Description

Technical Field

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

[0002] Magnetic powder pressing refers to a process method for manufacturing magnetic components, which is usually used to manufacture parts of magnetic materials, such as magnets, inductors, etc. In this process, magnetic powder is usually mixed with an adhesive and pressed into the required shape under high pressure. This method is usually used to produce magnetic materials that require specific shapes and properties because it can achieve high precision and complex shapes.

[0003] Currently, a magnetic powder pressing die is used in the pressing process. After the existing magnetic powder pressing die finishes pressing, the density of the magnetic material cannot meet the product requirements. Therefore, a new pressing die is needed to improve the density of the magnetic material after pressing to meet the required performance of the product. Summary of the Invention

[0004] The problem to be solved by the present utility model is: to provide a magnetic powder secondary pressing die, which can solve the problem that the density of the magnetic material after pressing by the existing magnetic powder pressing die cannot meet the product requirements.

[0005] The technical solution adopted by the present utility model to solve the above problems is: a magnetic powder secondary pressing die, including two charging disks. Two relatively arranged magnetic conduction plates are arranged between the two charging disks. A die body is arranged between the two magnetic conduction plates. A plurality of die cavities are arranged inside the die body. A push plate is arranged between the magnetic conduction plate and the charging disk. Pressing rods with the same number as the die cavities are fixedly connected to the push plate. An elastic component is arranged between the push plate and the magnetic conduction plate. The elastic component drives the push plate to move until one side surface of the push plate abuts against one side surface of the charging disk, so that one end of the pressing rod retracts to be flush with the die cavity surface; a driving group is installed on the magnetic conduction plate, and the driving group is used to drive the push plate to move towards the die body direction, so that one end of the pressing rod is inserted into the die cavity.

[0006] The elastic component drives the push plate to move until one side surface of the push plate abuts against one side surface of the charging disk, so that one ends of two relatively arranged pressing rods located on both sides of the die cavity retract to be flush with the die cavity surface, forming a larger die cavity volume to accommodate more magnetic powder. Then, the driving group drives the two pressing rods located on both sides of the die cavity to relatively insert into the die cavity, so that the volume inside the die cavity becomes smaller, thereby increasing the magnetic powder density in the die cavity, and solving the problem that the density of the magnetic material after pressing by the existing magnetic powder pressing die cannot meet the product requirements.

[0007] Preferably, two sliding grooves are opened on the magnetic conduction plate along the direction towards the die body. Hanging platforms are arranged on both sides of the push plate, and the two hanging platforms are inserted into the two sliding grooves.

[0008] Preferably, the driving group includes four clamping blocks and four cylinders mounted on the magnetic conductive plate. The end of the clamping block that is inserted is provided with an inclined surface facing one side of the mold body. Clamping grooves are formed on both sides of the push plate at the positions of the two hanging platforms. The four cylinders respectively drive the tapered surfaces of the four clamping blocks to abut against the sides facing the mold body in the four clamping grooves, and the push plate moves towards the mold body so that one end of the pressure rod is inserted into the mold cavity.

[0009] Preferably, the height of the inclined surface gradually increases in the direction towards the mold body, and the difference between the lowest point and the highest point of the inclined surface in the direction towards the mold body is greater than or equal to the depth at which one end of the pressure rod is inserted into the mold cavity.

[0010] Preferably, the elastic component includes four springs, and the four springs are symmetrically arranged up, down, left, and right along the center point of the push plate. Description of the Drawings

[0020] The following further describes the embodiments of the present invention with reference to the drawings.

[0021] Please refer to Figure 1 , this magnetic powder secondary molding die includes the following main components: There is a magnetic charging disk 1 on each side of the die, which is used to provide a magnetic field or perform magnetic treatment. Two magnetic conductive plates 4 are arranged opposite to each other between the two magnetic charging disks 1. The die body 5 is located between the two magnetic conductive plates 4 and is internally provided with a number of mold cavities 5.1 for forming the target shape of the molding.

[0022] Please refer to Figure 2 , the magnetic conductive plate 4 is provided with two sliding grooves 4.1 along the direction towards the die body 5. Please refer toFigure 3 , the hanging platform 2.2 is located on both sides of the push plate 2 and is inserted into the sliding groove 4.1 of the magnetic conductive plate 4 for supporting and guiding the movement of the push plate 2.

[0023] Please refer to Figure 4 , the pressure rod 2.1 is fixed on the push plate 2, and the quantity is the same as that of the mold cavities 5.1, and is used to apply pressure to the workpiece when the mold is closed. The elastic component 3 includes four springs 3.1, which are symmetrically arranged up, down, left and right along the center point of the push plate 2. The push plate 2 is located between the magnetic conductive plate 4 and the charging disk 1, and these springs 3.1 drive the push plate 2 to move until one side of the push plate 2 abuts against one side of the charging disk 1, so that one end of the pressure rod 2.1 retracts to be flush with the surface of the mold cavity 5.1.

[0024] Please refer to Figure 5 , the driving group 6 is installed on the magnetic conductive plate 4 and includes four clamping blocks 6.1 and four cylinders 6.2. The end of the clamping block 6.1 inserted is provided with an inclined surface 6.1.1 facing one side of the mold body 5, and clamping grooves 2.3 are provided on both sides of the push plate 2 where the two hanging platforms 2.2 are located.
