When the connecting block 209 ascends, the limiting strip 208 and the rack 207 are driven to slide upwards on the base 201, the rack 207 is meshed with the third gear 206, so that the third gear 206 can rotate in a single direction, the third gear 206 rotates to drive the second rotating shaft 203 to rotate, the second rotating shaft 203 rotates to drive the first bevel gear 205 to rotate, the first bevel gear 205 rotates to drive the second bevel gear 229 to rotate, the second bevel gear 229 rotates to drive the screw 220 to rotate, the screw 220 rotates to drive the moving block 222 to be away from the chuck 219, the hopper 224 can deflect by utilizing the hinged connection of the moving block 222 and the first hinged seat 223 and the hinged connection of the second hinged seat 227 and the third hinged seat 228, and the casting liquid in the hopper 224 can flow out from the discharge port 225 and flows into the casting mold.

At this time, the driving wheel 119 drives the driven wheel 117 to rotate by using the belt 118, the driven wheel 117 rotates to drive the first rotating shaft 107 connected at the center thereof to rotate, and the symmetrical synchronizing wheels 108 are sleeved by using the synchronous belt 109, so that the symmetrical first rotating shafts 107 can rotate simultaneously.

The first rotating shaft 107 rotates to drive the worm 106 to rotate on the connecting support 105, the worm 106 rotates to drive the worm wheel 110 to rotate, the worm wheel 110 rotates to drive the rotating rod 111 at the center of the worm wheel 110 to rotate at the center of the symmetrical fixed disk 112, the rotating rod 111 rotates to drive the rotating arm 113 to rotate circularly, the connecting arm 115 at the other end of the rotating arm 113 rotates on the fixed seat 116 and the cylinder 114 at one end of the rotating arm 113 along with the rotating rod and deflects, so that the connecting arm 115 can control the connecting support 105 to move in a reciprocating mode, a motor shell mold at the top end of the moving plate 103 between the symmetrical connecting supports 105 moves in a reciprocating mode, and casting liquid in the hopper 224 can uniformly fall into the mold to be cast.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
