[0026] like Figures 1 to 13As shown, an embodiment of the present invention provides a ceramic embryo extrusion molding mechanism, including an extrusion device 1000, the extrusion device 1000 also includes a moving frame 1, a rotating motor 11 is arranged on one side of the moving frame 1, a support rod 12 is fixedly connected to the output shaft of the rotating motor 11, an extrusion block 2 is fixedly connected to the top of the support rod 12, a grabbing assembly 3 is fixedly connected to the bottom of the support rod 12, an oscillation cylinder 5 is arranged on one side of the moving frame 1, a molding assembly 4 is slidably connected in the oscillation cylinder 5, the moving frame 1 is used to control the position change and up and down rotation of the extrusion block 2 and the grabbing assembly 3, the grabbing assembly 3 is used to take the ceramic embryo out of the oscillation cylinder 5, the molding assembly 4 is used to place the raw embryo formed by the mixed clay and the binder, and after the operator pours the clay into the molding assembly 4, the operator needs to control the moving frame 1 to make the grabbing assembly 3 grab the molding assembly 4 , so that the molding component 4 can be placed in the oscillation cylinder 5 by the grabbing component 3. When the molding component 4 enters the oscillation cylinder 5, the molding component 4 will vibrate under the action of the oscillation cylinder 5, so that the clay inside the molding component 4 is evenly distributed. When the molding component 4 enters the oscillation cylinder 5, the grabbing component 3 is separated from the molding component 4 and rotates so that the extrusion block 2 is located below the grabbing component 3. Then the extrusion block 2 moves downward under the action of the moving frame 1 and squeezes the clay in the molding component 4 at the same time. When the extrusion is completed, the extrusion block 2 is separated from the molding component 4 and rotates in the opposite direction so that the grabbing component 3 is located below the extrusion block 2. Then the grabbing component 3 extends into the oscillation cylinder 5 under the action of the moving frame 1. After the oscillation is completed, the molding component 4 is taken out. Finally, only the molding component 4 needs to be disassembled to obtain the extruded ceramic embryo.

[0027] As an implementation method in this embodiment, Figures 2 to 7As shown, the grabbing assembly 3 includes a grabbing portion 31, the top of the grabbing portion 31 is rotatably connected to an auxiliary box 32, the lower portion of the grabbing portion 31 is rotatably connected to a group of evenly spaced hollow plates 33, the grabbing portion 31 includes a fixed plate 311, the top of the fixed plate 311 is fixedly connected to a limiting column 312, the middle position of the limiting column 312 is provided with a rotation limiting groove, the surface of the limiting column 312 is provided with a group of annular array of serrated structures, the bottom edge position of the fixed plate 311 is fixedly connected to a group of annular array of slide plates 313, one side of the slide plate 313 is fixedly connected to a group of evenly spaced grabbing rods 314, the bottom of the auxiliary box 32 is a hollow structure, the top of the hollow structure of the auxiliary box 32 is fixedly connected to a rotating column 321, one side of the rotating column 321 The first gear 323 is fixedly connected to the first motor 322, and the first gear 323 is fixedly connected to the output shaft of the first motor 322. The bottom limit rotation of the rotating column 321 is connected to the limit column 312, and the first gear 323 is meshed with the serrated structure on the side of the limit column 312. A slide groove 331 is provided on the top of the hollow plate 33, and a group of positioning holes 332 are provided on both sides of the hollow plate 33. The slide plate 313 is slidably connected to the inside of the hollow plate 33, and the grabbing rod 314 on one side of the slide plate 313 is inserted into the positioning hole 332 on one side of the hollow plate 33. The connecting column between the slide plate 313 and the fixed plate 311 is slidably connected in the slide groove 331. When the molding component 4 filled with clay is grabbed to the oscillation cylinder 5, the hollow plate 33 will first be on the movable frame 1. Under the action of the action, the hollow plate 33 moves to the top of the forming component 4, and then the hollow plate 33 moves downward along the surface of the forming component 4. When the hollow plate 33 moves to the bottom of the forming component 4, the first motor 322 starts to rotate. When the first motor 322 rotates, the limiting column 312 meshing with the first gear 323 starts to rotate. During the rotation of the limiting column 312, the slide plate 313 rotates in the hollow plate 33, so that the grabbing rod 314 extends out from the positioning hole 332 of the hollow plate 33 and is inserted into the positioning hole 332 on one side of the adjacent hollow plate 33. During the process of extending the grabbing rod 314, each grabbing rod 314 is respectively inserted between the forming components 4. Then, when the grabbing part 31 rises, the grabbing rod 314 will rise synchronously. Since the grabbing rod 314 is evenly inserted on the forming component 4, the forming component 4 will rise synchronously with the grabbing rod 314. When the grabbing part 31 puts the forming component 4 into the oscillating cylinder 5, the first motor 322 rotates in the opposite direction. At this time, the fixed plate 311 will move the sliding plate 313 in the opposite direction in the hollow plate 33, so that the grabbing rod 314 is retracted into the hollow plate 33. At this time, since the connection between the grabbing rod 314 and the forming component 4 is lost, when the grabbing part 31 rises, the forming component 4 will still be in the oscillating cylinder 5. When the rotating motor 11 rotates, the positional relationship between the extrusion block 2 and the grabbing component 3 is interchanged. When the extrusion block 2 moves downward under the action of the moving frame 1, the extrusion block 2 will extrude the forming component 4. After the extrusion is completed,The extrusion block 2 will move upwards and rotate 180 degrees under the action of the rotating motor 11, and the position relationship with the grabbing assembly 3 will be exchanged again. When the grabbing part 31 moves downwards into the oscillating cylinder 5 again, the first motor 322 rotates again, so that the grabbing rod 314 extends again and is inserted into the forming assembly 4. When the grabbing part 31 moves upwards, the forming assembly 4 will move upwards synchronously with the grabbing part 31 until it leaves the oscillating cylinder 5.

[0028] In this embodiment, if Figures 2 to 7 As shown, when the grabbing portion 31 transfers the molding component 4, the grabbing rods 314 on the four slides 313 will be evenly distributed on the molding component 4, making the molding component 4 more stable during the movement, avoiding large-scale shaking that may cause gaps in the ceramic embryo. At the same time, through the rotation of the rotating motor 11 and the movement of the moving frame 1, the extrusion and transfer of the ceramic embryo can also be achieved.

[0029] As an implementation method in this embodiment, Figures 7 to 13As shown, the molding component 4 includes a group of sealing plates 41 in an annular array, four sealing plates 41 are provided, and two adjacent sealing plates 41 are slidably connected through a sealing groove, a group of oscillation grooves 411 with uniform intervals are opened on the sealing plate 41, a restraining plate 43 is sleeved on the bottom of a group of sealing plates 41 in an annular array, a hollow plate 33 is slidably connected between the two sealing plates 41, an inner lining plate is installed on the inner side of the sealing plate 41, a gap is left between the inner lining plate and the sealing plate 41, a spring is installed in the gap between the inner lining plate and the sealing plate 41, and two adjacent inner lining plates are also slidably connected through a sealing groove, an oscillation rod 42 is slidably connected in the oscillation groove 411 on the sealing plate 41, a baffle is fixedly connected to the oscillation rod 42, and the oscillation rod 42 is An oscillation head 421 is fixedly connected to one end, a first spring 422 is arranged between the sealing plate 41 and the baffle plate, an inclined surface is arranged at the other end of the oscillation rod 42, a grabbing rod 314 is inserted between the two adjacent oscillation rods 42, the end of the oscillation head 421 abuts against the outer side of the inner lining plate, a group of guide grooves 51 in an annular array are opened on the inner wall of the oscillation cylinder 5, an oscillation part 52 is fixedly connected in the guide groove 51, the inner wall of the oscillation cylinder 5 is connected to the side of the hollow plate 33, one end of the oscillation rod 42 with an inclined surface is slidably connected to one side of the oscillation part 52, the oscillation part 52 includes a mounting plate 521, one side of the mounting plate 521 is fixedly connected to a group of evenly spaced one-way grooves 522, an inclined block 523 is rotatably connected in the one-way groove 522, and the inclined block 523 is rotatably connected to the A torsion spring 524 is arranged between the mounting plates 521. When the grabbing assembly 3 grabs the forming assembly 4, the operator first needs to place the adhesive on the restraining plate 43, and then insert the four sealing plates 41 in sequence and fix them on the restraining plate 43 by bolts, and connect the two adjacent sealing plates 41, and then pour the clay into it. Finally, when the grabbing assembly 3 is sleeved on the sealing plate 41 and the grabbing rod 314 is extended, the extended grabbing rod 314 will be inserted between the two adjacent oscillation rods 42. When the grabbing assembly 3 rises, since the bottom of the oscillation rod 42 is supported by the grabbing rod 314, the oscillation rod 42 will rise synchronously with the sealing plate 41 and the restraining plate 43. When the grabbing assembly 3 enters with the restraining plate 43 When the oscillation tube 5 is in the oscillation tube 5, the oscillation rod 42 will contact the inclined block 523. When the oscillation rod 42 contacts the inclined block 523 from top to bottom, since the bottom of the inclined block 523 is supported by the one-way groove 522, the oscillation rod 42 will move horizontally under the action of the inclined block 523, so that the oscillation head 421 hits the inner lining plate of the sealing plate 41. Since the green embryos in the inner lining plate have a certain softness, the inner lining plate vibrates under the impact of the oscillation head 421, while driving the spring of the inner wall to quickly compress and rebound, vibrating the inner lining plate, so that the green embryos in the inner lining plate will be distributed more evenly. When the inclined surface of the oscillation rod 42 separates from the inclined block 523, the compressed first spring 422 will stretch, so that the oscillation rod 42 returns to its original position. As the restraining plate 43 continues to descend,The oscillation rod 42 will contact different inclined blocks 523. When the binding plate 43 is located at the bottom of the oscillation tube 5, the oscillation head 421 stops vibrating. When the forming component 4 gradually moves upward away from the oscillation tube 5 under the action of the grabbing component 3, the oscillation rod 42 will also move upward synchronously and contact the inclined block 523 from bottom to top. At this time, since there is no support on the top of the inclined block 523, the inclined block 523 will rotate upward under the push of the oscillation rod 42, so that the oscillation rod 42 can pass smoothly. When the oscillation rod 42 is separated from the inclined block 523, the compressed torsion spring 524 will be released and the inclined block 523 will recover.

[0030] In this embodiment, if Figures 7 to 13 As shown, when the restraining plate 43 descends in the oscillation cylinder 5, the oscillation rod 42 at the bottom will continuously collide with the inclined block 523, and the vibration frequency of the oscillation rod 42 gradually decreases from bottom to top. Therefore, the clay at the bottom of the inner lining plate inside the sealing plate 41 is subjected to the greatest vibration. By vibrating the clay at the bottom, the entire clay can be subjected to a certain degree of vibration, so that the green embryo can be evenly distributed in the molding component 4. On the other hand, by providing a detachable molding component 4, when the ceramic embryo in the molding component 4 is formed, the operator first needs to detach the grabbing component 3 from the molding component 4, and then fix the grabbing component 3 fixed between the restraining plate 43 and the sealing plate 41. The bolts between them are removed, and finally the sealing plates 41 around the extruded ceramic embryo are removed in turn. The operation is simple, and adhesion between the ceramic embryo and the sealing plates 41 and the restraining plates 43 is avoided, thereby ensuring the integrity of the ceramic embryo. In addition, sealing grooves are provided between two adjacent sealing plates 41 and between two adjacent inner lining plates, which can not only make the connection between the two sealing plates 41 tighter, but also prevent the clay from being exposed from between the two sealing plates 41 when the clay is extruded. At the same time, the material of the inner lining plate is set to a smooth surface of tungsten carbide steel bonded cemented carbide, which has the advantages of non-stick mold, high mold life and good anti-sticking property, thereby preventing the ceramic embryo from sticking when it is taken out and facilitating demolding.

[0031] The working principle of the technical solution provided by the present invention is as follows: First, the operator pours the clay into the molding component 4 (such as Figure 8As shown), the operator then controls the mobile frame 1 to move, grabs the grabbing component 3 on the molding component 4, and places the molding component 4 in the oscillation cylinder 5 by the grabbing component 3. When the molding component 4 enters the oscillation cylinder 5, the molding component 4 will vibrate under the action of the oscillation cylinder 5, so that the clay inside the molding component 4 is evenly distributed. When the molding component 4 enters the oscillation cylinder 5, the grabbing component 3 is separated from the molding component 4 and rotates so that the extrusion block 2 is located below the grabbing component 3. Then the extrusion block 2 moves downward under the action of the mobile frame 1 and simultaneously extrude the clay in the molding component 4. When the extrusion is completed, the extrusion block 2 is separated from the molding component 4 and rotates in the opposite direction so that the grabbing component 3 is located below the extrusion block 2. Then the grabbing component 3 extends into the oscillation cylinder 5 under the action of the mobile frame 1 and takes out the molding component 4. Finally, it is only necessary to disassemble the molding component 4 to obtain the extruded ceramic embryo.

[0032] Specifically: when the grabbing assembly 3 grabs the molding assembly 4 filled with clay to the oscillating cylinder 5, the hollow plate 33 will first move to the top of the molding assembly 4 under the action of the moving frame 1, and then the hollow plate 33 will move downward along the outer surface of the molding assembly 4. When the hollow plate 33 moves to the bottom of the molding assembly 4, the first motor 322 starts to rotate, driving the limiting column 312 engaged with the first gear 323 to start rotating. During the rotation of the limiting column 312, the slide plate 313 will rotate in the hollow plate 33, so that the grabbing rod 314 extends out from the positioning hole 332 of the hollow plate 33 and is inserted into the positioning hole 332 on one side of the adjacent hollow plate 33. During the extension of the grabbing rod 314, each grabbing rod 314 will be inserted between the molding assemblies 4 respectively. Then, when the grabbing portion 31 rises, the grabbing rod 314 will rise synchronously. Since the grabbing rod 314 is evenly inserted on the molding assembly 4, the molding assembly 4 will rise synchronously with the grabbing rod 314 at this time. When the gripping portion 31 puts the forming component 4 into the oscillation tube 5, the oscillation rod 42 contacts the inclined block 523 from top to bottom. Since the bottom of the inclined block 523 is supported by the one-way groove 522, the oscillation rod 42 will move horizontally under the action of the inclined block 523, so that the oscillation head 421 hits the inner lining plate inside the sealing plate 41. Since the unextruded clay has a certain softness, the inner lining plate vibrates under the impact of the oscillation head 421, while driving the spring of the inner wall to quickly compress and rebound, vibrating the inner lining plate, so that the raw embryo inside the inner lining plate will be more evenly distributed. When the inclined surface of the oscillation rod 42 separates from the inclined block 523, the compressed first spring 422 will stretch, so that the oscillation rod 42 returns to its original position. As the restraining plate 43 continues to descend, the oscillation rod 42 will contact different inclined blocks 523. When the restraining plate 43 is located at the bottom of the oscillation tube 5, the oscillation head 421 stops vibrating.

[0033] When the restraining plate 43 descends in the oscillation tube 5, the oscillation rod 42 at the bottom will continuously collide with the inclined block 523, and the vibration frequency of the oscillation rod 42 gradually decreases from bottom to top. Therefore, the clay at the bottom of the inner lining plate inside the sealing plate 41 is subjected to the greatest vibration. By vibrating the clay at the bottom, the entire clay can be subjected to a certain degree of vibration, so that the green embryo can be evenly distributed in the molding component 4. On the other hand, by providing a detachable molding component 4, when the ceramic embryo in the molding component 4 is formed, the operator first needs to evacuate the grabbing component 3 from the molding component 4, then remove the bolts fixed between the restraining plate 43 and the sealing plate 41, and finally remove the sealing plates 41 around the ceramic embryo in turn. The invention can be simply operated, and the adhesion between the ceramic embryo and the sealing plate 41 and the restraining plate 43 is avoided, so as to ensure the integrity of the ceramic embryo and reduce the probability of damage to the embryo. In addition, sealing grooves are arranged between two adjacent sealing plates 41 and between two adjacent lining plates, which can not only make the connection between the two sealing plates 41 tighter, but also prevent the clay from being exposed from between the two sealing plates 41 when the clay is extruded. The first motor 322 rotates in the reverse direction. At this time, the fixed plate 311 will move the slide plate 313 in the reverse direction in the hollow plate 33, so that the grabbing rod 314 is retracted into the hollow plate 33. At this time, since the connection between the grabbing rod 314 and the molding component 4 is lost, when the grabbing part 31 rises, the molding component 4 will still be in the oscillation cylinder 5.

[0034] Subsequently, the extrusion block 2 moves downward under the action of the moving frame 1, and the extrusion block 2 will extrude the molding component 4 until the embryo is formed. After the extrusion is completed, the extrusion block 2 moves upward through the moving frame 1, and under the action of the rotating motor 11, it rotates 180 degrees, and the position relationship with the grabbing component 3 is exchanged. When the grabbing part 31 moves downward into the oscillation cylinder 5 again, the first motor 322 rotates again, so that the grabbing rod 314 extends out again and is inserted into the molding component 4. When the grabbing part 31 moves upward, the molding component 4 will move upward synchronously with the grabbing part 31 until it leaves the oscillation cylinder 5. When the grabbing part 31 transfers the molding component 4, the grabbing rods 314 on the four slides 313 will be evenly distributed on the molding component 4, making the molding component 4 more stable during the movement, avoiding large-scale shaking that causes gaps in the ceramic embryo.

[0035] When the forming component 4 gradually moves upward away from the oscillating cylinder 5 under the action of the grabbing component 3, the oscillating rod 42 will also move upward synchronously and contact the inclined block 523 from bottom to top. At this time, since there is no support on the top of the inclined block 523, the inclined block 523 will rotate upward under the push of the oscillating rod 42, so that the oscillating rod 42 can pass smoothly. When the oscillating rod 42 is separated from the inclined block 523, the compressed torsion spring 524 will be released, and the inclined block 523 will recover. Furthermore: by rotating the motor 11, the ceramic embryo can be squeezed and transferred. When the grasping component 3 grasps the forming component 4, the operator first needs to insert the four sealing plates 41 in sequence and fix them on the binding plate 43 through bolts, and connect the two adjacent sealing plates 41, and then pour the clay into it. Finally, when the grasping component 3 is sleeved on the sealing plate 41 and the grasping rod 314 is extended, the grasping rod 314 extended at this time will be inserted between the two adjacent oscillation rods 42. When the grasping component 3 rises, since the bottom of the oscillation rod 42 is supported by the grasping rod 314, the oscillation rod 42 will rise synchronously with the sealing plate 41 and the binding plate 43. When the grasping component 3 enters the oscillation tube 5 with the binding plate 43, the oscillation rod 42 will contact the inclined block 523.

[0036] When the oscillation rod 42 contacts the inclined block 523 from top to bottom, since the bottom of the inclined block 523 is supported by the one-way groove 522, the oscillation rod 42 will move horizontally under the action of the inclined block 523, so that the oscillation head 421 hits the inner lining plate of the sealing plate 41. Since the clay has a certain softness, the inner lining plate vibrates under the impact of the oscillation head 421, while driving the spring of the inner wall to quickly compress and rebound, vibrating the inner lining plate, so that the inside of the raw embryo in the inner lining plate will be more evenly distributed. When the inclined surface of the oscillation rod 42 separates from the inclined block 523, the compressed first spring 422 will stretch, so that the oscillation rod 42 returns to its original position. As the restraining plate 43 continues to descend, the oscillation rod 42 will contact different inclined blocks 523. When the restraining plate 43 is located at the bottom of the oscillation tube 5, the oscillation head 421 stops vibrating. When the molding component 4 gradually leaves the oscillation tube 5 upward under the action of the grabbing component 3, the oscillation rod 42 will also move upward synchronously and contact the inclined block 523 from bottom to top.

[0037] At this time, since there is no support on the top of the inclined block 523, the inclined block 523 will rotate upward under the push of the oscillation rod 42, allowing the oscillation rod 42 to pass smoothly. When the oscillation rod 42 is separated from the inclined block 523, the compressed torsion spring 524 will be released and the inclined block 523 will be restored. When the restraining plate 43 descends in the oscillation cylinder 5, the oscillation rod 42 at the bottom will continuously collide with the inclined block 523, and the vibration frequency of the oscillation rod 42 will gradually decrease from bottom to top. Therefore, the clay at the bottom of the lining plate inside the sealing plate 41 is subjected to the greatest degree of vibration. By vibrating the clay at the bottom, the entire clay can be subjected to a certain degree of vibration, so that the green embryo can be evenly distributed in the molding component 4. On the other hand, By setting a detachable molding component 4, when the ceramic embryo in the molding component 4 is formed, the operator first needs to remove the grasping component 3 from the molding component 4, then remove the bolts fixed between the restraining plate 43 and the sealing plate 41, and finally remove the sealing plate 41 and the inner lining plate around the extruded ceramic embryo in turn. The operation is simple, and the adhesion between the ceramic embryo and the sealing plate 41 and the restraining plate 43 is avoided, the integrity of the ceramic embryo is ensured, and the probability of damage to the embryo is reduced. In addition, sealing grooves are provided between two adjacent sealing plates 41 and between two adjacent inner lining plates, which can not only make the connection between the two sealing plates 41 tighter, but also prevent the clay from being exposed from between the two sealing plates 41 when the clay is extruded.
