[0045] When the centrifuge for roll casting is in normal use, start the first cylinder 311. The first cylinder 311 pushes the connecting block 313 to the right. The connecting block 313 moves to the right and pushes the sliding seat 321. The sliding seat 321 drives the slider 324 to slide along the sliding groove 325, causing the second cylinder 322 to move to the specified position to the right. Start the second cylinder 322. The second cylinder 322 pushes the limiting rod 323 downward so that the limiting rod 323 contacts the groove opened at the upper end of the top mold 223. When starting the motor 211 to drive the top mold 223 to rotate, the limiting rod 323 slides along the groove opened at the upper end of the top mold 223, making the rotation of the mold stable and not prone to deflection. When the casting is completed, start the first cylinder 311 and the second cylinder 322 to move the limiting rod 323 upward and move the sliding seat 321 to the left, so that when removing the bottom mold 221, the middle mold 222, and the top mold 223, the sliding seat 321 will not cause obstruction, facilitating the operation of the worker.
