Description

Technical Field

[0001] This utility model belongs to the field of composite material grid forming mold technology, specifically relating to a composite material grid forming mold. Background Technology

[0002] Composite materials have high specific strength, specific modulus and corrosion resistance, and have many applications in the aerospace industry, rail transportation, sports and leisure, including carbon fiber resin composite materials.

[0003] Carbon fiber resin composite gratings possess advantages such as large moment of inertia, excellent bending and buckling resistance, and high structural efficiency, making them widely used in numerous fields including aircraft fuselages and high-speed rail. Existing carbon fiber resin composite gratings typically employ manual prepreg application. This process involves initially curing carbon fibers and resin to form a prepreg, cutting it to lengths matching the forming grooves in a mold, and then continuously laying the prepreg into the mold grooves. After laying, the prepreg is cured to form the grating. This manufacturing method is inefficient, costly, and cannot be used for continuous application. Utility Model Content

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0024] like Figures 1 to 4 As shown, a composite material grid molding die in one embodiment of the present invention includes a die body 11, which is a cuboid or a cube. The die body 11 includes a forming surface, a fixing surface and a guiding surface. The forming surface is the upper end surface of the die body 11, the fixing surface is the lower end surface of the die body 11, and the guiding surface is the four side end surfaces of the die body 11.

[0025] Multiple protruding molding blocks 21 are fixedly connected to the molding surface. The molding blocks 21 are bonded or welded to the molding surface. A molding groove matching the grid is formed between the molding surface and the multiple molding blocks 21. The height of the molding groove is 19 to 21 mm, specifically 20 mm, and the width of the molding groove is 14 to 16 mm, specifically 15 mm.

[0026] The shape of the molding block 21 and the spacing between adjacent molding blocks 21 are different, that is, the molding grooves formed by the molding block 21 and the molding surface are different. Different molding grooves result in different grids formed after the prepreg laid in the molding grooves cures. Therefore, the shape of the molding block 21 and the spacing between adjacent molding blocks 21 can be changed according to the shape and size of the grid.

[0027] The forming groove includes multiple first forming grooves 22 in the same direction and multiple second forming grooves 23 in the same direction. The multiple first forming grooves 22 are connected and the multiple second forming grooves 23 are connected.

[0028] Specifically, multiple first forming grooves 22 can be connected, and multiple second forming grooves 23 can be connected to form a complete, uninterrupted, curved laying path. Continuous laying can be performed along this path. The prepreg body 51 can be laid sequentially and continuously in the first forming grooves 22. After laying one first forming groove 22, it is easy to turn and lay in another first forming groove 22, until the prepreg body 51 is laid in all the first forming grooves 22. Then, the prepreg body 51 is laid sequentially and continuously in the second forming grooves 23, until the prepreg body 51 is laid in all the second forming grooves 23, ensuring that the laid prepreg body 51 matches the size of the grid. No cutting of the prepreg body 51 is required, achieving continuous laying and increasing the efficiency of grid forming.

[0029] Specifically, it can be laid manually or by a robotic arm, which enables automated laying. Multiple fixing holes 41 are provided on the fixed surface, with a number of 6 to 10 holes. These fixing holes 41 facilitate the connection of the mold body 11 to other structures and the movement of the mold body 11. Combined with the robotic arm, automated laying and forming can be achieved.

[0030] The molding block 21 is provided with an inclination angle of 1 to 2 degrees, and the number of inclination angles is 1 to 2. The inclination angles are rounded corners set on the edges of the molding block 21. In this way, there is a gap between the molded grid and the molding block 21, which facilitates demolding after the grid is formed.

[0031] Multiple guide posts 32 are fixedly connected to the guide surface. Threaded holes are opened on the guide surface. Threaded sections matching the threaded holes are opened on the guide posts 31. Fixing parts 32 are provided on the guide posts 31.

[0032] When laying the prepreg body 51, as the prepreg body 51 moves from one first molding groove 22 or second molding groove 23 to another, the prepreg body 51 can be secured to the guide post 31. That is, the guide post 31 can abut against the prepreg body 51 and provide support for the prepreg body 51. This facilitates the changing direction of the winding process during molding and applies winding tension to the prepreg body 51, ensuring the flatness of the prepreg body 51 and preventing wrinkles from forming. Otherwise, gaps may occur between the upper and lower prepreg bodies 51, resulting in an unstable grid after molding.

[0033] In this way, when the prepreg body 51 turns, the prepreg body 51 laid in the previous first molding groove 22 or second molding groove 23 will not detach. The guide post 31 is provided with a fixing part 32. Specifically, when laying the prepreg body 51, one end of the prepreg body 51 can be fixed to the guide post 31. The fixing part 32 can easily pass through the prepreg body 51, so that the prepreg body 51 is fixed to the guide post 31, and one end of the prepreg body 51 is fixed, which facilitates the laying.

[0034] The guide post 31 is easy to install and remove. The number of guide posts 31 can be increased or decreased according to the number of the first forming groove 22 and the second forming groove 23, so that there are enough guide posts 31 to support the prepreg body 51.

[0035] When using, refer to Figures 1-4As shown, when laying the prepreg body 51, the prepreg body 51 can be continuously laid in the first molding groove 22 or the second molding groove 23. When turning from one first molding groove 22 or the second molding groove 23 to another first molding groove 22 or the second molding groove 23, the guide post 31 can increase the stability during the turning, making it difficult for the laid prepreg body 51 to detach from the first molding groove 22 or the second molding groove 23.

[0036] Compared with the prior art, the composite material grid forming mold of this utility model has a simple structure, high efficiency, and can be continuously laid.
