Abstract

A line (5) supplies carbon dioxide under pressure into expansion regions (4) of the mold (1) prepared for it. Intentional expansion of carbon dioxide cools solid materials of the mold in these regions. Preferred features: Carbon dioxide is directed to mold regions with excessively-high temperatures. Its cooling effect is used there, to combat the following defects caused by excessive temperature: unwanted local reflectance or differences in reflectance in the molding, sink marks, defects due to mold release problems and/or damage to the mold material itself. The carbon dioxide is used in any region where generally-excessive temperatures arise.

Description

Bei der Herstellung von thermoplastischen Kunststoffartikeln werden Werkzeuge benötigt, die den in das Werkzeug geleiteten Kunststoff ausformen (z. B in einer Kavität) und anschließend abkühlen. Der oder die Artikel können bei Erreichen einer dem Kunststoff und der Geometrie zulässigen Temperatur aus dem Werkzeug entformt werden.Tools are required in the production of thermoplastic plastic articles, which mold the plastic that is fed into the tool (e.g. in a cavity) and then cool down. The one or more articles can reach the plastic and allowable geometry to be removed from the mold.

Dabei nehmen die Werkzeugtemperatur und die Temperaturverteilung entscheidenen Einfluß auf die Kühlzeit und die Qualität der produzierten Artikel.The tool temperature and the temperature distribution have a decisive influence on the cooling time and the quality of the articles produced.

Damit der Kunststoff abkühlen und eine bestimmte Werkzeugtemperatur beibehalten werden kann, muß die durch den Kunststoff in das Werkzeug eingebrachte Wärmemenge über ein Temperiersystem aus dem Werkzeug transportiert werden.So that the plastic cools down and a certain mold temperature is maintained can, the amount of heat introduced into the tool by the plastic must be about Temperature control system can be transported from the tool.

Werkzeuge für die Verarbeitung von thermoplastischen Kunststoffartikeln werden in der Regel mit Wasser oder Öl temperiert. Hierzu ist es notwendig, entsprechende Temperierungskanäle in das Werkzeug einzubringen, um das flüssige Medium durch das Werkzeug zu leiten. Um eine gleichmäßige Temperaturverteilung im Werkzeug zu erhalten ist es notwendig, bestimmte Abstände der Temperierkanäle untereinander und zur Kavitätsoberfläche einzuhalten, da ansonsten zu große Temperaturunterschiede im Werkzeug auftreten bzw. einzelne Bereiche im Werkzeug zu hohe Temperaturen aufweisen. Je weiter die Temperierungskanäle von dem qualitätsrelevanten Bereich entfernt sind, desto größer werden die Temperaturunterschiede zwischen Temperiermitteltemperatur und der qualitätsrelevanten Stelle im Werkzeug.Tools for the processing of thermoplastic plastic articles are used in the Usually tempered with water or oil. To do this, it is necessary to have appropriate Tempering channels in the tool to bring the liquid medium through the Tool. In order to obtain an even temperature distribution in the tool it is necessary to certain distances between the temperature control channels and each other The surface of the cavity must be adhered to, otherwise the temperature differences in the tool will be too large occur or individual areas in the tool have too high temperatures. The further the temperature control channels are from the quality-relevant area, the more the temperature differences between the temperature of the temperature control and the quality-relevant position in the tool.

Diese örtlichen Temperaturspitzen können zu erheblichen Kühlzeit- bzw. Zykluszeitverlängerungen im Prozeß oder zu qualitativen Nachteilen (z. B. Glanzstellen) an den Kunststoffartikeln führen.These local temperature peaks can lead to considerable cooling time or Cycle time extensions in the process or to qualitative disadvantages (e.g. shiny spots) the plastic items.

Besonders kritische Bereiche im Werkzeug sind also solche, in denen keine ausreichende Temperierung eingebracht wird (z. B. aufgrund von Platzproblemen oder fertigungstechnischen Problemen). Diese kritischen Bereiche können z. B. Kerne, Schieber, Heißkanaldüsen oder sonstige beweglichen und kleinvolumigen/dünnwandigen Werkzeugelemente sein, in denen oftmals nur mit sehr hohem technischen Aufwand eine gezielte Temperierung eingebracht werden kann.Particularly critical areas in the tool are those in which there are insufficient ones Tempering is introduced (e.g. due to space problems or manufacturing problems). These critical areas can e.g. B. cores, sliders, Hot runner nozzles or other movable and small-volume / thin-walled Be tool elements in which often only with a very high technical effort targeted temperature control can be introduced.

Neben der Temperierung von Werkzeugen, bzw. Werkzeugelementen mit Wasser oder Öl sind bereits Anwendungen einer Kühlung mit Kohlendioxid (CO2) in Kombination mit sinterporösen Metallen aus der WO 96/35563 A1, der WO 92/15439 A1 sowie der DE 33 22 312 C2 bekannt.In addition to the tempering of tools or tool elements with water or oil, cooling with carbon dioxide (CO 2 ) in combination with sinterporous metals from WO 96/35563 A1, WO 92/15439 A1 and DE 33 22 312 C2 are already used known.

Durch die Druckentlastung von Kohlendioxid damit verbundenen Änderung des Aggregatzustandes (Wechsel von einer flüssigen in eine gasförmige Phase) wird dem Bereich, in dem die Druckentlastung stattfindet, Wärme entzogen.The change in pressure associated with the release of carbon dioxide Physical state (change from a liquid to a gaseous phase) is the area in which the pressure relief takes place, heat is removed.

Das Kohlendioxid wird über einen Expansionsraum durch die Poren geleitet, die Temperaturabführung erfolgt über das Porensystem bis nahe unter die Werkzeugoberfläche. Das expandierte Gas wird anschließend über Evakuierungskanäle aus dem Werkzeug geleitet.The carbon dioxide is passed through an expansion space through the pores Temperature is dissipated via the pore system to almost below the tool surface. The expanded gas is then led out of the mold via evacuation channels.

Diese Anwendung der Temperierung erfolgt also nur bei gleichzeitiger Nutzung des Kohlendioxids mit dem mikroporösen Stahl. This application of temperature control is therefore only possible when using the Carbon dioxide with the microporous steel.  

Hier setzt die erfindungsgemäße Lösung an.This is where the solution according to the invention comes in.

Da diese mikroporösen Stähle nicht in jedem Werkzeug eingesetzt werden, bzw. wurden, sollen auch Bereiche im Werkzeug mit Kohlendioxid gekühlt werden, die nicht aus mikroporösen Stahl, sondern aus "konventionellen", nicht porösen Materialien gefertigt sind. Solche Materialien können massive Werkstoffe wie z. B. Stahl, Aluminium, Kupfer und sonstige Legierungen sein, die im Werkzeugbau Anwendung finden.Since these microporous steels are not or have not been used in every tool, Areas in the tool should also be cooled with carbon dioxide that are not microporous steel, but are made of "conventional", non-porous materials. Such materials can be massive materials such. B. steel, aluminum, copper and other alloys that are used in tool making.

In diese massiven Materialien werden Expansionsräume eingearbeitet (z. B. durch eine Bohrung), in denen das noch unter hohem Druck befindliche Kohlendioxid geleitet wird. Eine Zuleitung kann über kleine Röhrchen oder flexible Schläuche erfolgen. Beim Austritt aus diesen Zuleitungen findet eine Druckentlastung statt, dadurch wird der Umgebung in diesem Bereich sehr stark Wärme entzogen. Durch weiter nachströmendes Kohlendioxid wird das bereits expandierte Kohlendioxid über den Freiraum zwischen Zuleitung und der Wandung des Expansionsraumes (bzw. dem Bereich der Zuleitung) aus dem Werkzeug transportiert. Das nun gasförmige Kohlendioxid kann an die Umgebung abgegeben (bei geringen Konzentrationen) oder über ein spezielles System aufgefangen und anschließend wieder aufbereitet werden.Expansion spaces are incorporated into these solid materials (e.g. through a Hole) in which the carbon dioxide, which is still under high pressure, is conducted. A supply line can take place via small tubes or flexible hoses. When leaving These supply lines are depressurized, which means that the environment in them Area very strongly removed from heat. The carbon dioxide that flows in will Carbon dioxide has already expanded via the space between the supply line and the wall of the expansion space (or the area of the supply line) is transported out of the tool. The now gaseous carbon dioxide can be released into the environment (at low Concentrations) or collected via a special system and then again be processed.

Der Vorteil dieser Anwendung ist es, daß das Kohlendioxid über das Zuleitungssystem in jedes Werkzeugmaterial eingebracht und somit für eine Kühlung genutzt werden kann. Somit können auch bereits existierende Werkzeuge mit dieser Technologie nachgerüstet werden, bei denen Probleme mit zu hohen Temperaturen auftreten.The advantage of this application is that the carbon dioxide in through the supply system every tool material can be brought in and used for cooling. This means that existing tools can also be retrofitted with this technology with problems with excessive temperatures.

Für die Zuleitung, bzw. die Wärmetauscherfläche ("Expansionsraum") und die Abführung des Gases werden z. Zt. Aussparungen mit einem Durchmesser/Höhe von lediglich ca. 2 mm benötigt. Dadurch können nun auch erstmals Bereiche im Werkzeug gekühlt werden, in denen zuvor (aus technischen und wirtschaftlichen Gründen) keine gezielte Temperierung eingebracht werden konnte. Natürlich kann dieses Verfahren auch bei größeren Querschnitten zum Einsatz kommen.For the supply line or the heat exchanger surface ("expansion space") and the discharge of the Gases are e.g. Currently cutouts with a diameter / height of only approx. 2 mm needed. This means that areas in the tool can now be cooled for the first time no specific temperature control beforehand (for technical and economic reasons) could be introduced. Of course, this procedure can also be used for larger cross sections are used.

An zwei Beispielen soll das Verfahren verdeutlicht werden:The process will be illustrated using two examples:

Beispiel 1example 1

Kerne mit einem Außendurchmesser von ca. 7 mm und größer können nach dem Stand der Technik mit flüssigen Medien gekühlt werden. Hierzu muß in die Kerne eine Zu- und Ableitung für das flüssige Medium eingebracht werden. Bei Kernen mit kleineren Abmessungen wird es allerdings sehr schwierig und oftmals sehr kostenintensiv (Fertigungsaufwand, Temperiergeräte mit hohen Druck- und Temperierleistungen). Als zusätzliches Problem tritt in der Praxis häufig ein Verstopfen (z. B. durch Ablagerungen von Kalk) des Systems auf, wodurch die Wärmeabfuhr deutlich reduziert, bzw. vollständig unterbunden wird.Cores with an outer diameter of approx. 7 mm and larger can, according to the state of the Technology can be cooled with liquid media. To do this, a feed and Derivation for the liquid medium can be introduced. For cores with smaller ones However, dimensions make it very difficult and often very expensive (Manufacturing effort, temperature control units with high pressure and temperature control outputs). As In practice, an additional problem is often clogging (e.g. due to deposits of Lime) of the system, which significantly reduces the heat dissipation, or completely is prevented.

Bei Einsatz der Kohlendioxid-Temperierung, bei der nur geringe Zuleitungs- und Wärmetauscherquerschnitte benötigt werden, können nun auch Kerne oder sonstige Werkzeugelemente mit einem Außendurchmesser von nur ca. 3 mm oder entsprechender Wanddicke gezielt und dauerhaft temperiert werden, da durch das ausströmende Kohlendioxid keine "Verstopfungen" auftreten. When using carbon dioxide temperature control, with only a small supply and Heat exchanger cross sections are required, can now also cores or other Tool elements with an outer diameter of only approx. 3 mm or equivalent Wall thickness can be controlled in a targeted and permanent manner, because of the escaping carbon dioxide no "blockages" occur.  

Beispiel2Example2

In einem bestimmten Bereich von einem Werkzeug treten örtlich hohe Temperaturen auf, die unterbunden werden sollen. Aufgrund von fertigungstechnischen Gründen können aber vorhandene Temperierleitungen nicht nahe genug an diese Problemzone herangearbeitet werden (z. B. sitzen in diesem Bereich andere Funktionselemente wie Auswerfer etc., an denen kein dichtes Temperiersystem vorbeigeführt werden kann).In a certain area of a tool, locally high temperatures occur that should be prevented. Due to manufacturing reasons, however existing temperature control lines were not worked close enough to this problem area (e.g. other functional elements such as ejectors etc. are located in this area on which no tight temperature control system can be passed).

Durch die geringen Abmessungen des flexiblen Zuleitungssystems kann das Kohlendioxid über entsprechende Aussparungen mit etwas größeren Abmaßen als die Zuleitung gezielt in die kritischen Bereiche geleitet werden und dort aufgrund der Druckentlastung die Wärme abführen.Due to the small dimensions of the flexible supply system, the carbon dioxide can through appropriate recesses with slightly larger dimensions than the supply line specifically in the critical areas are directed and there the heat due to the pressure relief dissipate.
