Abstract
A foundry molding machine is disclosed wherein a core or mold is molded from moldable material such as sand in first and second mold boxes having a cavity. The cavity is filled with the sand and is then cured to form the mold. The first and second mold boxes are separated so that the mold remains in the first mold box with a downwardly facing cavity. Any of several means may be used to assure that the mold remains in this downwardly facing cavity. A transfer conveyor is then moved to a position closely beneath the mold. The first mold box is then moved upwardly as ejection means acts on the mold to eject it downwardly onto the closely spaced transfer conveyor. The transfer conveyor then moves out from underneath the first mold box to remove the completed mold and the cycle repeats. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
