Ceramic pressing die, pressing device and ceramic production process applying device

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...

Problems solved by technology

[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
