Claims

[Scope of utility model registration request]

In a two-split rubber molding mold consisting of an upper mold and a lower mold, and provided with a groove molding rib that intersects and joins the mating surfaces of the upper mold and the lower mold, the upper mold and the lower mold are Cut out an annular portion on at least one of the mating surfaces, with the inner edge being a line that envelopes the inner periphery of the mold at a predetermined depth from the mating surface, and a predetermined width apart from the inner edge on the outer periphery side. A mold for rubber molding, characterized in that a step surface continuous in the circumferential direction is provided, and the joint end surface of the groove-molded bone is made to protrude from the step surface to be flush with the mating surface.
