摘要
在汽车行业高速发展的今天,车灯的造型也更加复杂,车灯类塑件结构也随之多样化、复杂化发展,注射模结构也紧随着日渐复杂。作为模具结构中常用的弹块结构,更是成为了不可缺少的部分。普通的弹块难以适应双色塑件成型的要求,且存在着成型缺陷,难以满足塑件质量要求。设计了一种特殊的弹块结构,弹块顶部设计一凸台,弹块顶部凸台与动模型芯配合起定位、导向作用,防止弹块在合模过程中发生移动现象,同时弹块末端为零度面,起定位作用。实际使用结果表明:该结构完全适合使用在双色注射模中,且运行良好。
With the rapid development of automobile industry today,the modelling of auto lamps are becoming more and more complicated,besides,the diversified product mix and complicated develop of auto lamps lead to the complication of the stueture of injection mold which is the essential part as projectilebloek in mold structure.This article designed a special projectileblock structure to It is hard to resolve the forming defect and multi-color molding of the ordinary elastic and hard to fulfill the requirement of quality block.In order to prevent the movement of dynamic cavities of the progress of clampling,the top of the convex platform of projectilebloc and dynamic cavities will match up with each other to take effect to location and guiding.The bottom as the zero-surface to located too.In the end of the exprimental result indicated that it is completely suitbale for the mould of double color injection products and function well.
