Abstract

The grater board with punched holes is placed in the injection mould and the pressure applied as the moulding box is closed and embosses the holes as the plastic frame is moulded on.

Description

Verfahren zur Herstellung einer Küchenreibe Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Küchenreibe zum Zerkleinern von Lebenenittela, Gewürzen oder dgl., die aus einen von einen Kunststoffrahmen eilgefaßten Reibblech besteht. Dieses Reibblech weist eine Vielzahl von Ausgestanzten und goprägton Lochungen auf. Bisher wird ein Reibblech in der Weise hergestellt, daß das Blech zunächst mit den Lochungen ausgestanst wird. Hierauf folgt das Ausprägen der Lochungen. Erst dann wird das ausgestanzte und geprägte Blech in die Spritzgußfori gelegt und eingespant un den Kunststoffrahmen zu fertigen. Es sind also drei Arbeitsvorgange notwendig. Hinzu kommt der Nachteil, daß durch das Prägen der Lochungen Verziehungen und Verkürzungen des Blechs, insbesondere in Breitenrichtung entstehen. Method of making a kitchen grater The invention relates to on a method for making a kitchen grater for chopping food, Spices or the like. Coming from a friction plate eilgefaßten by a plastic frame consists. This friction plate has a large number of punched and goprünton perforations on. So far, a friction plate is produced in such a way that the plate initially is punched out with the holes. This is followed by the punching of the perforations. First then the punched and embossed sheet metal is placed in the injection mold and machined to manufacture the plastic frame. So there are three work processes required. In addition, there is the disadvantage that the embossing of the perforations causes distortions and shortenings of the sheet, especially in the width direction.

Der Erfindung liegt die Aufgabe zugrunde, die aufgezeigten Nachteile und Schwierigkeiten bei den bisher bekannten Herstellungsverfahren auf einfachste Weise dadurch zu beseitigen, daß insbesondere zwei bisher notwendige Arbeitsvorgänge vereinigt werden, und zwar in der Weise, daß die beil plastichen Prägen der Lochungen entstehenden Verziehungen des Blechs vermieden werden. Ihr Wesen wird insbesondere darin gesehen, daß die ausgestanzten Lochungen in einer Spritzguß-Ion während des Sohließvorganges der Gießform geprägt werden.The invention is based on the stated disadvantages and difficulties with the previously known manufacturing processes on easiest way to eliminate that in particular two previously necessary Work processes are combined in such a way that the beil plastichen Embossing of the perforations resulting distortions of the sheet are avoided. you Essence is seen in particular that the punched holes in a Injection molding ion are shaped during the sole casting process of the casting mold.

Eine Spritzgußform zur Ausführung des Verfahrens genuß der Erfindung ist insbesondere dadurch gekennzeiohnet, daß die Gußform Prägeplatten enthält, zwischen denen das ausgestanzte Reibblech durch den Schließdruck der Gußform prägend eingespannt ist.An injection mold for carrying out the method enjoy the invention is in particular gekennzeiohnet that the mold contains embossing plates between where the stamped friction plate is clamped in a formative manner by the closing pressure of the casting mold is.

Der Erfindungigegenstand ist auf der Zeichnung durch ein ius führungabeispiel schematisch dargestellt, und zwar neigt Abb. 1 einen Querschnitt durch eine Spritzgußf cra zur Ausfüh rung des Verfahren. gemäß der Erfindung ; Abb. 2 die Draufsicht auf einen Unterkasten mit eingelettem Reibblech.The subject of the invention is on the drawing by an ius management example shown schematically, namely Fig. 1 inclines a cross section through an Spritzgußf cra to carry out the procedure. according to the invention; Fig. 2 is a top view a lower box with embedded friction plate.

Es liegt ii Wesen der Erfindung, den zu Schließen der Gußform notwendigen Druck auszunutzen, um die Lochungen des eingelegten Reibblechs zu prägen. Hierbei wird der Vorteil erreicht, daß der sonst notwendige Prägevorgang zum Fortfall kommt und während des Sohließens der Spritzgußform durchgeführt wird.It is the essence of the invention, the necessary to close the mold Use pressure to emboss the perforations of the inserted friction plate. Here the advantage is achieved that the otherwise necessary embossing process is eliminated and is performed while the injection mold is being sole-poured.

Eine an sich bekannte Sprit4gußform zur Herstellung des Blechrahmens aus Kunetstoff besteht aus einem Oberkasten 1 uid einem Unterkasten 2. Gemäß der auf der ibbildung 1 dargestellten Aueführungsbeispiel befindet sich der rechte Teil des Oberkastens 1 in der Offenatellung und der linke Teil des Oberkastens 1 in der Schließstallung.A known injection mold for producing the Sheet metal frame made of plastic consists of an upper box 1 uid a lower box 2. According to the The right-hand part is located on the example shown in Figure 1 of the upper case 1 in the open position and the left part of the upper case 1 in the Closing stables.

Eine Spritzgußferm 1,2 zur Ausführung des Verfahrens gemäß der Erfindung enthält Prägeplatten. Die Prägeplatte 3 befindet sich in Oberkasten 1 und die Prägeplatte 4 in Unterkasten 2. Zwischen diesen Prägeplatten 3 und 4 ist das Beibblech 5 eingelegt. Bei gebffnetem Oberkanten 1 sind die Lechuegen 6 nicht geprägt und bei geschlossenem Oberkasten 1 eingedrückt, wodurch die Präguagen 7 entstehen. Der sum Schließen der Pormkasten 1 und 2 notwendige Druck wird ausgenutzt für des Prägen der Lochungea 6, wobel Verkürzungen des Blechs durch die Prägungen 7 vermieden werden, weil das Blech 5 auf seinen ganzen Oberflächen zwischen den Prägeplatten 3 und 4 fest eingespannt ist.An injection molding machine 1, 2 for carrying out the method according to the invention contains embossing plates. The embossing plate 3 is in the upper box 1 and the embossing plate 4 in lower box 2. The additional sheet 5 is inserted between these embossing plates 3 and 4. When the upper edge 1 is open, the Lechuegen 6 are not embossed and when the upper edge is closed Upper box 1 pressed in, whereby the stamps 7 are created. The sum closing the Porm box 1 and 2 necessary pressure is used for the embossing of the perforations 6, whereby the embossing 7 avoids shortening the sheet metal because the Sheet 5 firmly clamped on its entire surfaces between the embossing plates 3 and 4 is.

Es liegt weiterhin is Sinne der Erfindung, daß die Prägeplatton 3 und 4 in den Formkasten l und 2 austauschbar angeordnet sind. Hierdurch wird erreicht, daß in einer einzigen Spritzgußform 1,2 alle möglichen Ausgestaltungen der Lochmngen 6,7 geprägt werden können.It is also within the meaning of the invention that the embossing plate 3 and 4 in the molding box 1 and 2 are arranged interchangeably. This achieves that in a single injection mold 1.2 all possible configurations of the hole sizes 6.7 can be minted.

Es ist zweckmäßig, insbesondere in Unterkasten 2 Halstestifte 8 vorzusehen, die durch Lochungen 6 eines aus gestanzten und eingelegten Reibblechs 5 hindurchgreifen. Hierdurch wird erreicht, daß das Reibblech auch während des Prägevorgangs beim Schließen der Gußform 1,2 festgehalten ist.It is advisable to provide 2 neck pins 8 in the lower box in particular, punched out through holes 6 of one and inserted friction plate 5 reach through. This ensures that the friction plate also during the stamping process is held when closing the mold 1.2.
