Description

Technical Field

[0001] This invention relates to the field of sanitary ware, and in particular to a toilet cover mold, manufacturing method, and toilet cover. Background Technology

[0002] Toilets on the market typically require multiple parts to be injection molded separately, including the outer casing, inner liner, and seat. After injection, these parts are then glued together to form a complete toilet. Currently, the process for making the outer casing mold is basically the same: the entire mold is demolded, and then a concave and convex mold is used to produce the complete outer casing structure. In addition, the entire mold is often quite heavy, requiring multiple people to work together to remove it, and there is a risk of injury during the process.

[0003] Outerwear made using this conventional process generally suffers from the following problems:

[0004] 1. The casing process of traditional smart toilets is standardized, resulting in products with a rather monotonous appearance;

[0005] 2. Traditional smart toilet seat covers have high limitations in terms of personalization and cannot accurately meet customer requirements;

[0006] 3. The molds for traditional smart toilet covers are relatively heavy, requiring a high level of manpower. Summary of the Invention

[0007] The main objective of this invention is to overcome the limitations of existing toilet cover designs, which are often monotonous and the molds are heavy and inconvenient to handle. This invention proposes a toilet cover mold, manufacturing method, and toilet cover that breaks through the limitations of traditional toilet cover appearances and features a novel design.

[0008] The present invention adopts the following technical solution:

[0009] A toilet outer casing mold includes an outer mold, several inner molds, and a bottom mold. The outer mold has an open cavity, and the inner wall of the cavity has several first protrusions that are spaced apart circumferentially. Several inner molds are located inside the cavity and are distributed circumferentially, forming a groove. Each inner mold has several second protrusions on one side opposite the inner wall of the cavity, which are spaced apart circumferentially, and the second protrusions of the inner molds correspond to and fit with the first protrusions on the outer mold. The bottom mold is located at the opening and has a boss that inserts into the groove, which fits with the inner molds. A first cavity is formed between the inner wall of the outer mold containing the first protrusions, the side of the inner mold containing the second protrusions, and the bottom mold to allow the injection of mud to form the toilet outer casing.

[0010] The inner wall of the cavity includes an arc-shaped surface and a first plane. The two ends of the arc-shaped surface are respectively connected to the two ends of the first plane to form a cavity, and a number of first protrusions are formed on the arc-shaped surface.

[0011] A second plane is provided on the side of the boss opposite to the first plane, and a third plane is provided on the inner mold opposite to the first plane. A second cavity is formed between the first plane, the third plane and the second plane, and the second cavity is connected to the first cavity.

[0012] The internal molds include two first internal molds and two second internal molds. The two first internal molds are located at the rear of the cavity and are symmetrically distributed relative to the central axis of the cavity. The two second internal molds are located at the front of the cavity and are symmetrically distributed relative to the central axis of the cavity.

[0013] There is a gap between the first inner mold and the second inner mold, and there are also two third inner molds. The third inner molds are located at the gap between the first inner mold and the second inner mold, and the two third inner molds are symmetrically distributed relative to the central axis of the cavity.

[0014] The first inner mold has a first inclined surface on the side opposite to the third inner mold, the second inner mold has a second inclined surface on the side opposite to the third inner mold, and the third inner mold has third inclined surfaces on both sides to fit with the corresponding first and second inclined surfaces respectively.

[0015] The two third inclined surfaces on both sides of the third inner mold are designed to extend in opposite directions from one end near the central axis of the cavity to the other end near the inner wall of the cavity.

[0016] The outer mold includes a first outer mold and a second outer mold, which are symmetrically distributed relative to the central axis of the cavity; the first protrusion extends from the inner wall of the cavity near the opening towards the side away from the opening, and the first protrusion protrudes towards the center of the cavity; the second protrusion extends from the inner mold near the opening towards the side away from the opening, and the second protrusion protrudes outward away from the center of the cavity.

[0017] The lengths of several first protrusions may be the same or different, and the spacing between adjacent first protrusions may be the same or different; the lengths of several second protrusions may be the same or different, and the spacing between adjacent second protrusions may be the same or different.

[0018] The bottom mold includes a bottom plate located at the opening, and a boss located in the middle of one side of the bottom plate opposite the cavity. Several fourth inclined surfaces are provided on the outer periphery of the boss, and several fifth inclined surfaces are provided on the side of the inner mold opposite the boss. The several fifth inclined surfaces and several fourth inclined surfaces are fitted together one by one.

[0019] The fourth inclined surface is designed to extend at an angle toward the central axis of the cavity from the side closest to the bottom plate to the side furthest from the bottom plate.

[0020] A method for manufacturing a toilet cover, using the aforementioned toilet cover mold, includes the following steps:

[0021] 1) Insert several inner molds into the cavity of the outer mold in sequence, and make the second protrusion of the inner mold correspond to and fit the first protrusion on the outer mold one by one;

[0022] 2) Place the bottom mold in the opening and insert the boss into the empty groove formed by several inner molds, so that a first cavity is formed between the outer mold, inner mold and bottom mold;

[0023] 3) Inject grout into the grout inlet of the first cavity. After the grout fills the first cavity, let it stand for a while, and then release the grout.

[0024] 4) After the set molding time, the outer shell will be formed;

[0025] 5) Mold disassembly:

[0026] First, remove the bottom mold so that the boss is detached from the empty groove;

[0027] Then the inner mold of the middle region of the cavity wall is removed in a direction perpendicular to the central axis of the cavity;

[0028] Then remove the inner molds from the front and rear regions of the cavity wall;

[0029] Finally, remove the outer mold.

[0030] The specific steps are as follows: Several inner molds are sequentially inserted into the cavity of the outer mold.

[0031] At least two inner molds are placed symmetrically along the opening and relative to the central axis of the cavity in the front region of the cavity wall; and at least two inner molds are placed symmetrically along the opening and relative to the central axis of the cavity in the rear region of the cavity wall.

[0032] Then, place the remaining inner mold in the middle region of the cavity in a direction perpendicular to the central axis of the cavity and symmetrically relative to the central axis of the cavity.

[0033] An outer casing for a toilet, installed on the outer periphery of the toilet liner, is manufactured using a mold for an outer casing for a toilet as described above. It includes several plates, a first connecting part, and a second connecting part. The plates are spaced apart along the circumference of the toilet liner. The first connecting part is connected to one end of the plates along their length, and the second connecting part is connected to the other end of the plates along their length. The plates, the first connecting part, and the second connecting part form a hollow cavity to accommodate the toilet liner. The first connecting part is bonded to the outer periphery of the toilet liner.

[0034] It also includes a third connecting part, which is located at the rear of the toilet liner. One side of the third connecting part is connected to one end of the first connecting part and the second connecting part, and the other side of the third connecting part is connected to the other end of the first connecting part and the other end of the second connecting part.

[0035] The top of the toilet liner is a basin-shaped part; the side of the plate opposite the toilet liner is provided with a raised strip, and the raised strips of several plates form a support platform opposite the basin-shaped part, and the support platform is in contact with the bottom surface of the basin-shaped part.

[0036] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The mold of the present invention includes an outer mold, several inner molds and a bottom mold. The second protrusions of the several inner molds correspond to and fit with the first protrusions on the outer mold. The bottom mold is located at the opening and is provided with a boss that fits with the several inner molds. A first cavity is formed between the inner wall where the first protrusion of the outer mold is located, the side where the second protrusion of the inner mold is located and the bottom mold. By adopting this multi-part structure splitting method, the weight of a single module is greatly reduced, demolding is convenient, and the manpower requirement is reduced.

[0038] 2. The mold of the present invention divides multiple inner molds into a first inner mold, a second inner mold and a third inner mold, which are assembled and spliced ​​to form a cavity with the inner mold and the bottom mold. The outer mold, inner mold and bottom mold are provided with inclined surfaces to achieve mutual interlocking, increase friction and prevent falling off during installation or removal.

[0039] 3. In the outer jacket manufacturing method of the present invention, the outer mold, inner mold and bottom mold can be spliced ​​or disassembled separately during mold assembly and disassembly. The operation is simple, effortless, reduces the required manpower and improves safety.

[0040] 4. The jacket of the present invention comprises a plate, a first connecting part and a second connecting part, etc., forming a jacket with a hollow structure. Compared with traditional jackets, its weight is greatly reduced, breaking through the limitations of traditional appearance, with a novel shape, and can meet the personalized appearance requirements.

[0041] 5. In the outer casing of the present invention, a raised strip is provided on the side of the plate body opposite to the toilet liner, and a support platform is formed on the side of the raised strip of several plates opposite to the basin-shaped part so as to fit with the bottom surface of the basin-shaped part, making the fit between the two more stable.

[0064] See Figures 1 to 9 A toilet outer casing mold includes an outer mold 10, several inner molds 20, and a bottom mold 30. The outer mold 10 has a cavity 12 with an opening 11, and the inner wall of the cavity 12 has several first protrusions 13, which are spaced apart circumferentially along the cavity 12. The outer mold 10 has an overall shape similar to a toilet, that is, the front and sides of the outer mold 10 are arc-shaped, the rear side of the outer mold 10 is flat, the opening 11 is located on the top surface, and the bottom surface is closed.

[0065] Among them, see Figures 4-5 The outer mold 10 can be a one-piece structure or a split structure. Taking the split structure as an example, it includes a first outer mold 14 and a second outer mold 15. The first outer mold 14 and the second outer mold 15 are symmetrically distributed with respect to the central axis of the cavity 12, wherein the central axis of the cavity 12 extends along the front-back direction of the outer mold 10, dividing the outer mold 10 into a left-right symmetrical first outer mold 14 and second outer mold 15. The first protrusions 13 on the first outer mold 14 and the second outer mold 15 can also be symmetrically distributed with respect to the central axis. The first protrusions 13 extend from the side of the inner wall of the cavity 12 near the opening 11 toward the side away from the opening 11, that is, the first protrusions 13 extend from top to bottom, and the first protrusions 13 protrude toward the center of the cavity 12. The lengths of several first protrusions 13 may be the same or different, and the spacing between adjacent first protrusions 13 may be the same or different. The specific length, thickness, and spacing of the first protrusions 13 can be designed according to the shape of the outer jacket 50 to be produced, and are not limited here.

[0066] Furthermore, the inner wall of the cavity 12 enclosed by the outer mold 10 includes an arc-shaped surface 16 and a first plane 17. The two ends of the arc-shaped surface 16 are respectively connected to the two ends of the first plane 17 to form the cavity 12. A number of first protrusions 13 are formed on the arc-shaped surface 16. The length of the first protrusions 13 is less than the dimension of the inner wall of the cavity 12 in the vertical direction. No protrusions are provided on the first plane 17.

[0067] This invention provides several inner molds 20, which can reduce the weight of a single mold block. The inner molds 20 are located within the cavity 12 and distributed circumferentially around the cavity 12. The inner molds 20 form a groove, and can be arranged around the front and sides of the cavity 12, with the groove located in the center of the cavity 12. Each inner mold 20 has multiple second protrusions 21 on one side opposite the inner wall of the cavity 12. These second protrusions 21 are spaced circumferentially, and each second protrusion 21 of the inner mold 20 corresponds to and fits into a first protrusion 13 on the outer mold 10. Thus, a first protrusion 13 and a second protrusion 21 are arranged in pairs. Elongated holes 34 can be formed between adjacent pairs of first protrusions 13 and second protrusions 21. These elongated holes 34 are distributed circumferentially around the cavity 12, and the protrusion positions form the hollow structure 54 of the outer jacket 50 to be manufactured.

[0068] The inner molds 20 may be the same or different in size and shape; if different, they may be set according to their specific locations. The second protrusion 21 extends from the side of the inner mold 20 closest to the opening 11 toward the side furthest from the opening 11, that is, the first protrusion 13 extends from top to bottom, and the second protrusion 21 protrudes outward toward the center of the cavity 12. The lengths of the second protrusions 21 may be the same or different, and the length of the second protrusion 21 is less than the vertical dimension of the inner mold 20. The spacing between adjacent second protrusions 21 may be the same or different. The specific length, thickness, and spacing of the second protrusions 21 can be designed according to the shape of the outer jacket 50 to be produced, and are not limited here.

[0069] Furthermore, the plurality of inner molds 20 of the present invention include two first inner molds 22 and two second inner molds 23. The two first inner molds 22 are located at the rear of the cavity 12 and are symmetrically distributed relative to the central axis of the cavity 12; the two second inner molds 23 are located at the front of the cavity 12 and are symmetrically distributed relative to the central axis of the cavity 12. There is a gap between the first inner molds 22 and the second inner molds 23. The invention also includes two third inner molds 24, which are located at the gap between the first inner molds 22 and the second inner molds 23, and are symmetrically distributed relative to the central axis of the cavity 12. See also... Figure 3 Only one first inner mold 22, one second inner mold 23, and one third inner mold 24 are drawn.

[0070] To facilitate the installation of each inner mold 20, the first inner mold 22 has a first inclined surface 25 on the side opposite to the third inner mold 24, the second inner mold 23 has a second inclined surface 26 on the side opposite to the third inner mold 24, and the third inner mold 24 has corresponding third inclined surfaces 27 on both sides to fit with the corresponding first inclined surface 25 and second inclined surface 26. The draft angles on the mating surfaces of the first inner mold 22, second inner mold 23, and third inner mold 24 facilitate the insertion of the third inner mold 24 and allow it to interlock, increasing friction to prevent it from falling off during installation or removal. Specifically, the two third inclined surfaces 27 on both sides of the third inner mold 24 are designed to extend at opposite angles from one end near the central axis of the cavity 12 to the end near the inner wall of the cavity 12, making the cross-section of the third inner mold 24 resemble a trapezoid, facilitating the insertion of the gap between the first inner mold 22 and the second inner mold 23.

[0071] The bottom mold 30 is located at the opening 11 and has a boss 31 that inserts into the slot. The boss 31 fits against several inner molds 20. A first cavity 33 is formed between the inner wall of the first protrusion 13 of the outer mold 10, the side of the second protrusion 21 of the inner mold 20, and the bottom mold 30. The first cavity 33 is used to inject mud to form the outer shell of the toilet. The first cavity 33 may include several elongated holes 34, and a first connecting portion connecting one end of each elongated hole 34, and a second connecting portion connecting the other end of each elongated hole 34. A slurry inlet can be provided on the outer mold 10. This slurry inlet is connected to the first cavity 33 and may be one or two, for slurry injection.

[0072] The protrusion 31 of the present invention has a second plane 35 on the side opposite to the first plane 17, and the inner mold 20 opposite to the first plane 17 has a corresponding third plane 28. A second cavity 37 is formed between the first plane 17, the third plane 28 and the second plane 35. The second cavity 37 communicates with the first cavity 33. The shape of the second cavity 37 can be set according to the shape of the corresponding part of the outer mold 50, and is not limited here. The shape formed by the first cavity 33 and the second cavity 37 can be the shape of the outer mold 50 to be manufactured. The slurry inlet can be set at a suitable position on the area where the first plane 17 of the outer mold 10 is located.

[0073] See Figure 7 , Figure 8The bottom mold 30 includes a bottom plate 32, which is located at the opening 11 to close the opening 11. A boss 31 is located in the middle of one side of the bottom plate 32 opposite to the cavity 12. The outer periphery of the boss 31 is provided with a plurality of fourth inclined surfaces 36 distributed circumferentially. A plurality of inner molds 20 are provided with fifth inclined surfaces 29 corresponding to one side of the boss 31. The plurality of fifth inclined surfaces 29 and the plurality of fourth inclined surfaces 36 are fitted one-to-one, and the number of fourth inclined surfaces 36 corresponds to the number of inner molds 20. The fourth inclined surfaces 36 and fifth inclined surfaces 29 are provided as draft angles to facilitate the assembly and disassembly of the bottom mold 30. Specifically, the fourth inclined surfaces 36 are configured to extend inclinedly towards the central axis of the cavity 12 from the side near the bottom plate 32 to the side away from the bottom plate 32.

[0074] In practical applications of the present invention, a groove 18 may be provided on one side of the outer mold 10 relative to the opening 11. Then, the corresponding end faces of the several inner molds 20 and the bosses 31 placed in can cover the groove 18 to form a third cavity. The third cavity is also connected to the first cavity 33. The shape of the third cavity can be set according to the corresponding structural shape of the outer jacket 50 to be made, and is not limited here.

[0075] Based on this, the present invention also proposes a method for manufacturing a toilet cover, which is realized using the above-mentioned toilet cover mold, and includes the following steps:

[0076] 1) Insert several inner molds 20 into the cavity 12 of the outer mold 10 in sequence, and make the second protrusion 21 of the inner mold 20 correspond to and fit with the first protrusion 13 on the outer mold 10.

[0077] In this step, the outer mold 10 is first placed, that is, the first outer mold 14 and the second inner mold 23 are placed flat and fitted together. Then, several inner molds 20 are sequentially inserted into the cavity 12 of the outer mold, specifically:

[0078] At least two inner molds 20 are placed symmetrically along the opening 11 and relative to the central axis of the cavity 12 in the front region of the inner wall of the cavity 12; and at least two inner molds 20 are placed symmetrically along the opening 11 and relative to the central axis of the cavity 12 in the rear region of the inner wall of the cavity 12.

[0079] Then, the remaining inner mold 20 is placed in the middle region of the cavity 12 in a direction perpendicular to the central axis of the cavity 12 and symmetrically relative to the central axis of the cavity 12.

[0080] For example, two first inner molds 22 are inserted into the rear of the cavity 12 along their open ends, two second inner molds 23 are inserted into the front of the cavity 12 along their open ends, and two third inner molds 24 are inserted into the gap between the first inner molds 22 and the second inner molds 23 along a direction perpendicular to the central axis of the cavity 12. The first protrusions 13 and the second protrusions 21 are then fitted together in a one-to-one correspondence. The installation processes of the first inner molds 22 and the second inner molds 23 do not interfere with each other and do not require a specific order.

[0081] 2) Place the bottom mold 30 in the opening 11 and insert the boss 31 into the empty groove formed by several inner molds 20. The multiple fourth inclined surfaces 36 on the outer periphery of the boss 31 respectively fit with the fifth inclined surfaces 29 of the corresponding inner molds 20, so that a first cavity 33 is formed between the outer mold 10, the inner mold 20 and the bottom mold 30.

[0082] In this step, a second cavity 37 is formed between the first plane 17 of the cavity 12, the second plane 35 of the bottom mold 30, and the third plane 28 of the inner mold 20. The second cavity 37 is connected to the first cavity 33. If necessary, a third cavity can also be formed between the groove 18 on the side of the bottom mold 30 opposite to the opening 11 and the corresponding end faces of the inner mold 20 and the boss 31. The third cavity is connected to the first cavity 33.

[0083] 3) Inject slurry into the inlet of the first cavity 33. After the first cavity 33 is filled with slurry, allow it to stand, and then discharge the slurry. In this step, the injected slurry also flows to the second cavity 37 and the third cavity, avoiding the positions of the first protrusion 13 and the second protrusion 21. The specific flow direction of the slurry can be found in [reference needed]. Figure 14 The slurry inlet can also serve as a vent to prevent internal cracking caused by excessive internal pressure during firing.

[0084] 4) After the set molding time, the outer shell will be formed.

[0085] Furthermore, the present invention also includes a mold disassembly step 5): First, the bottom mold 30 is removed, so that the boss 31 is disengaged from the slot. Due to the fourth inclined surface 36 and the fifth inclined surface 29, the bottom mold 30 can be easily and quickly removed. Then, the inner mold 20 in the middle region of the inner wall of the cavity 12 is removed in a direction perpendicular to the central axis of the cavity 12. Due to the presence of the first inclined surface 25, the second inclined surface 26 and the third inclined surface 27, the inner mold 20 located in the middle can be easily removed. Then, the inner molds 20 in the front and rear regions of the inner wall of the cavity 12 are removed. Finally, the blank is caught by a support plate, and the outer mold 10 is removed.

[0086] This invention also proposes a toilet outer casing, installed around the outer periphery of the toilet liner 40, manufactured using the aforementioned toilet outer casing mold. See also Figures 10 to 13 The toilet bowl includes several plates 51, a first connecting part 52, and a second connecting part 53. The plates 51 are spaced apart along the circumference of the toilet bowl liner 40, and a hollow structure 54 is formed between adjacent plates 51. The first connecting part 52 is connected to one end of the plates 51 along their length, and the second connecting part 53 is connected to the other end of the plates 51 along their length. The plates 51, the first connecting part 52, and the second connecting part 53 form a hollow receiving cavity 55 to receive the toilet bowl liner 40. The first connecting part 52 is bonded to the outer periphery of the toilet bowl liner 40.

[0087] In addition, a basin-shaped part 41 is provided at the top of the toilet liner 40, and a protrusion 56 is provided on the side of the plate 51 opposite to the toilet liner 40. A support platform 57 is formed on the side of the protrusion 56 of the plate 51 opposite to the basin-shaped part 41. The support platform 57 is in contact with the bottom surface of the basin-shaped part 41, which can play a role in assisting to support the toilet liner 40.

[0088] Furthermore, it also includes a third connecting part 58, which is located at the rear of the toilet liner 40. One side of the third connecting part 58 is connected to one end of the first connecting part 52 and the second connecting part 53, and the other side of the third connecting part 58 is connected to the other end of the first connecting part 52 and the other end of the second connecting part 53.

[0089] In this invention, the outer casing 50, including the plate 51, the first connecting portion 52, and the second connecting portion 53, is formed by slurry molding within the first cavity 33. The plate 51 corresponds to the elongated hole in the first cavity 33, the first connecting portion 52 corresponds to the first connecting portion, and the second connecting portion 53 corresponds to the second connecting portion.
