Technical Field

[0001] This utility model relates to the field of web plate mold technology, specifically a segmented mold that facilitates demolding. Background Technology

[0002] The web is a key structural component of wind turbine blades, mainly used to connect the PS and SS shells of the blades and transfer loads. Its molding quality has a significant impact on the overall performance of the blades and the stable operation of the wind turbine. The web is usually pre-formed separately in a web steel platform mold, and then bonded to the upper and lower shells through mold assembly.

[0003] The molds widely used in the market have obvious defects. After the web is formed, these molds often face the problem of difficult demolding. On the one hand, the demolding process requires a lot of manpower and time, which seriously slows down the production rhythm and greatly affects the production efficiency. On the other hand, the difficult demolding operation can also easily damage the formed web, destroy its structural integrity and surface quality, and thus have an extremely adverse effect on product quality. To this end, we propose a segmented mold that is easy to demold to solve the above problems. Summary of the Invention

[0011] This utility model provides a segmented mold that facilitates demolding, and has the following beneficial effects: This invention creates multiple mold cavities within the mold body and installs movable push plates within these cavities.

If the specific posture changes, the directional indicator will also change accordingly.

[0016] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0017] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

The output end of the servo motor 12 is connected to the end of the rotating connecting rod 10.

[0019] By opening multiple sets of mold cavities 2 inside the mold body 1 and installing movable push plates 4 inside the mold cavities 2, the linear driver 6 can synchronously push all the push plates 4 through the connecting bracket 7 and the push rod 5 to achieve synchronous demolding of multiple sets of mold cavities 2. Then, multiple sets of servo motors 12 drive the rotating connecting rod 10 to drive the sealing plate 11 to open and close, which facilitates the demolding operation and further realizes synchronous opening of multiple sets of mold cavities 2, improves demolding efficiency, and effectively avoids damage to the product during demolding.

[0020] In other embodiments, the push plate 4 is shaped to match the mold cavity 2, and the surface of the push plate 4 is provided with an anti-stick coating; This design ensures that the shape of the push plate 4 matches that of the mold cavity 2, guaranteeing uniform material feeding.

[0024] In other embodiments, the anti-stick coating is a polytetrafluoroethylene coating; This design gives the PTFE coating extremely low surface energy, preventing resin adhesion, further reducing demolding resistance, and extending mold life.

[0025] This utility model provides a segmented mold that facilitates demolding, and its specific working principle is as follows: Mold closing and material injection: The sealing plate 11 is closed under the drive of the servo motor 12 to form a complete cavity, and then the material is injected into the mold cavity 2 for molding.
