轿车后视镜外罩注射模设计

Design of the Injection Mould for the Car's Rearview Mirror Cover

介绍了轿车后视镜外罩的成型工艺及注射模结构 ,为解决塑件的内侧抽芯和型芯的复位 ,模具采用了有双斜面的斜滑块结构 ,内抽型芯分解成7块、分次内抽芯。模具结构紧凑、内抽型芯可自动复位 ,提高了生产效率。

The technological process for forming the car's rearview mirror cover and the structure of the injection mould are introduced. The structure with a double-slanted slide and a core in 7 separated blocks which accomplish core-pulling in two times was used for the mould to realize automatic inner-core-pulling and reposition. The production efficiency has been increased.
