[0024] The forming device 6 includes a forming block 61, a protrusion 62, and a limiting hole 63. The forming block 61 is disposed in the middle of one side of the surface of the sealing plate 51. The protrusion 62 is fixedly installed in the middle of one side of the outer surface of the forming block 61. The limiting hole 63 is opened on one side of the top of the protrusion 62.

[0025] Support blocks 9 are fixedly installed around the bottom of the workbench 1.

[0026] The protrusion 62 passes through the slot 53, causing the molding block 61 to fit against the outer surface of the sealing plate 51.

[0027] The bolt 56 is threaded into the threaded hole 55 and inserted downward into the limiting hole 63.

[0028] Both the first lifting component 4 and the second lifting component 7 adopt a hydraulic cylinder or electric telescopic rod structure.

[0029] The molding block 61 is replaceable, and the shape of the molding block 61 can be designed in different shapes.

[0030] An injection tube is installed in the middle of the top of mold box 2 for injection molding.

[0031] The working principle of the high-precision fan bracket injection mold provided by this invention is as follows: During operation, the output shaft of the first lifting component 4 moves to drive the sealing plate 51 to fit against the surface of the mold box 2, sealing the injection groove 4, and the molding block 61 is embedded in the middle of the injection groove 3. The operator injects molten liquid into the injection tank 3 through the injection tube to cool and form a support; Then the first lifting component 4 output shaft moves in the opposite direction to push the sealing plate 51 and the mold box 2, and the second lifting component 7 output shaft moves to push the demolding plate 8 to push the support formed inside the injection groove 3, so that the forming support is demolded; When it is necessary to change the shape of the forming bracket, the bolt 56 can be rotated in the opposite direction to engage the threaded hole 55 and move upward.

A first lifting member 4 drives a moving sealing plate 51 in a sealing device 5 to adhere to the surface of the mold box 2, achieving a seal in the injection groove 3. This also ensures that the molding block 61 of the molding device 6 is precisely embedded in the center of the injection groove 3, providing a stable cavity for the fan bracket molding. After injection molding, the first lifting member 4 drives the sealing plate 51 to detach from the mold box 2, and the second lifting member 7 pushes the demolding plate 8 to eject the cooled and molded bracket from the injection groove 3, completing the demolding process. The entire process is highly automated and easy to operate. It can be used when producing different... When shaping the fan bracket, the molding device 6 can be removed from the slot 53 by rotating the bolt 56 in the reverse direction to disengage it from the limiting hole 63. The molding device 6 can then be replaced with a molding device 6 having a different shaped molding block 61. The protrusion 62 of the new molding device 6 can be inserted into the slot 53, and the bolt 56 can be rotated in the forward direction to insert it into the limiting hole 63. This achieves rapid assembly and limiting, greatly improving the disassembly and flexibility of the mold. It overcomes the defect of the traditional one-piece molding mold having a single shape and can meet the molding needs of various fan brackets, effectively improving production efficiency and practical effect.

[0033] Second Embodiment Please refer to the following: Figure 4 and Figure 5 Based on the high-precision wind turbine bracket injection mold and injection method provided in the first embodiment of this application, the second embodiment of this application proposes another high-precision wind turbine bracket injection mold and injection method. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0034] Specifically, the difference in the high-precision fan bracket injection mold provided in the second embodiment of this application is that elastic devices 11 are fixedly installed on both sides of the surface of the sealing plate 51, a limiting device 12 is slidably installed inside the elastic device 11, and slots 10 are opened on both sides of the outer surface of the protrusion 63.

[0035] The elastic device 11 includes a mounting box 111, a moving groove 112, a sliding groove 113, a sliding rod 114, and an elastic element 115. The mounting box 111 is fixedly installed on one side of the surface of the sealing plate 51. The moving groove 112 is opened in the middle of one side of the outer surface of the mounting box 111. Two sliding grooves 113 are respectively opened in the middle of the upper and lower sides of the inner wall of the moving groove 112. The sliding rod 114 is fixedly installed in the middle of the sliding groove 113. The elastic element 115 is sleeved on one side of the outer surface of the sliding rod 114.

[0036] The limiting device 12 includes a limiting block 121, a slider 122, a sliding hole 123, and an extrusion inclined surface 124. The limiting block 121 is slidably installed inside the sliding groove 113. The two sliders 122 are respectively fixedly installed on the upper and lower sides of the outer surface of the limiting block 121. The sliding hole 123 is opened in the middle of one side of the outer surface of the slider 122. The extrusion inclined surface 124 is disposed on one side of the outer surface of the limiting block 121.

[0037] The elastic element 115 adopts a spring structure, and one end of the elastic element 115 is connected to the slider 122.

[0038] The slider 122 is slidably mounted on the outer surface of the slide rod 114 through the sliding hole 123.

[0039] In this embodiment, the molding block 61 is designed as a cylinder, so that the middle cavity of the injection molding in the injection groove 3 is circular, which can be adapted to fan blades of different lengths.

[0040] The working principle of the high-precision fan bracket injection mold provided by this invention is as follows: During operation, when the protrusion 62 is first inserted into the slot 53, the end of the protrusion 62 presses against the pressing slope 124 of the limiting block 121. As the protrusion 62 continues to move, it presses the limiting block 121 into the moving groove 112. The limiting block 121 drives the slider 122 to slide on the surface of the slide bar 114 and presses against the elastic member 115.

[0041] When the protrusion 62 moves to the slot 10 and connects with the limiting block 121, the elastic element 115 returns to its original position and pushes the slider 122 to reset and move, so that the limiting block 121 is embedded in the inside of the slot 10, thereby automatically limiting the molding device 6 and enabling rapid assembly.

[0042] Compared with related technologies, the high-precision fan bracket injection mold provided by the present invention has the following beneficial effects: This invention provides a high-precision fan bracket injection mold. It utilizes an elastic device 11 and a limiting device 12 on both sides of the surface of a sealing plate 51, and slots 10 on both sides of the outer surface of a protrusion 62. When the protrusion 62 of the molding device 6 is inserted into the slot 53 of the sealing plate 51, the end of the protrusion 62 presses against the pressing slope 124 of the limiting block 121 in the limiting device 12. As the protrusion 62 continues to be inserted, the limiting block 121, after being compressed, slides into the moving groove 112, simultaneously driving the sliders 122 on its upper and lower sides to move along the sliding rod 114 of the elastic device 11, compressing the elastic element 115 sleeved on the sliding rod 114. When the protrusion 62 is fully inserted... When the slot 10 on the protrusion 62 corresponds to the position of the limiting block 121, the compressed elastic element 115 releases its elastic potential energy, pushing the slider 122 to drive the limiting block 121 to slide out of the moving groove 112 until the limiting block 121 is embedded in the slot 10 of the protrusion 62, thereby forming an automated auxiliary limit for the molding device 6. The molding device 6 can be quickly positioned and fixed through the cooperation of the elastic device 11 and the limiting device 12, which improves the convenience and stability of the molding device 6 during replacement and installation, ensures the precise alignment between the molding block 61 and the injection groove 3, reduces the difficulty and error of manual operation, and makes the mold assembly process more efficient and reliable.
