摘　　要：为满足某保健饮品瓶盖产品质量、外观形态、生产批量等工艺特性和生产需求,设计了1模16腔的叠层注塑模具。针对瓶盖的内表面非对称梯形螺纹、顶部凹点、防滑纹等结构特点,介绍了模具的浇注系统、冷却系统、顶出机构、分型面选择等结构,重点分析和计算了膨胀后的热流道喷嘴与型腔之间的间隙、冷却水道进、出口位置与温差控制的关系、脱模板与型芯的配作关系等,解决了瓶盖内表面脱模易拉伤、变形、精度不高等问题,保证了保健饮品瓶盖的成型质量,且实现了连续大批量生产。A laminated mould with 16 cavities was designed to meet the requirements of the product quality,appearance,production batch and other process characteristics of a health drink bottle cap.According to asymmetric trapezoidal thread of inner cap,top pits,antiskid stria and other structural features,the injection system,cooling system,ejector mechanism,parting surface selection of the mould was introduced.The gap between the swollen hot runner nozzle and the cavity,the relationship between the position of the inlet and outlet of the cooling water channel and the temperature difference control,the matched relationship between the stripping plate and the core and so on was analyzed to solve problems of the incidental strain in demoulding,deformation,low precision of inner surface and ensure the forming quality of the health drink cap and achieve continuous mass production.
