Description

Technical Field

[0001] This utility model relates to the field of mold preparation technology, and in particular to a mold for preparing an integrated seat cover. Background Technology

[0002] With the development and maturation of one-piece molding technology for foam face covers, this process has been gradually applied to the manufacturing of interior components such as headrests, armrests, and car seats. However, in actual production, especially in the application to car seats, the face cover is difficult to position within the mold, easily resulting in displacement or wrinkles. This leads to surface defects such as unevenness and inconsistent thickness on the molded product, seriously affecting the product yield and even causing batch scrapping, thus hindering the further promotion of this technology.

[0003] To solve the problem of face mask positioning, existing technologies typically use I-shaped positioning pins to fix the face mask inside the mold, or apply adhesive to the surface of the mold cavity to adhere the face mask. However, the former is complex to operate, relies on manual positioning accuracy, and the positioning pins are prone to damaging the face mask; the latter suffers from poor adhesive layer durability and easy contamination of the mold and product surface. Furthermore, during the mold closing and foaming process, the foaming material is prone to overflow from the edge of the molding cavity under high pressure, contaminating the non-molded areas of the face mask, resulting in decreased product cleanliness, increased subsequent finishing processes, and impacting production efficiency and cost control. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a preparation mold for an integrated seat cover that is accurate in positioning, reliable in sealing and easy to operate and maintain.

[0005] The technical solution adopted by this utility model to solve its technical problem is to provide a mold for preparing an integrated seat cover, including an openable upper mold and a lower mold. When the upper mold and the lower mold are closed, they form a cavity for foaming molding. The lower mold is provided with a positioning structure for fixing the periphery of the cover, and a clamping structure is provided between the upper mold and the lower mold. The clamping structure is arranged circumferentially along the cavity and has a clamping surface located on the outer periphery of the cavity and extending continuously circumferentially. When the upper mold and the lower mold are closed, the clamping surface and the peripheral surface of the lower mold or the peripheral surface of the upper mold together clamp the peripheral area of ​​the cover and form a continuous surface contact with the periphery of the cover.

[0006] In the aforementioned mold for manufacturing an integrated seat cover, the pressing structure is independently disposed between the upper mold and the lower mold, and one side of the pressing structure is rotatably connected to the lower mold or the upper mold, while the other side is openably connected to the lower mold or the upper mold.

[0007] In the aforementioned mold for manufacturing an integrated seat cover, the clamping structure is integrated onto the upper mold or the lower mold and welded to the side of the upper mold facing the lower mold or the side of the lower mold facing the upper mold.

[0008] In the aforementioned mold for manufacturing an integrated seat cover, one side of the pressing structure is hinged to the lower mold via a hinge assembly. The hinge assembly includes a first hinge member detachably disposed on the outer wall of the pressing structure and a second hinge member detachably disposed on the outer wall of the lower mold, and the first hinge member and the second hinge member are hinged to each other.

[0009] In the aforementioned mold for manufacturing an integrated seat cover, the other side of the pressing structure is closably connected to the outer wall of the lower mold via a locking assembly. The locking assembly includes a latch on the other side of the pressing structure and a locking tongue on the lower mold. The locking tongue and the latch are releasably engaged to achieve locking.

[0010] In the aforementioned mold for manufacturing an integrated seat cover, the buckle is detachably connected to the clamping structure via fasteners, and the buckle assembly further includes a lock seat detachably disposed on the lower mold, with the lock tongue rotatably disposed on the lock seat.

[0011] In the aforementioned mold for manufacturing an integrated seat cover, the positioning structure includes a plurality of positioning holes arranged along the periphery of the lower mold, and a plurality of positioning pins that correspond one-to-one with the positioning holes and form a plug-in connection.

[0012] In the above-mentioned mold for manufacturing an integrated seat cover, the lower mold extends outward in the horizontal direction on both sides and forms a mounting part. The horizontal projection of the mounting part is outside the horizontal projection of the pressing structure, and the positioning structure is provided on the mounting part.

[0013] In the above-mentioned mold for manufacturing an integrated seat cover, the clamping structure includes a first clamping member, a second clamping member, and a third clamping member with separate designs. The first clamping member is arranged in a ring around the circumference of the cavity. The second clamping member and the third clamping member are respectively welded to the outer wall of the first clamping member, and the second clamping member and the third clamping member are arranged opposite to each other.

[0014] In the aforementioned mold for manufacturing an integrated seat cover, the second or third clamping member is provided with a handle on the side opposite to the first clamping member, and the handle is detachably connected to the second or third clamping member.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. In this utility model, a positioning structure for fixing the periphery of the faceplate is provided on the lower mold, and a clamping structure arranged circumferentially between the upper and lower molds is provided. This clamping structure has a clamping surface located on the outer periphery of the cavity and extending continuously circumferentially. Therefore, when the mold is closed, the clamping surface and the opposite mold surface jointly clamp the periphery of the faceplate and form continuous surface contact. This design not only effectively solves the problem of difficult positioning of the faceplate within the mold, but also effectively prevents the adhesive from overflowing from the cavity edge during foaming, thereby significantly reducing appearance defects such as flash and contamination, and improving molding yield and product consistency.

[0017] 2. In this utility model, the clamping structure is independently located between the upper and lower molds, and one side of the clamping structure is rotatably connected to the lower or upper mold, while the other side is openably connected to the lower or upper mold. This design allows the clamping structure to be rotated open in the mold-open state, facilitating the installation and removal of the faceplate and greatly improving operational convenience. Simultaneously, as an independent module, the clamping structure can be disassembled, maintained, or replaced separately, preventing the entire mold from being scrapped due to localized damage, effectively reducing the maintenance difficulty and operating costs of the mold.

[0018] 3. In this utility model, the clamping structure includes a first clamping component, a second clamping component, and a third clamping component with a separate design. The first clamping component is arranged in a ring along the circumference of the cavity. The second and third clamping components are respectively welded to the outer wall of the first clamping component, and the second and third clamping components are arranged opposite to each other. This design not only reduces the processing and manufacturing difficulty of large clamping structures and improves the precision and assembly flexibility of parts, but also enhances the overall rigidity and expands the contact area with the faceplate through symmetrical layout, ensuring uniform distribution of clamping force and reliable sealing during mold closing, effectively preventing structural deformation and extending the service life of the mold.

[0032] like Figures 1 to 6 As shown, in this embodiment, a mold for manufacturing an integrated seat cover 900 includes an openable upper mold 100 and a lower mold 200. When the upper mold 100 and the lower mold 200 are closed, they form a cavity 300 for foaming molding. The lower mold 200 is provided with a positioning structure 400 for fixing the periphery of the cover 900, and a pressing structure 500 is provided between the upper mold 100 and the lower mold 200. The pressing structure 500 is arranged circumferentially along the cavity 300 and has a pressing surface 501 located on the outer periphery of the cavity 300 and extending continuously circumferentially. When the upper mold 100 and the lower mold 200 are closed, the pressing surface 501 and the peripheral surface of the lower mold 200 or the peripheral surface of the upper mold 100 together clamp the peripheral area of ​​the cover 900 and form continuous surface contact with the periphery of the cover 900. This design not only effectively solves the problem of difficult positioning of the faceplate 900 in the mold, but also effectively prevents the material from overflowing from the edge of the cavity 300 during the foaming process, thereby significantly reducing appearance defects such as flash and contamination, and improving molding yield and product consistency.

[0033] Specifically, such as Figures 1 to 6 As shown, in this embodiment, the mold is suitable for the integrated molding of the cover 900 and the foam material in the foaming process, especially for the production of interior parts such as car seats, headrests, or armrests. Through its integrated structural design, it achieves precise positioning and reliable sealing of the cover 900, effectively improving product molding quality and production efficiency.

[0034] Furthermore, the mold includes an upper mold 100 and a lower mold 200 that can be opened and closed relative to each other. When closed, they together form a cavity 300 for accommodating the cover 900 and performing foam molding. The shape of the cavity 300 matches the contour of the seat component to be molded, ensuring that the foam 910 can be uniformly filled and adhered to the inner surface of the cover 900 after high-pressure injection, achieving structural integration.

[0035] Furthermore, to ensure the motion accuracy and stability during the mold closing process, a guide structure is provided between the upper mold 100 and the lower mold 200 to guide the upper and lower molds 200 to be precisely aligned along a predetermined trajectory, preventing the faceplate 900 from shifting, being damaged, or failing to seal due to misalignment.

[0036] Furthermore, the guiding structure includes mutually cooperating guide posts 220 and guide sleeves 110, forming a typical guide pair. Among them, the guide posts 220 are provided at multiple installation positions on the upper mold 100 or the lower mold 200, while the guide sleeves 110 are correspondingly provided at matching positions on another mold body, realizing a plug-in sliding fit.

[0037] Preferably, guide pillars 220 are located at the four corners of the lower mold 200, extending vertically; guide sleeves 110 are installed at the corresponding corners of the upper mold 100, with their inner holes forming a clearance fit with the outer periphery of the guide pillars 220. When the upper mold 100 descends to close, the guide pillars 220 are gradually inserted into the guide sleeves 110, guiding the upper mold 100 to descend smoothly, ensuring accurate alignment and smooth operation throughout the closing process. This four-point layout has good mechanical symmetry, effectively resisting off-center loads and improving the rigidity and repeatability of the mold operation.

[0038] To address the issues in existing technologies where the faceplate 900 is prone to displacement and wrinkling within the mold, as well as appearance defects caused by material overflow during foaming, this embodiment incorporates a positioning structure 400 on the lower mold 200 for fixing the periphery of the faceplate 900, and a clamping structure 500 arranged circumferentially along the cavity 300 between the upper mold 100 and the lower mold 200. This design, through a synergistic mechanism of "pre-positioning + circumferential sealing," achieves stable fixing and reliable sealing of the faceplate 900, significantly improving the stability of the molding process and the product's appearance quality.

[0039] Furthermore, the positioning structure 400 includes multiple positioning holes 410 arranged along the periphery of the lower mold 200, and multiple positioning pins 420 corresponding one-to-one with the positioning holes 410 and forming a plug-in connection. In actual operation, after the prefabricated faceplate 900 is laid on the lower mold 200, the positioning pins 420 pass through the reserved holes on the edge of the faceplate 900 and are aligned and inserted into the positioning holes 410 of the lower mold 200 one by one, achieving rapid and accurate circumferential fixing. This plug-in connection method has a simple structure and is easy to operate, which can effectively prevent the faceplate 900 from slipping or wrinkling locally due to external force disturbance before mold closing, ensuring that it is always in the ideal forming posture.

[0040] Furthermore, the lower mold 200 extends outwards horizontally on both sides, forming mounting portions 210. The horizontal projection of the mounting portions 210 is outside the horizontal projection of the clamping structure 500, and the positioning structure 400 is located on the mounting portions 210. This design effectively separates the positioning functional area from the clamping sealing area in space, preventing the clamping structure 500 from applying vertical pressure to the positioning pin 420 during mold closing, thereby preventing the positioning pin 420 from bending, breaking, or the edge of the sleeve 900 from being squeezed and damaged. On the other hand, the external mounting portions 210 provide ample operating space for operators or automated fixtures, facilitating the insertion and removal of the positioning pin 420. This is especially suitable for manual mold assembly or robot-assisted loading and unloading scenarios, improving mold assembly efficiency and operational safety.

[0041] Furthermore, the clamping structure 500 is arranged around the outer periphery of the cavity 300, and its main body is located in the parting area of ​​the upper and lower molds 200. It is used to apply a uniform and continuous clamping force to the periphery of the sleeve 900 during the mold closing process, forming a surface contact sealing strip extending in the circumferential direction. This can effectively block the overflow channel of the foaming adhesive 910 during high-pressure injection and prevent the adhesive from seeping out and contaminating the non-molded area of ​​the sleeve 900.

[0042] In a preferred embodiment, the clamping structure 500 is independently disposed between the upper mold 100 and the lower mold 200, forming a detachable or movable intermediate functional module. One side of the clamping structure 500 is rotatably connected to the lower mold 200 or the upper mold 100, while the other side is openably connected to the upper mold 100 or the lower mold 200, thus enabling the clamping structure 500 to have a rotational opening function. When the mold is in the open state, the clamping structure 500 can rotate and open around the rotating side, facilitating accurate placement and positioning of the faceplate 900 by operators or automated equipment; when the mold is closed, the clamping structure 500 closes and is locked, participating in the formation of a complete sealing interface. This design not only improves the ease of clamping the faceplate 900 but also facilitates separate maintenance, cleaning, or replacement of the clamping structure 500, reducing overall mold downtime and maintenance costs.

[0043] Furthermore, one side of the clamping structure 500 is hinged to the lower mold 200 via a hinge assembly 600, forming a basic fulcrum for its rotational opening. The hinge assembly 600 includes a first hinge member 610 detachably disposed on the outer wall of the clamping structure 500, and a second hinge member 620 detachably disposed on the outer wall of the lower mold 200. The first hinge member 610 and the second hinge member 620 are hinged together by a pin, forming a stable rotating pair, allowing the clamping structure 500 to rotate and open around this hinge point. This design facilitates the individual replacement and maintenance of the hinge components, improving the maintainability and service life of the mold. It also supports the overall disassembly of the clamping structure 500, facilitating internal mold cleaning or process adjustment.

[0044] Preferably, the first hinge member 610 is detachably connected to the second clamping member 520 of the clamping structure 500 via fasteners (screws or bolts), and the second hinge member 620 is detachably connected to the lower mold 200 via fasteners. This design is reliable, easy to assemble and disassemble, and suitable for high-frequency maintenance scenarios. It also allows for flexible adjustment of the spatial layout of the hinge points according to the actual installation position, improving assembly accuracy and adaptability.

[0045] To ensure reliable locking of the clamping structure 500 in the mold-closed state, the other side of the clamping structure 500 is closably connected to the outer wall of the lower mold 200 via a locking assembly 700. The locking assembly 700 includes a latch 710 on the other side of the clamping structure 500 and a corresponding latch 720 on the lower mold 200, with the latch 720 and latch 710 releasably engaged to achieve locking. Specifically, when the clamping structure 500 is rotated closed, the latch 710 and latch 720 engage with each other, forming a stable locking state. This prevents the clamping structure 500 from accidentally opening due to vibration or pressure during mold closing or foaming, thereby ensuring the integrity of the sealing interface and the reliability of the molding process.

[0046] Furthermore, the latch 710 is detachably connected to the third clamping member 530 of the clamping structure 500 via fasteners, facilitating replacement or repositioning of the latch 710. The latch assembly 700 also includes a lock seat 730 detachably mounted on the lower mold 200, with the latch tongue 720 rotatably mounted on the lock seat 730, forming a complete locking unit. This modular design allows the latch tongue 720 and lock seat 730 to be maintained or replaced as independent functional units, preventing the entire latch 710 system from failing due to localized wear.

[0047] Preferably, the locking tongue 720 and the locking seat 730 are connected by a pin to achieve rotational engagement, and can be equipped with elastic elements such as torsion springs (not shown in the figure) to enable the locking tongue 720 to have an automatic reset function, thereby improving the smoothness and reliability of the locking action.

[0048] In this embodiment, the clamping structure 500 includes a split-design first clamping member 510, a second clamping member 520, and a third clamping member 530. The first clamping member 510 is arranged in a ring along the circumference of the cavity 300. The second clamping member 520 and the third clamping member 530 are respectively welded to the outer wall of the first clamping member 510, and are arranged opposite to each other. This arrangement enhances structural rigidity and serves as a mounting base for the hinge and the latch 710. This design not only reduces the manufacturing difficulty of the large clamping structure 500 and improves part precision and assembly flexibility, but also enhances overall rigidity through symmetrical layout, expands the contact area with the faceplate 900, ensures uniform clamping force distribution and reliable sealing during mold closing, effectively prevents structural deformation, and extends the mold's service life.

[0049] To improve ease of operation, a handle 800 is provided on the side of the second clamping member 520 or the third clamping member 530 opposite to the first clamping member 510. This handle 800 is detachably connected to the second clamping member 520 or the third clamping member 530 via fasteners, preferably to the third clamping member 530. This design provides the operator with a clear gripping point, facilitating the opening, closing, and adjustment of the clamping structure 500, offering significant ergonomic advantages, especially when space is limited or when working with gloves on. Furthermore, the detachable connection allows the handle 800 to be quickly replaced when not in use or when damaged, without affecting the functionality of the main structure.

[0050] In another embodiment, the clamping structure 500 is integrated onto the upper mold 100 or the lower mold 200 and welded to either the side of the upper mold 100 facing the lower mold 200 or the side of the lower mold 200 facing the upper mold 100. Specifically, the clamping structure 500 is integrally welded to either the side of the upper mold 100 facing the lower mold 200 or the side of the lower mold 200 facing the upper mold 100. This integrated structure is firmly connected to the main mold body through high-strength welding, resulting in higher overall rigidity and structural stability, making it suitable for high-volume, high-cycle automated production lines. This solution can be flexibly selected according to actual production needs.
