[0002] A powder forming machine is a specialized piece of equipment used for the pressing and forming process of powder materials. Its core function is to achieve the precision forming of powder materials through a mold frame structure and pressure system.

[0003] Currently, the feeding mechanism of powder molding machines generally uses a cylinder to drive the material box to move back and forth. When the material box passes the female mold, the powder material is filled into the female mold to achieve feeding. However, when filling the material, the powder material in the material box may be unevenly distributed, which will result in some mold grooves in the female mold not being completely filled. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

Reinforcing plates 23 are set on both sides of the guide plate 4 to ensure the structural strength and stability of the guide plate 4. A push rod 5 is set on the upper part of the guide plate 4 near the female mold mounting groove 3. The push rod 5 is parallel to the upper surface of the workbench 1.

[0030] The cylinder 6 is mounted on the upper surface of the workbench 1 via a bracket, and the cylinder 6 and the female mold mounting groove 3 are respectively located at both ends of the guide plate 4;

[0031] The material box 7 is movably mounted on the upper surface of the workbench 1. One end of the material box 7 is connected to the piston rod of the cylinder 6. The guide plate 4 is provided with several first guide sleeves 18. The material box 7 is provided with several transverse guide rods 19 near the guide plate 4. The transverse guide rods 19 correspond one-to-one with the first guide sleeves 18 and guide and cooperate to ensure the stability of the material box 7 and ensure that the bottom of the material box 7 is in close contact with the workbench 1. The guide plate 4 is provided with a second guide sleeve 20. The piston rod of the cylinder 6 is guided and cooperates with the second guide sleeve 20. The piston rod of the cylinder 6 is connected to the connecting sleeve 21. The connecting sleeve 21 is located at one end of the flange 22. The flange 22 is connected to the side of the material box 7 by bolts to ensure the stability of the piston rod of the cylinder 6, thereby further ensuring the stability of the material box 7. The material box 7 is provided with a through hole near the guide plate 4. A tapered guide sleeve 8 is provided at the outer end of the material box 7. The top rod 5 cooperates with the tapered guide sleeve 8. A through hole is opened at the end of the material box 7 away from the guide plate 4, and a limiting cylinder 9 is provided at the outer end of the through hole. An upper guide rod 10 and a lower guide rod 11 are provided inside the material box 7. The lower guide rod 11 is supported in the limiting cylinder 9 at the end away from the guide plate 4. A limiting plate 24 is provided at the end of the limiting cylinder 9 away from the material box 7. An annular limiting seat 25 is provided on the inner side of the limiting plate 24. The outer end of the lower guide rod 11 is connected to the annular limiting seat 25 to realize the installation of the lower guide rod 11. A triangular baffle 17 is provided inside the material box 7 and at the upper end of the upper guide rod 10. By setting the triangular baffle 17, when adding powder materials, the materials are prevented from directly contacting the upper guide rod 10, the lower guide rod 11 and the spring 16, ensuring the smoothness of the claw scraper 12 when sliding.

[0032] The scraping mechanism includes a claw-shaped scraper 12, an upper connecting plate 13, a lower connecting plate 14, and a slider 15. There are at least two claw-shaped scraper 12s, which are connected to each other through the upper connecting plate 13 and the lower connecting plate 14. The upper part of the claw-shaped scraper 12 is slidably engaged with the lower guide rod 11. The upper surface of the upper connecting plate 13 is slidably engaged with the upper guide rod 10 through the slider 15. A spring 16 is sleeved on the end of the lower guide rod 11 away from the guide plate 4. The spring 16 is supported on the outer end of a corresponding claw-shaped scraper 12.

[0033] Installation method and operating principle: Install cylinder 6 and guide plate 4 on the upper surface of workbench 1, and make the piston rod of cylinder 6 pass through the second guide sleeve 20 of guide plate 4, and fasten flange 22 to piston rod of cylinder 6 through connecting sleeve 21 and bolts. Connect two or more claw-shaped scraper plates 12 via an upper connecting plate 13 and a lower connecting plate 14. Connect the slider 15 on the upper surface of the upper connecting plate 13 to the upper guide rod 10. Place the claw-shaped scraper plates 12 and the upper guide rod 10 into the material box 7, and connect both ends of the upper guide rod 10 to both ends of the material box 7. Then, insert the lower guide rod 11 into the material box 7 from one end of the limiting cylinder 9, while passing the lower guide rod 11 through the upper part of the claw-shaped scraper plates 12. Connect one end of the upper guide rod 10 to the inner wall of the material box 7. Next, put the spring 16 on the outer end of the lower guide rod 11 and press the spring 16 into the limiting cylinder 9. Install the limiting plate 24 on the outer end of the limiting cylinder 9, and connect the outer end of the lower guide rod 11 with the annular limiting seat 25 inside the limiting plate 24. Finally, fasten the material box 7 to the flange 22 to complete the installation. Before use, install the female mold in the female mold mounting groove 3. During operation, the material box 7 retracts via the cylinder 6, and the powder falls into the material box 7 through the hopper, which is mounted above the worktable 1 via a frame. At this time, the push rod 5 passes through the conical guide sleeve 8 and abuts against the upper connecting plate 13 near the guide plate 4. The claw-shaped scraper 12 moves away from the guide plate 4 within the material box 7. The spring 16 is in a contracted state. When the material box 7 is pushed forward by the cylinder 6, the claw-shaped scraper 12 moves away from the limiting cylinder 9 along the upper guide rod 10 and lower guide rod 11 due to the thrust of the spring 16. When the material box 7 passes the female mold, the powder material falls into the female mold and is then pressed and shaped by the upper mold of the powder forming machine. When the material box 7 retracts, the push rod 5 passes through the conical guide sleeve 8 again and abuts against the upper connecting plate 13. The claw-shaped scraper 12 moves towards the limiting cylinder 9 within the material box 7, thereby scraping the powder material inside the material box 7. This utility model has a reasonable structure. The material box 7 is provided with an upper guide rod 10 and a lower guide rod 11. The upper part of the claw-shaped scraper 12 is slidably engaged with the lower guide rod 11, and the lower guide rod 11 is provided with a spring 16 to support the claw-shaped scraper 12. The guide plate 4 is provided with a top rod 5. When the material box 7 retracts, the top rod 5 is inserted into the material box 7 and abuts against the upper connecting plate 13, so that the claw-shaped scraper 12 can move relative to the material box 7. Thus, each time it retracts, the powder material in the material box 7 can be scraped and leveled by the claw-shaped scraper 12, avoiding molding failure due to uneven distribution of powder material during the filling process of the material box 7. Moreover, this structure is a purely mechanical structure, which does not require other additional driving devices, thus saving costs.
