Abstract

Core making machine, where the core box halves are mounted on plates driven towards each other in a frame. Mandrels project into the core box and are used to locate the cores, and ejectors push the hardened cores onto a conveyor. The mandrels are suspended vertically and, after the core box has been opened, part of the conveyor is moved under the box before ejection of the cores. The guide bars of the machine are pref. fitted with a holder from which the mandrels are suspended, and the ejector rods are driven through axial holes in the mandrels. A work cylinder is pref. used for the periodic movement of the conveyor. Fully automatic core making, core-ejection and removal of the cores on the conveyor, where the mandrels are used for accurate location of the cores in the core box.
