[0026] In this invention, during use, the arc-shaped auxiliary component 5 is first installed on the inner bottom wall of the mold 4. Then, the moving mechanism is activated, which allows the mounting brackets 9 on both sides to move relative to each other, thereby moving the mounting plate 1 as well. At this time, the second abutting components on both sides are activated, and the limiting end abuts against the inner bottom wall of the arc-shaped auxiliary component 5, thereby limiting the arc-shaped auxiliary component 5 and keeping it in a bent state. Then, the glue-impregnated fiber cloth is laid on the inner bottom wall of the arc-shaped auxiliary component 5 and located below the abutting components on both sides. The abutting components on both sides are activated, and then the limiting ends of the abutting components on both sides are activated. At this time, the fiber cloth is fixed between the limiting ends of the abutting components and the inner bottom wall of the arc-shaped auxiliary component 5. After a period of shaping, the abutting components and the second abutting components are activated, causing the limiting ends of the abutting components and the second abutting components to move upward. Finally, through the moving mechanism, the mounting brackets 9 drive the mounting plate 1 to move away from the central axis of the mold 4, thereby removing the shaped arc-shaped auxiliary component 5 from the inside of the mold 4.
