[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0020] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an embodiment provided by the present invention: a stamping die with a discharging structure, including an upper die holder 1 and a lower die holder 2. The bottom of the upper die holder 1 is fixedly connected with a punch fixing plate 3, and the top of the punch fixing plate 3 is connected with a punch 4 The top of the lower die holder 2 is connected with a die fixing plate 5, the top of the die fixing plate 5 is connected with a die 6, and the punch 4 is adapted to the die 6 The top of the lower die holder 2 is connected with a die pushing component, and the die pushing component is used to push the stamping die located in the die 6 out of the die 6 after stamping The die pushing component includes a stamping die protection main body 7 connected to the top of the lower die holder 2. One side wall of the stamping die protection main body 7 is connected with a second hydraulic rod 8, and one end of the second hydraulic rod 8 is connected with a discharging plate 9

[0022] Furthermore, the stamping die of the present invention provides support for the core operation with a stable structure. The upper die holder 1 is an upper key component, and its bottom is combined with the punch fixing plate 3 through a firmly fixed connection method to ensure that the punch fixing plate 3 will not be displaced during the stamping process, thereby ensuring the stable operation of the punch 4.

[0023] The punch 4 is installed on the top of the punch fixing plate 3. During stamping, it will move downward with the upper die base 1, and cooperate with the lower die base 2 to complete the stamping task. The top of the lower die base 2 is connected to the die fixing plate 5 and the die 6 in sequence. The die fixing plate 5 plays a role in stabilizing the support of the die 6, so that the die 6 remains stable when subjected to stamping pressure. The punch 4 and the die 6 are precisely matched, and the matching accuracy of the two directly affects the forming quality of the stamped parts. When the mold is working, the upper die base 1 drives the punch 4 downward, and stamps the material placed therebetween with the die 6 to complete the shaping process.

[0024] After the stamping is completed, the mold ejection assembly begins to work. The stamping mold protection body 7 connected to the top of the lower mold base 2 is not only a protective barrier for the internal structure of the mold to prevent external debris from entering and affecting the normal operation of the mold, but also carries important discharge functional components. On one side wall of the stamping mold protection body 7, a hydraulic rod 2 8 is connected. The hydraulic rod 2 8 has precise telescopic control capabilities. When receiving a discharge instruction, the hydraulic rod 2 8 extends to push the discharge plate 9 connected to it to move toward the direction of the die 6.

[0025] See also Figure 2 and Figure 3 An embodiment of the present invention is a stamping die with a discharge structure, wherein an adaptive adjustment component is arranged inside the discharge plate 9, and the adaptive adjustment component is used to adjust the contact state between the discharge plate 9 and the stamping part according to different shapes and sizes of the stamping part.

[0026] The adaptive adjustment component includes a movable groove 10 evenly arranged inside the discharge plate 9, a buffer spring 11 is embedded in the side wall of the movable groove 10, the other end of the buffer spring 11 is connected to a movable block 12, and one end of the movable block 12 is connected to an adjustment block 13.

[0027] The surface of the adjusting block 13 is covered with a flexible rubber 14 , the hardness of the flexible rubber 14 is 30-40 degrees Shore A, and the flexible rubber 14 is used to further protect the surface of the stamping die from being scratched during the discharge process.

[0028] Furthermore, the self - adaptive adjustment components arranged inside the discharge plate 9 and the first movable grooves 10 evenly distributed inside the discharge plate 9 provide a spatial basis for subsequent self - adaptive adjustment actions. A buffer spring 11 is embedded in the side wall of the first movable groove 10. The buffer spring 11 has good elastic deformation ability. When facing stamping parts with various shapes, the movable block 12 connected to the other end of the buffer spring 11 will compress or stretch the buffer spring 11 under the action of the stamping part and generate displacement in the first movable groove 10.

[0029] The adjustment block 13 connected to one end of the movable block 12 will move accordingly, so that the adjustment block 13 can fit the contour of the stamping part. The Shore A 30 - 40 degree flexible rubber 14 covering the surface of the adjustment block 13 is soft in texture and has a certain toughness. During the discharging process, the flexible rubber 14 contacts the surface of the stamping die, avoiding scratches that may be caused by rigid contact, greatly protecting the surface quality of the stamping die and extending the service life of the die.

[0030] For example, when the stamping part is a part with a complex curved surface, the adjustment block 13 can fit the curved surface in all directions through self - adaptive adjustment to ensure a smooth discharging process and prevent damage to the surface of the part.

[0031] Please refer to Figure 4 , an embodiment provided by the present invention: a stamping die with a discharging structure. A die ejecting component is arranged inside the lower die base 2. The die ejecting component is used to preliminarily lift the stamping die out of the female die 6 before discharging, and cooperate with the die pushing component to complete the discharging. The die ejecting component includes a second movable groove 15 opened inside the lower die base 2. The bottom wall of the second movable groove 15 is connected with a first hydraulic rod 16. The top of the first hydraulic rod 16 is connected with a blank holding plate 17, and the blank holding plate 17 is located inside the female die 6.

[0032] Furthermore, before discharging, the die ejecting component works first to prepare for the subsequent discharging process. The second movable groove 15 opened inside the lower die base 2 provides space for the installation and movement of the first hydraulic rod 16. The bottom of the first hydraulic rod 16 is fixed on the bottom wall of the second movable groove 15, and the top is connected with the blank holding plate 17. The blank holding plate 17 is located inside the female die 6. When the first hydraulic rod 16 receives a start signal, it starts to extend upward, pushing the blank holding plate 17 to preliminarily lift the stamping die located inside the female die 6.

[0033] By preliminarily lifting the stamping die by a certain height, the resistance when the discharge plate 9 pushes out the stamping die is reduced, making the discharging process smoother and greatly improving the discharging efficiency.

[0034] For example, for some female dies 6 with a larger depth and more complex shapes, the stamping die is likely to closely adhere to the bottom of the female die 6 after stamping.

[0035] Please refer to Figure 2 and Figure 5 For an embodiment provided by the present invention: a stamping die with a discharging structure, an auxiliary discharging component is connected to the top of the lower die base 2, and the auxiliary discharging component is used to continue to convey the stamping die after the stamping die is ejected. The auxiliary discharging component includes connecting plates 18 symmetrically connected to the top of the lower die base 2. A servo motor 19 is connected to the back of the rear set of connecting plates 18. The output end of the servo motor 19 is connected to a rotating shaft 20, and a conveying roller 21 is sleeved on the outer surface of the rotating shaft 20.

[0036] The outer surface of the conveying roller 21 is provided with an anti-slip rubber layer, and a spiral diversion groove is arranged on the surface of the anti-slip rubber layer. The depth of the diversion groove is 3-5 mm, and the diversion groove is used to guide the stamping part to move on the conveying roller 21 and prevent it from deviating during the rolling process.

[0037] One side of the lower die base 2 is connected with a discharging chute 22; The inner side wall of the discharging chute 22 is provided with a wear-resistant coating, and the wear-resistant coating is a tungsten carbide coating with a thickness of 0.5-1 mm; The inclination angle of the discharging chute 22 is 30°-45°.

[0038] Further, after the stamping die is ejected from the female die 6, the auxiliary discharging component starts to play a role to ensure that the stamping die can be smoothly conveyed continuously. The connecting plates 18 symmetrically connected to the top of the lower die base 2 provide a support structure for the installation of the auxiliary discharging component. The servo motor 19 is connected to the back of the rear set of connecting plates 18. The servo motor 19 has high-precision speed control ability. The output end of the servo motor 19 is connected to the rotating shaft 20. When the servo motor 19 is started, it will drive the rotating shaft 20 to rotate. The conveying roller 21 is sleeved on the outer surface of the rotating shaft 20, and the rotational movement of the rotating shaft 20 is transmitted to the conveying roller 21 to make it start to rotate.

[0039] The outer surface of the conveying roller 21 is provided with an anti-slip rubber layer, which increases the friction with the stamping die and prevents the stamping die from slipping during the conveying process. At the same time, the spiral diversion groove with a depth of 3-5 mm arranged on the surface of the anti-slip rubber layer can guide the stamping die to move in a predetermined direction when the stamping die rolls on the conveying roller 21 and prevent it from deviating during the rolling process.

[0040] For example, during the continuous stamping production process, after the stamping die is ejected from the female die 6, it will quickly fall on the conveying roller 21. The diversion groove can ensure that each stamping die can be accurately conveyed along the same path, avoiding the difficulties in subsequent processing caused by deviation.

[0041] On one side of the lower die base 2, there is a discharge chute 22 connected. The inner side wall of the discharge chute 22 is provided with a tungsten carbide wear-resistant coating with a thickness of 0.5 - 1 mm. Tungsten carbide has extremely high hardness and wear resistance, which can effectively resist the friction generated when the stamping die slides in the discharge chute 22 and extend the service life of the discharge chute 22. The inclination angle of the discharge chute 22 is designed to be 30° - 45°. This angle is calculated to ensure that the stamping die can slide smoothly under the action of gravity and will not be damaged due to too large an angle resulting in too fast a sliding speed of the stamping die.

[0042] Please refer to Figure 1 、 Figure 2 and Figure 5 As shown in, an embodiment provided by the present invention: A stamping die with a discharge structure. On the top of the lower die base 2, there is a guide post 23 connected. The outer surface of the guide post 23 is sleeved with a guide sleeve 24, and the guide sleeve 24 is embedded inside the upper die base 1; The other end of the guide post 23 is connected to the top wall of the stamping die protection body 7.

[0043] Inside the top of the stamping die protection body 7, there is a hydraulic rod three 25 embedded, and the output end of the hydraulic rod three 25 is connected to the top of the upper die base 1.

[0044] The stamping die protection body 7 is integrally formed with steel. Inside the stamping die protection body 7, there are reinforcing ribs, and the reinforcing ribs are used to enhance the structural strength of the stamping die protection body 7; On the front of the stamping die protection body 7, there is an openable maintenance door, and on the front of the maintenance door, there is an observation window.

[0045] Furthermore, the guide post 23 connected to the top of the lower die base 2, in cooperation with the guide sleeve 24, provides precise guiding for the movement of the upper die base 1. The outer surface of the guide post 23 is sleeved with the guide sleeve 24, and the guide sleeve 24 is embedded inside the upper die base 1, so that during the up and down movement of the upper die base 1, it can only move along the direction of the guide post 23, ensuring the centering accuracy of the punch 4 and the die 6 during stamping and avoiding quality problems of the stamped parts caused by misalignment.

[0046] The other end of the guide post 23 is connected to the top wall of the stamping die protection body 7, further enhancing the stability of the entire die structure. Inside the top of the stamping die protection body 7, there is a hydraulic rod three 25 embedded, and the output end of the hydraulic rod three 25 is connected to the top of the upper die base 1. The hydraulic rod three 25 can, according to the actual stamping requirements, assist in controlling the movement of the upper die base 1. For example, in the case of stamping some special materials or when precise pressure control is required, by adjusting the telescopic amount of the hydraulic rod three 25, the movement speed and pressure of the upper die base 1 can be adjusted.

[0047] The stamping die protection main body 7 is integrally formed of steel. This manufacturing method ensures the structural integrity and strength of the protection main body. Reinforcing ribs are provided inside it, which further enhance the structural strength of the stamping die protection main body 7, enabling it to better withstand the impact force and pressure during the stamping process.

[0048] An openable and closable maintenance door is provided on the front of the stamping die protection main body 7, which facilitates maintenance personnel to quickly enter the interior for inspection and repair when the die fails. An observation window is provided on the front of the maintenance door. During the operation of the die, the operator can observe the working conditions inside the die in real time through the observation window and promptly discover abnormal problems.

[0049] Working principle: A guide post 23 is connected to the top of the lower die base 2. A guide sleeve 24 is sleeved on the outer surface of the guide post 23. The guide sleeve 24 is embedded inside the upper die base 1. During the stamping process, when the upper die base 1 drives the punch 4 to move downward, the guide sleeve 24 slides along the guide post 23, ensuring that the upper die base 1 can only move along the direction of the guide post 23, ensuring the centering accuracy of the punch 4 and the die cavity 6 during stamping, and avoiding quality problems of the stamped parts caused by misalignment. The other end of the guide post 23 is connected to the top wall of the stamping die protection main body 7, enhancing the stability of the entire die structure.

[0050] A third hydraulic rod 25 is embedded in the top of the stamping die protection main body 7. The output end of the third hydraulic rod 25 is connected to the top of the upper die base 1. During the stamping process, according to the actual stamping requirements, such as stamping special materials or requiring precise pressure control, the third hydraulic rod 25 can assist in controlling the movement speed and pressure of the upper die base 1 by adjusting its own telescopic amount.

[0051] After stamping is completed, the die ejection assembly starts to work. A second movable groove 15 is opened inside the lower die base 2, and a first hydraulic rod 16 is connected to the bottom wall of the second movable groove 15.

[0052] When the first hydraulic rod 16 receives the start signal, the first hydraulic rod 16 extends. The top of the first hydraulic rod 16 is connected to a knockout plate 17. The knockout plate 17 is located inside the die cavity 6. As the first hydraulic rod 16 extends, it pushes the knockout plate 17 upward, initially ejecting the stamping die located in the die cavity 6, reducing the resistance for the discharge plate 9 in the subsequent die ejection assembly to eject the stamping die and making the discharging process smoother.

[0053] The second hydraulic rod 8 is started. The second hydraulic rod 8 is connected to a side wall of the stamping die protection main body 7. After starting, the second hydraulic rod 8 extends, driving the connected discharge plate 9 to move towards the die cavity 6.

[0054] An adaptive adjustment component is provided inside the discharge plate 9. When the discharge plate 9 approaches the stamping part, due to the different shapes and sizes of the stamping parts, the adjustment block 13 first contacts the stamping part. The adjustment block 13 is connected to one end of the movable block 12. The movable block 12 is located in the first movable groove 10. The first movable grooves 10 are evenly arranged inside the discharge plate 9, and buffer springs 11 are embedded in the side walls of the first movable grooves 10.

[0055] Under the action of the stamping part, the adjustment block 13 pushes the movable block 12 to move in the first movable groove 10, thereby compressing or stretching the buffer spring 11, enabling the adjustment block 13 to adapt to the contour of the stamping part and fit the surface of the stamping part. The surface of the adjustment block 13 is covered with flexible rubber 14 with a Shore A hardness of 30 - 40 degrees. During the discharging process, the flexible rubber 14 contacts the surface of the stamping die, preventing the discharge plate 9 from rigidly contacting the stamping die, thus protecting the surface of the stamping die from being scratched.

[0056] Subsequently, the auxiliary discharging component starts to work. Connecting plates 18 are symmetrically connected to the top of the lower die base 2, and a servo motor 19 is connected to the back of the rear set of connecting plates 18.

[0057] The servo motor 19 is started, and its output end is connected to the rotating shaft 20. The servo motor 19 drives the rotating shaft 20 to rotate. A conveying roller 21 is sleeved on the outer surface of the rotating shaft 20, and the rotational movement of the rotating shaft 20 is transmitted to the conveying roller 21, causing the conveying roller 21 to start rotating.

[0058] The outer surface of the conveying roller 21 is provided with an anti-slip rubber layer to increase the friction with the stamping die and prevent the stamping die from slipping during transportation. The surface of the anti-slip rubber layer is provided with spiral guide grooves with a depth of 3 - 5 mm. When the stamping die rolls on the conveying roller 21, the guide grooves guide the stamping die to move in a predetermined direction, preventing it from shifting during the rolling process.

[0059] One side of the lower die base 2 is connected with a discharge chute 22. The stamping die is finally fed into the discharge chute 22 under the conveyance of the conveying roller 21. The inner side wall of the discharge chute 22 is provided with a tungsten carbide wear-resistant coating with a thickness of 0.5 - 1 mm, which can resist the friction generated when the stamping die slides in the discharge chute 22. The inclination angle of the discharge chute 22 is 30° - 45°. Under the action of gravity, the stamping die slides smoothly along the discharge chute 22.

[0060] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed to multiple network units. Some or all of the modules can be selected according to actual needs to achieve the purpose of the solution of this embodiment. A person of ordinary skill in the art can understand and implement it without creative work.
