摘要： A casting rollover apparatus includes a cage supporting a casting mold and a slide coupled to the cage for advancing the mold into and out of engagement with a molten metal discharge nozzle. A spindle is carried on the slide and coupled to the cage for rotating the cage. A clamp cylinder is carried on the cage for clamping the mold in the closed position. A single transducer is mounted on one of a pair of pressurized fluid drive cylinders on the slide to detect the position of the slide. Electrical plug connectors are coupled to the transducer and the cylinder control elements. Thrust bearings are mounted on the spindle and apply a pre-load to the spindle. A digital proportional valve is coupled to a drive cylinder for controlling the deceleration of the spindle. A position detector switch is mounted in the path of angular rotation of the spindle to initiate spindle deceleration. The clamp cylinder carries a tubular member coupled to the piston and movable with respect to the clamp cylinder housing. An end of the tubular member is formed as a scrape surface to remove debris from the sidewall of the clamp cylinder.
