10. A casting process of an aluminum alloy casting apparatus for improving production efficiency according to claim 9, comprising the steps of:
s1, driving the first driving device to send the aluminum alloy liquid in the holding furnace (2) into the pouring ladle (6) through the liquid outlet pipe (7);
s2, driving the rotating shaft (17) to drive the supporting plate (12) and the cross (8) to rotate through the first driving mechanism, and rotating and positioning the pouring ladle (6) above the casting sand box (25);
s3, driving the cross (8) to drive the pouring ladle (6) to move downwards in the vertical direction through a third driving device (9), so that the first pouring gate (4) is communicated with the second pouring gate (26);
s4, opening the first pouring gate (4) by controlling the electric valve (5), enabling the aluminum alloy liquid to enter the casting sand box (25), and closing the electric valve (5) after the aluminum alloy liquid is completely poured;
s5, driving the cross (8) to drive the pouring ladle (6) to move upwards in the vertical direction through the third driving device (9), so that the first pouring gate (4) is far away from the second pouring gate (26);
s6, cooling and forming the aluminum alloy liquid in the casting sand box (25) to obtain a corresponding aluminum alloy casting;
and S7, driving the casting sand box (25) to enter and exit the box body (1) through the through groove (29) by the second driving mechanism, and taking out the formed aluminum alloy casting from the casting sand box (25).
