Abstract
The invention relates to a vulcanizing method of a multifunctional hub oil seal, which adopts a vulcanizing mold comprising a mold cavity structure and a self-injection structure. The self-injection structure comprises that an annular groove matched with an oil seal cavity is arranged on the upper face of a middle mold body, an injection hole is arranged between the annular groove and the oil seal cavity, an upper mold body is arranged above the middle mold body, and a convex ring matched with the annular groove is arranged on the lower face of the upper mold body. The vulcanizing steps include mold combining, material feeding, warming and melting, material injecting, vulcanizing, demolding and the like. Due to the arranged self-injection structure, the vulcanizing mold omits a pre-molding processing procedure of sizing materials, is convenient and fast in material feeding, and improves integral production efficiency compared with other pre-molded oil seal vulcanizing molds. During vulcanizing, the sizing materials can be evenly filled in the whole cavity, the connection position of an injection port and products is automatically separated during mold opening due to the fact that the products are clamped on the lower portion of the mold, and the appearance of the products reaches higher quality effect.
