Feed device for a pressure die-casting or injection machine

A feed device for an injection chamber of a pressure die-casting or injection machine or for a press tool or a forging press die, and for transferring a billet of metal, whether filled or unfilled, in a liquid, solid, semi-solid or semi-liquid state, and which has a support with a horizontal axis, said support receiving and housing the billet and transferring the billet into the injection chamber or into the press-die, wherein, said billet support being positionable in at least one heating system, and includes a tube for receiving said billet, said tube being fitted into a cylindrical metal piece, with interposition of seals so as to hold said tube tight in said cylindrical piece, said cylindrical piece being mounted on a pneumatic ram which imparts to said tube a rotational about a cylindrical axis of motion said tube, said pneumatic ram being mounted on an end of a pneumatic translational ram imparting to the tube a to-and-from translational motion along said tube axis, said rams transporting the billet from a heating position in said heating system to a position lying vertically above the injection chamber or the press die, and then rotating said tube so as to cause the billet to drop, horizontally under gravity, from said support into said injection chamber or into the press-die.
