[0029] Embodiment 1:

[0030] A magnetic material processing and forming mold, comprising a bottom plate 1, the bottom surface of the bottom plate 1 is fixedly connected with support legs 2 near its four corners, the surface of the bottom plate 1 is symmetrically fixedly connected with support columns 5, the top of the support column 5 is fixedly connected with a top plate 3, the surface of the top plate 3 is fixedly installed with a telescopic cylinder 4, the telescopic end of the telescopic cylinder 4 is fixedly connected with a mounting plate 6, the bottom surface of the mounting plate 6 is provided with an upper mold 8, the bottom surface of the bottom plate 1 is fixedly connected with a protective box 11, the surface of the bottom plate 1 is provided with a lower mold 27, and the interior of the protective box 11 is provided with a clamping assembly for fixing the lower mold 27;

[0031] The clamping assembly includes a first rotating rod 18, a first gear 19, a slide rail 20, a rack 21, a vertical rod 22 and a clamping plate 23. The inner wall surface of the protection box 11 is rotatably connected to the first rotating rod 18, and the top end of the first rotating rod 18 is fixedly connected to the first gear 19. The inner surface of the protection box 11 is symmetrically fixedly connected to the slide rail 20, and the inner wall surface of each slide rail 20 is slidably connected to the rack 21. The two racks 21 are respectively meshed with the first gear 19. The surface of the rack 21 is fixedly connected to the vertical rod 22. The top end of the vertical rod 22 extends to the top of the bottom plate 1 and is fixedly connected to the clamping plate 23 arranged at the top of the bottom plate 1, which is used to clamp and fix the lower mold 27.

[0032] The two sides of the mounting plate 6 are slidably sleeved on the surface of the support column 5, which can limit the moving track of the mounting plate 6 and ensure that the mounting plate 6 does not deflect during the movement;

[0033] The surface of the mounting plate 6 is symmetrically provided with mounting holes 7, and the surface of the upper mold 8 is symmetrically fixedly connected with threaded columns 9, and the surface of the threaded columns 9 is threadedly sleeved with nuts 10, and the threaded columns 9 are inserted into the interior of the mounting holes 7. The upper mold 8 is connected to the mounting plate 6 through the mounting holes 7, the threaded columns 9 and the nuts 10. The threaded columns 9 are fixed to the surface of the mounting plate 6 by using the nuts 10, so that the upper mold 8 can be disassembled and assembled, and the upper mold 8 and the lower mold 27 can be replaced, so that the upper mold 8 and the lower mold 27 can match each other to ensure the subsequent molding quality;

[0034] The inner wall of the protection box 11 is symmetrically fixedly connected with a first fixed plate 12, and a second rotating rod 13 is rotatably connected between the two first fixed plates 12. A worm 14 is fixedly sleeved on the surface of the second rotating rod 13, and a worm wheel 17 is fixedly sleeved on the surface of the first rotating rod 18. The worm 14 and the worm wheel 17 are meshed and connected, which is convenient for driving the second rotating rod 13 to rotate, thereby realizing the disassembly of the lower mold 27;

[0035] The bottom surface of the clamping plate 23 is fixedly connected with a limit slide 25, and the surface of the bottom plate 1 is provided with a limit slide groove 29, and the limit slide 25 is inserted into the limit slide groove 29. The limit slide 25 and the bottom plate 1 are slidably connected, which can limit the moving track of the clamping plate 23, and ensure that the clamping plate 23 will not be skewed when sliding on the surface of the bottom plate 1;

[0036] The surface of the clamping plate 23 is equidistantly fixed with insertion rods 24, and the surface of the lower mold 27 is symmetrically provided with insertion holes 28, in which the insertion rods 24 are inserted. Through the mutual cooperation between the insertion rods 24 and the insertion holes 28, the lower mold 27 can be prevented from moving during the clamping process.

[0037] Embodiment 2:

[0038] Although the above technical solution uses the clamping assembly to disassemble and replace the lower mold, which is flexible and convenient to use, the hand wheel 15 is very likely to cause the lower mold 27 to be unreliably fixed due to misoperation by the user after the rotation is completed. Therefore, in this embodiment, one end of the second rotating rod 13 extends to the outside of the protection box 11 and is fixedly connected to the hand wheel 15 arranged on the outside of the protection box 11. The surface of the hand wheel 15 is threadedly connected to the limit bolt 16. The surface of the protection box 11 is provided with an annular friction groove 26. The limit bolt 16 can be placed in the annular friction groove 26, which can limit the rotation position of the hand wheel 15 and ensure that the lower mold 27 will not loosen during use;

[0039] Working principle: When using this molding die to mold magnetic materials, first select the upper mold 8 and the lower mold 27 of appropriate models according to the needs, and then install the upper mold 8 and the lower mold 27 respectively;

[0040] During installation, first install the upper mold 8, unscrew the nut 10 from the surface of the threaded column 9, and then insert the threaded column 9 into the corresponding mounting hole 7 on the surface of the mounting plate 6, so that the upper end of the threaded column 9 passes through the mounting plate 6, and then screw the nut 10 on the surface of the threaded column 9 that passes through, and tighten the nut 10, thereby completing the installation of the upper mold 8;

[0041] Then install the lower mold 27. First, rotate the limiting bolt 16 so that the limiting bolt 16 no longer conflicts with the annular friction groove 26. At this time, the limiting bolt 16 on the hand wheel 15 is released, and then the hand wheel 15 is rotated. The hand wheel 15 is used to drive the second rotating rod 13 to rotate. The second rotating rod 13 rotates and then drives the worm 14 to rotate. The worm 14 rotates and then drives the worm wheel 17 to rotate. The worm wheel 17 rotates and then drives the first rotating rod 18 to rotate. The first rotating rod 18 rotates and then drives the first gear 19 to rotate. The first gear 19 rotates and then drives the racks 21 on both sides to move away from each other, and then makes the clamping plates 23 on both sides move away from each other. Then place the lower mold 27 on the surface of the bottom plate 1, and then reverse the hand wheel 15. The reversal of the hand wheel 15 drives the second rotating rod 13 to reverse, and the second rotating rod 13 rotates. The rod 13 is reversed and then drives the worm 14 to reverse, the worm 14 is reversed and then drives the worm wheel 17 to reverse, the worm wheel 17 is reversed and then drives the first rotating rod 18 to reverse, the first rotating rod 18 is reversed and then drives the first gear 1 to reverse, the first gear 19 is reversed and then drives the racks 21 on both sides to approach each other, until the clamping plates 23 on both sides are about to approach the lower mold 27, the position of the lower mold 27 is manually adjusted, so that the insertion rod 24 on the surface of the clamping plate 23 on one side is inserted into the insertion hole 28 on one side of the lower mold 27, and then the hand wheel 15 is continuously rotated until the insertion rods 24 on both sides are inserted into the insertion hole 28, and the clamping plates 23 on both sides are tightly attached to the lower mold 27, and then the limiting bolt 16 is rotated so that the end of the limiting bolt 16 conflicts with the annular friction groove 26, and the hand wheel 15 is limited at this time;

[0042] After the upper mold 8 and the lower mold 27 are installed, the magnetic material can be molded. The magnetic material to be molded is placed in the lower mold 27, and then the telescopic cylinder 4 is started to move the mounting plate 6 downward, thereby making the upper mold 8 contact the lower mold 27 to complete the molding of the magnetic material. In the utility model, the upper mold 8 and the lower mold 27 can be disassembled, so that the mold can be replaced according to actual needs, and it is more flexible and convenient to use.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
