ABSTRACT Mould closing apparatus for an injection moulding machine having at least one injection mould, comprises first and second injection mould halves displaceable respectively on a first fixed plate 11 and a mould carrier plate 13 which is moveable on at least two rails 14 extending between the first fixed plate 11 and a second fixed plate 12. Displacement is effected by means of at least one long-stroke moving cylinder and piston device for rapid opening and closing of the mould halves, and a high pressure short-stroke pressure cushion device for closing the injection mould halves under high pressure. The piston 16 of the pressure cushion device is annular with at least one recess in its inner surface. A rod 17 is fixedly connected to the moveable mould carrier plate 13 and is axially moveable in the annular piston 16. The rod 17 carries a multiplicity of coupling members in the form of spreader flaps 26 which are pivotable into and out of the recess of the annular piston.
