Description

Technical Field

[0001] This utility model relates to the field of ceramic product manufacturing, and in particular to an exhaust structure and a microporous high-pressure resin mold. Background Technology

[0002] Microporous high-pressure resin molds consist of multiple mold cores of varying sizes, each used to mold different parts of the ceramic product. These cores can be removed sequentially, rather than all at once, which is more beneficial for demolding ceramic products with concave structures. However, when slurry is injected into the microporous high-pressure resin mold, the smaller cores tend to quickly absorb water, preventing some of the water from draining properly. This results in uneven thickness of the ceramic body, with some areas being thinner, thus affecting the quality of the ceramic product. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a venting structure that can improve the forming quality of ceramic blanks and extend their service life.

[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] In the description of this utility model, "several" refers to one or more, and "multiple" refers to two or more. The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship between indicated technical features.

[0043] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0044] Ceramic products with concave structures, such as squat toilets and urinals, are generally made using a combination of multiple mold cores. This allows the mold core corresponding to the concave part to be removed from the hollow part after the mold core corresponding to the hollow part is removed, thus avoiding damage to the ceramic blank during demolding. At the same time, the mold core part of the mold may have a large draft area and length. If the mold is demolded as a whole, the demolding force will be very large, making demolding difficult and easily damaging the mold. By making it with multiple mold cores, the demolding force can be distributed during mold separation, making the demolding process smoother and reducing the risk of mold damage.

[0045] Because ceramic raw materials are clays of varying compositions, and clay has extremely poor fluidity, it's difficult to directly inject it into a mold. Generally, a large amount of water is added to the clay to form a slurry, which is then injected into the mold. However, the slurry needs to be drained of water before it can solidify into a ceramic body. Typically, a material with absorbency and a certain degree of hardness is used as the mold core, such as plaster. Plaster absorbs the water from the slurry, allowing the ceramic body to form within the mold. However, because the mold core is divided into multiple pieces of varying sizes, the smaller mold cores can only absorb a limited amount of water during the ceramic body forming process. When a small mold core is saturated with water, the water in the portion of the ceramic body formed by that small mold core cannot be drained, resulting in a thinner portion of the ceramic body, or even preventing the ceramic body from forming at all. Furthermore, the size of the small mold core is designed for ease of demolding; if the size of the small mold core is further increased, the demolding of the ceramic body will become even more difficult.

[0046] In related technologies, although there are technical solutions that use a first connecting member inserted into a second connecting member, the second connecting member in this solution is a needle-like structure and the first connecting member is a rubber part. In actual use, when the second connecting member is inserted into the first connecting member, it is easy to cause the shape of the second connecting member to deform, and the first connecting member is also easy to break. Therefore, the service life of this technical solution is limited.

[0047] Reference Figures 1 to 4 As shown, the first aspect of this utility model provides an exhaust structure for a first mold 1000 of a microporous high-pressure resin mold, comprising: a first connecting member 100 and a second connecting member 200. The specific application of the microporous high-pressure resin mold can be squat toilet molds, urinal molds, toilet molds, etc. Of course, the application scope of the microporous high-pressure resin mold includes, but is not limited to, the above-mentioned molds. Any microporous high-pressure resin mold that forms a ceramic blank through slurry and uses a detachable mold core is within the protection scope of this utility model.

[0048] The first connecting member 100 is used to be installed to the first body 1100, and the first connecting member 100 is provided with a first connecting channel 110. The second connecting member 200 is used to be installed to the second body 1200, and the second connecting member 200 includes a second main cylinder portion 220 and an insertion portion 230 provided at one end of the second main cylinder portion 220. The radial dimension of the second main cylinder portion 220 is larger than the radial dimension of the insertion portion 230. The second connecting member 200 has a second connecting channel 210 that passes through the second main cylinder portion 220 and the insertion portion 230. The insertion portion 230 can be inserted into the first connecting channel 110 and can connect the first connecting channel 110 and the second connecting channel 210. The second connecting member 200 is configured such that when the second body 1200 is installed on the first body 1100, the second connecting member 200 is inserted into the first connecting channel 110, and the second connecting channel 210 is connected to the first connecting channel 110.

[0049] In this embodiment, the first connecting member 100 is cylindrical and has a first connecting channel 110 that extends along its axial direction and is axially connected to the first connecting member 100. The first connecting channel 110 is a through hole and its shape can be cylindrical. Alternatively, the first connecting member 100 can also be rectangular, triangular, or other shapes. The inner circumferential surface of the first connecting channel 110 can also be a cylindrical surface, a rectangular surface, or other shapes. This invention does not limit the specific shapes of the first connecting member 100 and the first connecting channel 110. However, due to cost considerations, shapes with sharp edges are more difficult to process, leading to increased processing costs. Therefore, cylindrical shapes and their derivative shapes (elliptical cylinders, etc.) are generally chosen because their manufacturing processes are more mature and their processing costs are lower.

[0050] The second connecting member 200 includes a second main cylinder portion 220 and an insertion portion 230. The second main cylinder portion 220 is cylindrical, but can also be rectangular prism, triangular prism, or other shapes. The insertion portion 230 is located on the end face of one end of the second main cylinder portion 220 and is arranged along the axial direction of the second main cylinder portion 220. The insertion portion 230 is also cylindrical, but can also be rectangular prism, triangular prism, or other shapes. The shape of the insertion portion 230 is adapted to the shape of the first connecting channel 110 so as to be inserted into the first connecting channel 110. The radial dimension of the insertion portion 230 is smaller than the radial dimension of the second main cylinder portion 220. The central axis of the insertion portion 230 is substantially coincident with the central axis of the second main cylinder portion 220. As another embodiment, the central axis of the insertion portion 230 and the central axis of the second main cylinder portion 220 can also be spaced apart. The second connecting channel 210 is a through hole and directly penetrates the insertion part 230 and the second main cylinder part 220 along the central axis of the second main cylinder part 220. The shape of the second connecting channel 210 can be cylindrical, or rectangular, triangular, or other shapes.

[0051] It should be noted that because the radial dimension of the insertion part 230 is smaller than that of the second main cylinder part 220, the insertion part 230 can obtain stable support through the second main cylinder part 220, and the structural strength of the insertion part 230 is higher. At the same time, the radial dimension of the second main cylinder part 220 itself is larger. Even if the second connecting channel 210 is opened inside the second main cylinder part 220, the second main cylinder part 220 can still have high structural strength, making the structural strength of the second main cylinder part 220 higher and less prone to deformation.

[0052] Furthermore, the second connecting channel 210 passes through the insertion portion 230 along its axial direction, and the wall thickness of the insertion portion 230 will be basically uniform. The first connecting member 100 is a rigid component, and the second connecting member 200 is also a rigid component. Rigid components refer to materials with relatively hard structures that are not easily deformed elastically, such as steel. Moreover, the steel first connecting member 100 does not need to consider the maximum pressure that a rubber first connecting member 100 generally needs to withstand. In other words, the steel first connecting member 100 can withstand greater pressure without deforming or breaking. Therefore, the wall thickness of the insertion portion 230 can be selected to be larger to connect with the first connecting channel 110 in the first connecting member 100. When the wall thickness of the insertion portion 230 increases, the structural strength of the insertion portion 230 naturally increases, and the insertion portion 230 is less prone to deformation, resulting in a longer overall service life of the second connecting member 200. The first connecting member 100 is a rigid component, which makes it less prone to damage due to repeated insertions of the insertion part 230, and also extends the service life of the first connecting member 100.

[0053] In this embodiment, the first body 1100 is the main body of the first mold 1000, and the second body 1200 is a small mold core detachably connected to the first body 1100. After the second body 1200 is installed on the first body 1100, a complete first mold 1000 is formed, and the second connecting member 200 of the second body 1200 is inserted into the first connecting channel 110. In another embodiment, the second body 1200 is the main body of the first mold 1000, and the first body 1100 is a small mold core detachably connected to the second body 1200. After the first body 1100 is installed on the second body 1200, a complete first mold 1000 is formed, and the first connecting channel 110 of the first body 1100 is aligned with and inserted into the insertion portion 230 of the second connecting member 200. It should be noted that the first body 1100 and the second body 1200 are not limited to the cooperation between the main body of the first mold 1000 and the detachable mold core of the first mold 1000. When the main body of the first mold 1000 is also a split connection and has drainage and / or venting requirements, the venting structure in this utility model can also be used for connection. In this case, the first body 1100 and the second body 1200 are assembled to form the main body of the first mold 1000.

[0054] It is worth understanding that the second main body 1200 is connected to the first main body 1100 through the first connecting member 100 and the second connecting member 200, so that the water absorbed in the second main body 1200 can be discharged in time through the first connecting member 100 and the second connecting member 200, so that the overall thickness of the ceramic blank is uniform after molding, thereby improving the molding quality of the ceramic blank; the insertion part 230 is supported by the second main cylinder part 220. When the insertion part 230 is inserted into the first connecting channel 110, the overall structural strength of the insertion part 230 is higher, so that the service life of the first connecting member 100 and the second connecting member 200 is longer.

[0055] Reference Figure 3 As shown, in some embodiments of this utility model, the second connecting member 200 is configured such that when the second body 1200 is installed on the first body 1100, the outer peripheral surface of the second connecting member 200 and the inner peripheral surface of the first connecting channel 110 are in a sealed fit.

[0056] It should be noted that during the molding process of the microporous high-pressure resin mold, pressure is applied inside the mold to accelerate water drainage and ceramic green body formation, thereby improving production efficiency. However, after pressurization, slurry can easily enter the installation gap between the second main body 1200 and the first main body 1100, and also enter the gap between the second connecting member 200 and the first connecting channel 110, causing blockages in both the second and first connecting channels, thus affecting normal drainage. If the microporous high-pressure resin mold is not pressurized, the production efficiency of the ceramic green body will be low.

[0057] It is worth understanding that the sealing fit between the outer peripheral surface of the second connecting member 200 and the inner peripheral surface 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 water in the second body 1200 to be discharged smoothly and making drainage more convenient.

[0058] Reference Figure 3 As shown, in some specific embodiments of this utility model, the second connecting member 200 further includes a first sealing ring 240 disposed on the outer peripheral surface of the insertion portion 230; wherein, the first sealing ring 240 is configured such that when the second body 1200 is installed on the first body 1100, the first sealing ring 240 is pressed by the outer peripheral surface of the insertion portion 230 and the inner peripheral surface of the first connecting channel 110.

[0059] It is worth understanding that the gap between the outer peripheral surface of the insertion part 230 and the inner peripheral surface of the first connecting channel 110 is sealed by the first sealing ring 240, thereby achieving a better drainage effect of the second body 1200.

[0060] Reference Figure 3As shown, in some specific embodiments of this utility model, the outer peripheral surface of the insertion part 230 has a sealing ring groove 231, and the first sealing ring 240 is sleeved in the sealing ring groove 231.

[0061] In this embodiment, the first sealing ring 240 is annular and nested within the sealing ring groove 231. A portion of the peripheral surface of the first sealing ring 240 protrudes from the outer peripheral surface of the insertion part 230. When the insertion part 230 is inserted into the first connecting channel 110, the bottom surface of the sealing ring groove 231 of the first sealing ring 240 abuts against the inner peripheral surface of the first connecting channel 110, thereby achieving a sealing effect.

[0062] In some specific embodiments of this utility model, it further includes: a second sealing ring; the first connecting member 100 includes a first main cylinder portion 120, and the second sealing ring is disposed between the first main cylinder portion 120 and the second main cylinder portion 220; wherein, the second sealing ring is configured such that when the second body 1200 is installed on the first body 1100, the second sealing ring is abutted by one end of the first main cylinder portion 120 and one end of the second main cylinder portion 220.

[0063] It is worth understanding that by having the ends of the first main cylinder 120 and the second main cylinder 220 abut against the second sealing ring, the second sealing ring indirectly seals the outer peripheral surface of the insertion part 230 and the inner peripheral surface of the first connecting channel 110, thereby improving the drainage effect of the second main body 1200.

[0064] In this embodiment, the second sealing ring is also annular, and the connection position between the insertion part 230 and the first connecting channel 110 is located inside the second sealing ring. When the second sealing ring is squeezed by the end face of the first main cylinder 120 and the end face of the second main cylinder 220, the second sealing ring deforms, so that the second sealing ring seals the gap between the first main cylinder 120 and the second main cylinder 220.

[0065] Reference Figure 2 As shown, in some specific embodiments of this utility model, the first connecting member 100 includes a first connecting port, a second connecting port, and a guide groove 130 that connect the first connecting channel 110. The guide groove 130 is located on the side of the first connecting port away from the second connecting port and is connected to the first connecting port. The cross section of the guide groove 130 perpendicular to the axial direction of the first connecting channel 110 is defined as the first cross section. Along the direction from the first connecting port to the second connecting port, the area of ​​the first cross section decreases until the guide groove 130 is connected to the first connecting port.

[0066] It is understandable that the guide groove 130 guides the insertion part 230 into the first connecting port, thus providing a guiding function and making the insertion of the insertion part 230 more convenient. In this embodiment, the guide groove 130 is integrally formed into the first connecting member 100, eliminating the need for additional components for guidance. This makes the installation of the first connecting member 100 more convenient and avoids the impact of damage or displacement of additional components, resulting in more reliable use.

[0067] Reference Figure 1 As shown, in some specific embodiments of this utility model, the first connecting member 100 further includes a first main cylinder portion 120 and a first embedding groove 140 disposed on the outer peripheral surface of the first main cylinder portion 120, the first embedding groove 140 being used to connect the first body 1100.

[0068] Reference Figure 1 As shown, in some specific embodiments of this utility model, the second connecting member 200 further includes a second embedding groove 250 disposed on the outer peripheral surface of the second main cylinder portion 220, the second embedding groove 250 being used to connect the second body 1200.

[0069] In this embodiment, the first connecting member 100 is integrally formed with the first body 1100, and the second connecting member 200 is integrally formed with the second body 1200. During the integral forming process, the first connecting member 100 is fitted into the main body material of the first body 1100 via the first embedding groove 140. Part of the main body material of the first body 1100 is embedded in the first embedding groove 140, while another part of the main body material adheres to the outer peripheral surface of the first main cylinder portion 120. This results in a protrusion in the first body 1100 corresponding to the first embedding groove 140, which is embedded within the first embedding groove 140. When the first main cylinder portion 120 is removed, it is stopped by the protrusion, making it difficult for the first connecting member 100 to detach from the first body 1100, thus making the connection between the first connecting member 100 and the first body 1100 more reliable. The second embedding groove 250 in the second connecting member 200 plays the same role as the first embedding groove 140, further enhancing the reliability of the connection between the second connecting member 200 and the second body 1200.

[0070] Reference Figure 3 and Figure 4As shown, a second aspect of this utility model provides a microporous high-pressure resin mold, comprising: a first mold 1000 and an exhaust structure according to the first aspect embodiment. The first mold 1000 includes a first body 1100 and a second body 1200 detachably connected to the first body 1100. The outer surfaces of the first body 1100 and the second body 1200 together form a portion of the surface of the mold cavity. The second body 1200 has micropores communicating with the mold cavity. A first connecting member 100 is connected to the first body 1100, a second connecting member 200 is connected to the second body 1200, and a second connecting channel 210 communicates with the micropores. The micropores are used to separate water and soil. The exhaust structure is configured such that when the second body 1200 is installed on the first body 1100, an insertion part 230 is inserted into the first connecting channel 110, and the second connecting channel 210 communicates with the first connecting channel 110. It is worth understanding that this can produce ceramic blanks with uniform thickness, improving the forming quality of the ceramic blanks.

[0071] In this embodiment, the microporous high-pressure resin mold also includes a second mold. The first mold 1000 and the second mold are joined to form a cavity, the shape of which is the same as that of the ceramic product. Taking a squat toilet as an example, the first body 1100 includes a template part and a main mold core. The template part has a molding surface, and the main mold core is located on the molding surface and is generally integrally formed with the template part. The template part is used to form the foot pedal part of the squat toilet and to seal it with the second mold through its edge. The main mold core is used to form the central pit of the squat toilet. There are multiple second bodies 1200, which are arranged around the main mold core to form the water outlet positions with the foot pedal part of the squat toilet as the edge.

[0072] 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 gives the microporous resin a high degree of selectivity and separation ability, and it can separate water and soil, so that the ceramic body can be dehydrated and formed.

[0073] Reference Figure 4 As shown, in some specific embodiments of this utility model, the first connecting member 100 is integrally formed on the first body 1100, the second connecting member 200 is integrally formed on the second body 1200, and the insertion part 230 extends out of the outer surface of the second body 1200 to be inserted into the first connecting channel 110 of the first connecting member 100.

[0074] It is worth understanding that the first connecting member 100 is integrally formed with the first body 1100, making the connection between the first connecting member 100 and the first body 1100 tighter and more convenient to use; the second connecting member 200 is integrally formed with the second body 1200, making the connection between the second connecting member 200 and the second body 1200 tighter and more convenient to use.

[0075] Reference Figure 4 As shown, in some specific embodiments of this utility model, the first body 1100 has a first flow channel defined inside, and the first flow channel is connected to the first connecting channel 110; the second body 1200 has a second flow channel defined inside, and the second flow channel is connected to the second connecting channel 210.

[0076] It is worth understanding that by sequentially connecting the second flow channel, the second connecting channel 210, the first connecting channel 110, and the first flow channel, the water absorbed in the second body 1200 can flow into the first flow channel through the second flow channel, thereby draining the water in the second body 1200 to the location of the first body 1100. This makes it less likely for the second body 1200 to become saturated with water, and allows for dynamic and continuous drainage of water from the second body 1200, thereby improving the forming quality of the ceramic body.

[0077] In this embodiment, the first flow channel is connected to the outside, allowing moisture in the second body 1200 to be directly discharged to the outside, thus achieving drainage of the second body 1200. The first flow channel is formed by a pipe; when moisture 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. This ensures that the drainage of the second body 1200 and the drainage of the first body 1100 do not interfere with each other, improving the overall drainage efficiency of the microporous high-pressure resin mold. The first connecting channel 110 is located in the template section or the main mold core.

[0078] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
