Abstract
A machine for forming foundry moulds includes a turret supporting spaced mould frames, each of the latter having a mould portion formed therein by rotation of the turret toward a sand filling and compacting station and away therefrom. The completed mould portion may be moved to a position where a core can be set thereon and then moved to a position where the mould portions are positioned one atop another to make a stack of finished and cored moulds. When the moulds are not cored, a pair of said filling and compacting stations are provided, the turret oscillating or rotating unidirectionally from a loading position to a delivery position. Where a pair of filling and compacting stations are provided for forming cope and drag mould portions, the turret oscillates to place the two mould portions in proper position to form a mould comprised of cope and drag portions. The machine makes foundry moulds capable of being placed one atop another, a pair of moulds defining a pouring lip connected to a pouring channel in turn connected to runners and mould cavities.
