A foundry core making machine is disclosed which produces large or fragile cores. The core is initially made in two parts, which are later adhered together by movement between first and second stations. The separate core halves are made in third and fourth stations and then relatively moved to be in the first and second stations, vertically one above the other, and with flat surfaces facing each other. The core box booking means is utilized to move the lower core half upwardly against the upper core half to have the two adhere together. This same booking means was previously used to press vent grooves in one core half so that when the two core halves were assembled, a generally centrally extending core venting aperture was established. The core box ejection means then ejects the completed core from one core box in a carefully controlled movement. 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.

Simplified foundry core making machine and method

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.
