Abstract: Aiming at the bumper of the CD539MCA car, the CAD technology was used to design the mould for bumper, and the CAE analysis technology was used to determine the number and location of gates. In the mould design process, the internal parting level technology, the hot runner sequence valve control system and the conformal cooling water circuit were applied to realize the goal of high requirements of the product appearance, and the three-level ejection technology was applied to achieve the demoulding of the bumper. Finally, the qualified products were obtained.
