Zusammenfassung: | The utility model relates to a powder metallurgy stagger displacement shaping mold which is shaped by dry powder of powder sintered steel parts and ceramic sintered part green bodies. The mold comprises an upper trimming die, a lower trimming die and a movable concave die which is arranged on the lower trimming die, wherein the lower trimming die is connected with a movable core which divides the concave die into two chambers, and at least one of the two chambers is in the same shape as a shaping blank; a guide groove is formed in the concave die, and the movable core is connected with the guide groove in a movable mode; a core driven-into rod which is opposite to the movable core is arranged in the upper trimming die, and the movable core and the core driven-into rod are both driven by a power mechanism. The utility model has the benefits that the powder metallurgy shaping mold provides a stagger displacement cavity shaping technical scheme aiming at arc-shaped shaping bodies, a powder containing cavity is d |
