Structural design of plastic mold for automotive seat headrest
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 com-bined 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 ac-tual production demonstrated that this design scheme effectively shortened the product development cycle and improved the efficiency and quality of mold manufacturing.
