Description

Technical Field

[0001] This utility model relates to the field of forming mold technology, and in particular to T-beam forming mold. Background Technology

[0002] In the field of aircraft design, T-beams, as core load-bearing structural components, directly affect the structural strength, rigidity, and lightweight level of aircraft. To meet the triple requirements of "high strength, high rigidity, and lightweight," aviation T-beams are generally manufactured using composite materials through autoclave molding. With the synergistic effect of "vacuum degaussing + high-pressure gas pressurization + high-temperature curing," the prepreg ply blank can be densified and cured in a sealed tank, ultimately obtaining high-performance composite material components with low porosity and stable volume fraction. Before implementing the autoclave molding process, the assembly and positioning of the T-beam molding mold must be completed. The three prepreg ply molds must be precisely installed on the reference plate, and the core material is placed in the cavity enclosed by the molds to form a complete molding cavity. The fixing of the molds to the reference plate and between the molds often uses multiple sets of bolt connections. The bolt disassembly and assembly operations significantly extend the auxiliary process time and reduce the overall production efficiency. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1 Reference Figure 1 , Figure 2 as well as Figure 7 This is the first embodiment of the present invention. This embodiment provides a T-beam forming mold, which includes a main component 1, including a flat plate 11. A bottom forming mold 12 is provided on the flat plate 11, a side forming mold 13 is provided on one side of the bottom forming mold 12, and a layup mold 14 is provided on the upper end of the side forming mold 13. The flat plate 11 is a reference plate. The bottom forming mold 12, the side forming mold 13 and the layup mold 14 need to be pre-impregnated with liquid. During installation, the bottom forming mold 12 and the side forming mold 13 need to be installed on the flat plate 11 first, and then the core material is placed between the two. Then the layup mold 14 is installed on the side forming mold 13. The core material is located in the cavity enclosed by the three molds. Then the flat plate 11 is transferred to a hot autoclave for hot autoclave process. After cooling and demolding, a high-strength, high-rigidity and lightweight composite material T-beam can be obtained.

[0029] Mounting component 2, located on plate 11, includes mounting part 21. Mounting part 21 is set for assembling plate 11, bottom forming mold 12, side forming mold 13 and lay-up mold 14. There are two sets of mounting components 2, symmetrically distributed on both sides of plate 11, bottom forming mold 12, side forming mold 13 and lay-up mold 14, to lock the position of the components from both sides.

[0030] Mounting component 21 includes a first sleeve 211 fixed on a flat plate 11, a second sleeve 212 slidably disposed on the flat plate 11, a first positioning post 213 fixed on a side forming mold 13, the first positioning post 213 being insertable into the first sleeve 211, a third sleeve 214 fixed on a stacking mold 14, the third sleeve 214 being sleeved outside the first positioning post 213, and a second positioning post 215 fixed on a bottom forming mold 12, the second positioning post 215 being insertable into the second sleeve 212.

[0031] During installation, first insert the two first positioning posts 213 on the side forming mold 13 into the two first sleeves 211 on the plate 11. Then, adjust the position of the second sleeve 212 as needed. Next, insert the two second positioning posts 215 on the bottom forming mold 12 into the second sleeve 212. Then, place the core material on the side forming mold 13 and the bottom forming mold 12. Then, align the two third sleeves 214 on the stacking mold 14 with the first positioning posts 213 and fit them over the first positioning posts 213.

[0032] Example 2 Reference Figures 3-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, the mounting assembly 2 also includes a locking element 22 located inside the first positioning post 213. By setting the locking element 22, the relative position of the first positioning post 213 in the first sleeve 211 and the third sleeve 214 is locked, and the relative position of the second positioning post 215 in the second sleeve 212 is locked, thereby ensuring that the components will not separate.

[0034] The locking component 22 includes a lower locking block 221 slidably disposed within the first positioning post 213. A first locking groove 211-1 is provided in the first sleeve 211. Two lower locking blocks 221 are slidably disposed within the first positioning post 213, and the number of the first locking grooves 211-1 is the same. The lower locking blocks 221 can engage with the first locking grooves 211-1. Under the cooperation of the two, the relative position of the first positioning post 213 and the first sleeve 211 is restricted, thereby making the side forming mold 13 and the flat plate 11 stably connected.

[0035] A support plate 222 is fixed on the lower locking block 221, and an elastic pad 223 is fixed on the support plate 222. Two support plates 222 are fixed on each lower locking block 221. The two lower locking blocks 221 are elastically connected by the elastic pad 223. The elastic pad 223 can apply a continuous pushing force to the two lower locking blocks 221, ensuring that the lower locking block 221 can protrude from the side of the first positioning post 213 and engage with the first locking groove 211-1 when no other external force is applied. When subjected to external force, the elastic pad 223 can deform and be compressed. When the external force disappears, the elastic pad 223 can return to its original position.

[0036] The first positioning post 213 has a groove corresponding to the support plate 222 and the elastic pad 223. The groove cooperates with the support plate 222 to prevent the lower locking block 221 from separating from the first positioning post 213.

[0037] Specifically, two upper locking blocks 224 are slidably disposed inside the first positioning post 213, and an elastic pad 223 is also disposed between the upper locking blocks 224. A second locking groove 214-1 is opened inside the third sleeve 214. The two upper locking blocks 224 are elastically connected through the elastic pad 223. The upper locking blocks 224 can engage with the second locking groove 214-1. Through the cooperation of the two, the relative positions of the first positioning post 213 and the third sleeve 214 can be locked, ensuring that the side forming mold 13 and the stacking mold 14 can be stably connected.

[0038] Specifically, both the lower locking block 221 and the upper locking block 224 are inclined at one end, and the first locking groove 211-1 and the second locking groove 214-1 have corresponding shapes.

[0039] By tilting the design, when the first positioning post 213 is inserted into the first sleeve 211, the inclined surface of the lower locking block 221 will first contact the end face of the first sleeve 211 and be squeezed. The elastic pad 223 will be compressed, and the lower locking block 221 will be pushed and completely positioned inside the first positioning post 213, without obstructing the insertion of the first positioning post 213. As the insertion proceeds, after the lower locking block 221 is coaxial with the first locking groove 211-1, the elastic pad 223 will reset, pushing the locking block 221 to engage with the first locking groove 211-1, thereby limiting the relative position of the first positioning post 213 and the first sleeve 211, thus ensuring a stable connection between the side forming mold 13 and the flat plate 11.

[0040] When the third sleeve 214 is placed on the upper end of the first positioning post 213, the inclined surface of the upper locking block 224 will first contact the end face of the third sleeve 214. The inclined surface of the upper locking block 224 will be squeezed, the elastic pad 223 will be compressed, and the upper locking block 224 will be pushed and completely located inside the first positioning post 213, without hindering the movement of the third sleeve 214. When the upper locking block 224 is coaxial with the second locking groove 214-1, the elastic pad 223 will reset, pushing the upper locking block 224 to engage with the second locking groove 214-1. The upper locking block 224 will prevent the third sleeve 214 from moving upward away from the first positioning post 213, thereby limiting the relative position of the first positioning post 213 and the first sleeve 211, so that the side forming mold 13 and the plate 11 are stably connected.

[0041] Example 3 Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0042] Specifically, a lifting column 225 is slidably disposed inside the first positioning column 213. A connecting plate 226 is fixed on the lifting column 225. Two pressing blocks 227 are fixed on the connecting plate 226. The pressing blocks 227 are used to release the engagement between the lower locking block 221 and the first locking groove 211-1, and at the same time unlock the lock between the upper locking block 224 and the second locking groove 214-1. The connecting plate 226 is used to connect the two pressing blocks 227. When the lifting column 225 moves upward, it will drive the connecting plate 226 and the two pressing blocks 227 to move upward synchronously.

[0043] In the initial state, under the action of gravity, the lifting column 225 will be at the lowest position, and the squeezing block 227 will also be at the lowest position. At this time, the squeezing block 227 will not affect the movement of the lower locking block 221 into the first positioning column 213.

[0044] Specifically, one side of the extrusion block 227 is inclined, and the lower locking block 221 and the upper locking block 224 are both provided with inclined grooves 221-1, which can contact the inclined surface of the extrusion block 227.

[0045] When the extrusion block 227 moves upward, the inclined surface of the extrusion block 227 will fit against the inclined groove 221-1 and extrude the inclined groove 221-1, thereby causing the lower locking block 221 to move away from the first locking groove 211-1. When the two are completely separated, the position lock of the first positioning post 213 and the first sleeve 211 is released, and the side forming mold 13 and the flat plate 11 can be separated.

[0046] Four extrusion blocks 227 are fixed on the lifting column 225. The two extrusion blocks 227 located at the top are used to unlock the two lower locking blocks 221, while the two extrusion blocks 227 located at the bottom are used to unlock the upper locking block 224. When the lifting column 225 moves upward, the two lower extrusion blocks 227 move upward synchronously. Similarly, pressure is applied to the inclined groove 221-1 in the lower locking block 221, so that the upper locking block 224 gradually separates from the second locking groove 214-1, releasing the lock between the first positioning column 213 and the third sleeve 214, so that the side forming mold 13 and the stacking mold 14 can be separated.

[0047] Specifically, a lifting plate 228 is fixed on the lifting column 225, and a corresponding through groove is opened in the first positioning column 213. The two ends of the lifting plate 228 extend to the outside of the first positioning column 213, and the lifting plate 228 facilitates the operator to apply an upward force to the lifting column 225.

[0048] Specifically, the second positioning post 215 is also equipped with a lower locking block 221, a pressing block 227, a lifting post 225, and a lifting plate 228, and the number is the same as that in the first positioning post 213. The second sleeve 212 is also provided with a first locking groove 211-1. The locking structure of the second positioning post 215 and the second sleeve 212 is completely consistent with the locking structure and principle inside the first sleeve 211 and the first positioning post 213.

[0049] By moving the lifting plate 228 on the second positioning post 215 upward, the internal lifting post 225 can be moved upward, so that the extrusion block 227 contacts and extrudes the lower locking block 221 inside the second positioning post 215, and finally releases the lock between the second positioning post 215 and the second sleeve 212, so that the bottom forming mold 12 can be separated from the flat plate 11.

[0050] Specifically, a rectangular block 216 is fixed on the second sleeve 212, and a slider 217 is fixed on the plate 11. The rectangular block 216 slides within the slider 217. The slider 217 has a groove corresponding to the rectangular block 216. The rectangular block 216 slides within the groove, which can adjust the relative position of the second sleeve 212 and the first sleeve 211. This allows the distance between the side forming mold 13 and the bottom forming mold 12 to be changed as needed. The slider 217 has a threaded hole, and a bolt is threaded into the threaded hole. After the position of the second sleeve 212 is determined, the bolt is tightened. The end face of the bolt will gradually come into contact with the rectangular block 216. Under the action of friction, the position of the rectangular block 216 within the slider 217 will be locked, thereby locking the position of the second sleeve 212 on the plate 11.

[0051] Specifically, a base 15 is fixed to the bottom of the flat plate 11. The base 15 is provided with a lifting lug 16 and a forklift hole 17. The lifting lug 16 and the forklift hole 17 are provided to facilitate the movement of the entire mold.

[0052] During use, during installation, first insert the two first positioning pins 213 on the side forming mold 13 into the two first sleeves 211 on the plate 11. Then, adjust the position of the second sleeve 212 as needed and lock the position of the second sleeve 212 with bolts. Next, insert the two second positioning pins 215 on the bottom forming mold 12 into the second sleeve 212. Then, place the core material on the side forming mold 13 and the bottom forming mold 12. Finally, align the two third sleeves 214 on the stacking mold 14 with the first positioning pins 213 and fit them on the outside of the first positioning pins 213. At this time, the lower locking block 221 in the first positioning pin 213 engages with the first locking groove 211-1 in the first sleeve 211, and the upper locking block 224 in the first positioning pin 213 engages with the second locking groove 214-1 in the third sleeve 214. At the same time, the lower locking block 221 in the second positioning pin 215 will also engage with the first locking groove 211-1 in the second sleeve 212, thereby completing the installation of the overall mold.

[0053] After molding is completed, the operator moves the lifting plate 228 located inside the first positioning post 213 upwards, causing the lifting post 225 to move upwards. The connecting plate 226 and the two extrusion blocks 227 move upwards simultaneously. The inclined surface of the extrusion block 227 will fit against the inclined groove 221-1 and extrude pressure against the inclined groove 221-1, thereby causing the lower locking block 221 to move away from the first locking groove 211-1. When the two are completely separated, the position lock of the first positioning post 213 and the first sleeve 211 is released, and the side forming mold 13 can be separated from the flat plate 11. At the same time, the two extrusion blocks 227 below move upwards simultaneously, and the pressure will be released. Pressure is applied to the inclined groove 221-1 in the lower locking block 221, causing the upper locking block 224 to gradually separate from the second locking groove 214-1, releasing the lock between the first positioning post 213 and the third sleeve 214, so that the side forming mold 13 and the stacking mold 14 can be separated. Then, the operator moves the lifting plate 228 located in the second positioning post 215 upward, driving the internal lifting post 225 upward, so that the extrusion block 227 contacts and extrudes the lower locking block 221 in the second positioning post 215, finally releasing the lock between the second positioning post 215 and the second sleeve 212, so that the bottom forming mold 12 can be separated from the flat plate 11.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
