[0025] The mold part includes a lower mold 10 fixedly mounted on one side of the upper end of the base 1, and a No. 2 servo push cylinder 14 is arranged at the lower side of the lower mold 10. The No. 2 servo push cylinder 14 drives the ejector rod 12 and the ejector block 11 to eject the formed workpiece 43. The No. 2 servo push cylinder 14 is fixed on the base 1, and a bearing seat 13 is arranged directly below the lower mold 10. The bearing seat 13 is fixed to the output end of the No. 2 servo push cylinder 14, and the bearing seat 13 plays the role of bearing the ejector rod 12 and the ejector block 11. A plurality of ejector rods 12 are arranged in a circular array at the front end of the upper end of the bearing seat 13, and a plurality of ejector rods 12 are arranged at the rear end of the upper end of the bearing seat 13. Two ejector blocks 11 are symmetrically fixedly installed on the upper part, and the ejector rod 12 and the ejector block 11 both penetrate the lower end of the lower mold 10, and the ejector rod 12, the ejector block 11 and the lower mold 10 slide in cooperation, and the upper end surface of the ejector rod 12 and the upper end surface of the ejector block 11 are coplanar with the cavity wall of the lower mold 10, which can ensure that the raw material can be normally formed when injected between the upper mold 8 and the lower mold 10. A servo push cylinder No. 9 is fixedly installed on the upper edge of the side of the base 1, and the upper mold 8 is fixedly installed on the output end of the servo push cylinder No. 9.

[0026] During casting, the molten raw material is injected between the upper mold 8 and the lower mold 10. After it is cooled and formed, the No. 1 servo push cylinder 9 works to drive the upper mold 8 to move up to open the mold, and then the No. 2 servo push cylinder 14 works to drive the push rod 12 and the push block 11 on the bearing seat 13 to move up to eject the workpiece 43 from the lower mold 10. Then the servo motor 5 works to drive the threaded rod 2 to rotate, so that the table 4 threadedly connected to the threaded rod 2 can move, and then drive the concave frame 30 to move, so that the concave frame 30 can push the clamping jaws 36 to push the clamping jaws 36 to the upper and lower parts of the workpiece 43. At this time, the square frame 7 just abuts against the top seat 37, so that the clamping jaws 36 remain stationary, and then the table 4 continues to drive the concave frame 30 to move. At this time, the push wheel 38 rolls against the end of the concave frame 30, so that the upper and lower clamping jaws 36 are gathered together under the action of the inclined surface of the concave frame 30 to The workpiece 43 is clamped and fixed in the clamping jaws 36, and the buffer spring 32 will shrink and deform during the continued movement of the concave frame 30 to offset the thrust generated by the continued movement of the concave frame 30. When the workpiece 43 is fixed, the top plate 29 on the concave frame 30 just contacts the guide wheel 21, and then the table 4 continues to drive the concave frame 30 to move. At this time, the push wheel 38 rolls in contact with the horizontal section of the inner wall of the concave frame 30 to prevent the clamping jaws 36 from continuing to gather, so that the guide wheel 21 can roll along the inclined surface of the top plate 29, thereby driving the cutting seat 17 and the arc cutter 23 to move backward, so that the cutting seat 17 and the arc cutter 23 can fit on the workpiece 43. At this time, the gate of the workpiece 43 enters between the arc pressure ring 24 and the arc groove 41, and then the hydraulic cylinder 19 works to drive the arc cutter 23 to move downward to cut off the gate, that is, to remove the gate of the workpiece 43.
