Problems solved by technology

[0003] The above-mentioned composite rubber material cannot be processed by using the existing rubber material molding device. If the inner rubber material and the outer layer rubber material are put into the existing rubber material molding device for processing, it is easy to mix the two rubber materials together. , the composite material after molding has no layered structure, and its performance is greatly reduced, unable to meet the specified requirements

Abstract

The invention discloses a forming device of a fuel pipe material. The forming device comprises a machine body, wherein an external flow passage body is arranged in the machine body, and an internal flow passage body is arranged in the external flow passage body; an external glue feed opening and an internal glue feed opening are formed in the machine body; the external flow passage body is provided with an external flow passage communicating with the external glue feed opening, and the internal flow passage body is provided with an internal flow passage communicating with the internal glue feed opening; an extrusion machine head is arranged at the front end of the machine body, and an external glue extrusion hole communicating with the external flow passage and an internal glue extrusion hole communicating with the internal flow passage are formed in the extrusion machine head; and an adhesion port connected with the internal glue extrusion hole and the external glue extrusion hole is formed in the front end of the extrusion machine head. The external flow passage body and the internal flow passage body in the forming device extrude materials in a layered manner, so that multilayer co-extrusion of mixed materials is completed, and a formed compounded rubber material has an obvious layered structure; an adhesion degree between the layers is high, the performance is good, and the forming device conforms to standard requirements of markets.

Description

technical field [0001] The invention relates to the field of molding fuel pipe materials, in particular to a molding device for fuel pipe materials. Background technique [0002] With the development of the automobile industry and the improvement of environmental protection requirements, the performance of fuel pipes in automobiles is also more stringent. In the past, fuel pipes made of a single material did not meet market requirements. Now we are processing a composite material for fuel pipes. The composite material has an obvious layered structure. The inner layer of the composite material is generally fluororubber (FKM), which has the properties of fuel oil thermal aging resistance and fuel penetration resistance; the outer layer The rubber compound is generally epichlorohydrin rubber (ECO / CO), or acrylate rubber (ACM), or ethylene acrylate rubber (AEM), which has properties such as weather resistance, ozone resistance, and fuel corrosion resistance. [0003] The above-...
