Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a stamping mold that facilitates material discharge. Background Technology
[0002] Hardware components have a wide range of applications in modern industrial production, covering many fields such as electronic equipment, automobile manufacturing, machinery equipment, and home appliances. The shapes and structures of hardware components are becoming increasingly complex, leading to higher requirements for processing precision and production efficiency. Stamping, as one of the main methods of hardware component manufacturing, has advantages such as high production efficiency, low cost, and stable product quality.
[0003] Currently, in traditional small stamping dies, the waste generated from punching is generally discharged to the bottom of the die through the waste discharge hole. Small stamping dies are usually placed directly on the workbench for use, and do not have a dedicated waste discharge system like large stamping equipment. Therefore, the discharged waste will temporarily accumulate at the bottom of the die, and then the accumulated waste needs to be cleaned manually periodically to push out the waste accumulated at the bottom. This requires workers to frequently stop the machine to clean the waste, resulting in poor production continuity and seriously affecting production efficiency.
[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content
[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for easy material discharge, comprising an upper die base, wherein an upper die plate, a lower die plate, a fixed base and a lower die base are sequentially arranged at the lower end of the upper die base, and guide posts are provided at the four corners between the upper die base and the lower die plate, and the four corners of the upper die plate are guided and connected to the guide posts, a hydraulic cylinder acting on the upper die plate is installed on the upper die base, and a punch is provided at the lower end of the upper die plate, wherein the upper die plate and the lower die plate are closed by the hydraulic cylinder so that the punch performs a punching operation on the workpiece;
[0007] The lower template is provided with a waste discharge hole, and the lower end of the fixed base has a waste channel that penetrates the fixed base. The waste discharge hole is connected to the waste channel.
[0008] A movable seat is slidably disposed inside the waste channel. One end of the movable seat protrudes from the waste channel, and a push plate is disposed at the other end. The push plate is close to the lower end of the waste discharge hole.
[0009] A lower pressure seat is provided on one side of the upper mold plate. The lower end of the lower pressure seat extends downward and cooperates with the moving seat protruding from the waste channel, so that when the upper mold plate and the lower mold plate are closed, the lower pressure seat drives the moving seat to move into the waste channel.
[0010] An elastic reset mechanism is provided between the lower end of the movable seat and the lower mold base, which is used to reset the movable seat when the upper mold plate and the lower mold plate are opened.
[0011] As a further embodiment of this utility model: the elastic reset mechanism includes a movable groove opened on the upper end face of the lower mold base, and a sliding block movably connected to the inside of the movable groove is provided at the lower end of the movable base. A first elastic element is provided between the side of the sliding block facing the waste discharge hole and the movable groove.
[0012] In this process, the first elastic element pushes the sliding block against the side of the inner wall of the movable groove away from the waste discharge hole.
[0013] As a further embodiment of this utility model: a pressure plate is provided on one side of the waste channel, the pressure plate is located at the lower end of the waste discharge hole away from the moving seat, and a number of second elastic elements are provided between the upper end of the pressure plate and the top wall of the waste channel;
[0014] The pressure plate is configured with an upwardly curved shape at the end near the waste discharge hole.
[0015] As a further embodiment of this utility model: a guide cover is provided on one side of the lower template, the guide cover is fixedly connected to the lower template and the fixed seat, and the lower pressing seat is connected to the guide cover for internal guiding cooperation.
[0016] As a further embodiment of this utility model: a baffle is provided at the top of the waste channel, and the baffle is located above the push plate and close to the edge of the waste discharge hole.
[0017] Compared with the existing technology, the beneficial effects of this technical solution are as follows: When the upper and lower mold plates close, the lower pressure seat and the moving seat cooperate to drive the moving seat to move into the waste channel. The moving seat drives the push plate to push the waste material that fell during the previous punching at the lower end of the waste discharge hole out of the lower end of the waste discharge hole. Then, when the upper mold plate opens after punching, the upper mold plate drives the lower pressure seat to disengage from the moving seat. At the same time, the elastic reset mechanism pushes the moving seat to reset, so as to drive the push plate away from the lower end of the waste discharge hole, so that the waste material generated by the punching will fall back into the waste channel. This process is repeated. When punching again, the push plate will push the waste material in the waste channel outward again. Through the mutual pushing between the waste materials, the waste material is finally pushed out of the waste channel. The automatic discharge of waste material is achieved by cleverly utilizing the sliding mechanism structure, which facilitates the discharge of waste material from small stamping dies. There is no need for manual shutdown for cleaning, which improves production continuity and thus improves production efficiency.

[0025] 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.
[0026] Please see Figure 1-3 A stamping die for easy material discharge includes an upper die base 1. An upper template 2, a lower template 3, a fixed base 4, and a lower die base 5 are arranged sequentially at the lower end of the upper die base 1. Guide posts 6 are provided at the four corners between the upper die base 1 and the lower template 3. The four corners of the upper template 2 are guided and connected to the guide posts 6. A hydraulic cylinder 7 that acts on the upper template 2 is installed on the upper die base 1. A punch 8 is provided at the lower end of the upper template 2. The hydraulic cylinder 7 drives the upper template 2 and the lower template 3 to close the die, so that the punch 8 can perform a punching operation on the workpiece.
[0027] Specifically, during the punching process, the workpiece is placed on the lower template 3, wherein, reference Figure 1 and Figure 2A workpiece placement base plate is also installed on the lower template 3. The placement base plate has a workpiece positioning groove. The workpiece can be positioned and placed using the workpiece positioning groove to ensure that the punching position of the workpiece is accurate each time. After the workpiece is placed, the upper template 2 and the lower template 3 are closed by the hydraulic cylinder 7, so that the punch 8 at the lower end of the upper template 2 punches the workpiece when the mold is closed. The four corners of the upper template 2 are connected to the guide post 6 to ensure that the movement trajectory of the upper template 2 remains vertical, so as to ensure the punching accuracy and avoid the deviation of the punching position.
[0028] The lower template 3 is provided with a waste discharge hole 9, and the lower end of the fixed seat 4 has a waste channel 10 that penetrates the fixed seat 4. The waste discharge hole 9 is connected to the waste channel 10.
[0029] Furthermore, after the punch 8 completes the punching process on the workpiece, the waste material cut off by the punch 8 will fall into the waste channel 10 through the waste discharge hole 9.
[0030] A movable seat 11 is slidably disposed inside the waste channel 10. One end of the movable seat 11 protrudes out of the waste channel 10, and a push plate 12 is disposed at the other end. The push plate 12 is close to the lower end of the waste discharge hole 9.
[0031] A lower pressure seat 13 is provided on one side of the upper mold plate 2. The lower end of the lower pressure seat 13 extends downward and cooperates with the moving seat 11 that protrudes from the waste channel 10, so that when the upper mold plate 2 and the lower mold plate 3 are closed, the lower pressure seat 13 drives the moving seat 11 to move into the waste channel 10.
[0032] An elastic reset mechanism 14 is provided between the lower end of the movable seat 11 and the lower mold seat 5, which is used to reset the movable seat 11 when the upper mold plate 2 and the lower mold plate 3 are opened.
[0033] Specifically, in the technical solution of this utility model, the hydraulic cylinder 7 drives the upper template 2 to close the mold, so that while the punch 8 punches the workpiece, the upper template 2 drives the lower pressure seat 13. The lower pressure seat 13 cooperates with the moving seat 11, so that the lower pressure seat 13 drives the moving seat 11 to move into the waste channel 10. The moving seat 11 drives the push plate 12, so that the push plate 12 pushes the waste material that fell during the previous punching at the lower end of the waste discharge hole 9 out of the range of the lower end of the waste discharge hole 9. Then, when the punching is completed and the hydraulic cylinder 7 drives the upper template 2 to open the mold, the upper template 2 drives the lower pressure seat 13 to disengage from the moving seat 10. The seat 11 is simultaneously pushed to reset by the elastic reset mechanism 14, so as to drive the push plate 12 away from the lower end of the waste discharge hole 9, so that the waste generated by the punching will fall back into the waste channel 10. This process is repeated. When punching is performed again, the push plate 12 will push the waste in the waste channel 10 outward again. Through the mutual pushing between the wastes, the waste is finally pushed out of the waste channel 10. The automatic discharge of waste is achieved by cleverly using the sliding machine structure, which facilitates the waste discharge of small stamping dies. There is no need for manual shutdown for cleaning, which improves production continuity and thus improves production efficiency.
[0034] Among them, such as Figure 2 As shown, the upper end face of the portion of the movable seat 11 that protrudes from the waste channel 10 has an upward inclined surface, while the bottom end of the lower pressure seat 13 has a downward inclined surface with the same inclination angle as the upward inclined surface of the movable seat 11. As the lower pressure seat 13 moves downward with the upper template 2, the downward inclined surface gradually contacts and interacts with the upward inclined surface of the movable seat 11. Since the downward and upward inclined surfaces have the same inclination angle, according to the mechanical principle of the inclined surface, when the lower pressure seat 13 moves vertically downward, it will generate a horizontal component force on the movable seat 11, thereby converting the vertical pressure into the power to drive the movable seat 11 to move into the waste channel 10. Furthermore, the length, width, and height of the waste channel 10 are consistent with those of the movable seat 11, which has the function of guiding the movement trajectory of the movable seat 11, thereby improving the effectiveness of force conversion and making the movement of the movable seat 11 smoother.
[0035] In this embodiment, please refer to Figures 2-3 Furthermore, the elastic reset mechanism 14 includes an active groove 15 opened on the upper end face of the lower mold base 5, and a sliding block 16 movably connected to the inside of the active groove 15 at the lower end of the movable base 11. A first elastic element 17 is provided between the side of the sliding block 16 facing the waste discharge hole 9 and the active groove 15.
[0036] Among them, the first elastic element 17 pushes the sliding block 16 to press against the inner wall of the movable groove 15 away from the waste discharge hole 9;
[0037] During the process of the moving seat 11 being pushed by the lower pressure seat 13 and driving the push plate 12 to complete the material pushing operation, the sliding block 16 at the lower end of the moving seat 11 will squeeze the first elastic element 17 (which can be a spring, nitrogen spring, etc.) between it and the movable groove 15, so that when the lower pressure seat 13 moves up with the upper template 2, the lower pressure seat 13 separates from the moving seat 11. The first elastic element 17 uses the elastic potential energy stored when it is squeezed to push the sliding block 16, thereby moving the moving seat 11 to its original position so that the lower pressure seat 13 can press down on the moving seat 11 during the next punching.
[0038] When the movable seat 11 is reset, the sliding block 16 just abuts against the inner wall of the movable groove 15. The position of the sliding block 16 is limited by the movable groove 15, thereby controlling the maximum range of movement of the movable seat 11 and preventing the movable seat 11 from moving outward too much, which would cause a positional shift between it and the lower pressure seat 13.
[0039] In this embodiment, it is further proposed that a pressure plate 18 is provided on one side of the waste channel 10. The pressure plate 18 is located on the side away from the moving seat 11 at the lower end of the waste discharge hole 9. A number of second elastic elements 19 are provided between the upper end of the pressure plate 18 and the top wall of the waste channel 10.
[0040] Among them, the pressure plate 18 is arranged in an upward curved shape at the end near the waste discharge hole 9;
[0041] Furthermore, as the pusher plate 12 continuously pushes the waste material falling from the waste discharge hole 9 toward the outlet of the waste channel 10, the pressure plate 18 can restrict the up and down movement of the waste material pushed by the pusher plate 12, thereby preventing the waste material from piling up and preventing the waste material from accumulating in the waste channel 10, which would cause the waste material to squeeze against each other when the pusher plate 12 pushes the material until it can no longer be pushed, thus causing damage to the parts.
[0042] Meanwhile, the scrap pieces generated during punching may deform and warp under the stamping process, preventing them from entering the bottom of the pressure plate 18. The pressure plate 18 is connected to the upper wall of the scrap channel 10 via the second elastic element 19, allowing the pressure plate 18 to move up and down. The end of the pressure plate 18 near the waste discharge hole 9 is set in an upward curved shape, so that when the warped scrap is pushed towards the pressure plate 18 by the push plate 12, the scrap comes into contact with the curved part, causing the pressure plate 18 to gradually move upward, allowing the scrap to enter the bottom of the pressure plate 18. The elastic potential energy of the second elastic element 19 allows the pressure plate 18 to always hold the scrap, and when new scrap is pushed in, the upward movement of the pressure plate 18 also provides conditions for the existing scrap to move forward.
[0043] In this embodiment, a guide cover 20 is further provided on one side of the lower template 3. The guide cover 20 is fixedly connected to the lower template 3 and the fixing seat 4, and the lower pressing seat 13 is connected to the guide cover 20 through a guide engagement.
[0044] Preferably, the space formed by the guide cover 20 and the lower template 3 and the fixed seat 4 is utilized, and the lower pressure seat 13 is guided and matched with the inside of the guide cover 20, thereby further limiting the movement trajectory of the lower pressure seat 13, improving the movement accuracy, and improving the power conversion between the lower pressure seat 13 and the moving seat 11.
[0045] In this embodiment, it is further proposed that a baffle plate 21 is provided at the top of the waste channel 10, and the baffle plate 21 is located above the push plate 12 and close to the edge of the waste discharge hole 9;
[0046] Preferably, by providing a baffle 21 at the top of the waste channel 10, located at the edge of the waste discharge hole 9, the waste from the push plate 12 can be prevented from falling onto it. When the push plate retracts, the baffle 21 can block the waste, causing the waste to fall back into the waste channel 10, so as to avoid affecting the discharge of the waste.
[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
