Description

Technical Field

[0001] This invention relates to the field of grouting technology, and more particularly to a demolding device for a grouting production line. Background Technology

[0002] In the ceramics industry, the production and shaping of daily-use ceramics mostly employs slip casting. Slip casting is relatively simple: slurry made from the raw material is poured into a plaster mold. Because plaster molds are absorbent, the water in the slurry near the inner wall of the mold is absorbed by the porous plaster, forming a layer of clay on the inner wall of the mold with the same shape as the mold's inner wall. This clay layer thickens over time. After a period of time, the excess slurry is poured off, while the clay layer near the inner wall of the plaster mold remains inside. After another period of time, the clay layer naturally shrinks and detaches from the mold, allowing the rough blank to be removed.

[0003] For some irregularly shaped ceramics or ceramic products formed by slip casting with special slurry, the ceramic blank cannot be directly removed from the plaster mold during the demolding stage. The plaster mold needs to be separated first to complete the demolding. Therefore, the plaster mold adopts a separable structure.

[0004] In traditional techniques, for separable plaster molds, before grouting, it is necessary to manually wrap the plaster mold with elastic bands to bring the separated plaster molds together before grouting can be carried out. When demolding, it is necessary to manually unwrap the elastic bands wrapped around the plaster molds before demolding can be carried out. This production method is not only time-consuming and labor-intensive, but also inefficient and not conducive to automated production. Summary of the Invention

[0005] The purpose of this invention is to address the deficiencies in the prior art by proposing a demolding device for a grouting production line. This device comprises a clamping end drive assembly, a clamping assembly, and a transmission assembly. The clamping end drive assembly drives the transmission assembly, which in turn causes the clamping assembly to clamp and release the plaster mold. This replaces the existing method of manually securing the plaster mold with an elastic band, and the use of a mold-turning mechanism and a mold-pushing mechanism in conjunction. The device detaches the plaster mold from the plaster mold conveyor belt onto the demolding worktable, thereby liberating labor productivity, improving production efficiency, and achieving automated production.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0057] The present invention provides a demolding device for a grouting production line, such as... Figures 1 to 9 As shown, it includes a plaster mold clamp 2, a plaster mold conveyor belt 3, a mold rotation mechanism 4, a mold pushing mechanism 5, and a demolding worktable 6, all installed on the demolding frame 1.

[0058] The plaster mold clamp 2 includes a clamping assembly 22 and a clamping end drive assembly 23;

[0059] The clamping assembly 22 is fixedly installed on the mold placement plate 21, the clamping end drive assembly 23 is installed on the gantry frame 238, and the mold placement plate 21 is placed on the plaster mold conveyor belt 3 and is used to carry the plaster mold A.

[0060] The clamping end driving component 23 is used to drive the clamping component 22 to retract so that the clamping component 22 clamps the plaster mold A;

[0061] The mold-changing mechanism 4 includes a mold-changing component 41 and a mold-lifting component 42;

[0062] The mold rotation assembly 41 is used to rotate the mold placement plate 21 so that the opening of the clamping assembly 22 faces the demolding worktable 6;

[0063] The lifting mold assembly 42 is used to drive the rotating mold assembly 41 to perform lifting and lowering movements, so that the rotating mold assembly 41 can contact and separate from the mold placement plate 21;

[0064] The mold pushing mechanism 5 is used to push the plaster mold A from the mold placement plate 21 to the demolding worktable 6.

[0065] In traditional techniques, for separable plaster molds, before grouting, it is necessary to manually wrap the plaster mold with elastic bands to bring the separated parts together before grouting can proceed. During demolding, the elastic bands must be manually unwrapped. This production method is not only time-consuming and labor-intensive but also inefficient and unsuitable for automated production. To address these issues, this application proposes a demolding device for a grouting production line. The device utilizes the cooperation of the clamping end drive component 23 and the clamping component 22 of the plaster mold clamp 2 to clamp and release the plaster mold A placed on the mold placement plate 21. A mold rotation mechanism 4 rotates the mold placement plate 21 so that the opening of the clamping component 22 faces the demolding worktable 6, facilitating the pushing mechanism 5 to push the plaster mold A onto the demolding worktable 6 for demolding. The device also uses the mold rotation mechanism 4 and the plaster mold clamp 2 to reset the demolded empty plaster mold A for subsequent grouting.

[0066] Specifically, it includes:

[0067] The plaster mold clamp 2, plaster mold conveyor belt 3, mold rotation mechanism 4, mold pushing mechanism 5, and demolding worktable 6 are installed on the demolding frame 1. The plaster mold clamp 2 is used to clamp the plaster mold A before grouting and to release the plaster mold clamp 2 during the demolding stage, so that the plaster mold A can be released from the plaster mold clamp 2 for easy demolding. The plaster mold conveyor belt 3 transports the plaster mold A held by the plaster mold clamp 2. Then, the clamping end drive assembly 23 of the plaster mold clamp 2 drives the clamping assembly 22 to release the plaster mold A. Then, the plaster mold conveyor belt 3 transports the released plaster mold A to the mold rotation mechanism 4. The mold lifting assembly 42 of the mold rotation mechanism 4 drives the mold rotation assembly 41 of the mold rotation mechanism 4 to rise, so that the mold rotation assembly 41 contacts the mold placement plate 21 carrying the plaster mold A. The mold placement plate 21, which carries the plaster mold A, is rotated so that the opening of the clamping component 22 faces the demolding worktable 6. Then, the plaster mold conveyor belt 3 continues to transport the plaster mold A carried by the mold placement plate 21 to the mold pushing mechanism 5. The mold pushing mechanism 5 pushes the plaster mold A from the mold placement plate 21 toward the opening of the clamping component 22 to the demolding worktable 6. The production personnel manually demold the plaster mold A on the demolding worktable 6. After demolding, the production personnel need to put the empty plaster mold A back onto the empty mold placement plate 21, and then rotate the plaster mold A back to its original position through the mold rotation mechanism 4. Then, the plaster mold clamp 2 clamps the plaster mold A, and the plaster mold conveyor belt 3 transports the clamped empty plaster mold A to the grouting mechanism for grouting again.

[0068] Preferred, such as Figure 5 and Figure 6 As shown, the clamping assembly 22 includes a clamping end fixing frame 221, on which a transmission assembly 222 is installed in a crisscross pattern. The transmission assembly 222 includes a first transmission lead screw 2221, a second transmission lead screw 2222, a first auxiliary guide rod 2223, and a second auxiliary guide rod 2224. The first transmission lead screw 2221 and the first auxiliary guide rod 2223 are used to install the first clamping member 223, and the second transmission lead screw 2222 and the second auxiliary guide rod 2224 are used to install the second clamping member 224 and the third clamping member 225.

[0069] The clamping assembly 22 is provided with a first calibration component, and the clamping end driving assembly 23 is provided with a second calibration component. The first calibration component cooperates with the second calibration component to enable the clamping end driving assembly 23 to complete the power connection with the first transmission screw 2221 and the second transmission screw 2222.

[0070] The clamping end drive assembly 23 is used to drive the first transmission screw 2221 to transmit power so that the first clamping member 223 moves up and down along the first transmission screw 2221 and the first auxiliary guide rod 2223.

[0071] The clamping end drive assembly 23 is used to drive the second transmission screw 2222 to transmit power so that the first clamping member 223 and / or the second clamping member 224 move laterally along the second transmission screw 2222 and the second auxiliary guide rod 2224.

[0072] The plaster mold A is clamped by a clamping end driving component 23, which drives the clamping component 22 to clamp the plaster mold A, instead of using an elastic band to wrap the plaster mold A in the traditional technology. Specifically, this includes:

[0073] In this application, the clamping assembly 22 includes a clamping end fixing frame 221, on which the transmission assembly 222 is mounted. The transmission assembly 222 includes a longitudinally arranged first transmission lead screw 2221 and a first auxiliary guide rod 2223, and a transversely arranged second transmission lead screw 2222 and a second auxiliary guide rod 2224. In this embodiment, two first auxiliary guide rods 2223 are provided, one on the left and one on the right, arranged side by side on both sides of the first transmission lead screw 2221. Two second auxiliary guide rods 2224 are provided, one above and one below, arranged side by side on both sides of the second transmission lead screw 2222. The upper end of the first transmission lead screw 2221 is equipped with the first clamping member 223, and its lower end is vertically fixed to the edge of the mold placement plate 21. The mold placement plate 21 is used to place the plaster mold A. The clamping assembly 22 is installed on the edge of the mold placement plate 21, so that the mold placement plate 21 has sufficient space to place the plaster mold A. The second transmission lead screw 2222... The two ends of component 2 are respectively equipped with a second clamping member 224 and a third clamping member 225; when the clamping end driving assembly 23 drives the first transmission screw 2221 and the second transmission screw 2222, the first clamping member 223 can move up and down along the first transmission screw 2221 and the first auxiliary guide rod 2223, and the second clamping member 224 and / or the third clamping member 225 can move laterally along the second transmission screw 2222 and the second auxiliary guide rod 2224. It should be noted that... In this embodiment, when the first clamping member 223 descends, it can clamp the upper part of the plaster mold A on the mold placement plate 21. When the second clamping member 224 and / or the third clamping member 225 moves laterally toward the clamping end fixing frame 221, they can clamp the two sides of the plaster mold A on the mold placement plate 21, thereby completing the clamping of the upper end face and the two side end faces of the plaster mold A, thus replacing the manual use of elastic bands to wrap the plaster mold A to ensure that the plaster mold A does not separate.

[0074] Furthermore, this application enables the clamping end drive assembly 23 to complete the power docking with the first transmission lead screw 2221 and the second transmission lead screw 2222 through the first calibration component and the second calibration component. This avoids the situation where the clamping end drive assembly 23 fails to dock with the first transmission lead screw 2221 and the second transmission lead screw 2222 due to inaccurate positioning caused by the movement of the workpiece.

[0075] Preferably, the first clamping member 223, the second clamping member 224 and the third clamping member 225 each include a clamping end and a sliding end;

[0076] The sliding end is provided with a clamping slider 2261, which can slide along the transmission assembly 222;

[0077] The clamping end is provided with a clamping rod 2262, which is mounted on the clamping slider 2261. The clamping rod 2262 is perpendicular to the transmission assembly 222.

[0078] Furthermore, in this embodiment, the first clamping member 223, the second clamping member 224, and the third clamping member 225 are all provided with a clamping end and a sliding end. The clamping end includes a slider, and the clamping slider 2261 is connected to the clamping end. The clamping end includes a clamping rod 2262. It should be noted that the clamping rod 2262 of the first clamping member 223 needs to be perpendicular to the first transmission lead screw 2221 and the first auxiliary guide rod 2223, and the clamping rod 2262 of the second clamping member 224 and the third clamping member 225 needs to be perpendicular to the second transmission lead screw 2222 and the second auxiliary guide rod 2224 in order to achieve the clamping effect.

[0079] The function of the clamping slider 2261 is that when the first transmission screw 2221 and the second transmission screw 2222 are in transmission, the clamping slider 2261 can slide along the transmission assembly 222, thereby driving the clamping rod 2262 to clamp the plaster mold A or release the plaster mold A.

[0080] Preferred, such as Figure 3 and Figure 4 As shown, the clamping end drive assembly 23 includes a drive motor 233 and a telescopic cylinder 234. The drive motor 233 is mounted on the first fixed plate 231 and is used to dock with the transmission assembly 222. The telescopic cylinder 234 is mounted on the second fixed plate 232.

[0081] The first fixing plate 231 is provided with a cylinder slider 235, and the second fixing plate 232 is connected to a cylinder guide rail 236. The cylinder slider 235 is slidably installed on the cylinder guide rail 236 and can slide along the cylinder guide rail 236.

[0082] The first fixing plate 231 has a cylinder docking position 237, which is used to dock the telescopic cylinder 234.

[0083] Furthermore, in this embodiment, the clamping end drive component 23 is used to drive the clamping component 22. To ensure production efficiency, multiple clamping components 22 are provided and transported by a conveyor belt. However, to reduce production costs, it is not possible to have one clamping component 22 corresponding to a set of clamping end drive components 23. Therefore, a small number of clamping end drive components 23 need to be set at fixed positions, and a set of clamping end drive components 23 provides power to multiple clamping components 22. To achieve the above effect, this application proposes the following specific structure:

[0084] In this embodiment, the gantry frame 238 is used to fix the clamping end drive assembly 23. The clamping end drive assembly 23 includes a first fixing plate 231 and a second fixing plate 232. The first fixing plate 231 is equipped with a drive motor 233, which is used to connect with the first transmission screw 2221 and the second transmission screw 2222 to provide power to the clamping assembly 22. The second fixing plate 232 is equipped with a telescopic cylinder 234. The first fixing plate 231 is equipped with a cylinder slider 235, and the second fixing plate 232 is equipped with a cylinder guide rail 236. The cylinder slider 235 is slidably mounted on the cylinder guide rail 236. Since the cylinder slider 235 is fixed to the first fixing plate 231, when the cylinder slider 235 slides along the cylinder guide rail 236, the first fixing plate 231 can slide together, that is, the drive motor 233 on the first fixing plate 231 can slide together.

[0085] Furthermore, the first fixing plate 231 is provided with a cylinder docking position 237, which is used to dock with the telescopic cylinder 234. Therefore, when the telescopic cylinder 234 completes docking with the cylinder docking position 237, when the air shaft of the telescopic cylinder 234 extends or retracts, it will apply a telescopic force to the first fixing plate 231. This force will simultaneously act on the cylinder slider 235 on the first fixing plate 231, thereby driving the cylinder slider 235 to slide along the cylinder guide rail 236, thus realizing the telescopic sliding of the drive motor 233 on the first fixing plate 231. When the drive motor 233 can perform telescopic drive, a set of clamping end drives can be completed. The driving component 23 provides power to multiple clamping components 22. When a clamping component 22 is conveyed to the group of clamping end driving components 23, the driving motor 233 slides out to connect with the first transmission screw 2221 and the second transmission screw 2222 of the clamping component 22. It provides power so that the first transmission screw 2221 and the second transmission screw 2222 drive the first clamping member 223, the second clamping member 224 and the third clamping member 225 to clamp or release the plaster mold A. After clamping or releasing the plaster mold A, the driving motor 233 slides back again to disconnect from the group of clamping components 22 and waits for the next group of clamping components 22.

[0086] Furthermore, in this embodiment, one end of the second transmission screw 2222 is provided with a positive thread and the other end is provided with a reverse thread, the second clamping member 224 is installed at one end of the second transmission screw 2222, and the third clamping member 225 is installed at the other end of the second transmission screw 2222;

[0087] When the clamping end driving assembly 23 drives the second transmission screw 2222, the second clamping member 224 and the third clamping member 225 simultaneously perform opposite lateral movements.

[0088] In this embodiment, to minimize production costs, this application provides only two sets of clamping end drive assemblies 23 for the transmission components 222 of the transverse and longitudinal transmissions. One set of clamping end drive assemblies 23 has a drive motor 233 for engaging with the first transmission lead screw 2221, and the other set of clamping end drive assemblies 23 has a drive motor 233 for engaging with the second transmission lead screw 2222. Specifically, in this embodiment, the second transmission lead screw 2222 may have a forward thread at one end and a reverse thread at the other end. The second clamping member 224 and the third clamping member 225 are respectively installed at both ends of the second transmission lead screw 2222. Therefore, when... When the drive motor 233 drives the second transmission screw 2222, the clamping sliders 2261 of the second clamping member 224 and the third clamping member 225 can slide simultaneously along the second transmission screw 2222 and the second auxiliary guide rod 2224. The sliding directions of the two clamping members are opposite to each other. That is, the second clamping member 224 and the third clamping member 225 can slide simultaneously toward the clamping end fixing frame 221 to complete the clamping of the plaster mold A, or they can slide simultaneously toward the clamping end fixing frame 221 to release the plaster mold A. Through the above structure, the second clamping member 224 and the third clamping member 225 can slide coaxially in opposite directions.

[0089] Furthermore, in this embodiment, one end of the second transmission screw 2222 is provided with a transmission thread;

[0090] One end of the second transmission screw 2222 with the transmission thread is connected to the second clamping member 224 or the third clamping member 225, while the other end is not connected to another clamping member.

[0091] When the clamping end drive assembly 23 drives the second transmission screw 2222, the second clamping member 224 or the third clamping member 225 moves laterally, while the other clamping member remains stationary.

[0092] Furthermore, in this embodiment, the second transmission screw 2222 can be configured to have a transmission thread at only one end. The end with the transmission thread can be connected to the second clamping member 224 or the third clamping member 225. Therefore, when the drive motor 233 drives the second transmission screw 2222, the clamping member at the end connected to the transmission thread can slide along the second transmission screw 2222 and the second auxiliary guide rod 2224, while the clamping member at the other end that is not connected to the transmission thread remains stationary. Through the sliding of the clamping member at one end connected to the transmission thread and the structure of the clamping member at the other end that remains stationary, the plaster mold A can be clamped or released.

[0093] Preferably, the first calibration component includes a positioning block 227 installed at the end of the first transmission lead screw 2221 and the second transmission lead screw 2222, and the positioning block 227 is provided with a calibration hole 228;

[0094] The second calibration component includes a positioning pin 239 disposed on the first fixing plate 231, the positioning pin 239 being located on both sides of the air shaft of the drive motor 233;

[0095] The positioning pin 239 is used to cooperate with the calibration hole 228 to realize the power connection between the air shaft of the drive motor 233 and the first transmission lead screw 2221 and the second transmission lead screw 2222.

[0096] In this embodiment, the first calibration component is a positioning block 227, which is installed at the ends of the first transmission lead screw 2221 and the second transmission lead screw 2222. The positioning block 227 has a calibration hole 228 on the side facing the drive motor 233. The second calibration component is a positioning pin 239. Each drive motor 233 is equipped with two sets of positioning pins 239, which are arranged on both sides of the air shaft of the drive motor 233, one on the left and one on the right, for cooperating with the calibration hole 228 on the positioning block 227. Through the cooperation of the positioning pins 239 and the calibration hole 228 on the positioning block 227, the air shaft of the drive motor 233 can be more accurately connected with the first transmission lead screw 2221 and the second transmission lead screw 2222, avoiding the problem of docking error.

[0097] Preferred, such as Figure 7 As shown, the mold rotation assembly 41 includes a mold rotation cylinder 411 mounted on the mold rotation mounting frame 410, a bearing seat 412, and a rotating shaft 413 fitted inside the bearing seat 412;

[0098] One end of the rotating shaft 413 is equipped with a tray 414, and the other end is equipped with a rotating swing arm 417. The rotating swing arm 417 is connected to the telescopic air shaft of the mold rotating cylinder 411.

[0099] The mold mounting bracket 410 is also equipped with a swing limit block 416, which has a swing space.

[0100] The rotating arm 417 can swing within the swing space.

[0101] In this embodiment, the bearing seat 412 is sleeved on the outside of the rotating shaft 413. The rotating shaft 413 is erected on the top of the mold mounting bracket 410. A tray 414 is provided on the top of the rotating shaft 413. Before rotating the plaster mold A, the tray 414 will contact the mold placement plate 21. The rotating arm 417 is installed at the bottom of the rotating shaft 413. The rotating arm 417 is connected to the telescopic air shaft of the mold rotating cylinder 411. When the mold rotating cylinder 411 drives the telescopic air shaft to extend or retract, it can drive the rotating arm 417 to swing within the swing space of the swing limit block 416, thereby driving the rotating shaft 413 to rotate. The rotation of the rotating shaft 413 will drive the tray 414 on its top to rotate synchronously. Since the tray 414 is in contact with the mold placement plate 21, the mold placement plate 21 will also rotate synchronously, thereby driving the clamping assembly 22 and the plaster mold A to rotate.

[0102] Preferred, such as Figure 8 As shown, the mold lifting assembly 42 includes a mold lifting cylinder 422 and a mold lifting guide post 423 mounted on the mold lifting mounting plate 421;

[0103] The lifting mold guide post 423 is fitted with a linear bearing 424, and the linear bearing 424 is fixedly installed with the rotating mold mounting frame 410.

[0104] The lifting air shaft 425 of the lifting cylinder 422 is fixedly installed with the rotating mold mounting frame 410.

[0105] In this embodiment, the four corners of the upper part of the lifting mold mounting plate 421 are respectively equipped with lifting mold guide pillars 423, and the bottom of the lifting mold cylinder 422 is equipped with a lifting cylinder 422. The lifting air shaft 425 of the lifting mold cylinder 422 passes through the lifting mold mounting plate 421 to connect with the rotating mold mounting frame 410.

[0106] Furthermore, a linear bearing 424 is sleeved on the outside of the lifting mold guide post 423. Since the linear bearing 424 is fixed to the mold mounting frame 410, when the lifting mold cylinder 422 drives the lifting air shaft 425 to lift and lower, it will drive the mold mounting frame 410 to lift and lower along the lifting mold guide post 423 through the linear bearing 424, thereby realizing the overall lifting and lowering of the mold mounting frame 410. Since the mold mounting assembly 41 is installed on the mold mounting frame 410, it can be driven to lift and lower the entire mold mounting assembly 41 synchronously. It should be noted that when the plaster mold A needs to be rotated, the lifting mold assembly 42 will drive the mold mounting assembly 41 to rise so that the tray 414 contacts the mold placement plate 21. After the rotation is completed, the lifting mold assembly 42 needs to drive the mold mounting assembly 41 to fall so that the tray 414 is removed from the mold placement plate 21 to avoid the tray 414 affecting the transportation of the mold placement plate 21.

[0107] Preferred, such as Figure 9 As shown, the mold pushing mechanism 5 includes a first mold pushing bracket 51, a second mold pushing bracket 52 and a mold pushing cylinder 53 installed on the demolding frame 1;

[0108] The first ejector mold support 51 is provided with an ejector mold guide rail 54 and an ejector mold slider 55 slidably mounted with the ejector mold guide rail 54;

[0109] The second push mold bracket 52 is horizontally mounted on the top of the push mold slider 55, and the second push mold bracket 52 is equipped with a push rod 56 and a push plate 57, the push plate 57 being connected to the push air shaft of the push mold cylinder 53.

[0110] In this embodiment, when the mold rotation assembly 41 rotates the mold placement plate 21 so that the opening of the clamping assembly 22 faces the demolding worktable 6, the plaster mold conveyor belt 3 transports the plaster mold A after rotation to the mold pushing mechanism 5. The mold pushing cylinder 53 drives the push shaft to retract, and applies a retraction force to the second mold pushing bracket 52 through the push plate 57, causing the mold pushing slider 55 fixed to the second mold pushing bracket 52 to retract and slide along the mold pushing guide rail 54, driving the push rod 56 on the second mold pushing bracket 52 to retract towards the plaster mold A. The push rod pushes the plaster mold A. Since the plaster mold A is in a loose state with the clamping assembly 22 at this time, and the opening of the clamping assembly 22 faces the demolding worktable 6, the plaster mold A can be smoothly pushed onto the demolding worktable 6 for demolding by production personnel.

[0111] Preferably, the clamping rod 2262 is fitted with a protective sleeve 2263.

[0112] Furthermore, in this embodiment, the clamping rod 2262 is fitted with a protective sleeve 2263 to prevent damage to the plaster mold A when clamping it.

[0113] Furthermore, in this embodiment, the contact surface between the plaster mold A and the clamping rod 2262 can be designed as a groove structure, so that the clamping rod 2262 fits into the plaster mold A, thereby increasing the clamping force of the clamping rod 2262 on the plaster mold A and further preventing the plaster mold A from shifting during transportation.

[0114] Preferably, the tray 414 is provided with a cushioning pad 415.

[0115] In this embodiment, the tray 414 is used to contact the mold placement plate 21. Therefore, when the lifting assembly 42 lifts the tray 414 to contact the mold placement plate 21, in order to avoid the situation where the tray 414 impacts the mold placement plate 21 due to the lifting force and causes the plaster mold A to move, this application provides a buffer pad 415 on the tray 414. While buffering the lifting force of the tray 414, it can also prevent the tray 414 from directly colliding with the mold placement plate 21 and causing damage to the tray 414 or the mold placement plate 21.

[0116] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
