[0002] In the field of modern electronic equipment manufacturing, to achieve compact circuit connections, electrical equipment is often equipped with numerous miniature hardware components. These miniature hardware components are typically manufactured using stamping processes. However, stamping operations inevitably generate a large amount of fine metal waste.

[0003] The traditional method for handling metal scrap generated during stamping involves installing multiple vertical plates beneath the die. These plates are adjacent to each other, forming a grid structure with some space between them. During the stamping operation, small pieces of metal scrap naturally fall into these grids. However, this method has significant drawbacks. When the scrap accumulates to a certain amount in the grids, manual cleaning is required. Manual cleaning is not only labor-intensive but also extremely inefficient. The entire process is tedious and complex, severely impacting the continuity and efficiency of production. In today's manufacturing environment, which prioritizes efficient production and cost control, this traditional method of handling metal scrap urgently needs improvement. Utility Model Content

Detailed Implementation

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figure 1-5 In this embodiment of the present invention, a continuous stamping die for miniature hardware parts that facilitates waste discharge includes an upper die body 10 and a lower die body 20 that cooperate to stamp strips of material for making hardware parts. A base plate 21 and multiple upright plates 22 mounted on the base plate 21 are provided at the lower end of the lower die body 20. Multiple grids are formed at the lower end of the lower die body 20 through the base plate 21 and the upright plates 22. The lower die body 20 has waste through holes 23 penetrating the grids, and inclined guide plates 24 extending to one side of the lower die body 20 are installed in the grids. A waste conveying mechanism 30, which engages with the inclined guide plates 24, is installed on one side of the lower die body 20. Wherein:

[0027] The waste conveying mechanism 30 includes a conveyor belt 31 installed on one side of the lower mold body 20, a one-way bearing 32 connected to the conveyor belt 31, a transmission gear 33 connected to the one-way bearing 32, and a rack assembly 34 installed on one side of the upper mold body 10 and capable of meshing with the transmission gear 33. The one-way bearing 32 is configured to rotate freely in a first direction and lock in a second direction. The rack assembly 34 drives the transmission gear 33 to rotate in the first direction during the mold closing process and drives the transmission gear 33 to rotate in the second direction during the mold opening process.

[0028] By integrating a linked scrap conveying mechanism 30 into a traditional continuous stamping die, and using an inclined guide plate 24 to guide the scrap material out of the scrap conveying mechanism 30, at the start of the stamping operation, the upper die body 10 and the lower die body 20 cooperate to stamp the material strip. The resulting small pieces of scrap metal fall through the scrap through-hole 23 of the lower die body 20 into the grid formed by the base plate 21 and the vertical plate 22. The scrap slides down into the grid to the inclined guide plate 24, and is guided by the inclined surface of the inclined guide plate 24 to slide down smoothly. During the die closing stage, the upper die body 10 moves downward. The rack assembly 34 moves down and meshes with the transmission gear 33, driving it to rotate. Since the one-way bearing 32 rotates freely in the first direction, the transmission gear 33 idles at this time, and the conveyor belt 31 does not run. When the mold opens, the upper mold body 10 rises, and the rack assembly 34 drives the transmission gear 33 to rotate in the second direction. The one-way bearing 32 then locks, and the transmission gear 33 drives the one-way bearing 32, which in turn drives the conveyor belt 31 to run, conveying the waste material that slides from the inclined guide plate 24 onto the belt. This cycle continues, completing the continuous discharge of waste material.

[0029] This setup utilizes an automatic waste discharge mechanism and a waste conveying mechanism 30 that is linked to the mold opening and closing actions, eliminating the need for an additional power source. This mechanism greatly improves cleaning efficiency, changing the traditional situation where manual cleaning requires waiting for waste to accumulate. It enables stamping and waste cleaning to proceed simultaneously, resulting in a smoother and more efficient production process. Furthermore, labor costs are significantly reduced, as frequent manual waste cleaning is no longer necessary, and manpower can be allocated to other critical production stages. In addition, this automated operation reduces human error and improves production stability and product quality consistency.

[0030] Please see Figure 1-3 Based on the above technical solution, it is further proposed that the upper mold body 10 is provided with a top plate 11, the front end of the top plate 11 has a first extension section, the rack assembly 34 includes a first extension plate 341 installed at the lower end of the first extension section, a first fixing plate 342 installed on the first extension plate 341 and the side of the first extension section, and a rack body 343 fixedly connected to the first fixing plate 342. The lower section of the rack body 343 is provided with teeth 344, and the lower section of the rack body 343 meshes with the transmission gear 33 through the teeth 344; this makes the installation of the rack assembly 34 more stable and reasonable, ensuring that the rack body 343 can accurately mesh with the transmission gear 33 when it moves with the upper mold body 10, stably transmit power, and ensure the normal operation of the waste conveying mechanism 30. In addition, a guide rail assembly 40 is provided on one side of the lower die body 20. The rack body 343 is guided and engaged with the lower die body 20 through the guide rail assembly 40. The base plate 21 has a second extension section at its front end. The guide rail assembly 40 includes a second extended section 41 installed on the second extended section, a second fixed plate 42 installed on the side of the second extended section and the second extended section 41, and a vertical linear guide rail 43 fixedly connected to the second fixed plate 42. The lower section of the rack body 343 is slidably connected to the vertical linear guide rail 43. During the stamping process, the movement trajectory of the rack body 343 is effectively restricted, reducing shaking and deviation, making the waste discharge process smoother, reducing the probability of failure caused by structural instability, further improving production efficiency and product quality, and extending the service life of the equipment.

[0031] Please see Figure 3 Based on the above technical solution, a further proposed inclined guide plate 24 has an inclined portion 241 and fixing portions 242 located on both sides of the inclined portion 241. The inclined guide plate 24 is fixedly connected to the vertical plate 22 through the two fixing portions 242, so that the inclined guide plate 24 is fixed between two adjacent vertical plates 22 through the fixing portions 242. This allows it to be stably fixed between adjacent vertical plates 22, and its installation and disassembly are convenient, facilitating equipment maintenance and parts replacement, and improving the overall durability and maintainability of the equipment.

[0032] Please see Figure 1-5Based on the above technical solution, the conveyor belt 31 is further proposed to include a fixed frame 311 fixedly installed on one side of the base plate 21 and extending beyond the rear end of the base plate 21, a drive roller 312 with bearings connected to the front end of the fixed frame 311, a driven roller 313 with bearings connected to the rear end of the fixed frame 311, and a belt body 314 sleeved on the drive roller 312 and the driven roller 313. A one-way bearing 32 is axially connected to the drive roller 312. In terms of design, the cross-sections of the drive roller 312 and the driven roller 313 gradually increase from the middle to both ends, and the belt body 314 is adapted to the drive roller 312 and the driven roller 313. This significantly enhances the stability and friction of the belt body 314 during operation and helps to prevent waste from overflowing from both sides of the belt body 314, ensuring that waste can be conveyed stably and efficiently. A waste bin 50 is provided below the rear end of the conveyor belt 31 to receive waste, providing a convenient and efficient way to collect waste, and also facilitating centralized recycling and reuse.

[0033] Please see Figure 5 Based on the above technical solution, it is further proposed that a brush 60 is also provided at the lower end of the fixing frame 311. The brush 60 is connected and cooperates with the belt body 314, and the brush 60 is located directly above the waste bin 50. During the operation of the belt, the brush 60 scrapes the waste material down to the waste bin 50 directly below, avoiding the waste material from circulating with the belt, reducing the risk of secondary pollution from the waste material, ensuring the cleanliness of the belt, reducing belt wear caused by waste material residue, and extending the service life of the belt.

[0034] 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 exemplary 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.
