In the practical ceramic production activity, the models need to be carried and placed manually in the existing ceramic disc product production line, the weight of a single model is about 30kg on average, the operation intensity of workers is high, the working efficiency is low, and the working environment is relatively severe. In the production process, a worker needs to move the model 3 times (the model is placed on the grouting table, the model is taken down from the grouting table after grouting forming and placed on the operating table, the model is opened and placed on the grouting table again), the model is repeatedly moved, and the labor intensity is extremely high. Meanwhile, in the existing low-pressure grouting, the product forming time needs about 0.5 hour to complete a production cycle, workers need to time by themselves, the blank forming time can also change along with the change of the dryness and humidity of the model, the workers need to judge the forming time according to experience, certain requirements are required on the technical level of the workers, and the standardized production is not facilitated. And workers occasionally make a judgment error, open the mold early, the blank is not molded, and some of the blank is molded by demolding at that time, but the molding is not completed inside, the blank is seriously deformed, and a problem is found after firing, so that more loss is caused. The mold is opened late, the production efficiency is influenced, the blank begins to shrink after being formed in the mold, and the blank directly cracks in the mold, so that the yield is low. Even if the mold opening time is reasonably controlled, the water content of the green body is higher when the low-pressure grouting product is demolded, and the green body is still in a soft state without being shaped. The workman need utilize the layer board, takes out the product from the model, and this operation needs high proficiency, is unfavorable for the popularization of production, enlarges production.

The working principle is as follows: the raw material of the grouting mud is manually injected into the low-speed mud stirring barrel 37, and the density and the proportion of the grouting mud are finely adjusted in the mud barrel body 29, so that the grouting mud can be used for high-pressure grouting forming. Meanwhile, the low-speed slurry stirring barrel 37 is continuously rotated and stirred to prevent the slurry from being deeply deposited.

The diaphragm pump 27 in the low-pressure slurry supply system 38 extracts slurry from the low-speed slurry mixing tank 37, conveys the slurry to the slurry conveying cavity 23 in the liquid medium-slurry pressure converter 42, conveys the slurry to the inner cavity of the mold which is closed after the slurry is filled through the slurry outlet of the slurry conveying cavity 23, closes the first air-controlled ball valve after the filling time (which can be set through a PLC in an electric control cabinet), and stops conveying the slurry to the liquid medium-slurry pressure converter 42, but the liquid medium-slurry pressure converter 42 is still communicated with the inner cavity of the mold, namely the slurry outlet of the liquid medium-slurry pressure converter 42 is still communicated with the inner cavity of the mold.

The hydraulic station 28 operates to start pressurizing the hydraulic oil in the hydraulic oil chamber 15 in the oil-liquid medium pressure converter 41, while the hydraulic station 28 is filling the hydraulic accumulator 43 with pressure. After the hydraulic oil in the oil-liquid medium pressure converter 41 reaches a certain pressure value, the electromagnetic valve which controls the hydraulic station 28 to be communicated with the oil-liquid medium pressure converter 41 is powered off, the hydraulic station 28 does not provide power for the oil-liquid medium pressure converter 41 any more, and the follow-up pressure in the oil-liquid medium pressure converter 41 is kept to be provided by the hydraulic accumulator 43.

The oil-liquid medium pressure converter 41 transmits the pressure of the hydraulic oil to the liquid medium 22 in the liquid medium cavity 19, the pressure in the liquid medium 22 is increased to the set mud pressure (4Mpa), and the liquid medium 22 transmits the pressure to the mud in the liquid medium-mud pressure converter 42 through the liquid medium-mud pressure converter 42, so that the mud reaches the set pressure. The slurry in the fluid medium-to-slurry pressure transducer 42 is connected to the slurry in the mold and pressure is also transmitted to the slurry in the mold.

Due to the existence of high pressure, the moisture in the slurry is accelerated to enter the porous resin mold, the moisture is discharged out of the mold through a capillary network in the porous resin mold, the moisture content of the slurry in the mold is rapidly reduced, and after the slurry reaches a certain moisture content (the moisture content of a green body is not directly measured but is controlled by pressurization time because the slurry performance, the pressurization pressure and the mold performance are consistent), the slurry is changed into a mud blank with a certain shape under the action of the mold.

After the forming is finished, the second pneumatic control ball valve between the liquid medium-slurry pressure converter 42 and the stirring barrel is opened, then the die, the liquid medium-slurry pressure converter 42 and the low-speed slurry stirring barrel are communicated, and the pressure in the die and the pipeline is released.

After the piston rod of the rotary oil cylinder 9 retracts to the lowest position, the main oil cylinder 8 is closed to completely avoid the activity space of the support shaft 13.

And the electromagnetic valve for controlling the communication of the compressed air and the left side die 11 is electrified, the compressed air enters the left side die 11, and the die is separated from the product through the resin capillary holes. After a certain time of ventilation, the speed reducing motor 4 connected with the crank 5 starts to work, the speed reducing motor drives the crank 5 to act, the crank 5 drives the connecting rod 7 to act, the connecting rod 7 drives the left die to start to move leftwards, and finally the left die reaches the left limit point of the crank 5, so that the die opening action is completed, as shown in fig. 5.

The safety door is opened, the product blank is manually taken out of the right side die 12 by using the sucker clamp, and the safety door is closed.

After the product is taken out, electric self-priming pump 47 starts, and the clear water gets into filter 48 from the self-priming pump, and in the water pipe got into the mould of both sides again, the capillary micropore through the resin mold discharged from the shaping working face of mould, the completion was to the washing of mould working face. After a certain time of cleaning, the electric self-priming pump 47 is turned off.

After the die working surface is cleaned, the die air cleaning system 46 controls the compressed air to be electrified with the electromagnetic valves communicated with the dies on the two sides, and the compressed air enters the dies on the two sides and discharges the moisture in the resin capillary holes.

After the mold is drained, the speed reducing motor 4 connected with the crank 5 starts to work again, but the rotating direction of the speed reducing motor 4 is opposite to that before, the speed reducing motor 4 drives the crank 5, the crank 5 drives the connecting rod 7, the connecting rod 7 drives the mold on the left side to start to move rightwards, and finally the right limit point of the crank 5 is reached, the piston of the rod end cylinder 14 at the end part of the connecting rod 7 extends out, the molds on the left side and the right side are pressed together, and the mold closing action is completed.

And the piston rod of the rotary oil cylinder 9 extends out to push the closed main oil cylinder 8 to a closed jacking position, and after the piston rod of the rotary oil cylinder 9 reaches an upper limit position, the piston rod of the closed main oil cylinder 8 is just concentric with the support shaft 13 on the left side of the mold.

After the closed main oil cylinder 8 reaches the closed jacking position, the piston rod extends out to be in contact with the supporting shaft 13, and meanwhile, the mould is jacked. The tail part of the closed main oil cylinder 8 is attached to the left upright post 3, the closed main oil cylinder 8 keeps the piston rod extending thrust, and mold clamping force larger than or equal to 100 tons is provided for the mold.
