Description

Technical Field

[0001] This utility model relates to the field of sanitary ceramics production, specifically to a gypsum board mold. Background Technology

[0002] Existing ceramic products are typically produced through slip casting. The conventional production process involves first assembling a plaster tray and a plaster mold to form a complete molding cavity. Then, prepared clay slurry is injected into the molding cavity of the mold, where it gradually solidifies to form a ceramic embryo. After the ceramic embryo is formed, the mold is opened and the ceramic embryo is removed.

[0003] During the grouting process described above, the plasterboard absorbs moisture from the grout, causing the mud particles to solidify into a mold. However, this moisture absorption results in the plasterboard becoming extremely damp both on its surface and inside. Such damp plasterboards must be dried before further use. Traditionally, the damp plasterboards are manually transported to a specialized drying room. This drying process is time-consuming, and once completely dry, the plasterboards must be transported back to the production workshop for the next grouting cycle. This process is not only inefficient and increases production costs but also consumes a significant amount of manpower and resources.

[0004] To solve the above problems, an air channel is created inside the plaster tray, and an air inlet pipe is connected to the tray. The inner end of the air inlet pipe is connected to the air channel, and the outer end is connected to an air source. High-pressure gas is used to expel the liquid in the air channel and dry the entire tray. However, the surface of the air inlet pipe is smooth and it is easy to fall off the tray, which is very inconvenient. Utility Model Content

[0005] Based on this, and in response to the aforementioned technical problems, this utility model provides a plaster tray mold.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A plasterboard mold includes a molding cavity with an injection hole and an exhaust hole at the bottom. A first main rod and a second main rod are respectively located on the left and right sides of the molding cavity. The front ends of the first and second main rods extend forward into the molding cavity. A first pipe and a second pipe are respectively connected to the rear ends of the first and second main rods. The first and second pipes are bent and intersect. The first and second pipes are flexible pipes. An air inlet pipe is connected to the side of the molding cavity. A first insert rod is inserted into the air inlet pipe, with its front end extending into the molding cavity and intersecting with the second pipe. The mold also includes an air connector located inside the molding cavity and fixed to the air inlet pipe to prevent the air inlet pipe from falling off.

[0008] By employing the above technical solution, an air passage connector is installed inside the molding cavity. This air passage connector is connected to an air inlet pipe. After the gypsum slurry is poured into the molding cavity and solidifies to form a support plate, all rods and tubes except the air inlet pipe can be extracted one by one from the support plate. Interconnected pores naturally form inside the support plate, serving as air channels. The air passage connector securely connects the air inlet pipe to the support plate to prevent it from detaching. Subsequently, the air inlet pipe is connected to an air source, and high-pressure gas smoothly enters the air channels through the air passage connector. This high-pressure gas not only expels liquid from the air channels but also quickly dries the entire support plate. The structure is simple and easy to use.

[0009] In a specific embodiment of this utility model: the air connector includes a connector body, a main sealing ring, a retaining ring, and an anti-detachment ring; the connector body has an air inlet pipe installation channel inside, and the two ends of the air pipe installation channel are respectively provided with a first installation groove and a second installation groove arranged in a ring along the inner wall. The main sealing ring is sealed and installed in the first annular installation groove, and the retaining ring is located in the first annular installation groove and outside the main sealing ring. The inner wall of the second installation groove is a conical surface that is larger on the outside and smaller on the inside. The outer wall of the front end of the anti-detachment ring has a conical surface that matches the second installation groove. The side wall of the anti-detachment ring has a vertical C-shaped cut. The inner wall of the anti-detachment ring has barbs opposite to the insertion direction. One end of the anti-detachment ring extends into the second installation groove of the connector body. A third annular installation groove is provided on the inner wall of the retaining ring, and an auxiliary sealing ring is provided in the third installation groove.

[0010] Using the above structure, the front end of the intake pipe passes sequentially through the retaining ring, auxiliary sealing ring, and main sealing ring before exiting through the second mounting groove. An anti-detachment ring is installed on the outside of the second mounting groove at the front end of the intake pipe. Then, one end of the anti-detachment ring is pushed into the second mounting groove towards the connector body. As the radial pressure of the connector body on the anti-detachment ring increases during insertion, the barbs apply a clamping force to the intake pipe, preventing it from detaching from the air passage connector. By using a retaining ring and an auxiliary sealing ring with the main sealing ring, on the one hand, the retaining ring and the auxiliary sealing ring work together to stabilize the intake pipe; on the other hand, during installation, the auxiliary sealing ring effectively removes debris adhering to the surface of the air pipe, preventing debris from affecting the sealing effect of the main sealing ring.

[0011] In a specific embodiment of this utility model: the connector body has an annular protrusion at the opening near the retaining ring for limiting the retaining ring.

[0012] In a specific embodiment of this utility model: there are multiple first main rods, which are spaced apart, and the number and position of the second main rods, the first tubes and the second tubes correspond one-to-one with the first main rods.

[0013] In a specific embodiment of this utility model: a second insert rod is connected to the rear side of the molding cavity, and the front end of the second insert rod extends into the molding cavity and intersects with all the first tubes.

[0014] In a specific embodiment of this utility model, it further includes a first crossbar, a second crossbar, and a third crossbar. The first crossbar intersects with all the first main bars and its outer end extends out of the forming cavity. The second crossbar intersects with all the second main bars and its outer end extends out of the forming cavity. The third crossbar intersects with all the first main bars and all the second main bars and its two ends extend outward out of the forming cavity.

[0015] In a specific embodiment of this utility model: the bottom of the molding cavity is connected to a curved first horizontal tube and a curved second horizontal tube. The inner ends of the first horizontal tube and the second horizontal tube intersect each other. The first horizontal tube intersects with the innermost first main rod, and the second horizontal tube intersects with the innermost second main rod. Both the first tube and the second horizontal tube are flexible tubes.

[0016] In a specific embodiment of this utility model: multiple support members that support the horizontal tube are distributed at the bottom of the molding cavity.

[0017] In a specific embodiment of this utility model: the first main rod, the second main rod, the first insert rod, the second insert rod, the first crossbar, the second crossbar, and the third crossbar are all metal rods.

[0018] In summary, this invention utilizes an air passage connector within the molding cavity, which connects to an air inlet pipe. After the plaster slurry solidifies within the molding cavity to form a support plate, all rods and tubes except the air inlet pipe can be extracted one by one from the support plate. Interconnected pores naturally form inside the support plate, serving as air channels. The air passage connector securely connects the air inlet pipe to the support plate, preventing it from detaching. Subsequently, the air inlet pipe connects to an air source, allowing high-pressure gas to smoothly enter the air channels from the air inlet pipe and through the air passage connector. This high-pressure gas not only expels liquid from the air channels but also rapidly dries the entire support plate, resulting in high efficiency. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 As shown, this utility model is a plasterboard mold. The mold 10 has a plasterboard forming cavity 11, and a grouting hole 12 and a venting hole 13 are provided at the bottom of the forming cavity 11. The grouting hole 12 is used to inject plaster slurry into the forming cavity 11, and the venting hole 13 is used to vent air during the pouring of plaster slurry. A first main rod 21 and a second main rod 22 are respectively located on the left and right sides of the forming cavity 11. The front ends of the first main rod 21 and the second main rod 22 extend forward into the forming cavity 11, and a first pipe 23 and a second pipe 24 are respectively connected to the rear ends of the first main rod 21 and the second main rod 22. The first pipe 23 and the second pipe 24 are bent and intersected. Both the first pipe and the second pipe are flexible pipes. An air inlet pipe 251 is connected to the side of the forming cavity. A first insert rod 26 is inserted into the air inlet pipe 251. The front end of the first insert rod 26 extends into the forming cavity and intersects with the second pipe 24.

[0027] It also includes an air passage connector 25 located inside the molding cavity to prevent the air inlet pipe 251 from falling off. The air passage connector 25 is fixed to the air inlet pipe 251.

[0028] Combination Figure 3As shown, in this embodiment, the air connector 25 includes a connector body 252, a main sealing ring 253, a retaining ring 254, an auxiliary sealing ring 255, and an anti-detachment ring 256. An air inlet pipe mounting channel 257 is provided inside the connector body 252. A first mounting groove 250 and a second mounting groove 258 are respectively provided at both ends of the air pipe mounting channel 257, arranged annularly along the inner wall. The main sealing ring 253 is sealed and installed in the first mounting groove 250, and the retaining ring 254 is located inside the first mounting groove 250 and outside the main sealing ring 253. The inner wall of the second mounting groove 258 is a tapered surface that is larger on the outside and smaller on the inside. The front end of the anti-detachment ring has a tapered surface on its outer wall that matches the tapered surface of the inner wall of the second mounting groove. The side wall of the anti-detachment ring 256 has a vertical C-shaped cut, and the inner wall of the anti-detachment ring 256 has barbs 2561 opposite to the insertion direction. One end of the anti-detachment ring extends into the second mounting groove 258 of the connector body. Additionally, an annular protrusion 2541 for limiting the position of the retaining ring 254 is provided at the opening of the connector body 252 near the retaining ring 254. Furthermore, an annular third mounting groove 259 is provided on the inner wall of the retaining ring 254. The auxiliary sealing ring 255 is located within the third mounting groove 259.

[0029] During assembly, the front end of the intake pipe is passed through the retaining ring, auxiliary sealing ring, and main sealing ring in sequence, and then exits through the second mounting groove. On the outside of the second mounting groove, the anti-detachment ring is installed on the outside of the front end of the intake pipe through the side wall opening. Then, one end of the anti-detachment ring is pushed into the second mounting groove towards the connector body. As the radial extrusion force of the connector body on the anti-detachment ring increases during the insertion process, the anti-detachment ring deforms due to the presence of the cut, thereby causing the barbs to apply a clamping force to the intake pipe, preventing the intake pipe from falling off the air passage connector.

[0030] In this embodiment, there are three first main rods 21, which are spaced apart. The number and position of the second main rods 22, the first tube 23, and the second tube 24 correspond one-to-one with the first main rods.

[0031] In this embodiment, a second insert 27 is connected to the side of the molding cavity 11. The front end of the second insert 27 extends into the molding cavity 11 and intersects with all the first tubes 23.

[0032] In this embodiment, it also includes two first crossbars 28, two second crossbars 29, and three third crossbars 30.

[0033] Two first crossbars 28 are spaced apart, and each first crossbar 28 intersects all the first main bars 21 perpendicularly. The outer end of the first crossbar 28 extends out of the forming cavity 11.

[0034] Two second crossbars 29 are spaced apart, and each second crossbar 29 intersects all the second main bars 22 perpendicularly. The outer end of the second crossbar 29 extends out of the forming cavity 11.

[0035] Three third crossbars 30 are spaced apart, and each third crossbar 30 intersects perpendicularly with all the first main bars 21 and all the second main bars 22. The two ends of the third crossbar 30 extend outward to form a molding cavity 11.

[0036] like Figure 1 and Figure 2 As shown, a curved first horizontal tube 31 and a curved second horizontal tube 32 are connected to the bottom of the molding cavity 11. Both the first horizontal tube 31 and the second horizontal tube 32 are flexible tubes. The inner ends of the first horizontal tube 31 and the second horizontal tube 32 intersect each other. The first horizontal tube 31 intersects with the innermost first main rod 21, and the second horizontal tube 32 intersects with the innermost second main rod 22.

[0037] In this embodiment, there are five first horizontal tubes 31, which are spaced apart along the axial direction. The number and position of the second horizontal tubes 32 correspond one-to-one with the first horizontal tubes 31.

[0038] like Figure 1 and Figure 4 As shown, in this embodiment, the bottom of the forming cavity 11 is provided with a plurality of support members 33 that support the horizontal tube.

[0039] In this embodiment, the first tube 23, the second tube 24, the first horizontal tube 31, and the second horizontal tube 32 are all rubber tubes.

[0040] In this embodiment, the first main rod 21, the second main rod 22, the first insert rod 26, the second insert rod 27, the first crossbar 28, the second crossbar 29, and the third crossbar 30 are all metal rods.

[0041] The above describes the plaster tray mold of this utility model. When manufacturing the tray, firstly, all the first main rods 21 and second main rods 22 are inserted into the molding cavity 11. Then, all the first tubes 23 and second tubes 24 are respectively fitted onto the corresponding first main rods 21 and second main rods 22, and the corresponding first tubes 23 and second tubes 24 are bent and intersected. Next, the second insert rod 27 is inserted into the molding cavity 11 and intersected with all the first tubes 23. Then, the first crossbar 28, the second crossbar 29, and the third crossbar 30 are inserted into the molding cavity 11, with the first crossbar 28 intersecting with all the first main rods 21, and the second crossbar 29 intersecting with all the second main rods 22. Next, all the bent first horizontal tubes 31 and bent second horizontal tubes 32 are inserted into the forming cavity 11. The inner end of each first horizontal tube 31 intersects with the inner end of the corresponding second horizontal tube 32. Furthermore, the first horizontal tube 31 intersects with the innermost first main rod 21, and the second horizontal tube 32 intersects with the innermost second main rod 22. Then, as follows... Figure 5 The middle cover plate 9 is closed with the mold 10. After being rotated 180°, gypsum paste is injected into the molding cavity 11 through the grouting hole 12.

[0042] During the entire assembly process, all intersecting points can be temporarily secured with ropes. After the plaster mortar is poured into the molding cavity and solidifies to form a support plate, all rods and tubes can be easily pulled out one by one from the support plate. Interconnected pores will naturally form inside the support plate, and these pores form air passages.

[0043] In addition, during the entire assembly process, the air inlet pipe 251 is inserted into the molding cavity 11, with its outer end extending out of the cavity. The air passage connector 25 is placed inside the molding cavity 11 and connected to the inner end of the air inlet pipe 251. The front end of the first insert 26 is passed through the air passage connector 25 and the air inlet pipe 251, intersecting with all the second pipes 24. After the tray has solidified, the first insert is removed, while the air passage connector 25 and the air inlet pipe 251 remain inside the tray. The air inlet pipe 251 is connected to a gas source, allowing high-pressure gas to easily enter the air passage via the air inlet pipe 251 and the air passage connector 25.

[0044] As can be seen from the above detailed description, in this utility model, an air passage connector is provided inside the molding cavity. This air passage connector is connected to the air inlet pipe. After the gypsum slurry is poured into the molding cavity and solidifies to form a support plate, all rods and tubes except the air inlet pipe can be pulled out one by one from the support plate. Interconnected pores will naturally form inside the support plate, which will serve as air channels. The air passage connector fixes the air inlet pipe to the support plate to prevent the air inlet pipe from falling off. Afterwards, the air inlet pipe is connected to an air source, and high-pressure gas smoothly enters the air channels from the air inlet pipe and through the air passage connector. Using high-pressure gas not only removes liquid from the air channels but also quickly dries the entire support plate, resulting in high efficiency.

[0045] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
