Traditional UAV fuselage molds mostly adopt an integral design, which has problems such as long manufacturing cycle, high cost, inconvenient disassembly, installation and maintenance. Especially when forming complex curved surfaces, traditional molds are often difficult to adjust flexibly, resulting in poor adaptability to different models of UAVs and a significant increase in the cost of repeated development. In addition, the installation and positioning of existing molds mostly rely on manual calibration, which is prone to affect the forming accuracy due to positioning errors, and lacks modular design, resulting in the need to replace the whole when a local part is damaged, causing serious waste of resources.

[0031] Notches and installation holes are respectively provided at the left and right ends of each female mold. The notches are attached to the fixing seat surfaces. Each female mold is first attached to the surface of the fixing seat 10, and then fixed by bolts through the installation holes. The fitting design of the notches and the fixing seat surfaces can accurately position the female mold, ensure the connection accuracy between the female mold and the fixing seat 10. Through bolt fixing, the firmness of the connection is further enhanced, so that the female mold can maintain a stable position during the molding process, avoiding displacement or shaking, thereby ensuring the dimensional accuracy and shape accuracy of the UAV fuselage molding.

[0032] Optionally, an installation groove 12 is provided on the surface of the bottom plate 1. The installation grooves 12 are provided in multiple groups. The multiple groups of installation grooves 12 are provided through the edge of the bottom plate 1. A connecting plate 13 is provided at the lower end of each female mold. The lower end of each female mold is first clamped in the installation groove 12 through the connecting plate 13, so as to realize the plug-in fixation of each female mold on the bottom plate 1.

And so on. The ends of the first female die 28, the second female die 29, the third female die 30, and the fourth female die 31 sequentially fit with the surface of the fixing seat, and the ends of each pair are fixedly connected by bolts, thereby realizing the fixed installation of the fuselage female die 3.

[0047] Further elaborating on the specific structure of the fixing seat and the settings of the notches and mounting holes at the left and right ends of each female die, the fitting design of each notch with different surfaces of the fixing seat can accurately position the female die. During the installation process, the operator can quickly and accurately adjust the position of the female die according to the fitting situation between the notch and the fixing seat surface, ensuring the installation accuracy of the female die.

[0048] Adjacent female dies are fixedly connected by bolts through the mounting holes, making the connection between the female dies closer and more stable. During the molding process, the female dies can jointly withstand the pressure and will not have relative displacement or deformation, ensuring that the dimensions of the molded unmanned aerial vehicle fuselage are consistent and the shape is accurate.

[0049] Through a precise connection method, it is possible to ensure that the female mold does not shift or deform during the molding process, thereby ensuring the dimensional accuracy and shape accuracy of the UAV fuselage molding, and improving the overall quality and market competitiveness of the product.

[0050] Optionally, the surface of the bottom plate 1 is provided with the installation grooves 12, and four groups of the installation grooves 12 are provided.

The lower ends of the first female mold 28, the second female mold 29, the third female mold 30, and the fourth female mold 31 are first clamped in the installation grooves 12 through the connecting plates 13, so as to realize the plug-in fixation of the first female mold 28, the second female mold 29, the third female mold 30, and the fourth female mold 31 on the bottom plate 1.

[0051] The four groups of installation grooves 12 are penetrated and opened along the four edges of the bottom plate 1, so that the fixation of the female mold on the bottom plate 1 is more uniform and stable. The distribution of the installation grooves 12 can reasonably disperse the pressure borne by the female mold, avoiding deformation of the bottom plate 1 or loosening of the female mold caused by excessive local pressure, and ensuring the stability of the overall structure of the mold.

[0052] The lower ends of each female mold are plugged and fixed by being clamped in the installation grooves 12 through the connecting plates 13. The plug-in fixation method combined with the reasonable layout of the installation grooves 12 can better withstand various forces during the molding process. During the molding process, the female mold can always maintain a stable position and will not shift or shake due to pressure changes, which is beneficial to the high-quality molding of the UAV fuselage.

[0053] The male and female molds of the present application are composed of a bottom plate 1, a fuselage male mold 2, a fuselage female mold 3, and a cover plate 4. Each component is tightly connected through various methods such as bolts and plug-ins. For example, the support of the fuselage male mold 2 is fixed on the mold base surface of the male mold base 5 through the first installation hole 6 and the first positioning hole 7. The fuselage female mold 3 is attached to the surface of the support and fixed to each other through bolts. The cover plate 4 and the bottom plate 1 are also fixed through bolts. The multi-level connection method makes the overall structure of the mold very stable, and can effectively resist various external forces and internal pressures during the molding process, avoiding problems such as loosening and deformation of the mold, thereby ensuring the dimensional accuracy and shape accuracy of the UAV fuselage molding.

[0054] By setting structures such as installation planes 8, fixed seats on some supports and notches on the female mold, precise installation and positioning of the female mold are realized. The installation plane 8 and the fixed seat are bolted and fixed through the second installation hole 9 and the second positioning hole 11. After the notch of the female mold fits with the fixed seat surface, it is bolted and fixed, which can ensure the accurate position of the female mold on the male mold, reduce the molding error caused by inaccurate positioning, and improve the quality of the UAV fuselage molding.

[0055] A connecting plate 13 is provided at the lower end of the female mold, and the connecting plate 13 is snapped into the mounting groove 12 of the base plate 1 to achieve plug-in fixation. The plug-in fixation method is simple and quick, and does not require complicated operating steps, which can greatly shorten the installation and disassembly time of the mold. At the same time, the bolt connection between the components is also convenient for disassembly and assembly, which is convenient for maintenance, replacement and transportation of the mold.

[0056] The fuselage positive mold 2 adopts a modular design, consisting of a positive mold base 5 and multiple supports. Each support can be flexibly adjusted in a fixed position on the positive mold base 5 according to the requirements of different types of UAV fuselages, so that the mold can adapt to the molding of various types of UAV fuselages, improves the versatility and utilization rate of the mold, and reduces the production cost of the enterprise.

[0057] The present application adopts a variety of high-strength connection methods such as bolt connection and plug-in connection, which can withstand greater pressure and stress, and ensure that the mold will not become loose or damaged during long-term use. For example, the T-shaped mounting groove 12 and the corresponding groove design, combined with the T-shaped bolt, make the connection between the cover plate 4 and the base plate 1 more secure, and can withstand various external forces during the molding process, thereby improving the overall rigidity and stability of the mold and extending the service life of the mold.

[0058] Precise molding positioning and stable mold structure can reduce the wear and deformation between the mold components during the molding process. The female mold and the male mold fit tightly and are fixed by a variety of connection methods, avoiding mutual wear caused by shaking or displacement of components, thereby reducing the maintenance cost and replacement frequency of the mold and improving the economic benefits of the enterprise.

[0059] The male and female mold structures of the present application are reasonably designed and easy to operate. Whether it is the installation, disassembly or lifting operation of the mold, no complicated skills and tools are required. Ordinary operators can start operating after simple training, which greatly reduces the technical requirements for operators and improves the flexibility and efficiency of production.

[0060] Fast installation and disassembly, safe lifting operations and stable mold structure have jointly shortened the production cycle of UAV fuselage molding. During the production process, mold preparation and replacement can be completed more quickly, reducing production downtime and improving production line utilization, thereby improving the company's production efficiency and product delivery capabilities.
