[0033] Working principle: During operation, the power supply slot 20 in the guide rail 22 supplies power to the device through the receiver 18. The position of the top plate 1 is adjusted by the moving rod connected to the base 10 and the base fixing block 9 and the motor connected to the moving rod, so that the top plate 1 is above the sand core. The electric push rod 2 pushes the side plate 11, and the two side plates 11 and the top plate 1 wrap around the sand core. The air pump 15 works to inflate the air bag 13 so that it inflates and fits tightly against the sand core. When the air pressure sensor in the air bag 13 detects the appropriate air pressure, it will stop the air pump 15 and cause the device to pick up the sand core. The bottom motor 17 drives the transmission gear 16 to rotate in the gear groove 19, and the device moves along the guide rail 22 by relying on the meshing fixed teeth 21.
