[0052] For example, see Figure 1-13 , the present invention provides the following technical solutions:

[0053] A forming mold for magnetic material processing, specifically, comprises a mold assembly 1, wherein a magnetic flux assembly 2 is sleeved and fixed on the top of the mold assembly 1; the mold assembly 1 comprises a lower mold part 3, an upper mold part 4 slidingly fitted on the lower mold part 3, and a demolding part 5 slidingly fitted on the lower mold part 3, and the demolding part 5 is located below the lower mold part 3; the lower mold part 3 comprises a lower mold 301, a molding groove 302 is provided on the top of the lower mold 301, two symmetrical guide holes 303 are provided through the bottom of the molding groove 302, and a plurality of guide slide bars 304 are fixed on the top of the lower mold 301; the upper mold part 4 comprises an upper mold 401 slidingly fitted on the plurality of guide slide bars 304, an installation cavity 402 is provided inside the upper mold 401, a pressing frame 403 adapted to the molding groove 302 is embedded in the bottom of the installation cavity 402, and the upper mold 4 A moving frame 404 is fixed to the outer surface of 01, and extension plates 405 are fixed to the two outer side surfaces of the moving frame 404, and an arc-shaped hook plate 406 is fixed to one side of the extension plate 405; the demolding part 5 includes two sliding rods 501 that are respectively slidably matched inside the two guide holes 303, a displacement frame 502 is fixed to the bottom of the two sliding rods 501, and an ejection plate 503 located inside the molding groove 302 is fixed to the top of the two sliding rods 501, and two return springs 504 that are respectively sleeved and matched on the two sliding rods 501 are fixed between the top of the displacement frame 502 and the bottom of the lower mold 301, and hinge seats 505 are fixed to the two inner side surfaces of the displacement frame 502, and pressure plates 506 that are compatible with the arc-shaped hook plates 406 are hingedly matched inside the two hinge seats 505, and a number of arc springs 507 are fixed between the pressure plates 506 and the displacement frame 502.

[0054] The specific application of this embodiment 1 is:

[0055] During the process of pressing and molding the magnetic material powder, the displacement frame 502 is in the initial position (when the displacement frame 502 is in the initial position, the ejector plate 503 fixed on the top of the sliding rod 501 is located inside the molding groove 302, and at this time, the bottom of the ejector plate 503 and the inner bottom of the molding groove 302 are in a mutually fitting state), and later when the magnetic material powder placed inside the molding groove 302 is pressed and molded, the moving frame 404 descends, driving the upper mold 401 to descend, and when the upper mold 401 descends, the inner bottom of the pressing frame 403 gradually approaches the magnetic material powder placed inside the molding groove 302, and the pressing and molding operation is performed on the magnetic material powder located inside the molding groove 302 through the pressing frame 403, so as to form the required molded magnetic material;

[0056] When the upper mold 401 is lowered, the outer wall of the extension plate 405 fixed on the two outer sides of the movable frame 404 and the arc-shaped hook plate 406 fixed on one side of the extension plate 405 will gradually approach one side of the pressure plate 506, and as the movable frame 404 continues to descend, a downward pressure is generated on the pressure plate 506 hinged and rotated inside the hinge seat 505, thereby synchronously squeezing a plurality of arc springs 507 fixedly connected between the pressure plate 506 and the displacement frame 502, so that the plurality of arc springs 507 are compressed, until the extension plate 405 fixed on the two outer sides of the movable frame 404 and the arc-shaped hook plate 406 fixed on one side of the extension plate 405 move to the bottom of the pressure plate 506, the magnetic material powder pressing molding process inside the molding groove 302 is completed, and the compressed plurality of arc springs 507 synchronously begin to recover under their own elasticity. The pressing plate 506 is then retracted to the left of the hinge 505, and the pressing plate 506 is then retracted to the right of the hinge 505.

[0057] When the auxiliary demoulding operation is performed later, the movable frame 404 rises, and thereby drives the upper mold 401 to rise. When the upper mold 401 rises, the bottom of its pressing frame 403 gradually moves away from the magnetic material that has been pressed and formed inside the molding groove 302. At this time, the upper mold 401 continues to rise, and under the effect of one end of the pressing plate 506 and the inner wall of the arc-shaped hook plate 406 being in contact with each other and temporarily fixed, the displacement frame 502 is synchronously driven to rise, so that the two return springs 504 fixedly connected between the displacement frame 502 and the lower mold 301 are synchronously compressed (when the magnetic material needs to be continuously pressed and formed later, one end of the pressing plate 506 and the inner wall of the arc-shaped hook plate 406 are in contact with each other and the temporary fixing effect disappears. At this time, under the effect of the elastic restoring force of the two return springs 504, the ejection plate 503 is restored. The two sliding rods 501 are respectively moved upward inside the two guide holes 303, so that the ejector plate 503 fixed at the top of the two sliding rods 501 is synchronously moved upward inside the molding groove 302, so as to assist in demolding the pressed magnetic material. As the upper mold 401 continues to rise, the bottom of the pressing frame 403 begins to generate a magnetic field under the action of the electric current, which assists in the adsorption of the pressed magnetic material, thereby improving the demolding efficiency between the already formed magnetic material and the molding groove 302, and avoiding the need for additional tools to demold the already processed magnetic material during the later stage of auxiliary demolding. The entire process can assist the ejector plate 503 to demold the already pressed magnetic material through the existing structure in the mold, thereby increasing the effect of auxiliary demolding.

Two sets of rectangular connecting plates 207 are respectively located inside the two vertical grooves 307, and latch shafts 308 are fixed inside the two vertical grooves 307, and the latch shafts 308 are fixedly connected to the pin holes 208; a cross groove 408 is penetrated on the top of the upper mold 401 to slide with the cross plate 206; a plurality of electromagnetic coils 409 are electrically connected in series at the bottom of the pressing frame 403 through wires; a plurality of magnetic bars 209 are fixed at the bottom of the cross plate 206, which slide and fit inside the electromagnetic coils 409;An electromagnetic switch 410 is provided on an outer side of the upper mold 401 below the moving frame 404, and the electromagnetic switch 410 is electrically connected to a plurality of electromagnetic coils 409 through a wire; Z-shaped support legs 309 are fixed to opposite sides of the lower mold 301 below the feed inclined frame 305, and a controller is fixed to one side of the Z-shaped support legs 309, and the controller is respectively connected to the first motor 509, the second motor 517, the telescopic cylinder 204, and the electromagnetic switch 410 through an external power supply. ;

[0059] The specific application of this second embodiment is:

[0060] During the use of this mold, the electromagnetic switch 410 is started by the controller (the control process of the controller is specifically implemented through the PCL control panel set inside it, which is a prior art and will not be elaborated on here). At this time, the electromagnetic coils 409 at the bottom of the pressing frame 403 that are electrically connected in series through wires begin to pass current. In the subsequent process of pressing and molding the magnetic powder, the telescopic cylinder 204 is started to extend through the controller control. At this time, the connecting flange 205 fixedly connected to its telescopic end is synchronously lowered, driving the movable frame 404 fixed on the connecting flange 205 to synchronously lower, so that the entire upper mold 401 is lowered. When the upper mold 401 is lowered, the electromagnetic coils 409 at the bottom of the pressing frame 403 that are electrically connected in series through wires are synchronously lowered, and gradually detached from the outer peripheral side of the magnetic rod 209. At this time, the magnetic force on the magnetic rods 209 begins to gradually disappear until the magnetic rods 209 set at the bottom of the pressing frame 403 are After the electromagnetic coils 409 are completely separated from the magnetic rods 209, the magnetic material powder is transported from the inlet ends of the two feed inclined frames 305 through the external transmission device, so that the magnetic material powder on the external transmission device falls into the molding groove 302 (the external transmission device is a prior art, which can be a conveyor for conveying powder, which is not shown in the figure and will not be elaborated on here). Subsequently, the telescopic cylinder 204 continues to extend, and its pressing frame 403 continues to descend as the upper mold 401 descends, and finally enters the molding groove 302, so as to perform a pressing and molding operation on the magnetic material powder inside the molding groove 302 (the shapes of the molding groove 302 and the pressing frame 403 can be adaptively changed according to the specific magnetic product to be processed), so as to realize the processing and molding operation of the magnetic material in the whole process, and avoid the magnetic force existing on the end faces of the magnetic rods 209 in the later pressing process to produce an adsorption force on the magnetic material powder inside the molding groove 302, which affects the later pressing and molding process;

[0061] When assisting demoulding of the pressed magnetic material at a later stage, the telescopic cylinder 204 begins to contract. At this time, the connecting flange 205 fixedly connected to the telescopic end thereof rises synchronously, driving the moving frame 404 fixed on the connecting flange 205 to rise synchronously. When the upper mold 401 rises, the inner bottom of the pressing frame 403 thereof, which is electrically connected in series through the wires, rises synchronously, and gradually sleeves onto the outer peripheral side of the magnetic rod 209. At this time, under the action of the electric current, the magnetic force on the magnetic rods 209 begins to assist the adsorption and demoulding operation of the formed magnetic material.

[0062] During the pressing and forming process of the magnetic material powder, the controller controls the telescopic cylinder 204 to start the extension while the mobile frame 404 fixed to the telescopic end of the telescopic cylinder 204 is synchronously lowered. At this time, the extension plate 405 fixed to the two outer sides of the mobile frame 404 and the arc-shaped hook plate 406 fixed to one side of the extension plate 405 will fit with one end of the pressing plate 506 until the inner wall of the arc-shaped hook plate 406 fits with one end of the pressing plate 506. The processing and pressing process of the magnetic material is completed. At this time, the controller controls the second motor 517 to start the cam 518 fixed to the output shaft of the second motor 517 to rotate, thereby squeezing the rectangular moving frame 520 to drive the displacement frame 502 The plug-in cross bar 519 fixed on an outer side surface synchronously slides on the side surface of the displacement frame 502, so that the elastic spring 521 fixedly connected between the rectangular moving frame 520 and the displacement frame 502 is compressed, thereby driving one end of the plug-in cross bar 519 to slowly approach the inside of the plug-in hole 523 opened on one side of the ear plate 522, until one end of the plug-in cross bar 519 is plugged and fixed with the plug-in hole 523, and then the second motor 517 is turned off by the controller, so as to ensure that the inner wall of the arc hook plate 406 and one end of the pressing plate 506 are in a state of mutual contact, so as to prevent the arc hook plate 406 and the pressing plate 506 from falling off when the magnetic material that has been pressed and formed is demolded later, so as to avoid affecting the auxiliary demolding process later;

[0063] After one end of the above-mentioned plug-in crossbar 519 is plugged and fixed with the plug-in hole 523, the magnetic material powder completes the pressing and forming process. At this time, the controller controls the telescopic cylinder 204 to contract again, driving the entire upper mold 401 to rise synchronously, thereby synchronously driving the displacement frame 502 to rise through the mutual adhesion between the inner wall of the arc-shaped hook plate 406 and one end of the pressure plate 506, and then assisting the demoulding operation of the magnetic material that has been pressed and formed;

[0064] After the above-mentioned pressing and auxiliary demoulding operations are completed, in order to facilitate the subsequent continuous pressing and demoulding operations, the second motor 517 is started again through the controller control, so that the cam 518 fixed to the output shaft of the second motor 517 rotates, so that the squeezing process of the cam 518 on the rectangular moving frame 520 gradually disappears, and thereby, through the elastic force of the compressed elastic spring 521, the plug-in cross bar 519 fixed to an outer side surface of the displacement frame 502 is driven to gradually slide out from the plug-in hole 523 opened on one side of the ear plate 522, until one end of the plug-in cross bar 519 is completely separated from the plug-in hole 523, and then the second motor 517 is turned off again through the controller control, and then, the controller is controlled The first motor 509 is started, and the winding roller 510 fixed to the output shaft of the first motor 509 is driven to rotate synchronously, and the traction rope 516 arranged between the winding roller 510 and the wiring shaft 515 is driven to pull synchronously inside the wire perforation 514 and the U-shaped tube 512, and finally wound around the peripheral side of the winding roller 510, so that the pressure plate 506 is flipped upward, thereby driving one end of the pressure plate 506 to gradually separate from the inner wall of the arc-shaped hook plate 406, until one end of the pressure plate 506 is completely separated from the inner wall of the arc-shaped hook plate 406, and the displacement frame 502 returns to its initial position, and then the above steps are repeated to continuously press and mold the magnetic powder and assist in demolding.
