[0002] Foamed cement board is a building material, also known as foamed concrete board or lightweight concrete board. It is mainly composed of cement, water, and foaming agent. During the curing process, it forms a large number of tiny closed pores, which greatly reduces its density and weight. Due to its unique structure, foamed cement board also has a certain sound insulation effect and performs well in terms of fire resistance and water resistance.

[0003] During the production and processing of foamed cement boards, the boards can be demolded once they have completed initial setting and achieved initial strength. Currently, the demolding of foamed cement boards is mostly done by casting wooden boards. When demolding, the wooden boards around the mold are knocked off to achieve the desired effect. However, this demolding method is time-consuming, labor-intensive, and inefficient.

[0004] Therefore, this utility model proposes a rapid demolding mold for cement foamed board to solve the problems existing in the prior art. Utility Model Content

Detailed Implementation

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1-5 As shown in the figure, this embodiment proposes a solution: a quick demolding molding mold for foamed cement board, including a workbench 1, support rods fixedly installed at the top of the workbench 1 near the four corners, a top plate 2 fixedly installed at the top of multiple support rods, a hydraulic cylinder 3 fixedly installed at the center of the top of the top plate 2, the power output shaft of the hydraulic cylinder 3 passing through the inner side of the top plate 2 and fixedly installed with an upper mold 4, multiple positioning rods 5 fixedly installed at the bottom of the upper mold 4, multiple connecting seats 6 provided on the top of the workbench 1, two moving blocks fixedly installed at the bottom of the connecting seats 6, a moving groove for the moving blocks to slide on the top of the workbench 1, a template 7 adapted to the upper mold 4 fixedly installed on the side of the connecting seats 6 near the center of the workbench 1, and a demolding assembly provided at the bottom of the workbench 1 for quick demolding.

[0022] In this implementation case, a release agent is first applied to the template 7 to prevent sticking during demolding. When preparing for injection molding, the hydraulic cylinder 3 drives the upper mold 4 to descend until it closes with the template 7 on the top of the workbench 1 to form a sealed cavity. After the mold closes, the cement foaming slurry is injected into the cavity through the injection pipe until the cavity is filled. After the cement foam board has completed its initial setting, the hydraulic cylinder 3 drives the upper mold 4 to rise and reset, reserving space for subsequent demolding. Through the setting of the demolding component, the formed cement foam board is completely removed from the cavity. At the same time, the connecting seat and template 7 are moved to the outside to separate, which facilitates demolding by the device and eliminates the need for manual force to knock, avoiding damage to the edges and corners of the board caused by traditional knocking.

[0023] Support legs are fixedly installed at the bottom of the workbench 1 near the four corners, and injection pipes are fixedly installed at the top of the upper mold 4 near the front. Workers inject cement foaming slurry into the cavity through the injection pipes.

[0024] A fixing plate 8 is fixedly installed on the top of the workbench 1 and on one side of the connecting seat 6. Two connecting rods 9 are slidably connected to the inner side of the fixing plate 8. The end of the connecting rod 9 away from the fixing plate 8 is fixedly connected to the surface of the adjacent connecting seat 6. The side walls of the two adjacent templates 7 are fitted together. The top of the connecting seat 6 is provided with a positioning hole that matches the positioning rod 5. The guiding effect of the connecting rod 9 and the fixing plate 8 prevents the template 7 from tilting during movement. During the descent of the upper mold 4, the positioning rod 5 at its bottom is accurately inserted into the positioning hole at the top of the connecting seat 6 to achieve the pre-positioning of the upper mold 4 and the template 7, ensuring the consistency of the cavity size.

[0025] The demolding assembly includes a fixed frame 10, the top of which is fixedly connected to the bottom of the workbench 1. A threaded rod 11 is rotatably connected to the inside of the fixed frame 10. A threaded sleeve 12 is fitted onto the surface of the threaded rod 11 and threadedly connected to it. The top of the threaded sleeve 12 passes through the inside of the fixed frame 10 and the bottom of the workbench 1, and a demolding module 13 is fixedly installed thereon. A drive motor 14 for driving the threaded rod 11 to rotate is fixedly installed at the bottom of the fixed frame 10. A notch adapted to the demolding module 13 is opened at the center of the top of the workbench 1. After the cement foam board has completed its initial setting, the drive motor 14 starts and drives the threaded rod 11 to rotate inside the fixed frame 10. The threaded rod 11 and the threaded sleeve 12 are connected by threads to convert the rotational motion into vertical motion. The threaded sleeve 12 slides upward along the inner wall of the fixed frame 10, simultaneously driving the demolding module 13 at the top to push the bottom of the cement foam board upward, so that the device can perform demolding.

[0026] A connecting block 15 is fixedly installed at the bottom center of the connecting seat 6. A hinge rod 16 is rotatably connected to the bottom of the connecting block 15. The end of the hinge rod 16 away from the connecting block 15 is rotatably connected to the surface of the threaded sleeve 12. During the upward movement of the threaded sleeve 12, its surface pulls the connecting block 15 at the bottom of the connecting seat 6 through the hinge rod 16. The connecting block 15 moves laterally along the second movable groove 18 of the worktable 1. The connecting block 15 drives the connecting seat 6 and the template 7 to move along the movable groove in a direction away from the center of the cavity, realizing the automatic opening and closing of the template 7. With the push action of the release module 13, the cement foam board is completely removed from the cavity.

[0027] The inner side of the fixed frame 10 is provided with a first movable groove 17 for the hinge rod 16 to move up and down, and the inner side of the worktable 1 is provided with a second movable groove 18 for the connecting block 15 to slide left and right. The surface of the threaded sleeve 12 is slidably connected to the inner wall of the fixed frame 10. Through the action of the first movable groove 17 and the second movable groove 18, the stability of the movement of the hinge rod 16 is increased.

[0028] The above embodiment discloses a rapid demolding mold for foamed cement boards. During injection molding preparation, the hydraulic cylinder 3 drives the upper mold 4 to descend until it closes with the template 7 at the top of the worktable 1, forming a sealed cavity. The positioning rod 5 at its bottom is precisely inserted into the positioning hole at the top of the connecting seat 6, achieving pre-positioning of the upper mold 4 and the template 7, ensuring consistent cavity dimensions. After the mold closes, the foamed cement slurry is injected into the cavity through the injection pipe until the cavity is filled. After the foamed cement board has initially set, the hydraulic cylinder 3 drives the upper mold 4 to rise and reset, reserving space for subsequent demolding. The drive motor 14 starts and drives the threaded rod 11 to... The fixed frame 10 rotates inside, and the threaded rod 11 and the threaded sleeve 12 are connected by threads to convert the rotational motion into vertical motion. The threaded sleeve 12 slides upward along the inner wall of the fixed frame 10, which simultaneously drives the top demolding module 13 to push the bottom of the cement foam board upward, so that the device can demold. During the upward movement of the threaded sleeve 12, its surface pulls the connecting block 15 at the bottom of the connecting seat 6 through the hinge rod 16. The connecting block 15 drives the connecting seat 6 and the template 7 to move away from the center of the cavity along the moving groove, so as to realize the automatic opening and closing of the template 7. With the pushing action of the demolding module 13, the cement foam board is completely removed from the cavity.
