A sand-forming apparatus () comprising a sand magazine (), a manifold (), a core box () defining a cavity (), a clamp table (), and a blow tube assembly (). The apparatus () is convertible from a sand-blowing state to a catalyst-introducing state without removal of the blow tube assembly () and/or un-clamping of the tool package (e.g., the manifold () and the cope/drag halves of the core box ()). In the sand-blowing state, sand is blown from the magazine () into the cavity () and, in the catalyst-introducing state, the catalyst is introduced into the blown sand in the cavity () to solidify the sand into a sand-shape. Molten metal can be poured into or around the sand-shape formed by the apparatus () and, upon completion of casting the metal part, the sand-shape can be removed.

A sand-forming apparatus () comprising a box (), a blow tube assembly () and a bonnet (). The box () has a cope () and a drag () which together define a cavity () having a shape corresponding to a desired sand-shape. The blow tube assembly () comprises a blowplate (), and at least one tube (). The bonnet () may be fixed to and movable with the blowplate (). Relative movement between the cope (), the blowplate () and/or the bonnet () converts the apparatus () between a sand-blowing state and a catalyst-introducing state.

A foundry core blowing machine includes an upright frame with a blow head for a sand-resin mix fixed at the top. Sectionalized vertically movable rods extend through bushings at the top and bottom of the frame. Fixed to the rods are a cope support and a secondary table. The secondary table supports the cylinder of a cope-drag clamp piston-cylinder assembly with the rod of such assembly being connected to a primary table thereabove which slidably moves on the rods. The secondary table and the rods secured thereto are elevated independently of the cope-drag clamp so that the clamped cope and drag may be elevated to be clamped against the blow head, lowered for interposition of a cure head, and reclamped for cure, all while the cope and drag remain firmly clamped together. Only after curing are the cope and drag unclamped for lowering, stripping and removal of the core from the machine. The continuous high pressure clamp of the drag to the cope during blow and subsequent cure, even though the assembly is unclamped from the blow head prevents sand from entering between the abutting surfaces of the cope and drag and the forming of finning.
