Abstract: 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.
