Foundry molding system

Apparatus for producing foundry molds comprising a linear conveyor, a cope and drag flask set-off at one end of said conveyor operative to place the drag and the cope on such conveyor to form a horizontally abutting cope and drag set in line with previously formed sets supported by said conveyor thereby forming a row of flask sets, index means and control means at opposite ends of said conveyor, said index means operative to push such set and previously formed sets along the conveyor against said control means to maintain the sets in abutting relation, said control means yielding to said index means at a controlled rate for controlled movement of said sets, and a plurality of detent means being spaced apart sufficiently along said conveyor and cooperating with such cope and drag flasks at a plurality of stations along said conveyor to position and slightly separate adjacent flasks in such row of flask sets for at least molding, drag rollover, coring and closing, whereby such flask sets may be indexed intermittently along the conveyor in abutting relationship, said detent means including opposed sets of rollers cooperating with receptacles in the sides of the flasks, said rollers being journalled for rotation about a vertical axis on the ends of rods of piston-cylinder assemblies, and means to keep said rods from rotating.

Apparatus for producing foundry molds comprising a conveyor, a cope and drag flask set-off at one end of said conveyor operative to place the drag and the cope on such conveyor to form a horizontally abutting cope and drag set, index means operative to index such set and previously formed sets along the conveyor in abutting relation a distance slightly more than the horizontal length of a set, and a plurality of detent means along said conveyor cooperating with such cope and drag flasks at a plurality of stations along said conveyor to position and slightly separate such flasks for at least molding, drag rollover, coring and closing, whereby such flask sets may be indexed intermittently along the conveyor in abutting relationship, said detent means at the drag rollover comprising trunnions for a rollover frame whereby said detent means at the drag rollover positions a flask in said rollover frame and defines the rollover axis about which said frame is inverted.

A foundry molding system comprising a linear idler conveyor operative to support a row of cope and drag flask sets for horizontal movement therealong, said conveyor including a center point, a plurality of locaters on said conveyor at certain spaced locations therealong on opposite sides of said center point, and index means and control means at opposite ends of said conveyor operative to index such sets therealong a controlled distance until the approximate center of such row of sets is at said center point, said locaters being spaced apart sufficiently to separate adjacent flasks in such row of flask sets, and the locaters on one side of the center point moving the flasks on the same side in one direction while the locaters on the other side separate the flasks on such other side in the opposite direction, such movement of the flasks being progressively greater the further the flasks are from the center point.

A foundry molding system comprising an idler roller linear conveyor operative to support cope and drag flask sets for horizontal movement therealong, index means at one end of said conveyor operative to index such sets therealong in abutting relationship a distance slightly more than the horizontal length of a single set, and locater means on said conveyor operative to center and separate such flasks at certain locations along said conveyor, alternately with the operation of said index means, control means at the other end of said conveyor against which such flasks are pushed by said index means whereby such sets can be closely controlled to keep the flasks abutting and together moving at a controlled rate during indexing thereof, and foundry flasks adapted to be moved along said conveyor, each flask including a centrally located centering receptacle, and said locater means including a laterally movable locater operative to engage said flask at said receptacle to center and retain the same at a given location along said conveyor, said flask including top and bottom lateral flanges, said receptacle being formed by circular section rods extending between said flanges, the spacing between said rods being less than the width of said locater.

A foundry molding system comprising an idler roller linear conveyor operative to support cope and drag flasks sets for horizontal movement therealong, index means at one end of said conveyor operative to index such sets therealong in abutting relationship a distance slightly more than the horizontal length of a single set, locater means on said conveyor operative to center and separate such flasks at certain locations along said conveyor, alternately with the operation of said index means, control means at the other end of said conveyor against which such flasks are pushed by said index means whereby such sets can be closely controlled to keep the flasks abutting and together moving at a controlled rate during indexing thereof, and foundry flasks adapted to be moved along said conveyor, each flask including a centrally located centering receptacle, and said locater means including a laterally movable locater operative to engage said flask at said receptacle to center and retain the same at a given location along said conveyor, said locater being a laterally movable roller, and the sides of each flask including a linear cam for said roller fore and aft the receptacle.

Apparatus for producing foundry molds comprising a linear conveyor, a cope and drag flask set-off at one end of said conveyor operative to place the drag and the cope on such conveyor to form a horizontally abutting cope and drag set in line with previously formed sets supported by said conveyor, index means and control means at opposite ends of said conveyor, said index means operative to push such set and previously formed sets along the conveyor against said control means to maintain the sets in abutting relation, said control means yielding to said index means at a controlled rate for controlled movement of said sets, a plurality of detent means along said conveyor cooperating with such cope and drag flasks at a plurality of stations along said conveyor to position and slightly separate such flasks for at least molding, drag rollover, coring and closing, whereby such flask sets may be indexed intermittently along the conveyor in abutting relationship, a frame straddling said conveyor, a reciprocating carriage mounted on said frame to and from a position over said conveyor, an elevator mounted on said carriage, a drag pick-up mounted on said elevator, a cope pick-up mounted on said frame and vertically aligned with said drag pick-up in a position of said carriage over said conveyor, and means to move said cope pick-up vertically independently of said elevator.
