Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of carbon fiber composite material car shell flexible curing mould for racing car, and particularly relates to a carbon fiber composite material car shell flexible curing mould for racing car. BACKGROUND

[0002] The existing racing car monocoque shell mould of the university formula car race is mainly in the mode of machining male mould and then manually turning female mould, which turns female mould by milling foam or wooden male mould and then turning female mould on the basis of male mould by mixing resin and glass fiber or carbon fiber, the turning mould process is very time-consuming, and needs to repeatedly brush resin, repeatedly wait for curing and repeatedly polish, the method has the advantages that carbon fiber needs to be heated during forming, and the mould of carbon fiber monocoque shell made of carbon fiber or glass fiber can guarantee the consistency of the expansion of the mould and the monocoque shell during thermal deformation, and the cost is also lower compared with directly milling metal mould, and the disadvantages are that the workload is large, the working environment is poor, the turning mould process is prone to cause hole position error, and repeated polishing makes it difficult to have a reference surface for the monocoque shell, which causes difficulty in subsequent processing.

[0003] In the patent with publication number CN111890601B, a steel monocoque shell mould forming process and forming mould of a racing car based on the university formula car race are provided, which includes a front plate, a reinforcing rib, a front upper plate, a right side plate, a right bottom plate, a rear upper plate, a formed monocoque shell, a left side plate, a left bottom plate, a mould parting ear piece group and a pin fixed positioning plate, and can be completed by steel plate sheet metal, which greatly reduces the cost, the components involved in the mould are processed by laser cutting, the hole positions generated by the pin fixed positioning plate are also opened by laser, the hole position precision is high, a steel plate with high flatness is used as the steel sheet metal mould forming material, the polishing process is avoided, the monocoque shell manufactured by the forming mould has a high-precision reference surface, which facilitates the positioning work of subsequent racing car manufacturing, each sheet metal part has a pin, a positioning hole and a concave-convex block, and can be positioned and fixed with each other during welding or mould closing, so the precision between each surface is high, laser cutting and sheet metal work can be completed by machines, only a small amount of manual operation is needed in welding work and mould closing work, the use of viscous liquids such as resin is avoided, and the generation of harmful gases or dust is also avoided, but the following problems still exist in the patent.
