Description

Technical Field

[0001] This utility model belongs to the sanitary ware industry, specifically the field of toilet manufacturing equipment, and more specifically relates to a general-purpose mold for toilet manufacturing. Background Technology

[0002] Toilets, as commonly used sanitary ware, are typically manufactured using a mold injection molding process. Current toilet production molds consist of three parts: a mold for the inner cavity and top of the toilet bowl; a mold for the side walls and concealed pipes; and a mold for the bottom and drainage system. Taking a four-part inverted mold as an example, the lower mold forms the inner cavity and top of the toilet bowl, the upper mold forms the bottom and drainage system, and the side molds form the side walls and concealed pipes. This modular mold design facilitates demolding and detailed processing, enabling the efficient production of toilets with complex structures.

[0003] However, the distance from the wall to the toilet (i.e., the distance from the center point of the drain outlet to the wall) is a crucial parameter affecting its installation and use. When producing toilets with various wall distance specifications such as 300mm and 400mm, existing toilet molds are generally not universally compatible due to significant differences in drain outlet location and pipe structure between different wall distance specifications. Therefore, manufacturers need to build separate production lines and mold systems for producing toilets with different wall distance specifications. This not only increases equipment investment costs but also complicates production management and reduces production efficiency. Furthermore, producing toilets with multiple wall distance specifications on a single production line requires stopping the machine to replace the entire set of molds, resulting in excessive downtime and severely impacting production efficiency.

[0004] Furthermore, existing toilet sidewall and concealed pipe molding mold designs are typically tied to toilets with specific wall spacing specifications, failing to flexibly adapt to varying wall spacing requirements. This limitation not only increases mold development and maintenance costs but also restricts the flexibility and versatility of the production line. Utility Model Content

[0005] This invention addresses the technical problem of existing toilet molds lacking versatility in producing toilets with different wall spacing specifications, increasing mold development costs, and reducing production line efficiency. It provides a universal toilet production mold. This multi-specification wall spacing replaceable toilet bottom and drainage system forming mold can produce toilets with various wall spacing specifications without requiring replacement of the toilet bowl inner cavity and top forming molds, or the toilet sidewall and concealed pipe forming molds. This achieves mold universality, reduces costs, allows for rapid specification switching, significantly reduces downtime, and improves production efficiency.

[0006] The technical solution adopted by this utility model is: to provide a universal mold for toilet production, including a toilet bowl inner cavity and top forming mold, a toilet side wall and concealed pipe forming mold, characterized in that: it also includes a multi-specification wall distance replacement toilet bottom and drainage system forming mold, and the toilet bottom and drainage system forming mold is provided with a sewage outlet forming structure and a sewage pipe bottom wall forming structure.

[0007] The multi-specification wall distance replacement toilet bottom and drainage system molding mold can be replaced and assembled on the mold, thereby enabling the production of toilets with different wall distances. Since there is no need to replace the toilet bowl inner cavity and top molding mold and the toilet side wall and concealed pipe molding mold, the mold is universalized, reducing costs, quickly switching specifications, greatly reducing downtime, and improving production efficiency.

[0008] To further optimize this technical solution, the distance between the sewage outlet wall and the sewage outlet forming structure is 210mm-400mm.

[0009] The drain outlet molding structure is positioned according to the wall distance specifications to adjust the wall distance of the toilet drain outlet, making it flexible in use.

[0010] To further optimize this technical solution, the drain outlet forming structure includes a groove set on the bottom of the toilet and the forming mold of the drainage system. The groove corresponds to the position of the drain pipe core mold on the side wall of the toilet and the forming mold of the concealed pipe. A protrusion is coaxially set in the groove.

[0011] After the slurry is filled into the groove, it forms an outward-protruding drain outlet, and the protrusion forms the inner wall of the drain outlet.

[0012] To further optimize this technical solution, grouting holes are provided on the molding mold of the toilet bottom and drainage system or on the molding mold of the toilet bowl cavity and top; the grouting holes are located on the protrusions of the molding mold of the toilet bottom and drainage system, and the grouting holes penetrate through the molding mold of the toilet bottom and drainage system.

[0013] The position of the grouting hole is adjusted according to the application of the production mold and the selection of the production method. When the inverted mold production method is used, the grouting hole is located on the protrusion of the toilet bottom and the drainage system forming mold, and the grouting hole penetrates through the toilet bottom and the drainage system forming mold, which is flexible in use.

[0014] To further optimize this technical solution, the bottom wall forming structure of the sewage pipe is a plane set on the bottom of the toilet and the forming mold of the drainage system, and the plane corresponds to the position of the sewage pipe core mold on the side wall of the toilet and the forming mold of the concealed pipe.

[0015] The planar structure of the bottom wall of the sewage pipe ensures smooth sewage discharge.

[0016] To further optimize this technical solution, the bottom wall forming structure of the sewage pipe is a sloping boss set on the bottom of the toilet and the forming mold of the drainage system. The sloping boss corresponds to the position of the sewage pipe core mold on the side wall of the toilet and the forming mold of the concealed pipe, and the sloping surface of the sloping boss is set to be inclined upward from front to back.

[0017] The sloping boss gives the bottom wall of the formed sewage pipe a slope, allowing sewage to slide down the slope to the sewage outlet, ensuring the sewage discharge effect.

[0018] To further optimize this technical solution, the bottom wall forming structure of the sewage pipe includes a sealing boss fixed to the bottom of the toilet and the forming mold of the drainage system. The sealing boss is inserted and engaged with the sewage pipe core mold on the side wall of the toilet and the forming mold of the concealed pipe.

[0019] The plugging of the protrusion and the core mold of the drain pipe partially blocks the drain pipe, causing the drain outlet to shift, thus enabling the production of toilets with other wall distance specifications. The operation is simple, the use is flexible, and the utilization rate of the production line is improved.

[0020] To further optimize this technical solution, the sealing protrusion is positioned in front of the drain outlet forming structure, and the shape of the sealing protrusion corresponds to the drain pipe core mold on the toilet side wall and the concealed pipe forming mold, and is press-fitted to it.

[0021] The sealing boss is located on the front side of the sewage outlet forming structure, so that the sewage outlet moves backward along the sewage pipe. The sealing boss corresponds to the shape of the sewage pipe core mold and has an interference seal, which enhances the sealing effect, thereby forming sewage outlets with other wall distance specifications.

[0022] To further optimize this technical solution, the toilet sidewall and concealed pipe forming mold includes a left mold and a right mold. The left mold and the right mold are mortise and tenon connected to the toilet bowl cavity and top forming mold. The left mold and the right mold are connected to the toilet bottom and drainage system forming mold by means of positioning pins.

[0023] The left and right molds are easy to assemble and disassemble, making demolding convenient and flexible. The left and right molds are connected to the inner cavity and top forming mold of the toilet bowl with tenons and mortise joints to enhance the connection strength. The left and right molds are connected to the bottom and drainage system forming mold of the toilet with positioning pins to ensure the mold closing accuracy and improve the forming accuracy of the toilet.

[0024] To further optimize this technical solution, the positioning pin includes positioning keys set on the top surface of the left mold and the top surface of the right mold, and positioning grooves set on the bottom of the toilet and the forming mold of the drainage system to engage with the positioning keys.

[0025] The locating key provides positioning guidance for the locating slot, ensuring mold closing accuracy.

[0026] The beneficial effects of this utility model are as follows:

[0027] 1. The replaceable structure of the toilet bottom and drainage system molding mold allows for the production of toilets with various wall distance specifications on a single production line. This eliminates the need to replace major mold components such as the inner cavity and top molding molds of the toilet bowl, as well as the side wall and concealed pipe molding molds. This makes mold production more versatile, reduces mold costs and production complexity, and allows for quick switching of production specifications, reducing downtime and improving production line utilization.

[0028] 2. When the sealing boss is inserted into the inner cavity of the toilet bowl and the core mold of the drain pipe on the top forming mold, the front side of the drain pipe is sealed, the length of the drain pipe is shortened, and the drain outlet is moved back to produce a drain outlet with a wall distance of 300 mm. Because the drain outlet baffle seals the front of the drain pipe, the accumulation of sewage is avoided, ensuring the performance of the toilet.

[0029] 3. The universal mold for toilet production can be applied to gypsum grouting molding method, workstation high-pressure grouting method, continuous high-pressure grouting production line, and low-pressure fast drainage technology, and has versatility. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example 1

[0038] Please see the appendix Figure 1-3 The general-purpose mold for toilet production includes a toilet bowl cavity and top forming mold 1, a toilet side wall and concealed pipe forming mold 2, and a toilet bottom and drainage system forming mold 3. Taking an inverted four-part plaster toilet mold as an example, when switching between 300mm and 400mm wall spacing specifications on the production line, the upper mold is the toilet bottom and drainage system forming mold 3, forming the bottom surface and drain outlet of the toilet; the side mold is the toilet side wall and concealed pipe forming mold 2, forming the outer surface of the toilet and the drain pipe; and the lower mold is the toilet bowl cavity and top forming mold 1, forming the toilet bowl and the top surface of the toilet. The toilet side wall and concealed pipe forming mold 2 includes a detachable left side mold 201 and a right side mold 202, which are connected to the toilet bowl cavity and drainage system forming mold 3. The top forming mold 1 is connected by mortise and tenon joints to ensure connection strength. The top surfaces of the left mold 201 and the right mold 202 are fixedly equipped with positioning pins. The positioning pins include positioning keys 5 set on the top surfaces of the left mold 201 and the right mold 202. The bottom surface of the toilet bottom and drainage system forming mold 3 is provided with a positioning groove 6 that matches the positioning key 5. The positioning groove 6 is engaged with the positioning key 5, thereby positioning and constraining the toilet bottom and drainage system forming mold 3. The top surfaces of the left mold 201 and the right mold 202 are provided with slots. The toilet bottom and drainage system forming mold 3 is provided with a matching docking slot. The slots and docking slots are fixed by means of pins to ensure strength and positioning accuracy, and further ensure forming accuracy.

[0039] Please see the appendix Figure 5 Appendix Figure 6The toilet bottom and drainage system forming mold 3 is provided with a drain outlet forming structure 301. The drain outlet wall distance of the drain outlet forming structure 301 is 210mm-400mm, which can be used to change the production of toilets with various wall distance specifications, thereby improving production flexibility. The drain outlet forming structure 301 includes a groove 3011 provided on the toilet bottom and drainage system forming mold 3. The groove 3011 corresponds to the drain pipe core mold position on the toilet side wall and concealed pipe forming mold 2. A protrusion 3012 is coaxially provided in the groove 3011. A grouting hole 3013 is provided on the toilet bottom and drainage system forming mold 3 or on the toilet bowl cavity and top forming mold 1. 013 is located on the protrusion of the toilet bottom and drainage system molding mold 3, and the grouting hole 3013 penetrates the toilet bottom and drainage system molding mold 3 for injecting molding material into the mold. After the grout is injected into the groove 3011, it forms an outwardly protruding sewage outlet, while the protrusion 3012 forms the inner wall of the sewage outlet. The sewage pipe bottom wall molding structure 4 is a plane set on the toilet bottom and drainage system molding mold 3. The plane corresponds to the position of the sewage pipe core mold on the toilet side wall and concealed pipe molding mold 2. The plane on the toilet bottom and drainage system molding mold 3 constitutes a sewage pipe with a plane bottom wall structure, thereby directly molding a toilet that meets the 400mm wall distance. Example 2

[0040] Please see the appendix Figure 4 The bottom wall forming structure 4 of the sewage pipe is a sloping boss 401 set on the bottom of the toilet and the forming mold 3 of the drainage system. The sloping boss 401 corresponds to the sewage pipe core mold on the side wall of the toilet and the forming mold 2 of the concealed pipe. The sloping boss 401 is set to be inclined upward from front to back. The sloping boss 401 makes the bottom wall of the formed sewage pipe have a slope, so that the sewage slides down the slope to the sewage outlet, ensuring the sewage discharge effect. The sloping boss 401 is provided with a groove 302 on its periphery. The groove 302 is set on the bottom of the toilet and the forming mold 3 of the drainage system. After the slurry is formed in the groove 302, it forms an outward protruding support on the bottom surface of the toilet to support the toilet. Example 3

[0041] Please see the appendix Figure 6The drain pipe bottom wall forming structure 4 includes a sealing boss 402 fixed to the toilet bottom and drainage system forming mold 3. A groove 302 is provided around the sealing boss 402. The groove 302 is set on the toilet bottom and drainage system forming mold 3. After the slurry is formed in the groove 302, it forms an outwardly protruding support on the bottom surface of the toilet to support the toilet sealing boss 402 in insertion and engagement with the drain pipe core mold on the toilet side wall and concealed pipe forming mold 2. The sealing boss 402 is set on... In front of the drain outlet forming structure 301, the sealing boss 402 corresponds to the shape of the drain pipe core mold and is press-fitted to it. The sealing boss 402 is located at the frontmost side of the bottom of the drain pipe and partially blocks the front side of the drain pipe core mold, thereby causing the drain outlet to move backward along the drain pipe core mold to produce a toilet drain outlet with a wall distance of 300 mm. After the drain pipe is formed, its front side is sealed, which effectively reduces the accumulation of sewage in the drain pipe during use, thus improving hygiene performance and reducing the risk of blockage.

[0042] The working principle of the universal mold for toilet production is as follows: When producing toilets with a wall distance of 400mm, the drain outlet forming structure 301 of the toilet bottom and drainage system forming mold 3 is located at the front of the bottom of the drain pipe, which can directly form a toilet product that meets the 400mm wall distance requirement. When producing toilets with a wall distance of 300mm, a different toilet bottom and drainage system forming mold 3 structure is used, namely, the drain pipe bottom wall forming structure 4 is located at the front of the bottom of the drain pipe. The sealing boss 402 equipped therein has an interference seal with the drain pipe core mold of the toilet side wall and concealed pipe forming mold 2, which seals the front of the drain pipe, thereby shortening the length of the drain pipe after forming. At the same time, the drain outlet forming structure 301 is moved to the rear of the sealing boss 402, so that the final formed drain outlet position meets the 300mm wall distance requirement. The sealing boss 402 not only enables wall distance adjustment by sealing the front side of the drain pipe, but also effectively reduces the accumulation of waste in the drain pipe during use, thus improving hygiene and reducing the risk of blockage. The multi-specification replaceable structure of the toilet bottom and drainage system molding mold 3 allows for the production of toilets with various wall distances without the need to replace key mold components such as the toilet bowl inner cavity and top molding mold 1, and the toilet side wall and concealed pipe molding mold 2. This shortens the toilet specification production changeover time, significantly reduces downtime compared to traditional production methods, improves production line utilization, and reduces mold costs and production complexity.
