This invention discloses a flanged composite material air intake duct molding fixture, relating to the field of air intake duct molding fixture technology. It includes a core module, which forms the inner molding surface of the air intake duct component. The core module has a relatively upper first end face and a relatively lower second end face along its length, and includes several outer core molds. By redesigning the air intake duct molding fixture, a hard, non-soluble structure can be used as the core mold for the air intake duct component. Furthermore, after molding, it can be removed from the complex molding surface within the air intake duct component. This process avoids chemical pollution and the waiting period for the core mold to dissolve. Therefore, compared to traditional air intake duct component molding methods, the demolding speed is faster after molding, reducing environmental costs and avoiding potential chemical pollution problems. Moreover, during the molding of the composite material, the core mold will not react with the composite material at high temperatures.
