A cope for a core box has a passage for passing sand into a core box cavity and a bore for passing catalyst into the core box cavity to harden a sand core formed therein. The bore may extend from an exterior surface of the cope to the cope passage. The cope may have structure for forming a seal with a sand injection tube following sand injection, such as a blow-up seal or an O-ring. A method of producing cores in a core box includes the step of providing a cope, a drag, and a cavity formed therebetween, the cope having a passage for receiving an injection tube and a bore for passing catalyst. Further steps include using the injection tube to inject sand through the cope passage into the cavity and passing catalyst through the bore in the cope into the cavity. A seal may be formed between the cope and the injection tube after sand injection.

Cope with bore for gassing cores

The injection tube for injecting and gassing of foundry sand in cavities in a core box has a first passage for passing sand and a second passage for passing hardening fluid. Sand may be injected simultaneously to the introduction of hardening fluid into the cavities. Alternatively, sand may be injected prior to introduction of hardening fluid into the cavities.

Apparatus and methods for injecting and gassing of sand

A core box assembly for molding cores includes a first core box and a second core box disposed above the first core box. Each of the core boxes has a cavity. A passage for delivering core material to the cavities in the core boxes extends through the second core box and into the first core box. The second core box is placed above the first core box and core material is injected into the core boxes.

Apparatus and method for producing multiple cores

The core box includes a cavity therein, a vent in fluid communication with the cavity, ejector members, and apparatus coupled to the ejector members for passing a fluid through the vent into the cavity.

Apparatus and method for cleaning core box vents

A handling apparatus for a core molding machine is capable of moving a core box portion between a molding position and an eject position using only a single actuator. A carriage carries a platen that supports a core box portion wherein the platen is rotatable about a pivot axis relative to the carriage. The platen carries a roller that rolls on a cam surface adjacent the carriage. As the carriage is retracted away from a molding position, the roller rolls over the cam surface and permits the platen to pivot relative to the carriage downwardly toward the eject position.

Core box handling apparatus for a core molding

An improved core making machine having a frame and capable of producing cores at a molding position within the frame is easily configured to include one or more horizontal core box handling components and/or one or more vertical core box handling components. The machine is readily adaptable to many different foundry needs.

Modular core making machine

A core box shuttle system includes a shuttle car movable along a path, a movable shaft, a guiding surface carried by the shuttle car having a longitudinal extent transverse to the path and a slip-type connection between the movable shaft and the guiding surface whereby movement of the movable shaft is converted by the slip-type connection into movement of the shuttle car along the path.
