Zusammenfassung der ErfindungSummary of the invention
Hauptziel der Erfindung ist ein Umlenkeinsatz, der durch Vermeidung des durch den Materialfluss erzeugten Biegemoments auf den Ventilzapfen das Problem des starken Verschleißes löst.main goal The invention is a deflection insert, which by avoiding by the material flow generated bending moment on the valve pin the Problem of heavy wear solves.
Nebenziel der Erfindung ist ein Umlenkeinsatz, der auch das Auftreten der "toten Zone" vermeidet, da diese den Materialfluß stört und damit die Produktqualität vermindert.secondary objective The invention is a deflecting insert, which also avoids the occurrence of the "dead zone", as this disturbs the flow of material and thus the product quality reduced.
Ein Verteilerkanal führt das geschmolzene Kunststoffmaterial unter Druck zu, der in den Verteiler eingebaute Umlenkeinsatz ändert seine Fließrichtung um 90° und leitet es zum Düsenkanal weiter. Ein Ventilzapfen, der sich in Längsrichtung des Düsenkanals bewegt dient dazu, den Anguß zu öffnen und zu schließen, wodurch jeweils eine definierte Menge des geschmolzenen Materials durch den Anguß in die Form gelangt.One Distribution channel leads the molten plastic material under pressure, which is built into the manifold Reversing insert changes its flow direction around 90 ° and directs it to the nozzle channel further. A valve pin extending in the longitudinal direction of the nozzle channel moved serves to open the gate and close, whereby in each case a defined amount of the molten material through the sprue in the Form comes.
