Description

Technical Field

[0001] This utility model relates to the field of duct shell technology, and in particular to a co-curing molding mold for duct shells. Background Technology

[0002] As a crucial structural component in aviation, aerospace, and high-end equipment, the performance and quality of ducted casings significantly impact the stability and safety of the overall system. Therefore, developing efficient and high-precision ducted casing molding dies is of paramount importance.

[0003] Currently, most culvert shells are manufactured using a segmented forming method, where the outer wall of the culvert is formed separately, and then the culvert shell is assembled by combining it with the internal structure. This assembly-type manufacturing method has problems such as difficulty in connecting and positioning the internal structure with the outer wall of the culvert, low assembly positioning accuracy, and poor strength and rigidity of the resulting culvert shell, which affects the stability and safety of the overall system.

[0004] Therefore, there is an urgent need for a co-curing molding die for duct housings to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a co-curing mold for duct shells, which can efficiently manufacture duct shells with good overall rigidity and strength.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The duct housing co-curing molding die includes:

The internal cavity can hold the stator blades, and one end of the stator blades can pass through the through-hole and be fixedly connected to the carbon fiber material to form a duct housing.

[0010] Preferably, the internal cavity includes at least one radial cavity portion, each of which is connected to one of the through ports. The clamping assembly can extend into the radial cavity portion and define a blade mounting space, which is used to limit and accommodate the stator blade.

[0011] Preferably, the mold body is provided with a first contouring recess, which is located on the inner wall of the radial cavity away from the mounting opening. The first contouring recess is used to accommodate and fit the portion of the stator blade that is positioned.

[0012] Preferably, the continuous outer wall is provided with a second contoured recess, which is located at the passage and is used to accommodate and fit the flange portion of the stator blade.

[0013] Preferably, the internal cavity further includes a central cavity located at the center of the mold body, and a radial cavity located between the central cavity and the circumferential outer wall, with the radial cavity and the central cavity communicating with each other.

[0014] The clamping assembly includes a positioning mandrel and a clamping member. The positioning mandrel can be positioned in the central cavity, and the clamping member can be positioned in the radial cavity. The positioning mandrel can abut against and limit the stator blade in the direction toward the circumferential outer wall.

[0015] Preferably, the positioning mandrel and the clamping member are provided with positioning pins, and the mold body is provided with positioning pin holes. The positioning pins can be inserted into the positioning pin holes to limit the connection between the positioning mandrel and the clamping member and the mold body.

[0016] Preferably, the mold body is provided with a threaded hole, the positioning mandrel and the clamping member are respectively provided with through holes, and the duct housing co-curing mold further includes a threaded connector, which can pass through the through hole and be threadedly connected to the threaded hole.

[0017] Preferably, one end of the positioning mandrel is provided with a frustum portion, and the diameter of the frustum portion gradually increases along the direction close to the other end of the positioning mandrel;

[0018] The inner wall of the central cavity includes a tapered limiting surface, which can fit against the outer peripheral surface of the frustum to limit the positioning mandrel.

[0019] Preferably, the positioning mandrel includes a circumferential abutment portion, which is used to limit and abut the stator blade in a direction toward the circumferential outer wall, and the clamping member and the circumferential abutment portion can clamp and limit the flange portion of the stator blade.

[0020] Preferably, the positioning mandrel has a stepped surface that can abut against the stator blade in a direction close to the mounting opening. The mold body has an ejection hole with an ejection shaft passing through it. The ejection shaft can be limited to abut against the positioning mandrel to eject the positioning mandrel and the duct housing simultaneously.

[0021] The beneficial effects of this invention are as follows: The stator blades can be fixed in the mold using this co-curing molding die for the duct housing, and the stator blades and carbon fiber material can be easily combined, thus integrally molding the duct housing. This ensures the strength and rigidity of the duct housing and improves the stability and safety of the overall system. Furthermore, the clamping assembly allows for precise positioning between the stator blades and the carbon fiber material, avoiding low assembly positioning accuracy. Attached Figure Description

[0036] The following is based on the appendix Figure 1 To be continued Figure 6 This invention introduces the co-curing molding die for duct housings provided by this utility model.

[0037] like Figures 1 to 3As shown, in this embodiment, the co-curing molding die for the duct housing includes a die body 1, a clamping assembly 2, and an ejection assembly. The die body 1 and the clamping assembly 2 are fixedly connected to secure the stator blades 100. The die body 1 has a circumferential outer wall 13, and the circumferential outer wall 13 and the clamping assembly 2 can be combined to form a continuous outer wall, which can be wound with shaped carbon fiber material. After co-curing, the carbon fiber material can be integrated with the stator blades 100 to form a single structure, thereby forming the duct housing. The ejection assembly has an ejection shaft that extends into the die body 1 to eject the formed duct housing from the die body 1, thus reducing demolding difficulty and improving production efficiency.

[0038] Specifically, in this embodiment, the mold body 1 has an internal cavity 11, and the circumferential outer wall 13 is provided with four through ports 113, which are connected to the internal cavity 11. Four stator blades 100 can be placed in the internal cavity 11, and each stator blade 100 can be exposed to the mold body 1 through a corresponding through port 113. An installation opening 12 is provided at the end of the mold body 1 away from the ejector assembly, and the installation opening 12 is connected to the internal cavity 11. The stator blades 100 and the clamping assembly 2 can enter the mold body 1 through the installation opening 12. The clamping assembly 2 can fill the through ports 113, thereby combining with the circumferential outer wall 13 to form a continuous outer wall.

[0039] Carbon fiber material can be wound and attached to a continuous outer wall, and connected to the portion of the stator blade 100 exposed in the mold body 1. After co-curing, the carbon fiber material can be integrated with the exposed portion of the stator blade 100 to form a duct housing. An ejection hole is provided at one end of the mold body 1 near the ejection assembly. An ejection shaft can extend into the mold body 1 through the ejection hole and apply an external force toward the mounting opening 12 to the duct housing, so that the duct housing can leave the mold body 1 through the mounting opening 12 after molding.

[0040] In use, for example, the stator blade 100 and the clamping assembly 2 are placed into the internal cavity 11 through the mounting opening 12, and the clamping assembly 2 and the mold body 1 are fixedly connected, so that the clamping assembly 2 clamps and fixes the stator blade 100. Then, carbon fiber material is wound on the continuous outer wall (this part forms the duct outer wall after curing), and then co-curing treatment is performed to make the carbon fiber material and the stator blade 100 bond together to form a duct shell. Then, the clamping assembly 2 and the mold body 1 are separated, and the duct shell can be ejected from the mold by the ejection assembly.

[0041] The stator blades 100 can be fixed in the mold using this co-curing molding die for the duct housing, and the stator blades 100 and carbon fiber material can be easily combined, thus integrally molding the duct housing. This ensures the strength and rigidity of the duct housing and helps improve the stability and safety of the overall system. Furthermore, the clamping assembly 2 can precisely position the stator blades 100 and the carbon fiber material, thereby avoiding the phenomenon of low assembly positioning accuracy.

[0042] like Figure 3 As shown, in this embodiment, the mold body 1 includes a base 14, a columnar portion 15, and four sector-shaped portions 16. The base 14 is fixedly disposed above the ejector assembly, the columnar portion 15 is fixedly connected to the top of the base 14, and four sector-shaped portions 16 are fixedly connected to the top of the columnar portion 15. The four sector-shaped portions 16 are circumferentially arranged around the axis of the columnar portion 15 and are centrally rotationally symmetrical about the axis of the columnar portion 15. An internal cavity 11, a passage 113, and a mounting opening 12 are defined between the four sector-shaped portions 16, allowing the stator blades 100 and the clamping assembly 2 to be inserted between the sector-shaped portions 16 and fixedly connected to either the sector-shaped portion 16 or the columnar portion 15.

[0043] Specifically, in this embodiment, the internal cavity 11 includes four radial cavities 112, each radial cavity 112 being used to limit and accommodate one stator blade 100. For example... Figure 3 As shown, a radial cavity 112 and a corresponding through-hole 113 are formed between two adjacent sector portions 16 in the circumferential direction of the columnar portion 15. The through-hole 113 connects to the end of the radial cavity 112 away from the axis of the columnar portion 15 in the radial direction. When the clamping assembly 2 enters the internal cavity 11 and is installed in place, a blade mounting space is defined between the clamping assembly 2 and the radial cavity 112. This blade mounting space can accommodate the stator blade 100, thereby precisely positioning the stator blade 100 at a predetermined position within the mold body 1.

[0044] Preferably, refer to Figures 1 to 3 As shown, along the axial direction of the columnar portion 15, the columnar portion 15 has a recessed first contoured recess 151. When the stator blade 100 is placed in the radial cavity 112, a portion of the stator blade 100 near the ejection assembly can be embedded in the first contoured recess 151, thereby avoiding interference between the stator blade 100 and the columnar portion 15. Simultaneously, due to the contoured structure, the first contoured recess 151 can fit snugly against the stator blade 100, facilitating more precise positioning of the stator blade 100.

[0045] Furthermore, a second contoured recess is provided on the continuous outer wall. This second contoured recess is located at the passage 113 and can accommodate and fit a flange portion 1001 of the stator blade 100. The second contoured recess can also prevent interference between the stator blade 100 and the mold body 1 or the clamping assembly 2, and can improve the positioning accuracy of the stator blade 100. Optionally, in this embodiment, according to the shape of the flange portion 1001 of the stator blade 100, a first recessed contour 160 is provided on the circumferential outer wall 13 of the mold body 1, and a second recessed contour 210 is provided on the clamping assembly 2. When the clamping assembly 2 is inserted into the radial cavity 112 and installed in place, the first recessed contour 160 and the second recessed contour 210 combine to form the aforementioned second contoured recess.

[0046] Continue to refer to Figure 3 As shown, in this embodiment, the internal cavity 11 further includes a central cavity 111. Along the radial direction of the columnar portion 15, the central cavity 111 is formed between a plurality of fan-shaped portions 16 and is located at the center of the mold body 1. A radial cavity 112 is located between the central cavity 111 and the circumferential outer wall 13, and the radial cavity 112 and the central cavity 111 are connected to form the aforementioned internal cavity 11.

[0047] like Figures 4 to 6 As shown, the clamping assembly 2 includes a clamping member 21 and a positioning mandrel 22. The clamping member 21 is positioned within the radial cavity 112 and forms a blade mounting space between itself and the inner wall of the radial cavity 112, thereby clamping and fixing the stator blade 100. The positioning mandrel 22 is positioned within the central cavity 111 and includes a circumferential abutment portion 221. The circumferential abutment portion 221 abuts against and positions the stator blade 100 in the direction toward the circumferential outer wall 13, thereby preventing abnormal radial movement of the stator blade 100 along the columnar portion 15 during the integral molding process and ensuring the strength and rigidity of the duct housing.

[0048] Preferably, in this embodiment, the clamping member 21 is provided with a positioning pin 211, and the mold body 1 is provided with a positioning pin hole 161. The positioning pin 211 can be inserted into the positioning pin hole 161 to limit the connection between the clamping member 21 and the mold body 1. The positioning pin 211 and the positioning pin hole 161 can ensure the positional accuracy between the clamping member 21 and the mold body 1, thereby ensuring the structural accuracy of the duct housing.

[0049] Furthermore, in this embodiment, the end of the positioning mandrel 22 away from the circumferential abutment portion 221 is provided with a frustum portion 222, and the diameter of the frustum portion 222 gradually increases along the direction approaching the other end of the positioning mandrel 22. The columnar portion 15 is provided with a tapered hole, and the inner wall of the tapered hole forms a tapered limiting surface. The tapered limiting surface can fit against the outer circumferential surface of the frustum portion 222, thereby limiting the positioning mandrel 22 and further ensuring the positional accuracy between the positioning mandrel 22 and the mold body 1.

[0050] Optionally, the columnar portion 15 and the fan-shaped portion 16 are further provided with threaded holes 162, and the positioning mandrel 22 and the clamping member 21 are respectively provided with through holes 212. The duct housing co-curing molding mold also includes a threaded connector, which can pass through the through hole 212 and be threadedly connected to the threaded hole 162, thereby fixing the positioning mandrel 22 and the clamping member 21 to the mold body 1 respectively. Exemplarily, in this embodiment, the positioning mandrel 22 is first inserted into the central cavity 111 and fixed by the threaded connector. Then, the stator blade 100 and the clamping member 21 are sequentially placed into the radial cavity 112, and the clamping member 21 is fixed by the threaded connector, thereby fixing the stator blade 100.

[0051] Preferably, when the stator blade 100 and the clamping member 21 are simultaneously placed in the radial cavity 112, the clamping member 21 and the circumferential abutment portion 221 can clamp and limit the other flange portion 1001 of the stator blade 100. It should be further noted that, in this embodiment, the stator blade 100 has two flange portions 1001, one flange portion 1001 is located at the end of the stator blade 100 close to the axis of the columnar portion 15, and the other flange portion 1001 is located at the end of the stator blade 100 away from the axis of the columnar portion 15.

[0052] like Figure 6 As shown, in this embodiment, the maximum diameter of the tapered portion is greater than the diameter of the circumferential abutment portion 221, thereby forming a stepped surface 223 on the outer periphery of the positioning mandrel 22. The stepped surface 223 can abut against the stator blade 100 in a direction close to the mounting opening 12, thereby simultaneously ejecting the positioning mandrel 22 and the formed duct housing under the action of the ejection assembly, reducing demolding difficulty and improving production efficiency.
