Description
Technical Field
[0001] This invention relates to the field of sanitary ceramics production equipment technology, and in particular to a high-pressure injection molding equipment and molding method for simultaneous high-pressure injection molding of toilet tanks and toilet seats. Background Technology
[0002] The toilet tank and toilet body synchronous high-pressure injection molding equipment is an automated production equipment used in the sanitary ceramics industry for the integrated and synchronous molding of one-piece toilets. The core technology is to inject ceramic slurry into the integrated mold of the water tank and toilet body under high pressure, quickly dehydrate and form, and directly produce a complete ceramic blank of the one-piece toilet, replacing the outdated process of traditional separate injection and bonding.
[0003] Traditional high-pressure injection molding equipment for toilet tanks and toilet seats cannot immediately remove the burrs at the connection between the tank and the seat, or at the sides of the blank, after the blank is ejected. The ejected blank must first be sent to a specialized trimming station for subsequent trimming. This transfer process takes a lot of time. When the ceramic blank is removed from the mold and exposed to air, it will quickly lose water and harden. By the time the blank is transferred to the trimming station, its hardness has increased significantly, and the burrs at the mold joint have also hardened and solidified. When workers perform manual trimming, the operation becomes much more difficult, and the hardened burrs are difficult to smooth with conventional tools, which easily leads to incomplete trimming and poor trimming accuracy.
[0004] Therefore, it is necessary to provide equipment and methods for simultaneous high-pressure injection molding of toilet tanks and toilet seats to solve the above-mentioned technical problems. Summary of the Invention

[0015] To address the above problems, the present invention also provides a molding method for simultaneous high-pressure injection molding of the toilet tank and the toilet seat body, comprising the following steps: T1: The combined mold for the toilet tank and the toilet body is closed and locked to ensure that the mold cavity is sealed and the positioning is accurate; T2: Introduce compressed air into the mold cavity to blow away and remove residual cleaning water and impurities inside the mold; T3: Start the grouting system and perform multi-stage low-pressure grouting into the mold cavity, so that the grout slowly fills the cavity and expels the internal air, initially forming the outline of the blank; T4: Compressed air is introduced into the inner cavity of the preform to push the uncured excess slurry out from the slurry outlet, thus initially clearing the slurry inside the cavity; T5: After the blank reaches the set curing strength, release the mold lock and control the mold opening to push out the formed toilet tank and toilet body as a single blank. T6: Start the transfer assembly to move the toilet tank and toilet body out of the injection molding equipment until the blank is moved to the working area of the mold seam trimming device; T7: Activate the mold seam trimming device to remove the burrs at the connection between the water tank and the toilet body. After completion, the staff will remove the water tank and the toilet body.
[0016] Compared with related technologies, the toilet tank and toilet seat body synchronous high-pressure injection molding equipment and molding method provided by the present invention have the following beneficial effects: This invention provides a high-pressure injection molding equipment for toilet tanks and toilet bodies. Through the cooperation of a transfer component, a joint trimming mechanism, and a side scraping mechanism, the injection molding, transfer, and mold seam trimming processes of the toilet body can be completed on the same equipment without the need for additional blank transfer. This effectively simplifies the production process and avoids the problem of the blank hardening due to prolonged transfer to a designated position for edge trimming, making it difficult to trim the mold seam. The coordinated arrangement of components such as the transfer plate, rollers, sprockets, and chains can stably receive and transport the toilet body blank ejected from the injection molding equipment, preventing the blank from being bumped, tilted, or deformed during the transfer process. The combined setup of the joint trimming mechanism and the side scraping mechanism enables automated removal of burrs from the joint between the toilet tank and the toilet body, as well as from the side mold seams. The centering seat automatically centers and positions the blank, and with the reciprocating screw, grinding wheel, and belt, it can efficiently grind and flexibly scrape the joint mold seams. The vibration motor, U-shaped sliding plate, and first scraper allow the first scraper to elastically fit against the side of the blank and vibrate at high frequency to scrape away the burrs more thoroughly. At the same time, the U-shaped dust collection box can collect dust and debris generated during the trimming process in real time, preventing debris from scattering and contaminating the blank and equipment. By coordinating the edge-removing mechanism and its internal components, the rough edges of the mold seam at the drain outlet of the toilet blank can be trimmed. The coordinated arrangement of the second cylinder, support plate, sliding cylinder, and top cylinder allows the edge-removing mechanism to smoothly rise and fall and be fitted onto the outside of the drain outlet. The second inclined surface on the top cylinder provides guiding connection, and the sliding cylinder allows for slight positional adjustments, adapting to blanks with positional deviations in the drain outlet and improving the device's adaptability and flexibility. Furthermore, the transmission arrangement of the sixth motor, second gear, third gear, ring plate, and second scraper drives the second scraper to rotate uniformly along the inner wall of the drain outlet. Combined with the elastic pressing action of the third guide rod and the sixth spring, the second scraper remains tightly pressed against the inner wall of the drain outlet, achieving uniform and complete scraping of the rough edges. This solves the problem of workers needing to use other tools to lift and trim the toilet blank when cleaning the rough edges inside the drain outlet.
[0017] This invention provides a high-pressure injection molding equipment and method for simultaneous high-pressure injection molding of toilet tank and toilet body. The molding method uses the aforementioned high-pressure injection molding equipment for simultaneous high-pressure injection molding of toilet tank and toilet body, and can immediately complete the transfer and multi-process edge trimming in place after injection molding, simplifying the production process and significantly improving the overall production efficiency.

[0021] First embodiment: Please refer to the following: Figures 1-11 In the first embodiment of the present invention, the toilet tank and toilet body synchronous high-pressure injection molding equipment includes: a frame 1 and an injection molding device 2. The injection molding device 2 is set on the top of the frame 1. Two bases 3 are fixedly installed on the top of the frame 1. One of the bases 3 is provided with a transfer component.

After the toilet blank is formed, it is ejected by the grouting molding equipment 2. At this time, the first motor 10 is started, which drives the first gear 11 to rotate. Through the meshing transmission with the toothed plate 7, the U-shaped transfer plate 5 is driven to slide towards the grouting molding equipment 2 until the roller 4 receives the formed toilet blank. Then, the second motor 12 is started, which drives the rotating rod to rotate. Through the transmission of the sprocket 13 and the chain 14, all rollers and roller 4 rotate synchronously, which smoothly moves the toilet blank from inside the grouting molding equipment 2 to the outside. At the same time, the first motor 10 drives the first gear 11 to reverse, which moves the U-shaped transfer plate 5 away from the grouting molding equipment 2 until the blank moves to the working area of the mold seam trimming device. This can realize the smooth reception and transportation of the toilet blank ejected from the grouting molding equipment 2, and avoid the blank from being bumped, tilted or deformed during the transfer process.
[0023] The joint trimming mechanism includes a centering seat 16, a U-shaped frame 18, a movable plate 9, and a suspension arm 24. A mounting frame 6 is fixedly installed on the top of the base 3. The U-shaped frame 18 is slidably installed inside the mounting frame 6. Fixed ears are integrally formed on both outer walls of the U-shaped frame 18, extending beyond the mounting frame 6.

The suspension arm 24 is threadedly connected to... The reciprocating screw 20 is located on the outside, and the suspension arm 24 is slidably connected to the guide rail. A fifth motor 27 is fixedly installed on the top of the suspension arm 24. The output shaft of the fifth motor 27 extends to the bottom of the suspension arm 24 and a grinding wheel 26 is fixedly installed thereon. Multiple rotating wheels 23 are rotatably installed inside the suspension arm 24. Two belts 25 are fitted on the outside of each of the multiple rotating wheels 23. Inclined elastic plates are fixedly installed on the outer walls of the two belts 25. Two fourth motors 22 are fixedly installed on the top of the suspension arm 24. The output shafts of the two fourth motors 22 are fixedly connected to two of the rotating wheels 23 respectively. When the first cylinders 8 on both sides are activated, the telescopic ends of the first cylinders 8 drive the U-shaped frame 18 to slide downward along the mounting frame 6. At this time, the centering seat 16 guides the blank to automatically center through the first inclined surface of the inner wall. Then, the U-shaped frame 18 continues to descend, bringing the bottom of the movable plate 9 into contact with the connection surface between the water tank and the toilet body. The U-shaped dust collection box 19 fits against the outer side of the toilet body. Then, the first cylinder 8 is closed, and the third motor 21, the fifth motor 27, and the two fourth motors 22 are started in sequence. The third motor 21 drives the reciprocating screw 20 to rotate, causing the suspension arm 24 to move horizontally back and forth along the guide rail. The output shaft of the fifth motor 27 drives the grinding wheel 26 to rotate at high speed, grinding away the burrs at the joint between the toilet tank and the toilet body. The two fourth motors 22 drive the rotating wheel 23 and the belt 25 to rotate.

The vibration motor 30 is fixedly mounted on the top of the U-shaped sliding plate 29. Multiple second grooves are provided at the bottom of the U-shaped sliding plate 29, and second fixing rods are fixedly installed in each of these second grooves. The multiple first scrapers 28 are slidably mounted on the multiple second fixing rods, and a fourth spring is sleeved on the outer side of each of the multiple second fixing rods. The two ends of the fourth springs are fixedly connected to the second grooves and the first scrapers 28, respectively. Under the action of the fourth springs, the multiple first scrapers 28 can always elastically conform to the side mold seam of the blank. Then, the vibration motor 30 is started, driving the U-shaped sliding plate 29 to vibrate at high frequency along the first fixing rods, shaking off and scraping away the side burrs.
[0025] In this embodiment: After the toilet blank is formed, it is ejected by the grouting molding equipment 2. At this time, the first motor 10 is started. The first motor 10 drives the first gear 11 to rotate.

Then the second motor 12 is started. The second motor 12 drives the rotating rod to rotate. Through the transmission of the sprocket 13 and the chain 14, all the rollers and the roller 4 rotate synchronously, and the toilet blank is smoothly transferred from inside the grouting molding equipment 2 to the outside. At the same time, the first motor 10 drives the first gear 11 to reverse, and drives the U-shaped transfer plate 5 away from the grouting molding equipment 2 until the blank moves to the working area of the mold seam trimming device. After the blank is in place, the first motor 10 and the second motor 12 are turned off, and the transfer assembly remains stationary. The first cylinders 8 on both sides are activated. The telescopic end of the first cylinder 8 drives the U-shaped frame 18 to slide down along the mounting frame 6. At this time, the centering seat 16 guides the blank to automatically center through the first inclined surface of the inner wall. Then the U-shaped frame 18 continues to descend, so that the bottom end of the movable plate 9 contacts the connection surface between the water tank and the toilet body. The U-shaped dust collection box 19 is attached to the outside of the toilet body blank. Then the first cylinder 8 is closed, and the third motor 21, the fifth motor 27 and the two fourth motors 22 are activated in sequence. The third motor 21 drives the reciprocating screw 20 to rotate, which drives the suspension arm 24 to move horizontally back and forth along the guide rail. The output shaft of the fifth motor 27 drives the grinding wheel 26 to rotate at high speed to grind and remove the burrs at the mold seam where the toilet water tank and the toilet body are connected. The two fourth motors 22 drive the rotating wheel 23 and the belt 25 to rotate. The inclined elastic plate moves in a cycle with the belt 25 to flexibly scrape off the residual burrs and debris at the connection. The dust and debris generated during the finishing process are scraped into the U-shaped dust collection box 19 below for collection. When the U-shaped dust collection box 19 is attached to the outside of the toilet blank, the multiple first scrapers 28 at the bottom of the U-shaped sliding plate 29 are always elastically attached to the side mold seam of the blank under the action of the fourth spring. At this time, the vibration motor 30 is started. The vibration motor 30 drives the U-shaped sliding plate 29 to vibrate at high frequency along the first fixed rod, which shakes off and scrapes off the side burrs. After the scraping is completed, the vibration motor 30 is turned off and the side scraping mechanism is reset, completing the edge removal work of the toilet blank.

[0029] In this embodiment: When the toilet blank is moved to the upper part of the base cavity 3, the two second cylinders 36 in the cavity are activated. The two second cylinders 36 push the support plate 31 upward through the telescopic end, which drives the edge removal mechanism to rise as a whole. The top cylinder 34 and the sliding cylinder 37 are guided by the second inclined surface to be sleeved on the outside of the drain port. When the position of the drain port is deviated, the sliding cylinder 37 moves slightly in the movable cavity through the limit plate. Then the sixth motor 32 is activated. The output shaft of the sixth motor 32 drives the second gear 33 to rotate. Through meshing with the third gear 39, the annular plate 41 is driven to rotate at a constant speed on the inner wall of the top cylinder 34. Under the action of the sixth spring and the third guide rod 40, the four second scrapers 42 always stick to the inner wall of the drain port. With the rotation of the annular plate 41, the rough edges of the inner wall mold seam are completely scraped off. The scraped rough edges and debris fall into the bottom dust collection box 35 through the top cylinder 34, the sliding cylinder 37 and the chip discharge port for collection, so as to avoid the debris from scattering and contaminating the equipment and the blank. After the edge removal of the sewage outlet is completed, the sixth motor 32 is turned off, the second cylinder 36 is controlled to retract, and the support plate 31 and the edge removal mechanism are driven to descend and reset, thus completing the edge removal work of the sewage outlet.
[0030] Third embodiment: This embodiment provides a molding method for simultaneous high-pressure injection molding of a toilet tank and a toilet seat, including the following steps: T1: The combined mold for the toilet tank and the toilet body is closed and locked to ensure that the mold cavity is sealed and the positioning is accurate; T2: Introduce compressed air into the mold cavity to blow away and remove residual cleaning water and impurities inside the mold; T3: Start the grouting system and perform multi-stage low-pressure grouting into the mold cavity, so that the grout slowly fills the cavity and expels the internal air, initially forming the outline of the blank; T4: Compressed air is introduced into the inner cavity of the preform to push the uncured excess slurry out from the slurry outlet, thus initially clearing the slurry inside the cavity; T5: After the blank reaches the set curing strength, release the mold lock and control the mold opening to push out the formed toilet tank and toilet body as a single blank. T6: Start the transfer assembly to move the toilet tank and toilet body out of the injection molding equipment 2, until the blank is moved to the working area of the mold seam trimming device; T7: Activate the mold seam trimming device to remove the burrs at the connection between the water tank and the toilet body. After completion, the staff will remove the water tank and the toilet body.
