Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a molding mold for producing calcium silicate cement board. Background Technology

[0002] Calcium silicate cement board, as a new type of green and environmentally friendly building material, is mainly produced by casting using molds.

[0003] According to prior art, a molding die and manufacturing method for calcium silicate cement board production are disclosed (Announcement No.: CN113043432A), which includes a mold base plate, side support plates, splicing plates, isolation columns and support mechanism. The mold base plate is symmetrically provided with side support plates on both sides, and splicing plates are distributed at both ends of the side support plates. The lower end of the splicing plate is installed on the mold base plate. Isolation columns are evenly provided along the length of each splicing plate, and support mechanism is provided on the isolation columns.

[0004] Existing molds are mainly assembled from a base plate and side plates. During the cement pouring and molding process, heat is released. The bottom of the cement board is in contact with the base plate, and steam curing is set up on the top of the cement board. However, the heat accumulates at the bottom and is difficult to dissipate, resulting in a higher temperature at the bottom of the cement board compared to other areas. This can easily cause hollow areas and cracks, affecting the quality of the cement board, especially for thicker boards.

[0005] Therefore, we propose a molding die for the production of calcium silicate cement boards. Utility Model Content

[0006] The present invention mainly addresses the technical problem of heat accumulation in cement boards by providing a molding die for the production of calcium silicate cement boards.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a molding die for producing calcium silicate cement board, comprising:

[0008] The base and two side panels are detachably connected to the base and form a frame on the top of the base, with a casting cavity inside the frame.

[0009] A cooling structure is installed inside the base to cool the base and the cement board. The cooling structure includes a heat dissipation cavity, a water inlet pipe and a return pipe. The heat dissipation cavity is opened inside the base. The water inlet pipe and the return pipe are both fixedly connected to the base and communicate with the heat dissipation cavity. The water inlet pipe is connected to a water source.

[0010] In a preferred embodiment of this utility model, the side guard is a plate with an L-shaped horizontal cross-section, the size of the side guard is smaller than the size of the base, and the base is a rectangular plate.

[0011] In a preferred embodiment of this utility model, a skirt is fixedly installed at the bottom of the base, and the skirt has several mounting holes with bolts installed in the mounting holes. The bolts are threadedly connected to the base.

[0012] In a preferred embodiment of this utility model, a plurality of reinforcing ribs are fixedly provided at the top of the skirt, the reinforcing ribs are fixedly connected to the side guard, and an installation hole is provided between two adjacent reinforcing ribs.

[0013] In a preferred embodiment of this utility model, the cooling structure further includes guide ribs, and a plurality of guide ribs are provided in the heat dissipation cavity. The guide ribs can guide the cooling water supplied by the water inlet pipe so that the cooling water is turned back in the heat dissipation cavity.

[0014] In a preferred embodiment of this utility model, the heat dissipation cavity is a rectangular groove, and the water inlet pipe and the return pipe are respectively fixedly installed on opposite sides of the base. Both the water inlet pipe and the return pipe extend through the side wall of the base into the heat dissipation cavity.

[0015] In a preferred embodiment of this utility model, the guide rib is a rectangular plate, the guide rib is at the same height as the heat dissipation cavity, one end of the guide rib is fixedly connected to the inner wall of one side of the base, the other end of the guide rib extends inclinedly toward the inner wall of the other side of the base, a gap is left between the end of the guide rib and the inner wall of the base, and several guide ribs are arranged at intervals on the inner walls of opposite sides of the base.

[0016] This utility model provides a molding die for producing calcium silicate cement boards. It has the following beneficial effects:

[0017] 1. This is a molding die for producing calcium silicate cement board. By connecting the inlet pipe to a water source and the return pipe to a water tank, a water pump can be installed in the water tank to circulate water through the pump. Cooling components such as radiators also need to be installed in the water tank, which will not be elaborated here. The circulating water removes heat from the base and the bottom of the cement board, increasing the heat dissipation rate of the bottom of the cement board, inhibiting heat accumulation at the bottom of the cement board, and reducing the probability of the cement board quality being affected by excessive temperature difference. With the help of appropriate steam curing equipment, the quality of the cement board can be improved.

[0018] 2. This calcium silicate cement board production molding mold forms a rectangular frame by placing two side panels diagonally. Bolts are inserted into the mounting holes and tightened with the base, thereby pressing the skirt against the top surface of the base. Concrete is then poured inside the rectangular frame to form a cement board. For demolding, the bolts and two base panels are removed, facilitating assembly and demolding. The L-shaped side panels can stand upright on the top surface of the base without tipping over during assembly. Compared to a frame formed by four separate panels, this solution optimizes the assembly process and improves efficiency.

[0019] 3. This calcium silicate cement board production molding die uses multiple guide ribs. On the one hand, the guide ribs can guide the water, causing the water to zigzag back and forth between adjacent guide ribs, increasing the water travel distance and improving the contact surface area between the base and the water. On the other hand, the design of the guide ribs being at the same height as the heat dissipation cavity can support the inner bottom surface of the base, ensuring the overall load-bearing strength of the base and preventing the base from collapsing due to the heat dissipation cavity after the concrete is poured.

[0026] A molding die for producing calcium silicate cement board, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, it includes:

[0027] The base 10 and two side panels 11 are detachably connected to the base 10 and form a frame on the top of the base 10. The frame has a casting cavity inside. The side panels 11 are L-shaped plates with a horizontal cross section. The size of the side panels 11 is smaller than that of the base 10. The base 10 is a rectangular plate. A skirt 12 is fixedly installed at the bottom of the base 10. The skirt 12 has several mounting holes 14. Bolts are installed in the mounting holes 14 and are threaded to the base 10. Several reinforcing ribs 13 are fixedly installed at the top of the skirt 12. The reinforcing ribs 13 are fixedly connected to the side panels 11. A mounting hole 14 is provided between two adjacent reinforcing ribs 13.

[0028] In this design, the top of the base 10 can be provided with threaded holes for mounting bolts. By placing two side blocks 11 diagonally to form a rectangular frame, the bolts are inserted into the mounting holes 14 and fastened to the base 10, thereby pressing the skirt 12 against the top surface of the base 10. Concrete is then poured inside the rectangular frame to form a cement slab. During demolding, the bolts and the two base blocks 10 can be removed, which facilitates assembly and demolding. The L-shaped side blocks 11 can stand upright on the top surface of the base 10 without tipping over during assembly. Compared to a frame formed by four separate plates, this design optimizes the assembly process and improves efficiency.

[0029] like Figure 2 , Figure 4 and Figure 5 As shown, a cooling structure is installed inside the base 10 to cool the base 10 and the cement board. The cooling structure includes a heat dissipation cavity 20, a water inlet pipe 21, and a return pipe 22. The heat dissipation cavity 20 is opened inside the base 10. The water inlet pipe 21 and the return pipe 22 are both fixedly connected to the base 10 and communicate with the heat dissipation cavity 20. The water inlet pipe 21 is connected to a water source. The cooling structure also includes guide ribs 23. Several guide ribs 23 are arranged inside the heat dissipation cavity 20. The guide ribs 23 can guide the cooling water supplied by the water inlet pipe 21 so that the cooling water is refluxed within the heat dissipation cavity 20. The heat dissipation cavity 20 is rectangular. The inlet pipe 21 and return pipe 22 are fixedly installed on opposite sides of the base 10. Both the inlet pipe 21 and return pipe 22 extend through the side wall of the base 10 into the heat dissipation cavity 20. The guide rib plate 23 is a rectangular plate with the same height as the heat dissipation cavity 20. One end of the guide rib plate 23 is fixedly connected to the inner wall of one side of the base 10, and the other end of the guide rib plate 23 extends inclinedly towards the inner wall of the other side of the base 10. There is a gap between the end of the guide rib plate 23 and the inner wall of the base 10. Several guide rib plates 23 are arranged at intervals on the opposite sides of the inner wall of the base 10.

[0030] In this design, considering that the concrete molding process generates heat, and the bottom of the cement slab, i.e. the contact point between the cement slab and the top surface of the base 10, is the most difficult place for heat to be dissipated, in order to avoid blistering, hollowing, and cracking of the cement slab due to excessive temperature difference, the water inlet pipe 21 is connected to a water source, and the return pipe 22 is connected to a water tank. A water pump can be installed in the water tank to pump water to the water inlet pipe 21 to achieve water circulation. Cooling components such as radiators also need to be installed in the water tank, which will not be elaborated here. The circulating water carries away the heat from the base 10 and the bottom of the cement slab, increases the heat dissipation rate of the bottom of the cement slab, inhibits the accumulation of heat at the bottom of the cement slab, reduces the probability of the cement slab quality being affected by excessive temperature difference, and reduces the impact of the pouring environment temperature on the cement slab.

[0031] With multiple guide ribs 23, the guide ribs 23 can guide the water, causing the water to fold back and forth between two adjacent guide ribs 23, increasing the water travel distance and increasing the contact surface area between the base 10 and the water. Secondly, the design of the guide ribs 23 being at the same height as the heat dissipation cavity 20 can support the bottom surface of the base 10, ensuring the overall load-bearing strength of the base 10 and preventing the base 10 from collapsing due to the heat dissipation cavity 20 after the concrete is poured.

[0032] The working principle of this utility model is as follows: The top of the base 10 can be provided with threaded holes for mounting bolts. By placing two side blocks 11 diagonally to form a rectangular frame, the bolts are placed into the mounting holes 14 and fastened to the base 10. Then, the skirt 12 is pressed against the top surface of the base 10. Concrete is poured inside the rectangular frame to form a cement slab. When demolding, the bolts and the two base blocks 10 can be removed. The water inlet pipe 21 is connected to a water source, and the return pipe 22 is connected to a water tank. A water pump can be installed in the water tank to deliver water to the water inlet pipe 21 to achieve water circulation. Cooling components such as radiators also need to be installed in the water tank, which will not be described in detail here. The circulating water carries away the heat from the base 10 and the bottom of the cement slab. Through multiple guide ribs 23, the guide ribs 23 can guide the water, causing the water to fold back and forth between two adjacent guide ribs 23, increasing the water travel and increasing the contact surface area between the base 10 and the water, thus preventing the heat from accumulating at the bottom of the cement slab.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
