Die for sintering and shaping porous material

The invention relates to the technical field of dies, in particular to a die for sintering and shaping a porous material. The die comprises a base. An upper die, a lower die and a pressing device forpushing the upper die downwards are arranged on the base; the pressing device presses the lower die downwards; materials are pressed and formed through the upper die and the lower die; the upper die comprises an upper die holder, an upper base plate and a falling mechanism which are sequentially arranged from top to bottom; the falling mechanism is used for pushing materials adhered to the upper base plate downwards; a pressure head mechanism for pressing materials is arranged on the upper base plate in the front-back direction, and is suitable for shaping a mold in the lower die; the lower die is provided with a magnetic positioning device which is suitable for positioning the material; the pressure head mechanism comprises a plurality of pressure head assemblies; the pressure head assemblies are connected with s
