[0041] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0042] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] In the description of this utility model, "a number" refers to one or more, and "a plurality" refers to two or more. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0044] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0045] Ceramic products with concave structures, such as squat toilets and urinals, are generally made using a combination of multiple mold cores, so that the mold core corresponding to the concave part can be taken out from the hollow part after the mold core corresponding to the hollow part is taken out, so as to avoid damaging the ceramic body during the demolding process; at the same time, the mold core part of the mold may have a large demolding area and length. If the whole is demolded, the demolding force will be very large, resulting in difficulty in demolding and easy damage to the mold. By using multiple mold cores, the demolding force can be dispersed during mold separation, making the demolding process smoother and reducing the risk of mold damage.

[0046] Because the raw materials for ceramics are soil with different components, the soil has extremely poor fluidity and is difficult to inject directly into the mold. Generally, a large amount of water is added to the soil to form a slurry, which is then injected into the mold in the form of a slurry. However, the slurry in the mold needs to be drained before it can be formed into a ceramic body. Generally speaking, a material with water absorption and a certain hardness is used as the mold core, such as gypsum. Gypsum can absorb the water in the slurry, allowing the ceramic body to be formed in the mold. However, because the mold core is divided into multiple pieces, some large and some small, during the molding process of the ceramic body, the small mold core can only absorb a limited amount of water. When the small mold core is full of water, the water in the part of the ceramic body formed by the small mold core cannot be further drained, resulting in a thinner thickness of the ceramic body after molding, or even the ceramic body cannot be molded. The size of the small mold core is considered to be difficult to demold. If the size of the small mold core is further increased, it will make it more difficult to demold the ceramic body.

[0047] Reference Figures 1 to 4As shown, the embodiment of the first aspect of the present invention proposes an exhaust structure for a first mold 1000 of a microporous high-pressure resin mold, and the exhaust structure includes: a first connecting piece 100 and a second connecting piece 200. The first connecting piece 100 is used to be installed on the first body 1100, and the first connecting piece 100 is provided with a first connecting channel 110, and the first connecting channel 110 is connected to the interior of the first body 1100. The second connecting piece 200 is used to be installed on the second body 1200, and the second connecting piece 200 can be inserted into the first connecting channel 110, and has a second connecting channel 210 that can be connected to the first connecting channel 110, wherein the second connecting piece 200 is configured as follows: when the second body 1200 is installed on the first body 1100, the second connecting piece 200 is inserted into the first connecting channel 110, and the second connecting channel 210 is connected to the first connecting channel 110. The second body 1200 is connected to the first body 1100 through the first connecting channel 110 and the second connecting channel 210, so that the moisture in the second body 1200 can be smoothly discharged into the first body 1100, and the second body 1200 can maintain dynamic drainage. After the microporous high-pressure resin mold is injected with mud, the second body 1200 can continuously absorb the moisture in the ceramic green body and discharge the water through the second connecting channel 210 and the first connecting channel 110, so that the molding thickness of the ceramic green body is more uniform and the molding quality is higher.

[0048] It should be noted that the application scope of the present invention includes but is not limited to: squat toilet molds, urinal molds, toilet molds, etc. As long as the ceramic body is formed by mud and a microporous high-pressure resin mold with a detachable mold core is used, it is within the protection scope of the present invention.

[0049] In this embodiment, the first connecting member 100 is cylindrical and has a first connecting channel 110 that is axially connected and extends through the first connecting member 100. The first connecting channel 110 is a through hole and may be cylindrical in shape. As another embodiment, the first connecting member 100 may be in the shape of a rectangular column, a triangular column, or other shapes. The inner circumference of the first connecting channel 110 may also be a cylindrical surface, a rectangular surface, or other shaped surfaces. The present invention does not limit the specific shapes of the first connecting member 100 and the first connecting channel 110. However, for cost considerations, shapes with edges are more difficult to process, resulting in increased processing costs. Therefore, cylindrical shapes and their derivative shapes (such as elliptical cylinders) are generally selected, as their manufacturing process is more mature and the processing cost is lower.

[0050] The second connecting member 200 is needle-shaped, and a portion of the second connecting member 200 is inserted into the first connecting channel 110, so that the second connecting channel 210 within the second connecting member 200 is connected to the first connecting channel 110. In this embodiment, the second connecting member 200 is also cylindrical in shape, and the second connecting channel 210 is also cylindrical in shape. Of course, the specific shape of the second connecting member 200 can also be other shapes, and the shape of the second connecting channel 210 can also be other shapes, and this utility model does not impose specific limitations on this. However, for cost considerations, the lowest or lower cost manufacturing method is generally selected to reduce the cost of the second connecting member 200.

[0051] In this embodiment, the first body 1100 is the main portion of the first mold 1000, and the second body 1200 is a small mold core that is detachably connected to the first body 1100. When the second body 1200 is installed on the first body 1100, the first mold 1000 is completed, and the second connecting member 200 of the second body 1200 is inserted into the first connecting channel 110. As another embodiment, the second body 1200 is the main portion of the first mold 1000, and the first body 1100 is a small mold core that is detachably connected to the second body 1200. When the first body 1100 is installed on the second body 1200, the first mold 1000 is completed, and the first connecting channel 110 of the first body 1100 is aligned and inserted into the second connecting member 200. It should be noted that the first body 1100 and the second body 1200 are not limited to being connected to the main portion of the first mold 1000 and the detachable mold core of the first mold 1000. When the main portion of the first mold 1000 is also connected in a split manner and has drainage and / or exhaust requirements, the exhaust structure of the present invention can also be used for communication. In this case, the first body 1100 and the second body 1200 are assembled to form the main portion of the first mold 1000.

[0052] It is worth understanding that the second body 1200 is connected to the first body 1100 through the first connecting piece 100 and the second connecting piece 200, so that the moisture absorbed in the second body 1200 can be discharged in time through the first connecting piece 100 and the second connecting piece 200, so that the overall thickness of the ceramic body after forming is uniform, thereby improving the forming quality of the ceramic body.

[0053] Reference Figure 1 、 Figure 2 and Figure 3As shown in the utility model, in some specific embodiments of the utility model, the exhaust structure further comprises: a protective piece 300 for mounting to the first body 1100, the protective piece 300 is arranged at one end of the first communication piece 100, the protective piece 300 is used for protecting one end of the first communication piece 100 and has a guide hole 310 aligned with the first connecting channel 110; wherein the second communication piece 200 is configured to: when the second body 1200 is mounted to the first body 1100, the second communication piece 200 is inserted into the guide hole 310 and the first connecting channel 110 in sequence.

[0054] It is worth understanding that the one end of the first communication piece 100 is protected by the protective piece 300, so that the second communication piece 200 and the first communication piece 100 can be inserted and mounted more times, the service life of the first communication piece 100 and the second communication piece 200 is improved, and the replacement cost is reduced.

[0055] In the embodiment, the protective piece 300 is a steel product, the first communication piece 100 is a rubber product, and the second communication piece 200 is also a steel product. The protective piece 300 is in a cylindrical shape and has a closed end face, the closed end face is sleeved on one end of the first communication piece 100, and the guide hole 310 aligned with the first connecting channel 110 is arranged. Wherein, the protective piece 300 can also be in a hemispherical shape, and is arranged on one end of the first communication piece 100.

[0056] Referring to Figure 1 , Figure 2 and Figure 3 As shown in the utility model, in some specific embodiments of the utility model, the protective piece 300 has a guide groove 320, and in the direction from the protective piece 300 to the first communication piece 100, the cross-sectional area of the guide groove 320 perpendicular to the axial direction of the first connecting channel 110 decreases to the communication between the guide groove 320 and the guide hole 310.

[0057] It is worth understanding that the protective piece 300 guides the second communication piece 200 to insert into the guide hole 310 through the guide groove 320, and guides the second communication piece 200 to insert into the first connecting channel 110 through the guide hole 310, realizes the guided insertion of the second communication piece 200 and the first connecting channel 110, so that the second communication piece 200 can be more accurately aligned with the first connecting channel 110, without rubbing the first communication piece 100, and the service life of the first communication piece 100 is improved.

[0058] In this embodiment, the cross-sectional area of ​​the guide groove 320 perpendicular to the axial direction of the first connecting channel 110 decreases in two ways: 1. Continuous decrease, for example, a frustum-shaped shape, with the guide hole 310 located at the small end of the frustum. 2. Intermittent decrease, for example, after the cross-sectional area decreases axially for a certain distance, the cross-sectional area remains constant for a certain distance, then decreases again and remains constant, and this cycle repeats multiple times. After the guide groove 320 decreases, its cross-sectional area becomes the cross-sectional area of ​​the guide hole 310, meaning that the guide groove 320 decreases until it connects with the guide hole 310.

[0059] In other specific embodiments of the present invention, the first connecting piece 100 includes a main cylinder portion 120 and a protective portion provided at one end of the main cylinder portion 120, the protective portion being used to protect one end of the main cylinder portion 120, and the first connecting channel 110 connects the main cylinder portion 120 and the protective portion along the axial direction of the main cylinder portion 120; wherein, the second connecting piece 200 is configured as follows: when the second main body 1200 is installed on the first main body 1100, the second connecting piece 200 passes through the protective portion and the main cylinder portion 120 in sequence.

[0060] It is worth understanding that the protective portion is integrally formed at one end of the main cylinder portion 120 to protect one end of the main cylinder portion 120, thereby improving the protection effect, and the first connecting piece 100 can be directly formed within the first main body 1100, which can eliminate the alignment step of the first connecting piece 100 and the protective piece 300, thereby improving the convenience of installation.

[0061] In this embodiment, the protective part is still a steel product, and the main cylinder part 120 is a rubber product. The protective part and the main cylinder part 120 are integrally formed. The specific connection methods include bonding, hot melt connection or the protective part is pre-placed in the molding mold of the main cylinder part 120. After the main cylinder part 120 is cooled and formed, the protective part and the main cylinder part 120 are connected as one.

[0062] Reference Figure 1 、 Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the second connecting piece 200 is configured such that when the second body 1200 is installed on the first body 1100 , the outer circumferential surface of the second connecting piece 200 is sealed with the inner circumferential surface of the first connecting channel 110 .

[0063] It should be noted that during the molding process of the microporous high-pressure resin mold, the mold is pressurized to accelerate the discharge of water and the molding of the ceramic body, thereby improving production efficiency. After pressurization, mud easily enters the installation gap between the second body 1200 and the first body 1100, and enters the gap between the second connecting member 200 and the first connecting channel 110, causing blockage of the second connecting channel 210 and the first connecting channel 110, thereby affecting normal drainage. If the microporous high-pressure resin mold is not pressurized, the production efficiency of the ceramic body is low.

[0064] It is worth understanding that the sealing between the outer circumference of the second connecting piece 200 and the inner circumference of the first connecting channel 110 makes it difficult for mud to enter the first connecting channel 110 and the second connecting channel 210, thereby allowing the moisture in the second main body 1200 to be discharged smoothly, making drainage more convenient.

[0065] Reference Figure 1 、 Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the first connecting piece 100 is elastic and sealing, and the radial dimension of the first connecting channel 110 is smaller than the radial dimension of the outer periphery of the second connecting piece 200; wherein, the second connecting piece 200 is configured as follows: when the second body 1200 is installed on the first body 1100, the first connecting channel 110 elastically expands and squeezes the outer peripheral surface of the second connecting piece 200 to seal the gap between the outer peripheral surface of the second connecting piece 200 and the inner peripheral surface of the first connecting piece 100.

[0066] In this embodiment, the first connecting piece 100 is a rubber product, which is both elastic and sealing. When the second connecting piece 200 is inserted into the first connecting channel 110, the second connecting piece 200 squeezes and expands the first connecting channel 110, so that the inner circumference of the first connecting channel 110 is tightly attached to the outer circumference of the second connecting piece 200, thereby achieving sealing between the first connecting channel 110 and the second connecting piece 200, and being able to withstand the pressure of the mold.

[0067] As another embodiment, the first connecting member 100 can also be made of other materials, such as steel, and an annular sealing ring is provided on the inner circumference of the first connecting channel 110. The number of sealing rings can be one, or multiple sealing rings can be distributed along the axial direction of the first connecting channel 110. When the second connecting member 200 is inserted into the first connecting channel 110, the outer circumference of the second connecting member 200 and the inner circumference of the first connecting channel 110 jointly squeeze the sealing ring, thereby achieving a seal between the first connecting channel 110 and the second connecting member 200. Alternatively, an annular sealing ring is provided on the outer circumference of the second connecting member 200, and the inner circumference of the first connecting channel 110 and the outer circumference of the second connecting member 200 jointly squeeze the sealing ring to achieve a seal.

[0068] Reference Figure 1 、 Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the second connecting member 200 includes a main rod portion 220 and a chamfered portion 230 provided at one end of the main rod portion 220, and the second connecting channel 210 connects the main rod portion 220 and the chamfered portion 230 along the axial direction of the main rod portion 220, and the cross-sectional area of ​​the chamfered portion 230 perpendicular to the main rod portion 220 decreases in the direction away from the main rod portion 220; wherein, the second connecting member 200 is configured as follows: when the second main body 1200 is installed on the first main body 1100, the chamfered portion 230 and the main rod portion 220 are sequentially inserted into the first connecting channel 110.

[0069] It is worth noting that the main rod portion 220 is more easily inserted into the first connecting channel 110 through the chamfered portion 230 , making the installation of the second body 1200 and the first body 1100 more convenient.

[0070] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 1 As shown, in some specific embodiments of the present invention, the first connecting member 100 includes a main cylinder portion 120 and a first embedded portion 130 provided on the outer peripheral surface of the main cylinder portion 120, the first connecting channel 110 is arranged along the axial direction of the main cylinder portion 120, and the first embedded portion 130 protrudes from the outer peripheral surface of the main cylinder portion 120 to connect the first main body 1100; and / or, the second connecting member 200 includes a main rod portion 220 and a second embedded portion 240 provided on the outer peripheral surface of the main rod portion 220, the second connecting channel 210 is arranged along the axial direction of the main rod portion 220, and the second embedded portion 240 protrudes from the outer peripheral surface of the main rod portion 220 to connect the second main body 1200.

[0071] In this embodiment, the second main body 1200 and the first main body 1100 are both gypsum products. The first connecting piece 100 is pre-placed in the molding mold of the first main body 1100 and is molded together with the first main body 1100. The first embedded portion 130 can strengthen the connection effect between the first connecting piece 100 and the first main body 1100, effectively reducing the possibility of the first connecting piece 100 escaping from the first main body 1100, and improving the reliability of use; the second connecting piece 200 is pre-placed in the molding mold of the second main body 1200 and is molded together with the second main body 1200. The second embedded portion 240 can strengthen the connection effect between the second connecting piece 200 and the second main body 1200, effectively reducing the possibility of the second connecting piece 200 escaping from the second main body 1200, and improving the reliability of use.

[0072] Reference Figure 2As shown, a microporous high-pressure resin mold according to an embodiment of the second aspect of the present invention includes a first mold 1000 and a venting structure according to the embodiment of the first aspect. The first mold 1000 includes a first body 1100 and a second body 1200 detachably connected to the first body 1100. The outer surface of the first body 1100 and the outer surface of the second body 1200 together form a portion of the surface of the mold cavity. The second body 1200 has micropores connected to the mold cavity. A first connecting piece 100 is connected to the first body 1100, a second connecting piece 200 is connected to the second body 1200, and a second connecting channel 210 is connected to the micropores, which are used to separate water and soil.

It is worth noting that the microporous high-pressure resin mold can form a ceramic body with uniform thickness through the venting structure, thereby improving the molding quality of the ceramic body.

[0073] In this embodiment, the microporous high-pressure resin mold also includes a second mold. The first mold 1000 and the second mold are combined to form a cavity. The shape of the cavity is the same as that of the ceramic product. Taking a squat toilet as an example, the first body 1100 includes a template portion and a main mold core. The template portion has a molding surface. The main mold core is provided on the molding surface and is generally formed integrally with the template portion. The template portion is used to mold the footrest of the squat toilet and is sealed with the second mold by the edge. The main mold core is used to mold the central pit portion of the squat toilet. The number of second bodies 1200 is multiple and is arranged around the main mold core to respectively mold the water outlet position at the edge of the squat toilet footrest.

[0074] Among them, the first mold 1000 of the microporous high-pressure resin mold is made of microporous resin. The microporous resin itself has micropores, and the diameter of the micropores is usually less than 2nm. This tiny pore size makes the microporous resin highly selective and capable of separation, and can separate water and soil, so that the ceramic body can be dehydrated and formed.

[0075] Reference Figure 3 As shown, in some specific embodiments of the present invention, the first connecting piece 100 is integrally formed in the first body 1100, the second connecting piece 200 is integrally formed in the second body 1200, and a portion of the second connecting piece 200 extends from the outer surface of the second body 1200 to be inserted into the first connecting channel 110 of the first connecting piece 100.

[0076] It is worth understanding that the first connecting piece 100 and the first main body 1100 are integrally formed, so that the connection between the first connecting piece 100 and the first main body 1100 is tighter and more convenient to use; the second connecting piece 200 and the second main body 1200 are integrally formed, so that the connection between the second connecting piece 200 and the second main body 1200 is tighter and more convenient to use.

[0077] Reference Figure 4 Figure 4 Figure 4 Figure 4 As shown, in some specific embodiments of the present invention, a first flow channel is defined inside the first body 1100 , and the first flow channel is connected to the first connecting channel 110 ; a second flow channel is defined inside the second body 1200 , and the second flow channel is connected to the second connecting channel 210 .

[0078] It is worth understanding that, by connecting the second flow channel, the second connecting channel 210, the first connecting channel 110, and the first flow channel in sequence, the water absorbed in the second body 1200 can flow into the first flow channel through the second flow channel, so that the moisture in the second body 1200 is discharged to the position of the first body 1100, so that the second body 1200 is not easily filled with water, and the moisture in the second body 1200 can be discharged dynamically and continuously, thereby improving the molding quality of the ceramic body.

[0079] In this embodiment, the first flow channel is connected to the outside world, so that the water in the second body 1200 can be directly discharged to the outside world. This realizes the drainage of the second body 1200. Among them, the first flow channel is formed by a pipe. When the water in the second body 1200 flows through the first flow channel, it does not enter the first body 1100, but continues to flow along the first flow channel, so that the drainage of the second body 1200 and the drainage of the first body 1100 do not interfere with each other, thereby improving the drainage efficiency of the overall microporous high-pressure resin mold. Among them, the first connecting channel 110 is provided in the template part or the main mold core.

[0080] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
