Description

Technical Field

[0001] This utility model belongs to the field of shaping molds, specifically relating to a shaping mold used for punching holes on the side of the glass guide rail on the front door. Background Technology

[0002] In modern automobile body manufacturing, the sealing performance, operational smoothness, and appearance quality of the door system have a significant impact on the overall vehicle performance. Among them, the upper glass rail of the front door, as a key support component of the window glass lifting mechanism, is usually a long strip metal component made of high-strength cold-rolled steel sheet or aluminum alloy profile through roll forming process. This upper glass rail of the front door (usually a long strip metal profile) requires stamping of multiple positioning holes on its side wall and shaping of the rail to meet assembly accuracy requirements.

[0003] Currently, the industry generally adopts a step-by-step stamping process: first, all lateral holes are stamped in a dedicated punching die, and then the semi-finished product is transferred to another forming die for shape correction. Since the punching and forming processes are performed in different dies, there is a positioning deviation in each clamping. In addition, the waiting time for material handling and loading / unloading makes it difficult to meet the needs of high-speed, continuous production in modern automobile manufacturing.

[0007] A shaping component is symmetrically arranged on both sides of the contour block. The shaping component includes an elastic element and a shaping block. The two ends of the elastic element are respectively connected to the shaping block and the driving end of the shaping component.

[0015] In the above-mentioned forming mold for punching holes on the side of the glass guide rail on the front door, the bottom of the driving block is provided with a non-communicating limiting groove and a mounting groove. The lower mold base is provided with a limiting block and a driving component. The limiting block extends into the limiting groove and is clearance-fitted with it. The output end of the driving component is provided with a connecting block. The connecting block is connected to the inner wall of the mounting groove to push the driving block to move relative to the lower mold base.

[0016] In the above-mentioned forming mold for punching holes on the side of the glass guide rail of the front door, friction blocks can be detachably installed on the side wall of the pressure block and the driving inclined surface.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention provides a shaping mold for punching holes on the side of the glass guide rail on the front door. It integrates the shaping and punching functions into the same mold. Through the linkage drive of the pressing component and the change of the punching gap formed by the elastic element, it realizes the orderly composite processing of "punching first and shaping later". This not only avoids the cumulative error caused by multiple positioning in the traditional process and improves the product size accuracy and consistency, but also significantly shortens the production cycle and improves the overall processing efficiency.

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0037] like Figures 1 to 6As shown, this utility model discloses a shaping mold for punching holes on the side of a glass guide rail 1 on a front door, used to shape and punch holes in the guide rail 1. It includes: a lower mold base 2, equipped with a contour block 20, which restricts the horizontal movement of the guide rail 1; a shaping assembly 3, symmetrically arranged on both sides of the contour block 20, the shaping assembly 3 including an elastic element 30 and a shaping block 31, the two ends of the elastic element 30 being connected to the shaping block 31 and the driving end of the shaping assembly 3 respectively; a punching gap 330 formed between the shaping block 31 and the driving end, and the shaping block 31 movably abutting against the side wall of the guide rail 1; and a punching assembly 4. The punching component 4, located within the forming component 3, includes a punching block 40 extending into the forming block 31 and movably inserted into the guide rail 1. A pressure component 5 is movably positioned above the lower die base 2. When the pressure component 5 is in contact with the lower die base 2, it drives the forming component 3 to slide relative to the lower die base 2. When the forming block 31 is pressed against the side wall of the guide rail 1, the punching gap 330 gradually decreases due to the movement of the forming component 3, allowing the punching block 40 to be punched and formed within the guide rail 1. When the driving end is pressed against the forming block 31, the forming component 3 pushes the forming block 31 to adjust the curvature of the guide rail 1.

[0038] In this embodiment, the front door upper glass guide rail 1 is a bent component. Due to the quality requirements of automotive sealing, the curvature of the guide rail 1 needs to be further shaped to meet the required usage standards. Specifically, as follows... Figures 1 to 6 As shown, a worker or robot can tightly fit the outer contour of the guide rail 1 against the contour block 20 to achieve initial positioning. As the pressure assembly 5 moves downward, it can press and clamp the top wall of the guide rail 1 to prevent displacement or rotation during subsequent punching and shaping processes; Figure 3 As shown, it should be noted that before shaping, a punching gap 330 is formed between the shaping block 31 and the shaping component 3 (i.e., there is a certain distance, and the elastic element 30 is in an expanded state). As the pressure component 5 continues to descend, it can push the shaping component 3 to slide horizontally along the direction of the contour block 20. During this process, the elastic element 30 and the punching component 4 remain relatively stationary with the shaping component 3 until the shaping block 31 is pressed against the side wall of the guide rail 1. When the shaping component 3 continues to approach the lower mold base 2, the elastic element 30 is gradually compressed along the direction of the shaping block 31 due to the continued sliding of the shaping component 3. At this time, the shaping block 31 has not yet performed a shaping operation on the guide rail 1, but only provides a guiding function for the punching component 4, ensuring that the shaping component 3 can drive the punching block 40 to punch and form holes on the side wall of the guide rail 1 during the subsequent continued sliding. As the punching action is completed and the shaping component 3 is pressed against the shaping block 31 (refer to...), the shaping component 3 can push the shaping component 3 to slide horizontally along the direction of the contour block 20. Figure 3As shown in the structure, the punching gap 330 is zero at this time. The re-movement of the shaping component 3 will inevitably lead to rigid contact with the shaping block 31. When a driving force is applied to the shaping block 31 along the direction of the contour block 20, the sidewall of the guide rail 1 will undergo plastic deformation to achieve the required curvature. Therefore, this shaping die integrates shaping and punching functions into the same mold. Through the linkage drive of the pressure component 5 and the change in the punching gap 330 formed by the elastic element 30, it achieves an orderly composite processing of "punching first, then shaping." This not only avoids the cumulative errors caused by multiple positioning in traditional processes, improving product dimensional accuracy and consistency, but also significantly shortens the production cycle and improves overall processing efficiency.

[0039] The pressing assembly 5 also includes a pressing block 50. The driving end of the shaping assembly 3 is connected to a driving block 32. The two ends of the elastic element 30 are respectively connected to the driving block 32 and the shaping block 31, and a punching gap 330 is formed between the driving block 32 and the shaping block 31. The pressing block 50 is movably pressed against the driving block 32 to push the driving block 32 to slide relative to the lower die base 2.

[0040] like Figures 1 to 3 As shown, this embodiment adds a pressure block 50 to the pressure assembly 5 and sets the driving end of the shaping assembly 3 as a driving block 32, so that the elastic element 30 is connected between the driving block 32 and the shaping block 31, thereby forming the required punching gap 330 to provide sufficient time for the punching action. It also effectively converts the downward pressure force into horizontal driving motion. This design allows the pressure action to not only fix the workpiece but also directly trigger the shaping and punching actions, simplifying the power transmission path, improving the synchronization and response speed of the actions, and enhancing the coordination and reliability of the overall mold action.

[0041] A pressing inclined surface 500 is formed on the pressing block 50, and a driving inclined surface 320 is formed on the driving block 32. The pressing inclined surface 500 movably abuts against the driving inclined surface 320. Figure 3 As shown, this embodiment utilizes the cooperative design of two inclined surfaces to realize a wedge-type transmission mechanism. When the pressure block 50 moves downward, its pressure inclined surface 500 pushes the driving inclined surface 320 on the driving block 32 to generate a horizontal component force, thereby driving the driving block 32 to slide along the direction of the contour block 20. This inclined surface transmission method has a compact structure and stable force transmission, and can achieve a smooth transition from vertical to horizontal movement, reducing impact and wear, and extending the mold life. It is particularly suitable for side punching application scenarios with limited space.

[0042] The pressing assembly 5 also includes a pressing block 51 and a nitrogen spring. The pressing block 51 is used to press the guide rail 1 onto the contour block 20; the nitrogen spring is located inside the pressing block 50.

[0043] like Figure 2As shown, during the downward movement of the pressing assembly 5, the pressing block 51 in this embodiment pre-compacts the pressing operation on the guide rail 1 to ensure that the guide rail 1 maintains absolute stability during subsequent punching and shaping operations, preventing it from affecting the overall processing quality due to shaking or tilting. During this process, the pressing block 50 pushes the driving block 32 to slide along the direction of the contour block 20. After the pressing block 51 presses the guide rail 1, there is still a certain distance between the shaping block 31 and the guide rail 1. At this time, the characteristics of the nitrogen spring (not shown in the figure) can be used to continue to drive the pressing block 50 downward for a certain distance. For this reason, the driving block 32 continues to push the shaping block 31 closer to the contour block 20 until the shaping block 31 presses against the guide rail 1. At the same time, the punching block 40 completes the side punching operation on the guide rail 1. Therefore, the combination design of the clamping block 51 and the nitrogen spring in this embodiment ensures that the pressing assembly 5 not only has sufficient clamping force to prevent the guide rail 1 from shifting or deforming during the punching process, but also has good buffering performance; at the same time, the nitrogen spring provides stable and controllable preload. It should be noted that the nitrogen spring in this embodiment is a new type of elastic component that uses high-pressure nitrogen as the working medium. It is small in size, has high elastic force, long stroke, stable operation, precise manufacturing, long service life, gentle elasticity curve, and does not require preload, etc. It can perform tasks that are difficult for conventional elastic components such as metal springs, rubber, and air cushions to accomplish. The structure and working principle of this nitrogen spring are existing technologies and will not be described in detail here.

[0044] The drive block 32 is provided with a first wedge 321, and the punching assembly 4 also includes a second wedge 41 placed in the shaping block 31. The second wedge 41 is provided with a guide hole 410. The punching block 40 is detachably connected to the first wedge 321 and is movably inserted into the guide hole 410.

[0045] like Figures 3 to 5 As shown, in this embodiment, both the first wedge block 321 and the second wedge block 41 can be disassembled and assembled using screws, bolts, and other components, making the overall operation convenient. This also facilitates the maintenance and replacement of subsequent components, effectively avoiding large-scale replacement of the entire drive block 32 and shaping block 31, thus reducing maintenance costs. In addition, in this embodiment, the punching block 40 is movably disposed within the guide hole 410. As the shaping block 31 adheres to the side wall of the guide rail 1, the guiding effect of the guide hole 410 ensures that the punching block 40 achieves stable punching operation, ensuring the straightness and centering of the punching block 40 during movement, and avoiding edge wear or breakage caused by off-center loading. Furthermore, the detachable design of the punching block 40 facilitates replacement and maintenance, improving the versatility and maintenance convenience of the mold.

[0046] The bottom of the drive block 32 is provided with a non-communicating limiting groove 322 and a mounting groove 323. The lower mold base 2 is provided with a limiting block 21 and a drive component 22. The limiting block 21 extends into the limiting groove 322 and is clearance-fitted with it. The output end of the drive component 22 is provided with a connecting block 220. The connecting block 220 is connected to the inner wall of the mounting groove 323 to push the drive block 32 to move relative to the lower mold base 2.

[0047] like Figure 6 As shown, in this embodiment, the clearance fit structure between the limiting groove 322 and the limiting block 21 provides guidance and limiting functions during the movement of the driving block 32, preventing it from shifting or jamming and ensuring smooth movement; while the connection between the mounting groove 323 and the connecting block 220 achieves efficient transmission of the output force of the driving component 22 (nitrogen cylinder / nitrogen spring). Therefore, when the nitrogen spring presses the driving block 32 against the shaping block 31 (refer to the material pressing block 50)... Figure 3 (As shown in the state), at this time, the shaping block 31 is close to the side wall of the guide rail 1, and the side wall of the guide rail 1 is punched by the punching block 40. As the driving component 22 pushes the driving block 32 to slide more precisely through the connecting block 220, the arc-shaped shaping operation of the guide rail 1 can be realized. This structure realizes precise control of the driving action, improves the repeatability and positioning accuracy of the mold action, and ensures the consistency and accuracy of the shaping operation.

[0048] Friction blocks 501 can be detachably installed on the side wall of the pressure block 50 and the driving inclined surface 320. A partition column 23 is also configured on the lower mold base 2. The side wall of the partition column 23 and the pressure inclined surface 500 are movable against the friction block 501.

[0049] like Figure 1 and Figure 3 As shown, in this embodiment, the pressure plate 500 and the drive plate 320 are high-frequency sliding contact areas, which are prone to surface scratches, seizing, or wear due to metal friction. Therefore, by detachably installing friction blocks 501 (materials can be polytetrafluoroethylene, graphite copper, wear-resistant nylon, or nitrided steel) on both plates, wear is concentrated on vulnerable parts. This means that after the friction blocks 501 wear, only small parts need to be replaced, avoiding the need to replace the entire expensive pressure plate 50 or drive plate 32, significantly reducing maintenance costs. It should be noted that the friction blocks 501 can be disassembled and reassembled using screws and other connecting parts for regular replacement, extending the service life of critical moving parts. In addition, the baffle post 23 in this embodiment also guides and limits the downward movement of the pressure plate 50, preventing it from tilting or wobbling due to the reaction force from the drive plate 320 on the drive plate 32, ensuring the smoothness and stability of the entire punching operation.

[0050] The lower mold base 2 is provided with a first fixed seat 24, and a guide post 240 and a buffer spring 241 are connected inside the first fixed seat 24. The pressing assembly 5 is provided with a second fixed seat 52, and a guide hole 520 is opened inside the second fixed seat 52. When the guide post 240 is movably inserted into the guide hole 520, the second fixed seat 52 can be movably pressed against the buffer spring 241.

[0051] like Figure 1 and Figure 2 As shown, this embodiment forms a double-guided + buffered pressing guide mechanism by setting a first fixed seat 24 in the lower die base 2 and configuring a guide post 240 and a buffer spring 241 therein, and setting a matching second fixed seat 52 and guide hole 520 on the pressing assembly 5. This structure not only ensures the vertical accuracy of the pressing assembly 5's up and down movement, ensuring the accuracy of the entire pressing operation and punching and shaping operation, but also allows the buffer spring 241 to absorb impact energy when the pressing material is in place, reducing vibration and noise, protecting the die structure, and improving the smoothness and safety of operation. It is especially suitable for high-frequency continuous stamping operations.

[0052] The pressing assembly 5 is also connected to a straightening block 53, and a straightening groove 25 is formed on the lower mold base 2. The straightening block 53 is movably engaged in the straightening groove 25.

[0053] Furthermore, such as Figure 1 and Figure 2 As shown, the movable snap-fit ​​structure between the straightening block 53 and the straightening groove 25 provides additional lateral (i.e., horizontal) constraint for the pressure assembly 5, preventing it from twisting or shifting laterally during movement. This structure enhances the overall rigidity and positioning accuracy of the pressure assembly 5, ensuring uniform distribution of pressure force and avoiding problems such as deformation of the guide rail 1 or burrs in the punching caused by uneven pressure, further improving the dimensional stability and appearance quality of the product. Preferably, in this embodiment, the aforementioned friction block 501 structure can be detachably connected to the inner wall of the straightening groove 25, which helps to reduce the wear of the straightening block 53.

[0054] The lower mold base 2 is detachably connected to an anti-detachment block 26, which is close to the contour block 20 and moves against both ends of the guide rail 1 in the length direction.

[0055] like Figure 1 As shown, in this embodiment, the anti-detachment block 26 is detachably connected to the lower mold base 2 and closely adheres to the contour block 20, which can effectively prevent the guide rail 1 from accidentally sliding out in the length direction, prevent the workpiece from falling off during loading, unloading or stamping, and improve operational safety. This structure facilitates quick replacement and adaptation according to different guide rail 1 models, enhances the flexible production capability of the mold, adapts to the production needs of multiple varieties and small batches, and improves equipment utilization.

[0056] It should be noted that the elastic element 30 in this embodiment can be replaced by other elastic devices such as compression springs and return springs.
