Description

Technical Field

[0001] The utility model belongs to the technical field of integrated hub cover forming equipment, and particularly relates to an integrated carbon fiber hub cover forming device. Background Art

[0002] The carbon fiber hub cap integrated molding device is a device specially used to produce carbon fiber hub caps. Carbon fiber hub caps are commonly used in high-performance cars, motorcycles, bicycles and other fields. The device is usually composed of a carbon fiber prepreg feeding system, a mold, a heating furnace, a pressure control system and a cooling device.

[0003] During the operation of the device, carbon fiber prepreg (composed of carbon fiber and resin) is provided by the feeding system and fed into the mold. Then, the heating furnace heats the mold to melt the resin. Subsequently, appropriate pressure is applied to evenly compact the carbon fiber and molten resin in the mold and make it completely consistent with the preset shape. Finally, the molded hub cap is quickly cooled by the cooling device to solidify it and obtain the required mechanical properties.

[0004] The use of the carbon fiber hub cover integrated molding device can realize the integrated molding of the hub cover without the need for traditional assembly processes. This can improve the strength, rigidity and wear resistance of the hub cover, reduce the weight of the entire vehicle, improve the performance of the suspension system, and enhance the vehicle's handling and fuel economy.

[0005] The mold design of the existing carbon fiber hub cover integrated molding device may be insufficient and cannot accommodate the buckle or cannot smoothly fix the buckle inside the hub cover, which may make the assembly process difficult or impossible. Therefore, we hope to design a carbon fiber hub cover integrated molding device with a new structure to solve this problem. Utility Model Content
