摘　　要：介绍了一种用于某型号汽车座椅头枕的塑胶模具结构设计。通过成型工艺分析、脱模机制、模流分析等,提出了一种复合模具结构的设计方案,结合了哈夫行位、燕尾式大斜顶、斜内顶和直顶抽芯等组合,以解决产品迭代制造中的技术挑战。通过模流分析验证,本设计方案能够成功预防模具和产品的缺陷发生。经实际生产验证表明,该设计方案有效缩短了产品的开发周期,提高了模具制造的效率和质量。This paper reported a plastic mold structure design for a certain model of car seat headrest.A design scheme was proposed for a composite mold structure through analyzing the forming process,demolding mechanism,mold flow,etc.Meanwhile,the Haff position,dovetail large inclined top,inclined inner top,and straight top core pulling was combined to solve the technical challenges in product iterative manufacturing.Through the verification by flow analysis,this design scheme can successfully prevent against the defects occurring in molds and products.The verification results of actual production demonstrated that this design scheme effectively shortened the product development cycle and improved the efficiency and quality of mold manufacturing.
