Abstract: Based on the analysis of the structure characteristics and processing technology of the perfume bottle cap, an injection mould for this part was designed. The mould structure and its working process were introduced. The feeding system switching from pin-point gate to side gate，the demolding mechanism and the side core-pulling mechanism with lifter were illustrated in detail. The application instances of the feeding system switching from pin-point gate to side gate were introduced. It was proved that the feeding system switching from pin-point gate to side gate was adequate for setting of gate and filling of molded part.

Key words: perfume bottle cap, injection mould, feeding system, demolding mechanism, lifter, side core-pulling
