Description

Technical Field

[0001] The utility model relates to the technical field of producing calcium silicate boards, in particular to a molding device for calcium silicate boards. Background Art

[0002] Calcium silicate board is a lightweight board made of siliceous materials, calcium materials, reinforcing fibers, etc. as main raw materials, through pulping, molding, autoclaving and curing processes.

[0003] In order to improve the performance of calcium silicate board, it is necessary to continuously optimize the formula of calcium silicate board. By trying different raw material ratios, types and amounts of additives, calcium silicate boards with different performance characteristics can be prepared. This formula optimization process usually requires small batch production of calcium silicate board for performance testing and evaluation.

[0004] When calcium silicate boards need to be produced in small batches, compression molding is a commonly used molding method. In this method, calcium silicate slurry is pressed into shape through a mold, and calcium silicate boards are obtained after curing.

[0005] Although the molding method has obvious advantages in the small-batch production of calcium silicate boards, the applicable molding equipment still has certain limitations. Some molding equipment is manually operated, with low production efficiency and inconvenient operation. It is easily affected by human factors, resulting in unstable product quality. Although other automatic molding equipment has achieved automated production, due to the strong adhesion between the calcium silicate board and the mold, it is often difficult to remove the calcium silicate board completely from the mold after the calcium silicate board is formed. Summary of the invention

[0006] The utility model aims to provide a calcium silicate board molding device in view of the problems existing in the prior art.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A molding device for a calcium silicate board comprises a frame, a first lifting platform and a second lifting platform, the frame comprises mutually connected columns and a fixed platform, the columns are arranged around the center of the fixed platform, the first lifting platform and the second lifting platform are respectively slidably connected to the columns, the fixed platform is located between the first lifting platform and the second lifting platform, a top mold is arranged on the first lifting platform, a fence is arranged on the fixed platform, the fence is arranged around the top mold, a bottom mold is arranged on the second lifting platform, a positioning groove is arranged on the bottom mold, and the fence is connected to the bottom mold through the positioning groove.

[0009] The utility model controls the top mold and the bottom mold to move toward the fixed platform through the first lifting platform and the second lifting platform, so that the top mold, the bottom mold and the enclosure cooperate to press the calcium silicate slurry into shape. The first lifting platform and the second lifting platform can also be used to control the top mold and the bottom mold to move in the same direction away from the enclosure, so that the top mold and the bottom mold can take the pressed calcium silicate board out of the enclosure, which is convenient for taking the calcium silicate board out of the mold completely.

[0010] Preferably, the projections of the top mold and the bottom mold on the horizontal plane are both rectangular, and rectangular openings are respectively provided on both sides of the enclosure, and the rectangular openings are used for allowing the top mold to pass through the enclosure.

[0011] Preferably, the projected areas of the top mold and the enclosure on the horizontal plane are smaller than the projected area of ​​the bottom mold on the horizontal plane.

[0012] Preferably, the frame further comprises a top platform, a bottom platform and a hydraulic push rod, the top platform and the bottom platform are respectively arranged at two ends of the column, the hydraulic push rod is arranged on the top platform, and the hydraulic push rod is connected to the first lifting platform.

[0013] The first lifting platform is pushed to move by the hydraulic push rod, so that the top mold can complete the pressing action and push the formed calcium silicate board out of the enclosure.

[0014] Preferably, the first lifting platform includes a push plate, a guide column, a guide frame and a connecting rod, the top mold and the guide column are respectively arranged on two sides of the push plate, the guide frame is slidably connected to the column, one end of the connecting rod is fixed on the guide frame, and the other end is slidably connected to the guide column.

[0015] The hydraulic push rod directly pushes the push plate to move. To ensure that the top mold can accurately pass through the enclosure, the push plate is connected to the column through the guide frame, and the guide frame is used to limit the moving trajectory of the top mold.

[0016] When the fixed platform blocks the movement of the guide frame, the guide column enables the push plate to continue to move and enter the enclosure.

[0017] Preferably, the second lifting platform includes a support column and a load-bearing plate, the support column is arranged on the bottom platform, the load-bearing plate is arranged on the support column, the bottom mold is arranged on the load-bearing plate, and the load-bearing plate is slidably connected to the column.

The hydraulic lifting columns are arranged on the bottom platform, and the hydraulic lifting columns are connected to the load-bearing plate through the pneumatic hammer.

[0019] The hydraulic lifting column is used to move the load-bearing plate, and the pneumatic hammer can vibrate the bottom mold. On the one hand, when the calcium silicate slurry is poured into the mold, the continuous vibration promotes the flow of the slurry, so that the slurry is more evenly distributed in the mold. On the other hand, when the calcium silicate board and the bottom mold are separated, the continuous vibration weakens the bonding force between the calcium silicate board and the bottom mold, so that the calcium silicate board can be separated from the bottom mold more smoothly.

[0030] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0032] like Figures 1 to 5 As shown, the specific scheme of the embodiment is as follows: Embodiment 1: A molding device for a calcium silicate board comprises a frame, a first lifting platform 6 and a second lifting platform 7, the frame comprises a top platform 1, a bottom platform 2, a hydraulic push rod 3, a column 4 and a fixed platform 5, the column 4 is arranged around the central axis of the frame, the top platform 1 and the bottom platform 2 are respectively arranged at both ends of the column 4, the fixed platform 5 is arranged on the column 4, and the fixed platform 5 is located between the top platform 1 and the bottom platform 2.

[0033] The first lifting platform 6 and the second lifting platform 7 are respectively slidably connected to the column 4. The first lifting platform 6 is located between the top platform 1 and the fixed platform 5. The second lifting platform 7 is located between the bottom platform 2 and the fixed platform 5. The hydraulic push rod 3 is arranged on the top platform 1, and the hydraulic push rod 3 is connected to the first lifting platform 6.

[0034] The first lifting platform 6 includes a push plate 601, a guide column 602, a guide frame 603 and a connecting rod 604. A top mold 9 is provided on the first lifting platform 6. The piston 301 of the hydraulic push rod 3 is connected to the push plate 601. The guide column 602 is arranged parallel to the column 4. The top mold 9 and the guide column 602 are respectively arranged on two sides of the push plate 601, wherein the push plate 601 is located between the top mold 9 and the piston 301, the guide column 602 and the piston 301 are located on the same side of the push plate 601, and the guide column 602 is arranged around the piston 301.

[0035] The guide frame 603 is slidably connected to the column 4, and the guide frame 603 is arranged around the push plate 601. Connecting rods 604 are respectively provided at the four corners of the guide frame 603. One end of the connecting rod 604 is fixed on the guide frame 603, and the other end is slidably connected to the guide column 602. The guide column 602 is provided with a limit cap at the end away from the push plate 601.

[0036] When the hydraulic push rod 3 drives the push plate 601 to move, the push plate 601 drives the guide frame 603 to move together through the guide column 602 and the connecting rod 604. If the push plate 601 tends to move in the horizontal direction, the guide frame 603 moving along the column 4 will prevent the push plate 601 from moving in the horizontal direction. When the guide frame 603 contacts the fixed platform 5, the guide frame 603 cannot continue to move. At this time, the guide column 602 slides relative to the connecting rod 604, so that the push plate 601 can continue to move a distance until the limit cap of the guide column 602 is stuck on the connecting rod 604.

[0037] The second lifting platform 7 includes a support column 8 and a load-bearing plate.
