For example, the Chinese utility model patent with the announcement number CN203370998U has disclosed A fully automatic filling machine mechanical gripper used for a jewelry wax injection machine. The bottom of the mechanical gripper gripper is equipped with a vertical and horizontal movement system. The vertical and horizontal movement system is equipped with a wax injection platform.
