A foundry core or mold machine utilizes a horizontally extending frame pivoted at one end which fixedly supports one box half or cope and movably supports the other box half or drag. A power actuator pivots the frame to clamp the box halves closed against a blow head or gassing head which may be shuttled thereabove. The drag box half is mounted on a cradle on the frame for movement toward and away from the cope or fixed box half and for pivoting movement to bring the box to a core or mold discharge or an inspection or disassembly position when the box halves are not clamped against the blow head or gassing head. Each box half includes a machine actuated stripping mechanism to insure removal of the core or mold both from the cope and drag with the latter then placing the core on a discharge conveyor. The conveyor may be of the flat belt type canted slightly to present a flat surface to receive the core or mold.
A foundry core or mold blowing machine comprising a blow head, a pivoting frame, separable mold halves supported for closing and for separation on said pivoting frame, and means to pivot said frame in one direction to clamp such halves when closed against said blow head, said frame extending generally horizontally and pivoted at one end.
A foundry molding machine comprising a stationary cope and movable drag, a horizontally extending vertically movable frame pivoted at one end supporting said cope and drag, means on said frame to clamp the cope and drag together on a generally vertical parting plane for filling with sand, and means on said frame to separate the cope and drag and pivot the drag when separated.
A foundry machine as set forth in claim 40 including a sand fill chute for said blow head, said blow head being positioned beneath said chute when said gassing head replaces said blow head.
A foundry core blowing machine comprising a blow head, a generally horizontally extending frame transverse of said blow head and pivoted at one end offset from the axis of said blow head, core box halves mounted on said frame, and means to pivot said frame toward said blow head to clamp the core box halves thereagainst.
A foundry blow molding machine comprising a blow head, a generally horizontally extending pivoting frame which extends transversely of said blow head, stationary cope and movable drag box halves mounted on said frame, and means on said frame to move said drag toward and away from said cope and to pivot said drag to extend downwardly or horizontally in the opposite direction.
