摘　　要：根据液压设备用塑件元件结构特点,进行成型工艺性分析,设计出一副斜导柱式侧向抽芯结构模具。该模具为一模四腔型腔分布,梯形截面分流道,圆形侧浇口进料的浇注系统,8根直径为4 mm圆形推杆推出机构,采用导柱导套导向方式。对整体模具结构工作过程进行分析,为相似结构塑件模具设计提供理论参考价值。Based on the structural characteristics of plastic components for hydraulic equipment,the article analyzes the forming process and designs a diagonal guide column type lateral core pulling structure mold.The distribution of four cavities of the the first mock examination,the trapezoidal section shunt channel,the round side gate feeding gating system,the eight circular push rod ejection mechanisms with a diameter of 4 mm,adopt the guide pillar guide sleeve guidance mode,and analyze the working process of the overall mold structure,providing theoretical reference value for the mold design of plastic parts with support structures.
