摘　　要：以芯层发泡降噪管材挤出模为研究对象,优化设计芯层发泡降噪管材,以多层共挤挤出模为设计要点,通过模具流道均衡设计优化薄壁熔体流动性。设计的芯层发泡降噪管材挤出模具有结构合理、易于加工、成型高效、使用寿命长久的优点。The optimization design was made on foam-core denoise pipes by taking an extrusion tooling as study object; And the thin melt fluidity was optimized through the runner balance design, which point was multi-layer co-extrusion tooling.
