Description

Technical Field

[0001] This invention relates to the field of air intake forming tooling technology, specifically to a flanged composite material air intake forming tooling. Background Technology

[0002] Composite materials, with their advantages of being lightweight, high-strength, having excellent thermal stability, and being highly designable, have been widely used in aerospace, military, and other fields. Typical applications include core components such as rocket fairings, UAV fuselages, and missile bodies. Based on the structural characteristics of composite materials, their applications have expanded from simple structural forms like skins and ribs to complex structures. As the aerospace industry continues to demand higher aerodynamic performance, some complex, irregularly shaped metal products are gradually being replaced by composite materials. These irregularly shaped composite material parts present technical challenges in structural design and manufacturing processes. They not only need to meet the requirements for smooth and flat inner and outer surfaces, but also require structural integration through an integrated molding process.

[0003] Traditional mandrel molding methods, which use soluble mandrels as inner surface supports for prepreg stacking, can solve the demolding problem of complex internal cavities. However, after the parts are cured, the mandrels need to be dissolved and removed by means of water immersion, which takes a long time. The dissolved waste liquid is prone to chemical pollution, increasing environmental protection costs. Moreover, it is very easy to scratch the inner wall of the product or even cause the component to tear during demolding. In addition, some soluble mandrel materials may react chemically with the resin matrix during high-temperature curing, affecting the mechanical properties of the composite material. Summary of the Invention

[0004] The present invention aims to solve the problem that the traditional demolding method for integral molding of parts with irregular cavities has a long melting process and the melting waste liquid is prone to chemical pollution.

[0005] To address the aforementioned problems, this invention provides a flanged composite material intake duct forming fixture, comprising a core module for forming the inner forming surface of the intake duct component. The core module has a relatively upper first end face and a relatively lower second end face along its length. The core module includes several outer core molds, each extending from the first end face towards the second end face. After the several outer core molds are assembled, their outer wall surfaces are combined to form the inner forming surface of the intake duct component. A straight cavity is formed inside the assembled several outer core molds. One end of the straight cavity penetrates the first end face, and the other end penetrates the second end face. The straight cavity is used to remove each outer core mold from the intake duct component, and an inner core mold is inserted into the straight cavity.

[0006] A first baffle is provided at the first end face, and a second baffle is provided at the second end face. The first baffle is detachably fixed to the corresponding end of the corresponding outer core mold / inner core mold, or the second baffle is detachably fixed to the corresponding end of the corresponding outer core mold / inner core mold.

[0007] As a further aspect of the present invention, it also includes a base body, on which a connecting end adapted to the second baffle and a recessed portion adapted to the flanged structure of the air intake component are formed. A cavity is formed inside the base body. The second baffle is detachably fixed to the connecting end by a connector. One end of the connector passes through the connecting end and extends into the cavity. The cavity is used to remove the connector when separating the second baffle and the connecting end.

[0008] As a further aspect of the present invention, it also includes a base plate, on which a support structure is provided below the first end face. The support structure is used to fix the core module to the base plate through the first end face, and the base body is detachably fixed to the base plate.

[0009] As a further aspect of the present invention: the base body includes a first base and a second base, the first base is located on the lower side of the second end face, and the first base and the second base are detachably fixed together.

[0010] As a further aspect of the present invention: an auxiliary positioning component is placed on the base body, and an arc surface is formed on the auxiliary positioning component to adapt to the connection between the upper cylinder of the air intake component and the flange structure.

[0011] As a further aspect of the present invention: a first groove is formed on part / all of the outer core mold, the first groove not penetrating the outer wall surface of the outer core mold that contacts the air intake component.

[0012] As a further aspect of the present invention: a plurality of second grooves are formed on the inner core mold.

[0013] As a further aspect of the present invention: several lifting lugs are fixed on the symmetrical sides of the base body.

[0014] As a further aspect of the present invention: the support structure includes a plug rod fixed under the first baffle and a fork rod fixed on the base plate, wherein the plug rod and the fork rod are detachably fixed together.

[0015] As a further aspect of the present invention: several support plates are fixed on the base plate on two symmetrical sides of the base body, and positioning holes are provided on the base body at corresponding positions.

[0016] The present invention provides a flanged composite material air intake forming tooling, which, compared with the prior art, has the following beneficial effects, but is not limited to:

[0017] By redesigning the intake manifold forming tooling, a hard, non-soluble structure can be used as the core mold for the intake manifold component. After forming, it can also be removed from the complex forming surface inside the intake manifold component. This process avoids chemical pollution and the waiting period for the core mold to dissolve from the source. Therefore, compared with the traditional intake manifold component forming method, the demolding speed after forming is faster, reducing environmental protection costs and avoiding potential chemical pollution problems. Furthermore, when forming composite materials, the core mold will not react with the composite material at high temperatures, ensuring the mechanical properties of the intake manifold formed using composite materials.

[0033] like Figure 1 , 2 As shown in Figure 4, a flanged composite material intake duct forming fixture includes a core module 1, which forms the inner forming surface of the intake duct component 4. The core module 1 has a relatively upper first end face 11 and a relatively lower second end face 12 along its length. The core module 1 includes a plurality of outer core molds 13, each of which extends from the first end face 11 to the second end face 12. After the plurality of outer core molds 13 are assembled, the collection of their outer wall surfaces forms the inner forming surface of the intake duct component 4. The assembled interior forms a straight cavity, one end of which penetrates the first end face 11 and the other end of which penetrates the second end face 12. The straight cavity is used to remove each outer core mold 13 from the air intake component 4. An inner core mold 14 is inserted into the straight cavity. A first baffle 2 is provided at the first end face 11 and a second baffle 3 is provided at the second end face 12. The first baffle 2 is detachably fixed to the corresponding end of the corresponding outer core mold 13 / inner core mold 14, or the second baffle 3 is detachably fixed to the corresponding end of the corresponding outer core mold 13 / inner core mold 14.

[0034] In this embodiment, when the intake duct component 4 is formed, the outer core mold 13 in the core module 1 can form the inner forming surface of the intake duct component 4 when they are assembled accordingly. Therefore, the shape of the outer core mold 13 can be adjusted and changed to adapt to the forming of intake duct components 4 with different inner forming surfaces.

[0035] Since the core module 1 remains inside the intake duct component 4 after molding and hardening, and since the intake duct component 4 has a certain curvature, it is difficult to remove the core module 1 from the core module 1 after the intake duct component 4 has been molded and hardened if it is integrally molded. Therefore, the core module 1 is split into a combination of several outer core molds 13, and each outer core mold 13 extends from the first end face 11 to the second end face 12, so that it can be removed from the openings at both ends of the intake duct component 4 when it is possible to remove it.

[0036] To satisfy a condition that allows several outer core molds 13 to be removed from the intake duct component 4, namely, that the outer core molds 13 to be removed have a certain adjustment space within the intake duct component 4, a straight cavity is formed within the structure after the several outer core molds 13 are assembled. The trajectory of the straight cavity extends from the first end face 11 of the outer core mold 13 to the second end face 12, and the two ends respectively penetrate the corresponding first end face 11 and second end face 12. Since the purpose of forming this straight cavity is to allow at least one outer core mold 13 to be removed outward from this space, the space it forms must meet the adjustment requirements of several outer core molds 13. In this state, if multiple outer core molds 13 are directly assembled, the outer core mold 13 whose adjustment requirements are met is prone to leaking into the straight cavity, making the core mold group 1 structure formed by the assembly not stable enough.

[0037] Therefore, an inner core mold 14 is formed in the straight cavity to support each outer core mold 13 outward in the straight cavity, preventing the outer core mold 13 from falling into the straight cavity. Secondly, since the cavity is straight, unlike the inner forming surface of the intake duct component 4 which has several curved surfaces and arcs, when it is necessary to remove the core mold assembly 1 from the intake duct component 4, the inner core mold 14 can be removed outward along the straight cavity first, and then the space of the straight cavity can be used to remove the outer core mold 13 that meets the adjustment requirements. After that, as the outer core mold 13 is removed, the space in the intake duct component 4 that is connected to the straight cavity becomes larger, and the difficulty of removing the remaining outer core mold 13 is further reduced, and it can be removed more conveniently until the last outer core mold 13 is removed.

[0038] It should be noted that during this process, after the inner core mold 14 is removed from the straight cavity, the space of the straight cavity should at least meet the requirement that one of the outer core molds 13 can be adjusted and removed from the intake duct component 4. After all the outer core molds 13 that can be removed from the space of the straight cavity are removed from the intake duct component 4, the newly enlarged cavity formed in communication with the straight cavity should at least meet the removal conditions of at least one of the outer core molds 13 that have not yet been removed. The above process is then repeated. After the second batch of outer core molds 13 are removed, the further enlarged cavity should at least meet the removal conditions of at least one of the remaining outer core molds 13. The above steps are repeated until the last outer core mold 13 is removed from the intake duct component 4. In order to ensure this process, all outer core molds 13 are constructed to be able to be freely inserted into or removed from the hardened intake duct component 4.

[0039] Meanwhile, by simply disassembling the core module 1, the requirement to remove it from the hardened intake duct component 4 can be met. However, during the molding process, in order to ensure the stable assembly of the outer core mold 13 and the inner core mold 14 in the core module 1, a first baffle 2 and a second baffle 3 are respectively provided on the first end face 11 and the second end face 12 formed by the core module 1. This allows the corresponding ends of the outer core mold 13 / inner core mold 14 to be detachably fixed on the corresponding first baffle 2 or second baffle 3. In this way, the core module 1 is shaped by the first baffle 2 and the second baffle 3, which can ensure the stability of the core module 1 during the molding process. Moreover, since it is fixed on the end face, the fixed structure will not penetrate the outer wall surface of each outer core mold 13, so it will not affect the shape of the inner molding surface of the molded intake duct component 4. In summary, by redesigning the intake manifold forming tooling, a hard, non-soluble structure can be used as the core mold for the intake manifold component 4. After forming, it can also be removed from the complex forming surface inside the intake manifold component 4. This process avoids chemical pollution and the waiting period for the core mold to dissolve from the source. Therefore, compared with the traditional forming method for the intake manifold component 4, the demolding speed after forming is faster, reducing environmental protection costs and avoiding potential chemical pollution problems. Furthermore, when forming composite materials, the core mold will not react with the composite material at high temperatures, ensuring the mechanical properties of the intake manifold formed using composite materials.

[0040] Common intake duct components 4 have complex irregular cavity structures, often with recesses, variable cross sections, or negative angles. If the irregular cavity also has a flange, it will further increase the molding difficulty of such parts. Therefore, it is difficult to integrally mold the cylindrical part and the flanged part of common intake duct components 4.

[0041] like Figure 1-3As shown, optionally, it also includes a base body 5, on which a connecting end 51 adapted to the second baffle 3 and a recess 52 adapted to the flange structure 41 on the air intake component 4 are formed. A cavity 53 is formed inside the base body 5. The second baffle 3 is detachably fixed to the connecting end 51 by a connector 6. One end of the connector 6 passes through the connecting end 51 and extends into the cavity 53. The cavity 53 is used to remove the connector 6 when separating the second baffle 3 and the connecting end 51.

[0042] In this embodiment, when the required air intake component 4 is connected with a flange structure 41, if the core mold adopts an integral structure, due to the presence of the flange, the core mold must also have a flange forming structure to form the flange. Therefore, the shape of the core mold itself will be more complex, and it will be completely impossible to detach from the air intake component 4 when demolding is required. Therefore, based on the structure of the core mold assembly 1, a base body 5 is further added. The base body 5 has a recess 52 adapted to form the flange structure 41 on the air intake component 4. At the same time, a connecting end 51 for fixing the second baffle 3 is also formed. When the air intake component 4 with flange needs to be formed, the second baffle 3 is fixed to the connecting end 51 by the connector 6. After molding, the second baffle 3 needs to be disassembled to allow the outer core molds 13 and inner core molds 14 in the core module 1 to be removed from the air intake component 4. At this time, the second baffle 3 is connected to the base body 5, and the overall size of the base body 5 is much larger than the internal space of the air intake component 4. Therefore, the second baffle 3 cannot be disassembled from the base body 5. To solve this problem, one end of the connector 6 used to connect the second baffle 3 passes through the connecting end 51 and extends into the cavity 53 reserved at the bottom of the base body 5. At this time, the connector 6 can be removed from the bottom of the base body 5 to deconnect the second baffle 3 from the connecting end 51, thereby separating the base body 5 and the second baffle 3. The connector 6 can be configured as a fastener, such as a screw or threaded rod.

[0043] like Figure 1 As shown, optionally, it also includes a base plate 7, on which a support structure 71 is provided below the first end face 11. The support structure 71 is used to fix the core module 1 to the base plate 7 through the first end face 11, and the base body 5 is detachably fixed to the base plate 7.

[0044] In this embodiment, since there is a certain angle between the cylindrical part 42 and the flange structure 41 forming the air intake component 4, the core module 1 forming the air intake component 4 also needs to be connected to the base body 5 at a certain angle to achieve this angle. When the angle is large, since the core module 1 is only connected and fixed to the connecting end 51 by the second baffle 3, one end of the first baffle 2 is suspended upward, and the overall structure is not stable enough. Therefore, a support structure 71 is provided to provide support for the core module 1 at the first baffle 2 to improve its stability after fixing.

[0045] like Figure 2 As shown, optionally, the base body 5 includes a first base 54 and a second base 55. The first base 54 is located on the lower side of the second end face 12, and the first base 54 and the second base 55 are detachably fixed together.

[0046] In this embodiment, the base body 5 is split into a first base 54 and a second base 55, with the first base 54 located on the side below the second end face 12. This allows the first base 54, which is less connected to the hardened air intake component 4, to be disassembled first from the side of the flange structure 41 during demolding, which helps to reduce the overall weight of the base body 5. Since the connection between the second baffle 3 and the connecting end 51 needs to be removed through the cavity 53 later, the entire base body 5 needs to be suspended by the lifting lug 56. Separating the first base 54 and the second base 55 facilitates the suspension operation.

[0047] like Figure 1 and 2 As shown, optionally, an auxiliary positioning component 8 is placed on the base body 5, and the auxiliary positioning component 8 has an arc surface that adapts to the connection between the upper cylinder 42 of the air intake component 4 and the flange structure 41.

[0048] In this embodiment, when some intake duct components 4 have a flange structure 41, there will be a connection gap between the cylindrical part 42 and the flange structure 41. When the prepreg needs to be attached to the outside of the core module 1, the gap is small and difficult to meet the molding requirements. Moreover, it may expand outward during the curing process. Therefore, an auxiliary positioning part 8 is placed at this location. By means of the arc surface of the connection between the cylindrical part 42 and the flange structure 41, it is forced to exert a certain squeezing force on the prepreg in the gap on one side, which is sufficient to avoid deformation of the prepreg during the curing process and ensure the external quality of the intake duct component 4 during molding.

[0049] like Figure 2 As shown, optionally, a first groove 131 is formed on part / all of the outer core mold 13, and the first groove 131 does not penetrate the outer wall surface of the outer core mold 13 that contacts the air intake component 4.

[0050] In this embodiment, the first groove 131 is used to reduce the mass of the outer core mold 13, and the first groove 131 is also prevented from penetrating the outer wall surface, which can also prevent it from affecting the shape of the inner forming surface of the air intake component 4, thus helping to reduce costs.

[0051] like Figure 2 As shown, optionally, a plurality of second grooves 141 are formed on the inner core mold 14.

[0052] In this embodiment, the second groove 141 is also used to reduce the mass of the outer core mold 13.

[0053] like Figure 1 and 2 As shown, optionally, several lugs 56 are fixed on the symmetrical sides of the base body 5.

[0054] In this embodiment, the lifting lug 56 is used to facilitate lifting the entire base body 5 after the air intake component 4 has been cured and molded, making demolding easier.

[0055] like Figure 1 and 2 As shown, optionally, the support structure 71 includes a rod 711 fixed under the first baffle 2 and a fork rod 712 fixed on the base plate 7, and the rod 711 and the fork rod 712 are detachably fixed together.

[0056] In this embodiment, when it is necessary to fix the core module 1, the insert rod 711 is inserted into the fork rod 712 and fixed detachably by fastener connection. This facilitates the support of the core module 1 at the first end face 11 and maintains its stability during the curing process.

[0057] like Figure 1 As shown, optionally, several support plates 72 are fixed on the base plate 7 on two symmetrical sides of the base body 5, and positioning holes are opened on the base body 5 at corresponding positions.

[0058] In this embodiment, the support plate 72 is disposed on both sides of the base body 5 and can be fixed to the base body 5 by fasteners passing through the positioning holes, so as to facilitate the stable fixing of the base body 5 to the base plate 7 for forming. At the same time, the support structure 71 on the base plate 7 further supports the first baffle 2, thereby further improving the stability of the intake duct component 4 during forming.

[0059] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
