Abstract
A lock assembly for releasably coupling a platen to a tie bar of an injection molding machine includes first and second lock nut segments translatable in a transverse between locked and unlocked positions for respectively engaging and disengaging the tie bar, and a carrier assembly for coupling the lock nut segments to the platen. The carrier assembly provides a slide surface for slidably supporting the lock nut segments during the translation of the lock nut segments between the locked and unlocked positions, and the carrier assembly resiliently supports the slide surface for axial movement of the slide surface with the lock nut segments between an unloaded position in which the lock nut segments are spaced away from the platen by a clearance gap, and a loaded position in which the lock nut segments bear against the platen.
