A movable mounting seat 4 is fixed on the upper end face of the upper mold base 3, and a fixed box 5 is installed on both the left and right end faces of the movable mounting seat 4.

[0020] A drive motor 6 is fixed to the lower end face inside the fixed housing 5. A first rotating rod 7 is installed at the output end of the drive motor 6. A first transmission gear 14 is fixed to the outer side of the annular surface of the first rotating rod 7. A second transmission gear 9 is meshed with the first transmission gear 14. A second rotating rod 8 is installed on the inner side of the annular surface of the second transmission gear 9. A movable seat 10 is provided through the second rotating rod 8. A water-cutting cutter 13 extends through the interior of the movable mounting seat 4. A movable plate 11 is fixed to the upper end face of the water-cutting cutter 13. A return spring 12 is fixed between the movable plate 11 and the movable mounting seat 4. This design can automatically cut the water cut after die casting, improve the cutting efficiency, and realize fully automated production.

[0021] As the first embodiment of this utility model: an alloy die casting is die-cast between the upper mold base 3 and the lower mold base 2, and the movable mounting base 4 can be connected to an external driving device. This design allows the movable mounting base 4 to move up and down through the external driving device, so that the upper mold base 3 and the lower mold base 2 can die-cast the workpiece.

[0022] The specifications of the first transmission gear 14 match those of the second transmission gear 9, and the two can mesh and connect. The fixed housing 5 and the movable mounting base 4 both have movable holes inside. The inner diameter of the movable hole is equal to the outer diameter of the second rotating rod 8, and the two can mesh and connect. The outer surface of the second rotating rod 8 has an external thread, and the movable base 10 has a threaded hole inside. The outer diameter of the external thread is equal to the inner diameter of the threaded hole, and the two can mesh and connect. The movable base 10 is slidably connected to the inner wall of the movable mounting base 4. The movable base 10 has a trapezoidal structure, and one end of its inclined surface can mesh and connect with the movable plate 11. This design drives the first rotating rod 7 to rotate through the transmission motor 6, so that the first transmission gear 14 rotates and meshes with the second transmission gear 9, so that the second rotating rod 8 rotates. The external thread and the threaded hole can mesh and connect, so that the movable base 10 can move left and right, so that one end of the inclined surface of the movable base 10 can mesh and connect with the top of the movable plate 11, so that the movable plate 11 can move downward.

The return spring 12 can automatically return to the initial position after the water cut is cut off, which is convenient for the next cutting.

[0024] As a second embodiment of this utility model: the operator first connects the drive motor 6 to an external power supply and an external controller through wires. The external drive device can drive the movable mounting base 4 to move up and down, so that the upper mold base 3 and the lower mold base 2 can die-cast the workpiece. The cut-out generated after die-casting needs to be removed. The drive motor 6 drives the first rotating rod 7 to rotate, so that the first drive gear 14 rotates and meshes with the second drive gear 9, so that the second rotating rod 8 rotates. The external thread and the threaded hole can mesh and rotate, so that the movable base 10 can move left and right, so that one end of the inclined surface of the movable base 10 is slidably connected to the top of the movable plate 11, so that the movable plate 11 can move downward, driving the water-cutting cutter 13 to move in the movable groove, so that it moves downward to remove the cut-out of the die-casting part. The return spring 12 can automatically return to the initial position after the cut-out is removed, so as to facilitate the next cut.
