[0012] Furthermore, the one-piece molding method for the smart toilet seat includes the following steps: Intelligent toilet seat molding: Activate the telescopic cylinder to close the upper and lower molds, then insert the injection gun into the injection port and inject the injection liquid into the cavity formed by the upper and lower molds; Cooling and molding: Coolant is pumped into the mold through a coolant connection pipe to achieve rapid cooling. Coolant filtration: To prevent impurities in the coolant from entering the cooling channels inside the upper mold, the coolant first flows into the filter box, is filtered through the filter screen inside the filter box, and then flows into the upper mold. Filter cleaning: When the upper and lower molds are closed, the retaining plate is inserted into the insert plate. During insertion, the groove is compressed, and the gas inside the groove is discharged into each of the second air storage bladders through the third exhaust pipe. The second air storage bladders expand, pushing each slide plate to move, which in turn drives the elastically connected cleaning plate to clean the corresponding filter screen sidewalls. Water blowing: To prevent coolant residue in the upper mold, when the tube is inserted into the sleeve during mold closing, the extrusion block is squeezed. At this time, the elastically set tube is inserted into the insertion port to limit and fix the top cover plate. The gas inside the sleeve lifts the cover plate, and the gas is discharged into the insertion tube through the vent plate, and lifts the push plate. When the upper mold is raised to remove the mold, the insertion tube rises from inside the sleeve. When the insertion tube is completely raised from inside the sleeve, the extrusion block pops out and the insertion block moves out from inside the insertion port. At this time, the third reset spring pushes the push plate to reset. During the reset, the gas inside the insertion tube is discharged to the upper vent plate through the fourth exhaust pipe. With the cooperation of the upper vent plate, it is discharged into the upper mold, blowing out the coolant in the upper mold cooling channel.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses multiple sets of spaced filter screens to perform multi-stage filtration of the coolant entering the cooling channel, which can effectively intercept impurities in the coolant, prevent impurities from adhering to the inner wall of the cooling channel and causing blockage, ensure the stable flow rate of the coolant, and avoid a decrease in cooling efficiency. 2. The extrusion action during the mold closing process synchronously drives the cleaning plate to automatically clean the surface of the filter screen. Impurities intercepted by the filter screen can be automatically scraped off each time the mold closes, eliminating the need for staff to periodically disassemble the mold to clean the filter components. This reduces manual maintenance operations, does not interrupt the production process, and effectively improves production efficiency.

[0014] 3. By using the mold opening action to synchronously introduce compressed gas into the cooling channel inside the upper mold, the residual coolant after the cooling operation can be completely blown out, avoiding the impact of coolant residue on the mold closing accuracy and the molding quality of the next injection molding operation, thus ensuring the finished product qualification rate of the smart toilet seat.

[0017] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0018] Example 1 Please see Figures 1 to 12 This invention provides a technical solution: an integrated molding mold and molding method for a smart toilet seat, comprising: The upper mold 1 is provided with an injection port 2 for injection molding, and a matching lower mold 3 is provided below the upper mold 1. A base plate 11 is installed at the lower end of the lower mold 3. A filtration assembly is used to filter the coolant used to cool the molding cavity formed by the upper mold 1 and the lower mold 3. The filtration assembly includes a filter box 6 that communicates with the upper mold 1, and a filter screen 17 is provided inside the filter box 6. The liquid blowing assembly is used to blow out the coolant inside the upper mold 1. The liquid blowing assembly includes a coolant connecting pipe 7 that is connected to the filter box 6, and an insert 10 is provided on the lower surface of the coolant connecting pipe 7. A sleeve 8 is provided on the bottom plate 11 at a position below the insert 10.

[0019] In the above technical solution: after the upper mold 1 and the lower mold 3 are closed, the injection liquid is injected into the molding cavity through the injection port 2 to produce the smart toilet seat. After injection molding is completed, coolant is injected into the upper mold 1 to cool the smart toilet seat. Before the coolant is injected into the upper mold 1, it is filtered through a filter assembly to prevent impurities in the coolant from entering the cooling channel inside the upper mold 1 and adhering to the inner wall of the cooling channel. The liquid blowing assembly can blow out the coolant from the internal channel of the upper mold 1.

[0020] Example 2 like Figure 1 As shown, the integrated molding mold and molding method for the smart toilet seat disclosed in Embodiment 2 of the present invention are basically the same in structure as those in Embodiment 1, except that: A lifting assembly is provided between the upper mold 1 and the injection port 2, which is used to drive the upper mold 1 to rise and fall relative to the injection port 2; The lifting assembly includes four sets of fixing frames 4 installed on the lower end side wall of the upper mold 1. The four sets of fixing frames 4 are respectively installed on the two side walls of the fixing frames 4, and each fixing frame 4 is equipped with a telescopic cylinder 5. The output end of each telescopic cylinder 5 is fixedly connected to the upper surface of the corresponding base plate 11.

[0021] In the above technical solutions: After the injection molding operation is completed, the telescopic cylinder 5 drives the upper mold 1 to move upward as a whole, so that the upper mold 1 and the lower mold 3 are separated, and the molded smart toilet seat can be taken out. The four sets of telescopic cylinders 5 work in sync, which can ensure the stability of the upper mold 1 during the lifting process, avoid misalignment when the mold is closed, and ensure molding accuracy.

[0022] Example 3 like Figures 2-5 As shown, the integrated molding mold and molding method for the smart toilet seat disclosed in Embodiment 3 of the present invention are basically the same in structure as those in Embodiment 2, except that: The filter box 6 is equipped with a filter box cover 12, and the filter box cover 12 and the filter box 6 are fixedly connected by bolts; The filter screen 17 is installed at the lower end of the filter box cover 12, and the filter screen 17 is fixed inside the filter box 6 by the filter box cover 12; The filter screen 17 is provided in multiple sets, and the multiple sets of filter screens 17 are distributed at intervals. A sealing ring 15 is provided at the lower end of the filter box cover 12; The lower end of the filter box cover 12 is provided with a first storage groove 18. A compression plate 16 is inserted into the inside of the first storage groove 18. A first air storage bag 19 is provided between the upper end of the compression plate 16 and the top of the inside of the first storage groove 18. A first exhaust pipe 20 is provided between the first air storage bag 19 and the sealing ring 15. The filter box cover 12 has an air storage chamber 22 inside, and a sealing plate 23 is provided inside the air storage chamber 22. A first return spring 24 is provided between the side wall of the sealing plate 23 and the inner wall of the air storage chamber 22. A second exhaust pipe 21 is provided between the gas storage chamber 22 and the first exhaust pipe 20.

[0023] In the above technical solutions: Multiple sets of spaced filter screens 17 can filter the coolant step by step, which can effectively improve the interception effect of impurities and prevent impurities from entering the cooling channel and causing blockage. The filter box cover 12 is connected to the filter box 6 by bolts. When the filter screen 17 needs to be maintained or replaced, the bolts can be removed and the filter box cover 12 can be taken off to complete the operation, making maintenance more convenient. Once the filter box cover 12 is installed, the sealing ring 15 can seal the connection between the filter box cover 12 and the filter box 6 to prevent coolant leakage. During the mold closing process, the extrusion plate 16 is compressed, and the extrusion plate 16 compresses the first air storage bladder 19. After the first air storage bladder 19 is compressed, the internal gas can be discharged into the sealing ring 15 through the first exhaust pipe 20 to ensure the sealing effect. Excess gas enters the air storage chamber 22 through the second exhaust pipe 21 and pushes the sealing plate 23 to compress the first return spring 24 to ensure sufficient gas inside the sealing ring 15.

[0024] Example 4 like Figures 6-9 As shown, the integrated molding mold and molding method for the smart toilet seat disclosed in Embodiment 4 of the present invention are basically the same in structure as those in Embodiment 3, except that: The bottom of the filter box 6 is provided with a groove 25 corresponding to the position of each filter screen 17, and a sliding plate 27 is slidably arranged inside the groove 25; A cleaning plate 28 is elastically connected to the side wall of the slide plate 27 at a position corresponding to the side wall of the filter screen 17, and the cleaning plate 28 is elastically connected to the side wall of the filter screen 17.

The upper end of the base plate 11 is provided with a support plate 14 that can be inserted into the groove 31 at the position corresponding to the groove 31.

[0025] In the above technical solutions: During each mold closing operation, the process of the retaining plate 14 inserting into the insert plate 13 simultaneously compresses the third air storage bladder 32. After being compressed, the third air storage bladder 32 delivers the internal gas to each of the second air storage bladders 26 through the third exhaust pipe 33. After the second air storage bladders 26 inflate, they push the sliding plate 27 to slide along the slide groove 25, causing the cleaning plate 28 to move closely against the side wall of the filter screen 17, scraping off the impurities intercepted by the side wall of the filter screen 17. There is no need for manual periodic disassembly of the filter box 6 to clean the filter screen 17. The impurity cleaning can be automatically completed by each mold closing action, reducing the frequency of manual maintenance and improving the convenience of using the device.

[0026] The second return spring 30 can push the slide plate 27 to return to its original position after the abutment plate 14 is pulled out, thus preparing for the next cleaning operation.

[0027] Example 5 like Figures 10-12 As shown, the integrated molding mold and molding method for the smart toilet seat disclosed in Embodiment 5 of the present invention are basically the same in structure as those in Embodiment 4, except that: The coolant connection pipe 7 is connected to the coolant tank, and the coolant flows from the coolant tank to the interior of the upper mold 1 through the coolant connection pipe 7 for cooling. The base plate 11 is provided with a first fixing plate 9 at a position below the insertion tube 10, and the sleeve 8 is installed on the first fixing plate 9. Ventilation plates 38 are installed at both the upper and lower ends of the inner cannula 10. A cover plate 39 is inserted into the ventilation plate 38, and one end of the cover plate 39 passes through the ventilation plate 38. A fourth return spring 40 is sleeved on the outside of the end of the cover plate 39 that passes through the ventilation plate 38.

The inner wall of the insertion tube 10 is provided with a fourth exhaust pipe 37, and the two ends of the fourth exhaust pipe 37 are respectively located above the bottom cover plate 39 and between the second fixing plate 34 and the top ventilation plate 38.

[0028] In the above technical solution: In order to prevent coolant residue in the upper mold 1, when the mold is closed, the insert tube 10 is inserted into the sleeve 8 and the extrusion block 42 is squeezed. At this time, the elastically set insert block 47 is inserted into the insert 46 to limit and fix the top cover plate 39. The gas inside the sleeve 8 lifts the cover plate 39, and the gas is discharged into the insertion tube 10 through the vent plate 38, and lifts the push plate 36. When the upper mold 1 is lifted to remove the mold, the insertion tube 10 is lifted from the inside of the sleeve 8. When the insertion tube 10 is completely lifted out of the inside of the sleeve 8, the extrusion block 42 pops out, and the insertion block 47 moves out from the insertion port 46.

9. A method for integrally molding a smart toilet seat, characterized in that, Including the one-piece molding mold for the smart toilet seat as described in any one of claims 1-8, the one-piece molding method for the smart toilet seat includes the following steps: Intelligent toilet seat molding: Start the telescopic cylinder (5) to close the upper mold (1) and the lower mold (3), and then insert the injection gun into the injection port (2) to inject the injection liquid into the cavity formed by the upper mold (1) and the lower mold (3); Cooling and molding: Cooling liquid is discharged into the mold (1) through the connection of the coolant connection pipe (7) to achieve rapid cooling; Coolant filtration: In order to prevent impurities in the coolant from entering the cooling channel inside the upper mold (1), the coolant first flows into the filter box (6), and after being filtered by the filter screen (17) inside the filter box (6), it flows into the upper mold (1). Cleaning of filter screen (17): When the upper mold (1) and lower mold (3) are closed, the abutment plate (14) is inserted into the insert plate (13). When inserted, it compresses the groove (31). The gas inside the groove (31) is discharged into each of the second air storage bags (26) through the third exhaust pipe (33). The second air storage bags (26) expand, pushing each slide plate (27) to move, thereby driving the elastically connected cleaning plate (28) to clean the side wall of the corresponding filter screen (17): Blowing water: In order to prevent coolant residue in the upper mold (1), when the mold is closed, the insert (10) is inserted into the sleeve (8) and the extrusion block (42) is squeezed. At this time, the elastically set insert (47) is inserted into the socket (46) to limit and fix the top cover plate (39); The gas inside the sleeve (8) lifts the cover plate (39), and the gas is discharged into the tube (10) through the vent plate (38) and lifts the push plate (36). When the upper mold (1) is lifted to remove the mold, the tube (10) is lifted from the inside of the sleeve (8). When the tube (10) is completely lifted out of the inside of the sleeve (8), the extrusion block (42) pops out and the insertion block (47) moves out from the inside of the insertion port (46). At this time, the third reset spring (35) pushes the push plate (36) to reset. When resetting, the gas inside the tube (10) is discharged to the upper vent plate (38) through the fourth exhaust pipe (37). With the cooperation of the upper vent plate (38), it is discharged into the upper mold (1) and blows out the coolant in the cooling channel of the upper mold (1).
