APPARATUS FOR KNOCKING OUT CASTING MOLDS Russian patent published in 2002 - IPC

FIELD: foundry. SUBSTANCE: apparatus for knocking out casting molds includes mechanism for lifting flasks with molds over casting conveyer; mechanism for feeding flasks to knocking out zone; device for pressing out lump of molding sand together with casting mold and knocking out grate. Mechanism for lifting flasks is arranged in gap of rail track of casting conveyer and it is in the form of two lifting cylinders with common rod. Body of one cylinder supports other cylinder whose body is joined with lifting table carrying rails. Flasks are fed onto lifting table for lifting them to necessary level. Mobile roller catches move flasks to knocking out zone. When lump of molding sand is pressed out onto knocking out grate, emptied flasks are fed to lifting table. Lifting cylinders are energized for moving downwards and flasks are moved to gap of rail track of conveyer. EFFECT: enhanced operational condition of apparatus due to reduced cross inertia forces, enhanced operational reliability, decreased investments. 1 dwg
