摘要
分析了DVD门塑件的的结构特点和成型工艺,利用Moldflow/MPI软件的模流分析功能,确立了模具的浇注系统,采用了斜导柱抽芯机构,在抽芯滑块中巧妙地设计了一种防粘模机构,避免了侧抽芯时塑件粘留于模具的侧型芯上,实现了塑件的顺利脱模。最后阐述了模具结构与工作过程。该模具已投入批量生产,成型的塑件完全满足用户的质量要求。
The structural feature and forming technology of the DVD door panel were analyzed.By using Moldflow/MPI software,the feed system of the mould was ascertained.The angle pin core-pulling mechanism was adopted and the mechanism set inside the core-pulling slide preventing the plastic parts from adhering to the side core of the mould was designed,so the smooth demoulding of the plastic parts was realized.The structure of the injection mould and working process were discussed.The mould was already in mass production and the plastic parts could meet the customers' technical requirements.
