耳机壳体塑件热流道注塑模的设计

摘要

The structure of the earphone shell plastic pattern is complex, and in order to solve the problem of long period of mold machine work, this paper analyzed the structure of the plastic parts for the earphone shell, designed and determined the selection of technological parameters, the master pattern and core pattern's structures based on the heat-transmitting system. Therefore, the molding process is warranted. Meanwhile, by employing a standard pattern and heat-transmitting system, the machining cycle time is shortened, the usage of material is saved and the working efficiency is improved, thus can meet the requirements of mass production.
