[0002] The carbon fiber product refers to a material product which is made of carbon fiber prepreg as raw material and processed by different processing methods to meet the use requirements. Since the carbon fiber has extremely high material properties, the strength and hardness of the carbon fiber product are much higher than those of the metal material of the same volume and weight. Therefore, the carbon fiber product has a wide application in the high-tech industrial fields such as aviation, navigation and military industry. The molding method is a processing method commonly used for most carbon fiber products. Therefore, a molding device is often used to perform molding processing on the carbon fiber product.

[0003] When the related molding device is used, the carbon fiber prepreg raw material is usually filled into the lower mold coated with a release agent, and then the upper mold is driven downward by a hydraulic device.
