Description

Technical Field

[0001] The utility model relates to the technical field of rubber sealing ring processing, in particular to a rubber sealing ring trimming device. Background Art

[0002] Sealing rings are mostly ring-shaped objects made of rubber as raw material, generally used for sealing and fixing. Sealing rings first need to be pressed in a mold during production. When the molded product is vulcanized, the rubber quickly fills the mold cavity, and the excess part (in order to prevent lack of rubber, the rubber filled in the mold cavity should maintain a certain amount of interference) overflows, forming overflow glue, that is, flash. In order to make the product meet the specified size and ensure the appearance quality, the finished product after vulcanization needs to remove these excess rubber edges first, and needs to be trimmed.

[0003] When using the existing rubber sealing ring trimming device, the sealing rubber ring is usually fixed, and then the cutting knife is brought into contact with the rubber sealing ring. Then, the rubber sealing ring is rotated to make the cutting knife cut and remove the burrs of the rubber sealing ring. However, this trimming method can only trim a single box frame sealing ring at a time. In the case of batch production of rubber sealing rings, the single trimming method is relatively time-consuming and labor-intensive, which reduces the processing efficiency of the rubber sealing rings.
