[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A precision stamping die for a liquid-cooled plate includes a press body 1, an upper die 2 and a lower die 3 are bolted inside the press body 1, a buffer assembly 4 is fixedly connected to the surfaces of the upper die 2 and the lower die 3, and a lubrication assembly 5 is fixedly connected to the surface of the press body 1.

[0027] The buffer assembly 4 includes a connecting frame 401, a protective pad 402 is movably connected to the bottom of the connecting frame 401, a connecting plate 403 is fixedly connected to the bottom of the protective pad 402, a plurality of springs 404 are fixedly connected to the bottom of the connecting plate 403, a connecting frame 405 is fixedly connected to the bottom of the plurality of springs 404, the connecting frame 405 is fixedly connected to the surface of the lower mold 3, and the connecting frame 401 is bolted to the surface of the upper mold 2.

[0028] In this embodiment: the press body 1 serves as the core support and power output base, used to fix components such as the upper die 2 and lower die 3, while providing the high-precision pressure required for stamping. It drives the upper die 2 to move up and down to achieve plastic deformation of the metal sheet, acting as the power source and mounting reference for the liquid-cooled plate stamping. The upper die 2 and lower die 3 are fixed to the bottom of the press body 1, with internal concave cavities required for liquid-cooled plate forming. Under the control of the press body 1, the sheet metal is stamped and formed. A buffer assembly 4 buffers the impact force generated when the upper die 2 and lower die 3 come into contact. By setting the lubrication component 5, the auxiliary rod of the press body 1 can be lubricated. By setting the connecting frame 401, the upper mold 2 and the buffer component 4 are connected, and the pressure of the upper mold 2 is transmitted to the subsequent buffer component. By setting the protective pad 402, it is fixedly connected to the top of the connecting frame 405 and contacts the connecting frame 401. By setting the connecting frame 405, several springs 404 are supported. By setting several springs 404, the core buffer component absorbs the impact force when the upper and lower molds 3 are attached through its own compression deformation, reducing the wear of the upper mold 2 and the lower mold 3 at the moment of contact.

[0029] Specifically, such as Figure 3 As shown, the lubrication assembly 5 includes a bolt plate 501, the surface of which has a mounting hole 502, and a round sleeve 503 is fixedly connected to the inner wall of the mounting hole 502.

[0030] Specifically, such as Figure 3 As shown, the inside of the circular sleeve 503 is provided with a cavity 504, and a coating sleeve 505 is fixedly connected inside the cavity 504. The coating sleeve 505 is made of oil-absorbing and lubricating rubber.

[0031] Specifically, such as Figure 3 As shown, a scraper sleeve 506 is fixedly connected to the top of the circular sleeve 503. The scraper sleeve 506 is made of stainless steel. The scraper sleeve 506 and the coating sleeve 505 are movably connected to the surface of the press body 1.

[0032] In this embodiment: by setting a bolt plate 501, it is bolted to the top of the upper mold 2 by screws. By setting a mounting hole 502, a mounting space can be reserved for the round sleeve 503. By setting a round sleeve 503, a cavity 504 and a coating sleeve 505, the cavity 504 inside the round sleeve 503 stores the lubricant. Then, the coating sleeve 505 coats the auxiliary rod of the press body 1 with the lubricant. By setting a scraper sleeve 506, the surface of the auxiliary rod can be cleaned of impurities.

[0033] Specifically, such as Figure 3 As shown, the top of the circular sleeve 503 is connected to the filling tube 6, and the inside of the filling tube 6 is fitted with a sealing cap 7, which is made of plastic.

[0034] Specifically, such as Figure 5 As shown, auxiliary plates 8 are fixedly connected to the left and right sides of the lower mold 3, and auxiliary grooves 9 that cooperate with the auxiliary plates 8 are opened on the left and right sides of the inner walls of the protective pad 402 and the connecting plate 403.

[0035] In this embodiment: by setting the injection pipe 6, lubricant can be injected into the inside of the sleeve 503; by setting the sealing cap 7, the injection pipe 6 can be sealed; by setting the auxiliary plate 8 and the auxiliary groove 9, the auxiliary plate 8 and the auxiliary groove 9 work together to provide guidance for the up and down movement of the buffer assembly 4, prevent the buffer assembly 4 from shifting, and ensure that the upper mold 2 and the lower mold 3 fit precisely.

[0036] Specifically, such as Figure 4 As shown, two first magnet blocks 10 are fixedly connected inside the press body 1. The bottom of each of the two first magnet blocks 10 is magnetically attracted to a second magnet block 11. The bottom of each of the two second magnet blocks 11 is fixedly connected to a scraper frame 12.

[0037] Specifically, such as Figure 4 As shown, grooves 13 are provided on the left and right sides of the two scraper frames 12. A first clamp 14 and a second clamp 15 are engaged inside the two grooves 13. A splicing groove 16 is provided on the right side of the first clamp 14. A splicing block 17 that works with the splicing groove 16 is fixedly connected to the left side of the second clamp 15.

[0038] In this embodiment: two first magnet blocks 10 are fixed inside the press body 1 and connected to the second magnet block 11 by magnetic attraction, which facilitates the installation and disassembly of the scraper frame 12 and ensures the stability of the scraper frame 12 during operation. Two second magnet blocks 11 are fixed on the top of the scraper frame 12 and magnetically cooperate with the first magnet blocks 10 to achieve quick connection between the scraper frame 12 and the press body 1, making it easy for operators to disassemble and assemble the scraper frame 12 as needed. The scraper frame 12 is used to clean the impurities adsorbed on the surface of the press's own telescopic rod. The groove 13 provides an installation position for the first clamp 14 and the second clamp 15. The first clamp 14, the second clamp 15, the splicing block 17, and the splicing groove 16 are used to connect the first clamp 14 and the second clamp 15 through the splicing block 17 and the splicing groove 16, respectively, to limit the position of the two scraper frames 12.

[0039] Working principle: When this precision stamping die for liquid-cooled plates is working, the metal sheet to be processed is first placed into the concave cavity of the lower die 3 to prepare for stamping. Then, the press body 1 is started, driving the upper die 2 to move downward. The structure at the bottom of the upper die 2 applies high-precision pressure to the metal sheet, causing the sheet to undergo controllable plastic deformation under the joint constraint of the cavities of the upper die 2 and the lower die 3, gradually forming the required outer contour and internal flow channels of the liquid-cooled plate. As the upper die 2 moves downward and approaches and fits closer to the lower die 3, the surface of the upper die 2... The buffer assembly 4 operates synchronously. The connecting frame 401 moves down with the upper mold 2 and contacts the protective pad 402. The protective pad 402 initially buffers the impact. Then the impact force is transmitted to the connecting plate 403, causing the connecting plate 403 to squeeze the spring 404 at the bottom. The spring 404 further absorbs the impact force through compression deformation, avoiding direct hard contact between the upper mold 2 and the lower mold 3 and causing wear. At the same time, the auxiliary grooves 9 on the inner walls of the protective pad 402 and the connecting plate 403 slide along the auxiliary plates 8 on both sides of the lower mold 3 to ensure that the buffer assembly 4 moves smoothly without deviation.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
