Description

Technical Field

[0001] This disclosure relates to the technical field of wind turbine blades, and particularly to a mold section and a web mold. Background Technology

[0002] Most web molds used to manufacture webs are integral structures, and the outer edge of the web mold changes in the same way as the shape of the web in the length direction. In other words, the web mold and the web correspond one-to-one.

[0003] When the shape and size of the web to be manufactured, or the cross-section and size of the web, change, the entire web mold needs to be replaced, thereby increasing production costs. Utility Model Content

[0004] The purpose of this disclosure is to provide a mold segment and a web mold that can improve the reusability of the web mold and reduce production costs.

[0005] According to one aspect of this disclosure, a method for manufacturing a web plate mold is provided, the method comprising:

[0006] Select a target web mold from the existing web molds, wherein the target web mold is a web mold whose overlap with the web mold required for the preformed web is above a preset ratio.

[0007] Determine the differences between the target web mold and the web mold required for the pre-formed web;

[0008] Modify the differences between the target web mold and the web mold required for the preformed web to form the web mold required for the preformed web.

[0009] The solution provided in this disclosure can reduce production cycle and lower production costs by selecting pre-built web plate molds that meet the overlap requirements and modifying them. Simultaneously, modifying pre-built web plate molds increases reusability, allowing some mold sections to be reused and always in production, eliminating the need for additional space to store idle equipment and reducing the land use costs associated with idle equipment.

[0010] Optionally, when the difference is that a portion of the mold segment in the target web mold is different from a portion of the mold segment in the web mold required for the preformed web, the modification of the difference between the target web mold and the web mold required for the preformed web includes:

[0011] Select a portion of the mold segments from the mold library required for the preformed web;

[0012] Replace a portion of the mold segment in the target web mold with a portion of the mold segment in the web mold required for the preformed web.

[0013] The above scheme assembles the web plate mold into multiple mold segments. When making certain modifications, only the corresponding mold segments need to be replaced, which facilitates the modification operation and improves the modification efficiency.

[0014] Optionally, when the difference is that at least one mold segment is missing from the preset position of the target web mold, the difference between modifying the target web mold and the web mold required for the pre-formed web includes:

[0015] Select at least one missing mold segment from the mold library;

[0016] Add the missing at least one mold segment to the preset position of the target web mold;

[0017] or,

[0018] When the difference is that the target web mold has at least one more mold segment than the web mold required for the pre-formed web, the differences in modifying the target web mold and the web mold required for the pre-formed web include:

[0019] Remove the excess mold segments of the target web mold relative to the web mold required for the preformed web.

[0020] The above scheme involves prefabricating independent mold segments, assembling the web plate mold from multiple mold segments. In case of modifications, only the corresponding mold segments need to be added or removed, which facilitates the modification operation and improves the modification efficiency.

[0021] Optionally, when the difference lies in the cross-sectional shape of the forming cavity of the target web mold, the difference between modifying the target web mold and the web mold required for the pre-formed web includes:

[0022] Modify the shape construction unit of each mold segment of the target web mold.

[0023] The above solution involves making the shape construction unit and bottom functional unit of each mold segment detachable, and / or making each component in the shape construction unit detachable. When the cross-sectional shape of the web changes, the web mold only needs to modify the shape construction unit, while the bottom functional unit remains unchanged. This allows for the reuse of the bottom functional unit, further reducing production costs and shortening the production cycle, enabling the web mold to be put into production as quickly as possible.

[0024] Optionally, the mold library includes multiple prefabricated individual mold segments. The mold library includes mold segments from unused web molds.

[0025] Optionally, the preset ratio is 50%.

[0026] The above solution ensures that the modification cost is lower than the cost of making a new mold, thus enabling the construction of the web plate mold to be completed at a lower production cost, thereby reducing production costs.

[0027] According to another aspect of this disclosure, a mold segment and a method for manufacturing a web mold are provided, the method comprising:

[0028] Select multiple mold segments from the mold library, the multiple mold segments being used to respectively form each segment of the pre-formed web along the length direction;

[0029] The multiple mold segments are combined and connected along the length of the pre-formed web to form the web mold required for the pre-formed web.

[0030] This method discloses how to reassemble multiple mold segments to form a completely new template mold. In this way, the web mold is composed of multiple mold segments. During web mold manufacturing, different mold segments can be selected and assembled for different webs to form the required web mold. Therefore, only mold segments need to be selected and assembled, eliminating the need to remanufacture a web mold for each web. When two webs have a certain degree of overlap, for example, when the cross-sectional shape and dimensions of parts of the two webs are completely identical, the web molds corresponding to the two webs can use the same mold segment. In other words, the same mold segment can be used in two sets of web molds, enabling mold segment reuse, thereby improving reusability, reducing production cycle time, and lowering production costs. Simultaneously, the mold segments can be reused and remain in a production state at all times, eliminating the need for additional space to store idle equipment and reducing the land use costs associated with idle equipment.

[0031] According to another aspect of this disclosure, a mold segment is provided, the mold segment including a bottom functional unit and a shape construction unit, wherein the bottom functional unit includes a support platform having a mounting surface, and a heating module and a vacuum module are provided on the support platform; the shape construction unit is detachably disposed on the mounting surface, and the shape construction unit includes any one of a first shape construction module, a second shape construction module and a third shape construction module.

[0032] The technical solution disclosed herein allows each mold segment to form an independent unit, capable of providing heat and extracting gas independently. Thus, after assembling multiple mold segments to form the web mold, there is no need for additional heating and vacuum modules, simplifying the assembly process and facilitating the assembly of the web mold.

[0033] When producing mold sections with three different shape construction modules (first, second, and third), only one design scheme is needed for the bottom functional unit, simplifying design requirements and reducing production costs. Furthermore, when the cross-sectional shape of the web changes, the web mold only needs to modify the shape construction unit; the bottom functional unit remains unchanged. This allows for the reuse of the bottom functional unit, further reducing production costs and shortening the production cycle, enabling the web mold to be put into production as quickly as possible.

[0034] Optionally, the shape construction unit is a first shape construction module; the first shape construction module includes two flanges, which are spaced apart on the mounting surface, and the two flanges and the mounting surface together form a molding cavity.

[0035] Through the above scheme, the mold section can participate in the molding production of the web plate, which is roughly in the shape of a straight line.

[0036] Optionally, the shape construction unit is a second shape construction module; the second shape construction module includes a molding base plate and two baffles, the molding base plate and the two baffles are disposed on the mounting surface, the two baffles are located at both ends of the molding base plate, and the top of the baffles extends beyond the top surface of the molding base plate, the two baffles and the molding base plate together form a molding cavity.

[0037] Through the above scheme, the mold section can participate in the molding production of the web plate, which is roughly U-shaped.

[0038] Optionally, the shape construction unit is a third shape construction module; the third shape construction module includes a molding base plate, two side guards and two inner linings, the molding base plate and the two side guards are disposed on the mounting surface, the two inner linings are located at both ends of the molding base plate and abut against the molding base plate, the two side guards are respectively located on the side of the two inner linings away from the molding base plate, and a preset distance is left between the side guards and the inner linings, the two side guards, the two inner linings and the molding base plate together surround to form a molding cavity.

[0039] Through the above scheme, the mold section can participate in the molding production of the web plate, which is roughly I-shaped.

[0040] According to another aspect of this disclosure, a web mold is provided for forming a web. The web mold has a length direction and is divided into multiple mold segments along the length direction. The forming cavities formed by the shape construction units of the multiple mold segments are interconnected and have the same cross-sectional shape.

[0041] The technical solution disclosed herein comprises a web mold assembled from multiple mold segments along its length. During web mold manufacturing, different mold segments can be selected and assembled for different webs to form the required web mold. This eliminates the need to remanufacture a web mold for each web. When two webs have a certain degree of overlap, for example, when the cross-sectional shape and dimensions of parts of the two webs are completely identical, the web molds corresponding to the two webs can use the same mold segment. In other words, the same mold segment can be used in two sets of web molds, enabling mold segment reuse, thereby improving reusability, reducing production cycle time, and lowering production costs. Simultaneously, the mold segment can be reused and remains in a production state, eliminating the need for additional space to store idle equipment and reducing the land use costs associated with idle equipment.

[0042] Optionally, along the length direction, at least one end of the mold segment is provided with a mating surface, and two adjacent mold segments are mated together through the two mating surfaces.

[0043] With the above solution, two adjacent mold sections can be tightly fitted and fixed together through these two mating surfaces, thereby forming a complete product forming cavity and ensuring the forming quality of the web.

[0044] Optionally, the two mating surfaces of two adjacent mold segments are in a concave-convex fit; or,

[0045] Optionally, the two mating surfaces of the two mold segments are connected in a planar fit.

[0046] The above solution simplifies the assembly structure, facilitates production and assembly operations, and reduces production costs.

[0047] Optionally, the width of the bottom functional units of each of the mold segments is at least partially the same.

[0048] Optionally, the bottom functional units of each mold segment have the same width; and / or, the bottom functional units of each mold segment have the same length.

[0049] With the above scheme, the width of the bottom functional units in each mold segment is the same, allowing adjacent mold segments to be aligned and spliced ​​by referring to their width, facilitating the splicing operation. The identical width and length of the bottom functional units in each mold segment ensure complete consistency, resulting in a high degree of standardization, which facilitates mass production and reduces production costs.

[0050] Optionally, the web mold has a root end and a tip that are arranged opposite to each other along the length direction; the width of the bottom functional units of the plurality of mold segments in the web mold decreases from the root end to the tip.

[0051] The above method allows for easy identification of the location of each mold segment by appearance, making it convenient to locate the mold segment to be replaced when replacing a mold segment. Attached Figure Description

[0071] 2000, web. Detailed Implementation

[0072] The development of wind power technology is progressing rapidly, and the size and shape of blades and their webs, which are important components of wind turbines, are also constantly changing. Currently, most web molds used to manufacture webs are one-piece structures. This is reflected not only in the fact that the web mold is an inseparable one-piece structure along its length, but also in the fact that the fixed shape construction module and the bottom functional module of the web mold are also inseparable one-piece structures. When the required shape and size of the web, or the cross-sectional area and size of the web, change, the entire mold needs to be replaced, resulting in high production costs.

[0073] In related technologies, attempts have been made to reuse and modify existing integrated web plate molds, but the modification process is complex, the reuse rate is low, and the modification cost is almost the same as the cost of making a new mold, which will also result in high production costs.

[0074] To address this issue, the inventors of this disclosure provide a novel web plate mold manufacturing scheme to improve the reusability of web plates. In this scheme, the web plate mold is assembled from multiple mold segments along its length; or, in other words, multiple standard and independent mold segments are constructed, and the corresponding mold segments are selected and assembled according to the web plate to be molded to form the web plate mold. This allows for the selection and assembly of different mold segments for different web plates, thus requiring only the use and assembly of standard mold segments. It eliminates the need to remanufacture a web plate mold for each web plate, enabling the reuse of standard mold segments, improving reusability, and reducing production costs.

[0075] Furthermore, this disclosure also designs the top shape construction module and bottom functional module of each mold segment as a detachable structure. When faced with changes in the cross-sectional shape of the web, only the top shape construction module can be modified or replaced, while the bottom functional module can be reused. This can also improve the reusability and reduce production costs.

[0076] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this disclosure, but not all embodiments.

[0077] Please see also Figures 1 to 2 As shown, this disclosure provides a web plate mold for forming a web plate 2000. The web plate 2000 serves as a support component for the blade, providing support within the blade's inner cavity and bearing the main load during blade movement. The web plate mold has a length direction and is segmented along this direction to form multiple mold segments 1000; or, in other words, the web plate mold is formed by assembling multiple mold segments 1000 along the length direction. To accommodate the shape of the blade's inner cavity, the cross-sectional size of the web 1000 gradually changes along its length, but the cross-sectional shape of the web 1000 is the same. Therefore, the forming chambers formed by the shape construction units 200 of multiple mold segments 1000 are interconnected and have the same cross-sectional shape. The cross-sectional size of the forming chambers formed by the shape construction units 200 can gradually change along its length. In other words, the shape construction units 200 of multiple mold segments 1000 in the same web mold are the same one of the first shape construction module 210, the second shape construction module 220, and the third shape construction module 230 described below, thereby ensuring that the cross-sectional shape of the forming chambers formed by the web 2000 formed by the web mold is the same.

[0078] In this way, the web mold is assembled from multiple mold segments 1000 along its length. During web mold manufacturing, different mold segments 1000 can be selected and assembled for different webs 2000 to form the required web mold. Therefore, only mold segments 1000 need to be selected and assembled, eliminating the need to remanufacture a web mold for each web. When two webs have a certain degree of overlap, for example, when the cross-sectional shape and dimensions of parts of the two webs are exactly the same, the web molds corresponding to the two webs can use the same mold segment 1000. In other words, the same mold segment 1000 can be used in two sets of web molds, thus achieving reuse of the mold segment 1000, thereby improving the reuse rate, reducing the production cycle, and lowering production costs. At the same time, the mold segments can be reused and are always in production, eliminating the need for additional space to store idle equipment and reducing the land use costs of idle equipment.

[0079] For example, the number of mold segments 1000 in each web mold should be no less than two, and the number of mold segments 1000 can be set according to the actual length of the web. Preferably, the number of mold segments 1000 in each web mold can be 5-10, which avoids the cumbersome process of finding the corresponding mold segment 1000 due to too many mold segments 1000, and also avoids the problem of an excessively large individual mold segment 1000 which would be inconvenient for assembly operations due to too few mold segments 1000. Adjacent mold segments 1000 can be connected by a detachable structure to facilitate subsequent disassembly operations. Of course, adjacent mold segments 1000 can also be connected by a fixed connection, such as welding. However, it should be noted that if welding or other fixed connections are used, care should be taken to minimize the number of weld points or the amount of welding to facilitate subsequent disassembly operations.

[0080] In some embodiments, such as Figures 3 to 8 As shown, along the length direction, at least one end of the mold segment 1000 is provided with a mating surface 300. Two adjacent mold segments 1000 are mated together through the two mating surfaces 300. In this way, the two adjacent mold segments 1000 can be tightly fitted and fixed together through the two mating surfaces 300, thereby forming a complete product molding cavity and ensuring the molding quality of the web 2000.

[0081] For example, in a web mold, each mold segment 1000 at both ends of the web mold has a mating surface 300, and the mating surface 300 is located at one end of the mold segment 1000 adjacent to another mold segment 1000. The remaining mold segments 1000 in the web mold each have two mating surfaces 300 located at both ends in the length direction, so that every two adjacent mold segments 1000 in the web mold can fit tightly together. The mating surface 300 may be located only on the shape construction unit 200 of each mold segment 1000 to ensure the integrity of the molding cavity. Of course, the mating surface 300 may also be located on the bottom functional unit 100 of each mold segment 1000, thereby facilitating the connection operation of two adjacent bottom functional units 100.

[0082] In some embodiments, such as Figure 3 and Figure 4 As shown, the two mating surfaces 300 of two adjacent mold segments 1000 can be in a concave-convex fit, that is, at least part of the mating surface 300 of one mold segment 1000 protrudes towards the mating surface 300 of the other mold segment 1000, and at least part of the mating surface 300 of the other mold segment 1000 is provided with a recess that matches the protrusion.

[0083] For example, the two mating surfaces 300 of two adjacent mold segments 1000 can be serrated and engaged with each other. The two mating surfaces 300 of two adjacent mold segments 1000 can be engaged by a convex circle and a circular groove.

[0084] In some other embodiments, such as Figures 5 to 8 As shown, the two mating surfaces 300 of two adjacent mold sections 1000 fit together, thereby simplifying the mating structure, facilitating production and splicing operations, and reducing production costs.

[0085] For example, the two mating surfaces 300 of two adjacent mold segments 1000 can be perpendicular to the length direction. The two mating surfaces 300 of two adjacent mold segments 1000 can also be inclined toward either end of the length direction.

[0086] The width of the bottom functional unit 100 of each mold segment 1000 can be different. In this way, the required mold segment 1000 can be found according to the different widths, which makes it easy to identify different mold segments 1000.

[0087] Of course, the width of the bottom functional unit 100 of each mold segment 1000 can also be at least partially the same.

[0088] For example, the bottom functional unit 100 of each mold segment 1000 has the same width, so that two adjacent mold segments 1000 can be aligned and spliced ​​with reference to their width, which facilitates the splicing operation.

[0089] Furthermore, such as Figure 5As shown, the bottom functional unit 100 of each mold segment 1000 has the same length. In this way, the bottom functional unit 100 of each mold segment 1000 is completely identical, with a high degree of standardization, which can facilitate mass production and reduce production costs.

[0090] In some other embodiments, such as Figure 8 As shown, the web mold is defined to have a root end and a tip arranged opposite each other along its length, wherein the root end is used to form the root of the web, and the tip is used to form the tip of the web. The width of the bottom functional unit 100 of the multiple mold segments 1000 in the web mold decreases from the root end to the tip. In this way, the position of each mold segment 1000 can be clearly identified visually, and the position of the mold segment 1000 to be replaced can be easily located when replacing a mold segment 1000.

[0091] For example, one side of multiple mold segments 1000 in the web mold can be flush with each other to facilitate splicing and alignment operations and improve the overall aesthetics of the web mold.

[0092] It should be noted that the width of the bottom functional unit 100 of the multiple mold segments 1000 in the web mold decreasing from the root end to the tip can include the case where the width of the bottom functional unit 100 of the multiple mold segments 1000 in the web mold gradually decreases from the root end to the tip, that is, the width of each mold segment 1000 is different; it can also include the case where the width of the bottom functional unit 100 of the multiple mold segments 1000 in the web mold generally decreases from the root end to the tip, and the width of some adjacent mold segments 1000 is the same.

[0093] Regarding the specific structure of mold section 1000, as follows: Figures 9 to 14 As shown, the mold segment 1000 includes a bottom functional unit 100 and a shape construction unit 200. The bottom functional unit 100 includes a support platform 110 with a mounting surface 111. The support platform 110 is equipped with a heating module and a vacuum module, so that each mold segment 1000 forms an independent whole, which can provide heat and extract gas for the mold independently. In this way, after multiple mold segments 1000 are spliced ​​together to form a web mold, there is no need to set up additional heating modules and vacuum modules, simplifying the splicing process and facilitating the splicing operation of the web mold.

[0094] The shape construction unit 200 is detachably provided on the installation surface 111, and the shape construction unit 200 includes any one of the first shape construction module 210, the second shape construction module 220, and the third shape construction module 230. That is to say, the bottom functional unit 100 can be adapted to the first shape construction module 210, the second shape construction module 220, and the third shape construction module 230 at the same time. In this way, when producing three mold segments 100 with the first shape construction module 210, the second shape construction module 220, and the third shape construction module 230 respectively, only one design scheme is required for the bottom functional unit 100 part, which simplifies the design requirements and reduces the production cost.

[0095] Moreover, when the cross-sectional shape of the web 2000 changes, only the shape construction unit 200 of the web die needs to be modified, and the bottom functional unit 100 does not need to be modified. Thus, the bottom functional unit 100 can be reused, further reducing the production cost and shortening the production cycle, enabling the web die to be put into production as soon as possible.

[0096] When the shape construction unit 200 is the first shape construction module 210, the web die formed by multiple mold segments 1000 can form a web that is roughly in a straight line shape.

[0097] Specifically, as Figure 9 and Figure 10 shown, the first shape construction module 210 may include two retaining edges 201. The two retaining edges 201 are spaced apart on the installation surface 111, and the two retaining edges 201 and the installation surface 111 jointly enclose a forming chamber. Among them, the retaining edge 201 can be removed from the installation surface 111 so that the bottom functional unit 100 can be applicable to other shape construction modules after removal.

[0098] When the shape construction unit 200 is the second shape construction module 220, the web die formed by multiple mold segments 1000 can form a web that is roughly in a C-shaped.

[0099] Specifically, as Figure 11 and Figure 12 shown, the second shape construction module 220 includes a forming bottom plate 202 and two retaining edges 201. The forming bottom plate 202 and the two retaining edges 201 are provided on the installation surface 111. The two retaining edges 201 are located at both ends of the forming bottom plate 202 and abut against both ends of the forming bottom plate 202, and the top of the retaining edge 201 exceeds the top surface of the forming bottom plate 202. The two retaining edges 201 and the forming bottom plate 202 jointly enclose a forming chamber. Among them, the retaining edge 201 and the forming bottom plate 202 can be removed from the installation surface 111 so that the bottom functional unit 100 can be applicable to other shape construction modules after removal.

[0100] When the shape construction unit 200 is the third shape construction module 230, the web mold formed by multiple mold segments 1000 can be formed into an approximately I-shaped web.

[0101] Specifically, such as Figure 13 and Figure 14 As shown, the second shape construction module 220 includes a molding base plate 202, two flanges 201, and two inner liners 203. The molding base plate 202 and the two flanges 201 are disposed on the mounting surface 111. The two inner liners 203 are located at both ends of the molding base plate 202 and abut against it. The two flanges 201 are respectively located on the side of the two inner liners 203 away from the molding base plate 202, and a preset distance is left between the flanges 201 and the inner liners 203 to facilitate the formation of one side flange of the web. The two flanges 201 and the molding base plate 202 together form a molding chamber. The flanges 201, the molding base plate 202, and the inner liners 203 can be removed from the mounting surface 111 so that the bottom functional unit 100 can be adapted to other shape construction modules after removal.

[0102] For example, the inner liner 203 can be made of a component with a certain degree of elasticity. When the fiberglass cloth is laid between the inner liner 203 and the side guard 202, the elastic deformation of the inner liner 203 can be used to facilitate the laying operation of the fiberglass cloth. For example, the inner liner 203 can be made of silicone or rubber.

[0103] The aforementioned flange 201 can be inclined at a certain angle to the mounting surface 111 so that the formed web adapts to the shape of the blade cavity and improves the support effect of the web on the blade cavity.

[0104] According to another aspect of this disclosure, a method for manufacturing a web plate mold is also provided, the method comprising:

[0105] Select multiple mold segments 1000 from the mold library, the multiple mold segments 1000 being used to respectively form each segment of the pre-formed web 2000 along the length direction;

[0106] The plurality of mold segments 1000 are combined and connected along the length direction of the preformed web 2000 to form the web mold required for the preformed web 2000, or in other words, to form the web mold for forming the preformed web 2000.

[0107] This method discloses how to reassemble multiple mold segments 1000 to form a completely new template mold. In this way, the web plate mold is composed of multiple mold segments 1000. During web plate mold manufacturing, different mold segments 1000 can be selected and assembled for different web plates 2000 to form the required web plate mold. Therefore, only mold segments 1000 need to be selected and assembled, eliminating the need to remanufacture a web plate mold for each web plate. When two web plates have a certain degree of overlap, for example, when the cross-sectional shape and dimensions of parts of the two web plates are completely identical, the web plate molds corresponding to the two web plates can use the same mold segment 1000. In other words, the same mold segment 1000 can be used in two sets of web plate molds, thus achieving reuse of the mold segment 1000, thereby improving the reuse rate, reducing the production cycle, and lowering production costs. At the same time, the mold segment 1000 can be reused and is always in a production state, eliminating the need for additional space to store idle equipment and reducing the land use costs of idle equipment.

[0108] In practical applications, the manufacturing operation of the web plate mold can be performed by the user according to the above method, or it can be performed by a robot or robotic arm.

[0109] According to another aspect of this disclosure, a method for manufacturing a web plate mold is also provided, the method comprising:

[0110] Select a target web mold from the existing web molds. The target web mold is a web mold whose overlap with the web mold required for the preformed web is above a preset ratio.

[0111] Determine the differences between the target web mold and the web mold required for the pre-formed web;

[0112] Modify the differences between the target web mold and the web mold required for the preformed web to form the web mold required for the preformed web.

[0113] This method selects pre-built web plate molds that meet the overlap requirements and modifies them to reduce production cycle and lower production costs. Simultaneously, modifying the pre-built web plate molds increases reusability, allowing some mold sections 1000 to be reused and always in production, eliminating the need for additional space to store idle equipment and reducing the land use costs associated with idle equipment.

[0114] The aforementioned preset ratio is typically calculated based on the modification costs and the cost of manufacturing a new mold. Specifically, when the modification costs equal the cost of manufacturing a new mold, the preset ratio is the ratio of the overlap between the existing web mold and the web mold required for the pre-formed web. This ensures that when the overlap between the existing web mold and the web mold required for the pre-formed web is above the preset ratio, the web mold can be constructed at a lower production cost. For example, the preset ratio could be 50%.

[0115] In practical applications, the manufacturing operation of the web plate mold can be performed by the user according to the above method, or it can be performed by a robot or robotic arm.

[0116] Regarding the specific differences between the target web mold and the web mold required for the preformed web, three embodiments are given below for reference.

[0117] Example 1: When the difference lies in the fact that some mold segments in the target web mold are different from some mold segments in the web mold required for the pre-formed web, the differences between the target web mold and the web mold required for the pre-formed web are modified as follows:

[0118] Select a portion of the mold segments from the web molds required for the pre-formed web from the mold library;

[0119] Replace a portion of the mold segment in the target web mold with a portion of the mold segment in the web mold required for the preformed web.

[0120] For example, assuming Figure 15 In the figure, web plate mold A is the target web plate mold, which is formed by assembling independent mold segments A1, A2, A3, A4, A5, A6, A7 and A8. Figure 16 Web plate mold B is the web plate mold required for preforming the web plate. Web plate mold B needs to be assembled from independent mold segments A1, A2, A3, A4, A5, A6, and A9. It can be seen that web plate mold B can utilize mold segments A1, A2, A3, A4, A5, and A6 from web plate mold A. Therefore, it is only necessary to remove mold segments A7 and A8 from web plate mold A and replace them with mold segment A9 to form web plate mold B, which is the web plate mold required for preforming the web plate.

[0121] In this embodiment, the web plate mold is assembled from multiple mold segments 1000. In certain modifications, only the corresponding mold segment 1000 needs to be replaced, which facilitates the modification operation and improves the modification efficiency.

[0122] Example 2: When the difference lies in the fact that at least one mold segment is missing from the preset position of the target web mold, the differences between the target web mold and the web mold required for the pre-formed web include:

[0123] Select at least one missing mold segment from the mold library;

[0124] Add at least one missing mold segment to the preset position of the target web mold.

[0125] For example, assuming Figure 15 In the diagram, web mold A is the target web mold, which is assembled from independent mold segments A1, A2, A3, A4, A5, A6, A7, and A8. The web molds required for the pre-formed web include A0, A1, A2, A3, A4, A5, A6, A7, and A8. Therefore, only mold segment A0 needs to be selected and attached to the front end of A1.

[0126] Accordingly, when the difference is that the target web mold has at least one more mold segment than the web mold required for the pre-formed web, the difference between modifying the target web mold and the web mold required for the pre-formed web includes:

[0127] Remove the excess mold segments of the target web mold relative to the web mold required for the preformed web.

[0128] In this embodiment, a prefabricated independent mold segment 1000 is used to assemble the web plate mold from multiple mold segments 1000. In case of certain modifications, only the corresponding mold segment 1000 needs to be added or removed, which facilitates the modification operation and improves the modification efficiency.

[0129] Example 3: When the difference lies in the cross-sectional shape of the forming cavity of the target web mold, the differences between the target web mold and the web mold required for the pre-formed web include:

[0130] Modify the shape construction unit of each mold segment of the target web mold.

[0131] It should be noted that modifying the shape construction unit of each mold segment of the target web mold can include replacing the entire shape construction unit, or it can include modifying part of the structure in the shape construction unit, such as adjusting the inclination angle of the flange.

[0132] In this embodiment, by making the shape construction unit 200 and the bottom functional unit 100 of each mold segment into a detachable design, and / or by making each component in the shape construction unit 200 into a detachable design, when the cross-sectional shape of the web 2000 changes, the web mold only needs to modify the shape construction unit 200, and the bottom functional unit 100 does not need to be modified. This allows the bottom functional unit 100 to be repeated, further reducing production costs and shortening the production cycle, so that the web mold can be put into production as soon as possible.

[0133] The aforementioned mold library may include multiple prefabricated individual mold segments. The mold library may also include mold segments from unused web molds.
