Description

Technical Field

[0001] This application relates to the technical field of slip casting equipment, in particular to an internal force clamping slip casting device for forming green bodies. Background Art

[0002] Slip casting is a forming method used to manufacture daily-use ceramics or building ceramics with complex shapes: by selecting appropriate materials to make a slurry, and then pouring it into a slip casting mold to form a green body according to the mold. Slip casting molds are generally divided into two-piece molds and four-piece molds. These molds need to be kept locked during the forming process to overcome the mold expansion force and ensure the quality of slip casting production. Conventional slip casting molds use hydraulic cylinders installed on the outer frame for locking. With this locking structure, the hydraulic cylinder needs to maintain an external force to clamp the frame. Since the hydraulic cylinder needs to ensure the accuracy of the applied force and also needs to provide a sufficiently large pressure to keep the oil cylinder pressurized, the manufacturing, replacement, and maintenance costs are high. After long-term operation, there will be a small amount of internal leakage in the valve parts of the hydraulic system. When the oil cylinder pressure is lower than the set pressure, the hydraulic system needs to be started to re-pressurize, which is unstable and energy-consuming; on the other hand, the frame needs to be enlarged in volume to adapt to the hydraulic cylinder, resulting in a large floor area, heavy weight, and cumbersome assembly and debugging process for the slip casting mold.

[0020] Advantages of the present application:

[0021] 1. An internal force clamping and grouting device for a formed blank body according to the present application. By providing a clamping structure on the first side mold, when it is necessary to clamp the first side mold and the second side mold, only the clamping member needs to be driven. Through the clamping member, the clamping push seat can be driven to approach the side clamping module, thereby driving the first side mold and the second side mold to approach each other. During this process, the guiding and locking assembly provides a guiding effect on the clamping push seat, the push rod drives the internal force clamping assembly to move, and the clamping push seat moves towards the side clamping module. When the stroke limit is reached, the first side mold abuts against the second side mold, and at the same time, the self-locking connecting rod reaches the dead point position to achieve self-locking, so as to ensure that the first side mold and the second side mold are tightly abutted for grouting. Using the clamping member to replace the continuous driving of the hydraulic cylinder, it is not necessary to continuously apply force during the grouting process to ensure the fitting of the two side molds. Even after long-term use, the normal use of the clamping member can be ensured. At the same time, it can effectively reduce the floor area required by the grouting equipment, improve the service life on the basis of ensuring the clamping effect, and help to achieve lightweight and reduce production and manufacturing costs.

[0022] 2. An internal force clamping and grouting device for a formed blank body according to the present application. By providing a rotatable guiding pressure rod to adapt to the side mold, when the guiding pressure rod rotates, it drives the side clamping module to rotate and then locks or disengages from the first side mold, making the locking process between the clamping member and the upper mold fast and accurate, ensuring the locking efficiency and the locking effect.

[0023] 3. An internal force clamping and grouting device for a formed blank body according to the present application. When adapting to a four-opening mold, only an upper clamping mechanism and a lower clamping mechanism need to be added on the basis of the side clamping mechanism. The upper mold is clamped with the side mold by the upper clamping mechanism, and the lower mold is clamped with the side mold by the lower clamping mechanism, so as to complete the clamping and grouting of the four-opening mold. Compared with the hydraulic cylinder, it is not necessary to adjust the hydraulic pressure of each hydraulic cylinder as accurately as the hydraulic cylinder, so that the overall structure of the grouting device is compact and easy to use, ensuring the locking efficiency and quality.

[0038] Referring to Figure 1 and Figure 2 , an internal force clamping grouting device for a formed blank body, comprising an outer frame 1 and an inner frame 2 disposed in the outer frame 1, further comprising a mold structure 3 disposed in the inner frame 2 and a clamping structure 4 disposed in the mold structure 3. Under the action of the clamping structure 4, the mold structure 3 can be tightened to perform grouting molding to obtain a blank body, and achieve lightweight and miniaturization, reducing the overall weight and floor area. The blank body obtained by the internal force clamping grouting device for a formed blank body can specifically be a sanitary ware device such as a basin or a toilet, but is not limited thereto. In other embodiments, the internal force clamping grouting device for a formed blank body can also be used to produce other ceramic products, and the application scenarios of the internal force clamping grouting device for a formed blank body are not specifically limited.

[0039] Specifically, the outer frame 1 is used for support and installation, the inner frame 2 is disposed in the outer frame 1 and is rotatably connected to the outer frame 1, and the mold structure 3 is disposed in the inner frame 2. The mold structure 3 includes at least a first side mold 31 and a second side mold 32. In this embodiment, taking a two-opening mold as an example, the mold structure 3 includes a first side mold 31 and a second side mold 32. The first side mold 31 and the second side mold 32 are oppositely disposed. The first side mold 31 is located on one side of the inner frame 2, and the second side mold 32 is located on the other side of the inner frame 2.

[0040] Referring to Figure 1 , Figure 2 and Figure 3 , in order to lock the first side mold 31 and the second side mold 32, the clamping structure 4 includes side clamping mechanisms 41. There are two side clamping mechanisms 41, and the two side clamping mechanisms 41 are respectively located on both sides in the width direction of the first side mold 31 and the second side mold 32. The side clamping mechanism 41 includes a fixed seat 411 disposed on the first side mold 31, a clamping base 412 disposed on the fixed seat 411, and a clamping push seat 413 slidably connected to the clamping base 412. A clamping member 414 is connected between the clamping base 412 and the clamping push seat 413; the clamping member 414 includes a guiding and clamping assembly 4141 connected to the clamping base 412 and the clamping push seat 413 and an internal force clamping assembly 4142 for driving the clamping push seat 413.

[0041] The mode-locking base 412, the mode-locking push base 413 and the mode-locking member 414 are arranged on the same side of the fixed base 411. The mode-locking base 412 is fixedly installed through the mode-locking member 414, and the mode-locking push base 413 is connected to the mode-locking base 412 through the mode-locking member 414. Specifically, the mode-locking member 414 includes a guiding and locking assembly 4141 connected to the mode-locking base 412 and the mode-locking push base 413, and an internal-force mode-locking assembly 4142 for driving the mode-locking push base 413. The internal-force mode-locking assembly 4142 is located in the middle of the mode-locking base 412.

[0042] Referring to Figures 1 to 5 , the guiding and locking assembly 4141 includes a guiding pressure rod 41411 rotatably connected to the mode-locking push base 413. One end of the guiding pressure rod 41411 in the length direction is provided with a side locking module 41412. The second side mold 32 is provided with a side locking groove 321 for cooperating with the side locking module 41412. The guiding pressure rod 41411 is rotatably connected to the side locking groove 321, and the side locking module 41412 abuts against or disengages from the side locking groove 321 in a rotating manner. More specifically, the side locking module 41412 can pass through the side locking groove 321 in the initial state. After the side locking module 41412 passes through the side locking groove 321, it rotates under the drive of the driving member 415, and the side locking module 41412 rotates 90 degrees and abuts against both sides of the side locking groove 321, so as to realize the installation and abutment with the second side mold 32.

[0043] Referring to Figure 3 and Figure 6, in order to cooperate with the mold clamping member 414, guide holes for cooperating with the guide pressure rod 41411 are provided on both sides of the mold clamping base 412 and the mold clamping push base 413. The guide pressure rod 41411 is inserted through the guide holes and rotatably connected to the guide holes. One end in the length direction of the guide pressure rod 41411 is connected to the driving member 415. In this embodiment, this end of the guide pressure rod 41411 is inserted through the fixed seat 411 and then connected to the driving member 415, and the guide pressure rod 41411 is rotatably connected to the fixed seat 411. In order to ensure the assembly accuracy and service life, the guide pressure rod 41411 has a shoulder. A positioning piece 414111 and a wear-resistant pad are sleeved and installed on one side of the shoulder of the guide pressure rod 41411. One side of the positioning piece 414111 abuts against the shoulder, the other side of the positioning piece 414111 abuts against the wear-resistant pad, and the wear-resistant pad abuts against the fixed seat 411. By providing the shoulder, the positioning piece 414111 and the wear-resistant pad, when the guide pressure rod 41411 is installed, making the shoulder of the guide pressure rod 41411 abut against the positioning piece 414111 can ensure the assembly accuracy of the guide pressure rod 41411, making the position of the side lock module 41412 at the end of the guide pressure rod 41411 away from the base accurate, and increasing the cooperation accuracy between the guide pressure rod 41411 and the second side mold 32; the wear-resistant pad can reduce the damage caused by the rotation of the guide pressure rod 41411 to the base, thereby increasing the service life. In addition, in order to facilitate the pre-tightening force adjustment of the side lock module 41412, an adjusting nut is provided between the fixed seat 411 and the mold clamping base 412. The adjusting nut is rotatably connected to the mold clamping base 412, and the guide pressure rod 41411 has a threaded portion threadedly connected to the adjusting nut. When the guide pressure rod 41411 rotates to cooperate with the second side mold 32, first rotate the adjusting nut to loosen the adjusting nut so as not to affect the rotation of the guide pressure rod 41411. After the guide pressure rod 41411 rotates and cooperates with the second side mold 32, rotate the adjusting nut to lock the guide pressure rod 41411. By adjusting the tightness of the adjusting nut, the pre-tightening force between the guide pressure rod 41411 and the second side mold 32 can be realized.

[0044] Refer to Figure 7 , Figure 8 and Figure 9, the internal force clamping module 4142 includes a push rod 41421 connected to the clamping push seat 413 and a self-locking connecting rod 41422 arranged on the push rod 41421, and the clamping push seat 413 approaches or moves away from the side clamping module 41412. Specifically, one end of the push rod 41421 in the length direction passes through the clamping base 412 and is then connected to the driving member 415, and the other end of the push rod 41421 in the length direction is connected to the self-locking connecting rod 41422 and passes through the clamping base 412. To ensure the service life of the push rod 41421, a wear-resistant ring is sleeved on the end of the push rod 41421 located in the clamping base 412. To ensure the clamping effect, there are two self-locking connecting rods 41422, and the two self-locking connecting rods 41422 are respectively located on both sides of the push rod 41421, and the two self-locking connecting rods 41422 are symmetrically arranged with respect to the push rod 41421. Similarly, there are two guiding and clamping components 4141, and the two guiding and clamping components 4141 are respectively arranged on both sides of the two self-locking connecting rods 41422 away from the push rod 41421; and the two guiding and clamping components 4141 are symmetrically arranged with respect to the push rod 41421.

[0045] The self-locking connecting rod 41422 includes a first connecting rod 414221, a second connecting rod 414222 and a third connecting rod 414223 that are hinged to each other. The first connecting rod 414221, the second connecting rod 414222 and the third connecting rod 414223 are connected to the corresponding components through pin shafts to achieve rotation. One end of the first connecting rod 414221, the second connecting rod 414222 and the third connecting rod 414223 in the length direction are hinged to the same end point. The other end of the first connecting rod 414221 is hinged to the clamping base 412, the other end of the second connecting rod 414222 is hinged to the push rod 41421, and the other end of the third connecting rod 414223 is hinged to the clamping push seat 413. To cooperate with the installation of the self-locking connecting rod 41422, the push rod 41421 is provided with a connecting block, and the second connecting rods 414222 of the two self-locking connecting rods 41422 are respectively hinged to both sides of the connecting block.

[0046] By arranging the push rod 41421 and the self-locking link 41422 in this way, when the push rod 41421 moves driven by the mold clamping member 414, the push rod 41421 will drive the second link 414222 to move through the connecting block. The moving second link 414222 drives the first link 414221 and the third link 414223 to move. The moving first link 414221 and the third link 414223 drive the mold clamping push seat 413 to move along the guiding pressure rod 41411, thus continuously approaching the side locking module 41412. The second side mold 32 is pressed against one side of the side locking module 41412 close to the mold clamping push seat 413, and the first side mold 31 is pressed against one side of the mold clamping push seat 413 close to the side locking module 41412. Under the action of the power cylinder, the resistance arm L1 is gradually shortened, and the power arm L2 is gradually lengthened to increase the force. When the push rod 41421 reaches the stroke limit, the self-locking link 41422 will reach the dead point to form a self-locking structure. By using the self-locking function of the two side self-locking links 41422, it can ensure that the mold clamping push seat 413 drives the first side mold 31 to always abut against the second side mold 32 to achieve locking for grouting. And during the grouting process, the driving member 415 does not need to apply force to the mold clamping member 414 all the time.

[0047] In order to ensure that the mold clamping mechanism is structurally compact to adapt to the side mold, the mold clamping push seat 413 is provided with a push seat installation groove for accommodating the self-locking link 41422. The third link 414223 is hinged in the push seat installation groove. Similarly, the mold clamping base 412 is provided with a base installation groove 4121 for accommodating the self-locking link 41422, and the first link 414221 is hinged in the base installation groove 4121. By providing the base installation groove 4121 in the mold clamping base 412 and the push seat installation groove in the mold clamping push seat 413, and using the base installation groove 4121 and the push seat installation groove to adaptively install and accommodate the corresponding links, on the one hand, it can effectively reduce the weight of the mold clamping base 412 and the mold clamping push seat 413, and on the other hand, it can further streamline the size of the mold clamping member 414, so that the side mold adapted to it can further reduce the volume and the required floor area.

[0048] The driving member 415 includes a first driving member 4151 for driving the push rod 41421 and a second driving member 4152 for driving the guiding pressure rod 41411. The first driving member 4151 is arranged on one side of the mold clamping base 412 away from the mold clamping push seat 413. The second driving member 4152 is arranged on one side of the fixed seat 411 away from the mold clamping base 412. In this embodiment, the first driving member 4151 is a power cylinder, and the power cylinder is installed on the mold clamping base 412 by means of threaded connection to achieve disassembly. The second driving member 4152 is a pneumatic actuator, and the pneumatic actuator is installed on the fixed seat 411 by means of threaded connection to achieve disassembly. The power cylinder and the pneumatic actuator are both prior arts and can be obtained by purchase, and their structures and principles will not be elaborated.

[0049] Looking back Figure 1 and Figure 2 In order to conveniently drive the first side mold 31 and the second side mold 32, the grouting device further includes a transverse movement driving structure 5 for driving the first side mold 31 and the second side mold 32 to move away from or close to each other. Specifically, the inner frame 2 is provided with a first transverse guide rail and a second transverse guide rail. The first transverse guide rail and the second transverse guide rail are horizontally arranged. The first side mold 31 is slidably connected to the first transverse guide rail, and the second side mold 32 is slidably connected to the second transverse guide rail. The transverse movement driving structure 5 includes a first transverse driving member 51 and a second transverse driving member 52. The first transverse driving member 51 is connected to the first side mold 31, and the second transverse driving member 52 is connected to the second side mold 32.

[0050] In this embodiment, the first transverse driving member 51 includes a first transverse gear rotatably connected to the inner frame 2 and a first transverse chain covering the first transverse gear. The first side mold 31 is mounted on the first transverse chain. The second transverse driving member 52 includes a second transverse gear rotatably connected to the inner frame 2 and a second transverse chain covering the second transverse gear. The second side mold 32 is mounted on the second transverse chain. The first transverse gear and the second transverse gear are driven by a motor to rotate. When the transverse gear rotates, it will drive the corresponding transverse chain to move, and the moving transverse chain drives the corresponding side mold to slide on the guide rail to achieve approaching or separating from each other.

[0051] During the grouting molding process, the mold structure 3 is tilted at a certain angle according to the process requirements. For this reason, the molding grouting device further includes an inclination driving structure 6 for driving the inner frame 2 to incline. One end of the inclination driving structure 6 is hinged to the outer frame 1, and the other end of the inclination driving structure 6 is hinged to the inner frame 2. The inclination driving structure 6 can specifically be an oil cylinder, and the inclination driving structure 6 can specifically be a cylinder or an electric cylinder, etc. Driven by the inclination driving structure 6, the inner frame 2 rotates relative to the outer frame 1, and the inner frame 2 drives the mold structure 3 to rotate to achieve inclination.

[0052] It can be understood that the mold clamping structure 4 is not only applicable to two-opening molds, but also applicable to four-opening molds. Taking the four-opening mold as an example: On the basis of the two-opening mold, the mold structure 3 further includes an upper mold 33 and a lower mold 34. The upper mold 33 is slidably connected to the inner frame 2, and the upper mold 33 is located above the first side mold 31 and the second side mold 32. The lower mold 34 is located below the first side mold 31 and the second side mold 32.

[0053] In order to drive the upper mold 33, the internal force clamping and grouting device for forming green bodies further includes a lifting drive structure 7 for driving the upper mold 33. In this embodiment, lifting rails are provided on both sides of the inner frame 2. One side of the upper mold 33 away from the lower mold 34 has an upper mold base, and lifting guide wheels are provided on the upper mold base. The lifting guide wheels are fitted and installed on the lifting rails; the lifting drive structure 7 is provided on the upper mold base and connected to the inner frame 2. The lifting drive structure 7 includes a gear provided on the upper mold base and a rack provided on the inner frame 2. The gear is driven by a motor to rotate. Under the rotation of the gear, the rack moves, thereby driving the upper mold base and the upper mold 33 to move. It can be understood that the lifting drive structure 7 may specifically also be a lead screw guide rail structure or a cylinder structure for driving.

[0054] In order to lock the upper mold 33 and the lower mold 34, the mold clamping structure 4 further includes an upper locking mechanism 42 for locking the upper mold 33 to the first side mold 31 and the second side mold 32, and a lower locking mechanism 43 for locking the lower mold 34 to the first side mold 31 and the second side mold 32; the upper locking mechanism 42 is provided on the upper mold 33 and abuts against the first side mold 31 and the second side mold 32; the lower locking mechanism 43 is provided on the lower mold 34 and abuts against the first side mold 31 and the second side mold 32. There are two upper locking mechanisms 42 and two lower locking mechanisms 43. The two upper locking mechanisms 42 are located on both sides of the connection between the upper mold width direction and the first side mold 31 and the second side mold 32, and the two lower locking mechanisms 43 are located on both sides of the connection between the lower mold width direction and the first side mold 31 and the second side mold 32.

[0055] In this embodiment, the structure of the upper locking mechanism 42 is the same as that of the side locking mechanism 41; the upper locking mechanism 42 has two upper locking modules corresponding to the side locking module 41412. One of the upper locking modules abuts against the first side mold 31, and the other upper locking module abuts against the second side mold 32. The structure of the lower locking mechanism 43 is the same as that of the side locking mechanism 41; the lower locking mechanism 43 has two lower locking modules corresponding to the side locking module 41412. One of the lower locking modules abuts against the first side mold 31, and the other lower locking module abuts against the second side mold 32.

[0056] By setting the upper mold clamping mechanism and the lower mold clamping mechanism in this way, after the first side mold 31 and the second side mold 32 are closed, the lower part of the first side mold 31 and the second side mold 32 abuts against the lower mold and is locked by the lower locking mechanism 43; the upper part of the first side mold 31 and the second side mold 32 abuts against the upper mold and is locked by the upper locking mechanism 42, and the locking of the four-opening mold can be completed. By setting the mold clamping structure 4 in this way, the production and manufacturing cost can be reduced by at least 20%.

[0057] The exemplary embodiments of the present disclosure have been specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, arrangements, or implementation methods described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
