Description

Technical Field

[0001] The present disclosure relates to the technical field of wind turbine blades, and in particular to a mold segment, a web mold, and a method for manufacturing the web mold. Background Art

[0002] The web plate mold used to manufacture the web plate is mostly an integral structure, and the outer edge of the web plate mold changes in the same manner as the web plate shape in the length direction, that is, the web plate mold corresponds to the web plate one-to-one.

[0003] When the shape and size of the web to be manufactured, or the cross-section and size of the web changes, the web mold needs to be replaced as a whole, thereby increasing production costs. Summary of the Invention

[0004] The purpose of the present disclosure is to provide a mold segment, a web mold and a method for manufacturing the web mold, which can improve the reuse rate of the web mold and reduce production costs.

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

[0006] Selecting a target web plate mold from the constructed web plate molds, wherein the target web plate mold is a web plate mold in the constructed web plate molds whose overlap with the web plate mold required for the preformed web is greater than a preset ratio;

[0007] determining differences between the target web mold and a web mold required for the preformed web;

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

[0009] The solution provided by this disclosure can reduce production cycle time and production costs by selecting pre-assembled web molds that meet the overlap requirements and modifying them. Modifying pre-assembled web molds can also increase reuse rates, allowing some mold sections to be reused and remain in production. This eliminates the need for additional space to store idle equipment, reducing the land use costs of idle equipment.

[0010] Optionally, when the difference is that some mold segments in the target web mold are different from some mold segments in the web mold required for the preformed web, modifying the difference between the target web mold and the web mold required for the preformed web includes:

[0011] Selecting some mold segments of the web mold required for the preformed web from a mold library;

[0012] Part of the mold segments in the target web mold is replaced with part of the mold segments in the web mold required for the preformed web.

[0013] Through the above solution, the web mold is assembled from multiple mold segments. When certain modifications are made, 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 at a preset position of the target web mold, modifying the difference between the target web mold and the web mold required for the preformed web includes:

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

[0016] adding the missing at least one mold segment to a predetermined 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 preformed web, modifying the difference between the target web mold and the web mold required for the preformed web includes:

[0019] The excess mold sections of the target web mold relative to the web mold required for the preformed web are removed.

[0020] Through the above solution, independent mold segments are prefabricated, and the web mold is assembled from multiple mold segments. When making certain modifications, only corresponding mold segments need to be added or removed, which facilitates the modification operation and improves the modification efficiency.

[0021] Optionally, when the difference is a different cross-sectional shape of a forming cavity of the target web mold, modifying the difference between the target web mold and the web mold required for the preformed web includes:

[0022] The shape construction unit of each mold segment of the target web mold is modified.

[0023] Through the above solution, by making the shape construction unit and the bottom functional unit of each mold segment detachable, and / or making each component of 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, without modifying the bottom functional unit. This allows the bottom functional unit to be repeated, further reducing production costs and shortening production cycles, allowing the web mold to be put into production as quickly as possible.

[0024] Optionally, the mold library comprises a plurality of prefabricated individual mold segments. The mold library comprises mold segments in unused web molds.

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

[0026] Through the above solution, it can be ensured that the cost of transformation is lower than the cost of making a new mold, so that the construction of the web mold can be completed at a lower production cost, thereby reducing production costs.

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

[0028] Selecting a plurality of mold segments from a mold library, wherein the plurality of mold segments are used to respectively form each segment of the preformed web along the length direction;

[0030] This method discloses how to use multiple mold segments to reassemble to form a new template mold. In this way, the web mold is composed of multiple mold segments. When manufacturing the web mold, different mold segments can be selected for different webs and assembled to form the required web mold. Therefore, it is only necessary to select mold segments and assemble them, without having to re-manufacture the web mold for each web. When there is a certain degree of overlap between the two webs, for example, when the cross-sectional shapes and sizes of the two webs are exactly the same, the web molds corresponding to the two webs can use the same mold segment, or in other words, the same mold segment can be used in two sets of web molds. The mold segment can be reused, thereby increasing the reuse rate, reducing the production cycle, and lowering the production cost. At the same time, the mold segments can be reused and are always in production. No additional space is required to store idle equipment, which reduces the land cost of idle equipment.

[0031] According to another aspect of the present disclosure, a mold segment is provided, which includes 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 provided 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 provided by this disclosure provides a self-contained mold segment that can independently provide heat and extract air for the mold. This eliminates the need for additional heating and vacuum modules after the web mold is formed by joining multiple segments together, simplifying the assembly process and facilitating the assembly of the web mold.

[0033] When producing three die segments with the first shape construction module, the second shape construction module, and the third shape construction module respectively, only one design solution is required for the bottom functional unit part, simplifying the design requirements and reducing the production cost. Moreover, when the cross-sectional shape of the web changes, only the shape construction unit of the web die needs to be modified, and the bottom functional unit does not need to be modified, so the bottom functional unit can be repeated, further reducing the production cost and at the same time shortening the production cycle, enabling the web die to be put into production as soon as possible.

[0034] Optionally, the shape construction unit is the first shape construction module; the first shape construction module includes two retaining edges, the two retaining edges are spaced apart on the mounting surface, and the two retaining edges and the mounting surface jointly enclose a forming cavity.

[0035] Through the above solution, the die segment can participate in the forming production of a web that is generally in a straight shape.

[0036] Optionally, the shape construction unit is the second shape construction module; the second shape construction module includes a forming bottom plate and two retaining edges, the forming bottom plate and the two retaining edges are arranged on the mounting surface, the two retaining edges are located at both ends of the forming bottom plate, and the top of the retaining edge exceeds the top surface of the forming bottom plate, and the two retaining edges and the forming bottom plate jointly enclose a forming cavity.

[0037] Through the above solution, the die segment can participate in the forming production of a web that is generally in a U shape.

[0038] Optionally, the shape construction unit is the third shape construction module; the third shape construction module includes a forming bottom plate, two retaining edges and two inner linings, the forming bottom plate and the two retaining edges are arranged on the mounting surface, the two inner linings are located at both ends of the forming bottom plate and are abutted against the forming bottom plate, the two retaining edges are respectively located on one side of the two inner linings away from the forming bottom plate, and a preset distance is left between the retaining edge and the inner lining, and the two retaining edges, the two inner linings and the forming bottom plate jointly enclose a forming cavity.

[0039] Through the above solution, the die segment can participate in the forming production of a web that is generally in an I shape.

[0040] According to another aspect of the present disclosure, there is provided a web die for forming a web, the web die having a length direction, and the web die is segmented along the length direction to form a plurality of the aforementioned die segments, and the forming cavities surrounded by the shape construction units of the plurality of die segments are interconnected and have the same cross-sectional shape.

[0041] The technical solution provided by the present disclosure is to assemble a web mold from multiple mold segments along its length. When manufacturing the web mold, different mold segments can be selected for different webs and assembled to form the required web mold, so that only the mold segments need to be selected and assembled, and there is no need to re-manufacture the web mold for each web. When there is a certain degree of overlap between the two webs, for example, when the cross-sectional shapes and sizes of the two webs are exactly the same, the web molds corresponding to the two webs can use the same mold segment, or in other words, the same mold segment can be used in two sets of web molds, and the mold segment can be reused, thereby improving the reuse rate, reducing the production cycle, and reducing production costs. At the same time, the mold segments can be reused and are always in production state, and no additional space is required to store idle equipment, which reduces the land cost of idle equipment.

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

[0043] Through the above solution, two adjacent mold segments can be tightly fitted and fixed together through the two butt joint surfaces, thereby forming a complete product molding cavity and ensuring the molding quality of the web.

[0044] Optionally, the two butting surfaces of two adjacent mold segments are concave-convex matched; or,

[0045] Optionally, the two mating surfaces of the two mold segments are planarly matched.

[0046] Through the above solution, the matching structure can be simplified, the production and splicing operations can be facilitated, and the production cost can be reduced.

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

[0049] With this solution, the bottom functional unit of each mold segment has the same width. Adjacent mold segments can be aligned and spliced ​​based on their widths, facilitating splicing. The same width and length ensures that the bottom functional units of each mold segment are completely consistent, resulting in a high degree of standardization, facilitating mass production, and reducing production costs.

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

[0051] Through the above solution, the position of each mold segment can be clearly identified from the appearance, and when replacing the mold segment, it is convenient to find the position of the mold segment to be replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] Wind power technology is advancing rapidly, and the size and shape of blades and their webs, crucial components of wind turbines, are constantly evolving. Currently, the web molds used to manufacture these blades are mostly one-piece structures. This not only ensures that the web mold is integral along its length, but also that the fixed shape module and bottom functional module are integrally formed. Changes in the desired web shape and size, or in its cross-section and size, require complete mold replacement, resulting in high production costs.

[0073] In the related art, attempts have been made to reuse and remanufacture the existing one-piece web mold, but the modification process is complicated and the reuse rate is low. The modification cost is almost the same as the cost of making a new mold, which also results in higher production costs.

[0074] To this end, the inventors of this disclosure provide a novel web mold manufacturing solution to improve web reuse. In this solution, the web mold is assembled from multiple mold segments along its length. In other words, multiple standard, independent mold segments are constructed and assembled based on the web to be formed. This allows for different mold segments to be selected for different webs. This eliminates the need to re-manufacture web molds for each web. Standard mold segments can be reused, increasing reuse and reducing production costs.

[0075] At the same time, the present disclosure also designs the top shape construction module and the bottom functional module of each mold segment into a detachable structure. When the cross-sectional shape of the web changes, only the top shape construction module can be modified or replaced, and the bottom functional module can be used, which can also improve the reuse rate and reduce production costs.

[0076] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments.

[0077] Please also see Figures 1 to 2 As shown, the present disclosure provides a web mold for forming a web 2000. Web 2000 serves as a supporting component for a blade. Web 2000 supports the blade's inner cavity and bears the primary load during blade movement. The web mold has a lengthwise direction and is segmented along the lengthwise direction to form a plurality of mold segments 1000. In other words, the web mold is formed by assembling the plurality of mold segments 1000 along the lengthwise direction. In order to adapt to the shape of the blade cavity, the cross-sectional size of the web 1000 gradually changes along the length direction, but the cross-sectional shape of the web 1000 is the same. Therefore, the forming cavities 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 cavity formed by the shape construction unit 200 can gradually change along the length direction, or in other words, the shape construction unit 200 of multiple mold segments 1000 in the same web mold is the same one of the following first shape construction module 210, second shape construction module 220 and third shape construction module 230, thereby ensuring that the cross-sectional shape of the forming cavity formed by the web 2000 formed by the web mold is the same.

[0078] In this way, the web mold is composed of multiple mold segments 1000 assembled along its length. When manufacturing the web mold, different mold segments 1000 can be selected for different webs 2000 and assembled to form the required web mold. Therefore, it is only necessary to select and assemble the mold segments 1000, without having to re-manufacture the web mold for each web. When there is a certain degree of overlap between the two webs, for example, when the cross-sectional shapes and sizes of the two webs are exactly the same, the web molds corresponding to the two webs can use the same mold segment 1000, or in other words, the same mold segment 1000 can be used in two sets of web molds. The mold segment 1000 can be reused, thereby increasing the reuse rate, reducing the production cycle, and lowering the production cost. At the same time, the mold segments can be reused and are always in production. No additional space is required to store idle equipment, which reduces the land cost of idle equipment.

[0079] Exemplarily, the number of mold segments 1000 of each web mold should be no less than 2, 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 of each web mold can be 5-10, so as to avoid the cumbersome search for the corresponding mold segment 1000 due to the excessive number of mold segments 1000, and to avoid the excessive size of a single mold segment 1000 that is inconvenient for assembly due to the insufficient number of mold segments 1000. Among them, two adjacent mold segments 1000 can be connected by a detachable structure to facilitate subsequent disassembly operations. Of course, two adjacent mold segments 1000 can also be connected by a fixed connection method, such as welding, etc., but it should be noted that if a fixed connection method such as welding is used, care should be taken to minimize the number of welds or the amount of welding to facilitate subsequent disassembly operations.

[0080] In some embodiments, as Figures 3 to 8 As shown, along the length direction, at least one end of the mold segment 1000 is provided with a docking surface 300, and two adjacent mold segments 1000 are docked through the two docking surfaces 300. In this way, the two adjacent mold segments 1000 can be tightly fitted and fixed together through the two docking 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, the mold segments 1000 at both ends of the web mold each have a docking surface 300, and this docking 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 docking surfaces 300 at both ends of the length direction, so that every two adjacent mold segments 1000 in the web mold can fit tightly together. The docking surface 300 can 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 docking surface 300 can 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, as Figure 3 and Figure 4 As shown, the two docking surfaces 300 of two adjacent mold segments 1000 can be matched with each other, that is, the docking surface 300 of one mold segment 1000 is at least partially convex toward the docking surface 300 of the other mold segment 1000, and the docking surface 300 of the other mold segment 1000 is at least partially provided with a depression that matches the protrusion.

[0083] For example, the two butting surfaces 300 of two adjacent mold segments 1000 may be serrated and matched with each other. The two butting surfaces 300 of two adjacent mold segments 1000 may be matched with each other through a convex circle and a circular groove.

[0084] In some other embodiments, such as Figures 5 to 8 As shown, the two butting surfaces 300 of two adjacent mold segments 1000 are planarly matched, thereby simplifying the matching structure, facilitating production and splicing operations, and reducing production costs.

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

[0086] The width of the bottom functional unit 100 of each mold segment 1000 may be different. In this way, the desired mold segment 1000 can be found based on the difference in width, which facilitates the identification of different mold segments 1000.

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

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

[0089] Further, such as Figure 5As shown, the length of the bottom functional unit 100 of each mold segment 1000 is the same. In this way, the bottom functional unit 100 of each mold segment 1000 is completely consistent, 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 as having a root end and a tip end positioned opposite each other along its length. The root end is used to form the root portion of the web, and the tip end is used to form the tip portion 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 end. This allows for clear visual identification of the position of each mold segment 1000, making it easier to locate the desired mold segment 1000 when replacing it.

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

[0092] It should be pointed out that the width of the bottom functional unit 100 of multiple mold segments 1000 in the web mold decreasing from the root end to the tip end may include the situation that the width of the bottom functional unit 100 of multiple mold segments 1000 in the web mold gradually decreases from the root end to the tip end, that is, the width of each mold segment 1000 is different; it may also include the situation that the width of the bottom functional unit 100 of multiple mold segments 1000 in the web mold tends to decrease from the root end to the tip end as a whole, and the widths of some adjacent mold segments 1000 are the same.

[0093] Regarding the specific structure of the mold segment 1000, Figures 9 to 14 As shown, mold segment 1000 comprises a bottom functional unit 100 and a shape-forming unit 200. The bottom functional unit 100 comprises a support platform 110 with a mounting surface 111. A heating module and a vacuum module are housed within the support platform 110, allowing each mold segment 1000 to form an independent entity, independently providing heat and extracting air for the mold. This eliminates the need for additional heating and vacuum modules after multiple mold segments 1000 are joined together to form a web mold, simplifying the assembly process and facilitating the assembly of the web mold.

[0094] The shape construction unit 200 is detachably disposed 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 die 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 solution is required for the bottom functional unit 100 part, simplifying the design requirements and reducing the production cost.

[0095] Moreover, when the cross-sectional shape of the web 2000 changes, only the shape construction unit 200 needs to be modified for the web die, 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 die segments 1000 can form a web that is approximately 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 adapted 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 die segments 1000 can form a web that is approximately in a U-shaped.

[0099] Specifically, as Figure 11 and Figure 12 shown, the second shape construction module 包括成型底板202和两个挡边201,成型底板202和两个挡边201设于安装面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 disposed 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 end 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 adapted 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 the plurality of mold segments 1000 can form a substantially I-shaped web.

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

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

[0103] The ribs 201 may be tilted at a certain angle to the mounting surface 111 so that the formed webs adapt to the shape of the blade cavity, thereby improving the supporting effect of the webs on the blade cavity.

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

[0105] Selecting a plurality of mold segments 1000 from a mold library, wherein the plurality of mold segments 1000 are used to respectively form each segment of the preformed 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 a web mold required for the preformed web 2000 , or in other words, to form a web mold for forming the preformed web 2000 .

[0107] This method discloses how to use multiple mold segments 1000 to reassemble a new template mold. Thus, a web mold is assembled from multiple mold segments 1000. During web mold manufacturing, different mold segments 1000 can be selected for different webs 2000 and assembled to form the desired web mold. This eliminates the need to re-manufacture the web mold for each web by simply selecting and assembling the mold segments 1000. When two webs overlap to a certain degree, for example, when the cross-sectional shapes and dimensions of the two webs are identical, the web molds corresponding to the two webs can use the same mold segment 1000. Alternatively, the same mold segment 1000 can be used in two web molds. This allows for reuse of the mold segments 1000, thereby increasing reuse rates, reducing production cycles, and lowering production costs. Furthermore, the mold segments 1000 are reusable and always in production, eliminating the need for additional space to store idle equipment and reducing the cost of idle equipment.

[0108] In actual applications, the manufacturing operation of the web mold can be performed by a user according to the above method, or by a robot or a manipulator.

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

[0110] Selecting a target web plate mold from the constructed web plate molds, wherein the target web plate mold is a web plate mold in the constructed web plate molds whose overlap with the web plate mold required for the preformed web is greater than a preset ratio;

[0111] Determine the difference between the target web mold and the web mold required for the preformed web;

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

[0113] This method reduces production cycle time and production costs by selecting an already constructed web mold that meets the overlap requirements and modifying the already constructed web mold. Furthermore, modifying the already constructed web mold increases reuse, allowing some mold segments 1000 to be reused and always in production. This eliminates the need for additional space to store idle equipment, reducing the cost of idle equipment.

[0114] The preset ratio is typically calculated based on the cost of the modification and the cost of the new mold. Specifically, when the modification cost equals the cost of the new mold, the ratio of the overlap between the constructed web mold and the web mold required for the preformed web is the preset ratio. This ensures that when the overlap between the constructed web mold and the web mold required for the preformed web exceeds the preset ratio, the web mold can be constructed at a lower production cost. For example, the preset ratio may be 50%.

[0115] In actual applications, the manufacturing operation of the web mold can be performed by a user according to the above method, or by a robot or a manipulator.

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

[0117] Example 1: When the difference is that some mold segments in the target web mold are different from some mold segments in the web mold required for the preformed web, modifying the difference between the target web mold and the web mold required for the preformed web includes:

[0118] Selecting a partial mold segment of a web mold required for preforming the web from a mold library;

[0119] Part of the mold segments in the target web mold are replaced with part of the mold segments in the web mold required for the preformed web.

[0120] For example, suppose Figure 15 The web mold A in the figure is the target web mold, and the web mold A is assembled from independent mold segments A1, A2, A3, A4, A5, A6, A7 and A8. Figure 16 Web mold B is the web mold required for the preformed web. Web mold B is assembled from independent mold segments A1, A2, A3, A4, A5, A6, and A9. Web mold B can utilize mold segments A1, A2, A3, A4, A5, and A6 from web mold A. Therefore, web mold B, the web mold required for the preformed web, can be formed by simply removing mold segments A7 and A8 from web mold A and replacing them with mold segment A9.

[0121] In this embodiment, the web mold is assembled from a plurality of mold segments 1000 . In case of certain modifications, only the corresponding mold segments 1000 need to be replaced, which facilitates the modification operation and improves the modification efficiency.

[0122] In the second embodiment, when the difference is that at least one mold segment is missing from the preset position of the target web mold, modifying the difference between the target web mold and the web mold required for the preformed web includes:

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

[0124] At least one missing mold segment is added to the target web mold at a preset position.

[0125] For example, suppose Figure 15 The web mold A in the figure is the target web mold. Web mold A is assembled from independent mold segments A1, A2, A3, A4, A5, A6, A7, and A8. The web mold required for the preformed web is assembled from segments A0, A1, A2, A3, A4, A5, A6, A7, and A8. Therefore, only segment A0 needs to be selected and attached to the front of segment 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 preformed web, modifying the difference between the target web mold and the web mold required for the preformed web includes:

[0127] The excess mold sections of the target web mold relative to the web mold required for the preformed web are removed.

[0128] In this embodiment, independent mold segments 1000 are prefabricated, and the web mold is assembled from multiple mold segments 1000. When certain modifications are made, only corresponding mold segments 1000 need to be added or removed, which facilitates the modification operation and improves the modification efficiency.

[0129] Example 3: When the difference is the cross-sectional shape of the forming cavity of the target web mold, modifying the difference between the target web mold and the web mold required for the preformed web includes:

[0130] Modify the shape construction element 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 may include replacing the entire shape construction unit, and may also include modifying a portion of the structure in the shape construction unit, such as adjusting the inclination angle of the rib.

[0132] In this embodiment, by making the shape construction unit 200 and the bottom functional unit 100 of each mold segment detachable, and / or making each component of the shape construction unit 200 detachable, when the cross-sectional shape of the web 2000 changes, the web mold only needs to modify the shape construction unit 200, without modifying the bottom functional unit 100. Thus, the bottom functional unit 100 can be repeated, further reducing production costs and shortening production cycles, allowing the web mold to be put into production as quickly as possible.

[0133] The mold library may include a plurality of prefabricated individual mold segments. The mold library may also include mold segments from unused web molds.
