Abstract

PURPOSE: To reduce unevenness in packing and to prevent the occurrence of cracks in a molded body during extraction by connecting 2 cylinders to a core rod section in series and moving the core rod in 3 steps.
CONSTITUTION: An upper cylinder 7 and a lower cylinder 9 are connected to the core side core rod 5 of a press molding machine for powder metallurgy in series through a coupling 8. By actuating the cylinders 7, 9, the rod 5 connected to the cylinder rods 6, 9 is moved in 3 steps.
