Abstract

The metal tube is sealed at one end whilst in the other end is a threaded stopper or cap containing two hose couplings and with a sheet metal strip between the coupling inlets and extending down the tube in a spiral almost to the opposite end.

Description

Kühl- oder Heizelement für Plastik-Formwerkzeuge Die Erfindung betrifft ein stabförmiges Kühl- oder Heizelement für Plastik-Formwerkzeuge, insbesondere zum Kühlen oder Beheizen solcher Zonen der Werkzeuge, die nicht in üblicher Weise mit Hohlräumen zum Durchströmen von Flüssigkeiten versehen werden können. Cooling or heating element for plastic molding tools The invention relates to a rod-shaped cooling or heating element for plastic molding tools, in particular for cooling or heating those zones of the tools that are not in the usual way can be provided with cavities for liquids to flow through.

Es ist bekannt, Plastik-Formwerkzeuge, insbesondere Spritzguß-, Rotationsguß- und Blasformen so auszubilden, daß ihre Wandungen Hohlräume enthalten, durch welche eine als Energieübertragungsmittel dienende Flüssigkeit strömt.It is known to use plastic molding tools, especially injection molding, rotational molding and blow molds so that their walls contain voids through which a liquid serving as an energy transfer medium flows.

Es ist jedoch meist schwierig, diese Hohlräume in den Formwandungen so zu gestalten, daß ein überall gleichmäßiger Flüssigkeitsstrom und somit ein überall gleichmäßiger Energieaustausch in der Form gewährleistet ist. Oft ist es daher erforderlich, mehrere Einzelkammern in der Formwandung vorzusehen, wobei jede Kammer auf eine bestimmte Zone der Forminnenwand wirkt. In Ecken und sehr engen Vertiefungen bestehen solche Kammern zuweilen nur noch aus einer Bohrung, die durch einen Schraubverschluß mit zwei Schlauchanschlüssen dicht verschlossen ist, wobei eine zwischen den Schlauchanschlüssen sitzende Zunge als Strömungslenker in die Bohrung hineinragt.However, it is usually difficult to create these cavities in the mold walls to be designed in such a way that a uniform flow of liquid everywhere and thus an everywhere uniform exchange of energy in the form is guaranteed. It is therefore often necessary to provide several individual chambers in the mold wall, each chamber on one specific zone of the inner wall of the mold. Exist in corners and very narrow recesses such Chambers sometimes only from a hole that goes through a Screw cap is tightly closed with two hose connections, one Tongue seated between the hose connections acts as a flow guide in the bore protrudes.

Es ist schwierig und erfordert sehr viel Zeit, in bestimmten Fällen eine größere Anzahl solcher Kühl- oder Iieizabschnitte an einem Formwerkzeug anzubringen.It is difficult and time consuming in certain cases to attach a larger number of such cooling or Iieizabschnitt on a mold.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Kühl- oder Heizelement für Plastik-Formwerkzeuge zu schaffen, welches mit geringstmöglichem Aufwand ermöglicht, die Temperatur in der Formwand in der gewünschten Weise zu regeln.The invention is therefore based on the object of a cooling or heating element for plastic molding tools, which enables with the least possible effort to regulate the temperature in the mold wall in the desired manner.

Die Lösung dieser Aufgabe ist ein stabförmiges Kühl- oder Heizelement, welches aus einer an einem Ende geschlossenen Röhre besteht, deren anderes Ende mit einer zwei Schlauchanschlüsse enthaltenden Kappe oder Stopfen verschlossen ist, wobei zwischen den beiden Öffnungen der Schlauchanschlüsse eine Blechzunge angesetzt ist, die in das Innere der Metallröhre bis nahe an deren anderes Ende hineinragt.The solution to this problem is a rod-shaped cooling or heating element, which consists of a tube closed at one end, the other end is closed with a cap or stopper containing two hose connections, a sheet metal tongue attached between the two openings of the hose connections which protrudes into the interior of the metal tube to near the other end thereof.

Zweckmäßigerweise ist diese Metallzunge schraubenförmig gedreht.This metal tongue is expediently turned helically.

Die Erfindung ist anhand einer sie beispielsweise wiedergebenden Zeichnung näher erläutert. Der Gegenstand ist in einem Längsschnitt dargestellt.The invention is based on a drawing showing it as an example explained in more detail. The object is shown in a longitudinal section.

Das erfindungsgemäße Kühl- oder Heizelement besteht aus einer an einem Ende geschlossenen Metallröhre 1, deren anderes Ende mit einem Schraubstopfen 2 verschlossen ist, welcher zwei Schlauchanschlüsse 3, 4 aufweist. Zwischen den Öffnungen der Schlauchanschlüsse 3, 4 ist eine Blechzunge 5 angesetzt, die in das Innere der Metallröhre 1 bis dicht an deren geschlossenes Ende la hüieinragt. 13ei diesem Beispiel ist die Blechzunge 5 5 c hi'aubenförmig gedreht. Sie kann jedoch gegebenenfalls auch gerade sein. Durch die schraubenförmige Drehung findet jedoch ein gleichm äßi geier Energieaustausch statt.The cooling or heating element according to the invention consists of one on one End of closed metal tube 1, the other end of which with a screw plug 2 is closed, which has two hose connections 3, 4. Between the openings the Hose connections 3, 4 a sheet metal tongue 5 is attached, the protrudes into the interior of the metal tube 1 to close to its closed end la. In this example, the sheet metal tongue 5 5 c is rotated in the shape of a dome. However, it can possibly also be straight. However, due to the helical rotation an even exchange of energy takes place.

Das Element sitzt in einer Bohrung der Formwand 6, wo es durch eine kleine Schraube 7 festgehalten wird. Die Befestigung kann auch in der Weise erfolgen, daß der Schraubstopfen 2 ein über den Umfang der Metallröhre 1 vorstehendes Außengewinde besitzt, mit dem er in der zu diesem Zweck mit Innengewinde versehenen Bohrung in der Formwand befestigt ist, Es ist auch eine Befestigung mit anderen an sich bekannten Mitteln möglich.The element sits in a bore of the mold wall 6, where it is through a small screw 7 is held. The attachment can also be done in such a way, that the screw plug 2 has an external thread projecting over the circumference of the metal tube 1 possesses, with which he in the for this purpose provided with internal thread bore in the mold wall is attached, There is also an attachment with other known per se Funds possible.

Die als Energieträger dienende Flüssigkeit strömt durch den einen SchlauchanschLuß 3 in die Metallröhre hinein, an der Blechzunge 5 entlang bis an deren Ende und auf der anderen Seite wieder zurück.The liquid that serves as an energy carrier flows through one Hose connection 3 into the metal tube, along the sheet metal tongue 5 to their end and back on the other side.

Ein besonderer Vorteil des erfindungsgemäßen Kühl- oder Heizelementes besteht darin, daß man es bei einem Formenwechsel ohne störenden Zeitaufwand im Ganzen bei angeschlossenen Schläuchen aus der einen Form herausnehmen und in die andere Form hineinsetzen kann. Dadurch werden die Rüstzeiten ganz erheblich verkürzt. Ein weiterer Vorteil besteht darin, daß man nur eine Schlauchanschluß-Garnitur für beliebig viele Austauschformen benötigt.A particular advantage of the cooling or heating element according to the invention consists in the fact that you can do it in the case of a change of shape without the need for a disruptive expenditure of time With the hoses connected, take the whole thing out of one mold and put it in the can put in another shape. This significantly shortens set-up times. Another advantage is that you only have one hose connection set for any number of exchange forms required.
