[0001] The utility model patent relates to the technical field of composite materials. Specifically, it relates to a composite material special-shaped hollow tube integral forming mold. Background Art

[0002] With the continuous development of composite material technology, its excellent properties have gradually been recognized by people, and its application scope is also constantly expanding. It is mainly used in various industries such as aerospace, automotive, rail transit, shipbuilding, and construction. The integral forming technology of composite materials can significantly reduce the number of parts, reduce the production process, and improve production efficiency; at the same time, it can also better exert the overall mechanical properties and improve product quality. The integrated design and production of composite material products are inseparable from a forming mold with a reasonable structure. The utility model patent provides a composite material special-shaped hollow tube integral forming mold for the production and manufacturing of the inflatable bag molding process of the composite material direction special-shaped hollow tube, so as to improve production efficiency and overall performance.

[0003] A Chinese patent with the publication number CN220883035U discloses a forming mold, which includes an upper mold mechanism, a lower mold mechanism, a first forming component, and a second forming component. The first forming component is arranged on the lower mold mechanism, and the second forming component is arranged on the lower mold mechanism and is arranged opposite to the first forming component. When the upper mold mechanism and the lower mold mechanism are closed, they cooperate with the first forming component and the second forming component to enclose a forming cavity for injection molding products. The first forming component includes a first forming slider. When the upper mold mechanism is inserted into the first forming component, the first forming slider participates in enclosing to form a forming cavity. When the upper mold mechanism and the lower mold mechanism are opened, the first forming slider moves towards the lower mold mechanism to retreat from the formed product. When the above-mentioned forming mold is opened, the upper mold mechanism drives the first forming slider to move towards the lower mold mechanism, so that the first forming slider retreats from the formed product, reducing the demolding difficulty of the forming mold, and then enabling the forming mold to stably complete the demolding of products with undercuts, improving the forming stability.

[0004] However, the traditional design and manufacturing methods in the prior art will increase the number of parts produced and the production process, increase the weight of the product and the production and manufacturing cost. At the same time, the production efficiency is low, the material injection is uneven, and the finished product rate is low. Summary of the Utility Model

[0006] The present utility model is realized as follows. A composite material special-shaped hollow tube integrated molding die includes an upper die, a lower die, and a clamping frame. The upper die is clamped to the top of the lower die, and the clamping frame clamps both ends of the upper die and the lower die.

[0007] A molding groove is provided in the middle of the upper die, positioning holes are provided at both ends of the upper die, and a transverse groove is provided in the upper die.

[0008] The internal grooving structures of the lower die and the upper die are symmetrically arranged.

[0009] Positioning pins are installed in the positioning holes and are respectively clamped to the upper die and the lower die.
