Abstract: The car storage box has a complex structure, and there is no defect allowed on its appearance surface. For this reason, a flip injection mould was designed with a gate on the back of appearance surface. A hot runner system, a hydraulic cylinder ejecting mechanism, a four-sided hydraulic cylinder slide-pulling mechanism, and a two-step slide-pulling mechanism of lifter in large slide and little slide in larger slide on the fixed mould were designed. The results indicated that the structure of mould was reasonable and reliable and could meet the requirement for production.

Key words: flip injection mould, hot runner, fixed mould ejector, two-step slide-pulling mechanism
