[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Reference Figures 1 to 7As shown, an embodiment of the present invention provides an automotive sheet metal production mold, comprising an upper mold base 100, a lower mold base 200, and a supporting component 300.

[0035] Reference Figure 1 , Figure 2 and Figure 3 As shown, the automotive sheet metal production mold can be used in conjunction with an external opening and closing drive device. Under the driving action of the external opening and closing drive device, the upper mold base 100 can move closer to or further away from the lower mold base 200, so as to realize the mold closing or mold opening of the upper mold base 100 and the lower mold base 200. The sheet metal can be placed between the upper mold base 100 and the lower mold base 200, and the processing and forming can be realized under the mold closing action of the upper mold base 100 and the lower mold base 200.

[0036] Reference Figure 2 , Figure 4 and Figure 5 As shown, specifically, the automotive sheet metal production mold also includes a support component 300. Two support components 300 are provided, and both support components 300 are connected to the lower mold base 200 and are located at the end of the lower mold base 200 along the sheet metal conveying direction. Taking the sheet metal being conveyed from the left end to the right end of the lower mold base 200 as an example, the support component 300 is connected to the right end of the lower mold base 200.

[0037] Reference Figure 2 , Figure 4 and Figure 5 As shown, the supporting member 300 has an idle state and a processing state. In the idle state, the supporting member 300 is inwardly attached to the side wall of the lower mold base 200 to eliminate the support or positioning of the sheet metal by the supporting member 300, which is suitable for scenarios that reduce processing stations. In the processing state, the supporting member 300 is extended outward relative to the lower mold base 200, and multiple supporting members 300 jointly define an extended processing station. The extended processing station is used to support the sheet metal, which is suitable for scenarios that increase processing stations.

[0038] Reference Figure 2 , Figure 4 and Figure 5As shown, when the process requires adding a new step, the automotive sheet metal production mold can switch the supporting component 300 to the processing state. In the processing state, the supporting component 300 expands outward relative to the lower mold base 200. Multiple supporting components 300 together define the extension processing station, which can be used to support the sheet metal. The supporting component 300 is located at the end of the lower mold base 200 along the sheet metal conveying direction. That is, through the movement of the supporting component 300 relative to the lower mold base 200, the automotive sheet metal production mold adds an extension processing station. When the sheet metal moves to the extension processing station, the sheet metal located at the extension processing station can be processed in conjunction with the external processing component. That is, the sheet metal is processed using an improved processing technology without the need to redesign and produce the mold. This is beneficial to improving the compatibility of the automotive sheet metal production mold with different processing technologies, making the automotive sheet metal production mold more economical.

[0039] Reference Figure 2 , Figure 4 and Figure 5 As shown, if the sheet metal is not required to be processed using an external processing station or if the number of processing steps needs to be reduced, the automotive sheet metal production mold can switch the load-bearing component 300 to an idle state. In the idle state, the load-bearing component 300 is inwardly attached to the side wall of the lower mold base 200, thereby eliminating the supporting effect of the load-bearing component 300 on the sheet metal. This helps to reduce the space occupied by the automotive sheet metal production mold and improve the compatibility of the automotive sheet metal production mold.

[0040] Reference Figure 2 , Figure 4 and Figure 5 As shown, traditional production molds have limited applicability, and if the processing technology needs to be changed, it is generally necessary to redesign and reproduce the corresponding mold. However, the automotive sheet metal production mold provided in this embodiment of the utility model can reduce or increase an extension processing station by fitting or unfolding the supporting component 300 relative to the lower mold base 200, so as to adapt to changes in processing technology and improve the compatibility and economy of the automotive sheet metal production mold.

[0041] It should be understood that in some other embodiments, three or more load-bearing members 300 are provided, and the three or more load-bearing members 300 can achieve stable support and positioning of the sheet metal in the processing state.

[0042] It should be understood that in some other embodiments, the support member 300 is connected to the left end of the lower mold base 200, that is, the support member 300 is located at the starting end of the sheet metal along the conveying direction of the lower mold base 200, and the extended processing station can be used to perform preliminary processing on the sheet metal before it moves to below the upper mold base 100.

[0043] Reference Figure 2 , Figure 4 and Figure 5As shown, it can be understood that in this embodiment, the load-bearing component 300 includes a frame 310 and a plurality of support columns 320 connected to the upper end of the frame 310. The two ends of the support columns 320 are arranged in the vertical direction, and the plurality of support columns 320 are arranged at intervals along the horizontal plane.

[0044] Reference Figure 2 , Figure 4 and Figure 5 As shown, specifically, the load-bearing component 300 of the automotive sheet metal production mold includes three support columns 320, which improve the stability of the load-bearing component 300 in supporting the sheet metal through multi-point support. The upper end of the support column 320 is provided with a contraction section, the external dimensions of which gradually decrease from bottom to top. The support column 320 can be used to support the sheet metal, and the contraction section at the upper end of the support column 320 can be used to achieve the initial positioning of the sheet metal.

[0045] It should be understood that in some other embodiments, two or more support columns 320 are provided to improve the support stability of the load-bearing member 300 on the sheet metal through multi-point support.

[0046] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that in this embodiment, the automotive sheet metal production mold also includes multiple threaded connectors. The frame 310 is provided with multiple screw holes. The lower end of the support column 320 is connected to the mounting plate 330. The mounting plate 330 is provided with a strip hole 331. The strip hole 331 is opposite to a screw hole and connected to a threaded connector. The threaded connector passes through the strip hole 331 and is threadedly connected to the screw hole.

[0047] Reference Figure 2 , Figure 4 and Figure 5 As shown, during assembly, the user can fit the mounting plate 330 against the frame 310, aligning the strip hole 331 with the screw hole. Then, the threaded connector is inserted into the strip hole 331 and threadedly connected to the screw hole. By adjusting the position of the threaded connector within the strip hole 331, the user can adjust the relative position of the mounting plate 330 and the frame 310, thereby adjusting the spacing between the multiple support columns 320 to adapt to sheet metal of different specifications, thus improving the compatibility between the support columns 320 and the sheet metal.

[0048] Reference Figure 2 , Figure 4 and Figure 5 As shown, after adjustment, the user can tighten the threaded connector to press the mounting plate 330 tightly, thereby fixing the relative position of the mounting plate 330 and the frame 310.

[0049] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the load-bearing component 300 also includes a positioning block 340, which is connected to the upper end of the frame 310. Multiple support columns 320 are arranged around the positioning block 340, and the upper end of the positioning block 340 has a positioning surface 341 that is adapted to the sheet metal surface.

[0050] Reference Figure 2 , Figure 4 and Figure 5 As shown, under the conveying action of the external conveying mechanism, the sheet metal moves to the external processing station, so that the lower end of the sheet metal abuts against the support column 320, and the lower surface of the sheet metal fits against the shaping surface of the positioning block 340. The shaping surface can be designed according to the surface shape of the sheet metal so that the shaping surface matches the surface shape of the sheet metal. Through the fitting of the shaping surface and the surface of the sheet metal, the positioning of the sheet metal is realized, which helps to improve the positioning accuracy and processing accuracy of the sheet metal.

[0051] Reference Figure 2 , Figure 4 and Figure 5 As shown, it is understood that the sheet metal is provided with positioning holes. The automotive sheet metal production mold also includes positioning pins 350. Positioning pins 350 are connected to the upper end of positioning block 340, that is, positioning pins 350 are connected to positioning surface 341. Positioning pins 350 have a tip that gradually narrows from bottom to top. The setting of the tip makes it easy for positioning pins 350 and positioning holes to fit together and be inserted.

[0052] Reference Figure 2 , Figure 4 and Figure 5 As shown, under the conveying action of the peripheral conveying mechanism, the sheet metal moves to the extension processing station, allowing the lower end of the sheet metal to abut against the support column 320, and the lower surface of the sheet metal to fit into the shaping surface of the positioning block 340. The positioning pin 350 passes through the positioning hole of the sheet metal. Through the mutual limiting of the outer and inner circumferential surfaces of the positioning hole, accurate positioning of the sheet metal is achieved, which helps improve the positioning accuracy and processing accuracy of the sheet metal. After the sheet metal is processed at the extension processing station, the peripheral conveying mechanism can lift the sheet metal upwards, separating it from the positioning block 340 and causing the positioning pin 350 to exit the positioning hole, thus avoiding the problem of the positioning pin 350 obstructing the movement of the sheet metal.

[0053] Reference Figure 2 , Figure 4 and Figure 5As shown, it can be understood that the side wall of the lower mold base 200 is connected to the mounting base 400, the mounting base 400 is provided with an upward-facing square hole 410, the lower end of the frame 310 is connected to a square column 360, the two ends of the square column 360 are arranged in the vertical direction, the square column 360 can enter and exit the square hole 410, and the bearing member 300 is configured to be able to rotate at a right angle relative to the lower mold base 200 to switch between idle state and processing state.

[0054] Reference Figure 2 , Figure 4 and Figure 5 As shown, when the user needs to switch the load-bearing component 300 from the idle state to the processing state, the user can raise the load-bearing component 300 upwards, so that the square column 360 passes through the square hole 410 upwards, thereby eliminating the obstruction of the square hole 410 to the rotation of the square column 360. Then, the user can rotate the square column 360 90 degrees in the positive direction around the vertically extending axis, so that the support column 320 and the positioning block 340 unfold outwards relative to the side wall of the lower mold base 200. After rotating into place, the user can insert the square column 360 downwards into the square hole 410. Through the mutual abutment between the square column 360 and the square hole 410, the rotation of the load-bearing component 300 is restricted, so that the load-bearing component 300 is switched to the processing state.

[0055] Reference Figure 2 , Figure 4 and Figure 5 As shown, when the user needs to switch the load-bearing component 300 from the processing state to the idle state, the user can raise the load-bearing component 300 so that the square column 360 passes through the square hole 410, thereby eliminating the obstruction of the square hole 410 to the rotation of the square column 360. Then, the user can rotate the square column 360 90 degrees in the opposite direction around the vertically extending axis, so that the support column 320 and the positioning block 340 fit inward relative to the side wall of the lower mold base 200. After rotating into place, the user can insert the square column 360 downward into the square hole 410. Through the mutual abutment between the square column 360 and the square hole 410, the rotation of the load-bearing component 300 is restricted, so that the load-bearing component 300 is switched to the idle state.

[0056] Reference Figure 2 , Figure 4 and Figure 5 As shown, the square hole 410 is designed to extend vertically through the interior and exterior. The mounting post is also equipped with an adjusting screw hole. The automotive sheet metal production mold also includes an adjusting rod with a threaded section that is threadedly connected to the adjusting screw hole. The square post 360 passes through the square hole 410. The user can adjust the installation height of the square post 360 relative to the mounting base 400, and then tighten the adjusting rod. Through the cooperation of the threaded section and the adjusting screw hole, the adjusting rod is inserted into the square hole 410 and abuts against the side wall of the square post 360 to lock the installation height of the square post 360 and the mounting base 400.

[0057] Reference Figure 2, Figure 4 and Figure 5 As shown, the automotive sheet metal production mold can be adapted to different specifications of sheet metal by adjusting the installation height of the load-bearing component 300 and the lower mold base 200, thereby improving its applicability to different sheet metals, compatibility, and economy.

[0058] Reference Figure 2 , Figure 4 and Figure 5 As shown, it is understandable that, in order to further improve the stability of the load-bearing components 300 in the processing state, the automotive sheet metal production mold also includes a connecting rod 500 and multiple screws. In the processing state, the ends of the multiple load-bearing components 300 away from the lower mold base 200 are all connected to the connecting rod 500.

[0059] Reference Figure 2 , Figure 4 and Figure 5 As shown, specifically, in the processing state, the end of the frame 310 of the load-bearing component 300 away from the lower mold base 200 is provided with a threaded connection hole, and the connecting rod 500 is provided with multiple through holes. The threaded connection hole is opposite to one of the through holes and connected to a screw. During assembly, the user can fit the connecting rod 500 against the end of the frame 310 away from the lower mold base 200, so that the through hole is opposite to the threaded connection hole, and insert the screw into the through hole and thread it into the threaded connection hole, so that the multiple load-bearing components 300 are fixed as one, making the position and connection effect of the multiple load-bearing components 300 more stable and reliable.

[0060] Reference Figure 1 , Figure 6 and Figure 7 As shown, it is understandable that the automotive sheet metal production mold has multiple processing stations, which can realize multiple processing steps of sheet metal, which helps to reduce the number of supporting molds and can effectively reduce the number of components such as guide pillars, thereby reducing the design and manufacturing costs of the mold.

[0061] Reference Figure 1 , Figure 6 and Figure 7 As shown, specifically, the lower mold base 200 is provided with a stretching protrusion 210, and the upper mold base 100 is provided with a stretching groove 110 that is opposite to and adapted to the stretching protrusion 210. Under the conveying action of the external conveying mechanism, when the sheet metal moves between the stretching protrusion 210 and the stretching groove 110, the upper mold base 100 and the lower mold base 200 close, so that the sheet metal is stretched to form a shape adapted to the stretching protrusion 210 and the stretching groove 110, thereby forming the preliminary shape of the sheet metal.

[0062] Reference Figure 1 , Figure 6 and Figure 7As shown, specifically, the lower die holder 200 is provided with a first punching protrusion 220, and the upper die holder 100 is provided with a first punching groove 120 that is opposite to and adapted to the first punching protrusion 220. Under the conveying action of the external conveying mechanism, when the sheet metal moves between the first punching protrusion 220 and the first punching groove 120, the upper die holder 100 and the lower die holder 200 close. Through the engagement of the first punching protrusion 220 and the second punching groove 130, the edge of the sheet metal can be punched, so that the sheet metal is formed according to a preset shape.

[0063] Reference Figure 1 , Figure 6 and Figure 7 As shown, considering that a single punching operation is insufficient to complete the forming of the sheet metal edge, the lower die holder 200 is also provided with a second punching protrusion 230. Correspondingly, the upper die holder 100 is provided with a second punching groove 130 that is opposite to and fits the second punching protrusion 230. Under the conveying action of the external conveying mechanism, when the sheet metal moves between the second punching protrusion 230 and the second punching groove 130, the upper die holder 100 and the lower die holder 200 close. Through the engagement of the second punching protrusion 230 and the second punching groove 130, a secondary punching of the sheet metal edge can be achieved, so that the sheet metal is formed according to a preset shape.

[0064] Reference Figure 1 , Figure 6 and Figure 7 As shown, specifically, the automotive sheet metal production mold also includes a punch 250. The lower mold base 200 is provided with a punching protrusion 240, and the punch 250 is adjacent to the punching protrusion 240 for punching the side wall of the sheet metal located at the punching protrusion 240. The upper mold base 100 is provided with a punching groove 140 that is opposite to and adapted to the punching protrusion 240. Under the conveying action of the external conveying mechanism, when the sheet metal moves between the punching protrusion 240 and the punching groove 140, the upper mold base 100 and the lower mold base 200 close, so that the sheet metal is clamped between the punching protrusion 240 and the punching groove 140 to fix the sheet metal. The punch 250 can extend relative to the sheet metal to achieve piercing and punching of the sheet metal.

[0065] Reference Figure 1 , Figure 6 and Figure 7As shown, specifically, the stretching protrusion 210, the first punching protrusion 220, the second punching protrusion 230, and the punching protrusion 240 are arranged sequentially from left to right on the upper surface of the lower die holder 200. Correspondingly, the stretching groove 110, the first punching groove 120, the second punching groove 130, and the punching groove 140 are arranged sequentially from left to right on the lower surface of the upper die holder 100. That is, this automotive sheet metal production die can realize stretching, primary punching, secondary punching, and punching of sheet metal, enabling multiple processing of sheet metal. This helps reduce the number of supporting processing dies, improves sheet metal production efficiency, and reduces the manufacturing cost of production equipment using this automotive sheet metal production die.

[0066] Reference Figure 1 , Figure 6 and Figure 7 As shown, it should be noted that the punch 250 includes a punch and a linear drive mechanism. The linear drive mechanism can be a pneumatic push rod, a hydraulic push rod, or an electric push rod, etc. The linear drive mechanism drives the punch to approach the sheet metal located on the punching protrusion 240, so that the punch passes through the sheet metal, thereby completing the punching of the sheet metal. The linear drive mechanism drives the punch away from the sheet metal located on the punching protrusion 240, so that the punch exits the sheet metal, in order to complete the subsequent conveying of the sheet metal.
