摘　　要：运用Moldflow软件对汽车仪表板模具浇注系统及冷却系统进行验证及优化。结果表明:原经验设计6点进浇方案填充不均匀、模腔压力大、锁模力较高、模温不均匀、翘曲变形量较高;增加2个进浇口后填充较为均匀,锁模力降低15%,翘曲变形量降低22%,表面质量缺陷风险降低;增加1条水路后,凸、凹模模温相差在10.00℃以内,模温较均匀,冷却系统优化成功。浇注系统及冷却系统的优化使得大型模具的研发与制造成本降低,缩短了产品成型周期。The gating system and cooling system of the automotive dashboard mold were verified and optimized by Moldflow.The simulation results show that the original experience designed 6-point gating scheme has uneven filling,high mold cavity pressure,high locking force,uneven mold temperature,and high warpage deformation.After adding 2 gates,the filling is more uniform,the locking force is reduced by 15%,and the warpage deformation is reduced by 22%,so the risk of surface quality defects is reduced.After adding one waterway,the temperature difference between the punch and die is within 10.00℃,and the mold temperature is relatively uniform,indicating successful optimization for cooling system.The optimization for the gating system and cooling system saves developmeant and production costs of large molds and shortens product molding cycle.
