[0024] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.
[0025] See also Figure 1-3 The utility model provides a technical solution: a prefabricated component demoulding auxiliary device, comprising an ejection mechanism installed in a mold 1 for ejecting a concrete component from the mold 1, the concrete component formed in the mold 1 is ejected from the mold 1 from bottom to top through the ejection mechanism, the demoulding step is omitted, the integrity of the concrete component is ensured, and the mold 1 can be reused;
[0026] Specifically, the ejection mechanism includes a contact assembly for contacting the bottom of the concrete member and a lifting unit for lifting the contact assembly upward, and the contact assembly includes a bottom plate 201 that can be lifted and lowered in the mold 1 for contacting the bottom surface of the concrete member and a rod body 204 installed on the bottom surface of the bottom plate 201 for contacting the lifting unit.
[0027] The lifting unit includes a top block 202 and a driving assembly for driving the top block to move horizontally. A slope 203 is provided at the top of the top block 202 for lifting the contact assembly upward when the top block 202 moves in a set direction.
[0028] When in use, first pour concrete into the mold 1, and the concrete will be formed in the area above the bottom plate 201 in the mold 1. The formed concrete component is located above the bottom plate 201. When the concrete component is formed and needs to be separated from the mold 1, the lifting unit is brought into contact with the rod body 204, and the rod body 204 together with the bottom plate 201 are pushed upward, and an upward thrust is applied to the concrete component in the mold 1 through the bottom plate 201, so that the concrete component rises and is completely separated from the side of the mold 1. When the concrete component is completely separated from the inner cavity of the mold 1, the concrete component is manually separated from the bottom plate 201, thereby realizing demoulding of the concrete component from the mold 1. The demoulding is simpler and more convenient, and the labor intensity of the staff is greatly reduced. At the same time, the mold 1 and the concrete component will not be damaged, and the mold 1 can be reused later, while the quality and efficiency of demoulding can also be guaranteed.
[0029] The driving assembly drives the top block 202 to move toward the rod body 204. The top block 202 will first contact the rod body 204 through the inclined surface 203 on its surface. The thrust of the top block 202 on the rod body can be decomposed into a component force acting vertically upward on the rod body 204 through the inclined surface 203. The component force acting vertically upward on the rod body 204 can push the rod body 204 together with the bottom plate 201 to rise. The driving assembly continues to drive the top block 202 to keep moving in the same direction as before, and the top block 202 can lift the rod body together with the bottom plate 201 upward through the inclined surface 203.
[0030] The side of the bottom plate 201 that is in contact with the bottom surface of the concrete component matches the shape and size of the bottom surface of the concrete component.
[0031] The top surface of the bottom plate 201 can be in contact with the entire bottom surface of the concrete member, thereby increasing the contact area between the bottom plate 201 and the concrete member, and ensuring that the concrete member will not be damaged by the bottom plate 201 when the concrete member is lifted upward by the bottom plate 201 .
[0032] like Figure 2-3 As shown, a support layer 3 for supporting the bottom plate 201 from the bottom surface of the bottom plate 201 is fixedly installed in the inner cavity of the mold 1, and the rod body 204 passes through the support layer 3 from top to bottom.
[0033] In this embodiment, the base plate 201 is supported by the support layer 3. When pouring concrete into the mold 1, the weight of the concrete will be transmitted to the contact layer through the contact position between the support layer 3 and the base plate 201. The weight of the base plate 201 and the concrete is borne by the support layer 3 to ensure the stability of the base plate 201 during the pouring process. The support layer 3 can be a flat plate with holes, or a protrusion on the edge of the inner cavity of the mold 1, or a hollow support frame.
[0034] like Figure 2As shown, a roller 205 for contacting the inclined surface 203 is installed at the bottom of the rod body 204 .
[0035] In this embodiment, when the top block 202 pushes the rod body 204 upward through the inclined surface 203, the weight of the bottom plate 201, the weight of the concrete component, and the bonding force between the concrete component and the inner cavity side wall of the mold 1 will all act on the inclined surface 203 through the rod body 204. In order to reduce the wear of the inclined surface 203 and the rod body 204, a roller 205 is installed at the bottom of the rod body 204. The roller 205 contacts the inclined surface 203 to form rolling friction, thereby extending the service life of the top block 202 and the rod body.
[0036] like Figure 2 As shown, the rod body 204 is installed at the exact center of the bottom surface of the bottom plate 201 and is perpendicular to the bottom surface of the bottom plate 201 .
[0037] In this embodiment, the rod body 204 is located at the exact center of the bottom surface of the base plate 201, so that it can be ensured that the force acting on the bottom surface of the base plate 201 when the rod body 204 pushes the base plate 201 upward is at the exact center of the base plate 201, ensuring that the force point of the base plate 201 is located at the exact center. At the same time, the rod body 204 is perpendicular to the base plate 201, so that the vertical upward thrust applied to the rod body 204 by the inclined surface 203 can coincide with the axis of the rod body 204, thereby ensuring the stability of the rod body 204.
[0038] like Figure 2 As shown, a return spring 206 is fixedly mounted on the surface of the rod body 204 , and the top end of the return spring 206 is against or fixed to the bottom surface of the support layer 3 .
[0039] In this embodiment, after the demolding is completed, the top block 202 is reset, and the bottom plate 201 needs to be lowered and reset as well. The reset spring 206 will be compressed when the rod body 204 and the bottom plate 201 rise. After the top block 202 is reset, the reset spring 206 helps the bottom plate 201 to be lowered and reset through its own elastic force.
[0040] like Figure 1-2 As shown, the driving assembly includes a screw rod 207 threadedly engaged with the mold 1 and a handle 208 fixed to one end of the screw rod 207 , and one end of the screw rod 207 away from the handle 208 passes through the mold 1 and is rotatably connected to the top block 202 .
[0041] In this embodiment, the screw rod 207 is threadedly engaged with the mold 1. The screw rod 207 is driven to rotate by rotating the handle 208. The screw rod 207 will enter or exit the inner cavity of the mold 1. The end of the screw rod 207 entering the mold 1 is rotatably connected to the top block 202. The movement of the screw rod 207 can drive the top block 202 to move, thereby driving the top block 202.
[0042] like Figure 3As shown, a protrusion 401 is fixedly mounted on the top of the mold 1 , and a ring 402 is sleeved on the surface of the protrusion 401 .
[0043] In this embodiment, before pouring concrete, it is necessary to lay a film in the mold 1 to separate the mold 1 and the concrete. When installing the film, the film is pressed on the upper end of the protrusion 401, and then the ring 402 is put from the upper end of the film downward on the outside of the protrusion 401, and the film is pressed in the gap between the ring 402 and the protrusion 401 to fix the film.
[0044] like Figure 3 As shown, a slide groove 403 is provided on the top surface of the mold 1 , and a slide rod 404 fixedly connected to the top of the collar 402 is slidably installed in the slide groove 403 .
[0045] In this embodiment, the slide rod 404 is slidably installed in the slide groove 403, and then the ring 402 is fixed on the top of the slide rod 404, the ring 402 is added to increase the lifting weight, and the slide rod 404 is a quadrangular prism, and the opening shape of the slide groove 403 matches the cross-sectional shape of the slide rod 404, ensuring that the ring 402 can be quickly put on the outside of the protrusion 401.
[0046] like Figure 1-2 As shown, an oil box 501 is fixedly installed on the outer surface of the mold 1, and the bottom end of the oil box 501 is connected to a lubrication sleeve 502 through an oil pipe. The lubrication sleeve 502 is sleeved on the outer surface of the screw rod 207 for contacting with the screw rod 207 to lubricate the screw rod 207.
[0047] In this embodiment, during the long-term use of the screw rod 207, the screw rod 207 can be lubricated by the oil box 501. First, a certain amount of lubricating oil is poured into the oil box 501, and the lubricating oil will be sent to the lubricating sleeve 502 with the help of the oil pipe. The lubricating sleeve 502 is provided with a sponge ring, which is wrapped around the surface of the screw rod 207. Since the sponge ring has adsorption properties, the sponge ring will absorb the lubricating oil and evenly apply the lubricating oil to the arc surface of the screw rod 207.
[0048] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
