Description

Technical Field

[0001] The utility model belongs to the field of molds, and in particular relates to an assembled staircase mold with a vibration exhaust mechanism. Background Art

[0002] By using prefabricated staircase molds, the entire staircase is prefabricated in the factory and can be assembled on-site or in the factory, allowing for quick installation on-site. For example, the utility model patent with authorization announcement number CN218748434U proposes an assembled prefabricated staircase mold, which includes a mold body, a base disposed at the bottom end of the mold body, and a limited rotation groove. The mold body is composed of a first module, a second module, a third module, and symmetrically arranged mounting plates. The first and third modules are respectively disposed at both ends of the second module, and the symmetrically arranged mounting plates are respectively disposed at the ends of the first module.

[0003] However, the existing mold is relatively static, and the air in the slurry cannot be discharged in time, resulting in honeycomb holes inside the formed stairs, which affects the quality. In addition, after the stairs are formed, they stick to the mold and are difficult to release from the mold. Therefore, it is necessary to improve it. Summary of the Invention

[0004] The purpose of the utility model is to provide an assembled staircase mold with a vibrating exhaust mechanism, which solves the problem that the existing mold is relatively static and the air in the slurry cannot be discharged in time, resulting in honeycomb holes inside the molded stairs, affecting the quality. Moreover, after the stairs are formed, they are adhered to the mold and are difficult to demold from the mold.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an assembled staircase mold with a vibration exhaust mechanism, including a base plate, the upper end of the base plate is fixedly connected to a sleeve, the inner side of the sleeve is slidably connected to a sliding column, the top of the sliding column is fixedly connected to the mold, the inner side of the mold is fixedly connected to the mold base, the bottom of the seal is fixedly connected to a bevel ring, an electric motor is fixedly installed in the middle of the upper end of the base plate, the end of the output shaft of the motor is fixedly connected to an L-shaped rod, and the L-shaped rod is in conflict with the bevel ring.

[0006] The principle of the utility model is as follows: when in use, the slurry is first put into the mold, and then the motor is started, which drives the L-shaped rod to rotate. The L-shaped rod makes a circular motion on the bevel ring, and the characteristics of the bevel ring and the elastic force of the spring are used to reset, so that the mold can vibrate up and down repeatedly, thereby expelling the air in the slurry and preventing the formation of honeycomb holes in the formed stairs, thereby improving the quality of the stairs. Moreover, when the mold falls, it hits the travel block, which can further shake out the air in the slurry.

[0007] After the stairs are formed in the mold, the pipe sleeve is rotated by the pull rod, and the pipe sleeve drives the adjusting rod to rotate. The linkage plate on the adjusting rod moves in its axial direction, and then the linkage plate drives the sliding rod to move upward, and the top block on the top of the sliding rod assists in lifting the stairs to facilitate its demoulding.

[0008] The beneficial effect of the utility model is that an elastic support assembly consisting of a sleeve, a sliding column and a spring is arranged below the mold, the elastic support assembly is used to support the mold, and then a combination of an electric motor, an L-shaped rod and a bevel ring is arranged below the mold. In this way, the mold can vibrate up and down cyclically, and the air in the slurry can be discharged, thereby preventing the formation of honeycomb holes in the stairs after molding, thereby improving the quality of the stairs.

[0009] By setting a combination of relative threaded cooperation between an adjusting rod and a linkage plate at the bottom of the mold, and setting a sliding rod with a top block on the linkage plate, the top block is located at the mold base. In this way, after the stairs are formed, the top block can be lifted out of the mold by utilizing its liftability, thereby facilitating demoulding.

[0010] Furthermore, a spring is provided inside the sleeve, one end of the spring being fixedly connected to the sliding post, and the other end of the spring being fixedly connected to the inner surface of the sleeve. The provision of the spring can assist in resetting the mold.

[0011] Furthermore, a travel block is fixedly connected to the upper end of the base plate, and the travel block contacts the mold. Through the arrangement of the travel block, when the mold is reset downward, it collides with the mold, and the air in the slurry can be shaken out in one step.

[0012] Furthermore, a slide rod is slidably connected to the lower end of the mold, one end of which is fixedly connected to a top block, which is slidably connected to the mold base. The bottom of the slide rod is fixedly connected to a linkage plate, and an adjustment rod is threadedly connected to the interior of the linkage plate. The relative threaded movement between the adjustment rod and the linkage plate can cause the slide rod to produce vertical displacement.

[0013] Furthermore, a limiting ring is fixedly connected to the middle section of the rod body of the limiting rod, and the limiting ring contacts the inner surface of the mold. The setting of the limiting ring has a positioning effect on the sliding rod and the top block.

[0014] Furthermore, a shaft tail fixing seat is installed on the top of the adjusting rod via a bearing, and the shaft tail fixing seat is fixedly connected to the bottom of the mold. The arrangement of the shaft tail fixing seat facilitates the installation of the adjusting rod.

[0015] Furthermore, the bottom of the adjusting rod is fixedly connected to a pipe sleeve, the interior of the pipe sleeve is slidably connected to a pull rod, and both ends of the pull rod are fixedly connected to limit balls. The arrangement of the pull rod facilitates the rotation of the adjusting rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is further described in detail through specific implementation methods:

[0021] The figure marks in the drawings of the specification include: base plate 1, sleeve 2, sliding column 3, spring 4, mold 5, mold base 6, bevel ring 7, motor 8, L-shaped rod 9, stroke block 10, sliding rod 11, top block 12, linkage plate 13, limit ring 14, shaft tail fixing seat 15, adjusting rod 16, pipe sleeve 17, pull rod 18, and limit ball 19.

[0022] like Figure 1 、 Figure 2 、 Figure 4 As shown, this embodiment provides an assembled staircase mold with a vibration exhaust mechanism, comprising a base plate 1. A sleeve 2 is fixedly connected to the upper end of the base plate 1. A sliding post 3 is slidably connected to the inner side of the sleeve 2. A spring 4 is disposed on the inner side of the sleeve 2, one end of the spring 4 being fixedly connected to the sliding post 3 and the other end being fixedly connected to the inner surface of the sleeve 2. The provision of spring 4 assists in resetting the mold 5. The top of the sliding post 3 is fixedly connected to the mold 5, and the inner side of the mold 5 is fixedly connected to the mold base 6. A bevel ring 7 is fixedly connected to the bottom of the seal 5. A motor 8 is fixedly mounted in the middle of the upper end of the base plate 1. The end of the output shaft of the motor 8 is fixedly connected to an L-shaped rod 9, which abuts against the bevel ring 7. A travel block 10 is fixedly connected to the upper end of the base plate 1 and contacts the mold 5. The travel block 10 allows the mold 5 to collide with the travel block when it returns downward, thereby vibrating out the air within the slurry.

[0023] like Figure 2 、 Figure 3As shown, a slide rod 11 is slidably connected to the lower end of the mold 5. One end of the slide rod 11 is fixedly connected to a top block 12, which is slidably connected to the mold base 6. The bottom of the slide rod 11 is fixedly connected to a linkage plate 13, and the interior of the linkage plate 13 is threadedly connected to an adjustment rod 16. The relative threaded movement between the adjustment rod 16 and the linkage plate 13 can cause the slide rod 11 to produce vertical displacement.

[0024] like Figure 2 、 Figure 3 As shown, the middle section of the rod body of the limiting rod 11 is fixedly connected to a limiting ring 14, and the limiting ring 14 contacts the inner surface of the mold 5. The setting of the limiting ring 14 has a positioning effect on the sliding rod 11 and the top block 12. The top of the adjusting rod 16 is installed with a shaft tail fixing seat 15 through a bearing, and the shaft tail fixing seat 15 is fixedly connected to the bottom of the mold 5. The setting of the shaft tail fixing seat 15 facilitates the installation of the adjusting rod 16. The bottom of the adjusting rod 16 is fixedly connected to a pipe sleeve 17, and the inside of the pipe sleeve 17 is slidably connected to a pull rod 18, and both ends of the pull rod 18 are fixedly connected to a limiting ball 19. The setting of the pull rod 18 facilitates the rotation of the adjusting rod 16.

[0025] The specific implementation process of the utility model is as follows: when in use, the slurry is first put into the mold 5, and then the motor 8 is started. The motor 8 will drive the L-shaped rod 9 to rotate. The L-shaped rod 9 makes a circular motion on the bevel ring 7. The characteristics of the bevel ring 7 and the elastic force of the spring 4 are used to reset, so that the mold 5 can be repeatedly vibrated up and down, thereby expelling the air in the slurry and preventing the formation of honeycomb holes in the formed stairs, thereby improving the quality of the stairs. Moreover, when the mold 5 falls, it will hit the travel block 10, which can be used to shake out the air in the slurry in one step.

[0026] After the stairs are formed in the mold 5, the sleeve 17 is rotated by the pull rod 18, and the sleeve 17 drives the adjusting rod 16 to rotate. The linkage plate 13 on the adjusting rod 16 moves in its axial direction, and then the linkage plate 13 drives the slide rod 11 to move upward, and the top block 12 on the top of the slide rod 11 assists in lifting the stairs to facilitate its demoulding.

[0027] This solution arranges an elastic support assembly consisting of a sleeve 2, a slide column 3 and a spring 4 below the mold 5, uses the elastic support assembly to support the mold 5, and then arranges a combination of a motor 8, an L-shaped rod 9 and a bevel ring 7 below the mold 5. This allows the mold 5 to vibrate up and down periodically, which can discharge the air in the slurry and prevent the formation of honeycomb holes in the stairs after molding, thereby improving the quality of the stairs.

[0028] By setting a combination of relative threaded engagement between an adjusting rod 16 and a linkage plate 13 at the bottom of the mold, and setting a sliding rod 11 with a top block 12 on the linkage plate 13, and the top block 12 is located at the mold base 6, after the stairs are formed, the top block 12 can be assisted to be ejected from the mold 5 by utilizing its liftability, thereby achieving the purpose of facilitating demoulding.
