[0005] To achieve the above object, the utility model provides the following technical solution: A large wind power blade mold, including a mold main body, a sealing and shaping unit, and a cover fixing unit;

[0006] Mold main body: A mold groove is opened at the upper end, and the mold groove is one-half of the symmetric structure of the blade. The mold groove gradually becomes shallower from front to back and narrows towards the middle;

[0007] Sealing and shaping unit: Comprising mounting blocks, bearings, flip covers, sealing strips, and inner shaping blocks. A mounting block is fixedly connected to the upper left side position at the front and rear ends of the mold main body. A bearing is installed in each mounting block. A longitudinal shaft body is inserted between the front and rear bearings. The shaft body is fixedly connected to the inside of one long edge of the flip cover. A sealing strip is installed along the edge on the inner side of the flip cover. Two mounting chutes perpendicular to the end face are opened inside the flip cover. An inner shaping block is slidably connected to the inside of each of the two flip covers. Limiting blocks are arranged on both sides of the inner shaping block;

[0008] Cover fixing unit: installed on the upper right side of the front and rear ends of the mold body.

[0009] The mold groove is half of the symmetric structure of the blade, and the two parts of the produced blade are butted and joined together to form a complete blade. The mounting block is used for the installation of the bearing, and the bearing cooperates with the longitudinal shaft body to enable the flipping cover plate to flip. When the flipping cover plate covers the upper side of the mold body, the sealing strip plays a sealing effect. By extending the inner plastic shaping block to different surfaces of the flipping cover plate, the groove and convex block structures of the two joined parts of the blade can be shaped: when the inner plastic shaping block extends to the inner end face of the flipping cover plate, half of the blade with a plug-in groove can be shaped; when the inner plastic shaping block extends to the outer end face of the flipping cover plate, half of the blade with a plug can be shaped; in this way, the structure of the mold can be simplified. By producing two parts with the same blade shape and through the internal plastic shaping groove and convex block structures, it is convenient for the two parts of the blade to be joined together; the cover fixing unit is used to lock the flipping cover plate.

[0036] The working principle of a large wind turbine blade mold provided by the utility model is as follows: This mold has a reliable sealing and shaping unit 3, which can simplify the structure of the mold. By producing two parts with the same shape as the blade and docking and splicing the two parts of the produced blade, a complete blade can be formed. And through the internal shaping groove and convex block structure, it is convenient for the two parts of the blade to be spliced: The mold cavity 2 is half of the symmetrical structure of the blade, and the two parts of the produced blade are docked and spliced to form a complete blade. The mounting block 31 is used for mounting the bearing 32, and the bearing 32 cooperates with the longitudinal shaft body to enable the flipping cover plate 33 to flip. When the flipping cover plate 33 covers the upper side of the mold body 1, the sealing strip 34 plays a sealing role. By extending the inner shaping block 35 to different surfaces of the flipping cover plate 33, the groove and convex block structures of the two spliced parts of the blade can be shaped: When the inner shaping block 35 extends to the inner end face of the flipping cover plate 33, half of the blade with a plug-in groove can be shaped. When the inner shaping block 35 extends to the outer end face of the flipping cover plate 33, half of the blade with a plug can be shaped. In this way, the structure of the mold can be simplified.

The clamping block 42 is used for mounting the movable short shaft 43, and the movable short shaft 43 enables the mounting box 44 to move. The mounting box 44 is used for mounting the buckle 45. When the buckle 45 is turned up, it buckles on the outside of the fixing rod 41, thereby fixing the flipping cover plate 33. The spring 46 applies an elastic force to the mounting box 44, and the mounting box 44 pulls the buckle 45 in the opposite direction, making the clamping effect of the buckle 45 on the fixing rod 41 tighter, facilitating the subsequent shaping operation.
