Abstract
An injection molding apparatus is used for making parts having a hollow portion that is disposed under an angle relative to an axis. The molded parts are ejected when a movable stripper plate is displaced relative to the mold core used to cool the angled portion of the molded part. The stripper plate includes cooling channels and a cooling outlet. The cooling outlet is coupled to a cooling inlet of a movable cooling slider element. Leakage of a cooling fluid is prevented by using a sealing device and sealing elements between the cooling slider and a cooling manifold retaining the mold cores when the stripper plate is used during the ejection of the molded parts from the mold cores.
