However, the waste material falling on the lower mold will affect the precision of product processing.

[0006] To address the aforementioned issues, this utility model provides a stamping die for 3C electronic products, comprising a base with a working platform, a support plate mounted on the top of the base, a hydraulic cylinder fixedly connected to the top of the base, and an upper die connected to the output end of the hydraulic cylinder via a connecting shaft, a lower die fixedly connected to the working platform directly below the support plate, a support shaft fixedly connected to the side of the lower die on the working platform, a rotating shaft rotatably connected to the middle of the support shaft extending into the base, a scraper detachably connected to the rotating shaft, the scraper contacting the top of the lower die, a through hole on the side wall of the rotating shaft, a threaded shaft fixedly connected to one end of the scraper near the rotating shaft, the threaded shaft passing through the through hole and secured by a nut thread, a servo motor fixedly connected inside the base, the output end of the servo motor connected to the rotating shaft, a protective cover fitted around the outer ring of the base, and a material discharge port at the bottom of the protective cover.

[0007] In the above-mentioned stamping die, by setting up a scraper that is easy to disassemble and replace, it is convenient to clean the waste left on the lower die after each stamping, so as to avoid the waste residue affecting the stamping accuracy of the product. In addition, a protective cover is set up to collect the waste and screen it through a filter screen for secondary use later.

[0008] As a further improvement of this application, protective pads are fixedly installed at the four corners of the outer ring of the base, and electric actuators are embedded in the top of the protective pads, with the movable end of the electric actuators connected to the bottom of the protective cover.

[0009] As a further improvement of this application, a support plate is fixedly connected to the protective cover wall, and a filter screen is placed on the support plate, and the filter screen is engaged with the inner wall of the protective cover.

[0010] As a further improvement of this application, an air outlet is embedded in the inner wall of the protective cover above the filter screen, and the bottom of the air outlet is flush with the top of the filter screen.

[0011] As another improvement of this application, the air outlet is provided with a connection port, and an air inlet pipe is connected to the connection port by internal thread, and the air inlet pipe is fixed to the side wall of the protective cover by a clamp.

[0012] As a further improvement to this application, a blower is connected to the end of the two adjacent air inlet pipes away from the connection port, and an electric air valve is fixedly connected to the connection point between the two air inlet pipes and the output end of the blower.

The controller starts the hydraulic cylinder to drive the upper mold to stamp the product. After stamping, when the upper mold resets, the controller automatically starts the servo motor to drive the rotating shaft to rotate the scraper located on the side of the lower mold. The rotating scraper cleans the waste generated by stamping on the surface of the lower mold and it falls onto the working platform. After processing is completed, a recycling bin is placed at the bottom of the protective cover. The waste on the working platform can be swept into the protective cover and fall onto the filter screen for filtration. Powder and dust are filtered to the bottom of the protective cover, large particles of waste are filtered onto the filter screen, and powder falls from the discharge port into the recycling bin for collection. The waste on the filter screen is then collected separately for recycling. Attached Figure Description

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-7 A stamping die for 3C electronic products is shown, including a base 1 with a working platform. A support plate 17 is installed on the top of the base 1 above the working platform. A hydraulic cylinder 19 is fixedly connected to the top of the base 1, and the output end of the hydraulic cylinder 19 is connected to an upper die through a connecting shaft. A lower die 6 is fixedly connected to the working platform directly below the support plate 17. A support shaft 7 is fixedly connected to the side of the lower die 6 on the working platform. A rotating shaft 10 extending into the base 1 is rotatably connected to the middle of the support shaft 7. A scraper 8 is detachably connected to the rotating shaft 10 and contacts the top of the lower die 6. A through hole is opened on the side wall of the rotating shaft 10. A threaded shaft 12 is fixedly connected to one end of the scraper 8 near the rotating shaft 10, and the threaded shaft 12 passes through the through hole and is fixed by a nut 13. A servo motor 11 is fixedly connected inside the base 1, and the output end of the servo motor 11 is connected to the rotating shaft 10. A protective cover 2 is fitted around the outer ring of the base 1, and a material discharge port 16 is opened at the bottom of the protective cover 2.

[0027] A support plate 15 is fixedly connected to the wall of the protective cover 2. A filter screen 14 is placed on the support plate 15 and the filter screen 14 is engaged with the inner wall of the protective cover 2. A controller for controlling the electric air valve, blower, electric push rod 5, air outlet 3 and servo motor 11 is fixedly connected to the base 1.

[0028] The servo motor uses existing technology, and those skilled in the art can select a suitable servo motor from the existing technology for installation, such as MINAS-A5.

[0029] Working principle: The scraper 8 is inserted into the through hole through the threaded shaft 12 and fixed by the nut 13. Then, the product raw material is placed in the lower mold 6. The controller opens the oil cylinder 19 to drive the upper mold to stamp the product. After stamping, when the upper mold is reset, the controller automatically opens the servo motor 11 to drive the rotating shaft 10 to rotate the scraper 8 located on the side of the lower mold 6. The scraper 8 rotates to clean the waste generated by the stamping on the surface of the lower mold 6 and it falls onto the working platform. After processing is completed, a recycling bin is placed at the bottom of the protective cover 2 at the discharge port 16. The waste on the working platform can be swept into the protective cover 2 and fall onto the filter screen 14 for filtration. The powder and dust are filtered to the bottom of the protective cover 2, and large particles of waste are filtered onto the filter screen 14. The powder falls from the discharge port 16 into the recycling bin for collection. The waste on the filter screen 14 is then collected separately for recycling.

[0030] The scraper 8 is designed for easy disassembly and replacement, which facilitates the cleaning of waste material left on the lower die 6 after each stamping, thus preventing waste residue from affecting the stamping accuracy of the product. The protective cover 2 is also designed to collect the waste material and sieve it through the filter screen 14. Through the graded filtration design, the problem of waste residue affecting processing accuracy is solved, and the material recycling rate is also improved.

[0031] Second implementation method:

[0032] Figure 2 and Figures 6-7 The base 1 has protective pads 20 fixedly installed at the four corners of its outer ring. The top of the protective pads 20 is embedded with electric push rods 5, and the movable end of the electric push rods 5 is connected to the bottom of the protective cover 2. The inner wall of the protective cover 2 is embedded with an air outlet 3 above the filter screen 14, and the bottom of the air outlet 3 is flush with the top of the filter screen 14. The air outlet 3 is provided with a connection port 4, and the connection port 4 is internally threaded with an air inlet pipe 9. The air inlet pipe 9 is fixed to the side wall of the protective cover 2 by a clamp 18. The ends of two adjacent air inlet pipes 9 away from the connection port 4 are connected to a blower, and electric air valves are fixedly connected to the connection points of the two air inlet pipes 9 and the output ends of the blowers. The top area of ​​the protective cover 2 is the same as the cross-sectional area of ​​the support plate 17, and when the top of the protective cover 2 touches the bottom of the support plate 17, the air outlet 3 is flush with the working platform.

[0033] Working principle: First, the material outlet 16 is blocked with a sealing plug. After the stamping cycle is completed, the controller first starts the electric push rod 5 to lift the protective cover 2 so that it contacts the bottom of the support plate 17, forming a sealed space on the working platform. Then, the blower can be turned on, and the air outlets 3 around the perimeter can be opened in sequence by controlling the electric air valve to blow the waste material on the working platform into the protective cover 2 for screening.

[0034] By adjusting the height of the protective cover 2, the work platform can be made into a sealed space. The air blower 3 is used to clean up the waste falling on it, thus achieving automatic cleaning while preventing dust.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
