Abstract

PURPOSE:To take out the parts having coaxial structure at an assembled state by following method in which the part with a shaft and the part with a shaft tube are simultaneously formed apart in the axial direction, and after molds are opened the shaft part is inserted into the shaft tube and is taken out. CONSTITUTION:A pair of side cores 5 spaced on both side are arranged between molds 3 and 4 of a pair which are attached to a stationary die plate 15 and a movable die plate 16 kept on a stationary fixing plate 17 and a receiving plate 18. A core pin 6 which is connected to the die 4 and whose small diameter part 21 is inserted into the die 3 is equipped between these cores 5. The cavity 31 of a first member 1 with a hollow part 11 between the mold 3, the core 5 and the pin 6, and the cavity 32 of a second member 2 with a shaft tube 13 through which the shaft 11 will be inserted, between the core 5, a large diameter part 22 and the mold 4. These two cavities 31, 32 are constructed. After synthetic resin is filled into the cavity 31 and 32 and the members 1 and 2 are simultaneously formed apart in the axial direction, the molds are released and the cores 5 are opened by an angular pin 24 and then an ejector pin 7 is protruded in the axial direction of a pin 6, thereby inserting the shaft 11 of the member 1 into the shaft tube 13 of the member 2.
