Abstract

Abdichtungselement zur Abdichtung des Überganges eines Polymerschmelze führenden Schmelzekanals 17 eines fest montierten Bauteils 11 in einen Schmelzekanal 18 eines demontierbaren, auswechselbaren Bauteils 12, wobei das Abdichtungselement aus einem zylindrischen und außen glatten Hohlkörper 15 mit einer axialen Bohrung 16 für den Schmelzedurchtritt besteht, welcher in den auswechselbaren Bauteil 12 in eine passende Aufnahmebohrung 19 eingesetzt wird und aus einem Werkstoff hergestellt ist, der einen höheren Wärmeausdehnungskoeffizienten hat als das ihn umgebende Material des auswechselbaren Bauteils 12.

Figure 00000001
Sealing element for sealing the transition of a melt channel 17 leading a polymer melt of a permanently mounted component 11 into a melt channel 18 of a removable, interchangeable component 12, the sealing element consisting of a cylindrical and externally smooth hollow body 15 with an axial bore 16 for the melt passage, which in the replaceable component 12 is inserted into a suitable receiving bore 19 and is made of a material that has a higher coefficient of thermal expansion than the material of the replaceable component 12 surrounding it.
