  • Patent number: 8353328
    Abstract: A sand-forming apparatus (10) comprising a box (20), a blow tube assembly (50) and a bonnet (90). The box (20) has a cope (30) and a drag (40) which together define a cavity (21) having a shape corresponding to a desired sand-shape. The blow tube assembly (50) comprises a blowplate (55), and at least one tube (50). The bonnet (90) may be fixed to and movable with the blowplate (55). Relative movement between the cope (30), the blowplate (55) and/or the bonnet (90) converts the apparatus (10) between a sand-blowing state and a catalyst-introducing state.

  • Patent number: 7441583
    Abstract: A sand-forming apparatus (10) comprising a sand magazine (12), a manifold (14), a core box (16) defining a cavity (18), a clamp table (20), and a blow tube assembly (22). The apparatus (10) is convertible from a sand-blowing state to a catalyst-introducing state without removal of the blow tube assembly (22) and/or un-clamping of the tool package (e.g., the manifold (14) and the cope/drag halves of the core box (16)). In the sand-blowing state, sand is blown from the magazine (12) into the cavity (18) and, in the catalyst-introducing state, the catalyst is introduced into the blown sand in the cavity (18) to solidify the sand into a sand-shape. Molten metal can be poured into or around the sand-shape formed by the apparatus (10) and, upon completion of casting the metal part, the sand-shape can be removed.
