Technical Field

[0001] This utility model relates to the field of wind power component production technology, specifically to a mold closing auxiliary device for wind turbine blade production molds. Background Technology

[0002] With the continuous growth of global demand for clean energy, wind power generation, as an important renewable energy technology, has developed rapidly. As a key component of wind turbines, the production quality and efficiency of wind turbine blades directly affect the performance and cost of wind power generation. In the production process of wind turbine blades, mold closing is a crucial step, directly determining the forming accuracy and quality of the blades. Traditional mold closing techniques struggle to achieve precise alignment and stable control, and also suffer from problems such as high frictional resistance and slow closing speed. Because the moving mold needs to overcome significant frictional forces during movement, the mold closing process is time-consuming, reducing production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a mold-closing auxiliary device for wind turbine blade production molds, so as to solve the problems of low mold-closing accuracy and slow mold-closing speed of existing wind turbine blades mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0029] A mold-closing auxiliary device for wind turbine blade production molds, such as Figures 1-3As shown, the device includes a fixed mold 10 and a movable mold 20 for producing wind turbine blades, and a workbench 40 for placing the fixed mold 10 and the movable mold 20. A fixed base 30 is installed on the side of the movable mold 20 away from the fixed mold 10. Both the fixed mold 10 and the movable mold 20 have wind turbine blade mold grooves 11. The top and bottom of the side of the fixed mold 10 near the wind turbine blade mold groove 11 have several evenly spaced guide holes 12. The top and bottom of the side of the movable mold 20 near the wind turbine blade mold groove 11 have mold-closing auxiliary guide rods 21, which are the same number and position as the guide holes 12 and are inserted into each other. Several evenly spaced mold-closing auxiliary ball bearings 22 are installed on the bottom surface of the movable mold 20. Several... The hydraulic cylinder 31, which operates synchronously with the main unit, has a piston rod 32 connected to the back of the movable mold 20. The fixed mold 10 and the wind turbine blade mold groove 11 on the movable mold 20 are used to form the shape of the wind turbine blade. The guide hole 12 on the fixed mold 10 is inserted and engaged with the mold closing auxiliary guide rod 21 on the movable mold 20 to ensure precise alignment during mold closing. The mold closing auxiliary ball 22 on the bottom surface of the movable mold 20 can reduce the friction of the movable mold 20 during the mold closing process, making it easy to move. The hydraulic cylinder 31 and its piston rod 32 on the fixed base 30 can provide stable power to push the movable mold 20 to close with the fixed mold 10, thereby making the mold closing process of the wind turbine blade production mold more precise, smooth and efficient.

[0030] It is worth noting that the length of the mold closing auxiliary guide rod 21 is greater than the width of the fixed mold 10, ensuring that the movable mold 20 has sufficient guiding distance during the mold closing process, thereby improving the stability and accuracy of the mold closing. The mold closing auxiliary guide rods 21 at the top and bottom of the movable mold 20 are staggered. The staggered mold closing auxiliary guide rods 21 enhance the structural stability of the movable mold 20 during the mold closing process and prevent deformation or misalignment caused by uneven force.

[0031] Furthermore, a connecting seat 33 is coaxially provided at one end of the piston rod 32 that is connected to the movable mold 20. The connecting seat 33 is connected to the back of the movable mold 20 by at least two sets of fixing bolts 34. Through the connecting seat 33 and fixing bolts 34, a stable connection between the piston rod 32 and the movable mold 20 is achieved, ensuring that the connection will not loosen or fall off when the mold closing hydraulic cylinder 31 drives the movable mold 20 to move, thereby improving the reliability and safety of the entire mold closing device.

[0032] It is worth noting that the maximum stroke of the mold closing hydraulic cylinder 31 is greater than the length of the mold closing auxiliary guide rod 21, ensuring that the movable mold 20 can completely cover the fixed mold 10 during the mold closing process, thus achieving complete mold closing; at the same time, it also provides sufficient stroke space for fine-tuning during the mold closing process, improving the flexibility and adaptability of mold closing.

[0033] In addition, the top surface of the workbench 40 is equipped with a limiting strip 41 for limiting the fixed mold 10, which accurately positions and limits the fixed mold 10 on the workbench 40, preventing the fixed mold 10 from moving or shifting during the mold closing process, and ensuring the accuracy and stability of the mold closing.

[0034] The working principle of the mold closing auxiliary device for this wind turbine blade production mold:

[0035] First, the fixed mold 10 is placed on the workbench 40, and the fixed mold 10 is limited by the limiting strip 41 on the top surface of the workbench 40 to ensure its accurate position. Then, the movable mold 20 is placed on the fixed base 30, and the mold closing auxiliary guide rod 21 on the movable mold 20 is aligned with the guide hole 12 on the fixed mold 10. Since the length of the mold closing auxiliary guide rod 21 is greater than the width of the fixed mold 10 and they are staggered, they can accurately guide the movable mold 20 to dock with the fixed mold 10.

[0036] Next, the mold-closing hydraulic cylinder 31 on the fixed base 30 is activated. The piston rod 32 of the mold-closing hydraulic cylinder 31 is connected to the movable mold 20 through the connecting seat 33 and the fixing bolt 34, and begins to push the movable mold 20 to move towards the fixed mold 10. During the movement, the mold-closing auxiliary ball 22 on the bottom surface of the movable mold 20 reduces the friction of the movement, so that the movable mold 20 can smoothly approach the fixed mold 10.

[0037] Driven by the hydraulic cylinder 31, the mold closing auxiliary guide rod 21 on the movable mold 20 is gradually inserted into the guide hole 12 of the fixed mold 10 until the wind turbine blade mold groove 11 of the two molds are completely closed, thus completing the mold forming operation of the wind turbine blade.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
