[0001] The utility model patent relates to the technical field of carbon fiber thermoplastic winding molds, and specifically, to a detachable and resolvable mold device. Background Art

[0002] Thermoplastic resins have the properties of softening when heated and hardening when cooled, and they do not react chemically. They can maintain this property no matter how many times they are heated and cooled. All thermoplastic resins have linear molecular structures. They include all polymerized resins and some condensed resins. Thermoplastic resins have good toughness, large damage tolerance, good dielectric constant, unlimited storage period, no need for low-temperature storage, and no need for large-scale special equipment such as autoclaves for molding. In particular, they have good recyclability, recyclability, reusability, and do not pollute the environment. They adapt to the development direction of environmental protection of materials today.

[0003] When winding thermoplastic resin-based composite materials, a whole cylindrical thin-wall winding mold is usually used, and its wall thickness is 2mm. However, in actual winding production, after thermoplastic winding with increased tension, the composite fiber will shrink radially and tightly clamp on the mold surface. Since the wall thickness of 2mm is relatively thin, if the mold is forced to be demolded, it is easy to cause damage to the winding layer, and demolding is also very difficult. Therefore, the present application provides a detachable and distinguishable mold device. Utility Model Content
