Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber molds, in particular to a carbon fiber mold device for modular and reconfigurable bicycle accessories. Background Art

[0002] The carbon fiber mold device for modular reconfigurable bicycle accessories is mainly composed of a mold body, an adjustable module and a connecting mechanism. The mold body is mainly made of high-strength carbon fiber material, which is both lightweight and highly durable. The surface is precisely processed to ensure adaptability and wear resistance. The adjustable module can be flexibly adjusted in multiple angles and sizes through a nested design and movable slide rails to adapt to different shapes of bicycle accessories. The connecting mechanism adopts a high-precision mechanical lock or magnetic structure to ensure the rapid disassembly and stable connection of the module. Its working principle is to form a closed cavity through splicing and angle adjustment between modules, and complete the molding of carbon fiber materials under high temperature and high pressure conditions, thereby producing bicycle accessories with precise shape and reliable strength.

[0003] Although the connection parts between modules are flexible, frequent disassembly and assembly operations may weaken their mechanical strength, especially in magnetic structures. Magnetic attenuation leads to insufficient locking force, and carbon fiber molds will expand and contract during high-temperature use, which may reduce the repeated service life. This will affect the stability of the connection between modules, and may cause slight misalignment in high-pressure environments, affecting the accuracy of the finished product. Summary of the invention

[0017] The present invention provides a modular and reconfigurable carbon fiber mold device for bicycle accessories, which has the following beneficial effects:

[0018] The carbon fiber mold device of this modular reconfigurable bicycle accessory effectively solves the problem of possible slight misalignment of the connection between modules under high pressure in the prior art through the innovative design of modular structure. Specifically, the combination of the first fixed ring and the first threaded ring ensures the initial stability of the mold structure; at the same time, the setting of the limit ring and the threaded teeth forms a multiple limit system, which further improves the reliability of the connection. In particular, the sliding connection design of the magnetic suction rod and the limit groove effectively overcomes the problem of magnetic attenuation by using high-performance NdFeB magnetic materials and three layers of nickel-copper plating, ensuring the connection strength and accuracy of the module during long-term use.

In addition, the key components are made of nickel-based alloy materials, which have extremely high oxidation resistance and high temperature resistance, ensuring reliability under high-pressure operating environments. Combined with the modular design concept, this technical solution significantly improves the flexibility of the mold device, so that it can adapt to the production needs of various varieties and specifications of bicycle accessories.
