Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a quick-change mold for punching and flanging. Background Technology

[0002] Traditional automotive trim punching and flanging dies mostly adopt a single-process common mold base structure. All process components are fixedly installed on an integral upper and lower mold base. Fitters need to rely on a mold closing machine to repeatedly disassemble and assemble the entire mold, which is cumbersome and prone to uneven component gaps due to mold base positioning deviations. Assembly and debugging are difficult, and partial damage requires disassembly of the entire mold, resulting in long downtime and high maintenance costs. Each product requires the independent development of a complete set of mold bases, resulting in poor versatility and high R&D costs. Some dies adopt a detachable mold structure, but they cannot achieve good coordinated fine-tuning of the upper and lower dies. When there are installation deviations between the upper and lower mold bases, it is difficult to quickly adjust the component gaps, which will affect the punching accuracy. Utility Model Content

[0043] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0045] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0046] Traditional automotive trim punching and flanging dies use an integral die base structure, with all process components fixedly installed on a single upper / lower die base. This structure is complex to assemble and debug, requiring repeated disassembly and assembly of the entire die using a die-clamping machine. This is time-consuming and prone to uneven component gaps due to accumulated errors in the die base. Local damage requires disassembling the entire die, resulting in long downtime and high maintenance costs. Each product requires a complete set of custom die bases, leading to poor versatility and high R&D costs. Some dies use detachable modular molds, which facilitate assembly and local maintenance, but cannot solve the problems of fine-tuning the upper and lower dies in coordination and pre-assembly debugging. After changing the die, repeated calibration is required, making the operation complex.

[0047] Please see Figures 1 to 7 This utility model proposes a quick-change die for punching and flanging, including a die frame 100 and multiple quick-change units 200 disposed on the die frame 100. The die frame 100 is composed of an upper die base 110 and a lower die base 120, which are arranged opposite to each other. Each quick-change unit 200 includes an upper die quick-change unit 210 and a lower die quick-change unit 220, which are respectively disposed on the upper die base 110 and the lower die base 120. Specifically, the upper die quick-change unit 210 includes a first base plate 211 and a punch integrated thereon. Component 212, the first base plate 211 is detachably connected to the upper mold base 110 via the first connecting component 213; the lower mold quick-change unit 220 includes a second base plate 221 and a die assembly 222 integrated thereon, the second base plate 221 is detachably connected to the lower mold base 120 via the second connecting component 223; the punch assembly 212 and die assembly 222 of each quick-change unit 200 are arranged opposite to each other and configured to perform corresponding processes such as punching and flanging when the mold is closed. Each process module can be disassembled and repaired independently, reducing downtime, and the upper and lower mold units support offline pre-assembly and debugging, avoiding repeated disassembly and assembly of the whole mold, facilitating assembly and debugging. The universal mold base 100 can also be adapted to multiple products, reducing R&D costs and production mold change time, and improving production efficiency.

[0048] Please see Figures 1 to 7In an optional embodiment of this utility model, the mold frame 100 is provided with multiple sets of quick-change units 200, with each process corresponding to one set of quick-change units 200, including an upper mold quick-change unit 210 and a lower mold quick-change unit 220, i.e., upper and lower molds. In the upper and lower molds corresponding to each process, each component is detachably connected to form a whole, and then detachably installed on a connecting base plate. Finally, it is installed on the mold base through the connecting base plate to form an independent quick-change unit 200. Each mold module can be operated independently in the design, processing, and assembly stages, and then installed as a whole, which greatly shortens the project cycle, improves work efficiency, and ensures progress. The upper and lower mold parts of the quick-change unit 200 can be quickly disassembled on the large mold frame 100, ensuring convenient and quick disassembly on the mold base and machine tool. When changing or repairing the mold, it is only necessary to raise the machine table and remove the upper mold quick-change unit 210 and the lower mold quick-change unit 220 to remove the mold of the corresponding process from the machine table, which greatly improves the efficiency of mold changing and repair, and at the same time makes the operation more convenient and improves production efficiency.

[0049] It should be noted that this mold structure adopts a shared mold base, with each process using a shared large mold frame 100. The specific structure of the mold is not limited; products of similar size can share the large mold base. Only different quick-change units 200 need to be designed according to the product shape. Thus, one mold frame 100 can correspond to multiple products of similar size. Subsequent new product development only requires designing and processing the corresponding quick-change units 200 based on the universal mold frame 100, thereby greatly saving mold development costs and production mold changeover time. The overall mold structure can be comprehensively considered based on product characteristics and machine parameters to allow the universal large mold frame 100 to cover as many products as possible. Furthermore, the external large mold frame can be eliminated, and the machine table can be directly customized, on which the corresponding quick-change units 200 for each process can be installed.

[0050] Please see Figures 1 to 7 In an optional embodiment of this utility model, the mold frame 100 is provided with outer guide posts 130 and outer guide sleeves 140 that cooperate with them. The outer guide posts 130 and outer guide sleeves 140 cooperate to position and ensure the accuracy of mold closing between the upper mold base 110 and the lower mold base 120. Specifically, for example, multiple outer guide posts 130 are provided on the lower mold base 120, and outer guide sleeves 140 that cooperate with multiple outer guide posts 130 are provided on the upper mold base 110. The cooperation of multiple sets of outer guide posts 130 and outer guide sleeves 140 constitutes the guiding system of the mold frame 100, ensuring the accuracy of the mold closing reference of the upper and lower mold bases 120. It should be noted that the mold frame 100 is also provided with necessary components such as limiters 150, quick positioning components 160, and buffer nitrogen 170. The mold frame 100 is fixed to match the machine parameters, and multiple quick-change units 200 are provided on it to correspond to multiple processes. Each quick-change unit 200 corresponding to a process is an independent functional component that can be quickly disassembled and changed.

[0051] Please see Figures 1 to 7 In an optional embodiment of this utility model, the upper mold quick-change unit 210 includes a first base plate 211 and a punch assembly 212 integrated thereon. The first base plate 211 is connected to the upper mold base 110 through a first connecting assembly 213, such as a fixing bolt. The first base plate 211 has a corresponding threaded hole. The fixing bolt passes through the bottom of the upper mold base 110 and connects with the threaded hole to fix the first base plate 211 to the upper mold base 110, and ensures that the base plate can be removed from the reverse side after the machine tool is raised. The punch assembly 212 is fixed to the upper mold base 110 through the first base plate 211. When the mold for a certain process needs to be disassembled and replaced, the upper mold quick-change unit 210 can be completely removed by simply removing the corresponding fixing bolt.

[0052] Please see Figures 1 to 7 In an optional embodiment of this utility model, the punch assembly 212 includes an upper clamping plate 2121, an upper pressure plate 2122, an inner guide post 2123, a backing block 2124, and a punch 2125. The upper clamping plate 2121 is fixed to the first base plate 211 and is used to install and fix other mold components. It is a rigid support base to ensure the overall structural strength of the assembly. The inner guide post 2123 is connected to the first base plate 211 through the upper clamping plate 2121. The inner guide post 2123 penetrates the upper pressure plate 2122 and extends beyond the lower end of the upper pressure plate 2122. It cooperates with the inner guide sleeve 2221 to position the upper mold quick-change unit 210 and the lower mold quick-change unit 220, thus forming the quick-change unit 20. The guiding system of the die set 100, together with the outer guide post 130 and outer guide sleeve 140 system, forms a dual positioning architecture to eliminate assembly deviations. The upper pressure plate 2122 is connected to the inner guide post 2123. The upper pressure plate 2122 applies pressure and fixes the material to prevent deformation or displacement during the stamping process. The punch 2125 is connected to the upper pressure plate 2122 and cooperates with the die assembly 222 to realize stamping and other processes. A support block 2124 is also provided on one side of the upper pressure plate 2122 to provide lateral support, resist the radial force generated during the stamping process, ensure the alignment accuracy of the cavities of the punch 2125 and the die 2224, and ensure the stability of the workpiece forming angle. It is understood that the positioning structure is not limited. In other embodiments, other positioning mechanisms such as tapered positioning pins can also be used to achieve the positioning and cooperation of the upper and lower parts of the structure.

[0053] Please see Figures 1 to 7In an optional embodiment of this utility model, the length of the inner guide post 2123 extending beyond the lower end of the upper pressure plate 2122 is greater than the stroke of the upper pressure plate 2122. Specifically, for example, the length of the inner guide post 2123 extending beyond the lower end of the upper pressure plate 2122 is L, and the stroke of the upper pressure plate 2122, i.e., the stroke of the upper mold quick-change unit 210, is S, where L ≥ S + 30 mm. This length design ensures the pre-guiding effect during the mold closing process. The inner guide post 2123 can maintain its engagement with the lower mold inner guide sleeve 2221 throughout the entire process, achieving precise guidance of the quick-change unit 200 and avoiding repeated adjustments caused by separate assembly. It is understood that the length L can be adjusted according to the adaptability of the mold structure. For example, in a large-stroke mold, it can be extended to S + 50 mm, as long as the mold closing accuracy is guaranteed without affecting the reliability of the stamping action.

[0054] Please see Figures 1 to 7 In an optional embodiment of this utility model, a guide groove 121 is provided on the lower mold base 120, which extends along the width direction of the lower mold base 120 and has an open end. The second base plate 221 is disposed in the guide groove 121. According to the size of the base plate, an opening groove is milled on the lower mold base 120 to guide the two sides of the base plate, thereby improving installation efficiency and ensuring accuracy. The guide groove 121 provides quick insertion and insertion positioning, which can cooperate well with the fine adjustment mechanism to compensate for assembly errors. When changing the mold, only the clamping parts need to be disassembled to horizontally pull out the base plate, thereby improving efficiency.

[0055] Please see Figures 1 to 7 In an optional embodiment of this utility model, the lower mold quick-change unit 220 includes a second base plate 221 and a cavity mold assembly 222 integrated thereon. The second base plate 221 is connected to the lower mold base 120 via a second connecting assembly 223. The second connecting assembly 223 is an adjustable locking mechanism, which can achieve fine-tuning and fixing of the position of the second base plate 221 by cooperating with the inclined surfaces at both ends of the second base plate 221. It is understood that although the upper and lower mold parts have been fitted together before being installed on the mold frame 100, after they are installed on the mold base, gap deviations may occur between the upper and lower parts due to factors such as positioning deviations, processing deviations, and human installation deviations of the upper and lower mold bases 120. By fine-tuning the position of the second base plate 221 through the second connecting assembly 223, the gap deviation between the upper and lower molds can be eliminated, and the gap between the upper and lower parts can be quickly adjusted to be uniform.

[0056] Please see Figures 1 to 7In an optional embodiment of this utility model, the second base plate 221 is provided with a first inclined surface 2211 and a second inclined surface 2212 at both ends. The second connecting component 223 is configured to fine-tune the position of the second base plate 221 by cooperating with the first inclined surface 2211 and the second inclined surface 2212. The second connecting component 223 includes a first adjusting member and a second adjusting member. The first adjusting member is connected to the lower mold base 120, with one end abutting against the end face of the guide groove 121 and the other end abutting against the first inclined surface 2211. The second adjusting member is located at the end of the second base plate 221 away from the first adjusting member, and is connected to the lower mold base 120 and abutting against the second inclined surface 2212. The guide groove 121 accurately positions the two sides of the second base plate 221 to prevent it from shifting. The first adjusting member and the second adjusting member cooperate to drive the second base plate 221 to move along the width direction of the lower mold base 120 within the guide groove 121 to fine-tune its position.

[0057] Please see Figures 1 to 7 Specifically, the first adjusting component includes a slanted pressure block 2231. The surface of the slanted pressure block 2231 that contacts the first inclined surface 2211 is set as a matching inclined surface. The slanted pressure block 2231 is connected to the lower mold base 120 by an adjusting bolt. When the adjusting bolt is tightened, the slanted pressure block 2231 is driven to move along the first inclined surface 2211, forcing the second base plate 221 to move horizontally. The second adjusting component includes a locking bolt 2232, the axis of which is perpendicular to the second inclined surface 2212. The lower mold base 120 is provided with an inclined threaded hole that cooperates with the locking bolt 2232. After the bolt is screwed in, the end abuts against the second inclined surface 2212 to achieve rigid locking. A shim can also be provided between the locking bolt 2232 and the second inclined surface 2212 to prevent wear caused by repeated disassembly and assembly. By utilizing the cooperation between the first inclined surface 2211 and the third inclined surface of the inclined pressure block 2231, the adjusting bolt of the inclined pressure block 2231 is adjusted by pushing the second base plate 221 horizontally through the inclined surface, thereby achieving fine adjustment of the position of the second base plate 221. Simultaneously, the locking bolt 2232 cooperates to adjust and fix the second base plate 221, ensuring that the second base plate 221 can be quickly pulled out from the lower die holder 120 by removing the locking bolt 2232, making operation convenient. Precise fine adjustment can be achieved through the horizontal component of the inclined surface of the inclined pressure block 2231, while the locking bolt 2232 applies pressure perpendicular to the second inclined surface 2212. This cooperation achieves fine adjustment while eliminating gap vibration, ensuring stamping stability. When replacing or repairing the die, simply remove the locking bolt 2232 on the inclined surface to completely remove the lower die quick-change unit 220 for the corresponding process. The structure is simple and the operation is convenient.

[0058] Please see Figures 1 to 7In an optional embodiment of this utility model, a threaded hole for engaging with the locking bolt 2232 is provided on the lower mold base 120. To ensure the stable and reliable fixing of the second base plate 221, the locking bolt 2232 is set perpendicular to the second inclined surface 2212, with the bolt head abutting against the second inclined surface 2212. That is, the locking bolt 2232 is inclined relative to the horizontal plane, and the threaded hole is also inclined accordingly. An avoidance groove 122 is provided on the lower mold base 120 so that the locking bolt 2232 can be well engaged with the threaded hole to achieve fixation and avoid structural interference. A groove is opened on the second inclined surface 2212 of the second base plate 221, and the locking bolt 2232 is set in the groove for easy installation and to avoid interference. In other embodiments, the structure of the second connecting component 223 can also be configured in other ways. For example, inclined pressure blocks 2231 can be used at both ends of the second base plate 221 to achieve position adjustment, or an eccentric wheel clamping mechanism can be used to achieve fine-tuning and fixation of the position.

[0059] It is understood that in other embodiments, the first connecting component 213 can be configured as an adjustable locking mechanism, the second connecting component 223 can be configured as a fixed mechanism, or both can be configured as adjustable locking mechanisms, etc., so as to achieve fine adjustment of the relative position between the upper mold quick change unit 210 and the lower mold quick change unit 220.

[0060] Please see Figures 1 to 7 In an optional embodiment of this utility model, the die assembly 222 includes components such as an inner guide sleeve 2221, a lower float block 2222, a positioning block 2223, and a die 2224. The inner guide sleeve 2221 and the inner guide post 2123 of the punch assembly 212 cooperate to form a guiding system to eliminate die closing deviation. The lower float block 2222 is supported on the second base plate 221 by an elastic element, which dynamically buffers the stamping force during the stamping process to adapt to the processing requirements of different material thicknesses and deformation amounts. The positioning block 2223 is located at the feeding end of the die 2224 to ensure that the material to be processed is accurately positioned before die closing. The cavity contour of the die 2224 matches the punch 2125 to perform punching / flanging forming and other processes.

[0061] Please see Figures 1 to 7In an optional embodiment of this utility model, after the punch assembly 212 or die assembly 222 of each quick-change unit 200 is designed and manufactured, it is closed and debugged outside the mold frame 100. Then, the debugged upper mold quick-change unit 210 and lower mold quick-change unit 220 are installed into the mold frame 100 through the connecting assembly, and the position of the second base plate 221 is calibrated by the inclined plane mechanism to eliminate the gap deviation between the upper and lower molds. When mold replacement and maintenance are required, only the connecting parts need to be disassembled, and the problematic module (a certain quick-change unit) can be completely removed and replaced. Through independent modular design, and all intermediate functional components of the mold are designed as independent quick-disassembly and quick-change parts, after single-sequence assembly and debugging, they are installed into the mold frame 100 in sequence. The single-sequence components are small and lightweight compared to the large mold base, which is very convenient for mold assembly. If any problems occur during the production trial molding process, the problematic upper or lower mold part can be easily and quickly removed from the machine and the problem can be quickly found off-machine.

[0062] In summary, this utility model, through the design of a double quick-change unit for upper and lower dies, allows for the individual design, processing, and assembly of each module before overall installation. Each independent module and its components can also be quickly disassembled. Furthermore, the universal mold frame can cover multiple products, increasing the convenience of mold assembly and debugging for fitters, significantly shortening project cycles, improving production efficiency, reducing mold changeover time, and lowering R&D costs. The micro-adjustment mechanism compensates for assembly errors, ensuring precise mold fit and reducing product defect rates. It solves the problems of cumbersome disassembly and assembly, long debugging cycles, and poor versatility of quick-change dies for punching and flanging, effectively improving efficiency, reducing costs, facilitating maintenance, and providing good versatility.
