The front and rear molds are then closed. The fixing folding plate in the mold-closing reinforcement is wrapped around the perimeter of the front mold and secured with nuts through the fixing holes on the connecting screws. This completes the mold-closing process. Then, the rotating abutment plate is rotated, and the telescopic rod is stretched, causing the rotating abutment plate to abut against the rear mold, improving the stability of the mold-closing. Concrete is poured into the pouring hole to form a precast staircase. Because the staircase mold cavity is vertically set, the staircase components can be formed in one step, reducing the difficulty of finishing the surface and greatly improving the quality of the staircase components. At the same time, this structure uses the mold-closing fixing component and the rotating support component to cooperate to close the front and rear molds. After molding, the rotating abutment plate can be removed from the rear mold by removing the nuts and adjusting the length of the telescopic rod, thus completing the demolding. The demolding is simple, easy to operate, and highly practical.
