Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and particularly relates to an assembled window hole mold for precast wall production. Background Technique

[0002] When producing precast walls, a window hole mold will be used. The reservation of the window hole in the precast wall needs to be supported by the window hole mold, and then concrete is poured. After the poured concrete dries, the mold is removed to form a window hole, which is convenient for installing windows on the window hole later.

[0003] Chinese Patent Application No. 202222026665.2 discloses a continuous assembled combined mold for window holes in precast walls. By operating the driving component, the threaded rod in the threaded pipe is finally driven to move, so that the first force-applying rod and the second force-receiving rod are located at an appropriate distance. The first force-applying rod and the second force-receiving rod are connected through the connecting component. During the concrete pouring, the force-applying component and the connecting component can provide good support for the four side support templates and the four corner support blocks, ensuring that the mold will not move. After the concrete solidifies, only need to operate the driving component to make the four threaded rods move towards each other, and pull the four side support templates towards each other through the force-applying component and the connecting component to achieve the purpose of rapid mold removal. When removing the mold as above, the handle will be rotated to drive the bevel gear to rotate, thereby driving the threaded pipe to move, so that the four groups of side support templates move towards the box body at the same time to remove the mold. When the four groups of side support templates move towards the box body at the same time, the side support templates are prone to contact and resist each other, causing the four groups of side support templates to stop moving and unable to continue moving towards the box body. This will affect the disassembly of the mold and reduce the use effect of the mold. For this reason, we propose an assembled window hole mold for precast wall production. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an assembled window hole mold for precast wall production, so as to solve the problem proposed in the above background technique that when the four groups of side support templates move towards the box body at the same time, the side support templates are prone to contact and resist each other, causing the four groups of side support templates to stop moving and unable to continue moving towards the box body. This will affect the disassembly of the mold and reduce the use effect of the mold.

[0005] To achieve the above object, the present utility model provides the following technical solutions: An assembled window opening mold for precast wall production, including a support template, the support template includes a first template, two side templates and a second template, the first template is located on the top of the two side templates, the second template is located on the bottom of the two side templates, an installation mechanism is arranged on the support template, the installation mechanism includes two rotating components, the rotating component includes a rotating shaft and an installation column, a connecting plate is fixedly arranged between the bottom of the installation column and the side surface of the side template, the bottom of the side template is rotatably connected to the second template through the rotating shaft, a moving ring is slidably connected to the outside of the installation column, an L-shaped plate is fixedly arranged on the upper surface of the moving ring, arc grooves are opened on the lower surfaces of both ends of the first template, and a connecting piece for connecting the side template and the first template is arranged on the top of the L-shaped plate.

[0006] Preferably, a baffle for limiting the moving ring is fixedly arranged on the top of the installation column, and the baffle is fixedly connected to the installation column by welding.

[0007] Preferably, the connecting piece includes a T-shaped threaded column, a spiral groove is opened inside the L-shaped plate, the working end of the T-shaped threaded column passes through the inside of the spiral groove and is threadedly connected to the spiral groove, a screw opening is opened on the upper surface of the L-shaped plate, a vertical screw rod is threadedly connected inside the screw opening, and the bottom of the vertical screw rod extends to the surface of the T-shaped threaded column.

[0008] Preferably, two screw holes are further opened at the bottom of the first template, and the working end of the T-shaped threaded column penetrates into the inside of the screw holes.

[0009] Preferably, a threaded groove is opened inside the moving ring, a limiting threaded rod is arranged inside the threaded groove, and the working end of the limiting threaded rod extends to the surface of the installation column.

[0010] Preferably, the limiting threaded rod is threadedly connected to the threaded groove, and a rotating handle is fixedly arranged on the top of the limiting threaded rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] (1) The utility model adopts a designed installation mechanism. During use, the T-shaped threaded column is rotated in a direction away from the first template to disengage its working end from the inside. Then, the two sets of side templates are rotated in opposite directions around the rotating shaft so that the tops of the side templates are no longer in contact with the surface of the first template. Subsequently, the first template and the second template are removed from the prefabricated wall. This avoids the situation in which the four sets of side support templates are easily contacted and abutted against each other when the four sets of side support templates are moved toward the box body at the same time during the traditional mold disassembly. This facilitates the disassembly of the side support templates and improves the use effect of the mold.

[0013] (2) The utility model combines the designed threaded groove, the limiting threaded rod and the rotary handle. When the top of the side template is connected and fixed to the first template through the installation mechanism, the movable ring on the installation column can be limited and fixed. This prevents the movable ring from accidentally hitting the mold during the subsequent concrete pouring process, causing the movable ring to slide on the installation column, resulting in a gap between the first template and the side template, thereby further improving the use effect of the mold.
