Description

Technical Field

[0001] The present application relates to the field of sanitary ceramic molding technology, and in particular to a high-pressure molding machine for producing high-pressure molded sanitary ceramics. Background Art

[0002] Sanitary ceramics, as indispensable glazed ceramic products in bathrooms, kitchens, laboratories and other places, play an important role in the fields of architecture and home furnishing. Its production process is complex and has high requirements for molding quality. High-pressure molding technology has gradually been widely used in the production of sanitary ceramics because it can make the green body dense and uniform, and improve product strength and quality.

[0003] Existing sanitary ceramic high-pressure forming machines are usually composed of mechanical structures, hydraulic systems, electrical control systems, etc., and ceramic slurry is injected into the mold cavity under high pressure to form the blank. Taking the sanitary ceramic squat toilet high-pressure forming machine as an example, it includes columns, beams, side opening and closing cylinders, linear sliding modules, left baseboard units, right baseboard units and other parts. Among them, the columns are used to support the entire equipment to ensure its stability; the side opening and closing cylinders and other components are installed on the beams; the side opening and closing cylinders can realize the opening and closing of the mold; the linear sliding module helps the linear movement of related components to cooperate to realize various operations.

[0004] However, after the high-pressure forming of the workpiece is completed, the work of removing the workpiece faces many difficulties. On the one hand, the structural design of the equipment itself brings many inconveniences to the removal. Its forming mold is often located in a specific position inside the equipment, surrounded by other components or frames, resulting in an extremely narrow space for taking out the workpiece. On the other hand, the characteristics of the sanitary ceramic body itself also increase the difficulty of taking out the workpiece. Although the body after high-pressure forming has a certain strength, it is still relatively fragile. During the process of taking out the workpiece, any improper operation, such as uneven force, slight collision, etc., may cause defects such as cracks and missing corners in the body, seriously affecting the product quality.

[0005] The manual connection of blanks is very labor-intensive for workers because the blanks are usually heavy and located at a high position. Relevant practitioners have also tried to develop and design some blank removal robots or devices. However, such equipment is expensive, difficult to maintain, and its stability is also under great scrutiny. It still cannot fundamentally and effectively solve the problem of inconvenient removal of sanitary ceramic high-pressure forming machines. Therefore, there is an urgent need for a more optimized, efficient and reliable solution to promote technological innovation and development progress in the removal link of the sanitary ceramic production industry. Summary of the invention

[0006] In order to solve the technical problems raised in the background technology, the present application provides a high-pressure molding machine for producing high-pressure molding sanitary ceramics.

[0007] The high pressure forming machine for high pressure forming sanitary ceramic production provided in the present application adopts the following technical solution: A high pressure forming machine for producing high pressure forming sanitary ceramics, comprising: Suspension; The two side molds are connected to the bottom of the suspension frame for relative motion, and a mold cavity with an open bottom is formed between the two side molds; A bottom mold is horizontally arranged between the two side molds, and when the two side molds are in a mold closing state, the bottom mold closes the bottom of the mold cavity; Two sets of side shafts are symmetrically arranged on both sides of the bottom mold, and the axes are arranged along the mold closing direction. One end of the side shaft is movably arranged on the bottom mold and is formed with a limiting piece to limit the side shaft from being separated from the base. The other end of the side shaft is movably inserted into the side mold on the same side to maintain the bottom mold in the mold opening state. A first elastic member is disposed on the bottom mold and is used to push the outer end of the side shaft to remain inserted into the side mold; The slide seat is movably arranged on the lower side of the bottom mold in a direction perpendicular to the mold closing direction and can abut against the lower bottom surface of the bottom mold. The upper side of the slide seat is formed with two guide rails with the front ends in an outward-O-shaped shape along its movement direction; The movement of the slide seat can cause the two guide rails to push the limiting parts of the two sets of side shafts to move in relative directions, so that the outer ends of the side shafts are separated from the side molds, and then the bottom mold can slide synchronously to move to separate from between the two side molds.

[0008] By adopting the above technical scheme, after the forming of the workpiece is completed, the two side molds are opened. At this time, the outer ends of the two sets of side shafts are inserted into the side molds, which can play a role in supporting the bottom mold and the workpiece on the bottom mold. Then, by moving the slide, with the help of the cooperation of the guide rails and the side shaft limiting parts, the guide rails will gradually push the side shafts out of the side molds, thereby releasing the restriction of the bottom mold, allowing the bottom mold to drive the formed workpiece to move out from between the two side molds with the slide, effectively solving the problem of narrow space for taking out due to the equipment structure, making it convenient to take out the formed sanitary ceramic blanks, and the structure is relatively simple, which reduces the difficulty and cost of taking out, and reduces the possibility of damage to the blanks due to the taking out operation.

[0009] Optionally, the limiting member is a cylindrical cam, the end of the side shaft is fixed to the circumferential surface of the cylindrical cam, and the rotation of the cylindrical cam can drive the side shaft to rotate, and further includes: Two push rods are fixed to the slide seat along the movement direction of the slide seat, and push terminals are fixed on the push rods; After the slide moves to the straight section where the limiting member contacts the guide rail, the slide continues to move to drive the push terminal to insert into the curved groove of the cylindrical cam, thereby driving the cylindrical cam to rotate, so that the side shaft rotates upward to contact the two sides of the upper blank of the bottom mold.

[0010] By adopting the above technical solution, when the slide moves, the push terminal on the push rod cooperates with the cylindrical cam, which will drive the side shaft to rotate and contact the two sides of the embryo body on the bottom mold. During the removal process, it can provide certain support and protection for the embryo body, preventing the embryo body from being displaced or damaged due to its own gravity or other external forces, further improving the safety and reliability of removal and ensuring the integrity of the sanitary ceramic body.

[0011] Optionally, also include: A slider slides in the bottom mold along the mold closing direction and is arranged corresponding to the cylindrical cam. One end of the elastic member is fixed to the bottom mold and the other end is fixed to the slider. Two plug posts are formed on one side of the slide seat facing the cylindrical cam and arranged in the vertical direction. The end of the cylindrical cam is formed with a concentric annular groove. The two plug posts are inserted at the upper and lower sides of the concentric annular groove. The cylindrical cam can rotate in situ relative to the two plug posts. The slide block drives the two plug posts to slide, and can drag the cylindrical cam to move synchronously.

[0012] By adopting the above technical solution, the slider drives the plug column to move, thereby dragging the cylindrical cam to move synchronously, realizing precise control of the position of the cylindrical cam, making the movement of the side shaft more stable and orderly, and ensuring the accuracy of the operation of the bottom mold and the embryo during the removal process, which helps to improve the work efficiency and stability of the entire high-pressure forming machine removal link and reduce the risk of failure caused by uncoordinated movement of components.

[0013] Optionally, also include: A second elastic member is disposed in the annular groove, and one end of the second elastic member is fixed to any plug post in the annular groove; A baffle plate is fixedly formed in the annular groove, and the other end of the second elastic member is fixed to the baffle plate; The second elastic member pushes the baffle to drive the cylindrical cam to rotate, so that the side shaft can rotate from a vertical state to a horizontal state.

[0014] By adopting the above technical solution, the second elastic member drives the cylindrical cam to rotate by pushing the baffle, so as to keep the side shaft in a horizontal state under normal conditions. This elastic driving method can buffer the rotation of the side shaft to a certain extent, reduce the impact force during the rotation of the side shaft, and avoid damage to the bottom mold or the embryo due to excessive movement of the side shaft. It can also realize the switching of the side shaft state without the need for an external complex driving mechanism, thereby simplifying the equipment structure and reducing costs.

[0015] Optionally, a bearing column rotatably plugged into the cylindrical cam is fixed to the sliding block at a position corresponding to the axis of the cylindrical cam.

[0016] By adopting the above technical solution, the setting of the bearing column enhances the connection stability between the slider and the cylindrical cam, improves the bearing capacity of the cam, and enables the cylindrical cam to rotate more smoothly when the slider drags the cylindrical cam to move, thereby reducing the shaking or deviation of the cylindrical cam caused by unstable connection, ensuring effective support and protection of the bottom mold and the blank during the removal operation, and further improving the reliability of the equipment operation.

[0017] Optionally, the guide column is arranged along the mold closing direction, with both ends inserted between the two side molds, and the middle part is fixed to the suspension, and is located at the bottom of the two side molds; A positioning block is formed on one side of the guide column facing the bottom mold, and can be plugged into the rear side of the bottom mold to limit the movement of the bottom mold along the mold closing direction.

[0018] By adopting the above technical scheme, the setting of the guide column limits the position of the bottom mold. During the mold closing and opening process, it ensures that the bottom mold can move accurately at the predetermined position, prevents the bottom mold from shifting or shaking, improves the overall stability of the mold, and thus ensures the molding quality of the sanitary ceramic blank. At the same time, it also helps the coordinated movement of the bottom mold and the slide seat when removing the parts, making the removal operation smoother.

[0019] Optionally, two stripper plates are symmetrically arranged on the opposite sides of the two side molds, and each stripper plate is fixed with a stripper rod whose end passes through the side mold and extends to the mold cavity; As the two side molds are separated, the demoulding rod can push the embryo body in the mold cavity to separate from the side molds.

[0020] By adopting the above technical solution, when the two side molds are separated, the demolding rod on the demolding plate can automatically push the embryo body in the mold cavity to separate from the side mold, ensuring that the embryo body is located on the upper side of the bottom mold, reducing manual intervention, reducing the labor intensity of workers, and improving the degree of automation of taking out parts. In addition, the function of the demolding rod makes the separation process of the embryo body and the side mold more uniform and stable, avoiding damage to the embryo body due to local uneven force, and ensuring product quality.

[0021] Optionally, the two stripping plates are movably connected to the suspension along the mold closing direction.

[0022] By adopting the above technical solution, when the two side molds are separated, the demoulding plate moves, which can drive the demoulding rod to separate from the embryo on the bottom mold, making the separation process of the embryo and the side mold more uniform and stable, avoiding damage to the embryo due to local uneven force, and ensuring product quality.

[0023] Optionally, the outer ends of the side shafts can pass through the side molds, and the peripheral walls of the side shafts are vertically provided with lock holes, and further include: The locking cylinder is vertically fixed to the away-from sides of the two side molds, and the telescopic rod of the locking cylinder is extended to vertically pass through the locking hole of the peripheral wall of the side shaft.

[0024] By adopting the above technical scheme, the locking cylinder cooperates with the locking hole on the side shaft, and the side shaft can be locked during the mold closing process, further ensuring the sealing and stability of the two side molds and the bottom mold in the mold closing state, ensuring the molding quality of the blank, and when taking out the parts, the unlocking operation of the locking cylinder can enable the side shaft to carry out subsequent movements smoothly, thereby improving the controllability and safety of the equipment operation.

[0025] Optionally, floating steel balls are provided on the surface of the slide seat.

[0026] By adopting the above technical solution, the floating steel balls on the surface of the slide seat reduce the friction between the slide seat and the bottom surface of the bottom mold, making the movement of the slide seat smoother, reducing energy loss, and improving the response speed and accuracy of the slide seat movement, which is beneficial to the efficient performance of the entire retrieval operation. At the same time, it also reduces the wear caused by friction and extends the service life of the slide seat and related components.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The problem of narrow space for taking out sanitary ceramic high pressure forming machines is effectively solved through the coordinated design of the slide, side shaft, bottom mold and other components. The cooperation between the slide and the side shaft limiter enables the convenient removal of the bottom mold, reduces the difficulty of taking out due to the equipment structure, and avoids the risk of damage to the fragile blank due to limited operating space during the taking out process. At the same time, compared with complex and expensive devices such as blank taking robots, this structure is simple and low in cost, providing an effective solution for the taking out link of sanitary ceramic production.

[0028] 2. Through the combination of cylindrical cam, push rod, slider, plug column and other components, the side shaft movement is precisely controlled. When picking up parts, the side shaft can be flexibly rotated according to the process requirements and stably support the embryo on the bottom mold, effectively preventing the embryo from being displaced or damaged due to gravity or external force, and improving the safety and reliability of picking up parts.

[0029] 3. The setting of the guide column ensures the position accuracy of the bottom mold during the mold closing and opening process, enhances the overall stability of the mold, guarantees the molding quality of the blank, and is conducive to the coordination between the bottom mold and the slide when removing the parts; the design of the demoulding plate and the demoulding rod improves the degree of automation of removing parts, reduces manual intervention and labor intensity, and can separate the blank and the side mold evenly and stably, avoiding damage caused by local uneven force; the locking function of the locking cylinder on the side shaft enhances the stability and controllability of the mold working state, and ensures the smooth progress of the production process; the floating steel balls on the surface of the slide optimize the movement performance of the slide, reduce friction loss, improve response speed and accuracy, promote efficient removal operations and extend the service life of components.

[0033] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0034] The inventor of the present application found that after the high-pressure forming machine of sanitary ceramics completes the high-pressure forming of the workpiece, the work of taking out the workpiece faces many difficulties, such as the inconvenience of taking out the workpiece caused by the equipment structure design and the fragility of the characteristics of the sanitary ceramic blank itself. To this end, the present application mainly adopts the following high-pressure forming machine, including a suspension, two side molds, a bottom mold, two sets of side shafts, elastic parts, a slide seat and related components, which achieves the effect of simplifying the process of taking out the workpiece, improving the efficiency of taking out the workpiece and reducing the damage to the blank. The present application is further described in detail below. Example

[0035] Reference Figure 1-2 A high-pressure forming machine for high-pressure forming sanitary ceramic production includes a suspension 1, a forming mold 2 is arranged on the suspension 1, and a material taking vehicle is arranged below the forming mold 2. The suspension 1 is used to carry the forming mold 2, the forming mold 2 is used to form a ceramic embryo, and the material taking vehicle is used to take out the ceramic embryo after the forming mold 2 is opened.

[0036] Specifically, the suspension 1 is a door-type frame, including two vertical frames 11 and a horizontal frame 12 horizontally fixed between the two vertical frames 11. The molding mold 2 includes two side molds 21, and a molding cavity between the two side molds 21 is used to mold a ceramic embryo. The upper ends of the two side molds 21 slide on the horizontal frame 12 along the length direction of the horizontal frame 12, and the first pair of screw rods 13 are rotatably connected to the horizontal frame 12 along its length direction. The two side molds 21 are respectively threadedly connected to the two threaded sections of the first pair of screw rods 13, and the first servo motor 131 for driving the first pair of screw rods 13 to rotate is also fixed on the horizontal frame 12. During operation, the first servo motor 131 drives the first pair of screw rods 13 to rotate forward and reverse, which can push the two side molds 21 to move relative or away from each other, thereby realizing the closing or opening of the two side molds 21.

[0037] A guide post 14 is provided between the two side molds 21 along the mold closing direction. The guide post 14 is located at the lower rear part of the two side molds 21. Both ends of the guide post 14 pass through and slide on the two side molds 21. Two connecting frames 121 are vertically fixed below the cross frame 12. Both ends of the guide post 14 pass through the side molds 21 and are respectively fixed to the two connecting frames 121. The provision of the guide post 14 can further improve the stability of the two side molds 21 during mold opening and mold closing.

[0038] It should be noted that, compared with the conventional molding die 2, the present molding die 2 further includes a bottom die 22. In the present solution, the mold cavity formed after the two side molds 21 are molded together is open at the bottom, and the bottom die 22 is located at the lower position between the two side molds 21, and is used to cooperate with the two side molds 21. That is, in the mold-closing state, the lower part of the mold cavity formed by the two side molds 21 is closed by the bottom die 22 to form a complete mold cavity for the molding die 2.

[0039] The connection method between the bottom mold 22 and the side mold 21 is described in detail below.

[0040] Reference Figure 3-4Two groups of side shafts 4 are symmetrically arranged on both sides of the bottom mold 22, and each group of side shafts 4 includes multiple side shafts 4 arranged perpendicular to the mold closing direction, and the axial direction of each side shaft 4 is arranged along the mold closing direction. One end of each side shaft 4 is inserted into the bottom mold 22 and is formed with a limiting member to limit the end of the side shaft 4 from being separated from the bottom mold 22, and the other end of each side shaft 4 is slidably inserted into the side mold 21. In this way, in the mold closing state, the two ends of the side shaft 4 are located between the bottom mold 22 and the side mold 21, which not only ensures the close connection between the side mold 21 and the bottom mold 22, but also realizes the acceptance of the bottom mold 22. In the mold opening state, the setting of multiple side shafts 4 can also connect the side mold 21 and the bottom mold 22, and accept the bottom mold 22.

[0041] Furthermore, the guide column 14 can contact the rear part of the bottom mold 22, and a positioning column (not shown in the figure) is fixed to the guide column 14 in the direction toward the bottom mold 22. The bottom mold 22 is formed with a positioning hole corresponding to the position of the positioning column, and the positioning column can be inserted into the positioning hole. On the one hand, the bottom mold 22 is limited to the middle position of the molding mold 2, and will not move along the mold closing direction with the opening and closing of the side mold 21, and the rear position of the bottom mold 22 is limited to constrain the position of the bottom mold 22. On the other hand, the positioning column is inserted into the positioning hole, which can also play an auxiliary bearing role for the bottom mold 22.

[0042] Replay Figure 1-2 , a stripper plate 15 is vertically arranged on the side away from the two side molds 21, and the upper end of the stripper plate 15 is also slidably connected to the horizontal frame 12, and a second pair of thread screws 16 are rotatably connected to the horizontal frame 12 along its length direction, and the two stripper plates 15 are respectively threadedly connected to the two threaded sections of the second pair of thread screws 16, and a second servo motor 161 for driving the second pair of thread screws 16 to rotate is also fixed to the horizontal frame 12. During operation, the second servo motor 161 drives the second pair of thread screws 16 to rotate forward and reversely, so as to push the two stripper plates 15 to move relative to or away from each other, thereby adjusting the relative positions of the two stripper plates 15. A plurality of demoulding rods 151 are fixed to opposite sides of the two demoulding plates 15, and each demoulding rod 151 passes through the side mold 21 on the same side and extends to the mold cavity wall. When the mold is opened, the demoulding rods 151 can make the formed embryo separate from the side mold 21 and be located on the bottom mold 22. After the overall demoulding of the side mold 21 is completed, the positions of the plurality of demoulding rods 151 are adjusted by the demoulding plates 15, so that the demoulding rods 151 and the embryo are completely separated, and only the embryo is retained on the upper side of the bottom mold 22.

[0043] Reference Figure 4-5Furthermore, one end of each side shaft 4 inserted in the bottom mold 22 slides on the bottom mold 22, and a slide groove 221 is formed in the bottom mold 22 along the mold closing direction on both sides corresponding to each side shaft 4, and a slider 23 slides in the slide groove 221. The limiting member is a cylindrical cam 5 whose axis direction is perpendicular to the side shaft 4, and the diameter of the cylindrical cam 5 is larger than the diameter of the side shaft 4. The side shaft 4 is fixed to the circumference of the cylindrical cam 5. A bearing column 231 is fixed between the two sliders 23 of the cylindrical cam 5 at the position corresponding to the axis of the cylindrical cam 5. The bearing column 231 passes through the cylindrical cam 5 and can rotate relative to the cam. The movement of the slider 23 can drag the cylindrical cam 5 to move synchronously.

[0044] A first elastic member 24 such as a spring is also fixed in the slide groove 221. The first elastic member 24 pushes the slider 23 to move, so that the slider 23 can be located at one end of the slide groove 221 close to the side mold 21, and then the cylindrical cam 5 can be pushed to move until the side shafts 4 on both sides of the slide seat 3 are located at the extreme positions of opposite movement, that is, the length of the side shaft 4 extending out of the base reaches the limit length. In this state, no matter whether the side wall mold is opened or closed, the end of the side shaft 4 is inserted into the side mold 21 to maintain support for the bottom mold 22.

[0045] The material picking trolley is arranged below the forming mold 2 and reciprocates perpendicularly to the mold closing direction. Specifically, a track can be laid in advance, and the material picking trolley is equipped with track wheels that match the track. The movement of the material picking trolley can be achieved by driving the track wheels through a driving cylinder or by driving a stepper motor.

[0046] Reference Figure 2-3 A slide 3 is fixed on the material reclaiming vehicle, and the slide 3 moves with the material reclaiming vehicle, and can move from the rear of the forming mold 2 to the front of the forming mold 2. A plurality of floating steel balls are installed on the upper side of the slide 3, and as the slide 3 moves, the floating steel balls can contact the lower side of the bottom mold 22, thereby reducing the friction between the bottom mold 22 and the slide 3.

[0047] Two guide rails 31 are fixed on the upper surface of the slide 3 along its movement direction. The two guide rails 31 are symmetrically arranged on both sides of the slide 3, and the front ends of the two guide rails 31 are arranged in an outward eight shape, so that each guide rail 31 includes an oblique line segment and a straight line segment. A groove 25 is formed at the position corresponding to the guide rail 31 on the lower side of the bottom mold 22. When the slide 3 moves to the lower side of the bottom mold 22, the oblique line segments of the two guide rails 31 will first be inserted into the groove 25, and then with the movement of the slide 3, the oblique line segments of the guide rails 31 will contact the circumferential wall of the cylindrical cam 5 at the end of the side shaft 4 on both sides of the base, and then gradually push each cylindrical cam 5 to move toward the middle of the bottom mold 22, driving the side shaft 4 to retract, until the straight line segment of the guide rail 31 contacts each cylindrical cam 5, each side shaft 4 retracts to the limit position, and one end of the side shaft 4 inserted in the side mold 21 is also pulled out of the side mold 21. When the slide 3 is completely moved to the bottom of the bottom mold 22, the bottom mold 22 is supported, and all the side shafts 4 are also completely pulled out from the side molds 21. At this time, the slide 3 continues to move, which can drive the bottom mold 22 carrying the embryo to move out from between the two side molds 21, and then the staff can easily remove the formed embryo from the bottom mold 22.

[0048] After the embryo is removed from the upper side of the bottom mold 22, the slide 3 moves in the opposite direction, driving the bottom mold 22 back between the two side molds 21, and the bottom mold 22 will first be plugged into the positioning column to limit the position of the bottom mold 22, and then the slide 3 continues to move, so that the guide rail 31 gradually withdraws from the groove 25 of the bottom mold 22, and the first elastic member 24 works to push each cylindrical cam 5 to move, so that the other end of each side shaft 4 is inserted into the corresponding side mold 21. Until the guide rail 31 is completely out of the groove 25, the bottom mold 22 is also reassembled between the two side molds 21, and the mold closing operation can be performed again.

[0049] Reference Figure 5-7 Furthermore, both ends of the cylindrical cam 5 are formed with an annular groove 51 which is coaxial with the cylindrical cam 5, and the slider 23 is fixed with two vertically arranged plug posts 232 on the side facing the cylindrical cam 5, and the two plug posts 232 are simultaneously inserted into the upper and lower parts of the cam annular groove 51, so that the cylindrical cam 5 can rotate in situ relative to the slider 23, and the movement of the slider 23 can drag the cylindrical cam 5 to move synchronously.

[0050] A baffle plate 52 is also fixed in the annular groove 51. A second elastic member 53 such as a push spring is also fixed in the annular groove 51. One end of the second elastic member 53 is fixed to the baffle plate 52, and the other end is fixed to a plug column 232. The second elastic member 53 pushes the baffle plate 52 to drive the cylindrical cam 5 to rotate, so that the side shaft 4 can be rotated from a vertical state to a horizontal state.

[0051] Two push rods 32 are symmetrically formed between the two guide rails 31 on the upper side of the slide 3. A plurality of push terminals 33 corresponding to the cylindrical cam 5 are fixed on the opposite sides of the two push rods 32. After the slide 3 moves to the straight section of the guide rail 31 and contacts the cylindrical cam 5, the slide 3 continues to move and drives the push terminals 33 to insert into the curved groove 25 of the cylindrical cam 5, so as to drive the cylindrical cam 5 to rotate, thereby causing the side shaft 4 to rotate upward and contact the two sides of the embryo on the bottom mold 22. Then, when the slide 3 drives the bottom mold 22 to separate from between the two side molds 21, the embryo is protected. Similarly, when the slide 3 drives the bottom mold 22 to return, the push terminals 33 will also first separate from the cylindrical cams 5. At this time, the second elastic member 53 works to drive the side shafts 4 to maintain a horizontal state, so that the subsequent side shafts 4 can be inserted into the side mold 21.

[0052] Reference Figure 4 Furthermore, in other embodiments of the present application, the outer ends of the side shafts 4 can pass through the side molds 21, and the side walls of the side shafts 4 are vertically provided with locking holes 41. The sides of the side molds 21 facing away from each other are also vertically fixed with locking cylinders 211, and the telescopic rods of the locking cylinders 211 extend and can vertically pass through the locking holes 41 of the side wall of the side shafts 4. The locking cylinders 211 cooperate with the locking holes 41 on the side shafts 4, and the side shafts 4 can be locked during the mold closing process, further ensuring the sealing and stability of the side molds 21 and the bottom mold 22 in the mold closing state, and ensuring the molding quality of the blank. When taking out the parts, the unlocking operation of the locking cylinders 211 can make the side shafts 4 move smoothly in the subsequent steps, thereby improving the controllability and safety of the equipment operation.

[0053] The implementation principle of the high-pressure forming machine for high-pressure forming sanitary ceramic production in the embodiment of the present application is as follows: after the forming of the workpiece is completed, the two side molds 21 are opened, and the demolding rod 151 can make the formed embryo body separate from the side mold 21 and be located above the bottom mold 22. After the overall demolding of the side mold 21 is completed, the positions of the multiple demolding rods 151 are adjusted by the demolding plate 15, so that the demolding rods 151 and the embryo body can be completely separated, and only the embryo body is retained on the upper side of the bottom mold 22. At the same time, the positioning column can be inserted into the positioning hole to limit the bottom mold 22 to the middle position of the molding mold 2, and it will not move with the opening of the side mold 21.

[0054] At the same time, when the two side molds 21 are opened, the outer ends of the two groups of side shafts 4 are inserted into the side molds 21, which can play a role in supporting the bottom mold 22 and the workpieces on the bottom mold 22. Then, the material pick-up car drives the slide 3 to move. When the slide 3 moves to the lower side of the bottom mold 22, the oblique sections of the two guide rails 31 will first be inserted into the grooves 25. Then, with the movement of the slide 3, the oblique sections of the guide rails 31 will contact the cylindrical cam 5 peripheral walls at the ends of the side shafts 4 on both sides of the base, and then gradually push each cylindrical cam 5 toward the middle of the bottom mold 22, driving the side shaft 4 to retract, until the straight section of the guide rail 31 contacts each cylindrical cam 5, and then each side shaft 4 retracts to the limit position, and the end of the side shaft 4 inserted in the side mold 21 is also pulled out of the side mold 21. As the slide 3 moves to the straight section of the guide rail 31 and abuts against the cylindrical cam 5, the slide 3 continues to move to drive the push terminal 33 to insert into the curved groove 25 of the cylindrical cam 5, thereby driving the cylindrical cam 5 to rotate, thereby causing the side shaft 4 to rotate upward and abut against the two sides of the embryo body on the bottom mold 22.

[0055] The slide 3 continues to move, and can drive the bottom mold 22 carrying the embryo to move out from between the two side molds 21 , and then the staff can easily remove the molded embryo from the bottom mold 22 .

[0056] After the embryo is removed from the upper side of the bottom mold 22, the slide 3 moves in the opposite direction, driving the bottom mold 22 back between the two side molds 21, and the bottom mold 22 will first be plugged into the positioning column to limit the position of the bottom mold 22, and then the slide 3 continues to move, pushing the terminal 33 will also first be separated from the cylindrical cams 5. At this time, the second elastic member 53 works to drive the side shafts 4 to maintain a horizontal state, and as the guide rail 31 gradually withdraws from the groove 25 of the bottom mold 22, the first elastic member 24 works to push the cylindrical cams 5 to move, so that the other end of each side shaft 4 is inserted into the corresponding side mold 21. Until the guide rail 31 is completely separated from the groove 25, the bottom mold 22 is also reassembled between the two side molds 21, and the mold closing operation can be performed again.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
