An injection molding machine comprises a first platen and a second platen, the first platen movable relative to the second platen in an axial direction between open and closed positions, and a plurality of tie bars extending generally between the first and second platens for coupling together the first and second platens. At least a first locking device is mounted to the first platen and associated with a first one of the tie bars for selectively locking and unlocking the moving platen relative to the tie bar. At least a first clamping mechanism is mounted to the second platen and associated with the first tie bar, the clamping mechanism including clamp and unclamp chambers on either side of a piston for moving the piston towards clamp and unclamp positions to exert a clamping force and a mold break force, respectively. The machine further includes a traverse actuator comprising one or more linear actuators coupled to at least one of the first and second platens for effecting said movement of the first platen relative to the second platen between the open and closed positions, the one or more linear actuators together being free of provision for applying a mold break force to the platens.
