摘　　要：针对双色牙刷柄头部材料单一、主体部分嵌有装饰性软材料的特点,确定采用转轴式双色注塑机成型,由此设计了一出八、十六腔的转轴式热流道双色注塑模,详细阐述了该转轴式双色注塑模的结构及工作原理。针对该模具的非自然平衡流道,利用 Moldflow 软件进行反复流动模拟分析和调整,最终确定了各型腔二级分流道的截面尺寸,实现了其流道系统的几何平衡,保证各型腔充填的平衡。最后还阐述了该双色注塑模热流道板的设计要点。A two-component injection mold with 16 cavities for it was designed for the molding of a twocolor toothbrush handle, in which the head part was made of a single material while the handle was decorated with a soft and colorful material. A two-component injection molding machine with rotary shaft was adopted. The structure and working process of the mold were introduced in detail. Moldflow was used to the design resulting in a balanced runner system. The design points of its hot-nmner plates were explained.
