Compression vulcanization molding mold for rolling bearing seal, and method for manufacturing rolling bearing seal
The rolling bearing seal includes a core metal and rubber adhered to the core metal by vulcanization. The rubber includes: a seal lip portion having, over the entire circumference in the circumferential direction, a plurality of projections that extend inward in the radial direction from the inner diameter side of the core metal, and slides on a seal sliding surface of an inner ring of a rolling bearing; and an attachment portion that is attached to an outer ring of the rolling bearing. A compression vulcanization molding mold includes a female mold and a male mold. The female mold has a guide portion for positioning the core metal and a rugged shape forming the projections on the seal lip portion. The male mold has an inner-diameter-side burr groove and an outer-diameter-side burr groove and the shape of a radially outermost portion of the inner-diameter-side burr groove is formed in a circle.
