Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0029] This embodiment provides a carbon fiber molding and fixing device, see Figure 1-Figure 5 As shown, it includes an upper cover plate 1 and a lower cover plate 2, wherein a first cavity 11 is formed in the upper cover plate 1, and a second cavity 21 is formed in the lower cover plate 2. A vacuum valve 22 is provided on the side of the lower cover plate 2, and the vacuum valve 22 is connected to the second cavity 21. A sealing strip is provided on the mating surface of the upper cover plate 1 and the lower cover plate 2.

[0030] In the above embodiment, the carbon fiber forming fixture is composed of an upper cover plate 1 and a lower cover plate 2. A second cavity 21 is formed in the lower cover plate 2. Carbon fiber material, such as carbon fiber cloth, is laid in the second cavity 21. The second cavity 21 provides preliminary support for the carbon fiber cloth. The carbon fiber cloth is placed in the second cavity 21 after being impregnated with resin. The carbon fiber cloth can also be coated with resin for a second time in the second cavity 21 so that the carbon fiber is fully impregnated with the resin. A first cavity 11 is formed in the upper cover plate 1. The upper cover plate 1 is covered on the upper part of the lower cover plate 2 so that the first cavity 11 and The second cavity 21 is fitted to form a mold cavity. On the one hand, the mold cavity squeezes the impregnated carbon fiber material so that the resin can fully fill the gap inside the carbon fiber material, promote the fusion of the resin and the carbon fiber material, and increase the density of the carbon fiber material, which is beneficial to improve the firmness and stability of the carbon fiber material after molding. On the other hand, the carbon fiber material is placed in the mold cavity and then put into the autoclave for baking. The cover plate can support the carbon fiber material to prevent the carbon fiber material from bending and deforming under its own gravity during the baking process, which is beneficial to improve the molding quality of the carbon fiber material. In addition, bubbles will be generated during the process of impregnating the carbon fiber material with resin. The bubbles will weaken the adhesion between the resin and the carbon fiber, resulting in a decrease in the interface bonding strength, thereby affecting the tensile and compressive mechanical properties of the material. Therefore, a vacuum valve 22 is provided on the side of the lower cover plate 2, and the vacuum valve 22 is connected to the second cavity 21. When the first cavity 11 and the second cavity 21 are fitted to form a mold cavity, the vacuum valve 22 is connected to the vacuum pump to extract the gas in the mold cavity to cause the bubbles to escape from the resin, thereby reducing or eliminating the bubbles, which is easy to improve the quality and stability of the carbon fiber product after molding. Furthermore, a sealing strip is provided on the mating surface of the upper cover plate 1 and the lower cover plate 2, which is beneficial to improving the sealing of the mold cavity and further improving the efficiency of removing bubbles.

[0031] In one embodiment of the present application, see Figure 2 As shown, a module plate 23 is disposed in the second cavity 21 of the lower cover plate 2 .

[0032] In the above embodiment, during the molding process of the carbon fiber material, it is necessary to mold the carbon fiber material into different external shapes according to actual needs. A module plate 23 is provided in the second cavity 21 of the lower cover plate 2. The placement position of the module plate 23 can be changed as needed. Preferably, the model plate 23 can also be replaced with modules of different shapes. A plurality of model plates 23 can be provided, and then the shape of the inside of the mold cavity is adjusted according to the molding requirements of the carbon fiber material, so as to adapt to different product external shape requirements, for example Figure 1 As shown, when the carbon fiber board 100 is formed, grooves need to be reserved on the side to accommodate the later processing and assembly of the carbon fiber board 100. A module board 23 can be placed in the second cavity 21 to adjust the internal shape of the mold cavity, thereby changing the external shape of the carbon fiber board 100 after molding in the mold cavity.

[0033] In one embodiment of the present application, refer to Figure 1 As shown, handles 3 are installed on the sides of the upper cover plate 1 and the lower cover plate 2.

[0034] In the above embodiment, handles 3 are installed on the sides of the upper cover plate 1 and the lower cover plate 2 to increase the gripping points and facilitate the opening and closing of the upper cover plate 1 and the lower cover plate 2.

[0035] In one embodiment of the present application, see Figure 1 As shown, the handle 3 is arranged in a ring shape.

[0036] In the above embodiment, the ring-shaped handle 3 is easier to grasp. In addition, the ring-shaped handle 3 is suitable for matching with the lifting hook, so that the lifting tool can lift and transport the cover plate.

[0037] In one embodiment of the present application, see Figure 1 As shown, a positioning hole 12 is opened on the upper cover plate 1 , and a positioning column 24 is provided on the lower cover plate 2 .

[0038] In the above embodiment, when the upper cover plate 1 is hoisted and fitted with the lower cover plate 2 in the vertical direction, the positioning hole 12 is used to be socketed and positioned with the positioning column 24 to prevent the upper cover plate 1 and the lower cover plate 2 from deviating during the fitting and docking, which is beneficial to improve the alignment of the upper cover plate 1 and the lower cover plate 2 when they are fitted together and improve the fitting efficiency.

[0039] In one embodiment of the present application, see Figure 3 As shown, a pry hole 13 is provided on the side of the upper cover plate 1 .

[0040] In the above embodiment, when the upper cover plate 1 and the lower cover plate 2 are fitted together, they may be too tight to be separated. The pry hole 13 set on the side of the upper cover plate 1 provides a fulcrum for a crowbar. When the upper cover plate 1 and the lower cover plate 2 are tightly fitted and difficult to separate, the crowbar is inserted into the pry hole 13, and the upper cover plate 1 is pried off the lower cover plate 2 by using the lever principle, which is beneficial to improving the mold removal efficiency.

[0041] In one embodiment of the present application, see Figure 4 As shown, the sides of the upper cover plate 1 and the lower cover plate 2 are connected via a rotating shaft 14 .

[0042] In a preferred embodiment of the present application, the sides of the upper cover 1 and the lower cover 2 are connected by a rotating shaft 14, and the upper cover 1 can be rotated around the rotating shaft 14 to be opened relative to the lower cover 2. Compared with fitting the upper cover 1 and the lower cover 2 in the vertical direction, the upper cover 1 can be directly rotated around the rotating shaft 14 to fit the lower cover 2 without lifting, which is beneficial to improving the convenience and efficiency of opening and closing the upper cover 1 and the lower cover 2.

[0043] In one embodiment of the present application, see Figure 5 As shown, a roller 25 is installed at the bottom of the lower cover plate 2.

[0044] In the above embodiment, the roller 25 is installed at the bottom of the lower cover plate 2 to reduce the friction between the lower cover plate 2 and the ground, which can make the transfer of the carbon fiber molding fixture more convenient.

[0045] In the actual use of the present application: carbon fiber materials, such as carbon fiber cloth, are stacked and laid in the second cavity 21, and each layer of carbon fiber cloth is coated with resin in the second cavity 21 so that the carbon fiber is fully impregnated with the resin. A first cavity 11 is formed in the upper cover plate 1, and the upper cover plate 1 is covered on the upper part of the upper cover plate 1 so that the first cavity 11 and the second cavity 21 are fitted together to form a mold cavity. The carbon fiber material is extruded and plasticized in the mold cavity. A vacuum valve 22 is provided on the side of the lower cover plate 2, and the vacuum valve 22 is connected to the second cavity 21. When the first cavity 11 and the second cavity 21 are fitted together to form a mold cavity, the vacuum valve 22 is connected to a vacuum pump to extract the gas in the mold cavity, which can cause bubbles to escape from the resin. Figure 1 As shown, a carbon fiber plate 100 is formed in a mold cavity.
