HeißkanalisolierungHot runner insulation
15 Beschre ibung 15 Description
Die Erfindung betrifft eine Isolierung an einem Heißkanal für eine Kunststoff-Spritzvorrichtung oder dergleichen mit mindestens einem in einer Spritzdüse endenden Düsenkanal für einen plastifizierten Kunststoff, wobei der Heißkanal mittels einer Spanneinrichtung zwischen einer an der Kunststoff-Spritzvorrichtung befindlichen Aufspannplatte oder dergleichen und einer Formplatte eingespannt ist.The invention relates to insulation on a hot runner for a plastic injection device or the like with at least one nozzle channel for a plasticized plastic ending in a spray nozzle, wherein the hot runner is clamped by means of a clamping device between a clamping plate or the like located on the plastic injection device and a mold plate.
Heißkanäle dieser Art sind vorgesehen, um einen in ei-5 nem entsprechenden Vorratsbehälter auf Betriebstemperatur aufgeheizten Kunststoff zu einem Spritzwerkzeug transportieren zu können, wobei er noch spritzfähig sein muß, wenn er in eine an dem Spritzwerkzeug ausgebildete Form eintritt. Die Heißkanaldüsen und Heißkanäle sind zu diesem Zweck zumeist mit einer in der Regel elektrischen Heizung ausgestattet, welche den Heißkanal auf die erforderliche Temperatur aufheizt.Hot runners of this type are designed to transport plastic that has been heated to operating temperature in a corresponding storage container to an injection mold, whereby it must still be injectable when it enters a mold formed on the injection mold. For this purpose, the hot runner nozzles and hot runners are usually equipped with a heater, usually electrical, which heats the hot runner to the required temperature.
Es ist bereits bekannt, Wärmeverluste an derartigen Hei-ßkanälen zu vermindern, indem deren Gehäuse, die naturgemäß aus einem Metall hoher Wärmeleitfähigkeit bestehen müssen, mit schlecht wärmeleitenden Blechverkleidungen oder Isolierplatten abgedeckt werden. Eine solche Isolierung ist außerordentlich aufwendig und in ihrer isolierenden Wirkung begrenzt.It is already known that heat losses in such hot runners can be reduced by covering their housings, which naturally must be made of a metal with high thermal conductivity, with poorly heat-conducting sheet metal cladding or insulating panels. Such insulation is extremely complex and limited in its insulating effect.
Die Erfindung hat sich deshalb die Aufgabe gestellt, eine eingangs näher bezeichnete Isolierung so auszubilden, daß sie wirksam und mit geringem Aufwand an Montagezeit und Materialkosten herstellbar ist.The invention therefore has the task of designing an insulation as described in more detail above in such a way that it can be produced effectively and with little expenditure in terms of assembly time and material costs.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die von der Aufspannplatte und der Formplatte freibleibende Oberfläche des Heißkanals mit einem flexiblen, auswechselbaren, mattenförmigen Isoliergewebe verkleidet ist. Das Isoliergewebe kann aus mehreren Gewebe-Bahnen zusammenstückbar und mit geeigneten Schließen wie Knöpfen, Klettverschlüssen oder dergleichen versehen sein.According to the invention, the object is achieved in that the surface of the hot runner that is free from the clamping plate and the mold plate is covered with a flexible, replaceable, mat-shaped insulating fabric. The insulating fabric can be put together from several fabric strips and can be provided with suitable fasteners such as buttons, Velcro fasteners or the like.
Ein solches außerordentlich billiges Isoliergewebe ist leicht herstell- und an die jeweiligen baulichen Verhältnisse eines Heißkanals anpaßbar. Es verhindert Wärmeverluste durch Wärmeleitung, -konvektion und -strahlung gleichermaßen. Von der Isolierung ausgenommen bleiben gegebenenfalls, wenn vorhanden, die zumeist mit eigener Isolierung versehenen Heizungen zur Temperierung des Heißkanals.Such an extremely inexpensive insulating fabric is easy to manufacture and can be adapted to the respective structural conditions of a hot runner. It prevents heat loss through conduction, convection and radiation equally. The heaters for controlling the temperature of the hot runner, which are usually provided with their own insulation, are excluded from the insulation if present.
Der Heißkanal kann mittels Anschlagstücken spannbar sein, die an der Aufspannplatte und/oder der Formplatte anliegen, mit geeigneten Zentrierhilfen zum Zentrieren des Heißkanals versehen werden und aus einem schlecht wärmeleitenden Werkstoff wie Titan bestehen können. Auch die Anschlagstücke können von dem Isoliergewebe freibleiben.The hot runner can be clamped using stop pieces that rest on the clamping plate and/or the mold plate, can be provided with suitable centering aids for centering the hot runner and can be made of a poorly heat-conducting material such as titanium. The stop pieces can also remain free of the insulating fabric.
Die Erfindung wird nachstehend an Hand der Zeichnung an einem-Ausführungsbeispiel näher erläutert. Es zeigenThe invention is explained in more detail below with reference to an embodiment example and the drawing.

in schematischer, vereinfachter Darstellung.in a schematic, simplified representation.
Ein Heißkanal K ist zwischen einer Aufspannplatte P und einer Kunststoff-Spritzvorrichtung V eingespannt; in Schmelzkanälen D wird plastifizierter, erwärmter Kunststoff von einer Zuführung Z zu Spritzdüsen S gefördert. In der Zeichnung ist schematisch angegeben, wo sich Stromkabel E für die elektrischen Heizungen H und etwaige Temperaturfühler befinden; auch der sehr gut wärmeleitfähige Werkstoff für das Gehäuse des Heißkanals K ist vermerkt.A hot runner K is clamped between a clamping plate P and a plastic injection device V; in melt channels D, plasticized, heated plastic is conveyed from a feed Z to injection nozzles S. The drawing shows schematically where power cables E for the electric heaters H and any temperature sensors are located; the very good thermal conductivity material for the housing of the hot runner K is also noted.
Eine mattenförmiges Isoliergewebe I ist, das Gehäuse G bedeckend, so angeordnet, daß die Stromkabel E durchgeführt werden können. Auch die Heizungen H bleiben frei, genau so wie zur Einspannung und Orientierung dienende Anschlagstücke A, die aus einem schlecht wärmeleitenden Werkstoff bestehen können.A mat-shaped insulating fabric I is arranged to cover the housing G so that the power cables E can be fed through. The heaters H also remain free, as do the stop pieces A used for clamping and orientation, which can be made of a material that is poorly heat-conducting.
