Apparatus for removing rubber rings from a mold
Abstract
Abstract AN ARRANGEMENT FOR REMOVING RUBBER RINGS FROM SEMICIRCULAR GROOVES MACHINED IN THE OUTSIDE SURFACE OF A MOLD CORE. AFTER THE RINGS ARE MOLDED IN THE GROOVES AND THE MOLD OPENED, A RING REMOVAL MECHANISM IS ADVANCED TOWARDS THE CORE FOR DISLODGING AND REMOVING EACH RING FROM THE POSITION IN WHICH IT WAS MOLDED IN A CORE GROOVE. THE MECHANISM INCLUDES A BASE SUPPORTING A MOTOR WHICH DRIVES A PAIR OF ENDLESS RUBBER BELTS RESPECTIVELY MOUNTED ON ARMS LOCATED OF OPPOSITE SIDES OF THE CORE. AS THE MECHANISM IS MOVED INWARDLY INTO A RING ENGAGING POSITION, THE MOTOR DRIVEN BELTS CONTACT EACH RING SEQUENTIALLY AND BECAUSE OF THE FRICTION ESTABLISHED BETWEEN THE LINEARLY MOVING BELT AND EACH RING THE RING IS CAUSEDTO BE ROLLED OUT OF ITS GROOVE AND ONTO A STATIONARY BAR FOR SUBSEQUENT REMOVAL FROM THE MOLD APPARATUS.
