Description
Technical Field
[0001] This invention relates to the field of electromagnetic induction heating molding molds for composite materials, and particularly to an electromagnetic induction mold for irregularly shaped flat components. Background Technology
[0002] Fiber-based polymer composites (such as carbon fiber reinforced composites and glass fiber reinforced composites) are widely used in aerospace, automotive, and construction fields due to their lightweight, high strength, and corrosion resistance. However, traditional molding processes face multiple technical bottlenecks in the manufacturing of complex irregular-shaped flat components, such as low heating efficiency, significant internal and external temperature gradients, uneven material curing, and high mold costs.
[0003] Electromagnetic induction heating technology, as a technique that utilizes alternating magnetic fields to generate eddy current heating effects in conductive or magnetic materials to achieve rapid local heating, can achieve gradient heating of complex components through flexible design of coil shape and magnetic field distribution. However, existing technologies still have the following shortcomings: (1) Insufficient collaborative design of mold materials and electromagnetic properties leads to limited heating efficiency; (2) Lack of multi-physics field coupling optimization makes it difficult to balance the electromagnetic-thermal-mechanical field distribution; (3) Low level of intelligent control makes it impossible to dynamically adjust process parameters. Therefore, designing and developing an electromagnetic induction mold for irregularly shaped flat components is of great significance for breaking through key technical bottlenecks such as precise forming of complex structures, collaborative control of multi-physics fields, and precise regulation of material properties.
