Description

Technical Field

[0001] The utility model belongs to the technical field of water seal structure moulds, in particular to a straight strip mould with a C-shaped water seal structure. Background Art

[0002] Under traditional process conditions, the original C-type water seal straight section adopts a flat plate with an expanded width and a T-shaped head, and the cloth layer is pre-vulcanized during the production process; after the flat plate is produced, if there is a secondary heating equipment such as a steamer, a secondary steam shaping vulcanization is carried out; if there is no secondary heating equipment, most of the initial shaping is carried out by the permanent deformation method. Specifically, after the flat plates are stacked, the rubber is deformed by its own weight or the weight of auxiliary external objects, and it is left to stand for a long time to make the rubber produce a certain permanent deformation, thereby achieving a preliminary shaping effect.

[0003] However, the C-shaped water seal straight section prepared by the above mold and process is not vulcanized into a C-shape at one time. It is bent into shape by external force during actual installation and use, which easily causes the internal stress of the product to be concentrated in the arc part; and when the arc part is formed by external force, the outer colloid is stretched and the inner colloid is compressed. The rubber body is in this stress state for a long time, which will accelerate aging and reduce the service life due to internal stress; in addition, in the shaping process, only the surface is physically shaped, rather than the integrated vulcanization shaping of the rubber molecular chain microstructure hinge. The vulcanized plate will be subjected to secondary high temperature, and the rubber body is prone to accelerated aging due to over-sulfurization, thereby reducing the service life of the water seal.
