Description

Technical Field

[0001] The present invention relates to the technical field of sanitary equipment, and particularly relates to a positioning structure for a water tank model and a toilet mold. Background Art

[0002] When a one-piece toilet is manufactured, its production model includes a left side model, a right side model, a water channel movable block model, a ring plate model, a water tank movable block model, an inner pot movable block model, a bottom model, etc. When the mold is closed for grouting, the water tank movable block model needs to be fixed on the ring plate model. During daily grouting use, due to the fluidity of the slurry, the water tank movable block model is prone to displacement, resulting in inconsistent and non-compliant thickness of the product blank, and defective products during subsequent production drying and firing.

[0003] Chinese Patent Document CN108527618A discloses a toilet mold structure. Although the problem of displacement is solved by the cooperation of a positioning protrusion and a positioning groove, during the forming process of the toilet, a 90° wet blank turning operation is required, that is, the mold is turned 90° when the toilet is in a wet blank state.

[0004] Since the part of the water tank movable block model around the positioning groove is relatively thin, and during the wet blank turning operation, a large force will occur between the positioning protrusion and the positioning groove, which is likely to cause the water tank movable block to break, resulting in a short service life of the model, waste of production resources, low production efficiency, unstable production capacity and other problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a positioning structure for a water tank model and a toilet mold.

[0026] In order to enable those skilled in the art of the present technology to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the attached drawings and the best embodiments.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the attached drawings, and is 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 construed as a limitation to the present invention.

[0028] As shown in the figure, the present invention includes a ring plate model 1 and a water tank movable block model. A placement groove 6 is provided at the rear of the ring plate model 1. It is characterized in that the water tank movable block model includes a water tank front-side movable block 3 installed in the middle of the placement groove and a water tank left-side movable block 2 and a water tank right-side movable block 5 installed on both sides of the placement groove. The water tank front-side movable block 3 is integrally L-shaped. The water tank front-side movable block 3 specifically includes a front-side movable block positioning portion 301 that cooperates with the middle of the placement groove and a front-side movable block main body portion 302 on the front side above it. A water tank rear-side movable block 4 is embedded in the rear side above the front-side movable block positioning portion 301 of the water tank front-side movable block 3. Dividing the water tank movable block model into multiple movable blocks can reduce the weight of a single unit and facilitate the operation of the staff. A first protrusion 8 is provided in the middle of the placement groove. Both sides of the first protrusion 8 are respectively abutted against the front side surface 603 and the rear side surface of the placement groove. The front side surface 603 and the rear side surface of the placement groove are a pair of opposite side surfaces of the placement groove. A second protrusion 7 with a triangular longitudinal section is provided between both the left side surface of the placement groove and the right side surface 602 of the placement groove and the bottom surface 604 of the placement groove. The left side surface of the placement groove and the right side surface 602 of the placement groove are another pair of opposite side surfaces of the placement groove. A first positioning groove adapted to the first protrusion 8 is provided on the bottom surface of the front-side movable block positioning portion 301. Second positioning grooves adapted to the second protrusion 7 are provided on the bottom surfaces of both the water tank left-side movable block 2 and the water tank right-side movable block 5. Before the wet blank is turned over, the bottom surface 604 of the placement groove is in a horizontal state. After the wet blank is turned over, the bottom surface 604 of the placement groove is perpendicular to the horizontal plane, and the front side surface 603 of the placement groove is directly above the rear side surface of the placement groove. The function of the cooperation between the first protrusion 8 and the first positioning groove is to position the water tank front-side movable block 3 to prevent it from shifting, and it is also convenient for the installation of the water tank left-side movable block 2 and the water tank right-side movable block 5. During the process of turning over the wet blank, since both sides of the first protrusion 8 are respectively abutted against the front side surface 603 and the rear side surface of the placement groove, no large acting force will occur between the first protrusion 8 and the first positioning groove. At the same time, since it is the whole front-side movable block positioning portion 301 that is adapted to the middle of the placement groove, mainly the whole front-side movable block positioning portion 301 is stressed. Therefore, the water tank front-side movable block 3 is not easily broken. The function of the cooperation between the two pairs of second protrusions 7 and the second positioning grooves is to respectively position the water tank left-side movable block 2 and the water tank right-side movable block 5 to prevent them from shifting. During the process of turning over the wet blank, the longitudinal section of the traditional positioning protrusion is rectangular, and stress concentration will occur at the corner points where it extends into the positioning groove. In this solution, the longitudinal section of the second protrusion 7 is triangular, and no stress concentration point will occur. Therefore, the water tank left-side movable block 2 and the water tank right-side movable block 5 are also not easily broken. This technical solution can prevent the water tank movable block model from shifting. At the same time, during the process of turning over the wet blank, the water tank movable block model is not easily broken, the service life of the model is long, production resources can be saved, production efficiency can be improved, and production capacity can be stabilized.

[0029] The second protrusion 7 is in the shape of a triangular prism platform. The bottom area of the second protrusion 7 close to the front side surface 603 of the placement groove is larger than the other bottom area of the second protrusion 7. During the process of turning the wet blank, while increasing the force-bearing surface of the second protrusion 7, the volume of the second protrusion 7 can be minimized as much as possible, preventing the left and right movable blocks 2 and 5 of the water tank from breaking due to the relatively large second positioning groove. Increasing the force-bearing surface of the second protrusion 7 can further improve the stability of the corresponding movable block.

[0030] A third protrusion 11 is provided on the upper side surface of the front movable block positioning portion 301. A third positioning groove adapted to the third protrusion 11 is provided on the bottom surface of the rear movable block 4 of the water tank for positioning the rear movable block 4 of the water tank.

[0031] The upper side surface of the front movable block positioning portion 301 is lower than the upper side surface 601 of the placement groove. After installing the rear movable block 4 of the water tank, the upper part of the rear side surface of the placement groove will abut against one side of the bottom of the rear movable block 4 of the water tank, improving the stability of the rear movable block 4 of the water tank.

[0032] Embedded grooves 9 are provided above the respective joint surfaces between the upper movable block of the water tank, the rear movable block 4 of the water tank, the left movable block 2 of the water tank, and the right movable block 5 of the water tank, and magnets attracting each other are embedded therein, which can improve the adhesion force between the movable blocks and improve the overall stability of the water tank movable block model.

[0033] Weight-reducing cavities are provided on the opposite sides of the front movable block 3 of the water tank and the rear movable block 4 of the water tank, and on the opposite sides of the left movable block 2 of the water tank and the right movable block 5 of the water tank, which can further reduce the weight of each movable block and facilitate manual operation.

[0034] Vent holes 10 communicating with the weight-reducing cavity of the left movable block 2 of the water tank and the weight-reducing cavity of the right movable block 5 of the water tank respectively are provided on both sides of the weight-reducing cavity of the front movable block 3 of the water tank. After taking a mold of one of the front movable block 3 of the water tank, the rear movable block 4 of the water tank, the left movable block 2 of the water tank, and the right movable block 5 of the water tank, the vent holes 10 can prevent negative pressure from occurring between the remaining three movable blocks, facilitating subsequent mold-taking work.

[0035] This patent also discloses a toilet mold, including the above-mentioned water tank model positioning structure, which is characterized by including a ring plate model 1, an inner pot movable block model 16 provided above the front part of the ring plate model 1, a bottom model 13 provided above the inner pot movable block model 16, a water tank movable block model provided above the rear part of the ring plate model 1, a left side form model 15, a right side form model 12, and a water channel movable block model 14 horizontally surrounding the outer periphery of the ring plate model 1, which can prevent the water tank movable block model from shifting, and the water tank movable block model is not easily broken, improving production efficiency and stabilizing production capacity.

[0036] The structure of the present invention is simple, which can prevent the displacement of the water tank movable block model. At the same time, during the process of turning the wet blank, the water tank movable block model is not easily broken, has a long service life of the model, can save production resources, improve production efficiency, and stabilize production capacity. The two bottom surfaces of the second protrusion, one large and one small, increase the stress surface of the second protrusion while minimizing the volume of the second protrusion as much as possible, which can prevent the left and right movable blocks of the water tank from breaking due to the relatively large second positioning groove. After installing the rear movable block of the water tank, the upper part of the rear side of the placement groove will abut against one side of the bottom of the rear movable block of the water tank, improving the stability of the rear movable block of the water tank. The magnet can improve the adhesion between the movable blocks and enhance the overall stability of the water tank movable block model. The weight reduction cavity can further reduce the weight of each movable block, facilitating manual operation. After demolding one of the front movable block of the water tank, the rear movable block of the water tank, the left movable block of the water tank, and the right movable block of the water tank, the ventilation hole can prevent negative pressure from occurring between the remaining three movable blocks, facilitating subsequent demolding work.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
