The invention discloses an outer water cutting sealing strip with a hollow structure. The sealing strip comprises an automobile door outer plate, an automobile door inner plate and automobile door glass. An upper end of the automobile door outer plate wraps the automobile door inner plate, the outer water cutting sealing strip is included, the automobile door glass makes contact with the outer water cutting sealing strip, the outer water cutting sealing strip is composed of a metal framework and a wrapping flexible glue, and the metal framework is wrapped by the wrapping flexible glue and thenis extruded and formed; the metal framework adopts a double-rib steel belt; a cavity is formed in the wrapping flexible glue so that the secondary stretch bending forming procedure of the outer watercutting sealing strip which is co-extruded by adopting a flat steel belt is avoided, the production cost is reduced, and a product percent of pass is ensured; the outer water cutting sealing strip adopting the double-rib steel belt for co-extrusion has certain three-dimensional bendability so that a secondary stretch bending forming process is avoided, and the production cost is reduced; and theproblem of surface sink marks of a double-rib steel belt co-extrusion product is solved.
本发明公开了一种带中空结构的外水切密封条,包括车门外板、车门内板和车门玻璃,且车门外板上端包裹住车门内板,还包括外水切密封条,且车门玻璃与外水切密封条接触,所述外水切密封条由金属骨架和包覆软胶组成,所述金属骨架被包覆软胶包裹后一并挤出成型;所述金属骨架采用双筋钢带;所述包覆软胶内设有空腔,避免了采用平板钢带进行共挤出的外水切密封条二次拉弯成型工序,降低了生产成本,且保证了产品合格率;采用双筋钢带进行共挤出的外水切密封条,具有一定的三维弯曲性,避免了二次拉弯成型工序,降低了生产成本;解决了双筋钢带进行共挤出产品表面缩痕的问题。
