Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated parts, in particular to a cement prefabricated part mould. Background Art

[0002] Cement precast parts molds are used to make cement precast parts. The cement precast parts cast by the molds are used in projects, which can greatly shorten the construction time of the project, and the quality of cement precast parts is also very good.

[0003] In the prior art, prefabricated parts commonly used in engineering projects include cement prefabricated products such as cement pipes, prefabricated panels, prefabricated drainage ditches and prefabricated piers. In the process of prefabricating the existing prefabricated piers through molds, the mixed cement is generally poured directly into the mold, and then the cement is naturally leveled in the mold. In this way, gaps are easily formed in the cement in the mold, resulting in the cement prefabricated parts being not solid enough, resulting in poor quality of the cement prefabricated parts. Therefore, we propose a cement prefabricated part mold. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. Prefabricated parts used in common projects include cement prefabricated products such as cement pipes, prefabricated panels, prefabricated drainage ditches and prefabricated piers. In the process of prefabricating the existing prefabricated piers through molds, the mixed cement is generally poured directly into the mold, and then the cement is naturally leveled in the mold. In this way, gaps are easily formed in the cement in the mold, which causes the produced cement prefabricated parts to be not solid enough, resulting in poor quality of the cement prefabricated parts.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cement precast part mold comprises a square base, a mold bottom plate of the same shape being installed at the top center of the base, long side templates being symmetrically installed on the front and back sides of the top of the mold bottom plate, and short side templates connected to the edges of the long side templates being installed on the top and on the left and right sides of the mold bottom plate, square extrusion plates being installed on the inner sides of the long side templates and the short side templates, and circular strong suction cups being installed at the corners around the top of the extrusion plates, and strip-shaped connecting rollers being installed on the tops of the strong suction cups, and screw sliders being installed on both sides of the connecting rollers.

[0007] As a preferred solution of the utility model, a synchronous roller is installed laterally near the center of the top of the connecting roller, and squeezing rollers are installed on both sides of the top of the connecting roller, and then a transmission roller fixedly connected to the screw slider is installed on the top of the squeezing roller.

[0008] As a preferred solution of the utility model, the periphery of the screw slider is installed with a rectangular mounting seat fixed to the long side template, and a linear guide rail is opened on the side opposite to the mounting seat and located at the periphery of the screw slider, and a screw rod rotatably connected to the linear guide rail is installed inside the linear guide rail, and the screw slider is slidably connected to the linear guide rail and intersects with the screw rod thread.

[0009] As a preferred solution of the utility model, a first drive motor is installed on the top of the mounting seat, and the output end of the first drive motor passes through the mounting seat and is fixedly connected to the lead screw in the linear guide rail.

[0010] As a preferred solution of the utility model, pull rings are symmetrically installed on both sides of the short side template, and a hook is clamped on the inner side of the pull ring, and a winding rope is installed on the side of the hook away from the pull ring.

[0011] As a preferred solution of the utility model, a rotating shaft is installed horizontally at one end of the winding rope away from the hook, and a fixed seat is installed on the periphery of the rotating shaft, and a second driving motor with an output end fixedly connected to the rotating shaft is installed on the back of the fixed seat.

[0012] The technical effect of adopting the above further scheme is: the second driving motor can effectively drive the rotating shaft to rotate, thereby winding the winding rope, and the short side formwork can be effectively separated from the cement precast part by winding the winding rope, so as to facilitate demoulding.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, through the setting of the extrusion plate, the extrusion plate can effectively extrude the long side template, the short side template and the cement precast parts cast in the mold bottom plate, so as to effectively compact the internal cement and discharge the air, so as to ensure the solidity of the cement precast parts and effectively ensure the quality of the cement precast parts. The first driving motor can effectively drive the screw to rotate, and the rotation of the screw can drive the screw slider to move in the linear guide rail. The downward movement of the screw slider can effectively move the transmission roller downward, and the transmission roller can effectively drive the extrusion roller to extrude the connecting roller. The extrusion of the connecting roller can effectively extrude the strong suction cup, so that the four corners of the extrusion plate can be squeezed at the same time by the strong suction cup, so as to ensure that the extrusion plate can stably extrude the cement and ensure the molding effect of the cement precast parts.

[0025] Example 2

[0026] like Figure 1-3 As shown, a synchronous roller 71 is installed laterally near the center of the top of the connecting roller 7, and squeezing rollers 72 are installed on both sides of the top of the connecting roller 7. Furthermore, a transmission roller 73 fixedly connected to the screw slider 8 is installed on the top of the squeezing roller 72, and the squeezing roller 72 can be effectively squeezed through the transmission roller 73.

[0027] The periphery of the screw slider 8 is installed with a rectangular mounting seat 81 fixed on the long side template 3, and a linear guide rail 82 is opened on the side opposite to the mounting seat 81 and located on the periphery of the screw slider 8, and a screw rod 83 rotatably connected to the linear guide rail 82 is installed inside the linear guide rail 82. The screw slider 8 is slidably connected to the linear guide rail 82 and intersects with the thread of the screw rod 83. When the screw rod 83 rotates, it can effectively drive the screw slider 8 to move in the linear guide rail 82.

[0028] A first drive motor 84 is installed on the top of the mounting seat 81 . The output end of the first drive motor 84 passes through the mounting seat 81 and is fixedly connected to the screw rod 83 in the linear guide rail 82 . The first drive motor 84 can effectively provide driving force for the rotation of the screw rod 83 .

[0029] Pull rings 41 are symmetrically installed on both sides of the short side template 4, and a hook 42 is clamped on the inner side of the pull ring 41, and a winding rope 43 is installed on the side of the hook 42 away from the pull ring 41.
