  • Patent number: 4261413
    Abstract: A foundry molding system for molding and closing cope and drag molds includes a linear idler molding line conveyor adjacent a cooling conveyor. Short powered sections are provided at each end of the molding line conveyor for set-off from the cooling conveyor to form the assembled cope and drag flasks into horizontally abutting drag and cope sets on the molding line conveyor and for closing and setting on the cooling conveyor the assembled cope and drag molds. Reciprocating index and control means are provided at each end of the molding line conveyor for indexing the sets therealong in abutting relationship. Powered roller detents or locaters are provided along the conveyor to hold the flasks to separate, center and retain the flasks for a variety of operations such as set-down, molding, drag rollover, coring, closing and set-on. The roller detents at the drag rollover are located in the trunnions of the rollover for operation therewith.

  • Patent number: 4248290
    Abstract: A foundry molding machine of the horizontal stack type such as shown in Hatch U.S. Pat. No. 3,958,621 employs a programmable solid state electrical control system operating in conjunction with a closed-loop hydraulic servo-system to obtain greater flexibility of set-up and higher mold uniformity and precision with fewer reject molds. Each of four of the major moving components of the machine may be provided with an encoder or position, velocity and direction monitoring device, such components being the two opposed squeeze rams, the mold traction device, and the pusher. Such monitors not only measure the final position of one squeeze ram, but also enable the calculation or measurement of the mold thickness so that the pusher cylinder can be controlled during its movement to contact a formed cake at a null condition and to move that cake into contact also at a null condition with a horizontally formed stack.

  • Patent number: 4230308
    Abstract: A heated ladle provides a reserve of molten metal. Vertical closing rods release desired quantities into pouring troughs. These are indexed into alignment with the mold casting orifices. The system includes a chassis movable parallel to the step-by-step movable casting line, a mobile cart carried by the chassis and also movable parallel to the line, and trough-bearing means movable perpendicularly to the line and also providing pivotal movement capability for the troughs. Reference marks on the molds or inter-mold spaces cooperate with position sensors to control the indexing. Redescent and resulting closing of the closing rods is automatic.

  • Patent number: 4205717
    Abstract: A plurality of carriages, each containing a pouring ladle, are provided for pouring molten metal into moving molds of a conveyor. The carriages are essentially driven from a single motor and move in a closed loop containing a loading zone and a pouring zone. Each carriage contains a clutch pump to control movement along the loop. Rotation of ladles to a pour position is attained by use of a parallelogram linkage on the carriage and remotely located variable pour rate controls. A sensor system including an extension arm is supported by each carriage for sensing the presence of a mold car and for causing the carriage to match the speed of the mold.

  • Patent number: 4200139
    Abstract: A process relating to the pouring of ferrous metal into a permanent mould made of iron or other like material, automating said moulds within the system so as to offer diversification of production and while so doing having a finished product that is of a machinable and marketable nature. Slow cooling of the castings through the critical temperature in the system limits the formation of iron carbides and successfully produce a machinable product.

  • Patent number: 4180120
    Abstract: A novel "cast-on" method and apparatus are disclosed wherein in the preferred embodiment only one major moving part is provided which is indexed through various positions to cast a group or element from a battery plate stack engaged thereby. In the preferred embodiment, a mold carriage block having a plurality of mold voids formed therethrough slidingly reciprocates along a base plate on which are defined fluxing (loading), casting and part-release positions. In the casting position, lead gravitationally siphons into the mold voids defined in the mold carriage through molten lead supply orifices defined in the base plate along which the carriage slides. Once the casting operation is completed, sliding the carriage out of the casting position effectively seals the molten lead supply orifices. The apparatus and method are particularly suited for use by a single operator who manually loads stacks into the apparatus and subsequently unloads completed groups or elements from the apparatus.

  • Patent number: 4180156
    Abstract: A device for handling flaskless moulds relates to foundry equipment and can prove to be most advantageous for use in automatic lines for flaskless horizontal-stack moulding. The device of this invention comprises a stationary bed adapted for arranging moulds, and a mechanism or gear for moving the moulds assembled into a stack. The gear is made as two sprocket endless chains running from both sides of the stationary bed concordantly thereto and carrying grips for retaining a stack of flaskless moulds during its travel along the stationary bed. The top horizontal portions of the chains are provided with guides adapted to draw these portions together above the bed. As a result, smooth bringing of the grips to and from the stack is performed.

  • Patent number: 4150705
    Abstract: When an empty molding box arrives at the molding machine on a roller track extending through the machine, it is placed on a pattern plate carrier with a pattern situated thereon and is lowered thereon on to a transverse roller track on which it is transferred, by means of a thrust drive operating on the carrier, to the empty station of a two-station transporting carriage on which it is then moved, by means of another thrust drive operating on the carriage, to one of the two outer working stations of a three-station roller track, namely a preparation track, parallel to the first-mentioned roller track, where the preparation work is done. As the two-station carriage moves thus, an already prepared molding box and carrier on its other station arrives at the central station of the preparation track and is then drawn back to the molding machine.

  • Patent number: 4074749
    Abstract: Disclosed is a casting machine which includes a truck driven horizontally in an advancing direction. A plurality of molds are carried on the truck. The molds are aligned in the advancing direction and are rotatable about axes extending perpendicular to the advancing direction. Each mold has a rearwardly extending lip which overlaps the forward edge of the next succeeding mold when the molds are horizontally arranged. Arms are connected to each of the molds for rotation therewith. The arms have wheels thereon which cooperate with guides adjacent to the path of travel of the truck in the advancing direction to control the rotational attitude of the molds. The aforesaid guides have horizontal sections which maintain the molds in a horizontal attitude, and curved sections which rotate the molds about their respective axes in order to discharge the contents thereof at a casting discharge position.

  • Patent number: 3977461
    Abstract: A continuous mechanical iron pouring line for pouring molten metal into a moving conveyor line of abutting sand molds. A plurality of pouring ladles mounted on independently driven and controlled carriages move along a track in a closed-loop between: (1) a stationary ladle filling station wherein molten metal flows from a stationary holding vessel into the ladle; (2) a pouring station wherein the molten metal is conveyed from the ladle into an associated moving mold as the ladle and mold move together through the pouring station; and (3) back to the filling station. Control of each carriage is effected by interaction of that carriage with preceding and succeeding carriages. At the pouring station, the mold line parallels the track along which the carriages move and defines a sector wherein the metal may be poured.
