Portable projector shell forming process and forming die and sawing machine used by portable projector shell forming process

The invention discloses a portable projector shell forming process and a forming die and a sawing machine used by the portable projector shell forming process. The portable projector shell forming process sequentially comprises the steps of designing a die-casting die, forming a blank through die-casting forming, sawing the blank to remove end surface cinder ladle materials and stub bars on the blank, and carrying out cutting machining and surface treatment on hole site cinder ladle materials on the bottom surface of the blank and axial two-end structures. The forming die comprises a male die and a female die, hole site cinder ladles are arranged on pairs of male sliding blocks and female sliding blocks which can slide into a male die cavity and a female die cavity in the direction perpendicular to the die assembly direction,end surface cinder ladles and exhaust structures which communicate with each other are arranged on the portions, at the two axial ends of a shell product, of the male die and the female d
