Description

Technical Field

[0001] The invention belongs to the technical field of isostatic pressing, and in particular relates to a forming device, a forming method and application thereof in a ceramic ring. Background Art

[0002] Isostatic pressing technology is an advanced equipment that uses ultra-high pressure conditions in a closed high-pressure container to form products. Its working principle is based on Pascal's law, that is, the pressure of the medium (liquid or gas) in a closed container can be transmitted equally in all directions. This technology makes the pressure to which the formed workpiece is subjected in the high-pressure container the same as the pressure in still water at the same depth, thereby achieving high-density and high-precision material forming. This isostatic pressing technology has been widely used in the field of ceramic casting products. Specifically, powder or pre-pressed green body is encapsulated in an elastic rubber mold of appropriate size, placed in a high-pressure container and high-pressure liquid is applied. The incompressible nature of the liquid medium and the property of uniformly transmitting pressure are used to uniformly pressurize the rubber sleeve from all directions to form a green body.

[0003] For example, a Chinese patent with application number 2024104405000 discloses an isostatic pressing device and a method for producing a zirconia crucible, including a hydraulic press and a hydraulic cylinder, wherein the hydraulic cylinder is provided with a plurality of molding material frames, each of which is provided with a plurality of through holes, and each of which is vertically arranged, and each of which is provided with a spacing adjustment component. When placing a mold into a molding material frame, the device can adjust and increase the spacing between a plurality of molding material frames, so as to facilitate placing the mold into a plurality of molding material frames. However, when filling the material, quantitative feeding and uniform filling cannot be achieved, resulting in poor molding density.

[0004] Based on the above scheme, the ceramic material may agglomerate after being placed for a long time, resulting in uneven filling when filling the elastic mold, thereby causing voids on the surface or inside of the product molding, affecting the molding quality; it is impossible to achieve quantitative feeding and uniform filling when filling the material, resulting in poor molding density; in the initial state of applying high-pressure liquid, the elastic sleeve and the elastic column are subjected to different pressures at different positions. If the local pressure is too large, it will cause local deformation of the molded product, thereby affecting the molding quality of the product; since the molded product is prone to adhesion to the elastic column during demolding, manual demolding is likely to cause damage to the surface of the molded product, and the demolding effect is poor.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figures 1 to 9 As shown, a molding device of the present invention includes a machine body 101, and is characterized in that: a pressurizing cylinder 102 is arranged inside the machine body 101, a sealing cover 103 is arranged above the pressurizing cylinder 102, an elastic mold assembly 2 is arranged inside the pressurizing cylinder 102, and a blanking assembly 3 is arranged on one side of the machine body 101.

[0042] like Figure 5 , Figure 6 As shown, the elastic mold assembly 2 includes an elastic column 201 and an elastic sleeve 202 , and the elastic column 201 is arranged at the center position of the surface of the elastic sleeve 202 , a first end cover 203 is arranged below the elastic sleeve 202 , and a second end cover 204 is arranged at one end of the elastic sleeve 202 away from the first end cover 203 .

[0043] A support base 208 is provided below the first end cover 203 . The support base 208 is provided to limit the first end cover 203 . A limiting groove is provided at the position where the support base 208 is connected to the pressurizing cylinder 102 .

[0044] like Figure 2 , Figure 3 , Figure 4 As shown, the material discharge assembly 3 includes a material discharge barrel 301 , a material discharge hopper 302 is arranged below the material discharge barrel 301 , a feeding pipe is arranged on one side of the material discharge barrel 301 , a stirring shaft 303 is arranged inside the material discharge barrel 301 , and a plurality of stirring rods 304 are arranged on the surface of the stirring shaft 303 .

[0045] A stirring motor 307 is arranged above the lower barrel 301 , one end of the output shaft of the stirring motor 307 is connected to the stirring shaft 303 , a lifting mechanism 308 is arranged on the surface of the lower barrel 301 , and one end of the lifting mechanism 308 away from the lower barrel 301 is connected to the machine body 101 .

[0046] When in use, the stirring motor 307 is turned on, and the stirring motor 307 drives the stirring shaft 303 and the stirring rod 304 to rotate together, so that the stirring rod 304 stirs the ceramic material inside the lower barrel 301, and the height of the lower barrel 301 is adjusted by setting the lifting mechanism 308.

[0047] It is worth noting that a control valve is provided at the bottom of the lower hopper 302. When the control valve is opened, the lower hopper 302 starts to discharge materials, and when the control valve is closed, the lower hopper 302 stops discharging materials.

[0048] When in use, first open the sealing cover 103 on the molding component 1, then install the elastic mold component 2 inside the pressurizing cylinder 102, then open the second end cover 204, and fill the elastic mold component 2 with ceramic material through the unloading component 3. Specifically, turn on the stirring motor 307, and the stirring motor 307 drives the stirring shaft 303 and the stirring rod 304 to rotate together, so that the stirring rod 304 stirs the ceramic material inside the unloading cylinder 301, so as to achieve the purpose of stirring and crushing the agglomerated ceramic material inside the cylinder 301, and avoid uneven filling when filling the elastic mold, thereby causing voids on the surface or inside of the product molding, affecting the molding quality.

[0049] Then open the control valve to start unloading from the hopper 302. That is, the ceramic material inside the discharge barrel 301 is stirred and crushed by the stirring rod 304, and then falls from the hopper 302 into the mold cavity surrounded by the elastic column 201, the elastic sleeve 202 and the first end cover 203. The ceramic material in the mold cavity is manually flattened and sealed by the second end cover 204 after filling.

[0050] The sealing cover 103 is then placed on the pressurizing cylinder 102 to seal the pressurizing cylinder 102, and then high-pressure liquid is applied to the pressurizing cylinder 102 to apply pressure to the ceramic material in the elastic mold assembly 2 to form it. Finally, the high-pressure liquid is discharged after forming, and then the sealing cover 103 on the forming assembly 1 is opened, and the product formed in the elastic mold assembly 2 is manually taken out.

[0051] In the above process, it was found that quantitative feeding and uniform filling could not be achieved when filling materials, resulting in poor molding density; in the initial state of applying high-pressure liquid, the elastic sleeve 202 and the elastic column 201 are subjected to different pressures at different positions. If the local pressure is too large, it will cause local deformation of the molded product, thereby affecting the molding quality of the product; since the molded product is prone to adhesion to the elastic column 201 during demolding, manual demolding is likely to cause damage to the surface of the molded product, and the demolding effect is poor.

[0052] In order to solve the above problems, the forming device also includes:

[0053] like Figure 3 As shown, a dividing blade 306 is arranged inside the discharge hopper 302 , and a plurality of discharge ports are opened on the surface of the dividing blade 306 . A connecting shaft 305 is arranged at the center of the surface of the dividing blade 306 , and one end of the connecting shaft 305 away from the dividing blade 306 is fixedly connected to the stirring shaft 303 .

[0054] like Figure 5As shown, the inner wall of the pressurizing cylinder 102 is provided with a plurality of sealing grooves, an electric push rod 104 is arranged inside the sealing groove, and a vibration plate 105 is arranged at the output end of the electric push rod 104. There are multiple vibration plates 105, and the multiple vibration plates 105 are arranged in a ring shape on the outer surface of the elastic sleeve 202.

[0055] When in use, the controller controls the electric push rod 104 to reciprocate, and the electric push rod 104 drives the vibration plate 105 to reciprocate and collide with the elastic sleeve 202, so that the elastic sleeve 202 vibrates.

[0056] like Figures 6 to 9 As shown, an elastic ring 2011 is arranged inside the elastic column 201, elastic plates 2012 are arranged at intervals on the surface of the elastic ring 2011, a plurality of elastic strips 2013 are arranged at one end of the elastic plate 2012 away from the elastic ring 2011, and a pressure sensor is arranged inside the elastic ring 2011 for detecting the pressure magnitude at different positions of the elastic column 201.

[0057] An electric telescopic rod 206 is arranged at the center position of the surface of the elastic column 201, a rotating block 207 is arranged at the output end of the electric telescopic rod 206, a rotating seat 205 is arranged at the end of the electric telescopic rod 206 away from the rotating block 207, the rotating seat 205 is movably arranged at the center position of the surface of the pressurizing cylinder 102, a rotating groove is provided at the position where the rotating seat 205 is connected to the pressurizing cylinder 102, and a driving motor is assembled on the rotating seat 205.

[0058] A movable groove is provided at the position where the electric telescopic rod 206 is connected to the elastic column 201 . A socket 211 is provided at one end of the elastic column 201 close to the first end cover 203 . An electromagnetic plug is provided at the position of the rotating block 207 corresponding to the socket 211 .

[0059] A hydraulic rod 209 is provided at one end of the support base 208 close to the rotating base 205, and a clamping block 210 is provided at the end of the hydraulic rod 209 away from the support base 208. A clamping groove matching the clamping block 210 is opened on the surface of the rotating base 205. There are two support bases 208, and the two support bases 208 are respectively located on both sides of the rotating base 205.

[0060] When in use, the controller controls the hydraulic rod 209 to extend, and the hydraulic rod 209 pushes the clamping block 210 to move toward the direction close to the rotating seat 205, so that the clamping block 210 is fixed inside the clamping groove on the surface of the rotating seat 205.

[0061] In the process of filling the elastic mold assembly 2 with ceramic material through the blanking assembly 3, in the initial state, the rotating block 207 is at the bottom inside the elastic column 201, and then the controller controls the hydraulic rod 209 to extend, and the hydraulic rod 209 pushes the clamping block 210 to move toward the rotating seat 205, so that the clamping block 210 is fixed inside the clamping groove on the surface of the rotating seat 205, and then the driving motor is turned on, and the driving motor drives the rotating seat 205, the clamping block 210, the hydraulic rod 209, the support clamping seat 208, the first end cover 203, the elastic sleeve 202 and the elastic column 201 to rotate together.

[0062] In addition, the controller controls the electric push rod 104 to extend, and the electric push rod 104 drives the vibration plate 105 to move toward the direction close to the elastic sleeve 202, so that the vibration plate 105 fits the outer surface of the elastic sleeve 202.

[0063] Then turn on the stirring motor 307, and the stirring motor 307 drives the stirring shaft 303 and the stirring rod 304 to rotate together, so that the stirring rod 304 stirs the ceramic material inside the discharge barrel 301, and at the same time, the stirring shaft 303 drives the connecting shaft 305 and the dividing blade 306 to rotate together. By setting the dividing blade 306, the material after stirring and crushing by the stirring rod 304 is stirred for the second time, and the ceramic material with large lumps is effectively crushed. Then open the control valve, the ceramic material inside the discharge barrel 301 passes through the stirring rod 304 and the dividing blade 306 and falls evenly from the discharge port on the dividing blade 306 from the discharge hopper 302 to the mold cavity surrounded by the elastic column 201, the elastic sleeve 202 and the first end cover 203, so that the ceramic material is quantitatively and evenly filled into the mold cavity.

[0064] In order to improve the quality of the filler and avoid the excessive gap between the ceramic materials affecting the molding density, in the above process, the controller controls the electric push rod 104 to reciprocate, and the electric push rod 104 drives the vibration plate 105 to reciprocate and collide with the elastic sleeve 202, so that the elastic sleeve 202 vibrates. Under the action of the rotation of the elastic sleeve 202, the vibration plate 105 vibrates different positions of the elastic sleeve 202 evenly and comprehensively, so that the ceramic material in the mold cavity is vibrated. At the same time, in the process of the rotating seat 205 driving the electric telescopic rod 206 and the rotating block 207 to rotate together, the controller controls the electric telescopic rod 206 to reciprocate in the vertical direction, and the electric telescopic rod 206 drives the rotating block 207 to collide with the elastic strip 2013, that is, the elastic plate 2012 and the elastic ring 2011 vibrate when the elastic strip 2013 collides with the rotating block 207. Under the action of force, the elastic column 201 vibrates, thereby vibrating the ceramic material in the mold cavity.

[0065] At the same time, as the height of the ceramic material filled in the mold cavity is increased, the rotating block 207 is adjusted so that the rotating block 207 collides with the elastic strip 2013 at different heights, thereby increasing the vibration intensity of the elastic column 201 at this position. Specifically, the controller controls the electric telescopic rod 206 to extend, and the electric telescopic rod 206 pushes the rotating block 207 to move to this position. Then the controller controls the electric telescopic rod 206 to reciprocate in the vertical direction, and the electric telescopic rod 206 drives the rotating block 207 to collide with the elastic strip 2013 to cause the elastic column 201 to vibrate, thereby increasing the vibration intensity of the elastic column 201 at this position.

[0066] The elastic column 201 is vibrated by the collision of the rotating block 207 and the elastic strip 2013. At the same time, the controller controls the electric push rod 104 to drive the vibration plate 105 to reciprocate and vibrate the elastic sleeve 202, so that the ceramic material between the elastic column 201 and the elastic sleeve 202 is compacted and evenly distributed, thereby reducing defects such as cavities and cracks in the product after molding, improving the molding quality, and avoiding uneven filling during filling, resulting in poor molding density.

[0067] After the filling is completed, the controller turns off the stirring motor 307 and the control valve at the same time to stop the unloading component 3 from working, and then the controller turns off the driving motor to stop the rotating seat 205 from rotating, that is, the elastic mold component 2 is in a stationary state, and then the controller controls the hydraulic rod 209 to contract, and the hydraulic rod 209 drives the block 210 to move away from the rotating seat 205, so that the block 210 is separated from the groove on the surface of the rotating seat 205, and then the ceramic material in the mold cavity is sealed by the second end cover 204, and the sealing cover 103 is placed on the pressurizing cylinder 102 to seal the pressurizing cylinder 102. After the sealing is completed, high-pressure liquid is applied to the pressurizing cylinder 102 to apply pressure to the ceramic material in the elastic mold component 2 to form it.

[0068] In the process of applying high-pressure liquid, since the elastic sleeve 202 and the elastic column 201 are subjected to different pressures at different positions in the initial state, the pressure sensors at different positions detect the pressures at different positions of the elastic ring 2011, and then determine the pressures at different positions of the elastic sleeve 202 and the elastic column 201, specifically:

[0069] If the pressure value detected by the pressure sensor at a certain location exceeds the preset value, it indicates that the elastic ring 2011 at this location is subjected to a greater pressure, that is, it indicates that there is a larger volume of ceramic material at this location. First, the controller controls the electric telescopic rod 206 to extend, so that the electric telescopic rod 206 drives the rotating block 207 to move to the height of this location. Then, the controller turns on the driving motor, and the driving motor drives the electric telescopic rod 206 and the rotating block 207 to rotate together. Under the action of the rotation of the rotating block 207, the rotating block 207 and the elastic strip 2013 are impacted and vibrated. Under the action of force, the larger volume of ceramic material at this location is broken into small pieces. Then, the controller controls the electric telescopic rod 206 to contract, so that the electric telescopic rod 206 drives the rotating block 207 to move below this location. Then, under the action of the rotation of the rotating block 207, the rotating block 207 and the elastic strip 2013 are impacted and vibrated. Therefore, the ceramic material at this location is vibrated, the gap between the ceramic materials is reduced, and local deformation of the molded product is avoided, thereby affecting the molding quality of the product.

[0070] After molding, the high-pressure liquid is discharged, the sealing cover 103 and the second end cover 204 on the molding component 1 are opened, and then demolding is performed. Since the molded product is easy to adhere to the elastic column 201 during demolding, manual demolding is easy to cause surface damage to the molded product. Therefore, during demolding, the controller first turns on the drive motor, and the drive motor drives the rotating seat 205, the electric telescopic rod 206 and the rotating block 207 to rotate together. At the same time, the controller controls the electric telescopic rod 206 to reciprocate, so that the rotating block 207 continuously collides with the elastic strip 2013 in the vertical direction. Under the action of force, the elastic column 201 vibrates, so that the outer surface of the elastic column 201 and the inner wall of the molded product are vibrated and separated.

[0071] Then the driving motor is controlled and turned off to stop the rotating seat 205 from rotating and to make the electromagnetic plug at the position of the rotating block 207 correspond to the socket 211 inside the elastic column 201. Then the controller controls the electric telescopic rod 206 to retract, and the electric telescopic rod 206 drives the rotating block 207 to move toward the direction close to the socket 211, so that the rotating block 207 is at the bottom of the elastic column 201. Then the controller controls the electromagnetic plug to be energized so that the electromagnetic plug is inserted into the socket 211 for fixing. Then the controller turns on the driving motor, and the driving motor drives the rotating seat 205, the electric telescopic rod 206, and the rotating block 207 to move toward the socket 211. The movable block 207 and the elastic column 201 rotate together, and the first end cover 203 and the elastic sleeve 202 are limited by the support base 208 at this time. The elastic column 201 is rotatably connected with the first end cover 203, that is, the first end cover 203, the elastic sleeve 202 and the molded product are stationary. Then, under the action of the rotation of the elastic column 201, the adhesion between the outer surface of the elastic column 201 and the inner wall of the molded product is rotated and separated. At the same time, the controller controls the electric telescopic rod 206 to extend, and the electric telescopic rod 206 drives the rotating block 207 and the elastic column 201 to move upward as a whole, so that the elastic column 201 is taken out.

[0072] Since the molded product is not easy to take out under the combined action of the elastic column 201 and the elastic sleeve 202, the elastic column 201 is taken out at this time, and the force of the elastic column 201 on the molded product disappears, thereby facilitating the removal of the molded product.

[0073] In addition, the controller controls the electric push rod 104 to reciprocate, and the electric push rod 104 drives the vibration plate 105 to reciprocate and collide with the elastic sleeve 202, thereby causing the elastic sleeve 202 to vibrate, effectively further separating the molded product from the elastic sleeve 202, thereby making it easier to take the molded product out of the elastic sleeve 202.

[0074] The present invention discloses a molding method for a molding device, and the specific molding method steps are as follows:

[0075] S1: First, open the molding assembly 1 and place the elastic mold assembly 2 in the pressurizing cylinder 102;

[0076] S2: Next, the second end cover 204 is opened, and then ceramic material is added into the elastic mold assembly 2 through the blanking assembly 3, and after the filling is completed, it is sealed through the second end cover 204;

[0077] S3: then closing the molding assembly 1 to make the pressurizing cylinder 102 in a sealed state, and then applying high-pressure liquid to the pressurizing cylinder 102 to apply pressure to the ceramic material in the elastic mold assembly 2 to form it;

[0078] S4: Finally, the high-pressure liquid is discharged after molding, and then the molding component 1 is opened to take out the product molded in the elastic mold component 2.

[0079] The application of a molding device in a ceramic ring disclosed in the present invention is specifically used for isostatic pressing of the ceramic ring during the production and processing process. The incompressible property of the liquid medium and the property of uniformly transmitting pressure are utilized to uniformly pressurize the ceramic material in the elastic mold assembly 2 from all directions to form it. The advantages are high density, good quality, and not easy to deform.
