The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] Figure 1 A schematic diagram of a bonding corner mold provided by an embodiment of the present utility model is shown; Figure 2 The schematic diagram of the anti-dislocation structure provided by the embodiment of the utility model is shown. Figure 1 and Figure 2 , this embodiment provides a bonding corner mold and a bonding corner anti-misalignment tooling.

[0039] Specifically, the corner bonding mold includes a blade mold flange 10 and the corner bonding anti-dislocation tooling provided in this embodiment. The edge of the blade mold flange 10 is provided with an edge boss 11. The anti-dislocation structure 100 can be fixed to the blade mold flange 10. The blade can be formed on the side of the corner bonding anti-dislocation tooling and the edge boss 11 facing away from the blade mold flange 10.

[0040] The bonding angle anti-misalignment tooling provided in this embodiment includes a plurality of anti-misalignment structures 100 spliced ​​in sequence. The anti-misalignment structure 100 includes a mold body 110, and the opposite sides of the mold body 110 are respectively a blade molding side and a fixed side, and the blade is molded on the blade molding side and the side of the edge boss 11 facing away from the blade mold flange 10. Through the mold body 110, a molding foundation can be provided for the bonding angle of the blade. The anti-misalignment structure 100 also includes an anti-misalignment back plate 120, which protrudes from the fixed side and is fixedly connected to the mold body 110, and can be pressed against the fixed side of the mold body 110 of the adjacent anti-misalignment structure 100. Through the anti-misalignment back plate 120, the problem of misalignment at the splicing seam between adjacent anti-misalignment structures 100 can be prevented, and the flatness between adjacent anti-misalignment structures 100 can be ensured, thereby avoiding the problem of insufficient blade strength and improving the molding quality at the bonding angle of the blade.

[0041] Specifically, the mold body 110 includes a body connecting portion 111, a body clamping portion 112, and a body forming portion 113, which are integrally formed in sequence. The body connecting portion 111 can press against the blade mold flange 10, the body clamping portion 112 presses against the upper end surface of the edge boss 11 of the blade mold flange 10, and the body forming portion 113, which is away from the body connecting portion 111, forms the blade forming side.

[0042] More specifically, the body connecting portion 111 and the body forming portion 113 are arranged at an angle. In this embodiment, the body connecting portion 111 and the body forming portion 113 are arranged perpendicularly. In other embodiments, the angle between the body connecting portion 111 and the body forming portion 113 can be selected according to the actual shape of the blade to be formed, and this embodiment does not limit this.

[0043] More specifically, a snap-fitting groove 114 is formed on the side of the body snap-fitting portion 112 facing away from the fixed side, and the shape of the snap-fitting groove 114 matches the convex shape of the edge boss 11. This arrangement can improve the connection reliability between the body snap-fitting portion 112 and the edge boss 11 and prevent the mold body 110 from being misaligned.

The backplate connecting portion 121 can press against the main body connecting portion 111 of the adjacent anti-dislocation structure 100, the backplate clamping portion 122 can press against the main body clamping portion 112 of the adjacent anti-dislocation structure 100, and the backplate pressing portion 123 can press against the fixed side of the main body forming portion 113 of the adjacent anti-dislocation structure 100. Through the above arrangement, the degree of fit between the anti-dislocation backplate 120 and the mold body 110 of the adjacent anti-dislocation structure 100 can be ensured.

[0045] Continue to refer to Figure 1 The bonding angle anti-dislocation tooling also includes a stopper 200. The stopper 200 is disposed on the blade mold flange 10, and the body connection portion 111 can be positioned between the stopper 200 and the edge boss 11. The stopper 200 further secures the body connection portion 111, building on the already secured connection between the body clamping portion 112 and the edge boss 11, thereby improving the reliability of the positioning of the anti-dislocation structure 100 on the blade mold flange 10.

[0046] Specifically, there are a plurality of the limiting members 200, which are spaced apart and connected to the body connection portion 111 along the extension direction of the mold body 110. Through the above arrangement, the connection reliability between the body connection portion 111 and the blade mold flange 10 can be improved.

[0047] More specifically, the plurality of limiting members 200 are evenly spaced. Through the above arrangement, when the limiting members 200 are used to fix the main body connecting portion 111, the force uniformity of the main body connecting portion 111 can be improved.

[0048] More specifically, in this embodiment, the limiting member 200 is a block-shaped structure, which can be pressed against the side edge of the main body connecting portion 111 away from the main body clamping portion 112 .

[0049] Alternatively, in another embodiment, the limiting member 200 is an inverted L-shaped structure to form a snap-in slot, and the side edges of the main body connecting portion 111 can be embedded in the snap-in slot to ensure the reliability of its connection with the limiting member 200.

[0050] Alternatively, in another embodiment, among the plurality of limiting members 200, some limiting members 200 are block-shaped structures, while others are partially inverted L-shaped structures. Furthermore, the limiting members 200 with block-shaped structures and the limiting members 200 with partially inverted L-shaped structures are alternately arranged.

[0051] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
