[0002] The forming mold is a mold made according to the shape and structure of the workpiece, and then the material can be cast, injected, etc. to form a certain shape. In the continuous processing of composite materials, the use of forming molds not only facilitates the integrated molding of composite materials, but also has high production efficiency and stable product performance.

[0003] In the manufacture of composite products, it is inevitable to use molding molds. Products and molds are usually one-to-one. Therefore, for the diverse needs of products, the corresponding number of molds are usually processed. For tube products, customers' requirements for length are almost unanimous. The usual practice is to process a set of molds to meet the production needs of products with more commonly used lengths.

[0004] However, for products with longer lengths, the mold needs to be reprocessed for production. At the same time, for the production of overly long parts, the required heating equipment (such as ovens, autoclaves, and hot presses) is larger, and the equipment cost and production cost rise sharply.

[0005] Therefore, we propose a self-heating molding mold for composite materials with adjustable length. When processing tubular products of different lengths, the length of the overall mold can be adjusted according to demand to meet the needs of different lengths. A heating module is added inside the mold to realize the self-heating function, avoid the requirements for heating equipment specifications, and reduce production costs. Utility Model Content
