摘要： A SHOE BOTTOMING MACHINE HAVING A DIVIDED MOLD RING WITH INTERFACE GROOVES BETWEEN ITS HALVES TO FORM AN INJECTING SPRUE, SO ARRANGED THAT A BLOCK ON A PLASTICIZING PUMP FOR FORCING ELASTOMER INTO THE MOLD RING IS RELEASABLY ENGAGED TO FORM A COUPLING WITH KEYS ON THE MOLD RING HALVES WHENEVER THEY ARE BROUGH TOGETHER TO FORM A MOLDING CAVITY. THE KEYS ARE SUPPORTED ON PARTS OF A TWO-PART CARRIER AND THE BLOCK IS CONNECTED THROUGH A DISTRIBUTING MANIFOLD BETWEEN THE PUMP AND THE BLOCK IN A MANNER TO ENABLE RELEASE OF A SPRUE PLUG WHILE ATTACHED TO A MOLDED SHOE BOTTOM FROM THE MOLD RING WHEN THE MOLD RING PARTS ARE SEPARATED.
