Compression molding device based on powder metallurgy

The invention discloses a compression molding device based on powder metallurgy, and relates to the technical field of powder metallurgy. The compression molding device based on powder metallurgy comprises an operation table, a lower die and an upper punch, the lower die and the upper punch are used for compression molding, the lower die is fixed to the upper end of the operation table, a lifting table is arranged above the operation table, and a die cavity is formed in the lifting table. According to the pressing forming device based on powder metallurgy, in the pressing forming process of powder, the operation box is matched with the moving assembly, the sliding assembly and the transmission assembly, powder forming machining is completed, in the forming machining process, the powder is sealed through the operation box, and an upper punch is arranged in the operation box; the powder is in a relatively sealed state in the filling and extruding processes, the probability that the powder which is not pressed a
