[0002] The microporous high-pressure resin mold includes multiple mold cores, which are large and small and are used to mold different parts of the ceramic product. The multiple mold cores can be taken out one by one without taking them out together, which is more conducive to demolding ceramic products with concave structures. However, when the slurry is injected into the microporous high-pressure resin mold, the small mold cores tend to absorb water quickly, resulting in part of the water in the slurry being unable to be discharged smoothly, making the thickness of the ceramic body uneven and the thickness of some parts thin, affecting the quality of the ceramic product.

[0043] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the 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 should not be understood as a limitation on the present invention.

[0045] In the description of the present invention, "a number" refers to one or more than one, and "a plurality" refers to two or more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood 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.

[0046] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. 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.

[0047] 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 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.

[0048] Because the raw materials of ceramics are soils of different components, the fluidity of the soil is extremely poor and it is difficult to inject directly into the mold. Generally, a large amount of water is added to the soil to form mud, which is injected into the mold in the form of mud. However, the mud 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 a mold core, such as a microporous resin. The microporous resin can absorb the water in the mud, so that the ceramic body is formed in the mold. However, because the mold core is divided into multiple pieces, and some are large and some are small, during the molding process of the ceramic body, the small mold core can absorb limited 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 discharged, which will cause the thickness of the part of the ceramic body to be thin after molding, and even the ceramic body cannot be molded; and the size of the small mold core is due to the difficulty of demolding. If the size of the small mold core is further increased, it will increase the difficulty of demolding the ceramic body.

[0049] Reference Figures 1 to 9 As shown, an embodiment of the present invention provides a microporous high-pressure resin mold, including: a first mold 1000 and a second mold, the first mold 1000 includes a first main body 1100 and a second main body 1200 detachably connected to the first main body 1100, the first main body 1100 includes a first mounting surface 1110 and a first flow channel 1120 connected to the first mounting surface 1110, the second main body 1200 includes a second mounting surface 1210 and a second flow channel 1220 connected to the second mounting surface 1210, wherein one of the first main body 1100 and the second main body 1200 forms a main body portion, wherein The other forms a core part, the flow channel within the main body part is connected to the outside world, and the flow channel within the core part is connected to the micropores within the core part; the second mold is used to form a mold cavity with the first mold 1000, the micropores are connected to the mold cavity, and the micropores are used to separate water and soil; wherein, the second main body 1200 is configured as follows: when installed on the first main body 1100, the second mounting surface 1210 is installed on the first mounting surface 1110, the second flow channel 1220 is connected to the first flow channel 1120, and the connecting position is sealed relative to the mold cavity, so that the first flow channel 1120 and the second flow channel 1220 can drain water independently.

[0050] It should be noted that the microporous high-pressure resin molds in the present invention include but are not limited to: squat toilet molds, urinal molds, toilet molds, etc. As long as the microporous high-pressure resin molds are formed by slurry ceramic blanks and use detachable mold cores, they are all within the scope of protection of the invention. Among them, taking the squat toilet mold as an example, the concave structure of the squat toilet refers to: the part where the footrest part of the squat toilet intersects with the concave basin body and is used for water outlet. This part needs to hide the water outlet. The footrest part will extend partly to the top of the concave basin body to form a concave structure. The extended part of the footrest part will make it inconvenient to demold the core forming the concave basin body.

[0051] Specifically, the second body 1200 is detachably connected to the first body 1100 to form the first mold 1000, so as to facilitate the demolding of the ceramic product with the concave structure by the microporous high-pressure resin mold, wherein the first body 1100 is the main part of the first mold 1000 and has a main mold core, the first flow channel 1120 is connected to the outside world, and the second body 1200 is the mold core part detachably connected to the first body 1100. The number of the second bodies 1200 can be one or more, and the number and position of the first flow channel 1120 correspond to the number and position of the second flow channel 1220 in the second body 1200. In this embodiment, there are four second bodies 1200, each of which is provided with only one second flow channel 1220. The four second bodies 1200 surround the main mold core in the first body 1100. When all the second bodies 1200 are installed on the first body 1100, a complete first mold 1000 is formed. The second flow channel 1220 in each second body 1200 is aligned with the corresponding first flow channel 1120, so that the water discharged from the second body 1200 can flow into the first flow channel 1120 along the second flow channel 1220 and flow out to the outside through the first flow channel 1120. The second body 1200 may also be provided with two or more second flow channels 1220.

[0052] As another embodiment, the second body 1200 is the main part of the first mold 1000 and has a main mold core, the second flow channel 1220 is connected to the outside world, and the first body 1100 is the mold core part detachably connected to the second body 1200. When the first body 1100 is installed on the second body 1200, a complete first mold 1000 is formed, and the first flow channel 1120 of the first body 1100 is aligned with the second flow channel 1220, so that the moisture discharged from the first body 1100 can flow into the second flow channel 1220 along the first flow channel 1120, and flow out to the outside world through the second flow channel 1220.

[0053] In addition, in this embodiment, the flow channel of the core part is connected to the micropores within the core part, so that the moisture of the mud in the mold cavity can enter the flow channel within the core part through the micropores within the core part to flow along the flow channel within the core part. Taking the first body 1100 as the main body part and the second body 1200 as the core part as an example, the second flow channel 1220 is connected to the second body 1200, and the moisture in the second body 1200 directly enters the second flow channel 1220, and is discharged into the first flow channel 1120 along the second flow channel 1220, and then is discharged to the outside along the first flow channel 1120; taking the first body 1100 as the core part and the second body 1200 as the main body part as an example, the first flow channel 1120 is connected to the first body 1100, and the moisture in the first body 1100 directly enters the first flow channel 1120, and is discharged into the second flow channel 1220 along the first flow channel 1120, and then is discharged to the outside along the second flow channel 1220.

[0054] The flow channel in the main body part can be connected to the micropores in the main body part, or can be isolated from the micropores in the main body part. Taking the first main body 1100 as the main body part as an example, if the first flow channel 1120 is connected to the micropores of the first main body 1100, then the water in the first main body 1100 can enter the first flow channel 1120 along the micropores therein, and the water in the second main body 1200 can enter the second flow channel 1220 along the micropores therein, and the water in the first main body 1100 and the second main body 1200 are discharged to the outside together along the first flow channel 1120 and the second flow channel 1220; if the first flow channel 1120 is not connected to the micropores in the first main body 1100, then only the water in the second main body 1200 is discharged along the flow channel, that is, only the water in the core part is discharged along the direction of the second flow channel 1220, the first flow channel 1120, and the outside world, and only the water in the core part is discharged, and the drainage of the core part is more efficient. When the second body 1200 is the main body part and the first body 1100 is the core part, if the second flow channel 1220 is connected with the micropores in the second body 1200, the moisture in the first body 1100 and the second body 1200 is discharged together along the first flow channel 1120 and the second flow channel 1220; if the second flow channel 1220 is not connected with the micropores in the second body 1200, only the moisture in the first body 1100 is discharged along the first flow channel 1120 and the second flow channel 1220.

[0055] Specifically, the situations when the flow channel of the main body is connected to the main body include: 1. The main body is made of microporous resin material, and the inner peripheral surface of the flow channel of the main body is directly formed by the microporous resin material; 2. The main body is made of microporous resin material, and the flow channel of the main body is formed by a separate pipe, such as a plastic pipe, a steel pipe, etc., and the pipe forming the flow channel is provided with a connecting hole connected to the main body and the flow channel. The situations when the flow channel of the main body is not connected to the main body include: the main body is made of microporous resin material, and the flow channel of the main body is formed by a separate pipe, such as a plastic pipe, a steel pipe, etc., and the pipe forming the flow channel is a complete pipe. Among them, the microporous resin material itself has micropores, and the pore size of the micropores is usually less than 2nm. This tiny pore size makes the microporous resin highly selective and has separation ability, and can separate water and soil in the mold cavity of the microporous high-pressure resin mold, so that the ceramic body is dehydrated and formed.

[0056] It should also be noted that during the molding process of the microporous high-pressure resin mold, the microporous high-pressure resin mold will be pressurized to accelerate the discharge of water and the molding of the ceramic body, thereby improving production efficiency. After pressurization, the mud easily enters the gap between the first mounting surface 1110 and the second mounting surface 1210, and enters the first flow channel 1120 and the second flow channel 1220, causing the first flow channel 1120 and the second flow channel 1220 to be blocked, thereby affecting normal drainage. If the microporous high-pressure resin mold is not pressurized, the production efficiency of the ceramic body is low, but the ceramic body can be produced normally.

[0057] In order to improve the production efficiency of the microporous high-pressure resin mold, the connecting position of the first flow channel 1120 and the second flow channel 1220 is set to be sealed relative to the mold cavity, so that the drainage channel formed by the first flow channel 1120 and the second flow channel 1220 exists independently, and the drainage channel is not connected to the mold cavity. When mud is injected into the mold cavity and in the subsequent pressurization process, the mud in the mold cavity is difficult to enter the drainage channel formed by the first flow channel 1120 and the second flow channel 1220, and the moisture in the mud can penetrate into the first body 1100 and the second body 1200, so as to enter the first flow channel 1120 and the second flow channel 1220, and then be discharged to the outside along the first flow channel 1120 and the second flow channel 1220.

[0058] It is worth understanding that the first mold 1000 and the second mold are combined to form a mold cavity, which is connected to the second flow channel 1120 and 1220 through the first flow channel 1120, so that the first flow channel 1120 and the second flow channel 1220 are directly connected to the outside world, so as to discharge the moisture in the first body 1100 and the second body 1200 in time, thereby improving the molding quality of the ceramic body.

[0059] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments of the present invention, the first body 1100 includes a first base portion 1130 and a first connecting piece 1140 connected to the first base portion 1130, the first connecting piece 1140 is provided with a first connecting channel 1141, and the first connecting channel 1141 is connected to the first flow channel 1120; the second body 1200 includes a second base portion 1230 and a second connecting piece 1240 connected to the second base portion 1230, and the second connecting piece 1240 can be inserted into the first connecting channel 1 141, and has a second connecting channel 1241 that can be connected to the first connecting channel 1141, and the second connecting channel 1241 is connected to the second flow channel 1220; wherein the second body 1200 is configured as follows: when installed on the first body 1100, the second connecting piece 1240 is inserted into the first connecting channel 1141, the first connecting channel 1141 is connected to the second connecting channel 1241, and the outer peripheral surface of the second connecting piece 1240 is circumferentially sealed and connected to the inner peripheral surface of the first connecting channel 1141.

[0060] It is worth understanding that the first body 1100 and the second body 1200 are interlocked through the first connecting piece 1140 and the second connecting piece 1240, so that the first connecting channel 1141 is connected to the second connecting channel 1241, so that the first flow channel 1120 is connected to the second flow channel 1220 and the first flow channel 1120 and the second flow channel 1220 are kept sealed relative to the mold cavity. The installation method of the first body 1100 and the second body 1200 is simple and easy to operate, and the actual application of the first flow channel 1120 and the second flow channel 1220 in the mold grouting process is more reliable.

[0061] In this embodiment, the first connecting piece 1140 is cylindrical, and the first connecting piece 1140 has a first connecting channel 1141 that is connected along its axial direction and passes through the first connecting piece 1140 axially. The first connecting channel 1141 is a through hole, and its shape can be cylindrical. As another embodiment, the first connecting piece 1140 can also be rectangular columnar or triangular columnar or other shapes, and the inner circumference of the first connecting channel 1141 can also be cylindrical or rectangular or other shaped circumferences. The present invention does not limit the specific shapes of the first connecting piece 1140 and the first connecting channel 1141. However, for cost considerations, the processing difficulty of the shape with edges is higher, resulting in increased processing costs, so generally cylindrical and its derivative shapes (elliptical cylinder, etc.) are selected, and their manufacturing process is more mature and the processing cost is lower. The second connecting piece 1240 is in the shape of a needle tube, and part of the second connecting piece 1240 is inserted into the first connecting channel 1141, so that the second connecting channel 1241 in the second connecting piece 1240 is connected to the first connecting channel 1141. In this embodiment, the second connecting member 1240 is also cylindrical, and the second connecting channel 1241 is also cylindrical. Of course, the specific shape of the second connecting member 1240 can also be other shapes, and the shape of the second connecting channel 1241 can also be other shapes, which are not specifically limited by the present invention. However, for cost considerations, the lowest or lower cost manufacturing method is generally selected to reduce the cost of the second connecting member 1240.

[0062] Reference Figure 4 and Figure 5 As shown, in some specific embodiments of the present invention, the first main body 1100 also includes a protective member 1150 arranged at one end of the first connecting member 1140, the protective member 1150 is used to protect one end of the second connecting member 1240, the protective member 1150 is used to protect one end of the first connecting member 1140, and has a guide hole 1151 aligned with the first connecting channel 1141; wherein, the second connecting member 1240 is configured as follows: when the second main body 1200 is installed on the first main body 1100, the second connecting member 1240 is inserted into the guide hole 1151 and the first connecting channel 1141 in sequence.

[0063] It is worth understanding that by protecting one end of the first connecting piece 1140 with the protective piece 1150, the second connecting piece 1240 and the first connecting piece 1140 can be plugged in more times, thereby increasing the service life of the first connecting piece 1140 and the second connecting piece 1240 and reducing replacement costs.

[0064] In this embodiment, the protective member 1150 is a steel product, the first connecting member 1140 is a rubber product, and the second connecting member 1240 is also a steel product. The protective member 1150 is cylindrical and has one end face closed, and the closed end face is sleeved on one end of the first connecting member 1140, and is provided with a guide hole 1151 aligned with the first connecting channel 1141. The protective member 1150 can also be hemispherical, so as to cover one end of the first connecting member 1140.

[0065] Reference Figure 4 and Figure 5 As shown, in some specific embodiments of the present invention, the protective member 1150 has a guide groove 1152, and along the direction from the protective member 1150 to the first connecting member 1140, the cross-sectional area of ​​the guide groove 1152 perpendicular to the axial direction of the first connecting channel 1141 decreases until the guide groove 1152 is connected to the guide hole 1151.

[0066] It is worth understanding that the protective member 1150 guides the second connecting member 1240 to be inserted into the guide hole 1151 through the guide groove 1152, and guides the second connecting member 1240 to be inserted into the first connecting channel 1141 through the guide hole 1151, thereby realizing the guided plug-in of the second connecting member 1240 and the first connecting channel 1141, so that the second connecting member 1240 can be more accurately aligned with the first connecting channel 1141 without rubbing against the first connecting member 1140, thereby improving the service life of the first connecting member 1140.

[0067] In this embodiment, the cross-sectional area of ​​the guide groove 1152 perpendicular to the axial direction of the first connecting channel 1141 decreases in the following two cases: 1. Continuous decrease, for example, a truncated cone shape, and the guide hole 1151 is located at the small end of the truncated cone. 2. Intermittent decrease, for example, after the cross section decreases for a certain distance along the axial direction, the cross section remains unchanged for a certain distance along the axial direction, and then decreases again and remains unchanged and repeats multiple times. After the guide groove 1152 decreases, the cross section of the guide groove 1152 is the cross section of the guide hole 1151, that is, the guide groove 1152 decreases until it is connected to the guide hole 1151.

[0068] In some other specific embodiments of the present invention, the first connecting piece 1140 includes a main cylinder portion 1142 and a protective portion provided at one end of the main cylinder portion 1142, the protective portion being used to protect one end of the main cylinder portion 1142, and the first connecting channel 1141 connects the main cylinder portion 1142 and the protective portion along the axial direction of the main cylinder portion 1142; wherein, the second connecting piece 1240 is configured as follows: when the second body 1200 is installed on the first body 1100, the second connecting piece 1240 passes through the protective portion and the main cylinder portion 1142 in sequence.

[0069] It is worth understanding that the protection portion is integrally formed at one end of the main cylinder portion 1142 to protect the one end of the main cylinder portion 1142, thereby improving the protection effect, and the first connecting piece 1140 can be directly formed within the first main body 1100, which can eliminate the alignment step of the first connecting piece 1140 and the protection piece 1150, thereby improving the convenience of installation.

[0070] In this embodiment, the protection part is still a steel product, and the main cylinder part 1142 is a rubber product. The protection part and the main cylinder part 1142 are integrally formed. The specific connection methods include bonding, hot-melt connection or the protection part is pre-placed in the molding mold of the main cylinder part 1142. After the main cylinder part 1142 is cooled and formed, the protection part and the main cylinder part 1142 are connected as one.

[0071] Reference Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the first base portion 1130 and the first connecting piece 1140 are integrally formed, and the second base portion 1230 and the second connecting piece 1240 are integrally formed.

[0072] It is worth understanding that the first base portion 1130 and the first connecting piece 1140 are integrally formed, so that the installation position accuracy of the first connecting piece 1140 relative to the first base portion 1130 is higher, and the second base portion 1230 and the second connecting piece 1240 are integrally formed, so that the installation position accuracy of the second connecting piece 1240 relative to the second base portion 1230 is higher, thereby making the matching accuracy of the first connecting piece 1140 and the second connecting piece 1240 higher.

[0073] In this embodiment, the first connecting member 1140 includes a main cylinder portion 1142 and a first embedded portion 1143 provided on the outer circumference of the main cylinder portion 1142, the first connecting channel 1141 is provided along the axial direction of the main cylinder portion 1142, and the first embedded portion 1143 protrudes from the outer circumference of the main cylinder portion 1142, so as to be connected to the first body 1100. And / or, the second connecting member 1240 includes a main rod portion 1242 and a second embedded portion 1245 provided on the outer circumference of the main rod portion 1242, the second connecting channel 1241 is provided along the axial direction of the main rod portion 1242, and the second embedded portion 1245 protrudes from the outer circumference of the main rod portion 1242, so as to be connected to the second body 1200.

[0074] In this embodiment, the second body 1200 and the first body 1100 are both microporous resin products. The first connecting piece 1140 is pre-placed in the molding mold of the first body 1100 and is molded together with the first body 1100. The first embedded portion 1143 can strengthen the connection effect between the first connecting piece 1140 and the first body 1100, effectively reducing the possibility of the first connecting piece 1140 escaping from the first body 1100, thereby improving the reliability of use; the second connecting piece 1240 is pre-placed in the molding mold of the second body 1200 and is molded together with the second body 1200. The second embedded portion 1245 can strengthen the connection effect between the second connecting piece 1240 and the second body 1200, effectively reducing the possibility of the second connecting piece 1240 escaping from the second body 1200, thereby improving the reliability of use.

[0075] Reference Figure 4 As shown, in some specific embodiments of the present invention, the first connecting piece 1140 is elastic and sealing, and the radial dimension of the first connecting channel 1141 is smaller than the radial dimension of the outer periphery of the second connecting piece 1240; wherein, the second connecting piece 1240 is configured as follows: when the second connecting piece 1240 is inserted into the first connecting channel 1141, the first connecting channel 1141 elastically expands and squeezes the outer peripheral surface of the second connecting piece 1240 to circumferentially seal the gap between the outer peripheral surface of the second connecting piece 1240 and the inner peripheral surface of the first connecting piece 1140.

[0076] In this embodiment, the first connecting piece 1140 is a rubber product, which is both elastic and sealing. When the second connecting piece 1240 is inserted into the first connecting channel 1141, the second connecting piece 1240 squeezes and expands the first connecting channel 1141, so that the inner circumference of the first connecting channel 1141 is in close contact with the outer circumference of the second connecting piece 1240, thereby achieving sealing between the first connecting channel 1141 and the second connecting piece 1240, and being able to withstand the pressurization of the mold.

[0077] Reference Figure 6 and Figure 7 As shown, in some specific embodiments of the present invention, the second connecting piece 1240 includes a main rod portion 1242 and an elastic sealing layer 1243 arranged on the outer peripheral surface of the main rod portion 1242, and the radial dimension of the first connecting channel 1141 is smaller than the radial dimension of the elastic sealing layer 1243, but larger than the radial dimension of the outer peripheral surface of the main rod portion 1242; wherein, the second connecting piece 1240 is configured as follows: when the second connecting piece 1240 is inserted into the first connecting channel 1141, the elastic sealing layer 1243 is squeezed by the inner peripheral surface of the first connecting channel 1141 to circumferentially seal the gap between the outer peripheral surface of the second connecting piece 1240 and the inner peripheral surface of the first connecting piece 1140.

[0078] It is worth understanding that the circumferential sealing of the outer circumference of the main rod 1242 and the inner circumference of the first connecting channel 1141 is achieved through a separate elastic sealing layer 1243. During the insertion process of the main rod 1242, the circumferential sealing of the main rod 1242 and the first connecting channel 1141 can be achieved, and the installation is simpler and more convenient.

[0079] In this embodiment, the first connecting piece 1140 may also be made of other materials that are not elastic and / or sealing, such as steel products. The outer peripheral surface of the second connecting piece 1240 is provided with an annular elastic sealing layer 1243, and the inner peripheral surface of the first connecting channel 1141 and the outer peripheral surface of the second connecting piece 1240 jointly extrude the elastic sealing layer 1243 to achieve sealing. The elastic sealing layer 1243 may be a coating, or an elastic sealing material adhered to the outer peripheral surface of the first connecting piece 1140 or integrally formed on the outer peripheral surface of the first connecting piece 1140, such as rubber integrally formed on the outer peripheral surface of the main rod 1242, or a sealing ring is provided on the outer peripheral surface of the main rod 1242, and the main rod 1242 may be a steel pipe.

[0080] As another embodiment, the first connecting piece 1140 may also be made of other materials that are not elastic and / or sealing, such as steel products, and an annular elastic sealing ring is provided on the inner circumference of the first connecting channel 1141, and the number of the elastic sealing rings may be one, or multiple elastic sealing rings may be distributed at intervals along the axial direction of the first connecting channel 1141. When the second connecting piece 1240 is inserted into the first connecting channel 1141, the outer circumference of the second connecting piece 1240 and the inner circumference of the first connecting channel 1141 jointly squeeze the elastic sealing ring, thereby achieving sealing between the first connecting channel 1141 and the second connecting piece 1240. The elastic sealing ring may also be replaced by an elastic coating.

[0081] Reference Figure 8 and Fig. 9 As shown, in some specific embodiments of the present invention, the first body 1100 also includes a first magnetic member 1160 arranged on the first mounting surface 1110; the second body 1200 also includes a second magnetic member 1250 arranged on the second mounting surface 1210, at least one of the first magnetic member 1160 and the second magnetic member 1250 is magnetic, and the second magnetic member 1250 can be magnetically connected to the first magnetic member 1160; the first body 1100 is provided with an annular seal 1300 on the first mounting surface 1110 and / or the second body 1200 is provided with an annular seal 1300 on the second mounting surface 1210; wherein the seal 1300 is configured as follows: when the second body 1200 is installed on the first body 1100, the seal 1300 is squeezed between the first mounting surface 1110 and the second mounting surface 1210, and surrounds and seals the connecting position.

[0082] It is worth understanding that, through the magnetic connection between the first magnetic part 1160 and the second magnetic part 1250, the seal 1300 between the first mounting surface 1110 and the second mounting surface 1210 is compressed, thereby realizing the annular seal of the seal 1300 on the connecting position, and the installation of the first body 1100 and the second body 1200 is simpler. The seal 1300 maintains a sealed state under the action of magnetic force, and the use of the seal 1300 is more reliable.

[0083] In this embodiment, the first mounting surface 1110 and / or the second mounting surface 1210 has an annular groove structure, and the seal 1300 is arranged in the annular groove structure and partially exceeds the notch position of the annular groove structure, so that the seal 1300 can be squeezed and deformed and maintain sealing. The seal 1300 is a sealing ring. Among them, the selection of the sealing ring can be based on the pressure of the slurry injection and subsequent pressurization in the microporous high-pressure resin mold. After the selection, the compression amount of the sealing ring to maintain the sealing performance is determined, and then the annular groove structure is designed so that the part of the seal 1300 extending out of the notch exceeds the compression amount of the sealing ring to ensure the sealing effect of the sealing ring.

[0084] In this embodiment, the first magnetic member 1160 and / or the second magnetic member 1250 are electromagnets, and the third magnetic member 1170 and / or the fourth magnetic member 1260 are electromagnets. Electromagnets are convenient for controlling the magnitude of their own magnetic force. When a larger magnetic force is required for locking between the first magnetic member 1160 and the second magnetic member 1250, the magnetic connection between the first magnetic member 1160 and the second magnetic member 1250 can ensure the sealing effect of the seal 1300, but the first magnetic member 1160 and the second magnetic member 1250 are difficult to separate, resulting in demolding difficulties. Therefore, the magnetic force is controlled by an electromagnet. When the microporous high-pressure resin mold is grouting, the electromagnet provides magnetic force to ensure the connection effect between the first body 1100 and the second body 1200, as well as the sealing effect of the seal 1300. When the microporous high-pressure resin mold is parted, the electromagnet reduces or cancels the magnetic force, making the separation of the first body 1100 and the second body 1200 more convenient.

[0085] Among them, the first magnetic part 1160 includes an annular electromagnet and a sealed shell, one side of the sealed shell reveals the annular magnetic attraction part of the annular electromagnet, and the gap between the sealed shell and the annular magnetic attraction part is sealed by sealant or other sealing materials. The sealed shell also leads out some wires, and the holes on the surface of the sealed shell through which the wires pass are sealed and connected to the outer peripheral surface of the wires.

[0086] As another embodiment, the first magnetic member 1160 may also be a permanent magnet. In addition, when the first magnetic member 1160 is a permanent magnet or an electromagnet, the second magnetic member 1250 may be a permanent magnet or an electromagnet, and the magnetism of the first magnetic member 1160 is opposite to that of the second magnetic member 1250, so that opposites attract each other. The second magnetic member 1250 may also be an object that does not have an active magnetic attraction but can be magnetically attracted, such as iron, so as to be directly adsorbed by the first magnetic member 1160. In addition, when the first magnetic member 1160 is iron, the second magnetic member 1250 is a permanent magnet or an electromagnet.

[0087] Reference Figure 8 and Fig. 9 As shown, in some specific embodiments of the present invention, the first magnetic component 1160 is annular and surrounds the first connecting port of the first flow channel 1120 on the first mounting surface 1110, and the second magnetic component 1250 is annular and surrounds the second connecting port of the second flow channel 1220 on the second mounting surface 1210.

[0088] It is worth understanding that the first magnetic member 1160 and the second magnetic member 1250 are both annular to apply uniform magnetic force to the annular seal 1300, so that the seal 1300 is uniformly compressed by the uniform magnetic force, so that the seal 1300 can be evenly sealed, thereby improving the sealing effect.

[0089] In this embodiment, the first magnetic member 1160 is opposite to the second magnetic member 1250, and the two are aligned with each other, the first connecting port is opposite to the second connecting port, and the two are aligned with each other to form a drainage channel sealed relative to the mold cavity. The sealing member 1300 is arranged inside the inner ring of the first magnetic member 1160 and the second magnetic member 1250. When the first magnetic member 1160 and the second magnetic member 1250 are magnetically attracted to each other, the surface of the first magnetic member 1160 and the second magnetic member 1250 contact to form a primary sealing area to restrict the mud from entering the inner ring of the first magnetic member 1160 and the second magnetic member 1250. Then the sealing member 1300 seals the gap between the first magnetic member 1160 and the second magnetic member 1250. The sealing member 1300 forms a secondary sealing area to completely restrict the mud from entering the first flow channel 1120 and the second flow channel 1220.

[0090] Reference Figure 8 and Fig. 9As shown, in some specific embodiments of the present invention, the first main body 1100 also includes a third magnetic component 1170 disposed on the first mounting surface 1110, the first magnetic component 1160 and the third magnetic component 1170 are both magnetic and both are annular, the first magnetic component 1160 and the third magnetic component 1170 have opposite magnetism, and the third magnetic component 1170 is sleeved outside the first magnetic component 1160 and is adjacent to the first magnetic component 1160; the second main body 1200 also includes a fourth magnetic component 1260 disposed on the second mounting surface 1210, the second magnetic component 1250 and the fourth magnetic component 1260 are both magnetic and both are annular, the second magnetic component 1250 and the fourth magnetic component 1260 have opposite magnetism, and the fourth magnetic component 1260 is sleeved outside the second magnetic component 1250 and is adjacent to the second magnetic component 1250.

[0091] It is worth understanding that, by means of a separate third magnetic component 1170 and a fourth magnetic component 1260, the relative positions of the first magnetic component 1160 and the second magnetic component 1250, and the relative positions of the first flow channel 1120 and the second flow channel 1220 are positioned. After the first body 1100 and the second body 1200 are installed, the first connecting port formed by the first flow channel 1120 on the first mounting surface 1110 will automatically align with the second connecting port formed by the second flow channel 1220 on the second mounting surface 1210, thereby achieving alignment and connection between the first connecting port and the second connecting port, and facilitating timely discharge of moisture.

[0092] Specifically, when the first magnetic component 1160 and the second magnetic component 1250 are partially misaligned, the first magnetic component 1160 will be opposite to the fourth magnetic component 1260, and the magnetism of the first magnetic component 1160 is the same as that of the fourth magnetic component 1260, so that the first body 1100 is subjected to repulsive force and cannot be installed. At the same time, the second magnetic component 1250 will attract the first magnetic component 1160 to move toward a completely overlapping position, so that the second magnetic component 1250 can completely overlap with the first magnetic component 1160, and at the same time, the third magnetic component 1170 also completely overlaps with the fourth magnetic component 1260, and the first connecting port is aligned with the second connecting port.

[0093] The first communication port may be disposed at the annular center of the first magnetic member 1160 , and the second communication port may be disposed at the annular center of the second magnetic member 1250 . Furthermore, the annular center of the sealing member 1300 coincides with the annular center of the first magnetic member 1160 or the annular center of the second magnetic member 1250 .

[0094] In some specific embodiments of the present invention, the first body 1100 further includes a first guide portion disposed on the first mounting surface 1110, and the second body 1200 further includes a second guide portion disposed on the second mounting surface 1210, and the second guide portion cooperates with the first guide portion.

[0095] It is worth understanding that the first body 1100 and the second body 1200 can also be guided by separate first guide parts and second guide parts, so that the first magnetic member 1160 and the second magnetic member 1250 can be relatively aligned, and the first connecting port can be aligned with the second connecting port.

[0096] In this embodiment, the first guide portion is a guide rod, and the second guide portion is a guide slot. The guide rod is inserted into the guide slot to achieve alignment and installation of the first body 1100 and the second body 1200.

[0097] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
