Then continue to drive the bottom box to move to the other side. By moving the bottom box, the pressed ceramic is pushed to the surface of the extension plate. Then drive the hydraulic cylinder to reset the demolding plate, and then drive the bottom box to move for feeding to perform the next pressing operation, so as to achieve no need for manual feeding and avoid the problems of easy pollution and waste caused by the powder being exposed outside.

[0016] In the present utility model, for the ceramic uniform pressing and forming device, through the feeding assembly, it can achieve storing the ceramic powder in the interior of the bottom box, thereby avoiding the risk that the powder is exposed outside and easily drifts into the air, causing waste and being inhaled by the staff. And through the drive of the servo motor, automatic feeding can be realized, thus replacing the original workload of manual labor.

[0017] In the present utility model, for the ceramic uniform pressing and forming device, through the demolding assembly, after the ceramic is pressed into shape, it can achieve pushing it out to complete demolding by controlling the demolding plate to move upward, and the ceramic can be directly pushed out of the pressing range during subsequent feeding.

[0018] In the present utility model, during use, through the feeding assembly, automatic feeding can be realized, and the ceramic powder can be restricted inside the bottom box, avoiding the risk that the powder is exposed outside and easily drifts into the air, causing waste and being inhaled by the staff.
