Forming method for hollow rubber sealing element with fabric

The invention relates to the technical field of sealing, and particularly discloses a forming method for a hollow rubber sealing element with fabric. The forming method for the hollow rubber sealing element with the fabric can be used for forming the hollow rubber sealing element with the fabric, and the wall thickness of a cavity of the prepared hollow rubber sealing element product with the fabric is uniform; By adopting extrusion forming, a vulcanized semi-finished product is obtained, the production efficiency of the semi-finished product is improved, engineering production is realized, the surface of the fabric is attached to the semi-finished product, the use requirements are met, and the influence that due to the fact that in the forming process, the rubber is pressed to flow, a mold core is deformed, and the wall thickness of a cavity of the product is uneven is reduced; and the problem that in an existing forming method for a hollow rubber sealing element with fabric, in the high-temperature pressing
