[0002] In the manufacturing process of some products, it is often necessary to use a die-casting machine to die-cast various die-casting parts, such as automobile and motorcycle accessories, daily hardware, and household appliance accessories. The die-casting machine is usually equipped with a mold, and the molten metal is hydraulically injected into the mold by a pressure injection device.

With the development of industry, the application of pick-up machines replacing manual pick-up in the manufacturing industry is increasing. For example, a dual-servo pick-up machine disclosed in the Chinese utility model patent (publication number: CN214643645U) includes a frame, a first motor, a first lever, a second lever, a third lever and a manipulator. The first motor is arranged on the frame, one end of the first lever is fixedly mounted on the output shaft of the first motor, one end of the second lever is rotatably arranged on the frame, the free end of the first lever is hinged to one end of the third lever, and the free end of the second lever is hinged to the other end of the third lever; the pick-up machine also includes a telescopic rod and a rotating cylinder; one end of the telescopic rod is rotatably mounted on the third lever, and the other end of the telescopic rod is fixedly connected to the manipulator; the rotating cylinder is arranged on the third lever, and the output end of the rotating cylinder is transmission-connected to the telescopic rod; the pick-up machine also includes a lifting mechanism and a transverse movement device.
