一种用于吹塑机生产线上开合模的紧固装置
本技术涉及塑料加工设备
,具体涉及一种用于吹塑机生产线上开合模的紧固装置。
技术介绍
吹塑也称中空吹塑,一种发展迅速的塑料加工方法。热塑性树脂经挤出或注射成型得到的管状塑料型坯,趁热或加热到软化状态,置于对开模中,闭模后立即在型坯内通入压缩空气,使塑料型坯吹胀而紧贴在模具内壁上,经冷却脱模,即得到各种中空制品。为了提高生产效率,吹塑机与传送带流水线结合,在吹塑机流水生产线上开合模在吹模、冷却完成后,下一个开合模替换上一个开合模进行重复吹模、冷却操作,达到提高生产效率的效果,而由于在工作时,生产线上的开合模自身稳定性差,机械震动容易造成开合模的抖动及不稳定性,从而使得产品的薄膜厚度不均匀或者薄膜有皱纹。
