Technical Field

[0001] The utility model relates to the technical field of rubber product molding and processing, in particular to a rubber ring flash removing device. Background Art

[0002] Rubber rings, especially rubber O-rings, need to be molded and vulcanized in a mold at a certain pressure during production. In order to prevent lack of rubber, the rubber filled in the mold cavity should maintain a certain amount of interference. The excess rubber overflows the mold cavity and forms flash. Rubber O-rings must be trimmed to obtain a product with a good appearance.

[0003] At present, the commonly used methods for removing flash of O-shaped rubber rings are manual trimming, frozen trimming, and water grinding trimming. When the existing rubber ring flash removal device removes the flash of the rubber ring, the flash outer cutting knife and the flash inner cutting knife move quickly under the force and are used for cutting, but the stability of the flash outer cutting knife and the flash inner cutting knife in applying the force cannot be guaranteed during this process, so that the quality of the edge removal is difficult to ensure.
