Description

Technical Field

[0001] This utility model relates to the field of prefabricated staircase technology, and in particular to a prefabricated staircase forming mold ejection mechanism. Background Technology

[0002] Precast concrete refers to concrete products manufactured in factories using standardized and mechanized methods. In contrast, traditional cast-in-place concrete requires on-site formwork, pouring, and curing. Staircases are also used in buildings for vertical transportation between floors, facilitating connections between floors and addressing significant height differences. Even in multi-story and high-rise buildings where elevators and escalators are the primary means of vertical transportation, staircases are still necessary.

[0003] Precast stairs require the addition of a steel reinforcement frame to the mold and the pouring of concrete during manufacturing. After the concrete dries, demolding is necessary, which is inconvenient due to the weight of the concrete. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems and deficiencies by proposing a prefabricated staircase forming mold ejection mechanism: The hydraulic push rod in the mounting base is activated, extending into the ejection hole and contacting the contact protrusion. The ejection plate on the contact protrusion ejects the staircase from the mold body, completing the demolding process and facilitating demolding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example:

[0020] Reference Figure 1-3 As shown, a prefabricated stair forming mold ejection mechanism includes a support structure 1 and a mold body 2 placed on the outer wall of the top of the support structure 1. The bottom inner wall of the mold body 2 is provided with auxiliary components 3 distributed at equal intervals.

[0021] The auxiliary component 3 includes sliding blocks 4 welded at equal intervals to the bottom outer wall of the mold body 2, sliding grooves 5 opened on the bottom inner wall of the mold body 2 at the center of the sliding blocks 4, and ejection holes 6 opened at the center of the sliding blocks 4.

[0022] The mold body 2 is slidably connected to the inner wall of the sliding groove 5 with an ejector plate 7. The bottom outer wall of the ejector plate 7 is welded with a contact protrusion 9 at the ejection hole 6. The ejector plate 7 is restricted to the inside of the mold body 2 by the contact protrusion 9 and the sliding groove 5. The anti-stick texture 8 on the ejector plate 7, together with the reagent, facilitates detachment from the concrete stairs.

[0023] The outer wall of the contact protrusion 9 is slidably connected to the inner wall of the ejection hole 6, and the top outer wall of the ejection plate 7 is provided with equally spaced anti-stick textures 8.

[0024] The support structure 1 includes a support base 10, a limiting groove 11 equally spaced on the top outer wall of the support base 10, a mounting base 12 installed at the center of the top outer wall of the support base 10, and a hydraulic push rod 13 installed on the inner wall of the mounting base 12. The hydraulic push rod 13 extends into the ejection hole 6 and contacts the contact protrusion 9. The ejection plate 7 on the contact protrusion 9 pushes the stairs out of the mold body 2, completing the demolding and facilitating demolding.

[0025] The top outer wall of the hydraulic push rod 13 contacts the bottom outer wall of the contact protrusion 9. The top outer wall of the hydraulic push rod 13 is slidably connected to the ejection hole 6. The hydraulic push rod 13 exerts upward force on the ejection plate 7 through the ejection hole 6, pushing the staircase out of the mold body 2 for easy demolding.

[0026] Ventilation holes 15 are provided at equal intervals on both outer walls of the support base 10. The bottom outer wall of the mold body 2 is placed in the limiting groove 11 at the top of the support base 10. A vibration motor 14 is installed on the outer wall of the sliding block 4. The ventilation holes 15 on the support base 10 facilitate airflow and help dry the concrete inside the mold body 2. After the vibration motor 14 is started, it drives the mold body 2 to vibrate. After the mold body 2 vibrates, the concrete is compacted in the mold body 2.

[0027] The vibration motor 14 and the hydraulic push rod 13 are connected to a switch via wires, and the switch is connected to a power source via wires.

[0028] Working principle: When in use, the mold body 2 is placed in the limiting groove 11 on the support base 10. First, the inner wall of the mold body 2 is coated with a reagent to facilitate demolding. Then, the steel reinforcement skeleton is placed in the mold body 2, and concrete is poured into the inside of the mold body 2. The vibration motor 14 on the outer wall of the sliding block 4 is started. After the vibration motor 14 is started, it drives the mold body 2 to vibrate. After the mold body 2 vibrates, the concrete is compacted in the mold body 2. The vent hole 15 on the support base 10 facilitates airflow and helps dry the concrete inside the mold body 2. After the concrete dries, the hydraulic push rod 13 in the mounting base 10 is started. The hydraulic push rod 13 extends into the ejection hole 6 and contacts the contact protrusion 9. The ejection plate 7 on the contact protrusion 9 pushes the stairs out of the mold body 2, completing the demolding and facilitating demolding.
