9. A robotic casting method, the method comprising:
the method comprises the following steps: the two die closing oil cylinders (6) push the two fixed die plates (7) to move until a left elastic die (8) and a right elastic die (9) on the two fixed die plates (7) are tightly attached to each other, and at the moment, first springs (816) in the left elastic die (8) and the right elastic die (9) are not in a fully compressed state;
step two: pouring 740-780 ℃ of aluminum liquid into the cavity (824) through the casting holes (825) in the left elastic die (8) and the right elastic die (9) by the casting equipment, and stopping casting when the high-temperature aluminum liquid in the cavity (824) is about to reach the orifice plane of the casting holes (825) by 10-15 mm;
step three: the second hydraulic cylinder (11) pushes the turnover plate (12) to enable the sealing plug body (14) at one end of the connecting rod (13) to be embedded into the casting hole (825) and seal the high-temperature aluminum liquid. The two die closing oil cylinders (6) push the two fixed die plates (7) again to enable the first springs (816) in the left elastic die (8) and the right elastic die (9) to be completely in a compressed state, and the die base (81) and the die sleeve (82) are tightly attached to each other, so that the aluminum liquid in the die cavity (824) is more compact under the action of pressure;
step four: the two first hydraulic cylinders (4) sequentially push the two rotating seats (3) to rotate, so that the rotating seats (3) sequentially and repeatedly rotate in the left and right directions, and the aluminum liquid in the cavity (824) is completely filled in the cavity (824) until the aluminum liquid is cooled and solidified;
step five: the die closing oil cylinder (6) drives the two fixed die plates (7) to move, and a casting is taken out.
10. A robotic casting method as claimed in claim 9, wherein in said first step the spacing between the mould base (81) and the adjacent side of the mould sleeve (82) is not less than 5 mm.
