Technical Field

[0001] The invention belongs to the technical field of ceramic processing, in particular to a ceramic blank mold dry pressing forming device. Background Art

[0002] Dry pressing is a commonly used green body forming method in ceramic production. The powder is granulated with a small amount of binder, then loaded into a mold and pressurized on a press so that the powder particles are close to each other in the mold and firmly combined by internal friction to form a green body of a certain shape. Conventional methods include unidirectional pressing, bidirectional pressing, and four-directional pressing. Improved dry pressing includes vibration pressing and magnetic field pressing, among which magnetic field pressing is suitable for metal powders.

[0003] When pressing ceramic powder, it is necessary to fill the container with ceramic powder and then apply pressure, but the following problems may occur:

[0004] 1. In order to ensure sufficient powder volume, ceramic powder is usually filled in excess at a single time, which results in more and more powder gradually accumulating on the working plane during continuous processing, resulting in cost waste and serious contamination of the formed ceramic products;

[0005] 2. During the dry pressing process, the gas squeezed out from the inside of the container will produce gas pits on the surface of the blank. In serious cases, the blank structure is not strong and is easy to break, which will lead to the problem of blank scrapping. Summary of the invention

[0013] The beneficial effects of the present invention are as follows:

The device can use the unique feeding method of the feeding equipment to smooth the powder remaining on the upper surface of the shaping inner plate after each time the blank is pushed out from the inclined plate, thereby solving the problem of gradual accumulation of powder on the upper surface of the shaping inner plate. Since the inner push bottom plate can slide downward with the pressure during pressurization, the powder filling the receiving port will not overflow to the outside during the extrusion process, avoiding the problem of insufficient material and defective molded blanks.

[0015] 2. The device uses a composite sleeve to pressurize the accommodating port. Since the composite sleeve is directly pressed on the upper surface of the shaping inner plate through the sliding downward sleeve at the bottom, it ensures that the shaping cover can be accurately inserted into the shaping port. Therefore, during the extrusion process of the shaping inner plate, the buffering effect of the downward pressing inner tube and the spring washer tube can reduce the extrusion force on the shaping inner plate, thereby avoiding the problem of pressure deformation of the shaping inner plate.

[0016] 3. After the scraping work of the feeding equipment, only a layer of fine powder particles will remain on the upper surface of the shaping inner plate. Therefore, these fine particles can be absorbed into the interior of the suction inner cylinder during the downward pressing process through the suction device inside the extended bottom cylinder, thereby achieving the effect of recycling and cleaning. In addition, the bottom end of the downward pressing inner cylinder is thinner and will not cover a larger area of ​​the upper surface of the shaping inner plate, thereby avoiding the problem of poor cleaning effect of the shaping inner plate due to covering problems.

[0017] 4. When extracting powder through the bending tube, the control motor drives the rotating ring cover to rotate around the lower surface of the suction inner cylinder by rotating the top wheel, thereby ensuring that there are no dead angles in the extraction range of the suction equipment, and ensuring that the extraction force is relatively uniform, and a large area on the upper surface of the shaping inner plate is comprehensively cleaned.

[0028] The shaping component 1 includes a control base 11, which can push the vertical push rod at the axis up and down, and the outer surface of the vertical push rod is sleeved with a pressure washer 13, which cannot be compressed after being squeezed to a certain extent; a side outer frame 12, the bottom of the side outer frame 12 is fixedly connected to the upper surface of the control base 11, and the side outer frame 12 is made of iron metal material; a shaping inner plate 15, the outer surface of the shaping inner plate 15 is fixedly connected to the middle of the inner wall of the side outer frame 12, and a receiving opening is opened at the axis of the inner cavity of the shaping inner plate 15, and the size of the receiving opening is adjusted according to the shape of the pressed ceramic; an inner push bottom plate 14, the outer surface of the inner push bottom plate 14 is slidably connected to the inner wall of the shaping inner plate 15 through the receiving opening, and the axis of the inner cavity of the inner push bottom plate 14 is fixedly connected to the axis of the control base 11 through the vertical push rod, and the inner push bottom plate 14 is supported by the pressure washer 13 to share the downward pressure for the control base 11.

[0029] The feeding device 2 includes: a feeding box 21, the bottom of which is fixedly connected to the ground, and an inlet for inputting ceramic powder is provided on the back of the feeding box 21; a vertical slide 22, the bottom of the outer surface of the vertical slide 22 is slidably connected to the axis of the inner wall of the feeding box 21; a horizontal traction rod 23, the left end of the horizontal traction rod 23 is fixedly connected to the top of the inner wall of the vertical slide 22; a sliding inner box 24, the axis of the upper surface of the sliding inner box 24 is fixedly connected to the right end of the horizontal traction rod 23; a buckled inner cover 25, the axis center of the top of the inner cover 25 is fixedly connected to the inner cavity of the horizontal traction rod 23 through a connecting hose; the outer sliding frame 26, the inner wall of the outer sliding frame 26 is slidably connected to the outer surface of the sliding inner box 24, and the front and rear sides of the lower surface of the outer sliding frame 26 are slidably connected to the upper surface of the side outer frame 12 through the adsorption roller 27, the adsorption roller 27 can slide horizontally along the edge position of the upper surface of the side outer frame 12, and the sliding inner box 24 can move relative to the inner wall of the outer sliding frame 26.

[0030] The pressurizing component 3 includes a downward pressing traction rod 31, the top of which is fixedly connected to the ceiling; a composite sleeve 32, the axis of the upper surface of the composite sleeve 32 is fixedly connected to the bottom end of the downward pressing traction rod 31; a shaping pressure rod 4, and the shaping pressure rod 4 is arranged at the axis of the composite sleeve 32; a suction device 5, which can suck away the ceramic powder remaining on the upper surface of the shaping inner plate 15 to achieve a cleaning effect.

[0031] Before using the device to press the ceramic ligand, first lift the composite sleeve 32 upward by pressing the traction rod 31 downward, and then the feeding device 2 pushes the sliding inner box 24 to the right through the horizontal traction rod 23, and the outer sliding frame 26 assists in sliding through the adsorption roller 27 at the bottom. Then, after reaching the position just above the inner push bottom plate 14, the feeding box 21 pulls the vertical slide 22 downward so that the buckled inner cover 25 is buckled on the opening at the axis of the shaping inner plate 15, and then the ceramic powder is drawn into the top of the inner push bottom plate 14 through the vertical slide 22 to fill the axis of the shaping inner plate 15, and then stop feeding, and directly use the horizontal traction rod 23 to pull the sliding inner box 24 to the left. Since the buckled inner cover 25 is in contact with the upper surface of the shaping inner plate 15 at this time, the buckled inner cover 25 will take away the excess ceramic powder near the shaping mouth of the shaping inner plate 15 when moving, thereby ensuring that the poured powder just fills the shaping mouth of the shaping inner plate 15.

[0032] When the pressure-applying component 3 is working, the downward pressing traction rod 31 pushes the composite sleeve 32 downward so that the shaping pressure rod 4 is inserted into the shaping mouth. At this time, the composite sleeve 32 and the upper surface of the shaping inner plate 15 squeeze each other, and then the shaping pressure rod 4 actively pushes downward relative to the composite sleeve 32, thereby pressurizing the ceramic powder inside after shaping. Then, the inner push bottom plate 14 will slide down a distance due to the pressure by pressing the pressure washer 13, reserving a certain amount of space for the extruded ceramic powder, and then the pressure washer 13 is shaped, and then the ceramic powder is successfully shaped under the action of high pressure. After the shaping pressure rod 4 is pulled out, the control base 11 pushes the inner push bottom plate 14 upward to push the formed blank out of the inside of the shaping mouth, and then the next time the outer sliding frame 26 is pushed horizontally, the blank above the inner push bottom plate 14 is pushed out from the slope on the right, and then the inner push bottom plate 14 is pulled back to the initial position, and the blank dry pressing work is cyclically performed.

[0033] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of the first embodiment, the composite sleeve 32 comprises an outer cylinder shell 321, the axis center of the top of the outer cylinder shell 321 is fixedly connected to the bottom end of the downward traction rod 31; an upper sliding sleeve 323, the side of the upper sliding sleeve 323 is slidably connected to the inner wall of the outer cylinder shell 321, and the top of the inner cavity of the upper sliding sleeve 323 is fixedly connected to the axis center of the inner wall of the outer cylinder shell 321 through the elastic pull cylinder 322; a downward pressing sliding sleeve 324, a lower The side of the pressing sleeve 324 is slidably connected to the bottom of the inner wall of the outer cylinder shell 321 through a spring washer tube 325; the pressing inner cylinder 326 is pressed down, and the number of the pressing inner cylinders 326 is ten. The top of the pressing inner cylinder 326 is fixedly connected to the inner wall of the pressing sleeve 324, and the bottom end of the pressing inner cylinder 326 extends to the outside of the pressing sleeve 324. The axis of the bottom end of the pressing inner cylinder 326 is provided with a slidable rod body, and the pressure exerted on the rod body is fed back to the pressing inner cylinder 326.

[0034] The shaping pressure rod 4 includes a torsion motor 41, the upper surface of which is fixedly connected to the axis of the top of the inner wall of the outer cylinder shell 321; a slide slot rod 42, the axis of the top of the slide slot rod 42 is fixedly connected to the outer surface of the output shaft of the torsion motor 41; a receiving drum 43, the inner wall of the receiving drum 43 is slidably connected to the outer surface of the slide slot rod 42, and the outer surface of the receiving drum 43 is rotatably connected to the axis of the inner wall of the upper sliding sleeve 323, and when the slide slot rod 42 rotates, it can drive the receiving drum 43 to rotate synchronously; a threaded propulsion rod 44, the top of which is fixedly connected to the axis of the bottom of the receiving drum 43 The bottom end of the threaded push rod 44 is fixedly connected with a shaping cover 49; an extended bottom cylinder 48, the outer surface of the extended bottom cylinder 48 is slidably connected to the bottom of the inner wall of the downward pressing sleeve 324; a control ring 46, the outer surface of the control ring 46 is fixedly connected to the axis of the upper surface of the downward pressing sleeve 324, and the inner cavity of the control ring 46 is evenly provided with a booster push rod 47, and the bottom end of the booster push rod 47 is fixedly connected to the upper surface of the accommodating rotating cylinder 43; a threaded sleeve 45, the outer surface of the threaded sleeve 45 is fixedly connected to the axis of the inner cavity of the downward pressing sleeve 324, and the outer surface of the threaded push rod 44 is threadedly connected to the inner wall of the threaded sleeve 45.

[0035] The suction device 5 includes an air suction inner cylinder 51, the upper surface of which is fixedly connected to the top of the inner wall of the extended bottom cylinder 48; a rotating ring cover 52, the upper surface of which is rotatably connected to the bottom of the air suction inner cylinder 51, and the inner cavity of the rotating ring cover 52 is evenly provided with bent through tubes 53; a filling bottom ring 54, the inner cavity of the filling bottom ring 54 is fixedly connected to the bottom end of the bent through tube 53 through a through opening, and the outer surface of the filling bottom ring 54 is rotatably connected to the bottom of the inner cavity of the extended bottom cylinder 48 through an annular cut groove; a control motor 55, the top end of the output shaft of the control motor 55 is rollingly connected to the inner wall of the rotating ring cover 52 through a rotating wheel.

[0036] When the pressurizing component 3 is inserted into the side outer frame 12, the pressing sleeve 324 at the bottom of the outer cylinder shell 321 is first squeezed against the upper surface of the shaping inner plate 15 through the pressing inner cylinder 326, and then the torsion motor 41 drives the threaded pushing rod 44 to push downward clockwise around the threaded sleeve 45 by rotating the accommodating rotating cylinder 43, pressing the shaping cover 49 into the shaping port to achieve the pressurization effect.

[0037] When the shaping work is performed, the control ring 46 pushes the extension bottom cylinder 48 downward through the force push rod 47. At this time, the position of the bottom notch of the extension bottom cylinder 48, that is, the position of the filling bottom ring 54 is moved to the edge of the shaping port, and then the suction inner cylinder 51 absorbs the powder particles at the side of the accommodating port through the bending tube 53 to achieve the cleaning effect. Since the rod body at the axis of the pressing sleeve 324 itself has a certain elastic coefficient, the bottom of the composite sleeve 32 is not completely covered with the upper surface of the shaping inner plate 15, so the attraction of the bending tube 53 will directly act on the upper surface of the shaping inner plate 15, so as to achieve a larger range of cleaning effect, and the bottom end of the pressing inner cylinder 326 is thinner and will not cover a larger range of the upper surface of the shaping inner plate 15.

[0038] When the bent tube 53 is used to extract powder, the control motor 55 drives the rotating ring cover 52 to rotate around the lower surface of the suction inner cylinder 51 by rotating the top wheel, thereby ensuring that there are no dead angles in the extraction range of the suction device 5 and ensuring that the extraction force is relatively uniform.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
