[0027] Working principle: During operation, when operation is required, first pour the magnetic material onto the push plug 43 inside the crucible 41, then place the crucible 41 inside the installation box 32, align the bottom end of the crucible 41 with the circular notch 321, and then power on the second motor 332 to start working. The second motor 322 drives the threaded rod 334 at the right end to rotate in the side inner groove 322 on the rear side of the installation box 32, and the threaded rod 334 rotates in the limiting sleeves 335 sleeved on both sides. The rotation of the threaded rod 334 can drive the two sets of threaded sleeves 336 in opposite directions in the center to move, and the movement of the threaded sleeves 336 can drive the arc-shaped clamping plate 337 fixed at the front end to move. The arc-shaped clamping plate 337 fixed at the front end The moving wheel 338 can move in the side inner groove 322 of the front end to synchronously move the two groups of arc clamping plates 337 inward to clamp the crucible 41.

When the transverse bevel gear 232 rotates one circle, it can engage the vertical bevel gear 231 on the outer side of the center of the rotating column 22 to rotate ninety degrees. When a group of crucibles 41 moves to the bottom end of the rear end hydraulic mechanism 6 under the rotation of the bottom end rotating column 22, the hydraulic cylinder 61 can be started to descend the crucible. The magnetic material in the crucible 41 is pressed and formed. When the hydraulic cylinder 61 descends, the fixed collar 621 fixed at the bottom end descends.

When the cross bar 622 descends, the main rack plate 71 fixed on the right side can be driven to descend. The main rack plate 71 descends to engage the fixed gear 721 at the front end to rotate. The rotation of the fixed gear 721 can drive the fixed shaft 722 to rotate. When the crucible 41 is clamped in the four groups of installation boxes 32, the fixed conveyor belt group 510 can be driven to rotate when the fixed shaft 722 rotates. The rotation of the conveyor belt group 510 is The transmission rod 58 can be driven to rotate between the fixed block 59 and the right wall of the placement box 21. The rotation of the transmission rod 58 can drive the first gear 57 fixed in the center to rotate. The rotation of the first gear 57 can mesh with the auxiliary rack plate 55 in the front sliding column 53 to rise. The rise of the auxiliary rack plate 55 can drive the sliding column 53 to rise in the hollow cylinder 51. The rising of the sliding column 53 can push the push plug 43 upward to the top of the crucible 41 through the circular notch 321 at the bottom of the installation box 32 through the protruding block 56 fixed at the top, so as to facilitate the removal of the material after the magnetic material is pressed and formed.
