Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a mold for producing stamped hardware parts. Background Technology
[0002] As is well known, stamping dies for hardware production are specialized process equipment used in stamping processes to apply external force through a press, causing metal sheets and other blanks to separate or plastically deform, thereby mass-producing hardware products of specific shapes and sizes.
[0003] However, in traditional stamping hardware production dies, the plastic deformation of metal materials usually needs to be completed instantly during the stamping process. The upper die moves rapidly downward under the action of driving force (such as the punch press slide). When it comes into contact with the lower die, the reaction force of the material resisting deformation is released in a concentrated manner, resulting in the direct transmission of impact force. This can easily cause the die cutting edge, template and other parts to wear and crack due to long-term impact, shortening the service life of the die. Therefore, technical improvements are urgently needed. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a die for producing stamped hardware parts. When in use, the die slides along the guide rod with the guide sleeve and squeezes the pad and buffer spring. First, the elastic deformation of the spring absorbs part of the impact force. At the same time, the upper die base pushes the hinge rod, causing the sliding sleeve to slide along the fixed rod and compress the return spring. The spring reaction force further buffers the impact, forming a composite buffering effect. In addition, the damping rod on the lower die base works in conjunction with the shock-absorbing spring to attenuate the vibration energy through damping and reduce the impact on the forming plate.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A die for producing stamped hardware parts includes an upper die base, a lower die base at the lower end of the upper die base, guide rods fixedly connected to the four corners of the upper surface of the lower die base, buffer springs sleeved on the lower ends of the outer walls of the guide rods, and washers fixedly connected to the upper ends of the buffer springs. Multiple damping rods are fixedly connected to the edges of the upper surface of the lower die base, and shock-absorbing springs sleeved on the outer walls of the damping rods. Storage slots are formed on both sides of the upper surface of the lower die base, and fixing rods are fixedly connected to both ends of the inner walls of the storage slots. Return springs are sleeved on both ends of the outer walls of the fixing rods, and sliding sleeves are fixedly connected to the outer walls of adjacent ends of the return springs. Hinge rods are hinged to the upper ends of the sliding sleeves.
[0007] Compared with existing stamping hardware production dies, this stamping hardware production die, through the above technical solution, uses a guide sleeve that slides along the guide rod and squeezes the pad and buffer spring. First, the elastic deformation of the spring absorbs part of the impact force. At the same time, the upper die base pushes the hinge rod, causing the sliding sleeve to slide along the fixed rod and compress the return spring. The spring reaction force further buffers the impact, forming a composite buffering effect. In addition, the damping rod on the lower die base works with the shock-absorbing spring to attenuate the vibration energy through damping, reducing the impact on the forming plate.
[0008] Furthermore, guide sleeves are connected through to the four corners of the lower surface of the upper mold base. Each guide sleeve is slidably connected to the outer wall of the guide rod and its lower end is tightly fitted to the upper end of the gasket.
[0009] The above technical solution, through the cooperation of guide sleeve and guide rod, can accurately guide the movement of the upper die holder relative to the lower die holder, ensuring that the upper die is accurately positioned during the stamping process and avoiding deviation.
[0010] Furthermore, each of the gaskets is slidably connected to the outer wall of the guide rod;
[0011] With the above technical solution, the gaskets are slidably connected to the outer wall of the guide rod, and can move with the upper mold base.
[0012] Furthermore, a pressure plate is fixedly connected to the lower end of the lower mold base;
[0013] The above technical solution facilitates the shaping of raw materials through the pressure plate.
[0014] Furthermore, a molded plate is fixedly connected to the upper end of the damping rod;
[0015] The above technical solution effectively absorbs the vibration and impact force generated during the stamping process through the damping rod.
[0016] Furthermore, the sliding sleeves are slidably connected to the outer walls of the two fixed rods respectively, and the outer walls of the opposite ends of the reset springs are fixedly connected to the two ends of the inner wall of the storage groove respectively.
[0017] The above technical solution allows the sliding sleeve to easily compress the return spring.
[0018] Furthermore, the upper ends of the hinge rods are all hinged to both sides of the lower surface of the upper mold base;
[0019] With the above technical solution, the upper ends of the hinge rods are all hinged to both sides of the lower surface of the upper mold base, which facilitates pushing the lower hinge rods to drive the sliding sleeve to slide.
[0020] This utility model has the following beneficial effects:
[0021] 1. The present invention proposes a die for producing stamped hardware parts. Compared with existing dies for producing stamped hardware parts, when this die is used, the guide sleeve slides along the guide rod and squeezes the pad and buffer spring. First, the elastic deformation of the spring absorbs part of the impact force. At the same time, the upper die base pushes the hinge rod, so that the sliding sleeve slides along the fixed rod and compresses the reset spring. The spring reaction force is used to further buffer the impact, forming a composite buffering effect. In addition, the damping rod on the lower die base cooperates with the shock-absorbing spring to attenuate the vibration energy through damping and reduce the impact on the forming plate.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Reference Figure 1-5This utility model provides an embodiment of a mold for producing stamped hardware parts, including an upper mold base 1, a lower mold base 13 at the lower end of the upper mold base 1, guide rods 14 fixedly connected to the four corners of the upper surface of the lower mold base 13, buffer springs 15 sleeved on the lower end of the outer wall of the guide rods 14, and shims 16 fixedly connected to the upper end of the buffer springs 15. Multiple damping rods 17 are fixedly connected to the edge of the upper surface of the lower mold base 13, and shock-absorbing springs 18 are sleeved on the outer wall of the damping rods 17. Storage slots 2 are opened on both sides of the upper surface of the lower mold base 13, and fixing rods 21 are fixedly connected to both ends of the inner wall of the storage slots 2. Reset springs 22 are sleeved on both ends of the outer wall of the fixing rods 21, and sliding sleeves 23 are fixedly connected to the outer wall of the adjacent end of the reset springs 22. Hinged rods 24 are hingedly connected to the upper end of the sliding sleeves 23.
[0031] Compared with existing stamping hardware production dies, when this stamping hardware production die is used, the guide sleeve 11 slides along the guide rod 14 and squeezes the pad 16 and the buffer spring 15. First, the elastic deformation of the spring absorbs part of the impact force. At the same time, the upper die base 1 pushes the hinge rod 24, so that the sliding sleeve 23 slides along the fixed rod 21 and compresses the return spring 22. The spring reaction force is used to further buffer the impact, forming a composite buffering effect. In addition, the damping rod 17 on the lower die base 13 cooperates with the shock-absorbing spring 18 to attenuate the vibration energy through the damping effect and reduce the impact on the forming plate 19.
[0032] Guide sleeves 11 are connected through to the four corners of the lower surface of the upper mold base 1. The guide sleeves 11 are slidably connected to the outer wall of the guide rod 14 and their lower ends are tightly fitted to the upper end of the gasket 16.
[0033] By cooperating with the guide sleeve 11 and the guide rod 14, the movement of the upper die holder 1 relative to the lower die holder 13 can be precisely guided, ensuring that the upper die is accurately positioned during the stamping process and avoiding deviation.
[0034] The gaskets 16 are all slidably connected to the outer wall of the guide rod 14;
[0035] Each of the gaskets 16 is slidably connected to the outer wall of the guide rod 14, and can move with the upper mold base 1.
[0036] A pressure plate 12 is fixedly connected to the lower end of the lower mold base 13;
[0037] The pressure plate 12 facilitates the shaping of the raw materials.
[0038] A molding plate 19 is fixedly connected to the upper end of the damping rod 17;
[0039] The damping rod 17 can effectively absorb the vibration and impact force generated during the stamping process.
[0040] The sliding sleeves 23 are slidably connected to the outer walls of the two fixed rods 21 respectively, and the outer walls of the opposite ends of the return springs 22 are fixedly connected to the two ends of the inner wall of the storage groove 2 respectively.
[0041] The sliding sleeve 23 facilitates the compression of the return spring 22.
[0042] The upper ends of the hinge rods 24 are all hinged to both sides of the lower surface of the upper mold base 1;
[0043] The upper ends of the hinge rods 24 are hinged to both sides of the lower surface of the upper mold base 1, which facilitates pushing the lower hinge rods 24 to drive the sliding sleeve 23 to slide.
[0044] Working principle: During use, the upper die holder 1 moves downward, and the guide sleeve 11 on its lower surface slides precisely along the guide rod 14 on the lower die holder 13 to ensure accurate stamping alignment. As the upper die holder 1 descends, the lower end of the guide sleeve 11 presses against the pad 16. The pad 16 slides along the guide rod 14 and compresses the buffer spring 15, initially absorbing impact energy through spring deformation. At the same time, the upper die holder 1 pushes the hinge rods 24 on both sides, causing the hinge rods 24 to drive the sliding sleeve 23 to slide along the fixed rod 21 in the storage slot 2. The sliding sleeve 23 compresses the return spring 22, forming a secondary buffer using the spring reaction force. During the stamping process, the upper die holder 1 acts on the forming plate 19. The damping rod 17 below the forming plate 19 cooperates with the shock-absorbing spring 18 to further attenuate vibration energy through damping and spring deformation, reducing the impact on the die.
