Title
(ZH) 用于挤出的环形模具和方法
Abstract
(ZH)
本发明涉及一种用于生产管状或片状预成型件的挤出头上的环形模具(1),所述环形模具具有弧形模具间隙并且具有由芯轴(2)和模具本体(3)界定的熔体通道(4),所述熔体通道(4)的横截面轮廓能够借助于调节元件而变化,根据本发明的环形模具的区别在于,所述熔体通道(4)的外圆周至少部分地由至少一个径向可调节的滑块(5)直接界定,所述滑块(5)由多个区段形成,这些区段能够一起进行调节,从至少一个第一位置调节到至少一个第二位置,并且这些区段在每个位置中形成所述熔体通道(4)的边界的相应闭合的弧形部分,所述弧形部分的半径根据这些区段的位置是不同的。
