Description

Technical Field

[0001] The utility model relates to the technical field of bathroom product production, in particular to a high-pressure five-opening mold structure for molding double toilets. Background Art

[0002] At present, the molds used to form double toilets mainly include toilet split molding molds and toilet integrated molding molds:

[0003] In the split-forming mold for toilets, for example, a Chinese patent document discloses a technical solution with a patent application number of 202223235025.9 and the name of “a split-forming mold for straight-edge toilets”. This technical solution mainly includes an inner liner mold with two first forming cavities and an outer shell mold with two second forming cavities. The inner liner mold is used to form the inner liner of the toilet, and the outer shell mold is used to form the supporting shell of the toilet. It can be seen from this that although the mold can form two identical toilet inner liners or supporting shells at a time, it can only produce split-type toilets. Subsequently, the two toilet parts need to be bonded and fixed, which increases the production process. Moreover, due to the different dryness and wetness of the bonding material and the two toilet parts, as well as the deviation in the accuracy of the docking, the bonding point of the two toilet parts is prone to cracking, deformation and other problems during the subsequent sintering process, resulting in water leakage and a low yield rate.

[0004] In the one-piece molding mold for toilets, for example, a Chinese patent document discloses a technical solution with a patent application number of 202222756301.X and the name of "A one-piece molding mold for straight-edge toilets". The technical solution mainly includes an upper mold, a lower mold, a rear mold and an internal movable block. The upper mold, the lower mold and the rear mold together form two toilet molding stations, which are used to mold toilet components with an inner tank and a supporting shell as an integrated structure. Although the mold can make the inner liner and the supporting shell into an integrated structure, solving the problem of easy cracking at the bonding point between the inner liner and the supporting shell, the mold is a three-opening mold structure consisting of an upper mold, a lower mold, and a rear mold. It can only form an inner liner and a supporting shell with complex structure on the top, bottom, and back surfaces, but cannot form the S-shaped siphon drain pipe structure of the toilet. It can only be assembled in a split combination to install the S-shaped siphon drain pipe on the toilet component composed of the inner liner and the supporting shell. This not only requires additional assembly steps, but also there will still be water leakage problems at the connection point, resulting in poor anti-leakage reliability of the produced toilet. It can be seen that the mold cannot form a truly complete toilet in one piece.

[0005] Therefore, in view of the above-mentioned technical problems existing in the existing molds for forming double toilets, it is very necessary to redesign and develop them to better meet people's application needs. Utility Model Content

[0006] The present utility model aims to address the aforementioned problems and deficiencies by providing a high-pressure, five-part mold structure for forming a double toilet. This mold structure can integrally mold the toilet's sewage basin, support base, and siphon drain pipe structure, thereby forming a complete toilet body. This significantly improves the toilet's anti-leakage performance, achieves a high yield rate, and reduces the number of production steps, effectively increasing toilet production efficiency. Furthermore, by providing two toilet molding chambers, two complete toilet bodies can be molded at once, further enhancing toilet production efficiency.

[0008] Preferably, a flow-guiding forming convex portion is sleeved in the sewage receiving basin forming cavity, and a flow-guiding structure for forming a funnel-shaped sewage receiving surface is formed between the flow-guiding forming convex portion and the sewage receiving basin forming cavity.

[0009] Preferably, a columnar molding protrusion is mounted in the support seat molding cavity, and an inner cavity structure for molding a hollow toilet support seat is formed between the columnar molding protrusion and the support seat molding cavity.

[0010] Preferably, the diversion forming convex portion is also provided with a convex column portion inserted into the support seat forming cavity, and the columnar forming convex portion is also provided with a receiving groove mounted on the convex column portion, and a sewage connecting pipe forming cavity is formed between the receiving groove and the convex column portion, which is connected to the siphon sewage pipe forming cavity.

In this way, the sewage receiving basin, support seat, and siphon sewage pipe structure of the toilet can be integrally molded to form a toilet embryo with a complete structure, solving the problem of easy cracking at the joints of the toilet components, greatly improving the anti-leakage performance of the toilet, and having a high yield rate. There is no need to set up a separate shell to achieve support, which serves the purpose of reducing the toilet production process and effectively improving the production efficiency of the toilet. In addition, by setting up two toilet molding chambers, two complete toilet embryos can be molded at one time, which can further improve the production efficiency of the toilet. At the same time, the high-pressure five-open mold structure is adopted, so that the two toilet molding chambers are formed by enclosing four molds. In this way, a toilet with a complex shape structure on all four sides can be molded, making it easier to manufacture the sewage receiving basin, support seat, and siphon sewage pipe structure of the toilet in one piece.

[0026] like Figures 1 to 3 As shown, the utility model discloses a high-pressure five-opening mold structure for forming a double toilet, comprising a middle mold 1, and a front mold 2, a rear mold 3, a left mold 4, and a right mold 5 enclosing the middle mold 1; the front side of the middle mold 1 and the front mold 2, the left mold 4, and the right mold 5 together enclose a toilet molding chamber 100, and the rear side of the middle mold 1 and the rear mold 3, the left mold 4, and the right mold 5 also together enclose a toilet molding chamber 100; the toilet molding chamber 100 includes a sewage receiving basin molding chamber 10, a support seat molding chamber 20, and a siphon drainage pipe molding chamber 30 that are interconnected. The utility model can integrally mold the sewage receiving basin, support seat, and siphon drainage pipe structure of a toilet to form a toilet embryo with a complete structure, greatly improving the anti-leakage performance of the toilet, achieving a high yield rate, and reducing the production process of the toilet, effectively improving the production efficiency of the toilet. At the same time, by providing two toilet molding chambers 100, two complete toilet embryos 200 can be molded at one time, which can further improve the production efficiency of toilets.

[0027] like Figure 5 As shown, the waste basin forming cavity 10 is provided with a diversion molding protrusion 101, and a diversion structure 102 for forming a funnel-shaped waste receiving surface is formed between the diversion molding protrusion 101 and the waste basin forming cavity 10. By providing the diversion structure 102, a funnel-shaped waste receiving surface can be formed on the waste basin of the toilet, which is very conducive to the rapid diversion of waste and is very reliable in use.

[0028] like Figure 5 As shown, the support seat forming cavity 20 is provided with a cylindrical forming protrusion 201, and an inner cavity structure 203 for forming a hollow toilet support seat is formed between the cylindrical forming protrusion 201 and the support seat forming cavity 20. This facilitates the formation of a hollow toilet support seat, which not only helps to control the use of raw materials and reduce the overall weight of the toilet, but also helps to ensure that the toilet support seat has a very reliable supporting effect.

[0029] like Figure 5 As shown, the diversion molding protrusion 101 is further provided with a protruding column portion 103 that penetrates the support seat molding cavity 20. The columnar molding protrusion 201 is further provided with a receiving groove 202 that is sleeved on the protruding column portion 103. A sewage connection pipe molding cavity 40 is formed between the receiving groove 202 and the protruding column portion 103 and is connected to the siphon sewage pipe molding cavity 30. In the case of a hollow structure of the toilet support seat, the provision of the sewage connection pipe molding cavity 40 can facilitate reliable connection and communication with the siphon sewage pipe molding cavity 30.

[0030] like Figure 3 As shown, a chassis forming cavity 50 is provided between the support base forming cavity 20 and the siphon drain pipe forming cavity 30. This is conducive to forming a chassis connecting the siphon drain pipe and the support base, making the formed toilet more stable.

[0031] like Figure 4 As shown, a connecting reinforcement plate forming cavity 60 is provided between the sewage basin forming cavity 10, the support base forming cavity 20, and the bottom plate forming cavity 50. The reinforcement plate forming cavity 60 is arranged to penetrate the siphon drain pipe forming cavity 30. This not only enhances the overall structural strength of the toilet, but also allows the slurry to enter each forming cavity very quickly and evenly during grouting, which is conducive to the production of high-quality toilets.

[0032] like Figure 4 As shown, the reinforcing vertical plate forming cavity 60 is further provided with a reinforcing flange forming groove 70. This can further enhance the overall structural strength of the toilet, and during grouting molding, the slurry can be quickly and evenly entered into each forming cavity, which is conducive to producing high-quality toilets.

[0033] like Figures 2 to 4 As shown, a liquid passage 701 is provided between the reinforced flange forming groove 70 and the siphon drain pipe forming cavity 30, and a grouting hole 702 connected to the liquid passage 701 is provided on the left mold 4 or the right mold 5. An exhaust hole (not shown in the figure) is also provided on the left mold 4 or the right mold 5, which can meet the needs of high-pressure grouting molding and ensure smooth transportation of grouting molding.

[0034] like Figure 5 As shown, the left mold 4 and the right mold 5 are each provided with a reinforced connecting cavity 80 for connecting the waste basin forming cavity 10 and the support base forming cavity 20. This further enhances the overall structural strength of the toilet and allows the slurry to enter the forming cavities very quickly and evenly during grouting, thus facilitating the production of high-quality toilets.

[0035] like Figures 2 to 4 As shown, a reinforcing protrusion 703 and a relief groove 704 are nested between the left mold 4 and the right mold 5, and the outlet of the grouting hole 702 extends through the upper surface of the reinforcing protrusion 703. This can give the outlet of the grouting hole 702 a high structural strength, thereby better being able to withstand high pressure, and can also enable the grouting hole 702 to output slurry upward more stably, thereby improving the quality of grouting molding.

[0036] like Figure 2As shown, the left mold 4 and the right mold 5 are provided with nested brackets 41 for respectively supporting the front mold 2, the middle mold 1, and the back mold 3. This can respectively play the role of positioning and supporting the front mold 2, the middle mold 1, and the back mold 3, which is conducive to improving the accuracy and reliability of installation and positioning.

[0037] In order to further improve the rapid positioning of each mold during mold closing and prevent loosening after mold closing, Figures 3 to 8 As shown, the front mold 2, middle mold 1, and back mold 3 are each provided with a nested positioning convex edge portion 11 and a nested positioning concave edge groove 411. Specifically, each positioning convex edge portion 11 is provided on the front mold 2, middle mold 1, and back mold 3, respectively, and each positioning concave edge groove 411 is provided on the corresponding nested bracket 41. Of course, the positions of the positioning convex edge portion 11 and the positioning concave edge groove 411 can also be interchanged, and the same positioning and anti-loosening functions can be achieved.

[0038] In order to further improve the rapid positioning of each mold during mold closing and prevent loosening after mold closing, Figures 3 to 8 As shown, the front mold 2, middle mold 1, and rear mold 3 are each provided with nested positioning protrusions 12 and positioning grooves 412 between their corresponding nested brackets 41. Specifically, each positioning protrusion 12 is provided on the front mold 2, middle mold 1, and rear mold 3, and each positioning groove 412 is provided on its corresponding nested bracket 41. Of course, the positions of the positioning protrusions 12 and positioning grooves 412 can also be interchanged, and the positioning and anti-loosening functions can still be achieved. Similarly, the left mold 4 and right mold 5 are also provided with nested positioning protrusions 12 and positioning grooves 412.

[0039] like Figure 1 As shown, the center mold 1, front mold 2, rear mold 3, left mold 4, and right mold 5 are each provided with a hoisting hole 13. This allows the high-pressure five-part mold structure to be hoisted on a hoisting device, facilitating the movement of the molds for closing and demolding. In actual applications, the hoisting device is a commonly used device for hoisting toilet molding molds. Its structure and specific operating principles are not further elaborated here.

[0040] After the injection molding is complete, the left and right molds 4 and 5 are removed first, followed by the front mold 2, and then the middle mold 1 or the rear mold 3. Finally, the formed toilet body can be disassembled, meeting the requirements of opening the mold and removing the molded product. The toilet seat can be installed on the toilet by integral molding or by separate assembly.

[0041] In actual application, the flow guide molding protrusions 101 and the columnar molding protrusions 201 can be arranged on the middle mold 1, the front mold 2, the rear mold 3, the left mold 4, or the right mold 5 according to actual production requirements. Preferably, the two flow guide molding protrusions 101 are respectively arranged on the middle mold 1, and the two columnar molding protrusions 201 are respectively arranged on the front mold 2 and the rear mold 3.
