Abstract

A molding die for a carbon fiber three-piece composite wheel rim, and the invention relates to the field of wheel rim molding dies. A carbon fiber three-piece combined rim. The inner end surface of the outer rim and the outer end surface of the inner rim are fixedly connected by high-strength glue to form a rim body. The inner end of the spoke is provided with a central boss, and the central boss of the spoke It is arranged in the central cavity of the rim body, and the spokes are locked and connected with the rim body. The forming mold includes an outer rim mold set and an inner rim mold set. When the upper mold and the lower mold of the outer rim mold set are closed, the top surface of the annular boss of the upper mold and the bottom surface of the annular inner groove of the lower mold A cavity that is consistent with the contour shape of the outer rim to be made is formed between them to form the outer rim contour; the inner core of the inner rim mold set, the mold cover and the inner core of the round cake are coaxially arranged and inserted into each other for positioning , the outer mold of the circular tube, the mold cover and the mold bottom are coaxially arranged and inserted into each other for positioning. The invention is used for forming carbon fiber rims.

Description

technical field

[0001] The invention relates to the field of wheel rim forming dies, in particular to a forming die for a carbon fiber three-piece composite wheel rim. Background technique

[0002] Carbon fiber reinforced polymer composite materials are a series of high-performance composite materials prepared with carbon fiber as reinforcement, resin as matrix, and special molding and processing methods for advanced composite materials. Because the composite material has high specific strength and specific modulus, fatigue resistance and corrosion resistance, it has been more and more used in automobile parts in recent years. Compared with traditional steel or aluminum rims, carbon fiber rims are stronger and lighter than aluminum rims, so that they can meet the requirements of high lightness and lightweight.

[0003] For carbon fiber rims, the design and manufacture of single-piece rims is difficult and difficult to form, while the forming of three-piece combined rims is ...
