    摘要： An automated matchplate molding machine includes a cope flask, a pattern plate and a drag flask for creating formed sand molds. The mold machine incorporates linear-motion slides and/or rodless cylinders to move the cope flask, drag flask, sand hopper, and/or other components of the mold machine.

    摘要： The drag flask has at least two opposed sides which include recesses proximate the matchplate. Manifolds are provided in the recesses to communicate compressed air from a source of compressed air to air inlets provided in the manifold. The manifolds are separated from the recesses using an elastomeric seal which is contoured to direct the compressed air between an air passage disposed between the drag mold and the matchplate. When incorporated into a sand mold forming machine, sensors are positioned on the sand mold forming machine to detect when the drag flask has reached a releasing position to thereby cause the source of compressed air to inject air into the manifold and air passage for release of the drag mold from the drag flask.

    摘要： In an improved method and apparatus for investment casting, a pattern (31) is mounted on a sprue base (19) of an spider gasket (12) that is secured to one end of a standard investment flask (11). A solid end cap (13) is secured to the other end of the flask. The end cap is provided with a matrix of holes (15) extending therethrough parallel to the axis of the flask, and a plurality of small diameter rods (16) are slidable secured in the holes in the end cap. The rods are extended into the interior of the flask about the pattern without contacting the pattern. Investment plaster (10) is poured into the flask through the spider assembly to immerse the pattern and rods, and the plaster is allowed to set. The rods are then withdrawn, forming a large plurality of channels (32) extending into or through the investment plaster, reducing the amount of investment plaster required in the flask. The channels greatly accelerate the drying time of the investment, and hasten the subsequent burnout process in a kiln. The channels permit the escape of air from the cavity during casting, so that casting porosity is eliminated. Moreover, the channels formed by the rods are ideally placed for the strategic application of vacuum to the mold cavity during casting.

    摘要： A mold box for use in the molding of shell or stack molds comprises a pattern frame having internal lining strips that are detachably secured to the inner side walls of the pattern frame to constitute the sides of the molding space in the box. A movable pattern plate constitutes the bottom of the molding box and means are provided for moving the pattern plate into engagement with the lower edge of the lining strips so that the depth of the molding space in the box is determined by the width of the detachable lining strips.

    摘要： The mold forming apparatus includes a flask, upper and lower pattern plates, a chute for disposing molding medium into the mold chamber formed by the flask and lower pattern plate, and a plurality of fluid actuated cylinders for raising the flask and lower pattern plate to compress the molding medium against an upper pattern plate, and for displacing the completed mold through the flask to an elevated position. The flask includes a shoulder portion along its opposite sides and intermediate its open ends for forming a complementary shoulder portion about the side edges of the mold. When the mold is elevated above the flask, support fingers engage the shoulder portion of the mold for supporting the latter.
