Technologisches GebietTechnological area
Diese Erfindung erstreckt sich auf eine Form, vorrangig auf eine Form zur Herstellung von elektrischen Haushaltsgeräten, insbesondere von elektrischen Kühlschränken.This invention extends to a mold, primarily a mold for the manufacture of household electrical appliances, in particular electric refrigerators.
Technologischer HintergrundTechnological background
Elektrische Haushaltsgeräte, insbesondere elektrische Haushaltskühlschränke, verfügen in der Regel über einen wärmeisolierten Schrankkörper. Wie in Abb. 1 dargestellt, umfasst dieser Schrankkörper ein Außengehäuse 1. Dieses Außengehäuse 1 wird in der Regel aus metallischen Werkstoffen hergestellt, um die Festigkeit des Schrankkörpers zu erhöhen. Eine Seite des Außengehäuses 1 verfügt über zwei Öffnungen, die jeweils die Innenbehälter 2 aufnehmen. Die Innenbehälter 2 werden durch Formung aus einem Pressstoffmaterial hergestellt. Sie bilden die Aufnahmeräume 3 für die Aufnahme der darin abgelegten Lebensmittel usw. Zwischen den Innenbehältern 2 und dem Außengehäuse 1 befinden sich Zwischenräume. Diese Zwischenräume werden mit wärmeisolierendem Schäumungsmaterial ausgefüllt.Domestic electrical appliances, especially electric household refrigerators, usually have a heat-insulated cabinet body. As shown in Fig. 1, this cabinet body comprises an outer housing 1. This outer housing 1 is usually made of metallic materials in order to increase the strength of the cabinet body. One side of the outer housing 1 has two openings, each receiving the inner container 2. The inner container 2 are made by molding of a molding material. They form the receiving spaces 3 for receiving the food stored therein, etc. Between the inner containers 2 and the outer housing 1 are intermediate spaces. These spaces are filled with heat-insulating foam material.
Im Prozess der Herstellung des Schrankkörpers werden die Innenbehälter 2 zuerst in die Öffnungen des Außengehäuses 1 eingesetzt. Anschließend wird eine Form, deren Gestalt und Abmessungen mit dem Aufnahmeraum 3 der Innenbehälter übereinstimmt, in den Aufnahmeraum 3 eingesteckt. Dann wird das flüssige Schäumungsmittel über eine kleine Öffnung, die auf dem Außengehäuse angebracht ist, in die Zwischenräume zwischen Innenbehältern 2 und Außengehäuse 1 eingespritzt. Das flüssige Schäumungsmittel verfestigt sich in den Zwischenräumen schnell und füllt jede Ecke der Zwischenräume aus. Weil die Form eng auf der inneren Oberfläche 4 der Innenbehälter aufliegt, werden die Innenbehälter 2 im Prozess der Schäumung nicht durch den Druck des Schäumungsmaterials verformt. Nach dem Ende des Schäumungsvorgangs wird die Form aus den Aufnahmeräumen 3 entfernt.In the process of manufacturing the cabinet body, the inner containers 2 are first inserted into the openings of the outer case 1. Subsequently, a mold whose shape and dimensions coincide with the receiving space 3 of the inner container, inserted into the receiving space 3. Then the liquid foaming agent over a small Opening, which is mounted on the outer housing, injected into the spaces between inner containers 2 and outer housing 1. The liquid foaming agent quickly solidifies in the interstices and fills in every corner of the interstices. Because the mold rests tightly on the inner surface 4 of the inner containers, the inner containers 2 are not deformed by the pressure of the foaming material in the process of foaming. After the end of the foaming process, the mold is removed from the receiving spaces 3.
Da jedoch die Form im allgemeinen aus metallischem Aluminium hergestellt wird, kommt es im Verlauf einer langen Nutzung durch den Kontakt des Aluminiums der Außenflächen der Form mit dem Sauerstoff der Luft zu einer Oxydation und zur Bildung vonHowever, since the mold is generally made of metallic aluminum, over a long period of use by the contact of aluminum with the outer surfaces of the mold with the oxygen of the air, oxidation and formation of
Aluminiumoxyd. Das Aluminiumoxyd verteilt sich auf der Oberfläche der Form als Mikrokörnchen. Weil im Schäumungsprozess die Form und die Innenflächen 4 der Aufnahmeräume 3 engen Kontakt haben, reiben beim Herausnehmen der Form aus den Aufnahmeräumen 3 die Oberflächen der Form und die Innenflächen 4 der Aufnahmeräume 3 aneinander, was dazu führt, dass ein Teil der Körnchen ausAluminum oxide. The alumina disperses on the surface of the mold as microgranules. In the foaming process, since the mold and the inner surfaces 4 of the accommodating spaces 3 are in close contact, when the mold is taken out of the accommodating spaces 3, the surfaces of the mold and the inner surfaces 4 of the accommodating spaces 3 rub against each other, resulting in a part of the granules
Aluminiumoxyd auf den Innenflächen 4 der Aufnahmeräume 3 zurückbleibt, wie die Körnchen 5 in Abb. 1. Um die Sauberkeit des Schrankkörpers bei Übergabe an den Verbraucher zu gewährleisten, ist eine Entfernung dieser ungleichmäßig auf den Innenflächen 4 verteilten Körnchen 5 im manuellen Verfahren erforderlich, wodurch sich die Selbstkosten erhöhen.Aluminum oxide remains on the inner surfaces 4 of the receiving spaces 3, as the granules 5 in Fig. 1. In order to ensure the cleanliness of the cabinet body on delivery to the consumer, removal of these unevenly distributed on the inner surfaces 4 granules 5 in the manual process is required increase the cost price.

Konkrete Ausführungsweise Nachfolgend wird in Verbindung mit den Abbildungen die Form des vorliegenden Erfindung weitergehend detailliert beschrieben.Concrete execution Hereinafter, in conjunction with the drawings, the form of the present invention will be described in further detail.
Die Form einer konkreten Ausführungsweise dieses Gebrauchsmusters, wie in Abb. 2, wird aus metallischem Aluminium hergestellt. Sie umfasst eine Basis 6 sowie ein Hauptteil 7, das auf der Basis angebracht ist. Das Hauptteil 7 wiederum umfasst zwei durch einen Zwischenraum voneinander getrennte Teile. Die Gestalt und Abmessungen dieser beiden Teile entsprechen jeweils der Gestalt und den Abmessungen der Aufnahmeräume 3 der Innenbehälter des Schrankteils des entsprechenden elektrischen Haushaltskühlschranks. Die Oberfläche des Hauptteils 7 ist mit einer Oxydationsschutzschicht bestrichen, bei deren Hauptbestandteil es sich um Epoxidharz handelt. Das Epoxidharz härtet aus, bedeckt die Oberfläche des Hauptteils 7 und verhindert die Oxydation des metallischen Aluminiums durch den direkten Kontakt mit Luft. Die Dicke dieserThe shape of a concrete embodiment of this utility model, as in Fig. 2, is made of metallic aluminum. It comprises a base 6 and a main part 7 which is mounted on the base. The main part 7 in turn comprises two parts separated by a gap. The shape and dimensions of these two parts correspond respectively to the shape and dimensions of the receiving spaces 3 of the inner container of the cabinet part of the corresponding household electric refrigerator. The surface of the main part 7 is coated with an oxidation protective layer, the main component of which is epoxy resin. The epoxy hardens, covers the surface of the main part 7 and prevents the oxidation of the metallic aluminum by the direct contact with air. The thickness of this
Oxydationsschutzschicht aus Epoxidharz beträgt 30 Mikrometer bis 40 Mikrometer (30 um - 40 um). Eine solche Dicke kann sowohl die Abdeckung der Oberfläche des Hauptteils 7 gewährleisten als auch verhindern, dass die Schicht wegen zu großer Dicke mit den Innenbehältern aneinander reibt und dadurch abblättert.Oxidation protection layer of epoxy resin is 30 microns to 40 microns (30 microns - 40 microns). Such a thickness can both ensure the covering of the surface of the main part 7 and prevent the layer rubbing against each other due to excessive thickness with the inner containers and thereby peeling off.
Laut den statistischen Daten der Referenztabelle 1 waren, vor Aufbringen der Oxydationsschutzschicht auf der Formoberfläche, im Jahr 2006 von den Mängeln der Schrankkörper, die jeden Monat durch Flecken der Innenbehälter der Schrankkörper hervorgerufen wurden, ein maximaler Anteil von 63,77 % und selbst noch ein minimaler Anteil von 24,71 % der Mängel auf Flecken durch Reibung zurückzuführen, wobei der Grund für das Entstehen der Reibungsflecken eben genau in der gegenseitigen Reibung zwischen der Aluminiumoxydschicht der Formoberfläche und der Oberfläche der Innenbehälter bestand.According to the statistical data of Reference Table 1, before the application of the oxidation protection layer on the mold surface, in 2006, the defects of the cabinet bodies caused by stains of the inner containers of the cabinet bodies every month were a maximum of 63.77% and even one more At least a minimum of 24.71% of the defects were due to staining due to friction, with the cause of the frictional staining just being the mutual friction between the aluminum oxide layer of the mold surface and the surface of the inner containers.
Laut den statistischen Daten der Referenztabelle 2 war, nach Aufbringen der Oxydationsschutzschicht auf der Formoberfläche, in den ersten drei Monaten 2007 von den Mängeln der Schrankkörper, die durch Flecken der Innenbehälter der Schrankkörper hervorgerufen wurden, ein maximaler Anteil von 12,05 % der Mängel auf Flecken durch Reibung zurückzuführen, woraus ersichtlich ist, dass die Oxydationsschutzschicht das Entstehen von Reibungsflecken in großem Umfang verringert und die Ausschussrate der Innenbehälter gesenkt hat.According to the statistical data of Reference Table 2, in the first three months of 2007, after the application of the oxidation protection layer on the mold surface, of the defects, the cabinet body caused by stains of the inner container was the cabinet body 12,05% of the defects due to stains due to friction, it can be seen that the oxidation protective layer has greatly reduced the occurrence of friction marks and lowered the reject rate of the inner containers.
