6 descends, the die 6 descends to drive the connecting plate 7 to descend to drive the vertical rod 28 to drive the plug block 29 to descend, the die 6 compresses the first spring 5 to deform the first spring to generate acting force, the first spring 6 is contacted with the support plate to drive the support plate to descend along with the descending of the die 6, so that the support rod 23 and the outer rod 20 are driven to descend along with the descending of the die to stretch the third spring 22 to deform the third spring to generate acting force, when the die 6 descends to contact the connecting plate 7 and the support plate 25, the powder in the die 6 is fully injected, the blanking pipes 27 are sealed by the plug block 29, so that the, starting the air cylinder 8 to enable the air cylinder rod to extend to drive the pressing plate 9 and the driving plate 10 to descend, driving the vertical plate 11 and the inner rod 19 to descend by the driving plate 10, descending the pressing block 21 to enable the stretching degree of the third spring 22 to be reduced, when the pressing block 21 moves to the middle position of the outer rod 20, enabling the third spring 22 to restore to the original state, enabling the third spring 22 to be compressed to deform to generate acting force along with the continuous descending of the inner rod 19 and the pressing block 21, driving the outer rod 20 to descend to enable the supporting plate and the supporting rod 23 to descend to enable the part, located in the mold 6, of the supporting rod 23 to be gradually reduced, in the process, enabling the vertical plate 11 to drive the convex block 12 to be in contact with the cross rod 16 to enable the cross rod 16 to be driven to move backwards to drive the ejector rod 14 and the pressing plate 17 to move along with the same, enabling the pressing plate 17 and the ejector rod 14 to move forwards to enable the ejector rod 14 to collide with the mold The mold 6 is continuously vibrated by the continuous contact and separation of the convex blocks 12 and the cross rods 16, so that the powder inside the mold 6 is vibrated, gaps caused by the support rods 23 are reserved at the centers of the powder in the mold 6 due to the movement of the support rods 23, the powder is filled in the gaps by the vibration caused to the powder, the influence of the reserved gaps on the molding of an object is avoided, the support plate is contacted with the stop block 24 along with the continuous movement of the cylinder 8, so that the support plate stops moving, the top ends of the support rods 23 are flush with the bottom wall of the mold 6 at the moment, the cylinder 8 continuously drives the press plate 9 to descend so that the press plate 9 extrudes the powder to form a molded part, the inner rod 19 and the press block 21 continue to compress the third spring 22 in the process, the cylinder 8 is started to shorten after the powder is extruded to drive the press plate 9 and the drive plate 10 to ascend, so that the press block 21 and the inner rod 19 are driven, with the continuous rising of the pressing block 21, the third spring 22 is stretched, when the pressing block 21 moves to contact with the top wall of the outer rod 20, the outer rod 20 is driven to rise, so that the support plate and the support rod 23 are driven to rise, so that the support rod 23 supports the formed part inside upwards, so that the formed part is driven to rise, the weight of the mold 6 is instantly reduced as the formed part rises, at the moment, the first spring 5 releases acting force to drive the mold 6 to rise, so that the mold 6 contacts with the formed part again, finally, the mold 6 synchronously moves to keep the relative position with the support rod 23 when the support rod 23 moves, so that the top end of the support rod 23 is flush with the bottom wall of the mold 6, when the mold 6 moves to the highest position, the mold 6 cannot continuously move due to the limitation of the telescopic rod 4, at the support rod 23 continuously moves to drive the formed part inside to rise, so that the, finally, the top surface of the formed part leaks out of the mold 6, at this time, the two sides of the formed part are contacted with the bottom ends of the blanking pipes 27 at the two sides, so that the blanking pipes 27 are sealed, the mold 6 can drive the starting rod 31 to descend to be contacted with the switch 30 when descending, so that the starting rod 31 rotates upwards, when the starting rod 31 moves to the position below the switch 30, the starting rod 31 is reset due to gravity, when the mold 6 ascends, the starting rod 31 is contacted with the switch 30 again, at this time, the bottom end of the starting rod 31 is contacted with the bottom wall of the movable seat, so that the starting rod 31 cannot rotate downwards due to the collision between the bottom end of the starting rod 31 and the bottom wall of the movable seat, so that the starting rod 31 and the switch 30 slide relatively in the ascending process, so that the switch 30 is pressed, so that the electric push rod 322 and the motor 325 are started, the output shaft of the motor 325 rotates to drive the grinding roller 324, then the electric push rod 322 resets to reset the grinding roller 324, and the motor 325 is turned off after a set time, at this time, the formed part can be taken out, at this time, the sealing of the blanking pipe 27 is released, similarly, when the mold 6 ascends, the vertical rod 28 and the plug block 29 are driven to ascend, when the mold 6 ascends to the initial position, the plug block 29 leaves the blanking pipe 27 to open the blanking pipe, at this time, the powder inside enters the mold 6 through the blanking pipe 27 again, and automatic feeding and automatic material cutting are realized.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
