Abstract: The process characteristics of automotive tailgate with carbon fiber composite were analyzed, and the structure design and the assembly process of its injection mould were introduced. The design points such as mould forming parts, parting level, gating system, carbon fiber inserts, side core-pulling mechanism, cooling system, vent system and demoulding system and the change function of mould type were analyzed. This mould structure was impact and its operation was stable, which met the precision and performance requirements of plastic parts.
Key words: automotive tailgate; carbon fiber composite material; injection mould; carbon fiber insert; side core-pulling mechanism
