A multi-working position production line comprises 3 sets of gravity die casting machines,robot or pouring manipulator, control system, hydraulic system, mould cooling system and vacuum system. Die casting machine is located evenly around a round rotary disk and rotates with the disk. The automatic pouring manipulator is to pour aluminum liquid in turn to the die casting machine. The working cycle of pouring, pressurizing, die-cooling, solidification, mould opening in the production line finishes automatically  
A continuous production mode can be realized; the casting part is precisely while cast production is increased obviously, on the contrary, the labor cost is lower, area taken is smaller,environment is clearly!
