Description

Technical Field

[0001] This invention relates to the field of molds, and in particular to a multi-structure shaping mold for shaping. Background Technology

[0002] Forming molds are mainly used for secondary correction of aluminum alloy die castings. By applying pressure, they correct deformation and dimensional deviations that occur during the cooling process, ensuring that the geometric accuracy meets assembly requirements. However, existing new energy battery tray aluminum alloy die castings come in a wide variety of specifications and shapes. Traditional forming processes typically use a one-size-fits-all integrated workbench structure, meaning that each die casting specification must be equipped with an independent, non-separable dedicated workbench and mold. This results in the entire workbench and mold having to be removed from the production line and replaced when producing different models of products, making the operation cumbersome. Furthermore, it requires companies to maintain a large number of dedicated workbenches for each product, significantly increasing equipment manufacturing costs and warehousing space requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-structure shaping mold for shaping, which solves the problems of single structure and poor versatility of existing shaping molds, making the shaping mold more adaptable and easier to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-structure shaping mold for shaping, comprising a worktable, wherein the worktable is provided with an upper mold, a lower mold, an inner mold mechanism and an outer mold mechanism, wherein the upper mold and the lower mold are slidably engaged by guide posts, the guide posts being used to guide the upper mold and the lower mold to close, wherein the lower mold is provided with first mounting positions for mounting the inner mold mechanism and the outer mold mechanism respectively, wherein the inner mold mechanism and the outer mold mechanism each include a mounting base, a slider slidably disposed on the mounting base, a driver for driving the slider to slide, and a shaping block detachably mounted on the slider, wherein the slider, the driver and the mounting base are connected as one unit, and the mounting base is detachably mounted on the first mounting position.

[0005] After adopting the above technical solution, the present invention has the following advantages: By setting the inner mold mechanism and outer mold mechanism as an integral structure that can be independently disassembled and replaced, and matching them with detachable forming blocks, and pre-connecting the slider, driver and mounting base as a whole to form a modular component, when it is necessary to change to different specifications of products for forming operations, it is not necessary to disassemble the entire worktable. The modular inner mold mechanism or outer mold mechanism can be directly replaced as a whole, or the individual forming blocks can be replaced. The complex process that requires the disassembly of multiple parts in the traditional way is simplified to a single operation of disassembling and assembling the mounting base or forming block for the first mounting position, which greatly reduces the number of replacement steps, can significantly shorten the waiting time for production changeover, and improve the operating efficiency of the production line; at the same time, the same worktable can be shared. It is only necessary to store inner mold mechanisms, outer mold mechanisms and forming blocks of different specifications. By replacing different specifications of inner mold mechanisms, outer mold mechanisms and forming blocks, the forming needs of different positions and features of various forming parts can be flexibly adapted. For point features such as protrusions, pits or pin holes on die castings, forming blocks with corresponding forming surfaces are selected, and precision is achieved through stamping. For linear features such as ribs, edges, or guide rails, a long strip or guide rail-shaped inner mold is used in conjunction with an outer mold to apply pressure along a straight trajectory to complete the linear positioning. For planar features such as flat surfaces, curved surfaces, or stepped surfaces, a large-area fitting shaping block or combination mold is used for surface positioning. Furthermore, for the shaping requirements of the upper and lower end faces of thin-walled workpieces, this invention uses an inner mold mechanism and an outer mold mechanism to simultaneously clamp the inner and outer sides of the thin-walled workpiece, providing stable support for the vertically erected thin-walled workpiece during the upper and lower shaping process, and preventing the thin-walled workpiece from bending and deforming due to force as much as possible, thereby solving the problem of easy deformation of the side walls when shaping the two ends of a vertically erected thin-walled workpiece. For complex die-cast products, the aforementioned internal and external mold mechanisms with different functions can be mixed and installed and operate in a coordinated manner, flexibly combining point, line, and surface shaping units. This allows for the completion of all-round shaping requirements for complex die-cast parts in a single process or continuous workstation, significantly reducing the material cost of mold production and minimizing storage space occupation. At the same time, the coordinated setup of the upper mold, lower mold, internal mold mechanism, and external mold mechanism enables multi-dimensional shaping of die-cast parts from the top and bottom and the inner and outer sides, achieving correction of multiple surfaces of the product. It can also achieve shaping by clamping the upper and lower molds in the same position or by clamping the internal mold mechanism and the external mold mechanism in the same position, ensuring that the stress points of the workpiece are in the same position both vertically and horizontally, and more accurately fulfilling the dimensional requirements of the shaping.

[0006] Furthermore, the shaping block is either floatingly mounted on the slider or fixedly mounted on the slider.

[0007] When using the aforementioned technical solution, the relative position of the forming block and the slider is stable when the fixed installation method is adopted, which ensures the forming dimensional accuracy and repeatability accuracy as much as possible and meets the requirements of high-precision forming. When the floating installation method is adopted, the forming block can adaptively adjust its posture and position within a certain range, which can adapt to the surface of products with different shapes and sizes. It can also compensate for the dimensional deviation of the casting itself, the mold assembly error, and the force offset during the forming process, and avoid local overpressure, cracking or dimensional deviation of the casting caused by rigid extrusion as much as possible, thereby improving the forming effect. At the same time, the two installation methods can be switched as needed according to the actual production conditions, which further enhances the adaptability and flexibility of the multi-structure forming mold for aluminum alloy die castings of new energy battery trays with different specifications and structures.

[0008] Furthermore, the shaping block is provided with a shaping plane or a shaping curved surface.

[0009] By adopting the aforementioned technical solution, the corresponding shaping plane or shaping curved surface can be selected for shaping operations according to the shape characteristics and precision requirements of different parts of the product, thereby improving the versatility of the shaping block.

[0010] Furthermore, the slider is provided with a plurality of second mounting positions for mounting the shaping block, and the plurality of second mounting positions are spaced apart.

[0011] By adopting the aforementioned technical solution, on the one hand, the second mounting position of the shaping block can be flexibly selected according to the product's shaping area distribution, size, and deformation correction requirements, so as to realize the free combination and layout adjustment of the shaping points and meet the differentiated correction requirements of different parts or different specifications of the same product; on the other hand, the structure with multiple second mounting positions spaced apart can adapt to the shaping contour and size of different models of products by simply adjusting the assembly position of the shaping block on the second mounting position without changing the slider and mounting base, thereby further improving the universality of the inner mold mechanism and the outer mold mechanism.

[0012] Furthermore, the inner mold mechanism is provided with a pair of sliders, and the inner mold mechanism also includes a linkage for simultaneously connecting the pair of sliders. The driving end of the driver is connected to the linkage, and the driver drives the pair of sliders to move towards each other or away from each other through the linkage.

[0013] With the above technical solution, a single driver can synchronously drive a pair of sliders to move in opposite directions or back to back. This structure eliminates the complex arrangement of configuring a separate driver for each slider, greatly simplifying the overall structure of the inner mold mechanism. At the same time, a single driver can achieve synchronous movement of the two sliders through linkage components, effectively improving the shaping efficiency.

[0014] Furthermore, the linkage includes a push block, which is fixedly connected to the drive end of the driver, and the two sides of the push block and the paired sliders are respectively inclined to engage; or, the linkage includes a push block and connecting rods disposed on both sides of the push block, the two ends of the connecting rods being hinged to the push block and the slider respectively, and the drive end of the driver is fixedly connected to the push block.

[0015] The above technical solution adopts the form of push block and slider inclined surface cooperation. The inclined surface transmission has strong load-bearing capacity and high rigidity. It is not easy to deform under the action of large forming force and can stably withstand the large load in the product forming process. It is suitable for forming scenarios with large force and high rigidity requirements. The push block is equipped with connecting rods on both sides and is respectively hinged to the slider. The connecting rod hinge transmission can realize a larger slider movement stroke. Under the premise of ensuring synchronous drive, a larger displacement can be obtained to meet the product needs of large stroke forming.

[0016] Furthermore, the mounting base is also provided with a stop member that blocks the movement path of the push block, and the stop member is movably mounted on the mounting base.

[0017] Through the above technical solution, the stop can directly block the movement range of the push block, thereby limiting the shaping displacement of the slider and minimizing the risk of product overpressure deformation or mold damage due to excessive drive stroke, thus ensuring stable and reliable shaping dimensions. Furthermore, the stop adopts a liftable structure, allowing for flexible adjustment of the lifting height to change the limit position of the push block according to the shaping stroke requirements of different products, adapting to the shaping requirements of battery trays of different specifications.

[0018] Furthermore, the mounting base is provided with a linear guide rail arranged along the slider shaping direction, and the slider is provided with a guide rail block that cooperates with the linear guide rail; or, the mounting base is provided with a guide block arranged along the slider shaping direction, and the slider is provided with a sliding groove that slides with the guide block.

[0019] The above technical solutions, which use linear guides and guide blocks, offer high guiding accuracy, low friction coefficient, and smoother movement. They are suitable for working conditions with high requirements for shaping position accuracy and provide better long-term stability. The combination of guide blocks and slides results in a simpler structure, larger load-bearing area, stronger rigidity, and easier processing and assembly. It is suitable for heavy-duty and harsh shaping scenarios.

[0020] Furthermore, the workbench is also equipped with a robotic arm and a drive device connected to the robotic arm. The robotic arm includes a main body and two robotic arms respectively located on both sides of the main body. Each of the two robotic arms is equipped with a clamping assembly.

[0021] The above technical solution enables both robotic arms to independently grip and position the product, allowing for more stable gripping and more precise alignment of the product before and after shaping.

[0022] Furthermore, the clamping assembly includes a connecting plate, a driving member, a first clamping part, and a second clamping part. The first clamping part is fixed on the robotic arm, and the second clamping part is hinged to the first clamping part. The driving end of the driving member is hinged to the second clamping part. The driving member and the connecting plate are fixedly connected as a whole, and the connecting plate and the robotic arm are detachably connected.

[0023] Through the above technical solution, the driving component and the connecting plate are fixedly connected as one unit, and the connecting plate is detachably connected to the robotic arm, so that the entire clamping assembly forms a modular structure. It can quickly adjust or change the installation position and posture of the clamping assembly on the robotic arm according to the product's external dimensions, without disassembling the robotic arm body and driving device, greatly shortening the changeover and adjustment time, and improving the adaptability speed of the forming mold to battery trays of different specifications.

[0055] The technical solution of the present invention will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0056] like Figures 1 to 23 As shown, the present invention provides a multi-structure shaping mold for shaping, including a worktable 10. The worktable 10 is provided with an upper mold 20, a lower mold 21, an inner mold mechanism 40, and an outer mold mechanism 41. The upper mold 20 and the lower mold 21 are slidably engaged by guide posts 11. The guide posts 11 are used to guide the upper mold 20 and the lower mold 21 to close. The upper mold 20 is driven to move closer to or away from the lower mold 21 by a hydraulic press 12. The lower mold 21 is provided with first mounting positions 13 for mounting the inner mold mechanism 40 and the outer mold mechanism 41, respectively. The inner mold mechanism 40 and the outer mold mechanism 41 each include a mounting base 42, a slider 43 slidably disposed on the mounting base 42, a driver 45 for driving the slider 43 to slide, and a shaping block 44 detachably mounted on the slider 43. The slider 43, the driver 45, and the mounting base 42 are connected as one unit. The mounting base 42 is detachably mounted on the first mounting position 13.

[0057] By designing the inner mold mechanism 40 and outer mold mechanism 41 as an independently detachable and replaceable structure, and combining them with a detachable shaping block 44, and pre-connecting the slider 43, driver 45, and mounting base 42 into a modular assembly, when different specifications of products 60 need to be replaced for shaping operations, it is not necessary to dismantle the entire workbench 10. The modular inner mold mechanism 40 or outer mold mechanism 41 can be replaced as a whole, or the shaping block 44 can be replaced individually. This simplifies the complex process of traditionally requiring the disassembly of multiple parts into a single operation of disassembling and assembling the mounting base 42 or the shaping block 44 for the first mounting position 13, significantly reducing the number of replacement steps, greatly shortening changeover waiting time, and improving the operating efficiency of the production line. At the same time, the same workbench 10 can be shared. Only inner mold mechanisms 40, outer mold mechanisms 41, and shaping blocks 44 of different specifications need to be stocked. By replacing modules such as inner mold mechanisms 40, outer mold mechanisms 41, and shaping blocks 44 of different specifications, the shaping needs of different positions and features of various shaping parts can be flexibly adapted. In specific implementation, for point features such as protrusions, pits, or pin holes on die-cast parts, a forming block 44 with a corresponding forming surface is selected, and precise point positioning is achieved through stamping; for linear features such as ribs, edges, or guide rails, a long strip-shaped or guide rail-shaped inner mold is used in conjunction with an outer mold to apply pressure along a straight trajectory to complete the straight positioning; for surface features such as planes, curved surfaces, or stepped surfaces, a large-area forming block 44 or a combination mold is used for surface positioning; and for the shaping requirements of the upper and lower end faces of thin-walled workpieces, the present invention uses an inner mold mechanism 40 and an outer mold mechanism 41 to simultaneously clamp the inner and outer sides of the thin-walled workpiece, providing stable support for the vertical thin-walled workpiece during the upper and lower shaping process, and preventing the thin-walled workpiece from bending and deforming due to force as much as possible, thereby solving the problem of easy deformation of the side walls when shaping the two ends of a vertical thin-walled workpiece. For die-cast parts 60 with complex structures, the inner and outer mold mechanisms 41 with different functions can be mixed and installed and work together to flexibly combine point, line and surface shaping units. This allows for the completion of all-round shaping requirements for complex die-cast parts in a single process or continuous workstation, which greatly reduces the material cost of mold production and also reduces the storage space occupied. At the same time, the coordinated setting of the upper mold 20, lower mold 21, inner mold mechanism 40 and outer mold mechanism 41 can perform multi-dimensional shaping of the die-cast part 60 from the top and bottom and inner and outer sides, realizing the overall shaping of the six sides of the part 60.

[0058] It should be noted that, to adapt to different workpiece placement postures, the upper mold 20 and lower mold 21 of the forming mold can be assembled inverted, without modifying the main structure of the mold or the transmission and guiding components, further improving the mold's versatility and adaptability to different working conditions. In this embodiment, the guide post 11 is the output shaft of the hydraulic press 12. Since the forming block 44 is detachable from the slider 43, by adjusting the installation position of the forming block 44 on the slider 43, specific positions of the workpiece can be flexibly shaped to meet the shaping needs of different workpieces.

[0059] Specifically, the shaping block 44 is fixedly installed on the slider 43. The relative position of the shaping block 44 and the slider 43 is stable, which can ensure the shaping dimension accuracy and repeatability accuracy, and meet the high-precision shaping requirements.

[0060] The shaping block 44 is provided with a shaping plane 441, which can perform more stable and uniform pressure correction on the planar areas of the product 60, ensuring consistent force on the shaping area as much as possible, eliminating dimensional deviations such as warping and deformation of the battery tray plane, and improving the flatness and geometric accuracy of the shaped surface. A shaping block 44 with a corresponding sized shaping plane 441 can be selected according to the size of the surface to be shaped on the product 60 to achieve a good shaping and bonding effect.

[0061] Furthermore, the slider 43 is provided with multiple second mounting positions 431 for mounting the shaping blocks 44. The multiple second mounting positions 431 are spaced apart. On the one hand, the second mounting position 431 can be flexibly selected to assemble the shaping blocks 44 according to the distribution of the shaping area, size and deformation correction requirements of the product 60, so as to realize the free combination and layout adjustment of the shaping points and meet the differentiated correction requirements of different parts of the same product 60 or different specifications of the product 60. On the other hand, the structure of multiple second mounting positions 431 spaced apart can adapt to the shaping contour and size of different models of products 60 by simply adjusting the assembly position of the shaping blocks 44 on the second mounting positions 431 without changing the slider 43 and the mounting base 42, thereby further improving the universality of the inner mold mechanism 40 and the outer mold mechanism 41.

[0062] It should be noted that, due to the large area of ​​the outer periphery of the product 60, the shaping block 44 and slider 43 of the outer mold mechanism 41 can also be an integral structure in other embodiments, in addition to the above-mentioned separate structure. This eliminates the need for the disassembly and assembly structure between the shaping block 44 and the slider 43, thereby improving the overall structural rigidity and load-bearing capacity. The entire slider 43 no longer has multiple second mounting positions 431, and its own surface is the shaping surface. This enables stable shaping of a large area of ​​the outer periphery of the product 60, ensuring the accuracy of the shaping surface, while simplifying assembly and improving operational stability.

[0063] To further simplify the structure, the inner mold mechanism 40 is provided with a pair of sliders 43. The inner mold mechanism 40 also includes a linkage 46 for simultaneously connecting the pair of sliders 43. The driving end of the driver 45 is connected to the linkage 46. The driver 45 drives the pair of sliders 43 to move towards each other or away from each other through the linkage 46. This eliminates the complex arrangement of configuring a separate driver 45 for each slider 43, greatly reducing the number of drivers 45 and greatly simplifying the overall structure of the inner mold mechanism 40. At the same time, using a single driver 45 in conjunction with the linkage 46 to achieve linkage of the two sliders 43 can ensure that the movement pace of the sliders 43 on both sides is completely consistent, and avoids shaping deviation caused by asynchronous driving as much as possible. This ensures the synchronicity and stability of the shaping operation and effectively improves the overall shaping efficiency.

[0064] Specifically, the linkage 46 includes a push block 461, which is fixedly connected to the drive end of the driver 45. The two sides of the push block 461 and the paired sliders 43 are respectively fitted with inclined surfaces. That is, the sidewalls of the push block 461 facing the two sliders 43 are provided with inclined guide surfaces 4611, and the opposite sidewalls of the two paired sliders 43 are machined with mating inclined surfaces 432 that are adapted to the inclined guide surfaces 4611 on both sides of the push block 461. When the drive end of the actuator 45 drives the push block 461 to move vertically, the inclined guide surface 4611 of the push block 461 and the mating inclined surface 432 of the slider 43 press against each other, converting the vertical linear thrust of the push block 461 into a horizontal component force of the sliders 43 on both sides. When the actuator 45 drives the push block 461 to rise, the mutual pressing of the inclined surfaces drives the sliders 43 on both sides to move in opposite directions and separate along the shaping direction. To achieve automatic reset of the sliders 43, an elastic element is provided between the two pairs of sliders 43. When the actuator 45 drives the push block 461 to fall downward, the pressing force of the inclined surfaces disappears, and the sliders 43 move towards each other and close together along the shaping direction under the elastic force of the elastic element, completing the reset action. The inclined surface transmission has a strong load-bearing capacity and high rigidity, and is not easily deformed under large shaping forces. It can stably withstand the large loads during the shaping process of the product 60, and is suitable for shaping scenarios with large shaping areas, large forces, and high rigidity requirements.

[0065] To make the slider 43 move more smoothly, the mounting base 42 is provided with a linear guide rail 421 arranged along the shaping direction of the slider 43, and the slider 43 is provided with a guide block 47 that cooperates with the linear guide rail 421. The linear guide rail 421 and the guide block 47 have high matching accuracy, low friction coefficient, and smoother movement, which is suitable for working conditions with high requirements for shaping position accuracy and has better long-term stability.

[0066] Of course, the guide structure of the outer mold mechanism 41 can also be replaced by the linear guide rail 421 and guide rail block 47 by the cooperation of guide rod 48 and bushing 49. Specifically, guide rod 48 can be set on slider 43 and bushing 49 can be set on mounting base 42. The slider 43 can be smoothly guided by the sliding cooperation of guide rod 48 and bushing 49. The structure is simple, the assembly is convenient, and it is suitable for the guidance needs under different working conditions.

[0067] To further improve the shaping effect, the mounting base 42 is also equipped with a stop 50. The stop 50 stops the movement path of the push block 461, which is used to more accurately limit the shaping displacement of the slider 43, and avoid excessive pressure deformation of the product 60 or damage to the mold due to excessive stroke of the driver 45, so as to maximize the stability and reliability of the shaping dimensions. The stop 50 is mounted on the mounting base 42 in a liftable manner. Specifically, the mounting base 42 is fixed with a Z-shaped fixing plate 501. A limit bolt 502 is threaded through and connected to the fixing plate. The limit bolt 502 is arranged vertically and located directly above the push block 461. By rotating the limit bolt 502, the distance between the bottom end of the limit bolt 502 and the top end of the push block 461 can be adjusted, thereby changing the upper limit position of the push block 461 and adjusting the shaping stroke of the slider 43. The shaping dimensions can be quickly adjusted according to the on-site process requirements, which is especially suitable for rapid shape change and shaping of battery trays of different specifications.

[0068] To enable the loading and unloading of product 60, the workbench 10 is also equipped with a robot arm 30 and a drive device connected to the robot arm 30. The drive device can be a rotary cylinder, a servo motor, or a multi-axis linkage module. The drive device can drive the robot arm 30 to extend into or move out of the shaping area of ​​the workbench 10, and can also drive the robot arm 30 to rotate around its own axis to realize the transfer and repositioning of product 60 between the loading / unloading station and the shaping station. The robot arm 30 includes a main body and two robotic arms 31 respectively located on both sides of the main body. Each robotic arm 31 is equipped with a clamping component 32. The clamping component 32 can be used independently, so that both robotic arms 31 can independently clamp and position product 60, enabling more stable gripping and more precise alignment of product 60 before and after shaping.

[0069] Specifically, the clamping assembly 32 includes a connecting plate 321, a driving member 322, a first clamping part 323, and a second clamping part 324. The driving member 322 may be a hydraulic cylinder. The first clamping part 323 is fixed on the robotic arm 31. The second clamping part 324 is hinged to the first clamping part 323. The driving end of the driving member 322 and the second clamping part 324 are hinged together. The driving member 322 and the connecting plate 321 are fixedly connected as a whole. The connecting plate 321 and the robotic arm 31 are detachably connected. The robotic arm 31 has multiple sets of mounting holes arranged along its length, and the connecting plate 321 has corresponding matching connecting holes 325. By using fasteners such as screws and bolts to pass through the mounting holes and connecting holes 325 at different positions, the mounting position and posture of the connecting plate 321 on the robotic arm 31 can be adjusted, so that the entire clamping assembly 32 forms a modular structure. According to the external dimensions of the product 60, the mounting position and posture of the clamping assembly 32 on the robotic arm 31 can be quickly adjusted or changed without disassembling the robotic arm 31 body and drive device, which greatly shortens the changeover and adjustment time and improves the adaptation speed of the shaping device to battery trays of different specifications.

[0070] It should be noted that the lower mold 21 is provided with multiple first mounting positions 13, which can flexibly install inner mold mechanisms 40 and outer mold mechanisms 41 with different structures and specifications according to the shaping requirements of different workpieces. There is no need to modify the lower mold 21 body, which can quickly adapt to the shaping requirements of various models of products 60, effectively improving the versatility and changeover efficiency of the mold.

[0071] It should be noted that the multi-structure forming mold is suitable for forming die-cast products 60 at different temperatures, such as normal temperature or high temperature environments. Because this forming mold adopts a rigid and reliable transmission and guiding structure, the overall structure has high strength and strong resistance to deformation, and the various moving parts cooperate stably, maintaining good motion accuracy and structural stability under both normal temperature and high temperature die-casting forming conditions.

[0072] When using it, first select the appropriate inner mold mechanism 40 and outer mold mechanism 41 to complete the mold assembly according to the specifications and structure of the product 60 to be shaped. After one side of product 60 is shaped, the robot arm 30 extends into the shaping mold, removes the shaped product 60, exits the mold, and rotates product 60 180° so that the other side of product 60, which is not shaped, faces the shaping station. Then, product 60 is placed back into the shaping mold. After product 60 is in place, the robot arm 30 exits the shaping area of ​​the shaping mold. Subsequently, the hydraulic press 12 drives the upper mold 20 to descend and close with the lower mold 21 to flatten and shape the upper and lower surfaces of product 60. At the same time, the left and right sides of product 60 are respectively opened outward by the corresponding inner mold mechanism 40 and opened inward by the outer mold mechanism 41 to complete the flattening and shaping of the left and right sides of product 60. After the overall shaping of product 60 is completed, the inner mold mechanism 40 and the outer mold mechanism 41 are reset, the upper mold 20 is moved upward to reset, and the robot arm 30 re-enters the shaping area to remove the shaped product 60.

[0073] It should be noted that when only the inner side of the product 60 is shaped, the outer mold mechanism 41 is activated first, so that the shaping block 44 of the outer mold mechanism 41 abuts against the outer side of the product 60 and maintains the current state. Then the inner mold mechanism 40 is activated, and the shaping block 44 of the inner mold mechanism 40 shapes the inner side of the product 60 outward.

[0074] When only the outer side of product 60 is shaped, the inner mold mechanism 40 is activated first, so that the shaping block 44 of the inner mold mechanism 40 abuts against the inner side of product 60 and maintains the current state. Then the outer mold mechanism 41 is activated, and the shaping block 44 of the outer mold mechanism 41 shapes the outer side of product 60 inward.

[0075] When shaping both the inner and outer sides of product 60 simultaneously, the inner mold mechanism 40 and the outer mold mechanism 41 are activated at the same time.

[0076] It should be noted that the lower mold 21 may also be provided with a limiting post 22 to limit the downward stroke of the upper mold 20, so as to avoid the product 60 from being over-compressed or damaged in the height direction due to excessive downward pressure, and to ensure that the forming dimensions are stable and reliable.

[0077] Understandably, in other embodiments, the shaping block 44 can also be floatingly mounted on the slider 43. For example, the shaping block 44 and the slider 43 are connected by an elastic connector or a guide fit structure, so that the shaping block 44 can float relative to the slider 43. The shaping block 44 can adaptively adjust its posture and position within a certain range, which can adapt to the surface of products 60 of different shapes and sizes. It can also compensate for the dimensional deviation of the product 60 itself, the mold assembly error, and the force offset during the shaping process, so as to avoid rigid extrusion causing local overpressure, cracking, or dimensional deviation of the product 60, thereby improving the shaping effect. At the same time, the two installation methods can be switched as needed according to the actual production conditions, further enhancing the adaptability and flexibility of the multi-structure shaping mold to products 60 of different specifications and structures.

[0078] Understandably, in other embodiments, the shaping block 44 is provided with a shaping surface 442, such as a concave or convex surface, which can perform conformal pressure correction on the area with curved features on the product 60, so that the shaping force is evenly distributed along the curved surface, and the deformation and dimensional deviation of the curved part of the battery tray can be eliminated as much as possible, and the contour accuracy and positional accuracy of the shaped surface can be guaranteed as much as possible. The shaping block 44 with an adapted shaping surface 442 can be selected according to the curvature and contour shape of the curved surface 442 to be shaped on the product 60.

[0079] Understandably, in other embodiments, the linkage 46 includes a push block 461 and connecting rods 462 disposed on both sides of the push block 461. Two parallel connecting rods 462 can be disposed on each side to form a multi-link 462 transmission structure. The multi-link 462 transmission structure has a large opening and closing angle, which can ensure that the force of the driver 45 is transmitted to the slider 43 to the product being shaped, resulting in high energy efficiency and further improving the stability of force application. The two ends of the connecting rods 462 are hinged to the push block 461 and the slider 43, respectively, and the driving end of the driver 45 is fixedly connected to the push block 461. When the driver 45 drives the push block 461 to move, the connecting rods 462 gradually change from an inclined state to a horizontal state, thereby synchronously pushing the sliders 43 on both sides to move in opposite directions or in opposite directions. When the driver 45 drives the push block 461 to reset in the opposite direction, the connecting rods 462 turn back from a horizontal state to an inclined state, driving the sliders 43 to reset synchronously. This type of articulated transmission 462 allows for a larger travel of the slider 43. While ensuring synchronous drive by a single driver 45, it can achieve a larger displacement, meeting the needs of products 60 requiring large-stroke shaping. It is suitable for multi-area shaping. Since the sliders 43 on both sides adopt a synchronous drive method, the force on both sides of the product 60 can be evenly distributed during the shaping process, avoiding deformation or displacement caused by uneven force on one side as much as possible, thereby ensuring the consistency of the shaping effect and improving the product processing accuracy.

[0080] Understandably, in other embodiments, the mounting base 42 is provided with a guide block 422 arranged along the shaping direction of the slider 43, and the slider 43 is provided with a groove 433 that slides and engages with the guide block 422. The structure is simpler, the bearing area is larger, the rigidity is stronger, the processing and assembly are easier, and it is suitable for heavy-duty and harsh shaping scenarios.

[0081] Among them, the internal mold mechanism 40 is mainly divided into three structural forms: such as Figures 6 to 8 The first type uses a pusher block 461 with an inclined surface for pushing, and the shaping block 44 is fixedly installed and has a shaping plane 441, which is suitable for large-area shaping. The slider 43 moves quickly in translation. Figures 9 to 12 The second type uses a connecting rod 462 for pushing, and the shaping block 44 is fixedly installed and has a shaping plane 441, which is suitable for simultaneous shaping in multiple areas; such as Figures 13 to 15The third type uses a connecting rod 462 for pushing, and the shaping block 44 is floating and has a shaping curved surface 442, which is suitable for shaping the local curved surface of product 60.

[0082] The external mold mechanism 41 is mainly divided into two structural forms: such as Figure 17 and Figure 18 The first type features a single-piece structure where the shaping block 44 and slider 43 form a shaping plane 441, suitable for planar shaping; for example... Figure 19 and Figure 20 The second type is a split structure of shaping block 44 and slider 43. The shaping block 44 is floating and has a shaping surface 442, which is suitable for local surface shaping.

[0083] It is understood that in other embodiments, such as Figure 24 As shown, the inclined surface 432 is divided into three segments from bottom to top: the first segment 4321 is an inclined surface, the second segment 4322 is a vertical plane, and the third segment 4323 is an inclined surface. The second segment 4322 smoothly connects the first segment 4321 and the third segment 4323. The shaping block 44 of the inner mold mechanism 40 forms three working positions according to the contact state between the push block 461 and the above three segments: when the push block 461 is located in the first segment 4321, the shaping block 44 is in a clearance position, away from the product 60 for feeding; when the push block 461 moves to the second segment 4322, the shaping block 44 is in a waiting position. At this time, due to the guiding characteristics of the vertical plane, the shaping block 44 abuts against the product 60 and remains radially stationary; when the push block 461 enters the third segment 4323, the shaping block 44 reaches the shaping position and applies force to form the product. The shaping block 44 of the outer mold mechanism 41 is also equipped with corresponding avoidance and shaping positions to cooperate with the inner mold movement.

[0084] When product 60 needs to be simultaneously shaped on both the inner and outer sides, the system first activates the inner mold mechanism 40, driving the shaping block 44 to move upward from the avoidance position. Once the push block 461 enters the second stage 4322, it is in a waiting position, and the inner mold shaping block 44 is tightly pressed against product 60. The characteristics of the second stage 4322 are used to lock the position of product 60 and prevent it from shifting. During this time window when the inner mold remains stationary, the system simultaneously activates the outer mold mechanism 41, driving its shaping block 44 to move quickly from the avoidance position to the surface of product 60. This effectively compensates for the action response delay of the outer mold mechanism 41. When the shaping block of the outer mold mechanism 41 presses against product 60, the inner mold push block 461 continues to move upward into the third stage 4323. The inner mold mechanism 40 and the outer mold mechanism 41 then apply force simultaneously to achieve simultaneous shaping of both the inner and outer sides of product 60.

[0085] When it is necessary to shape the inner side of product 60, the outer mold mechanism 41 is activated first, so that the shaping block 44 of the outer mold mechanism 41 abuts against the outer side of product 60 and remains in the current state. Then, the inner mold mechanism 40 is activated, and the shaping block 44 of the inner mold mechanism 40 shapes the inner side of product 60 outward. Conversely, when it is necessary to shape the outer side of product 60, the inner mold mechanism 40 is activated first, so that the push block 461 enters the second section 4322, that is, it is in the waiting position and remains there. The inner mold shaping block 44 is then in close contact with product 60. Then, the outer mold mechanism 41 is activated to shape the outer side of product 60.

[0086] It should be noted that the products 60 applicable to this forming mold include aluminum alloy die-cast parts for new energy battery trays, but are not limited to this. It is also compatible with the forming operations of other similar aluminum alloy die-cast parts and structural parts, and the range of applicable products 60 is quite wide.

[0087] In addition to the preferred embodiments described above, the present invention has other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
