When the fixed mold 11 contacts the movable mold 12, concrete is poured between the fixed mold 11 and the movable mold 12. When pouring the concrete, the vibration motors 13 are started to generate vibration. At this time, the vibration can be conducted to the movable mold 12. At this time, the movable mold 12 can drive the concrete inside it to vibrate, so that the concrete is filled more tightly between the fixed mold 11 and the movable mold 12. When the concrete solidifies, the staircase is formed. The hydraulic cylinder 14 is started to drive the movable mold 12 away from the fixed mold 11, and the formed staircase is taken out. Through the above structure, by setting the movable mold 12 to be connected with the vibration motors 13, vibration can be conducted to the concrete between the fixed mold 11 and the movable mold 12 during concrete pouring, so as to reduce the gaps between the stone materials in the concrete and reduce the air bubbles in the concrete at the same time, so as to improve the compactness of the concrete and the forming effect of the staircase.
[0026] As Figure 1 shown in Figure 4 the figure, a linear motor 2 is fixedly connected to the side wall of the movable mold 12; a first fixing plate 21 is fixedly connected to the output end of the linear motor 2; a liquid storage tank 22 is fixedly connected to the top of the first fixing plate 21; a first water pump 23 is fixedly connected to the top of the linear motor 2; the liquid storage tank 22 is connected to the first water pump 23 through a pipeline; the output end of the first water pump 23 is communicated with a liquid outlet pipe 24; during operation, before pouring concrete, the linear motor 2 is started to drive the first fixing plate 21 to move horizontally, and at the same time, the first water pump 23 is started to pump out the mold release agent in the liquid storage tank 22, and then sent into the liquid outlet pipe 24 and sprayed onto the surfaces of the fixed mold 11 and the movable mold 12. At this time, under the movement of the linear motor 2, the liquid outlet pipe 24 can spray evenly between the fixed mold 11 and the movable mold 12. Through the above structure, by setting the first water pump 23 to be connected with the liquid storage tank 22 and the liquid outlet pipe 24 and cooperating with the linear motor 2, it is convenient to spray the mold release agent on the surfaces of the fixed mold 11 and the movable mold 12, so as to facilitate the demolding of the staircase from the fixed mold 11 and the movable mold 12 after the staircase is formed, so as to improve the stability during staircase production.
[0027] As Figure 1 shown in Figure 3As shown, a second fixed plate 3 is fixedly connected to the top of the base 1; a second water pump 31 is fixedly connected to the top of the second fixed plate 3; a water inlet pipe 34 is connected to the input end of the second water pump 31; a water outlet pipe 32 is connected to the output end of the second water pump 31; a plurality of nozzles 33 are connected to the middle of the water outlet pipe 32; during operation, after the formed staircase is removed, an external water source is connected to the water inlet pipe 34, and then the second water pump 31 is started to send water flow into the water outlet pipe 32, and then it is split into a plurality of nozzles 33 and sprayed onto the fixed mold 11 and the movable mold 12 to wash the surfaces of the fixed mold 11 and the movable mold 12 and wash away the residual concrete particles. Through the above structure, by setting the second water pump 31 to connect the water outlet pipe 32 and the nozzles 33, the fixed mold 11 and the movable mold 12 can be washed to reduce the situation where concrete remains on the surfaces of the fixed mold 11 and the movable mold 12, resulting in depressions on the surface of the staircase during subsequent pouring, so as to improve the quality of the finished product.
[0028] As Figure 2 shown, two pairs of guiding holes 4 are provided on the side wall of the movable mold 12; two pairs of limiting rods 41 are fixedly connected to the side wall of the fixed mold 11; the guiding holes 4 and the limiting rods 41 are arranged in correspondence; during operation, when the hydraulic cylinder 14 drives the movable mold 12 to contact the fixed mold 11, the limiting rods 41 on the fixed mold 11 will align with the guiding holes 4 on the movable mold 12. When the movable mold 12 moves to contact the fixed mold 11, the limiting rods 41 will be inserted into the guiding holes 4. Through the above structure, by setting the guiding holes 4 and the limiting rods 41, the movement of the movable mold 12 can be limited during movement, so that the positions of the movable mold 12 and the fixed mold 11 are aligned, so as to reduce the situation where the movable mold 12 is skewed when contacting the fixed mold 11, resulting in affecting the levelness of the staircase.
[0029] As Figure 2 shown, a plurality of screw rods 5 are rotatably fitted in the middle of the base 1; a backing plate 51 is fixedly connected to the bottom of the screw rod 5; during operation, when the base 1 is placed on the ground of the working area, at this time the backing plate 51 will contact the ground.

Through the above structure, by setting the screw rods 5 and the backing plate 51, the levelness of the base 1 can be easily adjusted to reduce the situation where the position of the base 1 is inclined, resulting in affecting the production effect of the staircase.
[0030] As Figure 2 and Figure 5As shown, a pair of damping springs 6 are fixedly connected to the inner side wall of the sliding groove 17; a baffle 61 is fixedly connected to the end of the damping spring 6; during operation, when the hydraulic cylinder 14 drives the moving die 12 away from the fixed die 11, the slider 16 will be driven to slide in the sliding groove 17. When the slider 16 slides close to the end of the sliding groove 17, it will contact the baffle 61. At this time, the damping spring 6 can be contracted, which can reduce the impact force between the slider 16 and the baffle 61. Through the above structure, the damping spring 6 and the baffle 61 are provided to reduce the impact force generated between the slider 16 and the inner wall of the sliding groove 17 during movement, so as to improve the stability during use and increase the overall service life.
[0031] As Figure 1 shown, a level 7 is fixedly connected to the side wall of the base 1; the level 7 is arranged horizontally; during operation, when adjusting the levelness of the base 1, the horizontal state of the level 7 can be observed to judge whether the position of the base 1 is horizontal. Through the above structure, the level 7 is provided to facilitate the observation of the levelness of the base 1, so as to improve the convenience during use and reduce the situation that the base 1 is inclined and difficult to detect.
[0032] Working principle: When manufacturing precast concrete stairs, start the hydraulic cylinder 14 to push the movable mold 12 towards the fixed mold 11. When the fixed mold 11 contacts the movable mold 12, pour the concrete between the fixed mold 11 and the movable mold 12. Start the vibration motor 13 to generate vibration during the concrete pouring. At this time, the vibration can be transmitted to the movable mold 12, and the movable mold 12 can drive the concrete inside it to vibrate, making the concrete fill more tightly between the fixed mold 11 and the movable mold 12. When the concrete solidifies, the stairs are formed. Start the hydraulic cylinder 14 to drive the movable mold 12 away from the fixed mold 11, take out the formed stairs. Before pouring concrete again, start the linear motor 2 to drive the first fixing plate 21 to move horizontally. At the same time, start the first water pump 23 to pump out the release agent in the liquid storage tank 22, then send it into the liquid outlet pipe 24, and then spray it onto the surfaces of the fixed mold 11 and the movable mold 12. At this time, under the movement of the linear motor 2, the liquid outlet pipe 24 can spray evenly between the fixed mold 11 and the movable mold 12. When the formed stairs are removed, connect the external water source to the water inlet pipe 34, then start the second water pump 31 to send the water flow into the water outlet pipe 32, and then divert it to multiple nozzles 33, and then spray it onto the fixed mold 11 and the movable mold 12 to wash the surfaces of the fixed mold 11 and the movable mold 12 and wash away the remaining concrete particles. When the hydraulic cylinder 14 drives the movable mold 12 to contact the fixed mold 11, the limit rod 41 on the fixed mold 11 will align with the guiding hole 4 on the movable mold 12. When the movable mold 12 moves to contact the fixed mold 11, the limit rod 41 will be inserted into the guiding hole 4. When the base 1 is placed on the ground of the working area, at this time, the cushion plate 51 will contact the ground. When the ground is uneven, the screw rods 5 can be rotated respectively to change the height of the base 1 and keep the base 1 in a horizontal state. When the hydraulic cylinder 14 drives the movable mold 12 away from the fixed mold 11, it will drive the slider 16 to slide in the chute 17. When the slider 16 slides close to the end of the chute 17, it will contact the baffle 61. At this time, the damping spring 6 can be contracted to reduce the impact force between the slider 16 and the baffle 61. When adjusting the levelness of the base 1, the horizontal state of the spirit level 7 can be observed to judge whether the position of the base 1 is horizontal.
