[0002] With the continuous development of UAV technology, the nose of the UAV is no longer a simple fairing cover that reduces airflow resistance. New technology development installs radar inside the nose and pods and other equipment outside. The installation of radar inside the nose requires the nose to have excellent wave-transmitting performance, making the overall structure of the UAV nose more uniform.

[0003] However, since the drone head has more functions and higher requirements for wind resistance, the structure of the drone head is more complicated, which increases the difficulty of demolding the product.

[0004] The existing UAV nose molding is usually composed of multiple parts spliced ​​together, which leads to splicing errors in the spliced ​​nose, resulting in a decrease in the overall smoothness of the UAV nose and cannot meet actual molding requirements.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0028] refer to Figure 1 The drone hood 60 is an L-shaped hollow shell structure, including a first structure arranged horizontally and a second structure arranged vertically and connected to the first structure, wherein a pod installation opening 50 is opened at the bottom of the first structure, and a pod placement groove matching the pod outer wall is recessed inward on the side wall of the second structure, and the pod placement groove is a hemispherical structure; the tail end of the drone hood 60 is an open structure.

[0029] Usually, when the drone hood 60 is formed, it needs to be formed separately in multiple parts and then spliced ​​together, resulting in low splicing accuracy of the drone hood 60, which cannot meet actual use requirements; if it is formed in one piece, the one-piece molding is difficult due to the undercut at the pod installation port 50.

[0030] Example 1

[0031] refer to Figures 2 to 4 The present embodiment provides an integrated molding mold for a drone hood, including an upper mold 10 and a lower mold 20 matching the upper mold 10. The upper mold 10 is provided with an upper hood cavity 11 matching the top of the drone hood 60, and the lower mold 20 is provided with an L-shaped hood lower cavity 21 matching the bottom of the drone hood 60. After the upper mold 10 and the lower mold 20 are molded together, the hood upper cavity 11 and the L-shaped hood lower cavity 21 can form the outer wall contour of the drone hood 60.

[0032] Among them, an inverted insert 22 is provided on the lower mold 20, and the inverted insert 22 is located below the upper mold 10. The inverted insert 22 is detachably connected to the lower mold 20, and the top of the inverted insert 22 extends into the L-shaped head cover lower cavity 21. The inverted insert 22 is set at a position corresponding to the pod mounting port 50. In the actual molding process, the inverted insert 22 is set so that the corresponding position of the drone head cover 60 forms a pod mounting port 50 with accurate position and size. At the same time, when demolding, it is only necessary to remove the inverted insert 22 and the upper mold 10 to remove the corresponding bottom of the drone head cover 60 from the lower mold 20. The structure is simple and the operation is convenient, so that the drone head cover 60 can be formed in one piece to ensure its accuracy.

[0033] Specifically, in order to avoid the inconvenience of demolding between the upper mold 10 and the lower mold 20, the parting surface between the upper mold 10 and the lower mold 20 is set along the outermost contour of the drone hood 60 in the horizontal direction, that is, the parting surface is set along the horizontal line where the widest position of the first structure is located, so that the formed drone hood 60 can be smoothly demolded from the space enclosed by the hood upper cavity 11 and the L-shaped hood lower cavity 21.

[0034] Among them, the upper mold 10 and the lower mold 20 are detachably connected by bolts, and the bolts are located on both sides of the upper cavity 11 of the hood and on both sides corresponding to the lower cavity 21 of the L-shaped hood, ensuring that the connection between the upper mold 10 and the lower mold 20 is stable and reliable when the drone hood 60 is formed.

[0035] Among them, the L-shaped hood lower cavity 21 includes a transverse hood lower cavity 30 and a vertical hood lower cavity 31 connected to the transverse hood lower cavity 30, wherein the transverse hood lower cavity 30 matches the bottom contour of the first structure, and the vertical hood lower cavity 31 matches the contour of the second structure, and the hood upper cavity 11 and the transverse hood lower cavity 30 are opposite to form the outer contour of the first structure, wherein the pod placement groove is located in the middle position of the vertical hood lower cavity 31, so that the upper and lower ends of the vertical hood lower cavity 31 are arranged on the outside of the pod placement groove.

[0036] Among them, the bottom end of the inverted insert 22 is connected to the outer wall of the lower mold 20, and the top end of the inverted insert 22 extends upward to the lateral head cover lower cavity 30. The inverted insert 22 and the lower mold 20 are also detachably connected, and the detachable connection can be selected by threaded connection.

[0037] The top of the inverted insert 22 can be selected to be a disc structure matching the pod mounting port 50. Since the pod mounting port 50 is close to the pod placement slot, there is interference when the bottom end of the inverted insert 22 is connected to the lower mold 20. Therefore, in order to avoid increasing the difficulty of disassembly and connection between the inverted insert 22 and the lower mold 20, a bow block 33 is selected to be set on the lower mold 20. The bow block 33 is located in the lower cavity 30 of the transverse head cover and is close to the pod placement slot, and the top of the inverted insert 22 is also a bow structure. The difference is that the curvature of the top of the inverted insert 22 is greater than the curvature of the bow block 33. The top of the inverted insert 22 and the bow block 33 together form a disc structure, and the inverted insert 22 is away from the pod placement slot, thereby making the connection between the inverted insert 22 and the lower mold 20 simpler and reducing costs.

[0038] After the inverted insert 22 is connected to the lower mold 20, the top of the inverted insert 22 is flush with the bow block 33. When removing the mold, the upper mold 10 is removed first, and then the inverted insert 22 is removed. At this time, the drone hood 60 can be moved outward relative to the lower mold 20, and the bow block 33 moves in the pod installation port 50 to disengage the pod placement groove from the vertical hood lower cavity 31, thereby facilitating the detachment of the drone hood 60 from the L-shaped hood lower cavity 21 to meet actual molding requirements.

[0039] Further explanation: the drone hood one-piece molding mold provided in this embodiment also includes an end baffle 40, which is a plate-like structure. The end baffle 40 is also used to connect the upper mold 10 and the lower mold 20. The end baffle 40 is located at the end of the upper mold 10 and the corresponding end of the lower mold 20, that is, the end baffle 40 is located at the open outer side of the rear end of the drone hood 60, which can enhance the stability and reliability of the connection between the upper mold 10 and the lower mold 20; the end baffle 40 is detachably connected to the upper mold 10 and the lower mold 20.

[0040] An operation port 41 is provided on the end baffle 40, and the operation port 41 is opposite to the opening at the rear end of the drone hood 60. At the same time, the glass fiber prepreg laid in the hood upper cavity 11 and the L-shaped hood lower cavity 21 can be inspected and repaired through the operation port 41, thereby further improving the molding quality of the drone hood 60.

[0041] Furthermore, an operation port is provided on the top of the upper mold 10 , which can also facilitate the inspection of the glass fiber prepreg laid in the deep cavity part of the drone head cover 60 .

[0042] The above is the embodiment of the present application. The above embodiments and the specific parameters in the embodiments are only for the purpose of clearly describing the verification process of the application, and are not intended to limit the scope of patent protection of the present application. The scope of patent protection of the present application is still subject to its claims, and any equivalent structural changes made by using the description and drawings of the present application should be included in the scope of protection of the present application.
