摘　　要：通过分析塑料透镜组的结构工艺性和浇注系统方案,对塑件进行了优化设计。将热喷嘴置于塑件中心得到最优的充模过程。通过控制模温,改善其保压过程。采用定模推件板脱模,简化了模具结构。通过传统的注射成型工艺,生产出我司壁厚差异最大的LED透镜组。该模具设计可为同类型模具提供参考。By analyzing the structure of the plastic lens group and the gating system, the design of the plastic parts is optimized. The optimal filling process is obtained by placing the hot nozzle in the center of the plastic part. The holding process is improved by controlling the mold temperature. The mold structure is simplified by using stripper plate in the fixed half of mold for demoulding. Through the traditional injection molding process, we have produced the LED lens group with the largest difference in wall thickness. The design of the mold could provide reference for the same type of injection mold.
