Pouring casting liquid into the molding cavity through the liquid guide pipe, and driving the rotating rod 72 to repeatedly rotate forward and backward through the rotating motor 723, so that the lifting slide block 73 is utilized to drive the lower die 80 and the upper die 60 to rotate together around the central line of the lower die 60 (in the rotating process of the upper die 60 and the lower die 80, the balls 600 rotate in the arc-shaped track of the arc-shaped top block 930, and the clamping blocks 93 are mutually limited and do not rotate); in the process of rotating the lower die 80 around the central line of the lower die 80, the arc-shaped clamping blocks 83 are arranged on the annular guide ring 71 and rotate around the central line of the annular guide ring 71 (namely, the central line of the lower die 80), and due to the wavy structure of the end face of the annular guide ring 71 and the elastic action of the reset spring 74, the lower die 80 and the upper die 60 reciprocate up and down in synchronization in the rotating process, so that molten metal in a molding die cavity is uniformly filled, and defects of molded parts are avoided.

Step four, after casting, the driving shaft 941 is started to reversely rotate, so that the clamping block 93 moves in a direction away from the lower die 80, and the limitation of the clamping block 93 on the upper die 60 and the lower die 80 is released; then, the lifting mechanism 50 is started to reset the upper die 60, and the parts are left in the forming grooves of the lower die 80; and then, taking out the part from the forming groove and carrying out the next part casting.
