An embodiment of the present invention provides a cold isostatic pressing complex mold comprising: a first mold to be filled with granular alumina powder, having elasticity; and a perforated second mold arranged to envelop an exterior of the first mold, supporting the first mold having a plurality of through-holes formed therein. The first mold comprises: a first mold body having an inner volume corresponding to an alumina plate; and an entrance formed on one side of the first mold body to input granular alumina powder. The second mold has a plurality of perforated plates assembled to be able to be separated from one another. Moreover, the second mold has the perforated plates, which have the plurality of through-holes formed therein, and assembled to one another in a shape of a hexahedron to envelop the first mold. Accordingly, a pressure medium is able to be introduced through each of the perforated plates of the second mold during a cold isostatic pressing process as the first mold is inserted through an entrance of the second mold; and afterwards, the entrance of the second mold is closed by the perforated plates after the entrance of the first mold is sealed. |
