[0002] Tensioner blocks are mechanical components mainly used to maintain the appropriate tension of transmission components in mechanical systems, such as belts, chains, and ropes, ensuring that the transmission components always maintain the appropriate tightness so that the transmission components can effectively transmit power. Tensioner blocks are usually manufactured by pressing metal powder into the required shape through a mold and then sintering it.

[0003] When the existing mold is used for pressing, metal powder tends to fall onto the surface of the lower mold, which can cause the upper and lower molds to not close completely, affecting the pressing effect on the powder and impacting the quality of the product. This requires timely manual cleaning. Repeated cleaning not only reduces the production efficiency of the tensioning block but also easily creates safety hazards. Utility Model Content

[0029] Working principle: The lower mold 1 and upper mold 2 are installed on the machine. Starting the machine moves the upper mold 2 downwards, pressing the powder inside the upper mold 2 into shape via the telescopic cylinder 4. The downward movement of the upper mold 2 causes the lifting seat 12 to move downwards, causing the guide block 13 to move downwards along the guide groove 14. Under the action of the guide block 13 and the guide groove 14, the guide column 9 rotates, which in turn causes the cleaning plate 11 to rotate via the mounting ring 10, sweeping the powder on the surface of the lower mold 1 into the collection trough 7 and then into the collection box 16 for collection. After pressing, the upper mold 2 moves upwards, causing the lifting seat 12 to move upwards, thus moving the guide column 9 downwards under the action of the guide block 13 and the guide groove 14. The upper mold 2 rotates in the other direction, which in turn drives the cleaning plate 11 to rotate in the other direction through the mounting ring 10, sweeping the powder on the lower mold 1 into the collection groove 7 on the other side. This achieves the effect of cleaning the surface of the lower mold 1 by rotating the cleaning plate 11 through the up and down movement of the upper mold 2. At the same time, after moving upward on the upper mold 2, the telescopic cylinder 4 drives the demolding plate 5 to push out the product pressed and formed inside the mold cavity 3 to complete the demolding. The pressing blocks 20 on both sides of the collection groove 7 are pressed and the push plate 22 is moved by the second spring 19 to push the locking block 18 into the connecting rod 15, so that the locking block 18 is disengaged from the collection groove 7 and the fixing of the connecting rod 15 is released. Thus, the collection box 16 can be removed to process the collected powder.
