DETAILED DESCRIPTION

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Please see Figures 1-6 This embodiment provides an inner mold device for preparing cement flue gas ducts, including a base plate 1, side plates 2 hinged to both sides of the base plate 1 via hinges 3, and a top plate 9 connected to the upper end of the base plate 1 via a telescopic tube 20. A sliding rod 5 that can slide back and forth is provided on the upper side of the base plate 1, and an inner mold adjustment assembly is provided on the sliding rod 5. When the sliding rod 5 slides, the inner mold adjustment assembly can drive the side plates 2 to rotate and the top plate 9 to rise and fall. Specifically, as shown... Figures 1-5 As shown, the inner mold adjustment assembly includes horizontal adjustment plates 6 disposed on both sides of the sliding rod 5 and a vertical adjustment plate 10 disposed on the top of the sliding rod 5. S-shaped horizontal guide grooves 14 and vertical guide grooves 15 are respectively formed on the horizontal adjustment plates 6 and 10. A side plate guide shaft 7 is connected to the inner side of the side plate 2 via a horizontal connecting plate 8, with one end of the side plate guide shaft 7 movably inserted into the horizontal guide groove 14. A top plate guide shaft 11 is connected to the lower end of the top plate 9 via a vertical connecting plate 12, with one end of the top plate guide shaft 11 movably inserted into the vertical guide groove 15. As is common knowledge familiar to those skilled in the art, such as... Figure 2 As shown, if the side plate 2 is retracted, the corresponding side plate guide shaft 7 will tilt to a certain extent. Therefore, it is necessary to ensure that the horizontal guide arc groove 14 will not affect the movement of the side plate guide shaft 7. Thus, the width of the horizontal guide arc groove 14 is designed to be greater than the diameter of the side plate guide shaft 7, so as to reserve a certain tilting space for the side plate guide shaft 7. The size of the groove is not described in detail in this application and is a conventional design familiar to those skilled in the art.

[0021] It should be noted that, in order to ensure the sealing of the inner mold after it is supported, as a conventional design, the hinge 3 is a long hinge to ensure the stability of the connection between the side plate 2 and the bottom plate 1. At the same time, corresponding inclined pressure plates 13 are designed at the edges of the top plate 9 and the side plate 2, so that when the inner mold is supported, the inclined pressure plate 13 on the top plate 9 can press against the inclined pressure plate 13 on the top of the side plate 2, which can prevent cement slurry from entering the interior of the inner mold. This design is a conventional design of existing inner molds, and this application will not elaborate on or limit it further.

[0022] Simultaneously, vibration components are also provided on the base plate 1 and the side plate 2 to achieve vibration of the base plate 1 and the side plate 2; the vibration components should be conventional and common structures familiar to those skilled in the art. In this application, combined with Figures 1-3As shown, preferably, the vibration assembly comprises vibration pads 18 arranged on the bottom plate 1 and the side plate 2, which are mainly used for the installation of the vibrator 19 and the transmission of vibration, and the vibrator 19 is arranged on the vibration pads 18, which can be obtained by customized purchase and will not be described herein.

[0023] It should be noted that the installation of the sliding rod 5 is also a conventional design familiar to those skilled in the art, and preferably, in the present application, the sliding rod 5 is arranged on the support frame 4. Figure 3 As shown, a support frame 4 is fixedly arranged on the upper end of the bottom plate 1, and the sliding rod 5 is slidably arranged on the support frame 4, wherein the shape of the support frame 4 will not be specifically described in the present application and can be designed according to actual needs, which is a conventional design familiar to those skilled in the art; specifically, a plurality of inverted U-shaped guide pressure plates 17 are uniformly arranged on the top of the support frame 4, so that the sliding rod 5 penetrates through the guide pressure plates 17 and is slidably connected with the guide pressure plates 17.

[0024] It should be noted that in actual application, the sliding rod 5 can be driven by an external driving member, which is a conventional knowledge familiar to those skilled in the art, such as a telescopic cylinder. Figure 6 As shown, the driving of the sliding rod 5 can be preferably realized by an external telescopic cylinder 16.

[0025] In addition, it should be noted that, as a conventional knowledge familiar to those skilled in the art, in order to ensure the stability of the movement of the side plate 2 and the top plate 9, the number of the horizontal adjusting plate 6 and the vertical adjusting plate 10 should be uniformly arranged with a plurality of plates, which will not be specifically described in the present application. Meanwhile, the direction of the horizontal guide arc groove 14 and the vertical guide arc groove 15 should also be a conventional design familiar to those skilled in the art, which ensures that when the side plate 2 is retracted, the top plate 9 is lowered at the same time, and when the side plate 2 is expanded, the top plate 9 is raised at the same time.

[0026] In actual application, the inner mold is placed inside the outer mold, so that the inner mold is in a raised state as shown in Figure 1 Subsequently, the cement slurry is poured, and when pouring, the vibrator 19 drives the bottom plate 1 and the side plate 2 to vibrate, which plays a role in vibrating and mixing the slurry around the inner mold; after the cement flue is formed, the sliding rod 5 is pushed to rotate the side plate 2 inward and lower the top plate 9, so as to realize the retraction of the inner mold, and at the same time, the vibrator 19 drives the bottom plate 1 and the side plate 2 to vibrate, which can quickly realize the separation of the inner mold surface and the inner wall of the flue, and then the flue can be pulled out.

[0027] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and technical features of the present application. For those skilled in the art, the solutions or features that belong to the prior art or common knowledge are not described in detail in the above embodiments.

[0028] In addition, the technical solutions of the present application are not limited to the above-mentioned embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
