The invention discloses a method for isostatic pressing of a ceramic roller bar and a forming mould thereof, and relates to the field of isostatic pressing, comprising: a bottom plate, a feeding component, an outer mould, an inner mould, a pressing component, a movable block, a pushing component, a fixing Block, the first hydraulic bladder, the second hydraulic bladder, the exhaust pipe and the feed pipe, a feeding assembly is installed on one end of the top side of the bottom plate, a fixed block is mounted on the top side of the bottom plate, and the movable block is mounted on the pusher. On the assembly, the inner mold is fixed on the movable block. By setting the feeding assembly, the material in the material hopper enters the feeding barrel through the material guide pipe. When the piston disc descends, the material is discharged through the discharge pipe. With the cooperation of the material tube, the material can be filled, and the gap between the outer mold and the inner mold can be filled. Through one-way injection of the filler, the mixing of gas can be reduced, the gas content can be reduced, and the density of the blank can be improved. Six discharge pipes are introduced and filled synchronously to avoid uneven filling and more balanced filling.
Description
technical field [0001] The invention relates to the field of isostatic pressing, in particular to an isostatic pressing forming method of a ceramic roller and a forming mold thereof. Background technique [0002] Isostatic pressing is to place the sample to be pressed in a high-pressure container, and use the incompressible properties of the liquid medium and the properties of uniform pressure transmission to uniformly pressurize the sample from all directions. When the liquid medium is injected into the pressure vessel through the pressure pump , according to the principle of fluid mechanics, the pressure is constant and uniformly transmitted to all directions. At this time, the pressure on the powder in the high-pressure container is uniform and consistent in all directions. The method of forming a dense green body from barren powder by the above method is called isostatic pressing; [0003] In the process of isostatic pressing, it is usually formed by hydraulic extrusion...
