Description

Technical Field

[0001] The embodiments of the present application relate to the field of magnetic materials, and specifically to a cleaning mechanism for the upper die of a magnetic powder pressing die. Background Art

[0002] Magnetic powder pre-pressing refers to the process of mixing magnetic powder with other additives in a certain proportion during the manufacturing of magnetic components, and then putting them into a mold and applying a certain pressure for forming.

[0003] During the magnetic powder pre-pressing process, magnetic powder is likely to remain on the upper die of the magnetic powder pressing die. The remaining magnetic powder will become ineffective after a certain period of time, and then transfer to the products after pre-pressing and pressing, resulting in a decline in the performance of the final products. Therefore, a mechanism is needed to clean the magnetic powder remaining on the upper die to avoid transferring it to the products after multiple pre-pressings. Summary of the Invention

[0004] The problem to be solved by the present utility model is to provide a cleaning mechanism for the upper die of a magnetic powder pressing die, which can clean the magnetic powder remaining on the upper die, avoid transferring it to the products after multiple pre-pressings, and at the same time prevent the cleaned magnetic powder from scattering onto other mechanisms.

[0005] The technical solution adopted by the present utility model to solve the above problems is: a cleaning mechanism for the upper die of a magnetic powder pressing die, including a pressing frame. An upper die is arranged on the pressing frame. A cleaning mechanism is arranged below the upper die. The cleaning mechanism includes a brush head and a brush head drive. The brush head is located on one side of the upper die. Brush hairs are arranged on the brush head. The brush head drive is used to drive the brush hairs on the brush head to move back and forth from one side of the upper die to the other side of the upper die. A collection box is arranged below the brush head. The collection box has a collection cavity, and the collection cavity is used to collect the magnetic powder that falls by its own weight after being cleaned by the brush hairs.

[0006] This cleaning mechanism for the upper die of a magnetic powder pressing die drives the brush hairs on the brush head to move back and forth from one side of the upper die to the other side to clean the magnetic powder residue on the surface of the upper die, which can ensure the quality of the pressed products. It avoids the influence of magnetic powder residue on the appearance and performance of the products, improves the consistency and reliability of the products, and collects the magnetic powder that falls by its own weight after being cleaned by the brush hairs through the collection cavity.

[0007] Preferably, the brush hairs on the brush head are made of at least one of silicone, TPR, TPE, PVC or natural rubber.

[0008] Preferably, one end of a connecting rod is fixed on the collection box. A T-shaped connecting portion is arranged at the other end of the connecting rod. A T-shaped groove is arranged below the brush head, and the connecting portion is embedded in the T-shaped groove.

[0009] Preferably, the brush head drive is a cylinder, and the cylinder is installed on the press frame.

[0010] Preferably, a connecting block is provided between the output end of the cylinder and one side of the brush head. A first assembly groove is provided on one side of the connecting block, the output end of the cylinder is embedded in the first assembly groove, a second assembly groove is provided on the other side of the connecting block, and one side of the brush head is embedded in the second assembly groove.
