[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-5 , a magnetic field molding machine with a self-cleaning function, including a frame 1, a molding die 3 is arranged inside the frame 1, and a placement frame 2 that is in contact with the molding die 3 and connected to the inner bottom wall of the frame 1. A first oil cylinder 4 is fixedly connected to the upper surface of the frame 1, and a cleaning mechanism 5 is connected to the first oil cylinder 4.

[0027] Refer to Figures 1 to 5 , the setting of the first oil cylinder 4 can facilitate the extrusion molding of the magnetic powder in the molding die 3, and through the mutual adaptation and connection of the placement frame 2 and the reserved holes in the molding die 3, it can facilitate the storage of the magnetic powder and the work of the lower driving device to push out the molded workpiece.

[0028] A second oil cylinder 6 is installed in the reserved groove at the lower part of the frame 1. The output end of the second oil cylinder 6 penetrates through the frame 1 and is directly below the reserved hole in the placement frame 2. By setting the second oil cylinder 6, the output end of the second oil cylinder 6 can pass through the placement frame 2 and be tightly attached to the reserved hole of the molding die 3, avoiding the dropping of the magnetic powder in the molding die 3.

[0029] And it is convenient to cooperate with the first oil cylinder 4 to press and mold the magnetic powder, and it is also convenient to push the workpiece out of the molding die 3 after the magnetic powder is pressed and molded, facilitating the removal of the workpiece.

[0030] Orientation electromagnetic rings 7 are inlaid on the outer surface of the frame 1 at two positions facing the molding die 3, and a handle 8 is connected to the orientation electromagnetic rings 7 and located outside the frame 1. By setting the handle 8, it can facilitate the adjustment of the expansion and contraction of the orientation electromagnetic rings 7, thereby adjusting the distance between the two orientation electromagnetic rings 7, and further adjusting the magnetic field strength during the processing of the magnetic powder.

[0031] The cleaning mechanism 5 includes a pressing plate 502 located inside the frame 1 and facing above the molding die 3, and a pressing rod 501 connected to the pressing plate 502 and fixedly connected to the output end of the first oil cylinder 4. The pressing plate 502 is used to press and mold the powder material in the molding die 3.

[0032] Refer to Figures 1 to 4, The setting of the cleaning mechanism 5 can facilitate the suction of magnetic residues scattered on the surface of the forming die 3 by the magnetic powder in the forming die 3 during pressing, thereby keeping the surface of the forming die 3 clean, avoiding the influence of residues on the subsequent workpiece pressing and forming effect, and facilitating the solution of the inconvenience during the cleaning by the staff.

[0033] The cleaning mechanism 5 includes a connecting ring 503 fixedly connected to the outer surface of the extrusion rod 501, and a plurality of extraction heads 504 embedded in the bottom surface of the connecting ring 503 and facing the upper surface of the forming die 3. By setting the sliding cylinder 505, it is convenient to suck the residues through subsequent components, and by the descent of the connecting ring 503 following the extrusion rod 501, the extraction heads 504 can synchronously descend to the upper part of the forming die 3, facilitating the suction and cleaning of the residues.

[0034] And the length of the extrusion rod 501 extending into the forming die 3 has a specific distance limit, which will not cause the situation that the extraction heads 504 and the forming die 3 are damaged by extrusion when the extrusion rod 501 descends into the forming die 3.

[0035] The cleaning mechanism 5 further includes an annular pipe 506 sleeved on the outer surface of the first oil cylinder 4, and a sliding cylinder 505 communicating with the annular pipe 506 and the extraction heads 504. By setting the sliding cylinder 505, it is convenient to slide at the frame 1, so that it can move synchronously with the descent of the extraction heads 504, and then the plurality of sliding cylinders 505 are connected through the annular pipe 506, facilitating the connection with subsequent components and greatly improving the practicality of the overall device.

[0036] The cleaning mechanism 5 further includes a blower 507 fixed on the upper surface of the frame 1, and a corrugated pipe 508 communicating with the output end of the blower 507 and the outer surface of the annular pipe 506. By setting the blower 507, the output end of the blower 507 sucks air into the annular pipe 506 through the corrugated pipe 508.

[0037] Thus, the residues on the surface of the forming die 3 are sucked through the annular pipe 506 and the extraction heads 504, facilitating the cleaning of the residues and reducing the workload and inconvenience of the staff.

[0038] A clamping and positioning assembly is provided outside the forming die 3. The clamping and positioning assembly is used to clamp the forming die 3 and move it to the reserved hole in the placement frame 2. By setting the clamping and positioning assembly, it is convenient to clamp, install and disassemble the forming die 3, so as to facilitate the quick installation or disassembly of the forming die 3 and reduce the complexity of the staff during the installation of the forming die 3.

[0039] The clamping and positioning assembly includes a connecting plate 9 connected to the placement frame 2. The clamping and positioning assembly further includes an electric push rod 10 fixedly connected to the connecting plate 9, and clamping blocks 11 connected to the output end of the electric push rod 10 and facing two directions of the forming die 3.

[0040] By setting the electric push rod 10, it is possible to facilitate the pushing or pulling of the clamping block 11 to clamp and fix the forming die 3, so as to facilitate the accurate connection of the material storage hole in the forming die 3 with the through hole in the placement frame 2, and further facilitate the positioning installation or disassembly of the forming die 3, greatly improving the convenience of installing or disassembling the forming die 3.

[0041] The clamping and positioning assembly further includes a slide bar 12 connected to the clamping block 11 and slidably matched with the connecting plate 9. A collection box 13 is fixedly connected to the outer surface of the frame 1. By setting the slide bar 12, the stability of the clamping block 11 during the clamping and positioning of the forming die 3 can be better improved, and the clamping and positioning effect on the forming die 3 can be greatly improved. The setting of the collection box 13 can facilitate the storage and placement of the pressed workpieces.

[0042] The specific implementation process of the present utility model is as follows: When compacting the magnetic powder, first, through the clamping and positioning assembly, by means of the electric push rod 10, the electric push rod 10 pushes the clamping block 11 to install and fix the forming die 3, so that the reserved hole in the forming die 3 is adapted and communicated with the reserved hole in the placement frame 2, and the output end of the second oil cylinder 6 can be closely attached to the inner wall of the reserved hole in the placement frame 2, and the magnetic field size of the orientation electromagnetic ring 7 for the magnetic powder in the forming die 3 can be adjusted through the handle 8 according to requirements.

[0043] At this time, pour the magnetic powder into the forming die 3. By starting the first oil cylinder 4, the output end of the first oil cylinder 4 pushes the extrusion rod 501 and the extrusion plate 502 to press down. And when the extrusion plate 502 presses the magnetic powder in the forming die 3, the connecting ring 503 and the extraction head 504 can be driven to descend synchronously by the extrusion rod 501. When the blower 507 is started, the extraction head 504 sucks the residues on the surface of the forming die 3, so as to clean the residues and avoid the residues affecting the subsequent forming of the workpiece. After the workpiece is formed, when the extrusion rod 501 and the output end of the second oil cylinder 6 are started simultaneously, the workpiece is pushed out of the forming die 3, and it is thus convenient for the staff to take out the workpiece.

[0044] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, are similarly included in the patent protection scope of the present utility model.
