[0037] Embodiment 1

[0038] Please refer to Figure 1 the schematic diagram of a wing forming mold with multi-position connection shown in Figure 1 The arrow indicates the direction in

[0039] A positioning and clamping of the first mold 1 and the second mold 2 is formed through a clamping and positioning assembly.

[0040] Specifically, as shown in Figure 2 , Figure 3 and Figure 7As shown, the mold closing and positioning component includes a first positioning hole and a second positioning hole. First positioning holes are provided at the four corners of the top of the first mold 1, and second positioning holes are provided through the second mold 2 corresponding to the first positioning holes.

[0041] The mold closing and positioning component further includes a first positioning member 13 and a second positioning member 14. The first positioning member 13 is arranged in the first positioning hole, and a first positioning portion 15 is provided at the top of the first positioning member 13. Optionally, it is a conical column, and its diameter gradually decreases along the direction away from the first mold 1.

[0042] The second positioning member 14 is arranged in the second positioning hole, and a second positioning portion is provided at the bottom of the second positioning member 14 corresponding to the first positioning portion 15. Optionally, the second positioning portion is a conical groove, which is adapted to the first positioning portion 15. The first positioning portion 15 extends into the second positioning portion, so as to realize the accurate positioning and mold closing of the first mold 1 and the second mold 2.

[0043] Furthermore, the first mold 1 and the second mold 2 are also positioned and connected by a plurality of fastening bolts 16, which is convenient for mold closing and makes the mold closing firm.

[0044] The molding mechanism is arranged on the mold structure, and the molding mechanism includes a molding groove 3.

[0045] Specifically, as Figure 2 to Figure 5 shown, two molding grooves 3 are provided at the top of the first mold 1 and the bottom of the second mold 2. The two molding grooves 3 are symmetrically arranged about the axis of the mold structure. The molding grooves 3 of the first mold 1 and the second mold 2 are arranged in one-to-one correspondence. The molding groove 3 is used to provide an accommodation space, and the accommodation space can accommodate the molding material. After the first mold 1 and the second mold 2 are closed and pressurized and heat-cured, the molding material can form a wing.

[0046] The two ends of the first mold 1 and the second mold 2 are the first end and the second end respectively. The molding groove 3 is communicated with the second end, and a side movable block 7 is arranged at one end of the molding groove 3 communicating with the second end, which is used to change the size of the accommodation space.

[0047] Specifically, the side movable block 7 is an L-shaped structure, and has a mounting portion 17 and a blocking portion 12 which are fixedly connected. The blocking portion 12 is located in the molding groove 3 and is adapted to the molding groove 3. The mounting portion 17 is fixedly connected with the second end. Optionally, bolt connection is used. The bolt passes through the mounting portion 17 and is screwed into the inside of the second end. By selecting side movable blocks 7 with different lengths of the blocking portion 12, the size of the accommodation space can be changed.

[0048] The forming mechanism further includes a first positioning groove 4 which is arranged at the top of the first end of the first mold 1. The number of the first positioning grooves 4 is two, corresponding to the forming grooves 3 of the two first molds 1 respectively, and symmetrically arranged about the axis of the first mold 1. The first positioning groove 4 is communicated with the forming groove 3;

[0049] Further, the first positioning groove 4 is used for accommodating the metal part 5 connecting the wing and the fuselage. A metal part positioning hole is arranged in the first positioning groove 4. The metal part positioning member 8 penetrates through the metal part 5 and extends into the metal part positioning hole, so that the metal part 5 can be installed and positioned in the first positioning groove 4, ensuring the connection accuracy between the metal part 5 and the wing formed by the pressurized heat curing of the forming material;

[0050] Further, the bottom of the metal part positioning member 8 has a fastening part for extending into the metal part positioning hole;

[0051] Further, the height of the first positioning groove 4 is higher than that of the forming groove 3, enabling the metal part 5 to be located in the middle of the wing formed by the pressurized heat curing of the forming material. The fitting clearance between the first positioning groove 4 and the metal part 5 is 0.05 mm, ensuring the positioning accuracy.

[0052] The forming mechanism further includes a second positioning groove 6. The number of the second positioning grooves 6 is six, with three in a group corresponding to the two forming grooves 3 respectively. The two groups of second positioning grooves 6 are symmetrically arranged about the axis of the first mold 1, located on the side away from each other of the two forming grooves 3, and communicated with the forming grooves 3. The projections of the three second positioning grooves 6 in the same group coincide in the first direction;

[0053] Further, a rudder angle positioning member 9 is arranged in the second positioning groove 6. The rudder angle positioning member 9 is used for connecting with the rudder angle connecting the wing and the aileron. By connecting the rudder angle with the rudder angle positioning member 9 and then installing the rudder angle positioning member 9 into the second positioning groove 6, the rudder angle can be positioned and installed;

[0054] Further, the second positioning groove 6 is also arranged at the bottom of the second mold 2 corresponding to the second positioning groove 6 of the first mold 1. After the molds are closed, the openings of the second positioning grooves 6 of the first mold 1 and the second mold 2 face each other. The mating surface of the second positioning groove 6 and the rudder angle positioning member 9 is a guiding surface, and the projected area of the second positioning groove 6 gradually increases from the bottom of the groove to the opening of the groove, facilitating the guiding when installing the rudder angle positioning member 9, ensuring the positioning accuracy of the rudder angle, and fixing the rudder angle positioning member 9 by the up-and-down extrusion of the first mold 1 and the second mold 2 during mold closing, and facilitating mold closing and demolding.

[0055] The rudder angle positioning member 9 is provided with a tenon groove 10 (as Figure 6 ). The tenon grooves 10 of the three rudder angle positioning members 9 in the same group are jointly connected to the wing beam for installing and positioning the wing beam, ensuring the positioning accuracy of the wing beam.

[0056] Outside the forming groove 3, there is a cutting and glue - flowing groove 11 connected to it. Optionally, at a position 0.5 mm away from the forming groove 3, a cutting and glue - flowing groove 11 with an R of 2.5 is set, which is used to accommodate the extruded forming material during the curing process.

[0057] The surface roughness of the contact surfaces of all components on the mold structure is less than or equal to 0.8 μm;

[0058] The surface roughness of the contact surface between the mold structure and the formed wing is less than or equal to 0.8 μm.

[0059] Embodiment 2

[0060] A forming process uses a multi - positioning - connection wing forming mold proposed in Embodiment 1. Among them, the forming material that forms the wing after heat curing includes prepreg and foamed adhesive film, and the prepreg is a composite material;

[0061] As Figure 8 shown, this forming process includes:

[0062] A forming method uses a multi - positioning - connection wing forming mold proposed in Embodiment 1. Among them, the forming material that forms the wing after heat curing includes prepreg and foamed adhesive film, and the prepreg is a composite material;

[0063] As Figure 8 shown, this forming method includes:

[0064] S01. According to the wing to be formed, calculate the target size and target number of layers of the prepreg, as well as the target weight of the foamed adhesive film, and select the side movable block 7 according to the length of the wing to be formed and install it at one end of the forming groove 3 close to the second end;

[0065] S02. Cut the prepreg according to the target size, and weigh the foamed adhesive film with the target weight;

[0066] Specifically, obtain the size of the wing to be formed, calculate the target size, target number of layers of the prepreg required for the overall skin of the wing to be formed, and the target weight of the foamed adhesive mold, cut the prepreg according to the target size, and weigh the foamed adhesive film according to the target weight; then select a side movable block 7 with an appropriate length according to the size of the wing to be formed and install it on one end of the forming groove 3 close to the second end;

[0067] S03. Lay the cut prepreg on the forming groove 3 of the first mold 1 in sequence to the target number of layers, and reserve the prepreg for fitting the forming groove 3 of the second mold 2;

[0068] Specifically, lay the prepreg cut to the required size on the forming groove 3 of the first mold 1, and reserve the prepreg in contact with the forming groove 3 of the second mold 2. Since the leading edge of the wing is subject to relatively large air resistance during the flight of the UAV, in order to ensure the continuity of the skin fibers at the leading edge of the wing, the prepreg is not cut. Place the reserved part of the prepreg outside the forming groove 3 of the first mold 1, and then stack the prepregs layer by layer until the target number of layers is reached;

[0069] Furthermore, perform a vacuum treatment during the layup process, which can reduce the bubbles generated during the layup process, thereby improving the product quality;

[0070] S04. Install the metal part 5 connecting the wing to be formed and the fuselage in the first positioning groove 4 through the metal part positioning part 8;

[0071] Specifically, connect the metal part positioning part 8 with the metal part 5, and then install the metal part positioning part 8 into the first positioning groove 4, thereby completing the positioning and installation of the metal part 5 and ensuring the installation accuracy of the metal part 5. Since the first positioning groove 4 is higher than the forming groove 3, after forming, the metal part 5 is in the middle along the thickness direction of the wing, making the connection between the wing and the fuselage more stable and conducive to increasing the structural strength;

[0072] S06. Connect the rudder angle connecting the aileron to the wing to be formed to the rudder angle positioning part 9, and install the rudder angle positioning part 9 into the second positioning groove 6;

[0073] S07. Install the wing beam to be formed into the tenon grooves 10 of multiple rudder angle positioning parts 9 on the same side;

[0074] Specifically, three rudder angle positioning parts 9 are respectively connected to three rudder angles, and then install the rudder angle positioning parts 9 connecting the rudder angles into the second positioning groove 6, and perform guiding and positioning on the rudder angle positioning parts 9 through the guiding surface of the second positioning groove 6 to ensure the installation accuracy of the rudder angles. Then bury the wing beam into the tenon grooves 10 of the rudder angle positioning parts 9, and connect the wing beam through the tenon grooves 10 of the three rudder angle positioning parts 9 to ensure the installation accuracy of the wing beam;

[0075] S08. Place the foamed adhesive film of the target weight on the prepreg;

[0076] S09. Cover the reserved prepreg on the foamed adhesive film;

[0077] Specifically, tear off the isolation film of the foamed adhesive film with the calculated weight, and evenly place the foamed adhesive film on the forming groove 3. Then turn the reserved part of the prepreg to the top of the foamed adhesive film, so that the reserved prepreg covers the foamed adhesive film, and align the edge of the reserved part of the prepreg with the edge of the prepreg in the forming groove 3 of the first mold 1;

[0078] S10. Close the second mold 2 and the first mold 1, and cure the prepreg and the foaming adhesive film by hot pressing;

[0079] Specifically, place the second mold 2 on top of the first mold 1 so that the forming grooves 3 of the second mold 2 and the first mold 1 correspond to each other. Through the positioning of the first positioning member 13 and the second positioning member 14, the second mold 2 and the first mold 1 are accurately positioned and closed. After closing the mold, the whole device is placed in a vacuum bag for vacuuming, making the prepregs closer to each other and facilitating the removal of air bubbles. Then, apply pressure to the overall mold structure after vacuum treatment so that the forming material can be thermally cured. During this process, the foaming adhesive film will expand when heated, applying pressure to the laid prepregs from the inside. The multi-layer prepregs will be squeezed, reducing the gap between the prepregs in the layer and also removing the air bubbles between the prepregs, enhancing the overall strength of the wing and improving the overall performance of the wing;

[0080] Furthermore, the cutting and bleeding groove 11 can store gas and excess glue during the thermal curing process;

[0081] Furthermore, after thermal curing and forming, demold when the temperature drops to 30 - 50 °C.

[0082] Working principle: First, according to the required wing, calculate the size, number of layers of the prepreg needed to make the wing skin, and the weight of the foaming adhesive film, and select a suitable side movable block 7 to install on the forming grooves of the first mold 1 and the second mold 2. Lay the prepreg with the calculated size on the forming groove 3 of the first mold 1, and reserve the prepreg in contact with the second mold 2. Then, layer by layer according to the required number of layers, and perform vacuum treatment during the process. After laying the prepreg, position and install the metal part 5 into the first positioning groove 4 through the metal part positioning member 8. After connecting the rudder angle with the rudder angle positioning member 9, place the rudder angle positioning member 9 in the second positioning groove 6, and install the wing beam in the tenon groove 10 of the rudder angle positioning member 9. Then, place the weighed foaming adhesive film in the forming groove 3, and cover the reserved part of the prepreg on top of the foaming adhesive film, aligning the edges of the prepreg. After that, close the first mold 1 and the second mold 2. The first positioning part 15 extends into the second positioning part, so that the first mold 1 and the second mold 2 are accurately positioned and closed. Then, place the closed mold structure into a vacuum bag for vacuuming, and then apply pressure for thermal curing, so that the prepreg and the foaming adhesive film form a wing;

[0083] Thus, the device accurately positions and installs the metal part 5 and the rudder angle through the metal part positioning piece 8 and the rudder angle positioning piece 9. Moreover, three rudder angle positioning pieces 9 position one wing beam, ensuring the installation accuracy of the wing beam, enhancing the wing strength. At the same time, through the pressurized heat curing of the prepreg and the foamed adhesive film, the wing can be formed in one step, with strong integration. The internal and external pressurized forming can enhance the wing performance, and the forming quality is also greatly improved, increasing product reliability, reducing product weight, and reducing cumbersome working steps, effectively reducing labor costs and material costs. The prepreg and the foamed adhesive film have strong adhesion, reducing the risk of the aircraft body disintegrating during flight.
