Definitions

  • ABSTRACT A matchplate foundry molding machine having a fill station and an adjacent molding station with a cope, matchplate, and drag assembly adapted to be indexed between such stations.
  • the assembly in the fill station is supported for inversion so that the drag may be inverted and filled with sand.
  • After a bottom board is inserted the assembly is reinverted and the cope filled with sand.
  • the assembly is then indexed into the molding station which includes a vertically movable table, a drag support, a cope support, a fixed matchplate support, and a squeeze head incorporating a jolt ram.
  • the table elevates and simultaneously jolts and squeezes the cope and drag.
  • the table is then lowered to draw the matchplate from the cope which is held against the squeeze board by its support and when the drag and matchplate reach the matchplate support, the matchplate is drawn from the drag with the drag continuing to coring height with the matchplate alone now indexing back to the fill station.
  • the drag support then elevates the drag with the table following to close the drag against the cope, slight further elevation lifting the flasks free of the sand cakes held by the squeeze head which are then supported on the table.
  • the table lowers with the booked cope and drag sand cakes thereon, the drag support following with the drag, with the cope remaining elevated.
  • the matchplate is again indexed into the molding station to be reassembled with the cope and drag flasks.
  • the assembly is then indexed to the fill station for filling and the booked cand cakes are pushed out of the machine.
  • This invention relates generally as indicated to a matchplate foundry molding machine and more particularly to a machine of the type noted which is compact and of simplified operation.
  • Matchplate molding machines generally include a fill and molding station together with a closing station. In order to accomplish both fill and molding at the same station, it is normally required that the molding or squeeze head he laterally shiftable to clear the flasks therebelow for filling or that a sand measuring box be indexed into position for filling in the molding station. This generally requires either a horizontally movable squeeze head or a horizontally movable sand metering box or both. Examples of such matchplate molding machines may be seen in U.S. Pat. No. 3,589,432 to Miller et al. and Hunter U.S. Pat. No. 3,406,738.
  • the tooling includes the matchplate which incorporates both the cope and drag patterns as well as the squeeze head which may imprint a pouring basin on the cope portion of the sand cake.
  • both the matchplate and the squeeze head may be quickly changed.
  • the present invention also provides a matchplate molding machine which utilizes a jolt mechanism in the squeeze head, the latter being vertically stationary and thus avoiding the complexities attendant to providing a jolt mechanism in the vertically movable squeeze table.
  • the present invention provides a matchplate molding machine wherein the cope and drag are filled at one station and then moved to an adjacent molding station, the cope and drag being rammed at the molding station with the matchplate then being drawn first from the cope and then the drag, the latter being booked with the flasks lifted therefrom to form a booked cope and drag sand cake, the thus formed mold then being pushed from the molding station after the cope and drag flask is reassembled with the matchplate to be shifted to the fill station for filling.
  • Another important object is the provision of a compact matchplate molding machine utilizing adjacent fill and molding stations, the sand cakes being rammed, drawn, stripped and closed at the latter.
  • a further important object is the provision of a matchplate molding machine utilizing at the molding station unique cope and drag support means controlling the position of the cope and drag flasks following molding to obtain drawing, booking, stripping and reassembly.
  • a further object is the provision of a matchplate molding machine utilizing a fill station having sand fill apparatus which can quickly fill the drag and then the cope with measured amounts of sand.
  • Still another object is the provision of a matchplate molding machine utilizing a simplified hydraulically operated table to receive the sand filled cope and drag flasks and to ram the sand therein.
  • Yet another object is the provision of a matchplate molding machine utilizing a squeeze head incorporating a jolt ram therein.
  • a still further object is the provision of a matchplate molding machine utilizing a cope support permitting the cope to move upwardly but not downwardly until released for reassembly.
  • a yet further object is the provision of a matchplate molding machine having an improved matchplate indexing mechanism which operates during the cycle of the machine to index the matchplate both with and without the cope and drag flasks.
  • FIG. 1 is a side elevation of a machine in accordance with the present invention
  • FIG. 2 is a front elevation of the machine with the table operating piston-cylinder assembly and the squeeze head partially broken away and in section as seen from the line 2-2 of FIG. ll;
  • FIG. 3 is a rear elevation of the machine as seen from the line 3-3 of FIG. 1;
  • FIG. 4 is a vertical section taken through the fill station of the machine as seen from the line 4-4 of FIG.
  • FIG. 5 is an enlarged elevation of the draw mechanism of the machine with one of the draw cylinders being shown in section;
  • FIG. 6 is an enlarged elevation of the bottom board feeding mechanism as seen in FIG. 4;
  • FIG. 7 is a top plan view of such bottom board feeding mechanism as seen from the line 77 of FIG. 6;
  • FIG. 8 is a fragmentary enlarged end view of the bottom board feed mechanism
  • FIG. 9 is an enlarged end elevation of the matchplate indexing and carriage inversion mechanism
  • FIG. 10 is an enlarged side elevation of the matchplate indexing and carriage inversion mechanism partially broken away and in section;
  • FIG. 11 is an enlarged end elevation of the matchplate indexing piston-cylinder assembly
  • FIG. 12 is an axial section of such piston-cylinder assembly taken substantially on the line ll2-l2 of FIG. 11;
  • FIG. 13 is a fragmentary section taken substantially on the line 13-13 of FIG. 11;
  • FIG. 14 is a fragmentary top plan view of the mechanism shown in FIG. 10 as seen from the line ll4l4l thereof;
  • FIG. 15 is an enlarged vertical section of the cope support mechanism
  • FIG. 16 is a horizontal section taken substantially on the line 16-16 of FIG. 15;
  • FIG. 17 is an enlarged top plan view of the squeeze head
  • FIG. 13 is a quarter section of the sqeeze head taken substantially on the line l18]l8 of FIG. 17;
