When taking out the workpiece, first drive the slider 5 to slide to one end in the installation groove 4, so as to drive the rotating rod 10 and the extension mechanism 9 to move toward one end of the rotating rod 10. After the die-cast workpiece is taken out by a group of manipulator bodies 7, it is moved to the original position, and the two groups of manipulator bodies 7 are retracted by the extension mechanism 9 at the same time to reduce the space occupied during rotation, and then the rotating mechanism 8 is started to drive the rotating rod 10 to rotate, and the positions of the two groups of manipulator bodies 7 are interchanged, and then the manipulator body 7 with the workpiece is clamped to place the workpiece, and the manipulator body 7 located at the die-casting machine continues to clamp the workpiece and work in sequence, thereby improving the speed of the manipulator in the process of taking the workpiece and placing it. When it comes to small workpieces that are quickly die-cast, it can keep up with the working rhythm of the die-casting machine, which is convenient for improving work production efficiency.

[0022] Furthermore, the rotating mechanism 8 includes a rotating column 801, which is rotatably mounted on the upper surface of the mounting plate 6.
