Abstract

The present invention discloses a molding method and mold for a waist-tightening toilet, and the waist-tightening toilet. The molding method molds the outer shell, seat ring, pipe, and bladder bag of the waist-tightening toilet separately and then bonds them together. The outer shell includes an upper wall located above the waistline and a lower wall located below the waistline. The lower wall has an inner wall and an outer wall distributed inside and outside. There is a cavity between the inner wall and the outer wall, so that the lower wall forms a hollow wall that can support the upper wall. The present invention makes the thickness of the lower wall of the molded outer shell larger and the strength better. The outer shell is not easily deformed or cracked after molding, so that the waist-tightening toilet can be molded using an inner-outer-outer process and is suitable for high-pressure molding.

Description

Technical Field

[0001] The present invention relates to a bathroom product, in particular to a molding method and a mold for a waist-tightening toilet and the waist-tightening toilet. Background Art

[0002] At present, the production methods of toilets can be roughly divided into the following three types:

[0003] 1. Conventional toilet development and production involves splitting the mold and removing the blanks in small pieces. The mold primarily consists of the main body, left and right molds, base, small side mold pieces (left and right), small pipe pieces (left and right), gallbladder tip, small gallbladder bag pieces (4-5 pieces), small water tank pieces (4 pieces), and a pallet. During operation, after grouting is completed and sufficient time has passed for consolidation, the mold opening sequence is: ① Open the bottom mold; ② Open the side mold; ③ Demold the small side mold pieces; ④ Demold the small pipe pieces; ⑤ Use the pallet and blank turning vehicle to remove the blanks from the main body; ⑥ Demold the gallbladder and water tank molds. Toilets produced in this way have an integrated outer shell, gallbladder, pipes, seat, and water tank, without separate bonding. This results in good integrity, but the presence of numerous small production mold pieces, such as small pipe pieces, side mold pieces, water tank pieces, and gallbladder bag pieces, makes them unsuitable for high-pressure molding.

[0004] 2. Develop and produce using conventional bonding methods, with mold separation and blanking performed in the form of disassembling small parts. The molds mainly include the main body mold, water tank mold, and seat ring mold. The main body mold is divided into medium-sized body, left-side mold, right-side mold, bottom mold, left-side small parts, right-side small parts, left pipe small parts, right pipe small parts, medium-sized body small parts, and main body support plate. The demolding order is: bottom mold, medium-sized, and then relying on the main body support plate, demold the left and right side molds, and finally demold the side molds and pipe small parts. This method separately forms the three modules of the toilet body, water tank, and seat ring, and then these three modules are bonded. The main body includes pipes, a bladder bag, an outer shell, and bottom molding. The main body has strong self-stabilization ability, and the double-sided slurry structure is mainly used below the waistline. However, small pipe parts and side mold small parts need to be demolded from the main body mold, which is not conducive to high-pressure molding.

[0005] 3. Conventional inner and outer shell molding process, with the outer shell, liner and pipe, seat ring, and water tank four components are molded separately and finally bonded together. This inner and outer shell mode is the simplest and most effective, and is conducive to the realization of mechanized and digital control molding. However, the appearance of the toilet produced by this inner and outer shell molding process is limited, specifically limited to the shape with a smooth transition, smooth and uniform force on the outer surface (such as a large bag appearance toilet). If the slope of the curved surface of the toilet changes suddenly at a certain position, such as a "waist-type toilet", it is not suitable for this inner and outer shell molding process. This is because in the existing inner and outer shell molding technology, the outer shell part of the toilet needs to be molded independently, and there is a large area of ​​double-sided pulp blank distributed longitudinally around it. Because the outer shell needs to be bonded with other modules, a space needs to be left in the middle. From a mechanical point of view, the outer shell blank has no supporting structure after demolding. Since the blank around the outer shell is thin and has weak self-stabilization ability, it is easy to deform. For toilets with smooth, flowing curves (such as those with a large, rounded design), the outer shell exhibits no stress concentration, and force is evenly transferred from top to bottom, making them suitable for molding using conventional inner-outer-outer processes. However, for toilets with a narrow waist, the outer shell suddenly turns outward from bottom to top at the waistline, causing a change in force. This causes the upper wall of the outer shell to exert a greater force on the lower wall, making the outer shell easily deformed or cracked. Therefore, conventional inner-outer-outer-outer processes are not suitable for these toilets with a narrow waist. Summary of the Invention

[0006] In response to the technical problems existing in the prior art, the present invention provides a molding method and mold for a waist-tightening toilet, and a waist-tightening toilet, which enables the waist-tightening toilet to be molded using an inner-outer-outer process and can prevent the outer shell of the waist-tightening toilet from deforming or cracking.

DETAILED DESCRIPTION

[0041] In the present invention, the terms "first", "second", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. In the description, the directions or positional relationships indicated by "upper", "lower", "left", "right", "front", and "back" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and are not intended to indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0042] See Figures 1-12 As shown, the present invention is a method for forming a waist-type toilet, wherein the outer shell, seat ring, pipe and bladder bag of the waist-type toilet are formed separately and then bonded together, and the outer shell includes an upper wall body located above the waist line and a lower wall body located below the waist line, and the lower wall body has an inner wall body and an outer wall body distributed inside and outside, and a cavity is formed between the inner wall body and the outer wall body, so that the lower wall body forms a hollow wall body that can support the upper wall body. The structure of the outer shell 1 is as shown Figure 1-Figure 7 As shown, the jacket 1 is hollow inside, with openings at the upper and lower ends, and the upper opening is larger than the lower opening. The jacket 1 includes an upper wall 11 and a lower wall 12 distributed vertically, and the upper wall 11 and the lower wall 12 are separated by a waistline. After the lower wall 12 includes the inner wall 121 and the outer wall 122, the thickness of the lower wall 12 (the sum of the thickness of the inner wall 121, the thickness of the outer wall 122, and the thickness of the cavity 123 between the inner wall 121 and the outer wall 122) is increased and is greater than the thickness of the upper wall 11. Therefore, the strength of the lower wall 12 is significantly improved, and it can effectively support the upper wall 11, avoiding deformation or cracking of the jacket 1 after molding.

[0043] In this embodiment, the outer shell 1 is formed by an outer shell mold, and the steps of producing the outer shell of the waist-type toilet with the outer shell mold 2 include: closing the outer shell mold 2, grouting, and opening the mold in sequence, wherein, when closing the mold, the mold spacing of the outer shell mold 2 above the outer shell waist line is 10 to 20 mm, so as to achieve two-sided grouting to form the upper wall 11, and the mold spacing of the outer shell mold 2 below the outer shell waist line is greater than 30 mm, so as to achieve single-sided grouting to form the lower wall 12. Figure 8 As shown, the outer mold 2 specifically includes a side mold assembly (the side mold assembly specifically includes, but is not limited to, a first left mold 21 and a first right mold 22), a first top mold 23, and a first bottom mold 24. When the mold is closed, the side mold assembly (i.e., the first left mold 21 and the first right mold 22 correspond to each other on the left and right) surround a mold cavity that runs vertically through. The first top mold 23 and the first bottom mold 24 each partially enter the mold cavity and dock vertically. Therefore, when the outer mold 2 is closed, the spacing between the first top mold 23 and the side mold assembly (i.e., the first left mold 21 and the first right mold 22) is controlled to be 10-14 mm, and the spacing between the first bottom mold 24 and the side mold assembly (i.e., the first left mold 21 and the first right mold 22) is controlled to be greater than 30 mm.

[0044] In this embodiment, the side of the inner wall 121 facing away from the outer wall 122 is provided with a plurality of reinforcing ribs 124 distributed along its circumference, with each reinforcing rib 124 being located in the upper and lower directions. This further enhances the strength of the lower wall 12 of the outer jacket 1, thereby further increasing the support force of the lower wall 12 on the upper wall 11, making the outer jacket 1 less susceptible to deformation or cracking.

[0045] In this embodiment, the present invention also forms the water tank of the waist-type toilet independently and bonds it with the outer shell, seat ring, pipe and bladder bag. Specifically, the present invention uses a seat ring mold to form the seat ring, a pipe and bladder bag mold to form the pipe and bladder bag, and a water tank mold to form the water tank. Figure 9 As shown, the seat ring mold 3 includes a seat ring top mold 31 and a seat ring bottom mold 32, and the seat ring top mold 31 and the seat ring bottom mold 32 correspond to each other up and down. Figure 10 As shown, the pipe and bile bag mold 4 includes a second left mold 41, a second right mold 42, a second top mold 43 and a second bottom mold 44. The second left mold 41 and the second right mold 42 are matched left and right, and the second top mold 43 and the second bottom mold 44 are matched up and down. When the mold is closed, they enter the mold cavity surrounded by the second left mold 41 and the second right mold 42. Figure 11 As shown, the water tank mold 5 includes a water tank top mold 51 and a water tank bottom mold 52. The water tank top mold 51 and the water tank bottom mold 52 correspond to each other up and down, and when the mold is closed, the water tank top mold 51 partially enters the water tank bottom mold 52.

[0046] In this embodiment, the steps of bonding the water tank, outer shell, seat ring, pipe and bladder bag together include:

[0047] Applying mud on the bonding surface of the formed seat ring (in the green state), bonding and fixing the seat ring with the formed pipe and the bladder bag (in the green state) to obtain a first green body;

[0048] Applying slurry on the bonding surface of the first blank and inserting it into the formed outer shell (in the blank state), bonding and fixing the first blank and the outer shell to obtain a second blank;

[0049] Slurry is applied to the bonding surface of the second blank, and the second blank is bonded and fixed to the water tank (in blank state) to obtain a toilet blank.

[0050] The detailed process flow of the molding method of the waist-tightening toilet of the present invention is as follows:

[0051] The first left mold 21, the first right mold 22, the first top mold 23 and the first bottom mold 24 of the jacket mold 2 are respectively fixed on the high-pressure equipment (the first top mold 23 is at the bottom and the first bottom mold 24 is at the top), and the overall mold is first closed, and then grouting is performed. After the jacket blank has been solidified for a sufficient time, the first top mold 23 and the first bottom mold 24 are demolded, and the jacket blank (the jacket blank is in an inverted state) remains in the first left mold 21 and the first right mold 22 for standby use;

[0052] The seat ring top mold 31 and the seat ring bottom mold 32 of the seat ring mold 3 are fixed on the high-pressure equipment respectively, and the mold is closed, grouting is performed, and after consolidation is completed, the seat ring bottom mold 32 is opened first and the first supporting plate is placed on it, and then the seat ring blank (the seat ring blank is in an inverted state) is separated from the seat ring top mold 31 and placed on the first supporting plate for standby use;

[0053] The second left mold 41, the second right mold 42, the second top mold 43 and the second bottom mold 44 of the pipe and bladder package mold 4 are fixed on the high-pressure equipment respectively. After the mold closing, grouting and consolidation are completed, the second bottom mold 44 is opened, and the seat ring blank placed on the support plate is moved to the bottom of the pipe and bladder package mold 4. Mud is applied on the bonding surface of the seat ring blank by a machine, and then the first support plate is moved upward to bond the seat ring blank to the pipe and bladder package blank (the pipe and bladder package blank is in an inverted state) to obtain the first blank; then, the second top mold 43, the second left mold 41 and the second right mold 42 are opened, and the first blank obtained after bonding is placed on the first support plate for standby use;

[0054] The first blank is moved to the bottom of the outer shell blank by a first support plate, and the bonding surface of the first blank is first coated with slurry by a machine. Then the first blank is raised (or the outer shell mold 2 is controlled to lower with the outer shell), so that the first blank and the outer shell blank are bonded and fixed to obtain the second blank;

[0055] The second blank, the first support plate, the first left mold 21, and the first right mold 22 are turned 180 degrees as a whole and placed on the second support plate for standby use;

[0056] The water tank top mold 51 and the water tank bottom mold 52 of the water tank mold 5 are fixed on the high-pressure equipment respectively, and after mold closing, grouting, consolidation and mold opening, the water tank blank is placed on the third pallet for standby use;

[0057] The second body is slurried and bonded to the water tank body to form a complete toilet body.

[0058] The toilet body is dried, glazed and fired in sequence to obtain a finished product of a waist-shaped toilet. Figure 12 shown.

[0059] The present invention provides a molding method for a waist-tightening toilet. Since the lower wall 12 of the outer shell 1 produced by the outer shell 1 located below its waistline has an inner wall 121 and an outer wall 122 distributed inside and outside, and there is a cavity between the inner wall 121 and the outer wall 122, the lower wall 12 forms a hollow wall that can support the upper wall 11 of the outer shell. Therefore, the outer shell is not easy to deform or crack after molding, so that the waist-tightening toilet can be molded using the inner and outer shell process and is suitable for high-pressure molding.

[0060] See Figures 1-12 As shown, a forming mold for a waist-tightening toilet of the present invention includes a coat mold 2 for producing the coat of the waist-tightening toilet, and the coat mold 2 includes a side mold assembly, a first top mold 23 and a first bottom mold 24. When the mold is closed, the side mold assembly forms a mold cavity that passes through from top to bottom, and the first top mold 23 and the first bottom mold 24 partially enter the mold cavity respectively and dock with each other up and down, and the first top mold 23 cooperates with the side mold assembly to form an upper wall 11 of the coat 1 above its waist line, and the first bottom mold 24 cooperates with the side mold assembly to form a lower wall 12 of the coat 1 below its waist line, and the lower wall 12 has an inner wall 121 and an outer wall 122 distributed inside and outside, and there is a cavity 123 between the inner wall 121 and the outer wall 122, so that the lower wall 12 forms a hollow wall that can support the upper wall 11.

[0061] In this embodiment, the side mold assembly specifically includes a first left mold 21 and a first right mold 22, but is not limited thereto. The first left mold 21 and the first right mold 22 are matched with each other on the left and right sides.

[0062] In this embodiment, when the outer mold 2 is closed, the distance between the first top mold 23 and the side mold assembly (i.e., the first left mold 21 and the first right mold 22) is 10 to 20 mm, so as to achieve two-sided slurry suction to form the upper wall 11, and the distance between the first bottom mold 24 and the side mold assembly (i.e., the first left mold 21 and the first right mold 22) is greater than 30 mm, so as to achieve single-sided slurry suction to form the lower wall 12.

[0063] In this embodiment, the outer surface of the first bottom mold 24 is provided with a plurality of strip-shaped grooves 2421 distributed along its circumference, each of which is located in the vertical direction. This allows the side of the inner wall facing away from the outer wall to have a plurality of reinforcing ribs 124 distributed along its circumference, with each of the reinforcing ribs 124 located in the vertical direction. This further enhances the strength of the lower wall 12 of the outer shell 1, thereby further increasing the support force of the lower wall 12 of the outer shell on the upper wall 11, making the outer shell 1 less susceptible to deformation or cracking.

[0064] In this embodiment, the first top mold 23 specifically includes a top plate 231 and an upper mold body 232 disposed at the bottom end of the top plate 231. The first bottom mold 24 specifically includes a bottom plate 241 and a lower mold body 242 disposed at the top end of the bottom plate 241. The strip-shaped groove 2421 is provided on the outer circumferential surface of the lower mold body 242. When the molds are closed, the first left mold 21 and the first right mold 22 are combined to form a vertically continuous wall, with the upper end of the wall resting on the bottom surface of the top plate 231 and the lower end of the wall resting on the top surface of the bottom plate 241. The upper mold body 232 and the lower mold body 242 are butted against each other.

[0065] In this embodiment, the present invention also includes a seat ring mold 3 for producing the seat ring of the waist-type toilet, a pipe and liner mold 4 for producing the pipe and liner of the waist-type toilet, and a water tank mold 5 for producing the water tank of the waist-type toilet.

[0066] In this embodiment, Figure 9 As shown, the seat ring mold 3 includes a seat ring top mold 31 and a seat ring bottom mold 32, and the seat ring top mold 31 and the seat ring bottom mold 32 correspond to each other up and down. Figure 10 As shown, the pipe and bile bag mold 4 includes a second left mold 41, a second right mold 42, a second top mold 43 and a second bottom mold 44. The second left mold 41 and the second right mold 42 are matched left and right, and the second top mold 43 and the second bottom mold 44 are matched up and down. When the mold is closed, they enter the mold cavity surrounded by the second left mold 41 and the second right mold 42. Figure 11 As shown, the water tank mold 5 includes a water tank top mold 51 and a water tank bottom mold 52. The water tank top mold 51 and the water tank bottom mold 52 correspond to each other up and down, and when the mold is closed, the water tank top mold 51 partially enters the water tank bottom mold 52.

[0067] The working principle of the molding die of the waist-type toilet of the present invention is as follows: the outer shell mold 2 is used to produce the outer shell of the waist-type toilet to obtain the outer shell blank, the seat ring mold 3 is used to produce the seat ring of the waist-type toilet to obtain the seat ring blank, the pipe and bladder bag mold 4 is used to produce the pipe and bladder bag of the waist-type toilet to obtain the pipe and bladder bag blank, the water tank mold 5 is used to produce the water tank of the waist-type toilet to obtain the water tank blank, the outer shell blank, the seat ring blank, the pipe and bladder bag blank, and the water tank blank are bonded together to obtain a complete toilet blank, and the toilet blank is sequentially dried, glazed, and fired normally to obtain a finished product of the waist-type toilet. Figure 12 The detailed working process of the molding die of the waist-tightening toilet of the present invention can be referred to the detailed process flow of the molding method of the waist-tightening toilet of the present invention, which will not be repeated here.

[0068] The molding mold of a waist-tightening toilet of the present invention has a double-layer wall body 12 of the outer shell 1 produced by its outer shell mold 2, forming a hollow wall body, so that the thickness of the lower wall body 12 is increased and is greater than the thickness of the upper wall body 11, so that the strength of the lower wall body 12 is significantly improved, and it can effectively support the upper wall body 11. Therefore, the outer shell is not easy to deform or crack after molding, so that the waist-tightening toilet can be molded using the inner and outer shell process and is suitable for high-pressure equipment.

[0069] See Figure 11-13 As shown, a waist-type toilet of the present invention includes a cover 1 with a waist line, and the cover 1 includes an upper wall 11 located above the waist line and a lower wall 12 located below the waist line. The lower wall 12 has an inner wall 121 and an outer wall 122 distributed inside and outside, and a cavity 123 is formed between the inner wall 121 and the outer wall 122, so that the lower wall 12 forms a hollow wall that can support the upper wall 11.

[0070] In this embodiment, the side of the inner wall 121 facing away from the outer wall 122 is provided with a plurality of reinforcing ribs 124 distributed along its circumference, with each reinforcing rib 124 being located in the upper and lower directions.
