Description

Technical Field

[0001] This application generally relates to the field of control panel molding technology, and specifically to a molding die for a multi-position positioning and connecting control panel. Background Technology

[0002] Currently, in the fields of aerospace and rail transportation, the industry-recognized technologies for manufacturing control panels with complex cross-reinforcing ribs and multi-position metal connectors are mainly divided into two categories: direct metal processing and composite material split molding.

[0003] While the metal solution boasts high structural strength, it suffers from inherent drawbacks such as heavy weight, significant material waste, and insufficient reliability of pre-embedded metal connectors. The composite material solution, on the other hand, requires the first molding of the composite material body parts, followed by machining of the composite material hollow mesh structure using machine tools, and then connecting multiple metal connectors via rivets or adhesives. Although this achieves weight reduction, both adhesive and riveting assembly methods can disrupt fiber continuity or introduce fragile interfaces, leading to a decrease in the overall structural strength and connection reliability of the product. Furthermore, the multiple sets of molds and lengthy process flow result in high production costs and low efficiency. Utility Model Content

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example 1 Please refer to Figures 1-7 This application provides a molding die for a multi-position positioning and connecting control panel, comprising: Molded base 1; A side panel assembly is provided circumferentially around the molding base 1, and the side panel assembly is detachably connected to the molding base 1. The first positioning module 6 is provided in multiple ways. Multiple first positioning modules 6 are spaced apart on the top of the forming base 1 and are detachably connected to the forming base 1. The first positioning module 6 is used to position the metal embedded part 11. Multiple cross-arranged rib grooves are formed between two adjacent first positioning modules 6 and between the first positioning module 6 and the side wall assembly. The rib grooves are used to form cross reinforcing ribs. The second positioning module 7 is detachably connected to the side panel assembly and is used to position the control panel connector 12. The third positioning module is located on the top of the side panel assembly and is detachably connected to the side panel assembly. The third positioning module is used to position the cover plate connector 13.

[0020] Specifically, such as Figures 1-2 As shown, the molding base 1 serves as the basic platform and assembly reference for the entire system. Its top surface is machined with high precision, with a roughness of no more than 0.8μm, to ensure the molding quality of the back of the product. The molding base 1 not only provides an installation base for other modules, but also directly constitutes the molding surface of the skin area of ​​the main body of the product. The top surface of the molding base 1 is provided with multiple positioning holes for installing the side panel components and the first positioning module 6.

[0021] Specifically, the side panel assembly is arranged circumferentially around and perpendicular to the molding base 1; the side panel assembly also adopts a modular design, and the initial precise positioning is achieved by inserting the positioning pin into the positioning hole on the molding base 1, and then the mechanical connection and locking between the side panel assembly and the molding base 1 is completed by fasteners such as screws.

[0022] Specifically, the first positioning module 6 is one of the core components for realizing the integrated molding of the mesh reinforcement ribs. Multiple first positioning modules 6 are provided, and each first positioning module 6 is provided with a first positioning pin hole. In this embodiment, after the first positioning pin hole is aligned with the corresponding positioning hole on the molding base 1, the first positioning module 6 is detachably connected to the molding base 1 by screws. The outer wall of the first positioning module 6 is used to fit the metal embedded part 11, which is specifically the frame metal embedded part 11 in this embodiment. At the same time, the gaps between two adjacent first positioning modules 6 and between the first positioning module 6 and the side wall assembly together form a cross-distributed groove space, i.e., rib groove. This structure provides a precise geometric boundary and molding space for subsequent laying of continuous fibers and compaction with silicone rubber expansion tooling to "build in situ" cross reinforcement ribs.

[0023] Specifically, the second positioning module 7 is detachably connected to the side panel assembly and is specifically used for the precise positioning and fixing of the control panel connector 12; the third positioning module is installed on the top of the side panel assembly and is used for the positioning and fixing of the cover plate connector 13; through this design, all metal connectors with different functions can be precisely pre-embedded in the main structure layering stage, realizing "multi-position positioning connection".

[0024] Specifically, this molding die, through the coordinated operation of the aforementioned components, constitutes a complete integrated molding system. This system decomposes the traditional integral female mold into multiple functionally distinct and mutually cooperating modules. This structure not only solves the technical challenge of difficult demolding of complex ribs, but also enables the precise positioning and co-curing of composite material skins, cross-reinforcing ribs, and various metal embedded parts 11 within a single mold system. This fundamentally eliminates the inherent defects such as fiber breakage and interface fragility caused by split molding and secondary assembly processes, ultimately achieving a balance between lightweight, high strength, high reliability, and high manufacturing efficiency.

[0025] In this embodiment, as Figure 7 As shown, the metal embedded part 11 is provided with an anti-detachment part, which is an inverted T-shaped structure. This effectively prevents the metal embedded part 11 from falling off or shifting in position during the molding process, thereby ensuring that each metal component maintains accurate positioning in the prepreg layering, hot pressing and curing and other process steps, and ultimately ensuring the assembly accuracy of the control panel and the reliability of the overall structure.

[0026] Working Principle: This application utilizes the cooperation of the molding base 1, side panel components, and multiple first positioning modules 6 to form intersecting rib grooves, providing a structural foundation for the integrated molding of complex intersecting reinforcing ribs. This fundamentally avoids the fiber continuity disruption caused by secondary processing and assembly in traditional composite material split molding processes, significantly improving the overall structural strength and connection reliability of the product. Simultaneously, through the coordinated layout of the first positioning module 6, the second positioning module 7, and the third positioning module, precise positioning and integrated fixing of the metal embedded part 11, the control panel connector 12, and the cover plate connector 13 at multiple locations are achieved, completely eliminating subsequent adhesive or riveting assembly steps. This greatly simplifies the process flow, reduces reliance on multiple molds, effectively lowers production costs, and improves manufacturing efficiency. This integrated mold structure successfully overcomes the inherent defects of metal solutions (large weight and significant material waste) and composite material solutions (poor interface reliability and cumbersome processes), achieving a balance between lightweight and high reliability while ensuring product molding accuracy and structural performance.

[0027] In some embodiments, the side panel assembly includes: a left side panel mold 2 and a right side panel mold 3 arranged opposite to each other, and an armrest side pressing mold 5 and a rear side panel mold 4 arranged opposite to each other; wherein: the left side panel mold 2 and the right side panel mold 3 are used to form the left side and right side of the control panel, respectively; the rear side panel mold 4 is used to form the rear side of the control panel; and the armrest side pressing mold 5 is used to apply lateral pressure to the armrest portion of the control panel.

[0028] Specifically, the roughness of the contact surfaces between the left side panel mold 2, the right side panel mold 3, the rear side panel mold 4, and the handrail side pressure mold 5 and the molded product is no greater than 0.8μm, in order to ensure the molding quality of the product.

[0029] Specifically, the left side panel mold 2 and the right side panel mold 3 are symmetrically structured and are vertically installed on the left and right sides of the molding base 1 respectively via positioning pins and fasteners, so as to achieve a detachable connection between the left side panel mold 2 and the right side panel mold 3 and the molding base 1. The left side panel mold 2 and the right side panel mold 3 are used to precisely mold the left and right sides of the control panel, respectively. The rear side panel mold 4 is installed on the rear side of the molding base 1, and the rear side panel mold 4 is detachably connected to the molding base 1 via bolts. The rear side panel mold 4 is used to form the rear side contour of the control panel.

[0030] Specifically, the armrest side pressure mold 5 is used to form the armrest part on the control panel. After the armrest side pressure mold 5 is positioned with the forming base 1 and adjacent side plates by positioning pins, it is fastened with bolts. During the forming process of the control panel, when the prepreg softens due to heat, the bolts connecting the armrest side pressure mold 5 can be tightened again, thereby applying a controllable lateral pressure force to the armrest part of the product. This active pressure mechanism can effectively compensate for material shrinkage and eliminate fit gaps, ensuring the dimensional accuracy and structural compactness of the armrest part cavity when it is finally cured, and solving the technical problems of easy deformation and difficult precision control of complex curved parts.

[0031] Specifically, the left side panel mold 2, right side panel mold 3, armrest side pressure mold 5, and rear side panel mold 4 are all initially positioned with the molding base 1 by positioning pins, and then finally fastened with bolts, together forming a rigid molding cavity. This modular side panel component design not only greatly reduces the mold processing difficulty of products with complex three-dimensional contours, but also facilitates demolding and subsequent maintenance, which is the core guarantee for realizing integrated molding and high-precision manufacturing of products.

[0032] In some embodiments, the bottom of the rear panel mold 4 is provided with a plurality of first grooves arranged along its length, and an installation space is formed between the first grooves and the molding base 1. The installation space is used to install the second positioning module 7.

[0033] Specifically, in this embodiment, three first grooves are arranged along the length of the bottom of the rear side panel mold 4. When the rear side panel mold 4 is installed on the molding base 1 by bolts, an installation space is formed between each first groove and the top surface of the molding base 1, which is dedicated to installing the second positioning module 7. In this embodiment, the second positioning template and the rear side panel mold 4 are detachably connected by bolts to form a stable mechanical fixation.

[0034] Specifically, during the control panel molding process, when the process reaches the point where the control panel connector 12 needs to be installed, the operator accurately inserts the second positioning module 7 with the control panel connector 12 into the aforementioned installation space, and secures the second positioning template to the rear side plate mold 4 with bolts, and then continues with subsequent lay-up or curing steps. The installation space provides a reliable positioning reference and rigid support for the second positioning module 7, which not only effectively avoids the structural interference problems that are prone to occur with external installation, but also significantly enhances the rigidity of the connection part, enabling the second positioning module 7 to reliably resist various process stresses during lay-up and curing, thereby ensuring that the control panel connector 12 it is fixed to is always in the precise design position.

[0035] In some embodiments, the second positioning module 7 includes: a first positioning part 71 and a first limiting part 72, wherein the first positioning part 71 and the first limiting part 72 are arranged perpendicularly; the first positioning part 71 is disposed in the installation space and is used to position the control panel connector 12; the first limiting part 72 is used to connect with the rear side plate mold 4.

[0036] Specifically, such as Figure 3 As shown, the second positioning template consists of a first positioning part 71 and a first limiting part 72 arranged perpendicularly to each other. The end of the first positioning part 71 away from the first limiting part 72 is used to position and install the control panel connector 12. During the molding process, when the control panel connector 12 needs to be installed, the operator inserts the first positioning part 71 with the control panel connector 12 into the installation space. At this time, the first limiting part 72 abuts against the outer wall of the rear side plate mold 4. Then, the first limiting part 72 is fastened to the rear side plate mold 4 with bolts, thereby achieving precise fixing of the entire second positioning module 7. This vertical composite structure not only provides stable support for the second positioning module 7, but also significantly enhances its overall stability during the molding process, ensuring that the fixed control panel connector 12 always maintains the preset positional accuracy in the final product.

[0037] In some embodiments, the top of the left side plate mold 2 and the right side plate mold 3 near the rear side plate mold 4 are respectively provided with a first connecting part 14. Two third positioning modules are provided, and the two third positioning modules are respectively provided on the top of the corresponding first connecting part 14 and the rear side plate mold 4, and are detachably connected to the first connecting part 14 and the rear side plate mold 4.

[0038] Specifically, the top of the left side panel mold 2 and the right side panel mold, near the end of the rear side panel mold 4, are respectively provided with a first connecting part 14, which is used to provide connection support for the third positioning module. There are two third positioning modules, each corresponding to a cover plate connector 13. The two third positioning modules are respectively bolted to the first connecting parts 14 of the left side panel mold 2 and the right side panel mold 3, and are also detachably bolted to the top of the rear side panel mold 4. The detachable connection between the third positioning module and the first connecting part 14 and the rear side panel mold 4 not only facilitates the assembly and disassembly of the mold, but also allows for flexible adjustment of the module in processes such as prepreg layering, further improving the practicality and ease of operation of the mold, and ensuring the molding accuracy and subsequent assembly reliability of the control panel cover plate connector 13.

[0039] In some embodiments, the third positioning module includes: a first positioning element 9 and a second positioning element 10; The first positioning member 9 includes a second positioning part 91 and a first connecting support part 92. The second positioning part 91 is used to abut against the cover plate connector 13 to position the cover plate connector 13. The bottom of the first connecting support part 92 has a first horizontal section and a first inclined section connected to each other. The first inclined section is disposed close to the second positioning member 10. There is a first included angle between the first horizontal section and the first inclined section. The first included angle is an obtuse angle. The opening direction of the first included angle is towards the top of the third positioning module. The first horizontal section is used to abut against the top of the rear side plate mold 4. The first inclined section is used to abut against the first connecting part 14. The second positioning member 10 includes: a third positioning part 101 and a second connecting support part 102. The third positioning part 101 is used to abut against the cover plate connector 13 to position the cover plate connector 13. The bottom of the second connecting support part 102 has an arc-shaped structure and is used to abut against the first connecting part 14.

[0040] Specifically, such as Figures 4-6 As shown, the third positioning module includes a first positioning element 9 and a second positioning element 10, which work together to achieve precise positioning of the cover plate connector 13.

[0041] The first positioning component 9 includes a second positioning part 91 and a first connecting support part 92. The second positioning part 91 is used to abut against the cover plate connector 13 to position the cover plate connector 13. The bottom of the first connecting support part 92 has a first horizontal section and a first inclined section connected to each other. The first inclined section is set close to the second positioning component 10. The first horizontal section and the first inclined section form a first included angle. The first included angle is an obtuse angle and the opening direction is towards the top of the third positioning module. The first horizontal section is used to abut against the top of the rear side plate mold 4, and the first inclined section is used to abut against the first connecting part 14. Through this structural design, the first positioning component 9 is provided with stable support and can be adapted to the overall layout of the mold to ensure the accuracy of positioning.

[0042] The second positioning component 10 includes a third positioning part 101 and a second connecting support part 102. The third positioning part 101 abuts against the cover plate connector 13 to position the cover plate connector 13. The bottom of the second connecting support part 102 is an arc-shaped structure, which abuts against the first connecting part 14. With the adaptability of the arc-shaped structure, a tight fit between the second positioning component 10 and the first connecting part 14 can be achieved, further improving the stability of positioning. Through the above-mentioned structural design of the first positioning component 9 and the second positioning component 10, the cover plate connector 13 can be positioned and constrained from multiple dimensions to ensure its accurate position during the molding process, thereby ensuring the reliability of the subsequent assembly of the cover plate and the control panel body, and also improving the overall structural rationality and ease of operation of the mold.

[0043] In some embodiments, the first connecting portion 14 includes: a first portion and a second portion connected to each other. The first portion is disposed near the rear side plate mold 4 and is disposed in an inclined state. The first portion and the top surface of the rear side plate mold 4 have a second included angle. The second included angle is an obtuse angle and the second included angle is the same as the first included angle. The first portion is used to abut against the first inclined section. The second portion is an arc-shaped groove. The arc-shaped groove is adapted to the shape of the second connecting support portion 102, and the second connecting support portion 102 is disposed in the arc-shaped groove.

[0044] Specifically, the first connecting part 14 includes a first section and a second section that are interconnected. The first section is located near the rear side plate mold 4 and is inclined, forming a second included angle with the top surface of the rear side plate mold 4. This included angle is obtuse and the same as the first included angle of the first inclined section, thereby achieving a tight contact between the first section and the first inclined section and providing stable support for the first positioning member 9. The second section is an arc-shaped groove, the shape of which is adapted to the arc-shaped structure of the second connecting support part 102. The second connecting support part 102 is located in the arc-shaped groove. Through the precise fit of the arc-shaped structure, a reliable connection between the second positioning member 10 and the first connecting part 14 is ensured. This structural design, through the dual matching of angle and shape, not only ensures the precise assembly of each component of the third positioning module with the first connecting part 14, but also provides reliable structural support for the positioning of the cover plate connector 13, improving the overall positioning accuracy and assembly convenience of the mold, and thus ensuring the reliability of the cover plate connector 13 in the molding and subsequent assembly processes.

[0045] In some embodiments, the molding base 1 includes a second horizontal segment 16, an inclined transition segment 18, and a third horizontal segment 17 that are connected to each other. The second horizontal segment 16 and the third horizontal segment 17 are arranged in parallel, and the height of the second horizontal segment 16 is higher than the height of the third horizontal segment 17. One end of the inclined transition segment 18 is connected to the second horizontal segment 16, and the other end is connected to the third horizontal segment 17. The handrail side pressure mold 5 is located on the side of the second horizontal segment 16 away from the third horizontal segment 17, and the rear side plate mold 4 is located on the side of the third horizontal segment 17 away from the second horizontal segment 16.

[0046] Specifically, the molding base 1 includes a second horizontal segment 16, an inclined transition segment 18, and a third horizontal segment 17 that are interconnected. The second horizontal segment 16 and the third horizontal segment 17 are arranged in parallel, and the height of the second horizontal segment 16 is higher than the height of the third horizontal segment 17. One end of the inclined transition segment 18 is connected to the second horizontal segment 16, and the other end is connected to the third horizontal segment 17. This segmented structural design is intended to adapt to the overall outline of the control panel and also to provide spatial support for the layout of the various sub-molds in the side panel assembly. Among them, the armrest side pressing mold 5 is located on the side of the second horizontal segment 16 away from the third horizontal segment 17, and is used to enclose the molding cavity of the control panel armrest functional area; the rear side panel mold 4 is located on the side of the third horizontal segment 17 away from the second horizontal segment 16, and is used to enclose the molding cavity of the rear side area of ​​the control panel. With this layout, the molding base 1 and the side assembly can work together to form a complete cavity that fits the shape of the control panel, providing a precise structural foundation for subsequent processes such as the integral molding of cross reinforcing ribs, the positioning of various metal connectors, and the prepreg layup, ensuring the overall molding accuracy and structural consistency of the control panel.

[0047] In some embodiments, a placeholder block 15 is also provided at the top of the second horizontal segment 16.

[0048] Specifically, a placeholder block 15 is also provided at the top of the second horizontal section 16. The first positioning module 6 is set around the placeholder block 15. The placeholder block 15 is used to occupy space in a specific area during mold assembly and prepreg layering to reserve installation space and avoid misfilling of prepreg in this area. At the same time, it works with the first positioning module 6 and other components to achieve precise positioning in multiple positions, ultimately ensuring the assembly consistency of each component of the control panel and the reliability of the overall structure. This helps the mold to achieve integrated molding of complex cross reinforcing ribs and multi-metal connectors, improving the molding quality and process stability of the product.

[0049] Specifically, the molding process of this application adopts an integral molding method to achieve the coordinated molding of complex cross reinforcing ribs and multi-position metal connectors. The specific process is as follows: Based on product design requirements, accurately calculate the dimensions and number of prepreg layers for reinforcing ribs, overall skin, and local reinforcement areas; After the molding base 1, left side plate mold 2, right side plate mold 3, rear side plate mold 4, handrail side pressure mold 5 and the first positioning module 6 are positioned by positioning pins, they are fastened with bolts to form a molding cavity with cross-distributed rib grooves; during this process, it is ensured that the fit clearance of each mold meets the design requirements; at the same time, the metal embedded part 11 is sleeved on the first positioning module 6 to complete the initial positioning of the metal embedded part 11; After the mold is assembled, the prepreg is cut and the outer skin layer is laid on the surface of the molding cavity according to the design number of layers. After the layering is completed, the rib groove is filled with an expanded rubber mold. The mold is then placed in a vacuum bag and vacuumed. Afterward, it is moved into a hot oven and heated to 60°C for 2 hours to reduce air bubbles generated during the layering process, ensure that the surface layer is tightly bonded to the mold, and improve the surface quality of the product. According to the design layer thickness of the reinforcing ribs, the prepreg is laid in layers in the rib grooves. After each 4mm layer, the mold is placed in a vacuum bag for vacuuming and then subjected to pressure and heat compaction (heat oven at 60℃ for 2 hours) to ensure that the prepreg in the deepest 40mm rib groove is dense and effectively improve the interlayer strength of the product. The prepreg is laid to 90% of the designed thickness to form the structural skin layer. During the laying process, vacuum compaction is performed at a frequency of 1.5mm / time to ensure the interlayer bonding strength. After the laying is completed, the handle functional area is filled with a foam film covered with structural adhesive film (the foam film is designed to expand by 4mm) to ensure the interlayer density in this area. The metal embedded part 11 is fixedly connected to the first positioning module 6 by the positioning pin. Then, the position of the control panel connector 12 is positioned by the second positioning module 7, and the position of the cover plate connector 13 is positioned by the third positioning module, so as to ensure that the control panel connector 12 and the cover plate connector 13 are accurately and stably positioned in the molding cavity. After the metal embedded parts 11, control panel connectors 12, cover plate connectors 13 and structural skin layer are laid, they are pressurized and hot-pressed (60℃ hot-pressed for 2 hours) to ensure that each metal part and structural skin layer are firmly bonded. The prepreg is laid with 10% of the designed thickness to form a covering skin layer. The covering skin layer and the structural skin layer together form the overall skin. The molding mold is moved into the oven and baked at 60℃ for 2-3 hours. After the prepreg softens, it is taken out and all the connecting screws on the handrail side pressure mold 5 are re-tightened to ensure that the mold fitting gap is less than 0.1mm and to ensure the product cavity accuracy. After the completed product is placed in a vacuum bag for vacuuming, the interlayer air is completely removed, and then it is transferred to an autoclave for curing: the temperature is raised to 140°C and an external pressure of 0.8MPa is applied simultaneously to fully cure the prepreg under high temperature and high pressure, ensuring the density and integrity of the product structure. After the high-temperature, high-pressure molding in the autoclave is completed, the demolding process is initiated when the overall temperature drops to the suitable range of 30-50℃. At this time, due to the temperature drop, the expanding rubber mold inside the reinforcing rib cavity shrinks, naturally forming a gap with the inner wall of the reinforcing rib. This allows for easy and complete removal from the complex cross-rib grooves, effectively avoiding any damage to the structure of the reinforcing rib after molding. Subsequently, the side panel components and each positioning module are disassembled in reverse assembly order, and the molded blank is smoothly removed. Finally, the edges and surfaces of the blank are finely trimmed to remove burrs, excess material, and process residues, ultimately resulting in a finished control panel whose shape accuracy and structural strength strictly meet the design requirements. Through the above-described process, the integrated molding of complex cross-reinforcing ribs and multi-position metal connectors is achieved. This not only ensures the integrity of continuous fibers to improve the structural strength of the product, but also ensures the assembly accuracy of the metal connectors and the overall reliability of the product through precise mold positioning and process control. This effectively solves the defects of traditional split molding processes and achieves the technical goals of lightweighting and high stability.
