Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides Figure 1-6 The mold for a prefabricated staircase that is easy to demould comprises a base plate 1, a fixed template 2 is provided on the top of the base plate 1, a movable template 3 is provided on the side of the fixed template 2 and on the top of the base plate 1, and further comprises a pressure-bearing component and a partition component 9;

[0024] It should be noted that the fixed template 2 is welded to the bottom plate 1, and a sealing strip 201 is provided on the bottom side of the fixed template 2. The sealing strip 201 is glued to the side of the fixed template 2.

[0025] Specifically, the pressure-bearing assembly includes a reinforcing plate 4 symmetrically arranged on the back of the movable template 3, and a rolling portion is provided at the bottom of the reinforcing plate 4 for reducing the friction of the movable template 3;

[0026] The rolling part includes a rolling wheel 401 arranged at the bottom of the reinforcing plate 4, and a movable groove 101 for the rolling of the rolling wheel 401 is opened on the top of the bottom plate 1.

[0027] It should be noted that the reinforcing plate 4 is welded and fixed to the movable formwork 3. The reinforcing plate 4 can roll in the movable groove 101 via the rolling wheel 401 to realize the movement of the movable formwork 3 on the top of the base plate 1. A vibration motor 8 for vibrating and compacting the concrete is provided on the side of the movable formwork 3.

[0028] The side of the reinforcing plate 4 is provided with a pushing portion for pushing the movable template 3 to move;

[0029] Specifically, the driving part includes a motor 7 disposed on the top of the base plate 1. The output end of the motor 7 is fixedly connected to a screw 701. A threaded sleeve 6 is sleeved on the outer side of the screw 701. A reinforcing rod 5 is disposed at the end of the threaded sleeve 6. The reinforcing rod 5 is disposed on the opposite side of the reinforcing plate 4.
