Description
Technical Field
The invention relates to the field of bathroom, in particular to a high-strength closestool and a forming device thereof.
Background
In the prior art, toilet molding can be classified into normal pressure molding and high pressure molding. Wherein, the normal pressure molding is to adopt a gypsum mold for normal pressure grouting, and the toilet is obtained by one-step molding without the bonding procedure. However, the normal pressure molding requires a large number of small mold pieces, and the molding process requires mold filling and demolding, and has long operation time and low efficiency.
The high-pressure molding is to use a resin mold to perform slip casting by high pressure, so that the production efficiency is high, and the high-pressure molding becomes a mainstream technology gradually. However, since the grouting pressure is high, dislocation occurs if a large number of small mold pieces are used, and molding defects are caused, so that the small mold pieces need to be used as few as possible.
On the other hand, because the closestool structure is comparatively complicated, in order to realize high pressure slip casting, the closestool needs to be subjected to block design, slip casting respectively and then bonding. The size of the segments determines the complexity of the bonding process and the complexity of the mold. The curing thinking of those skilled in the art is to minimize the number of bonding times to reduce bonding time and defects caused by bonding.
In addition, for the closestool bent pipe, the existing forming technology adopts single-sided slurry forming, specifically means that in the forming process, only the outer wall of a pipeline contacts with a die, the inner wall of the pipeline is not attached to the die, slurry is adsorbed on the pipeline die by means of pressure after being injected into the pipeline die, a cavity is naturally formed in the pipeline, and after the die is opened, the outer wall of the pipeline contacts with air and is hardened to form a bent pipe blank. However, this single-sided slurry molding method has the following drawbacks: 1, the thickness of the pipeline is determined according to the injection, consolidation and discharge time of slurry, and the exact wall thickness of the pipeline cannot be standardized; 2, after the die is opened, the outer wall of the pipeline is contacted with air to start hardening, the air contacted with the inner part is less, the convection is less, the hardening speed is low, and the hardening degree is inconsistent; and 3, as the pipeline plays a supporting role in the structure of the closestool, the pipeline needs to bear larger weight, the poor strength of the bent pipe can lead to insufficient support of the closestool blank in the later natural hardening process, the defects of deformation and cracking are easy to generate, and the rate of finished products of the closestool is reduced.
Because the normal pressure molding is one-step molding, the bent pipe can only be molded by single-sided slurry. In the case of high-pressure molding, in some cases, the bent pipe and other components are integrally molded, and only single-sided slurry molding can be adopted; in other cases, even if the bent pipe is formed independently, the problems of bonding difficulty and production efficiency are considered; one skilled in the art would also have an inherent thinking of using single facer slurry to form the elbow.

It is only stated that the terms of orientation such as up, down, left, right, front, back, inner, outer, etc. used in this document or the imminent present invention, are used only with reference to the drawings of the present invention, and are not meant to be limiting in any way.
Referring to fig. 1; the embodiment provides a high-strength closestool, which comprises a bent pipe 1, a urinal body 2 and a skirt 3; wherein, the urinal body 2 and the skirt 3 are of an independent integrated structure; the elbow 1 comprises a first half pipe 11 and a second half pipe 12, and the first half pipe 11 and the second half pipe 12 are bonded to form the elbow 1. Wherein the first half pipe 11 and the second half pipe 12 are of a double-sided slurry structure.
Specifically, referring to fig. 2 and 3, in the present embodiment, the first half pipe 11 is provided with a positioning groove 111, the second half pipe 12 is provided with a positioning flange 121, and the positioning groove 111 is matched with the positioning flange 121, so that the first half pipe 11 and the second half pipe 12 can be quickly positioned, and the bonding accuracy is improved.
The second half pipe 12 is also provided with a rib plate 13, and two sides of the rib plate 13 are provided with blocking parts 14; the blocking parts 14 are convex edges which are arranged at two sides of the rib plate 13 and perpendicular to the rib plate 13; the rib plates 13 can further improve the strength of the whole structure of the bent pipe 1.
The invention divides the closestool into three parts, namely the bent pipe, the urinal body and the edge, wherein the urinal body and the edge are formed separately and integrally, and the bent pipe is formed by bonding the first half pipe and the second half pipe which are formed separately and integrally, so that the first half pipe and the second half pipe can adopt a double-sided slurry structure, the slurry density of the inner wall and the outer wall of the bent pipe is consistent, the hardening degree is consistent, the bent pipe is not easy to deform and crack, and the strength and the yield of the closestool are improved. Meanwhile, the bent pipe with the double-sided slurry structure is high in strength, strong in supporting effect on the urinal main body and capable of further improving the strength of a closestool. In addition, the positioning device matched with each other is arranged on the first half pipe and the second half pipe, so that the bonding efficiency and accuracy of the bent pipe are improved.
Specifically, referring to fig. 4, in the present embodiment, the urinal body 2 includes a urinal 21 and a seat 22; a flushing hole 23 and a water guiding edge 24 are arranged in the urinal 21; the flushing hole 23 is arranged at the rear part of the urinal 21; the water guiding rim 24 extends from the flushing hole 23 toward the front end of the urinal 21 and protrudes inward of the urinal 21. The urinal body 2 of this structure can be formed without using a die small piece. It should be noted that, the conventional flushing structure is an arc-shaped concave structure, and the concave structure must be implemented by using small die pieces or bonding.
Further, the urinal 21 is provided with a mounting protrusion 25 on the outside for connection with the skirt 3.
Specifically, referring to fig. 5, in this embodiment, a mounting plate 31 for adhering the elbow 1 is provided on the bottom surface of the skirt 3, and positioning slots 32 for rapidly positioning the elbow 1 are provided on two sides of the mounting plate 31; the positioning clamping groove 32 is matched with the blocking part 14 in the structure of the bent pipe 1, so that the positioning bonding speed between the bent pipe 1 and the periphery 3 can be improved.

The top of the skirt 3 is also provided with a mounting concave part 33 for mounting the urinal body, and the mounting concave part is matched with a mounting convex part 25 arranged outside the urinal 21, so that the quick bonding of the urinal body 2 and the skirt 3 is realized.
Further, in another embodiment of the present invention, the toilet further includes a water tank.
In order to further improve the production efficiency, the first half pipe 11, the second half pipe 12 and the urinal body 2 in the present embodiment are molded by using the side press 4; the skirt 3 is formed by a vertical press 5.
The side press 4 is novel ceramic bathroom high-pressure forming equipment, the slip casting pressure is 0.8-1.2MPa, and the side press is provided with a plurality of sets of die sets, so that a plurality of green bodies can be formed at one time. Unlike common vertical hydraulic presses, the die opening direction is horizontal.
Specifically, referring to fig. 6, in the present embodiment, the side press 4 is provided with at least two sets of die sets; comprising at least one set of a first die set 41 for shaping said first half-pipe 11, at least one set of a second die set 42 for shaping said second half-pipe 12, and/or at least one set of a third die set 43 for shaping said urinal body 2; preferably, the side press 4 is provided with 5-8 die sets. The toilet is divided into three parts, wherein the first half pipe 11, the second half pipe 12 and the urinal main body 2 are smaller in part structure and can be molded by using the side compressor 4 with higher efficiency, and meanwhile, the first half pipe 11, the second half pipe 12 and the urinal main body 2 are smaller in part structure and high in hardening speed, and the production efficiency can be improved by compounding the first half pipe 11, the second half pipe 12 and the urinal main body 2.
Specifically, in the present embodiment, the molding time of the side press 4 is 10 to 25 minutes, preferably 15 to 22 minutes; too short a forming time can reduce the green strength.
Specifically, referring to fig. 7 and 8, in the present embodiment, the first die set 41 is composed of a first male die 44 and a first female die 45; the second die set 42 is composed of a second male die 46 and a second female die 47. The first punch 44, the first die 45, the second punch 46, and the second die 47 are sheet-shaped. The bent pipe is formed by adopting the male die and the female die, so that the bent pipe is of a double-sided slurry structure, and the strength of the bent pipe is greatly improved.
After the bent pipe is molded for two times, the bent pipe is made into a double-sided slurry structure, so that the strength is improved; however, the efficiency of forming the bent pipe is also reduced. To overcome the above drawbacks: firstly, the closestool is integrally divided into three blocks for molding, so that the molding efficiency of the urinal main body and the skirt is greatly improved; secondly, the first half pipe 11 and the second half pipe 12 are molded by adopting a side press with higher molding efficiency; finally, at least 4 mold cores 441 (461) are arranged on the first male die 44 and the second male die 46 for forming the first half pipe 11 and the second half pipe 12, so that the half pipe forming speed is increased; meanwhile, a positioning structure is arranged on the first half pipe 11 and the second half pipe 12, so that the bonding speed of the bent pipe is improved. The two components are combined, so that the integral forming efficiency of the closestool is not affected under the condition that the bent pipe adopts a double-sided slurry structure.
The use of a side press can improve production efficiency, but because the side press is a high-pressure forming device, as few die pieces as possible are needed. For this reason, the present invention improves the structure of the urinal body 2. In particular, see fig. 4; in this embodiment, the water guiding edge 24 of the urinal body 2 protrudes inward of the urinal. The urinal body 2 of this structure can be formed without using a die small piece. It should be noted that, the conventional flushing structure is an arc-shaped concave structure, and the concave structure must be implemented in a form of small mold pieces or adhesion, and cannot be formed at a time under high pressure.
In particular, see fig. 9; the molding pressure required is high due to the large volume of the skirt 3, so that the molding is performed by adopting the vertical press 5. The vertical press 5 comprises at least two groups of die sets; preferably, the vertical press 5 comprises two fourth die sets 51; the fourth die set 51 is composed of an upper die 52 and a lower die 53, the upper die 52 and the lower die 53 are in a block shape, and the upper die 52 is provided with a protrusion. The upper die 52 and the lower die 53 in the invention have reasonable structural design, so that the structure of the skirt double-sided pulp has large occupation ratio and higher strength; according to the invention, the skirt 3, the bent pipe 1 and the urinal main body 2 are formed separately, so that the volume of the skirt component is reduced, and hardening is easy.
The vertical press 5 provides a higher forming pressure and can be used to form larger components, but at a slower rate. In order to improve production efficiency, the invention independently forms the skirt 3, and has smaller volume, so that one vertical press 5 can accommodate 2 groups of die sets; meanwhile, the smaller edge 3 structure enables the die to be formed by adopting a two-piece die, and the die opening speed is high; furthermore, the hardening speed of the skirt 3 with a smaller structure is high; the three components are compounded, so that the forming efficiency of the skirt 3 is greatly improved. Preferably, in the present invention, the molding time of the vertical press 5 is 20 to 40 minutes, preferably 30 to 40 minutes.
It should be noted that, in the conventional toilet bowl, due to unreasonable blocking, a multi-piece mold (five-piece mold and four-piece mold) is often required to be used for molding. According to the invention, through reasonable block design and structural design, the forming speed of the urinal main body 2 and the skirt 3 is greatly improved; provides a good basis for the block forming of the bent pipe 1, so that the integral closestool still keeps high forming efficiency.
Correspondingly, referring to fig. 10, the embodiment also discloses a preparation method of the high-strength toilet, which comprises the following steps:
s1, forming a urinal main body and a skirt;
specifically, the slurry is injected into the third die set 43 provided in the side press 4 to mold the urinal body 2; placing for preset time after die opening to harden the die to obtain a urinal main body;

bonding the first half pipe 11 and the second half pipe 12, and placing and hardening to obtain an elbow pipe;
s3, adhering the bent pipe to the periphery;
specifically, the mounting plate 11 on the bottom surface of the skirt is coated with slurry, and the bent pipe 1 and the skirt 3 are bonded;
s4, bonding the urinal body to the skirt and the bent pipe to form a toilet body;
specifically, the skirt 3 and the urinal body are bonded by the slurry applied to the mounting recess 33; the urinal body 2 and the elbow 1 are bonded by the slurry coated on the upper surface of the elbow body.
After the bonding is completed, the toilet body is placed for a certain time, so that the toilet body is hardened.
