As shown in fig. 1-10, a forming mold capable of reducing burrs at an opening during forming of a carbon fiber box body comprises a main mold 1, an inflatable elastic inner mold 2 and a cover plate 3, wherein an inner cavity for laying a carbon fiber cloth 100 (resin is coated on the surface of the carbon fiber cloth 100) and having an open upper end is arranged in the middle of the main mold 1, and the inflatable elastic inner mold 2 is arranged in the inner cavity of the main mold 1 and can compress and shape the carbon fiber cloth 100 through inflation; the forming die also comprises a pressing block 4; a step 11 surrounding the inner cavity of the main die 1 is arranged on the inner wall of the upper end of the main die 1; the pressing block 4 is detachably mounted on the step 11, the inner side of the pressing block 4 extends inwards out of the inner wall of the main die 1 to be attached to the top surface of the carbon fiber cloth 100, and preferably, the distance that the inner side of the pressing block 4 extends inwards out of the inner wall of the main die 1 is equal to the thickness of the carbon fiber cloth 100; the cover plate 3 is fixed above the main mold 1, and specifically, the main mold 1 and the cover plate 3 are fixedly connected through screws. Specifically, the compact 4, the main mold 1, and the cover plate 3 are made of metal. The pressing block 4 may be directly placed in the step 11 or may be screwed with the main mold 1, which is not limited in this respect. In this embodiment, the inflation of the inflatable elastic inner mold 2 may be performed by using an air inlet channel which is arranged on the cover plate 3 and connected with an air source, and as long as an outlet of the air inlet channel is communicated with an inner cavity of the inflatable elastic inner mold 2, it should be noted that the inflatable elastic inner mold 2 is not only a type in the drawings, but also may be replaced by an air bag or an air bag, and the like, and here, it is not specifically limited, and it is only required to shape the carbon fiber cloth 100 in the forming process of the carbon fiber cloth 100, and in this embodiment, the inflatable elastic inner mold 2 is an elastic inner mold which has an inner cavity in the middle and an opening at the upper end. According to the invention, the inflatable elastic inner die 2 is inflated to expand, so that the carbon fiber cloth 100 laid in the main die 1 can be shaped, and then the bottom surface of the inner side of the pressing block 4 is matched and attached to the top surface of the carbon fiber cloth 100, so that vertical burrs (in the direction from bottom to top of the box body in the figure 10) can not appear at the opening 200 of the carbon fiber cloth 100 after the carbon fiber cloth 100 is shaped, thereby saving the trimming time of workers and improving the working efficiency.
As shown in fig. 5, 7 and 9, an opening 41 is provided in the middle of the pressing block 4; the upper end of the inflatable elastic inner die 2 extends to the upper part of the pressing block 4 through the opening 41 and is correspondingly arranged in a positioning step 12 which is positioned on the main die 1 and surrounds the inner cavity of the main die 1; the cover plate 3 compresses and fixes the upper end of the inflatable elastic inner die 2, the bottom surface and the top surface of the upper end of the inflatable elastic inner die 2 are respectively contacted with the main die 1 and the cover plate 3, and the contact part is a sealing structure, specifically, as shown in fig. 5, the upper end of the inflatable elastic inner die 2 is an outward extending outer edge, the inflatable elastic inner die 2 is installed in the positioning step 12 through the outer edge and is compressed and fixed by the cover plate 3, and a person skilled in the art should know that the outer edge has elasticity, so the sealing between the outer edge and the main die 1 and the cover plate 3 can be realized only by setting the thickness of the outer edge to be slightly larger than the height of the positioning step 12; the bottom surface of the step 11 is provided with a vacuumizing diversion trench 14 which surrounds the inner cavity of the main die 1 and is communicated with an air outlet channel 13 arranged on the main die 1. After the air outlet channel 13 is connected with an air extractor, air between the carbon fiber cloth 100 and the inflatable elastic inner die 2 and air between the carbon fiber cloth 100 and the inner wall of the main die 1 can flow to the vacuum guide channel 14 through a gap between the bottom surface of the pressing block 4 and the main die 1 by utilizing the vacuum guide channel 14 and the air outlet channel 13 which are communicated with each other, and finally, the air is discharged from the air outlet channel 13; meanwhile, the redundant resin generated by extrusion of the carbon fiber cloth 100 in the forming process can also flow to the vacuumizing diversion trench 14 through the gap between the bottom surface of the pressing block 4 and the main die 1, and is discharged from the air outlet channel 13 to form vacuum among the carbon fiber cloth 100, the main die 1 and the inflatable elastic inner die 2, so that the carbon fiber cloth 100 is better attached to the lower die 1, and the wall surface of the formed box body is smoother.
Specifically, as shown in fig. 9, the bottom surface of the briquette 4 is provided with a vent groove 42 penetrating the inner wall and the outer wall of the briquette 4, and preferably, the vent groove 42 is provided with a plurality of vent grooves 42 distributed around the briquette 4. The provision of the vent grooves 22 accelerates the flow of air and excess resin, thereby improving the work efficiency.
As shown in fig. 7, a flow guide hole 15 is formed on the bottom surface of the step 11 and is respectively communicated with the vacuuming flow guide groove 14 and the air outlet channel 13; the diameter of the diversion hole 15 is larger than the width of the vacuumizing diversion trench 14 and the diameter of the air outlet channel 13. The air and the excess resin can be more smoothly flowed by providing the guide holes 15.
Specifically, when the carbon fiber cloth cutting device is used, the press block 4 is installed, then the cut carbon fiber cloth 100 is laid on the inner wall of the main die 1, and the top surface of the carbon fiber cloth 100 is matched and attached with the bottom surface of the inner side of the press block 4; then the inflatable elastic inner mold 2 and the cover plate 3 are installed; then, a certain amount of compressed air is fed into the inner cavity of the inflatable elastic inner mold 2 to expand the inflatable elastic inner mold 2 so as to complete the shaping of the carbon fiber cloth 100; then, the forming die is heated, and the air outlet channel 13 is connected with an air extractor to extract air while heating, so that air and redundant resin between the carbon fiber cloth 100 and the inflatable elastic inner die 2 and air and redundant resin between the carbon fiber cloth 100 and the main die 1 flow out of the air outlet channel 13 through the vacuumizing diversion trench 14, the air extracting time of the air extractor is not too long, and otherwise the quality of a product is easily influenced; after the forming die is heated for a certain time to enable the carbon fiber cloth 100 to be fixedly formed, the whole forming die is cooled and demoulded to obtain the carbon fiber box body shown in the figure 10, and vertical burrs cannot occur at the opening 200 of the carbon fiber box body, so that the time for trimming the edges of workers is saved, and the production efficiency of the workers is improved.
The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
