用于注模装置的导套
摘要：
本发明涉及一种用于注模装置的导套。其中该导套(16)用于引导并密封注模装置的针阀喷嘴的闭合针，具有主体部(50)和紧固件(52)，该主体部(50)具有用于该闭合针的通孔(18)，该通孔(18)包括以微小的活动间隙包围该闭合针的至少一个导向部(20,22,24,26,28,30)，其中该通孔(18)包括至少两个扩张部(34,36,38,40,42)，所述扩张部的直径均大于所述至少一个导向部(20,22,24,26,28,30)的直径，本发明规定，导套(16)还包括能被紧固至该主体部(50)的紧固件(52)，其中密封件(80)布置在该紧固件(52)和该主体部(50)之间，抵靠在被插入该通孔(18)中的整个闭合针的外周面上。
摘要（英）：

Disclosed is a guide bushing for the guiding and sealing of a closing needle of a needle valve nozzle of an injection moulding apparatus, the guide bushing having a main part and a fastening element, wherein the main part has a through-opening for the closing needle, wherein the through-opening comprises at least one guiding portion, which encloses the closing needle with slight movement play, wherein the through-opening comprises at least two expansion portions, whose diameter in each case is larger than that of the at least one guiding portion. The guide bushing moreover comprises a fastening element, which is securable to the main part, wherein a seal element is arranged between the fastening element and the main part, bearing against the entire circumference of a closing needle inserted into the through-opening.
