[0007] Its advantages are: it can realize continuous rolling, produce bricks of unlimited length, and has low energy consumption; but its disadvantages are: it is conveyed by steel belt, and the steel belt is easily deformed by external force collision, which affects the quality of rolling formed bricks; roll forming It is subject to linear pressure, the pressing area is small, the powder is easy to flow during the pressing process, and it is impossible to produce ultra-thin ceramic plates
[0011] In this way, since the floating mold frame is lowered, the inlays are directly pressed on the belt and frame the powder. The inlays are steel parts, and the pressure area of the belt is small. After repeated pressing, the belt is easily damaged and the service life is reduced. short

Embodiment 1
[0064] refer to figure 1 , figure 2 , this embodiment discloses a ceramic pressing device, comprising a press 1, a ceramic pressing mold 2 and a conveyor belt 3, the ceramic pressing mold 2 is arranged in the press 1, and the press 1 adopts a hydraulic brick press in the prior art , including a fixed seat 101 and a moving beam 102, driven by a hydraulic cylinder, the moving beam 102 can be lifted vertically relative to the fixed seat 101, and the conveying belt 3 passes through the press 1 for sending the powder 4 into the press 1 in the ceramic pressing mold 2, and the pressed adobe is delivered out of the press 1.
[0065] refer to Figure 1 to Figure 7 The ceramic pressing mold 2 includes a magnetic plate 201, an upper mold core 202, and a lower template 203. The upper mold core 202 is magnetically adsorbed and fixed on the magnetic plate 201, and the lower template 203 is located directly below the upper mold core 202. The lower template 203 is connected to the upper mo...
Embodiment 2
[0077] Based on Embodiment 1, this implementation discloses a ceramic production process, using the ceramic pressing device in Embodiment 1, comprising the following steps:
[0078]Step 1: Blanking and feeding: spread the powder on the conveyor belt, and the conveyor belt will send the ceramic powder into the center of the press, and make the ceramic powder be located directly under the upper core of the ceramic pressing mold, and the conveyor belt will stop;
[0079] Step 2: Pressing: the moving beam of the press moves down to press, and the powder is formed in the cavity;
[0080] When pressing, at least one low-pressure pressing step, one medium-pressure pressing step, and one high-pressure pressing step are performed. The low-pressure pressing step and the middle-pressure pressing step both include a moving beam downward pressing process and a moving beam upward moving exhaust process; low-pressure pressing step, medium pressure pressing step, and high pressure pressing st...

Abstract
The invention discloses a ceramic pressing die, a pressing device and a ceramic production process applying the device, and relates to the field of ceramic production. The ceramic pressing die comprises a magnetic attraction plate, an upper die core and a lower die plate, the upper die core is magnetically attracted and fixed to the magnetic attraction plate, the lower die plate is located under the upper die core, and flexible blocking strips are arranged on the surface, deviating from the magnetic attraction plate, of the upper die core; a cavity is defined by the flexible blocking strips onthe surface of the upper die core, flexible pre-pressing bosses are further arranged on the surface of the upper die core, the flexible pre-pressing bosses and the flexible blocking strips are arranged in a spaced mode, the flexible pre-pressing bosses are located in the cavity, and the distance between the flexible blocking strips and the surface of the upper die core is larger than that betweenthe flexible pre-pressing bosses and the surface of the upper die core. The hardness of the flexible pre-pressing bosses is larger than that of the flexible blocking strips. According to the ceramicpressing die, the ceramic pressing device and the ceramic production process, compared with an existing rigid die frame, damage to a conveying belt can be effectively reduced, and therefore the service life of the whole ceramic pressing die is prolonged, the maintenance frequency is reduced, and the pressing reliability is enhanced.
Description
technical field [0001] The invention relates to the field of ceramic production, in particular to a ceramic pressing mold, a pressing device and a ceramic production process using the device. Background technique [0002] At present, there are four kinds of molding methods for large-scale ceramic plates (more than 2 meters) at home and abroad. The first type: the large-tonnage press of about 10,000 tons mainly adopts the mature traditional lower mold frame pressing brick mold horizontal pressing molding method, specifically , you can refer to the patent application with the application number 201010293448.9, the feeding car is connected to the back of the press, and the feeding system arranges the ceramic powder in the grid of the feeding car, and then pushes it forward, and the pressed brick is pushed to the conveying line , while pushing out the pressed adobe, the powder in the grid is sent to the mold of the press, the powder in the grid is filled into the cavity, and the...
