The high pressure grouting toilet bowl is one of the production methods of the toilet bowl, and is characterized in that slurry is injected into a mold, the surface of the inner cavity of the mold is made of permeable materials, water in the inner cavity of the mold is discharged by high pressure, and redundant slurry is discharged after a blank body is shaped to form the blank body with a certain wall thickness.

In high-pressure grouting molding of a toilet, the toilet is generally divided into three parts, namely a seat ring, an inner container and the periphery, which are respectively grouting molded and then bonded together, wherein the inner container is used for forming a urinal of the toilet, a trap communicated with the urinal through a sewage inlet, a siphon communicated with the trap through a sewage outlet and the like. After the inner container blank is formed, an injection port communicated with the trap is formed on the opposite side of the drain by manpower, and the injection port is aligned with the drain and used for flushing water to form a siphon effect in the siphon pipe so as to drain.

Because the jet is arranged at the opposite side of the sewage outlet, the user can easily see the water when using the toilet, and the appearance is bad. For this reason, in the prior art, after the molding of the toilet liner blank, a shutter small member which is additionally molded is manually adhered to the side of the trap close to the injection port and above the injection port, thereby shielding the injection port. However, since the shielding plate is manually bonded, cracking is extremely likely to occur during drying and firing of the inner liner, and the yield is low.

The second technical scheme is based on the first technical scheme, wherein when the toilet liner blank is molded by grouting, the top of the lower die is not lower than the bulge in the longitudinal direction of the side die.

The third technical scheme is based on the second technical scheme, wherein when the toilet liner blank is molded by grouting, the distance between the bulge and the top of the lower die is larger than the wall thickness of the toilet pool wall of the toilet liner blank after grouting in the horizontal direction.

The fourth technical scheme is based on the first technical scheme, wherein the top of the lower die is provided with a slurry suction prevention part.

The fifth technical scheme is based on the fourth technical scheme, wherein the upper surface of the slurry suction prevention part is an inclined surface, and when the toilet liner blank is molded by grouting, one side of the inclined surface, which is far away from the toilet drain, is lower than one side, which is close to the toilet drain, in the longitudinal direction of the side mold.

A sixth technical means is based on the fourth technical means, wherein the anti-suction portion is formed of a nylon block.

A seventh technical aspect relates to a method for manufacturing a toilet bowl liner blank, wherein the toilet bowl liner blank is formed by reverse slip casting using the high pressure toilet bowl liner blank mold according to any one of claims 1 to 6, the method comprising a mold closing stage, a slip casting stage, a surplus slurry discharging stage, and a mold releasing stage, wherein an included angle between the lower mold and a horizontal plane is 13 degrees to 17 degrees in the surplus slurry discharging stage.

An eighth technical means is based on the seventh technical means, wherein the mold closing stage is to close the two side molds after draining the two side molds and the upper and lower molds, then close the upper and lower molds to form a mold assembly, and then press the mold assembly in a left-right, front-rear direction; the grouting stage is to incline the whole mould at 13-17 degrees, open the grouting valve to grouting, the grouting pressure is 0.1-0.2MPa, the time is 150-200 seconds, so that the slurry is rapidly filled in the mould space, then the grouting pressure is changed to 1-1.05MPa, the time is 450-600 seconds, so that the slurry is rapidly molded on the surface of the mould; and the stage of discharging the redundant slurry is to open the micro-pressure pipe and the grouting valve simultaneously, and the micro-pressure pipe is filled with compressed air with the pressure of 0.1-0.15MPa for discharging the slurry for 60-90 seconds, and the grouting valve is closed after the end.

The ninth technical scheme is based on the seventh technical scheme, wherein after the toilet liner blank is demolded, the opposite side of the sewage outlet is provided with the jet orifice.

A tenth technical means relates to a toilet bowl, wherein the liner blank manufactured by the manufacturing method of the toilet bowl liner blank according to any one of the claims 7 to 9 is used.

From the above description of the present invention, compared with the prior art, the present invention has the following advantages:

through set up the arch that is used for shaping shielding plate on the side mould, bellied position is corresponding with the position of shielding plate for shielding plate can integrated into one piece in the closestool inner bag body and need not to bond shielding plate smalls in addition when slip casting closestool inner bag body, thereby can reduce shielding plate dry, the probability of cracking during the sintering. And just because when the toilet liner blank is formed by back-off slip casting, the top of the lower die does not cross the bulge in the longitudinal direction of the side die so as to provide abdication for the bulge, the bulge for forming the shielding plate can be arranged on the side die on the premise of not changing the space of the water trap.

When the toilet liner blank is formed by grouting, the top of the lower die is not lower than the bulge in the longitudinal direction of the side die, so that the problem that dirt is difficult to remove due to the fact that the height of a water trap is too high after grouting is avoided.

Because the bulge is arranged on the side die, the shielding plate is integrally formed on the liner blank instead of being adhered to the liner blank, and the situation of concave at the shielding plate can occur, so that the problem of the supporting strength of the closestool after grouting molding is also required to be considered. Therefore, when the blank of the toilet liner is molded by grouting, the distance between the protrusion and the top of the lower die in the horizontal direction is larger than the wall thickness of the toilet tank wall of the toilet liner after grouting, so that the wall thickness at the shielding plate is larger, and the supporting strength is ensured.

By arranging the anti-sucking part at the top of the lower die, the toilet bowl with the sewage inlet command can be directly formed to communicate with the water trap without manual opening after the toilet liner blank is molded by grouting. The anti-suction portion may be formed of a nylon block.

Through making the upper surface of preventing inhaling thick liquid portion be the inclined plane to when slip casting closestool inner bag body, the inclined plane is kept away from one side of closestool drain in the longitudinal direction of side mould and is less than one side that is close to the closestool drain, consequently can avoid the drain opening too big, thereby avoid influencing the circumstances that the spout spun water is difficult to be full of the siphon fast and then is difficult to form siphon effect in the siphon when washing by water.

When the high-pressure toilet liner blank mold provided by the invention is used for molding a toilet liner blank in a back-off grouting mode, the included angle between the lower mold and the horizontal plane at the stage of discharging the redundant slurry is 13-17 degrees, so that the redundant slurry at the water storage bend can be discharged.

The positions of the bowl wall 4, the trapway 5 and the shield 3 of the toilet are shown in figure 1.

The mold for molding the liner blank in the high-pressure grouting molding closestool generally at least comprises side molds 2 positioned at the left side and the right side and a lower mold 1 positioned below. As shown in fig. 1, the applicant researches have found that, in the prior art, it is necessary to additionally adhere the shielding plate 3, and the reason why the shielding plate 3 cannot be directly integrally formed when the toilet liner blank is injection molded is that the conventional method adopts a double-sided slurry feeding mode at the water trap 5 of the toilet. That is, the highest portion of the lower mold is protruded into the trap 5 and is adjacent to the side molds 2 on both sides, so if the protrusions 9 for forming the shielding plate 3 are provided on the side molds 2, the protrusions 9 may be abutted against the lower mold 1, and even if not abutted against the lower mold 1, the space between the protrusions and the lower mold 1 may be too close, which may result in too thin a toilet liner blank after slip casting and easy collapse. If the lower mold 1 is recessed to give way to the projections 9 forming the shielding plate 3, the lower mold 1 cannot be released after the slip casting.

The high-pressure toilet liner blank mold provided by the embodiment can avoid the problems, and the protrusion 9 for forming the shielding plate 3 can be directly formed on the side mold 2, so that the shielding plate 3 and the toilet liner are integrally formed without additional adhesion, the cracking probability of the shielding plate 3 during the drying and sintering processes is reduced, and the yield is improved.

As shown in fig. 3 and 4, the high-pressure toilet liner blank mold provided in this embodiment is suitable for forming a toilet liner blank by means of back-off grouting, and is the same as the prior art, and includes two side molds 2 and a lower mold 1. Wherein the side mould 2 is provided with a bulge 9 for shaping the shielding plate 3; the top of the lower die 1 is provided with a slurry suction prevention part 8, and the slurry suction prevention part 8 means that slurry cannot be adsorbed on the slurry in the grouting process, so that a sewage inlet command toilet bowl communicated with the trap 5 can be directly formed after a toilet liner blank is molded by grouting without manual opening. In this embodiment, the anti-suction portion 8 is formed of a nylon block, which has a substantially plate shape, and has an inclined surface on its upper surface, and a vertical distance between the lowest point and the highest point of the inclined surface is 5 to 8 mm.

When the toilet bowl liner blank is molded by grouting, the top of the lower die 1, namely the anti-sucking part 8, does not cross the bulge 9 of the side die 2 in the longitudinal direction of the side die, so that yielding can be provided for the bulge 9, and therefore, yielding can be provided for the bulge 9, and the bulge 9 for molding the shielding plate 3 can be arranged on the side die 2 on the premise of not changing the space of the trap 5 or increasing the wall thickness of the trap 5; the anti-suction part 8 is not lower than the position of the bulge 9 on the side die 2, so that the phenomenon that dirt is difficult to remove due to the excessively high height of the trap 5 after grouting molding is avoided; and the side of the upper surface of the anti-sucking part 8, which is far away from the toilet drain 7, is lower than the side, which is close to the toilet drain 7, so that the oversized opening of the drain 7 can be avoided, and the situation that water sprayed from a water spray port is difficult to quickly fill the siphon 6 and then difficult to form a siphon effect in the siphon 6 during flushing is avoided. In the horizontal direction, the distance between the bulge 9 and the anti-sucking part 8 is larger than the wall thickness of the urinal wall 4 of the blank body of the toilet liner after grouting molding, so that the wall thickness at the shielding plate 3 is larger, and the supporting strength is ensured. In this embodiment, the distance between the protrusion 9 and the anti-sucking portion 8 is 15 mm, and the wall thickness of the bowl wall 4 of the toilet liner blank is 12 to 13 mm.

It should be noted that, the toilet liner blank manufactured by using the high-pressure toilet liner blank mold provided in this embodiment, in which the shielding plate 3 is integrally formed, has the position of the shielding plate 3 substantially the same as that of the shielding plate 3 bonded by manual bonding in the prior art, so that it is easy for a person skilled in the art to determine the installation position of the protrusion 9. Therefore, the pain point in the prior art is not to determine the position of the protrusion 9, but to prevent the protrusion 9 from colliding with the lower mold 1, so that the protrusion 9 can be arranged on the side mold 2, and to ensure the overall supporting strength after integrally forming the shielding plate 3 on the toilet liner blank.

In addition, as shown in fig. 2, as described above, the prior art trap 5 is formed by double-sided suction, so that in the stage of discharging the surplus slurry, the surplus slurry is not required to be discharged at the trap 5, and the surplus slurry in the siphon 6 can be discharged only by 8-10 degrees of the included angle 10 between the lower die 1 and the horizontal plane.

However, in the toilet liner blank mold provided in this embodiment, the top of the lower mold 1 does not cross the protrusion 9 of the side mold 2, so that the top of the lower mold does not enter the trapway 5 of the toilet, so compared with the prior art, the molding mode of the toilet liner blank mold trapway 5 provided in this embodiment is changed to single-sided slurry suction, which results in the need of discharging the surplus slurry at the trapway 5, and the included angle 10 of 8-10 degrees cannot meet the requirement of discharging the slurry at the trapway 5. However, the forming mode of the trap 5 is changed into a single-sided slurry suction mode, so that the sewage outlet 7 can be integrally formed without manual opening.

Therefore, the embodiment also provides a manufacturing method of the toilet bowl liner blank, which adopts the high-pressure toilet bowl liner blank mold in the embodiment to mold the toilet bowl liner blank in a back-off grouting mode. It comprises the following steps:

in the mold closing stage, after the two side molds 2 and the upper and lower molds are drained, the two side molds 2 are closed, the upper mold and the lower mold are closed, so that the whole mold is formed, and then the whole mold is pressurized left and right and front and back to fix the whole mold.

And in the grouting stage, the whole mould is inclined by 13-17 degrees, a grouting valve is opened for grouting, the grouting pressure is 0.1-0.2MPa, the grouting time is 150-200 seconds, so that the mould space is quickly filled with slurry, then the grouting pressure is changed to 1-1.05MPa, and the grouting time is 450-600 seconds, so that the slurry is quickly formed on the surface of the mould.

And in the stage of discharging the redundant slurry, simultaneously opening a micro-pressure pipe and a grouting valve, introducing compressed air with the pressure of 0.1-0.15MPa into the micro-pressure pipe to discharge the slurry for 60-90 seconds, and closing the grouting valve after the end.

And (3) a demolding stage. As shown in fig. 7-8, after the toilet liner blank is demolded, the jet orifice 11 is opened on the opposite side of the sewage outlet 7 by a person.

In the stage of discharging the surplus slurry, the angle 10 between the lower die 1 and the horizontal plane is 13 to 17 degrees as shown in fig. 5, so that the surplus slurry at the trap 5 is discharged.

In addition, the embodiment also provides a toilet bowl, which adopts the inner container blank manufactured by the manufacturing method of the toilet bowl inner container blank provided in the embodiment.

The foregoing description of the embodiments and description is presented to illustrate the scope of the invention, but is not to be construed as limiting the scope of the invention. Modifications, equivalents, and other improvements to the embodiments of the invention or portions of the features disclosed herein, as may occur to persons skilled in the art upon use of the invention or the teachings of the embodiments, are intended to be included within the scope of the invention, as may be desired by persons skilled in the art from a logical analysis, reasoning, or limited testing, in combination with the common general knowledge and/or knowledge of the prior art.
