction away from the other mold in the one mold cavity block having been moved to the height position is fixed to be limited using the one mold wedge mechanism, a mold releasing operation can be performed using the one mold wedge mechanism and the one mold cavity block driving mechanism.
