[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0021] Embodiment 1: As Figures 1 - 4 shown, the present utility model provides a technical solution: a precast staircase mold facilitating demolding, including a base frame 1, a stepped tooth mold 2 and a baffle side mold 3. Driving components are symmetrically arranged on both sides of the base frame 1. The top of the driving component is connected with a supporting bottom frame 8. A guiding block 9 is fixedly installed on the top of the supporting bottom frame 8. A sliding frame 10 is slidably installed on the top of the supporting bottom frame 8. One end of the top of the sliding frame 10 is provided with a handle 13.

[0022] In this embodiment, the driving mechanism drives the supporting bottom frame 8 and the sliding frame 10 to carry the formed precast staircase out of the work position. Then, by grasping and pushing the handle 13, the sliding frame 10 slides along the guiding block 9 to move the formed precast staircase onto the external conveying device, thereby realizing rapid demolding of the formed precast staircase, reducing the demolding difficulty, saving labor and time costs, improving work efficiency, meeting the actual use requirements. An external conveying device for transporting the formed precast staircase is arranged on one side of the base frame 1, and its height is the same as that of the supporting bottom frame 8, which can enable the sliding frame 10 to smoothly slide the formed precast staircase onto its top.

[0023] Embodiment 2: As Figures 1 - 4As shown in the figure, one end of the top of the base frame 1 is provided with a fixing plate 14. On one side of the fixing plate 14, there are two cylinders 15. The output end of the cylinder 15 movably penetrates through the fixing plate 14 and is connected to the baffle side die 3. At the bottom of one side of the baffle side die 3, there are two guide wheels 16. The guide wheels 16 are slidably connected to the base frame 1. The driving assembly includes two brackets 4. On one side of a single bracket 4, there is a motor 5. The output end of the motor 5 movably penetrates through the single bracket 4 and is connected to a lead screw 6. On the outer side of the lead screw 6, there are two sliders 7. The top of the slider 7 is fixedly connected to the supporting bottom frame 8. One end of the top of the base frame 1 is provided with a plurality of support frames 17. One end of the support frame 17 is fixedly connected to a fixing frame 18. The fixing frame 18 is fixedly installed on one side of the stepped tooth die 2. Both ends of the top of the sliding frame 10 are provided with positioning grooves 11. Inside the positioning grooves 11, there are positioning pins 12 inserted. The bottom of the positioning pin 12 penetrates through the guide block 9 and the supporting bottom frame 8. There is a cavity between the base frame 1 and the baffle side die 3. The supporting bottom frame 8 and the sliding frame 10 are closely arranged inside the cavity.

[0024] In this embodiment, by the telescopic movement of the cylinder 15, the baffle side die 3 is driven to be combined with or separated from the stepped tooth die 2. At the same time, the guide wheels 16 roll on the base frame 1, which can maintain the stability of the movement of the baffle side die 3, thereby reducing the difficulty of combining or separating the molds, saving labor costs, improving work efficiency, and avoiding potential safety hazards. By driving the lead screw 6 to rotate through the motor 5, the two sliders 7 are urged to slide left and right on the lead screw 6, thereby driving the supporting bottom frame 8 to move into or out of the working station. The support frame 17 can support the fixing frame 18 to maintain its stability. At the same time, the stepped tooth die 2 is arranged above the base frame 1 by using the fixing frame 18, leaving a cavity for use as the bearing working station of the sliding frame 10. By inserting the positioning pin 12 into the inside of the positioning groove 11, the sliding frame 10 is fixed, preventing the sliding frame 10 from sliding and misaligning when bearing the precast staircase, thereby improving its stability and reducing the actual use difficulty.

[0025] The working principle of this embodiment: When in use, first start the two guide blocks 9 simultaneously, drive the corresponding lead screws 6 to rotate, and move the supporting bottom frame 8 and the sliding frame 10 into the cavity. Then, start the two cylinders 15, push the baffle side die 3 to slide on the base frame 1 to combine it with the stepped tooth die 2. After the mold is closed, pour concrete into the mold cavity and wait for the precast staircase to be formed. Then, when the precast staircase is formed, start the two cylinders 15 again to pull the baffle side die 3 away from the stepped tooth die 2. Then, use the motor 5 to drive the lead screw 6 to rotate, and move the sliding frame 10 bearing the precast staircase out of the cavity. Finally, take out the two positioning pins 12, grasp and push the handle 13, and make the sliding frame 10 slide along the guide block 9 to move the precast staircase onto the external conveying equipment, thereby completing the use of the precast staircase mold that is convenient for demolding.

[0026] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
