Problems solved by technology
In this process, the seal needs to vulcanize multiple product sections, which are then spliced and formed, and the appearance quality of the product joints is poor
Seals with composite wear-resistant fabric on the surface can also be preformed with rubber and fabric, and then inflated. However, in this process, because the silicone rubber is soft, it cannot be preformed for inflated molding.

Abstract
The invention relates to a hollow sealing part with fabrics on the surface and a forming mold and method thereof. A sealing part of a segmented pressing splicing forming process needs to be spliced and formed after a plurality of product sections are vulcanized, and the appearance quality of a joint part is poor. The method for preparing the hollow sealing part with fabrics on the surface comprises the following steps: preparing a semi-finished product; wrapping surface fabrics on the surface of the semi-finished product through tackifying glue; placing the semi-finished product wrapped by the surface fabrics in a forming mold; and inflating the semi-finished product wrapped by the surface fabrics through an inflation channel reserved in the forming mold to form the sealing part. According to the sealing part, the semi-finished product of a hollow closed structure for inflation molding is involved in the forming process and then is coated with the tackifying glue so that inflation molding of a low-viscosity silicone rubber product is realized, the surface of the obtained sealing part is wrapped by the fabric layer, the outer surface of the sealing part is free of joints, and the appearance is good; the surface fabrics of the sealing part is free of glue permeation, and the friction coefficient is low; and the overall size is good, and the installation matching degree is good.
Description
technical field [0001] The invention belongs to the technical field of seal forming, and in particular relates to a hollow surface belt fabric seal, a forming mold and a method thereof. Background technique [0002] Due to the reduction of air pressure at high altitude, there is a pressure difference between the cabin and the outside of the cabin. In order to ensure the comfort and flight safety of the aircraft, it is necessary to pressurize the cabin to ensure the normal activities of personnel, and install seals on the door frame of the aircraft. In order to realize the sealing of the cabin. The seal is usually a hollow structure, and the hollow structure will produce large deformation under small stress, effectively avoiding the shear damage caused by the excessive interference of the seal, and at the same time, the requirements for the machining accuracy of the mechanical installation part can be appropriately relaxed , to better fit the aircraft door frame. The appear...
