The molding press has longitudinal rails along the top thereof parallel to the direction of relative movement of the platens. There is an elongated horizontal gantry structure supported solely by the press and movably secured to the rails with the longitudinal axis of the gantry structure being oriented normal to the rails and the gantry is movable along the rails. There are two arms, one of which depends from one end of the gantry and the other depends from the opposite end of the gantry, and these arms are movably secured to the gantry for back and forth movement along the longitudinal axis of the gantry. There is a load carrier secured to one of the arms and an unload carrier secured to the other arm, each load and unload carrier being movable with the respective arms. The two arms are movable toward each other when the mold is open to position the load carrier and unload carri…
