Description

Technical Field

[0001] This utility model provides a molding die, and particularly relates to a molding die for wind power equipment parts. Background Technology

[0002] Wind turbine component forming molds are specialized tools used for shaping various metal or composite material parts in wind turbine equipment. Their core function is to process raw materials into wind turbine components that meet design dimensions and performance requirements through a pre-set cavity structure under process conditions such as pressure and temperature. These components, such as blade connectors and tower flanges, directly affect the assembly accuracy and operational stability of wind turbine equipment.

[0003] Existing molds for wind power equipment parts mostly adopt an integral or semi-fixed structure, basically consisting of an upper mold, a lower mold, and a fixed frame. The upper and lower molds are rigidly connected to the frame by welding or bolts, and the curved surfaces of the cavities are directly machined onto the upper and lower mold bodies. This structure has obvious shortcomings: First, when different specifications of parts need to be processed, the entire mold must be replaced, which is not only cumbersome and time-consuming, but also requires multiple complete sets of molds, resulting in high equipment investment costs; Second, the positioning of the upper and lower molds mainly relies on the overall rigidity of the frame, and after long-term use, positioning deviations are prone to occur due to loosening of the connection, affecting the molding accuracy of the parts; Third, there is a lack of flexible auxiliary limiting structures, and lateral displacement is prone to occur due to material flow during the molding process, further reducing the product qualification rate. This application solves the above-mentioned problems of inconvenient replacement and insufficient stability by using a detachable top mold and bottom mold design and a multi-component collaborative positioning structure. Utility Model Content

[0004] In order to solve the above problems, this application provides a molding die for wind power equipment parts, which solves the problems of cumbersome overall die replacement, high cost, easy positioning deviation, and low pass rate due to lack of flexible auxiliary limit.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a molding die for wind power equipment parts, including a top mold assembly, a base assembly and a cover assembly;

[0006] The top mold assembly is used to provide a molded upper mold structure, including a top mold base and a top mold, wherein the top mold is detachably installed at the bottom of the top mold base;

[0007] The base assembly serves as a support for the lower mold during molding and includes a base, a bottom mold, and a positioning and connecting component. The bottom mold is detachably mounted on the upper surface of the base via the positioning and connecting component.

[0008] The capping assembly is used to assist in molding and limiting, and consists of a capping base and a capping component. The capping component is detachably connected to the capping base.

[0009] Preferably, the top mold base is a long strip block, and its bottom is provided with a mounting part adapted to the top mold. The top mold and the top mold base are detachably assembled by bolt connection.

[0010] Preferably, the upper surface of the base is provided with a positioning groove, the bottom of the bottom mold is provided with a positioning block adapted to the positioning groove, and the positioning connection component is a fastening bolt that passes through the base and the bottom mold to reinforce the connection between the two.

[0011] Preferably, the cap seat and the top mold are provided with slots, and the base is provided with a corresponding clip. The initial connection is achieved by the clip being inserted into the slot, and then bolts are used for tightening to complete the detachable assembly of the cap and the cap seat.

[0012] Preferably, the curved surfaces of the top mold and the bottom mold are compatible, and the two work together to form a forming cavity for wind power equipment parts. Furthermore, both the top mold and the bottom mold can be replaced independently to adapt to the forming of parts of different specifications.

[0013] Preferably, the retaining strip is located above the bottom mold and is fixedly connected to the positioning groove, and the retaining strip is made of elastic material.

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art:

[0015] When forming wind turbine parts, the top mold in the top mold assembly is detachably installed at the bottom of the top mold base via bolt connection (using the mounting part of the bottom of the top mold base that matches the top mold). The bottom mold in the base assembly is detachably installed by means of a positioning block that matches the positioning groove on the bottom of the base, and fastening bolts that pass through the base and bottom mold. The cover component of the cover assembly is initially connected by the slots on the cover base and the top mold, and the corresponding locking strip on the base (the locking strip is made of elastic material and is located above the bottom mold and fixedly connected to the positioning groove). The assembly is completed by the locking strip being inserted into the slot and the bolts being tightened. During operation, the curved shapes of the top mold and the bottom mold are used to form a forming cavity.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figure 1 and Figure 2As shown, a molding die for wind power equipment parts includes a top mold assembly 1, a base assembly 2, and a cover assembly 3. The top mold assembly 1 provides the upper mold structure for molding and includes a top mold base and a top mold 11. The top mold 11 is detachably mounted on the bottom of the top mold base, which is a long strip block with a mounting part 5 at its bottom that matches the top mold 11. The top mold 11 and the top mold base are detachably assembled by bolt connection. The base assembly 2 serves as the support for the lower mold for molding and includes a base, a bottom mold 21, and positioning connecting parts. The bottom mold 21 is detachably mounted on the upper surface of the base via the positioning connecting parts. The upper surface of the base has a positioning groove 4. The bottom of the bottom mold 21 is provided with a positioning block that is compatible with the positioning groove 4. The positioning connection component is a fastening bolt that passes through the base and the bottom mold 21 to strengthen the connection between the two. The curved shape of the top mold 11 is compatible with that of the bottom mold 21. The two work together to form the forming cavity of the wind power equipment part. Both the top mold 11 and the bottom mold 21 can be replaced independently. The cover assembly 3 is located on the side of the top mold assembly 1 and the base assembly 2. The cover seat and the top mold 11 are provided with a slot 12. The clip 13 on the base is located above the bottom mold 21 and is fixedly connected to the positioning groove 4. After the clip 13 is inserted into the slot 12, it is tightened with bolts to realize the connection between the cover part and the cover seat. From the perspective of implementation key points and innovation, this structural combination, through the bolted connection between the top mold 11 and the top mold base, and the engagement and fastening bolt connection between the bottom mold 21 and the positioning block and positioning groove 4 of the base, enables convenient replacement of the top mold 11 and the bottom mold 21, meeting the molding requirements of parts of different specifications and reducing equipment costs. Simultaneously, the engagement of the positioning groove 4 and the positioning block, the elastic engagement of the retaining strip 13 and the retaining groove 12, and the bolt reinforcement ensure the stability of the connection between each component, preventing positional displacement during the molding process and improving the molding accuracy of the parts. In solving existing problems, the detachable structure solves the problem of cumbersome replacement of traditional molds, while the multiple positioning and fastening structures solve the problem of insufficient connection stability. The synergistic effect of these structures improves the practicality and reliability of the mold.

[0030] like Figure 1-3 As shown, the cap assembly 3 is used to assist in molding and limiting. It consists of a cap base and a cap piece. The cap piece is detachably connected to the cap base. The cap base and the top mold 11 are provided with slots 12. The base is provided with a locking strip 13 corresponding to the slots 12. The initial connection is achieved by locking the locking strip 13 into the slots 12. Then, it is tightened with bolts to complete the detachable assembly of the cap piece and the cap base. The locking strip 13 is located above the bottom mold 21 and is fixedly connected to the positioning groove 4. The locking strip 13 is made of elastic material.

[0031] In this embodiment, the detachable connection between the cap seat and the cap component facilitates the individual replacement and maintenance of the cap component. When the elastic material clip 13 is inserted into the clip groove 12, it can compensate for assembly errors through its own deformation, thereby enhancing the tightness of the connection. At the same time, its fixed connection with the positioning groove 4 ensures that the limiting reference of the cap component 3 is consistent with the positioning reference of the base component 2, further improving the overall limiting accuracy. During the molding process, it effectively constrains the lateral flow of material and avoids flash or deformation of the parts. This structural design retains the flexibility of detachment and strengthens the limiting stability through elastic engagement and reference unification, making up for the defects of rigid connection and poor adaptability of traditional mold auxiliary limiting structures.

[0032] When using this molding die for wind power equipment parts, a hydraulic press is required to provide molding pressure. The output end of the hydraulic press is connected to the top of the top mold base of the top mold assembly 1 to drive the top mold assembly 1 to move up and down. A PLC control system is also required to accurately control the pressure and stroke of the hydraulic press. At the same time, lifting equipment is required to assist in the replacement of the top mold 11 and the bottom mold 21. The top mold 11 and the bottom mold 21 can be made of Cr12MoV mold steel, the clamping strip 13 can be made of nitrile rubber, and the bolts can be made of high-strength alloy structural steel. By combining these existing devices and technologies with this device, efficient and precise molding of wind power equipment parts can be achieved.

[0033] Specifically, when installing this device, first fix the base of the base assembly 2 to the machine tool worktable with expansion bolts, then align the positioning block at the bottom of the bottom mold 21 with the positioning groove 4 on the base and insert it, insert the fastening bolt and tighten it with a torque wrench to the preset torque; then connect the top mold 11 to the top mold base with bolts through the mounting part 5, and use a level to calibrate the parallelism between the top mold 11 and the bottom mold 21; when installing the cover assembly 3, first let the elastic clip 13 be inserted into the clip groove 12 to achieve the pre-position, and then tighten the connecting bolts with a wrench. In use, the blank of the wind power part to be formed is placed on the curved surface of the bottom mold 21. The hydraulic press is started to make the top mold assembly 1 move downward. The mold closing distance between the top mold 11 and the bottom mold 21 is controlled by the limit switch. During the mold closing process, the sealing assembly 3 compensates for the assembly gap through the elastic deformation of the clamping strip 13. After the mold is closed, the preset pressure is maintained until the part is formed. After the forming is completed, the hydraulic press drives the top mold assembly 1 to move upward and reset. The bolts of the sealing assembly 3 are loosened and the formed part is taken out. When changing the top mold 11 or bottom mold 21 of different specifications, it is only necessary to loosen the corresponding connecting bolts to complete the disassembly and replacement. The pressure and displacement parameters can be monitored through the machine tool control panel throughout the process.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
