【摘要】 针对汽车仪表板电镀饰圈的结构特点、外观及技术要求，设计了一种热流道转冷流道浇注系统。在热射嘴周围设计单独的冷却水道，解决因温度过高出现拉丝和浇口残留等问题。通过Moldflow对汽车仪表板电镀饰圈进行模流分析，针对两点进胶方式，找到最佳浇注位置。通过翘曲分析，得到翘曲变形量最大影响因素是收缩不均。利用正交实验法和极差分析得到最佳工艺参数，使翘曲变形量减少17%。更多还原

【Abstract】 According to the structural characteristics, appearance and technical requirements of the electroplated bezel of automobile instrument, a hot runner to cold runner gating system is designed. A separate cooling water channel is designed around the hot nozzle to solve the problems of wire drawing and gate residue due to excessive temperature. The mold flow analysis is carried out on the electroplating bezel of automobile instrument through Moldflow software, and the best pouring positions are found for the two-point glue feeding method. Through the warpage analysis, it is found that the largest influencing factor of the warpage deformation is the uneven shrinkage. Using orthogonal experiment method and range analysis to obtain the best process parameters, the amount of warpage deformation is reduced by 17%.更多还原
