Abstract
Description
Die Erfindung betrifft eine elektrisch beheizte Druckgussdüse für eine Warmkammer-Druckgießmaschine.The The invention relates to an electrically heated die casting nozzle for a hot chamber die casting machine.
Druckgussdüsen bzw. Mundstückkörper an Gießbehältern von Warmkammer-Druckgießmaschinen werden allgemein mittels elektrischer Widerstandsheizung auf eine zum Erhalt der notwendigen Viskosität des auszutragenden Gutes, wie flüssigem Magnesium, Zink oder ähnlichem, erforderlichen Temperatur gehalten.Die casting nozzles or Mouthpiece body on casting containers of Hot chamber die casting machines be generally by means of electrical resistance heating on a to obtain the necessary viscosity of the material to be discharged, like liquid magnesium, Zinc or similar, required temperature maintained.
Zur Regelung der Temperatur derartiger Druckgussdüsen ist es bekannt, Thermoelemente als Messwertgeber einzusetzen.to Control of the temperature of such die-cast nozzles is known, thermocouples to be used as a transmitter.
Mit
der
Nachteil dieser Anordnung des Thermoelements ist es, dass es im Verlauf des Düsenkörperkerns zu ungleichmäßiger Erwärmung, verbunden mit einer unzulässigen Abkühlung desselben kommen kann.disadvantage This arrangement of the thermocouple is that in the course of Nozzle body core to uneven heating, associated with an inadmissible Cooling of the same can come.
Die
Beseitigung dieses Nachteils wurde bereits mit einer mit der
Gemeinsamer Nachteil der genannten Lösungen zur Regelung der elektrischen Heizung einer Druckgussdüse bleibt es jedoch, dass beim Aufheizen des Mundstückkörpers bis zum Erreichen des Sollwerts der Düsentemperatur, eine massive, unnötig Energie erfordernde Überhitzung des elektrischen Heizelements sowie der umliegenden Bereiche des Düsenkerns, bis hin zur Zerstörung des elektrischen Heizelements eintreten kann.common Disadvantage of the solutions mentioned to control the electrical heating of a die-casting nozzle remains However, when heating the mouthpiece body until it reaches the set point the nozzle temperature, a massive, unnecessary Energy requiring overheating the electrical heating element and the surrounding areas of the nozzle core, to the point of destruction of the electric heating element can occur.
Wird diesem Nachteil mit einer Begrenzung der Leistung des elektrischen Heizelements begegnet, kann in der zur Verfügung stehenden Aufheizzeit die erforderliche Solltemperatur des Mundstückkörpers mit der Folge von Qualitätseinbußen der Druckgießteile gegebenenfalls nicht erreicht werden.Becomes this disadvantage with a limitation of the power of the electric Heated element encountered in the available heating time the required target temperature of the mouthpiece body with the result of quality losses of Die-cast parts may not be achieved.
Die Lösung dieser Aufgabe gelingt mit der Energiespardüse gemäß des Anspruches.The solution This object is achieved with the energy saving nozzle according to the claim.
Erfindungsgemäß ist dazu ein hier als Energiespardüse bezeichneter Mundstückkörper, bestehend aus einem Stahlkörper als Mundstückkörperkern mit in Längsrichtung verlaufenden, zur Vermeidung einer Schererewärmung strömungsgünstig ausgelegten Fließkanal, einem in spiralförig verlaufenden Quernuten in der Oberfläche des Stahlkörpers eingepressten elektrischen Heizelements, vorzugsweise einem eine Heizwendel enthaltenen elektrischen Rohrheizkörpers, einem über dem Mundstückkörperkern zur Fixierung und Isolierung des Heizelements aufgezogenen Stahlrohr, einem direkt mit dem Mundstückkörperkern in Berührung stehenden Thermoelements sowie eines weiteren, innerhalb der Heizwendel des elektrischen Rohrheizkörpers direkt mit diesem in Berührung stehenden Thermoelements.According to the invention is this one here as an energy saving nozzle designated mouthpiece body consisting from a steel body as the mouthpiece body core with in the longitudinal direction running, designed to avoid shear heating flow-oriented flow channel, one in a spiral extending transverse grooves pressed in the surface of the steel body electric heating element, preferably a heating coil contained electric tubular heater, one over the mouthpiece body core steel pipe mounted for fixing and insulating the heating element, one directly with the mouthpiece body core in touch standing thermocouple and another, within the heating coil of the electric tubular heater directly in contact with this standing thermocouple.
Ein mit diesen beiden Thermoelementen elektrisch verbundener Regler begrenzt die höchstzulässige Betriebstemperatur des elektrischen Heizelements im Zusammenwirken mit der Regelung der Betriebstemperatur des Mundstückkörperkerns durch pulsierendes Zu- bzw. Abschalten des elektrischen Heizelements unter Berücksichtigung der Temperatur des Rohrheizkörpers.One with these two thermocouples electrically connected controller limits the maximum operating temperature of the electric heating element in cooperation with the control the operating temperature of the mouthpiece body core by pulsating Switching on or off of the electric heating element under consideration the temperature of the tubular heater.
