The invention discloses an isostatic pressing forming method and forming mold for
ceramic roller bars, and relates to the field of isostatic pressing forming. The isostatic pressing forming mold comprises a bottom plate, a feeding
assembly, an outer mold, an inner mold, a pressurizing
assembly, a movable block, a pushing
assembly, a fixed block, a first hydraulic bag, a second hydraulic bag, an
exhaust pipe and feeding pipes, wherein the feeding assembly is mounted at one end of the top side of the bottom plate, the fixed block is installed on the top side of the bottom plate, the movable block is installed on the pushing assembly, and the inner mold is fixedly connected to the movable block. Through the arrangement of the feeding assembly, materials in a material hopper enter a feeding cylinder through a material guiding
pipe, when a
piston disc descends, the materials are discharged through discharging pipes, under the cooperation of six feeding pipes, filling of the materials can beachieved; the gap between the outer mold and an inner mold can be filled, through one-way injection material filling,
gas mixing is reduced, the gas content is reduced, the compactness of blanks is improved, and through guide-in and synchronous filling of the six discharging pipes arranged in a surrounding mode, uneven material filling is avoided, and filling is more balanced.
