[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in one embodiment of the present invention, a ferrite magnet pressing device includes a frame 1, a pressing mold 2, and a demolding component 3. The pressing mold 2 is placed on the base plate 101 of the frame 1, and the base plate 101 serves as a support for the pressing mold 2, ensuring stable installation and use. The pressing mold 2 consists of a bottom mold 201 and a pressure plate 202 that cooperate with each other. The pressure plate 202 is fixedly connected to the movable end of the hydraulic rod 103, facilitating the hydraulic rod 103 to drive the pressure plate 202 to move up and down, completing the pressing process of the material placed in the bottom mold 201. The ejector plate 301 of the demolding component 3 is placed in the bottom mold 201, and the ejector plate 301 is used to push out the pressed workpiece from the bottom mold 201, completing the demolding operation. The ejector rod 302 at the lower part of the ejector plate 301 passes through the bottom mold 201 and the base plate 101 in sequence, and is fixedly connected to the lower end of the connecting rod 303. The connecting rod 303 is detachably connected to the lower end of the movable rod 305 through a pin 304. Next, the upper end of the movable rod 305 passes through the base plate 101 and is fixedly connected to the movable end of the hydraulic rod 103 via the connecting rod 306. During use, as the hydraulic rod 103 drives the pressure plate 202 to move downward, the movable rod 305 moves downward along with the hydraulic rod 103 via the connecting rod 306, causing the lower end of the movable rod 305 to abut against the connecting rod 303. Then, a pin 304 connects the lower end of the movable rod 305 to the connecting rod 303. The pressure plate 202 then completes the connection. After pressing, the hydraulic rod 103 drives the pressure plate 202 to move upward and reset, and at the same time drives the movable rod 305 to move upward as well. When the movable rod 305 moves upward, it drives the ejector plate 301 to move upward through the connecting rod 303 and the ejector rod 302. The upward movement of the ejector plate 301 pushes out the pressed workpiece in the bottom mold 201, thereby completing the demolding operation. Finally, the pin 304 is pulled out, the connection between the movable rod 305 and the connecting rod 303 is removed, and the ejector plate 301 is reset.

[0022] like Figure 1 and Figure 3As shown, in some embodiments, the bottom mold 201 is provided with a pressing cavity 2011 for pressing the workpiece into the required shape, thus completing the pressing process of the workpiece. A recessed groove 2012 on the inner wall of the bottom of the bottom mold 201 communicates with the pressing cavity 2011, facilitating the stable placement of the ejector plate 301 into the recessed groove 2012 and ensuring smooth cooperation between the ejector plate 301 and the bottom mold 201. An insertion hole 2013 for slidingly inserting the ejector rod 302 is provided in the recessed groove 2012, facilitating the sliding of the ejector rod 302 within the insertion hole 2013, thereby carrying... The ejector plate 301 moves up and down, and the edge of the pressure plate 202 on the upper part of the bottom mold 201 extends downward to form an annular lip plate. The annular lip plate is set to cooperate with the bottom mold 201 to ensure that the pressure plate 202 is smoothly pressed onto the bottom mold 201 during the pressing process, thereby improving the smoothness of the pressing process. In addition, a connecting sleeve 2021 is provided at the middle position of the upper part of the pressure plate 202 to fix the movable end of the hydraulic rod 103, and to stably connect the pressure plate 202 to the hydraulic rod 103, ensuring that the hydraulic rod 103 stably drives the pressure plate 202 to move up and down.

[0023] like Figure 1 and Figure 4 As shown, in some embodiments, the ejector plate 301 is configured to cooperate with the recess 2012 in the bottom mold 201. The lower end of the ejector rod 302 at the bottom of the ejector plate 301 is fixedly connected to one end of the connecting rod 303, and the other end of the connecting rod 303 is provided with a connecting lug 3031. The connecting collar 3051 at the lower end of the movable rod 305 is configured to cooperate with the connecting lug 3031, and the pin 304 is slidably inserted into the connecting lug 3031 and the connecting collar 3051. By inserting the pin 304 between the connecting lug 3031 and the connecting collar 3051, a quick connection between the movable rod 305 and the connecting rod 303 is achieved, improving the convenience of operation. The upper end of the movable rod 305 passes through the through-hole opened on the bottom plate 101. Hole 1012 is inserted into the plug sleeve 3061 at one end of the connecting rod 306. The movable end of the limit bolt connected to one side of the plug sleeve 3061 abuts against the movable rod 305, ensuring that the movable rod 305 slides smoothly on the base plate 101. At the same time, the plug sleeve 3061 and the limit bolt are used to stably connect the movable rod 305 to one end of the connecting rod 306, achieving a stable connection between the two. The other end of the connecting rod 306 is fixedly connected to a semi-annular second fixing sleeve 3062. The second fixing sleeves 3062 are fixedly connected to each other by bolts to form a ring. The ring is set to cooperate with the movable end of the hydraulic rod 103. The second fixing sleeve 3062 is used to stably connect the connecting rod 306 to the hydraulic rod 103.

[0024] like Figure 1 and Figure 2As shown, in some embodiments, a limiting ring 1011 is provided on the upper part of the base plate 101. The limiting ring 1011 is sleeved on the outer bottom of the bottom mold 201 to ensure the stability of the bottom mold 201 placed on the base plate 101 and to ensure smooth pressing. The through holes 1012 opened in the inner area of ​​the limiting ring 1011 on the base plate 101 correspond one-to-one with the insertion holes 2013 opened on the bottom mold 201 to ensure that the push rod 302 slides smoothly on the base plate 101 and the bottom mold 201. The lower end of the mounting frame 102 is fixedly connected to a bolt seat 1022. The bolt seat 1022 is fixedly connected to the base plate 101 by bolts, which facilitates the stable connection of the mounting frame 102 to the base plate 101. On the base plate 101, a stable connection between the two is achieved. The upper end of the mounting frame 102 is bent, and a reinforcing rod 1023 is fixedly connected at the bent part to improve the strength of the mounting frame 102. The upper end of the mounting frame 102 is fixedly connected to a first fixing sleeve 1021, which is composed of two semi-circular arc plates. The connecting plates at both ends of the arc plates are fixedly connected by bolts. One of the arc plates is fixedly connected to the end of the mounting frame 102. The first fixing sleeve 1021 is fitted onto the hydraulic rod 103. The hydraulic rod 103 is stably connected to the mounting frame 102 by the first fixing sleeve 1021 to ensure the stable use of the hydraulic rod 103.
