ABSTRACT OF THE DISCLOSURE This invention relates to hydraulic actuating mechanism for a valve gated injection molding system wherein the enlarged head of the valve pin is removably connected to the piston and a floating seal is provided against the leakage of hydraulic fluid. The actuating mechanism has a piston which is reciprocated in a cylinder between open and closed positions. The valve pin extends through a bore in the piston and has an enlarged head which is retained in a cup in the piston by a circular cap which fits over it. The cap is held in position between a removable resilient retaining ring which snaps into a groove and a compressible O- ring. Thus, both a seal against leakage and an easily releasable connection between the valve pin and the piston are provided by the combination of the resilient retaining ring and the O-ring.
