Description

Technical Field

[0001] The utility model relates to the technical field of composite material manufacturing, specifically to a four-sided pressurized carbon fiber molding tool with reasonable structure and simple operation, which can realize simultaneous pressurization of processing materials in a mold in multiple directions such as up, down, left and right, thereby improving the molding quality of the workpiece. Background Art

[0002] Carbon fiber molding tooling is a crucial tool used in the carbon fiber composite molding process. It provides precise molding shape and dimensions, ensuring that carbon fiber products achieve the exact appearance and specifications required by the design. Carbon fiber molding tooling typically requires high precision, uniform pressure transmission, good thermal conductivity, high lightness and rigidity, wear resistance, and a reasonable exhaust design to ensure a qualified product. Uniform pressure transmission is the most important requirement for carbon fiber molding tooling, ensuring that the pressure from the molding machine is evenly distributed within the mold, ensuring that the carbon fiber material is evenly stressed during the molding process.

[0003] Existing carbon fiber molding tooling primarily consists of an upper and lower mold plate that snap together to form a mold cavity. A mold body is further positioned within the upper and lower mold plates. During processing, the material to be molded is placed within the mold body, which is then placed within the mold cavity formed by the snapping of the upper and lower mold plates. The extrusion force of the upper and lower mold plates, combined with the mold cavity, pressurizes the carbon fiber composite material on the mold body. This molding method primarily focuses the molding pressure in the vertical direction, leaving little pressure around the mold body, resulting in suboptimal workpiece quality. Summary of the Invention

[0004] In response to the shortcomings and deficiencies in the existing technology, the utility model proposes a four-sided pressurized carbon fiber molding tooling with a reasonable structure, simple operation, and the ability to simultaneously pressurize the processing material in the mold in multiple directions, such as up, down, left and right, thereby improving the molding quality of the workpiece.

[0005] The utility model is achieved through the following measures:

[0006] A carbon fiber molding tool with pressure on all sides is provided with an upper mold module and a lower mold module. Corresponding upper mold body limiting grooves and lower mold body limiting grooves are respectively provided on the upper mold module and the lower mold module. After the upper mold module and the lower mold module are buckled together, the upper mold body limiting groove and the lower mold body limiting groove form a mold body cavity, and the mold body is placed in the mold body cavity. It is characterized in that a pressure block is also provided on the lower mold module, and the pressure block is located on the side of the lower mold body limiting groove. The side of the pressure block close to the mold body is provided with an arc corresponding to the shape of the mold body, and the side of the pressure block away from the mold body is inclined. The upper mold module is provided with a push block relative to the pressure block, and the side of the push block close to the mold body is provided with a pushing inclined surface for cooperating with the outer inclined surface of the pressure block. After the upper mold module and the lower mold module are buckled together, the push block presses down and pushes the pressure block close to the mold body.

[0007] The utility model describes that two pressure blocks are symmetrically provided on the lower mold module around the lower mold body limiting groove. Correspondingly, the upper mold module is provided with two push blocks respectively cooperating with the two pressure blocks. Furthermore, the pressure block is movably connected to the bottom plate of the lower mold module, and a pressure block limiting groove is provided on the bottom plate of the lower mold module, and the pressure block is placed in the pressure block limiting groove; further, the push block is movably connected to the upper mold module, and a push block limiting groove is provided on the top plate of the upper mold module, and corresponding screw holes are provided on the push block limiting groove and the push block, and the push block is fixed by screws.

[0008] In order to prevent the push block from tipping over during mold closing and pressurizing, the utility model further provides a push block limit plate on the upper mold module. The push block limit plate is arranged on the outside of the push block (i.e., the side away from the mold body) and is arranged parallel to the push block.

[0009] In order to ensure that the pressure block only moves toward the mold body during the mold closing and pressurizing process, the utility model further provides two pressure block limiting plates at both ends of the bottom plate of the lower mold module.

[0010] The upper die module and the lower die module of the utility model are further provided with matching guide holes or guide grooves and guide pins.

[0011] During operation, the utility model lays the carbon fiber composite material to be processed on the lower mold body. After the laying is completed, the lower mold body and the carbon fiber composite material are placed in the lower mold body limiting groove together. The pressure block is placed on the bottom plate of the lower mold template. The bottom plate is provided with a pressure block limiting block so that the pressure block can only move laterally. The guide pin is installed to the bottom plate by screws. Then the upper mold body is placed in the mold body limiting groove on the top plate and fixed with screws. The push block is placed in the top plate push block limiting groove and fixed with screws. The push block limiting plate on the top plate prevents the push plate from moving during the pressurization process. The rollover was caused by the broken screws. After the installation is completed, the lower mold module is placed on the flat plate, the upper mold module is placed on the lower mold module, the guide pin is inserted into the middle guide hole, and the molding tooling is placed on the press using the lifting ring. The press is closed from top to bottom to move the upper mold module downward. The upper inclined surface of the push block contacts the pressure block, and the pressure block moves from both sides to the middle, so that pressure can be applied in all four directions of up, down, left and right, until the upper mold module is tightly attached to the lower mold module and the pressure is completed. When demolding, you only need to lift the upper mold module and take out the pressure block to knock the product out.

[0012] Compared with the prior art, the utility model has the advantages of reasonable structure, easy assembly and disassembly, and can simultaneously subject the product to forces in four directions, namely, up, down, left and right, thereby obtaining a product with good internal quality, excellent mechanical properties and high dimensional accuracy.

[0021] As attached Figure 1 、 2 As shown, the utility model proposes a carbon fiber molding tool with pressure on all sides, which is provided with an upper mold module 2 and a lower mold module 1. The upper mold module 2 and the lower mold module 1 respectively have corresponding upper mold body limiting grooves 3 and lower mold body limiting grooves 4. After the upper mold module 2 and the lower mold module 1 are buckled together, the upper mold body limiting grooves 3 and the lower mold body limiting grooves 4 form a mold body cavity, and the mold body 5 is placed in the mold body cavity. A pressure block is also provided on the lower mold module 1, and the pressure block is located on the side of the lower mold body limiting groove 4. The side of the pressure block close to the mold body 5 is provided with an arc corresponding to the shape of the mold body 5, and the side of the pressure block away from the mold body 5 is an inclined surface. The upper mold module 2 is provided with a push block 18 relative to the pressure block, and the side of the push block 18 close to the mold body 5 is provided with a pushing inclined surface for cooperating with the outer inclined surface of the pressure block. After the upper mold module 2 and the lower mold module 1 are buckled together, the push block 18 presses down and pushes the pressure block close to the mold body 5.

[0022] The lower mold module 1 of the utility model is symmetrically provided with two pressure blocks around the lower mold body limiting groove 4. Correspondingly, the upper mold module 2 is provided with two push blocks 18 respectively cooperating with the two pressure blocks. Furthermore, the pressure block is movably connected to the bottom plate 11 of the lower mold module 1, and a pressure block limiting groove is provided on the bottom plate 11 of the lower mold module 1, and the pressure block is placed in the pressure block limiting groove; further, the push block 18 is movably connected to the upper mold module 2, and a push block limiting groove is provided on the top plate of the upper mold module 2, and corresponding screw holes are provided on the push block limiting groove and the push block, and the push block is fixed by screws.

[0023] In order to prevent the push block 18 from tipping over during mold closing and pressurizing, the present invention further provides a push block limit plate 6 on the upper mold module. The push block limit plate 6 is arranged on the outside of the push block 18 (i.e., the side away from the mold body) and is arranged parallel to the push block 18.

[0024] In order to ensure that the pressure block moves only toward the mold body 5 during the mold closing and pressurizing process, two pressure block limiting plates 7 are respectively provided at both ends of the bottom plate of the lower mold module 1 .

[0025] The upper die module 2 and the lower die module 1 of the present invention are further provided with matching guide holes or guide grooves 8 and guide pins 9 .

[0026] Example:

[0027] This example provides a four-sided pressurized carbon fiber molding tooling, comprising a lower mold module 1 and an upper mold module 2. The lower mold module 1 includes a bottom plate 11, a lower mold body 12, a pressurizing block A 13, a pressurizing block B 14, a lifting ring 15, and a guide pin 9. The upper mold module 2 includes a top plate 17, a push block 18, and an upper mold body 19. The bottom plate 11 is provided with a pressurizing block limiting plate 7, a lower mold body limiting groove 4, and a guide pin mounting groove. The top plate 17 is provided with a push block limiting plate 6, a push block limiting groove 10, an upper mold body limiting groove 3, and a guide hole 8.

[0028] When using, if attached Figure 5 As shown, first, the carbon fiber composite material 16 is laid on the lower mold body 19. After the laying is completed, the lower mold body 19 and the carbon fiber composite material 16 are placed together in the lower mold body limiting groove 4 of the bottom plate, and the lower mold body 19 is fixed to the bottom plate 11 with screws, and the pressure block A and the pressure block B are placed on the bottom plate 11. The bottom plate 11 is provided with a pressure block limiting plate 7 so that the pressure block can only move laterally, and the guide pin 9 is installed on the bottom plate 11 by screws; the upper mold body 19 is placed in the upper mold body limiting groove 3 of the top plate 17 and fixed with screws, and the push block 18 is placed in the top plate push block limiting groove 10 and fixed with screws. The push block limiting plate on the top plate prevents the push plate from tipping over due to screw breakage during the pressurization process; after the installation is completed, the lower mold module 1 is placed on the flat plate, the upper mold module 2 is placed on the lower mold module 1, and the guide hole is inserted into the 16 guide pins;

[0029] As attached Figure 6 As shown, the molding tool is placed on the press using a lifting ring 15. The press is then closed, causing the upper mold module 2 to move downward. The upper inclined surface of the push block 18 contacts the pressure blocks A and B, causing the pressure blocks to move from both sides toward the center, thereby achieving pressure in all four directions: up, down, left, and right. Pressurization is complete until the upper and lower mold modules are tightly attached. To demold, simply lift the upper mold module and remove the pressure blocks A 13 and B 14 to knock the product out.

[0030] Compared with the prior art, the utility model has the advantages of reasonable structure, easy assembly and disassembly, and can simultaneously subject the product to forces in four directions, namely, up, down, left and right, thereby obtaining a product with good internal quality, excellent mechanical properties and high dimensional accuracy.
