Description

[0002] At present, the production forming process of ceramics mainly has three kinds of rolling, high-pressure grouting and hollow grouting, among which the high-pressure grouting process is applied most, and at present, the high-pressure grouting of ceramic forming mold mostly uses the pressurizing mode of high-pressure tank, which gives the ceramic slurry a propelling force, but due to the very large high-pressure tank body, considering the safety factor and the compression resistance of the gypsum mold, the pressure in the high-pressure tank is generally 0.15-0.2MPa. And the ceramic produced by such pressure will have many problems.

[0003] Due to the insufficient pressure in the inner cavity of the gypsum mold, it will cause the ceramic slurry to shrink (for example, the bottom of the ceramic square or oval plate has a ring foot, and the front of the plate will have several visible concave marks), the slurry line is obvious (in order to increase the fluidity of the slurry, chemical additives are added in the ceramic production process, causing the density of the slurry in this part to be higher, and the ceramic product will have a convex joint line), water ripples (due to low pressure, the slurry slowly and intermittently pushes in the mold cavity, leaving marks), these factors will eventually be more obvious in the finished product, and the finished product quality is low. In addition, the forming time of a single product is 40 minutes on average, and the production efficiency is low. SUMMARY

[0032] Working principle of this invention:

[0033] Continue to refer to Figures 1 to 8 As shown, the number of workbenches 2 is at least one, and the number can be freely set according to the actual use, without any limitation. In one embodiment, two workbenches 2 are set, and the two workbenches 2 are set in parallel, so that the mold 5 can be subjected to high-pressure grouting at the same time or alternately, thereby improving work efficiency. In one embodiment, the booster pump can be a pneumatic diaphragm pump, an electric booster pump, or other pressurizing devices. The grout inlet of the booster pump is connected to the mud storage tank, and the grout outlet of the booster pump is connected to the grouting port 6 opened on the top of the work frame 1.

[0034] In operation, first, a plurality of molds 5 to be grouted are stacked on the transfer table 4, and when the molds 5 are stacked, the grouting holes 51 of each mold 5 are aligned with the grouting holes 51 of the adjacent mold 5; then, under the drive of the transmission mechanism 8, the transfer table 4 is driven to translate so that the mold 5 is located directly below the top plate 12 (so that the grouting hole 51 of the mold 5 is aligned with the grouting port 6); then, the first lifting mechanism 3 drives the workbench 2 to drive the transfer table 4 to rise until the mold 5 at the topmost layer is attached to the bottom surface of the top plate 12 (by applying a jacking force through the first lifting mechanism 3, the mold 5 can be fixed in position between the transfer table 4 and the top plate 12), and at the same time that the mold 5 is attached to the bottom surface of the top plate 12, the grouting hole 51 is aligned and communicated with the grouting port 6; then, the booster pump starts to automatically boost (in an embodiment, a solenoid valve is further connected between the booster pump and the grouting port 6, and after the solenoid valve is opened, the booster pump starts to boost), thereby pushing the mud into the mold 5 through the grouting port 6 and the grouting hole 51 (in an embodiment, the mold 5 is also provided with a flow guide groove 52 and a flow guide port 53, which can play a mud flow guiding role), after the set boosting time arrives, the solenoid valve is closed, the first lifting mechanism 3 drives the workbench 2 to reset, the transfer table 4 translates the mold 5 to the outside, and after the staff takes it out, the mold 5 is re-placed, and the cycle is repeated. In this embodiment, the mechanical boosting method can increase the pressure to 0.5 MPa or higher, and in the case of higher pressure, the mud pushing speed is fast, thereby avoiding the formation of grout lines, shrinkage, water ripples and other marks, improving product quality, and at the same time, since the grouting holes 51 of the molds 5 are aligned and communicated with each other, high-pressure grouting work of multiple molds 5 can be realized at one time, greatly improving the work efficiency. Specifically:

[0035] In an embodiment, the working stand 1 includes a base 11 and a top plate 12, and a plurality of lifting guide rods 13 are connected between the base 11 and the top plate 12. In this embodiment, a linear bearing 21 is arranged at each corner of the workbench 2, and each linear bearing 21 is mounted on a lifting guide rod 13. When the first lifting mechanism 3 drives the workbench 2 to rise and fall, it can be guided to ensure the stability of the lifting; the first lifting mechanism 3 includes a first hydraulic cylinder 33, and a hydraulic pump assembly 14 connected with the first hydraulic cylinder 33 is also mounted on the base 11. The hydraulic cylinder can provide sufficient jacking force for the workbench 2; in an embodiment, the transfer table 4 can move relative to the workbench 2 to place or take out the mold 5, such as Figure 2As shown, in this embodiment, a position sensor is also installed at one end of the top of the guide rail frame 43. After the mold 5 is stacked on top of the transfer table 4 (at this time, the transfer table 4 is in a state of extending outward from the work frame 1 to pick up and put down the mold 5), the second hydraulic cylinder 81 drives the first lifting plate 82 to rise, so that the transmission gear 84 meshes with the transmission rack 41. Subsequently, the servo motor 83 starts, and drives the transfer table 4 to move into the work frame 1 through the transmission gear 84 and the transmission rack 41 (the four corners of the bottom of the transfer table 4 are provided with pulleys 42, which can roll on the guide rail frame 43 to improve the smoothness of its translational movement). When the transfer platform 4 moves into position (so that the mold 5 is directly below the top plate 12 and the grouting hole 51 of the mold 5 is aligned with the grouting port 6), the material sensor detects the positioning signal, and the background control servo motor 83 stops running. Then, the second hydraulic cylinder 81 drives the first lifting plate 82 to descend, so that the transmission gear 84 disengages from the transmission rack 41. The first lifting mechanism 3 drives the worktable 2 to rise to perform the grouting action. After the mold 5 is grouted, the servo motor 83 moves the transfer platform 4 from inside the work frame 1 to the outside. The translation process is the reverse of the above and will not be described in detail here.

[0036] like Figures 6-7 As shown, in one embodiment, a top cleaning mechanism 9 is also installed on the top plate 12. After a high-pressure grouting operation is completed, the residual mud on the bottom surface of the top plate 12 can be cleaned to ensure that the bottom surface of the top plate 12 is clean and tidy. During operation, the second translation cylinder 100 drives the cleaning slide plate 98 to rise so that the cleaning scraper 102 contacts the bottom of the top plate 12. Then, the first translation cylinder 94 drives the first slide plate 93, which moves the cleaning scraper 102 left and right through the profile frame 95 and the cleaning fixing seat 96. The cleaning scraper 102 scrapes off the mud remaining on the bottom of the top plate 12, and the scraped mud falls into the recycling box. Inside the recycling box 99, the mud can be sucked out by an external recycling mechanism for recycling. In this embodiment, the recycling box 99 is hollow inside and has openings of different diameters at both ends. It is funnel-shaped. The larger opening of the recycling box 99 is arranged towards the bottom of the top plate 12, and the end face of the opening is parallel to the bottom surface of the top plate 12 to catch all the scraped mud and prevent the mud from scattering to other places. At the same time, one end of the recycling box 99 is inclined upward, so that the mud can flow smoothly into the external recycling mechanism through the recycling interface 101 under the action of gravity, thus preventing the recycling box 99 from being blocked.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
