摘　　要：通过对音响面板的工艺性分析,借助CAD/CAE软件设计了一套一模两腔的四面侧抽芯热流道注射模具。详细分析并设计了该模具分型面与型腔布局、热流道浇注系统、抽芯机构和脱模机构等关键结构,阐述了该模具的工作过程。该模具采用了冷热流道结合的热流道浇注系统,通过2个潜伏式浇口从面板底部进料,保证了塑件外观质量,并使塑件脱模时凝料自动切除。实践证明,该模具设计合理,运行平稳,不仅提高了成型面板的质量,而且节省了材料,缩短了成型周期,可为面板类热流道模具的设计提供借鉴。Through the technical analysis of the audio panel,a set of four sides core pulling hot runner injection mold with one mould and two cavities was designed with the help of CAD/CAE software.The key structures of the mold were analyzed and designed in detail,such as the mold joint face and cavity layout,the hot runner casting system,the core pulling mechanism and the demoulding mechanism,and the working process of the mold was expounded.The mold adopted the hot runner casting system with cold and hot runner.Two latent gates were used to feed the plastic parts from the bottom of the plastic parts to ensure the appearance quality of the plastic parts,and the condensing material was automatically removed when the plastic parts were demoulded.It is proved by practice that the mold is designed reasonably and runs smoothly.It not only improves the quality of the forming panel,but also saves the material and shortens the molding cycle.It can be used for reference for the design of the panel hot runner mold.
