Abstract
An securing/clamping assembly for clamping platens of an injection molding machine includes a mechanism for guiding the platens and a body member having a structure which is movable as a single unit. The body member is adapted to be attached with at least one of the platens and includes a mechanism for securing the mechanism for guiding and for conveying a clamping force to the platens for clamping the platens during injection molding. The mechanism for securing includes an engagement mechanism for placing the mechanism for securing into and out of locking engagement with the mechanism for guiding, such that when the engagement a mechanism is out of locking engagement with the mechanism for guiding, the body member and the mechanism for guiding are relatively movable.
