Abstract
Description
Technical Field
[0001] This application relates to the technical field of slip casting equipment, and in particular to a suspended internal force clamping slip casting device. Background Art
[0002] Slip casting is a method for forming ceramic green bodies. Using this method can make the shape of the ceramic green body regular, and at the same time can relatively purely maintain the original shape of the ceramic sculpture. It has the advantages of being relatively easy to master the forming operation technology, being conducive to batch replication, having a relatively short forming cycle, and consuming less raw materials. It is particularly suitable for the forming of green bodies with complex structures such as ceramic sanitary ware or building ceramics.
[0003] In the process of slip casting, first inject the slurry into the mold. After the slurry dries to form a green body with a certain strength, open the mold, and then manually take out the green body in the mold for the next process. When dealing with relatively heavy green bodies, a relatively large upward traction force is required to take out the green body by the up-and-down mold opening method. To achieve rapid mold opening and green body taking, there are suspended slip casting devices. However, these suspended slip casting devices usually use hydraulic cylinders installed on the outer frame for locking, that is, lock the mold by continuously applying an external force. On the one hand, the hydraulic cylinder needs to continuously apply a relatively large pressing force, resulting in a relatively large volume of the hydraulic cylinder and the slip casting equipment, a large floor area, and being inconvenient for installation. On the other hand, the hydraulic cylinder needs to provide a large enough pressure to maintain the pressure of the oil cylinder, resulting in high manufacturing, replacement, and maintenance costs. When working in a long-term force application state, there will be a small amount of internal leakage in the valve parts of the hydraulic system. When the pressure of the oil cylinder is lower than the set pressure, it is necessary to start the hydraulic system to re-pressurize, which is unstable and energy-consuming.

It can also ensure the normal and stable use of the mold-locking member during long-term use. At the same time, it can effectively reduce the floor area required by the grouting equipment, while ensuring the locking effect and improving the service life.
[0019] 2. For a suspended internal force mold-locking grouting device of the present application, by setting a rotatable guiding pressure rod to adaptively connect the internal mold and the first outer mold, when the guiding pressure rod rotates, it drives the mold-locking block to rotate and then locks or disengages from the internal mold, making the locking process of the mold-locking member and the internal mold fast and accurate, ensuring the locking efficiency and locking effect.
[0020] 3. For a suspended internal force mold-locking grouting device of the present application, by setting suspension seats and using the suspension rods to adaptively hang the first outer mold and the second outer mold, after the grouting is completed and the first outer mold and the second outer mold are disengaged from the internal mold, the first outer mold and the second outer mold can swing and rotate around the suspension rod as the axis, so as to tilt at a certain angle to facilitate quick mold removal.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.
[0035] Refer to Figure 1 and Figure 2 , an embodiment of the present application provides a suspended internal force mold-locking grouting device, which includes a frame 1, and further includes a suspension structure 2 slidably connected to the frame 1, a mold structure 3 provided on the suspension structure 2, and a mold-locking structure 4 for locking the mold structure 3. The mold-locking structure 4 locks the mold structure 3 in a self-locking manner, so that the mold structure 3 can be tightly pressed to perform grouting molding to obtain a green body, which helps to reduce the overall weight and floor area. It should be noted that the green body obtained by the grouting device can specifically be a sanitary ware device such as a basin or a toilet, but is not limited thereto. In other embodiments, the grouting device can also be used to produce other ceramic products, and the application scenarios of the grouting device are not specifically limited.
[0036] The frame 1 is used to support and install each structure. The mold structure 3 at least includes an inner mold 31 and a first outer mold 32. In this embodiment, the mold structure 3 includes an inner mold 31, a first outer mold 32 provided on one side of the inner mold 31, and a second outer mold 33. The first outer mold 32 is located on one side of the inner mold 31, and the second outer mold 33 is located on the side of the inner mold 31 away from the first outer mold 32.
[0037] Refer to Figure 1 , Figure 2 and Figure 3, the suspension structure 2 includes a suspension frame 21 disposed on the frame 1 and a plurality of suspension seats 22, and the mold structure 3 is hung and installed on the suspension frame 21 and the suspension seats 22. In order to adapt to the installation of the suspension seats 22, the frame 1 is provided with sliding guide rails 11, which extend horizontally along the length direction of the frame 1. A plurality of suspension seats 22 are slidably connected to the sliding guide rails 11, so that the suspension seats 22 can reciprocate along the length direction of the sliding guide rails 11, thereby driving the mold structure 3 to move. Specifically, the suspension frame 21 is located in the middle of the frame 1, and the inner mold 31 is installed on the suspension frame 21. The first outer mold 32 and the second outer mold 33 are hung on the suspension seats 22. In order to adapt to the installation of the corresponding outer molds, the suspension seats 22 have suspension rods 221; the first outer mold 32 has a first hanging seat, and the first hanging seat is hung on the suspension rod 221; the second outer mold 33 has a second hanging seat, and the second hanging seat is hung on the suspension rod 221. By setting the suspension seats 22 and the outer molds in this way, the outer molds can rotate around the suspension rod 221 after demolding, thereby driving the outer molds to rotate and swing for rapid demolding.
[0038] In order to drive the first outer mold 32 and the second outer mold 33 to move, the grouting device further includes a sliding drive structure 5 for driving the mold structure 3. The sliding drive structure 5 includes a first sliding drive member 51 and a second sliding drive member 52 respectively disposed at both ends of the frame 1. The first sliding drive member 51 is connected to the first outer mold 32, and the second sliding drive member 52 is connected to the second outer mold 33. The first sliding drive member 51 and the second sliding drive member 52 may specifically be cylinders, and may also specifically be oil cylinders or electric cylinders, etc. Driven by the sliding drive members, the first outer mold 32 and the second outer mold 33 approach or move away from each other to cooperate with the inner mold 31 for grouting or demolding.
[0039] The mold clamping structure 4 includes a first locking mechanism 41 for locking the first outer mold 32 and the inner mold 31 and a second locking mechanism 42 for locking the second outer mold 33 and the inner mold 31. The structure of the second locking mechanism 42 is the same as that of the first locking mechanism 41.
[0040] Refer to Figure 4 , Figure 5 and Figure 6, taking the first locking mechanism 41 as an example, the first locking mechanism 41 includes a mold clamping base 412 provided on the first outer mold 32 and a mold clamping push base 413 slidably connected to the mold clamping base 412. A mold clamping member 414 is connected between the mold clamping base 412 and the mold clamping push base 413. The mold clamping base 412, the mold clamping push base 413, and the mold clamping member 414 are arranged on the same side of the fixed seat 411. The mold clamping base 412 is installed and fixed through the mold clamping member 414, and the mold clamping push base 413 is connected to the mold clamping base 412 through the mold clamping member 414. Specifically, the mold clamping member 414 includes a guiding and locking assembly 4141 connected to the mold clamping base 412 and the mold clamping push base 413 and an internal force mold clamping assembly 4142 for driving the mold clamping push base 413. The internal force mold clamping assembly 4142 is located in the middle of the mold clamping base 412.
[0041] The guiding and locking assembly 4141 includes a guiding pressure rod 41411 rotatably connected to the mold clamping push base 413. One end in the length direction of the guiding pressure rod 41411 has a mold locking block 41412. The inner mold 31 is provided with a first locking groove 311 for cooperating with the mold locking block 41412. The guiding pressure rod 41411 is rotatably connected to the first locking groove 311, and the mold locking block 41412 abuts against or disengages from the first locking groove 311 by rotation. More specifically, the mold locking block 41412 can pass through the first locking groove 311 in the initial state. After the mold locking block 41412 passes through the first locking groove 311, it rotates under the drive of the driving member 415, and the mold locking block 41412 rotates ninety degrees and abuts against both sides of the first locking groove 311, so as to realize the installation and abutment with the inner mold 31.
[0042] 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. 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 inserted, 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, make the position of the mold clamping block 41412 at the end of the guide pressure rod 41411 away from the base accurate, and increase the cooperation accuracy between the guide pressure rod 41411 and the inner mold 31; the wear-resistant pad can reduce the damage caused by the rotating guide pressure rod 41411 to the base, thereby increasing the service life. In addition, to facilitate the pre-tightening force adjustment of the mold clamping block 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 inner mold 31, 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 inner mold 31, 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 inner mold 31 can be achieved.
[0043] Refer to Figure 7 and Figure 8, the internal force clamping module assembly 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. The clamping push seat 413 approaches or moves away from the clamping module 41412. Specifically, one end of the push rod 41421 in the length direction penetrates through the clamping base 412 and is then connected to the driving member 415. The other end of the push rod 41421 in the length direction is connected to the self-locking connecting rod 41422 and penetrates 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. 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. 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.
[0044] 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 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. 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. The second connecting rods 414222 of the two self-locking connecting rods 41422 are respectively hinged to both sides of the connecting block.
[0045] Refer to Figure 7 , Figure 8 and Figure 9, by setting 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 and thus continuously approach the mold clamping block 41412. The inner mold 31 is pressed tightly against one side of the mold clamping block 41412 close to the mold clamping push seat 413, and the first outer mold 32 is pressed tightly against one side of the mold clamping push seat 413 close to the mold clamping block 41412. Under the action of the power oil 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 utilizing the self-locking function of the two-side self-locking links 41422, it can be ensured that the mold clamping push seat 413 drives the first outer mold 32 to always abut against the inner mold 31 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.
[0046] In order to ensure that the mold clamping mechanism has a compact structure to adapt to the outer mold, the mold clamping push seat 413 is provided with a push seat installation groove for accommodating the self-locking link 41422, and 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 outer mold adapted to it can further reduce the volume and the required floor area.
[0047] The driving member 415 includes a first driving part 4151 for driving the push rod 41421 and a second driving part 4152 for driving the guiding pressure rod 41411; the first driving part 4151 is arranged on one side of the mold clamping base 412 away from the mold clamping push seat 413; the second driving part 4152 is arranged on one side of the fixed seat 411 away from the mold clamping base 412. In this embodiment, the first driving part 4151 is a power oil cylinder, and the power oil cylinder is installed on the mold clamping base 412 by means of threaded connection to achieve disassembly; the second driving part 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 oil cylinder and the pneumatic actuator are both prior arts and can be obtained by purchase, and their structures and principles will not be elaborated.
[0048] Looking back Figure 1 and Figure 2 Similarly, the second locking mechanism 42 is symmetrically arranged with respect to the suspension bracket 21 with the first locking mechanism 41. The second locking mechanism 42 penetrates into the inner mold 31 and abuts against the inner mold 31. Under the action of the second locking mechanism 42, the second outer mold 33 and the inner mold 31 are locked. To ensure the locking effect, there are two first locking mechanisms 41 and two second locking mechanisms 42. The two first locking mechanisms 41 are respectively located on both sides of the first outer mold 32, and the two second locking mechanisms 42 are respectively located on both sides of the second outer mold 33. Under the action of the first locking mechanism 41 and the second locking mechanism 42, the first outer mold 32, the second outer mold 33 and the inner mold 31 are locked. During the locking process, the driving member 415 only needs to provide the initial driving force and does not need to continuously provide pressure during the mold clamping and grouting processes, so that the volume of the driving member 415 is effectively reduced. Correspondingly, the volumes of the suspension structure 2 and the mold structure 3 can also be reduced, thereby achieving lightweight, reducing the floor area, and reducing the production and manufacturing cost by at least 20%.
[0049] The above specifically shows and describes the exemplary embodiments of the present disclosure. 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.
