Description

Technical Field

[0001] This utility model belongs to the field of concrete brick production technology, and more specifically, it relates to a fan-shaped cement concrete extrusion brick mold device. Background Technology

[0002] Cement concrete extruded bricks are made from cement and aggregates as the main raw materials, processed through vibration and pressure or other molding processes. They are used for paving concrete pavements and ground engineering such as sidewalks and city squares. Existing annular fan-shaped cement concrete extruded brick molds require the application of a release agent during the solidification process because the cement concrete can stick to the inside of the mold. During demolding, the cement concrete extruded bricks rub against the inside of the mold, making the inside of the mold rough and prone to sticking to the cement concrete. This causes the release agent to fail and demolding to become difficult. Therefore, an annular fan-shaped cement concrete extruded brick mold device is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a fan-shaped cement concrete extrusion brick mold device. During demolding, the first module, the second module, and the third module separate from the fan-shaped cement concrete extrusion brick, avoiding friction on the inner side of the mold during the ejection process, which would otherwise cause the inner side of the mold to become rough. This solves the problem mentioned in the background art where, during demolding, the cement concrete extrusion brick rubs against the inner side of the mold, causing the inner side of the mold to become rough, which easily leads to adhesion between the brick and the cement concrete, resulting in release agent failure and demolding difficulties.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fan-shaped cement concrete extrusion brick mold device, comprising an upper mold, a middle mold, and a lower mold. A top plate is fixed to the top surface of the middle mold, and a bottom plate is fixed to the bottom surface of the middle mold. Both the top plate and the bottom plate have through grooves on their outer sides. The middle mold has a first mounting groove, a second mounting groove, and two third mounting grooves inside. A first module is slidably connected to the inner side of the first mounting groove, a second module is slidably connected to the inner side of the second mounting groove, and a third module is slidably connected to the inner sides of both third mounting grooves. A groove is provided on one side of the first module, the second module, and the third module. A movable block is slidably connected to the inner side of the groove. A guide rail groove is provided on the outer side of the movable block. The guide rail groove includes two vertical ends and an inclined section. A slider is slidably connected to the inner side of the guide rail groove. A top block with a fan-shaped structure is fixed to the top surface of the lower mold.

[0005] As a preferred embodiment of this utility model, the through groove has a fan-shaped structure.

[0006] As a preferred embodiment of this utility model, one side of the first module has an arc-shaped structure.

[0007] As a preferred embodiment of this utility model, one side of the second module has an arc-shaped structure.

[0008] As a preferred embodiment of this invention, one side of each of the two third modules is inclined.

[0009] As a preferred embodiment of this utility model, the upper end of the movable block penetrates the interior of the top plate and is fixedly connected to the bottom surface of the upper template.

[0010] As a preferred embodiment of this utility model, the slider has a cylindrical structure, and both ends of the slider are fixedly connected to the inner side of the groove.

[0011] This utility model provides a ring-shaped cement concrete extrusion brick mold device, which has the following beneficial effects:

[0012] 1. When demolding, the first, second, and third modules of the annular fan-shaped cement concrete extrusion brick mold separate from the annular fan-shaped cement concrete extrusion brick, avoiding friction on the inner side of the mold during the ejection process. This prevents the inner side of the mold from becoming rough and easily sticking to the cement concrete, causing the release agent to fail and making demolding difficult.

[0013] 2. This ring-shaped cement concrete extrusion brick mold has a reasonable and compact structural design and good performance. Attached Figure Description

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a fan-shaped cement concrete extrusion brick mold device, including an upper mold 1, a middle mold 2, and a lower mold 3. A top plate 4 is fixed to the top surface of the middle mold 2, and a bottom plate 5 is fixed to the bottom surface of the middle mold 2. Both the top plate 4 and the bottom plate 5 have through grooves 6 on their outer sides. The middle mold 2 has a first mounting groove 7, a second mounting groove 8, and two third mounting grooves 9 inside. A first module 10 is slidably connected to the inner side of the first mounting groove 7, a second module 11 is slidably connected to the inner side of the second mounting groove 8, and a third module 12 is slidably connected to the inner sides of each of the two third mounting grooves 9. A [missing information - likely a type of mold] is provided on one side of the first module 10, the second module 11, and the third module 12. There is a groove 13, and a movable block 14 is slidably connected to the inner side of the groove 13. A guide rail groove 15 is opened on the outer side of the movable block 14. The guide rail groove 15 includes two vertical ends and an inclined section. A slider 16 is slidably connected to the inner side of the guide rail groove 15. A top block 17 is fixed on the top surface of the lower template 3. The top block 17 has a fan-shaped structure. The through groove 6 has a fan-shaped structure. One side of the first module 10 has an arc-shaped structure. One side of the second module 11 has an arc-shaped structure. One side of the two third modules 12 has an inclined structure. The upper end of the movable block 14 penetrates the interior of the top plate 4 and is fixedly connected to the bottom surface of the upper template 1. The slider 16 has a cylindrical structure. Both ends of the slider 16 are fixedly connected to the inner side of the groove 13.

[0022] During demolding, the upper mold plate 1 is lifted by an external device, and the lower mold plate 3 is raised upwards. This causes the top block 17 on the lower mold plate 3 to lift the annular fan-shaped cement concrete extrusion brick out of the middle mold plate 2. During this process, the upper mold plate 1 drives the movable block 14 to move upwards. The guide rail groove 15 on the movable block 14 slides past the outside of the slider 16. When the slider 16 passes the inclined section on the guide rail groove 15, it moves outwards and drives the first module 10, the second module 11, and the third module 12 to move outwards along the first mounting groove 7, the second mounting groove 8, and the two third mounting grooves 9, respectively. This separates them from the annular fan-shaped cement concrete extrusion brick, avoiding friction on the inner side of the mold during the ejection process. This prevents the inner side of the mold from becoming rough and easily sticking to the cement concrete, causing the release agent to fail and making demolding difficult.

[0023] The specific usage and function of this embodiment: When demolding, the upper template 1 is lifted by an external device, and the lower template 3 is raised upward, so that the top block 17 on the lower template 3 lifts the annular fan-shaped cement concrete extrusion brick out of the middle template 2. During this process, the upper template 1 drives the movable block 14 to move upward. The guide rail groove 15 on the movable block 14 slides past the outside of the slider 16. When the slider 16 passes through the inclined section on the guide rail groove 15, it moves outward and drives the first module 10, the second module 11 and the third module 12 to move outward along the first mounting groove 7, the second mounting groove 8 and the two third mounting grooves 9 respectively, thereby separating from the annular fan-shaped cement concrete extrusion brick.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
