Abstract
A quick-change tie bar mechanism includes an actuator having a rod coupled to a first bearing member and a body coupled to a second bearing member. The first and second bearing members are configured to reciprocally move in opposite directions in response to extension and retraction of the rod relative to the body. The bearing members have a first configuration for engaging a nut threaded on a tie bar to fix the tie bar in relation to a platen through which the tie bar extends. The first and second bearing members also have a second configuration for releasing the tie bar to permit removal through the platen so that a part may be accessed for removal and/or replacement.
