Industrial tire mold

Abstract

Abstract A MOLD FOR INDUSTRIAL TIRES AND WHEELS OF POLYURETHANE AND THE LIKE HAS A LOWER PORTION, AN OPEN-TOP UPPER PORTION, A COVER FOR THE UPPER PORTION, AND PROVISION FOR SPACERS BETWEEN THE LOWER AND UPPER MOLD PORTIONS FOR ADJUSTING THE HEIGHT OF THE MOLD TO ACCOMMODATE TIRES OR WHEELS OF DIFFERENT AXIAL DIMENSIONS. THE MOLD RECEIVES AN ANNULAR HUB TO THE SURFACES OF WHICH A POLYURETHANE OR LIKE SOLID TIRE IS TO BE MOLDED. THE LOWER MOLD HAS A SPINDLE HAVING HOLLOW RADIAL ARMS WITH PINS THEREIN WHICH MAY BE CAMMED RADIALLY OUTWARDLY. A SLEEVE EXTENDS UPWARDLY FROM THE SPINDLE THROUGH THE LID OF THE UPPER MOLD PORTION. A STEM WITHIN SAID SLEEVE HAS A CAM AT ITS LOWER END AND A NUT AT ITS UPPER END. TURNING THE NUT CAUSES THE STEM TO MOVE DOWNWARDLY AND CAMS THE RADIAL PINS OUTWARDLY TO PRESS AGAINST THE INNER SURFACE OF THE ANNULAR HUB THEREBY TO MAINTAIN THE HUB CENTERED ABOUT THE AXIS OF THE MOLD. THE MOLD COVER HAS A HUB PORTION HAVING THEREIN CAM FOLLOWERS WHICH ENGAGE CAM SLOTS IN THE OUTER SURFACE OF THE SLEEVE SO THAT BY MOVING THE LID ROTATIONALLY THE LID IS CAMMED DOWNWARDLY INTO CLOSED POSITION.
