CAM ACTUATED EJECTOR MECHANISMS FOR PRESSES Abstract of the Disclosure A hydraulically actuated ejector mechanism is mounted on a press bed and includes a pair of opposed cams connected to the press slide for vertical displacement therewith. The cams actuate corresponding followers in the form of hydraulic pistons which operate together to hydraulically displace an ejector member during upward movement of the slide following a metalworking operation. The cam contours enable timing the ejector pin displacement with the press slide stroke so as to achieve optimum acceleration and deceleration of the stroke of the ejector pin.
