SchraubenfederCoil spring
Die Neuerung betrifft eine Schraubenfeder aus Kunststoff.The innovation concerns a coil spring made of plastic.
Sollen Schraubenfedern aus Kunststoff in einer Spritzform hergestellt werden, so macht sich die Steigung der Windungen negativ bemerkbar. Die entstehenden Hinterschneidüngen machen eine Spritzform mit einem Kern und mindestens drei Aussenformteilen notwendig.Shall coil springs made of plastic in an injection mold are produced, the slope of the turns is noticeable negatively. The resulting undercuts make an injection mold with a core and at least three outer mold parts necessary.
Die Neuerung hat die Aufgabe., diesen Nachteil zu vermeiden. Neuerungsgemäss wird dies dadurch erreicht, dass die Steigung auf einen Teil jeder Windung begrenzt ist. Eine vereinfachte Spritzform wird hierdurch ermöglicht.The task of the innovation is to avoid this disadvantage. According to the innovation, this is achieved in that the Slope is limited to a part of each turn. This enables a simplified injection mold.
Wenn man die Trennlinie der Spritzform um 90° versetzt zu dem Pereich der Steigungen anordnet, ist die Aussenform aus nur- zwei Formhälften herstellbar* Weiterhin vereinfachend wirkt, dass die Schraubenfeder einen rechteckigen Querschnitt aufweist.If you arrange the dividing line of the injection mold offset by 90 ° to the area of the slopes, the outer shape is off only two mold halves can be produced * Further simplifying acts that the coil spring has a rectangular cross section.
Weitere Vorteile sind aus der nachstehenden Beschreibung einps Ausführungsbeispieles, das die Neuerung nicht auf dieses einschränkt, und der Zeichnung ersichtlich. In der Zeichnung zeigt:Further advantages can be found in the following description of an exemplary embodiment that does not include the innovation this restricts, and can be seen in the drawing.

In der in Fig. 1 dargestellten Schraubenfeder 2 aus Kunststoff sind die Bereiche der Steigung mit 1 bezeichnet. Die Bereiche 1 der Steigung liegen genau gegenüber, um eine gleichmässige Verformung bei Belastung zu erreichen. Der übrige Teil der Windungen verläuft waagerecht und parallel zueinander und weist keine Steigung auf. Weiterhin ist der rechteckige Querschnitt der Schraubenfeder 2 zu erkennen.In the plastic helical spring 2 shown in FIG. 1, the areas of the slope are denoted by 1. the Areas 1 of the slope are exactly opposite in order to achieve an even deformation under load. the The remaining part of the turns runs horizontally and parallel to one another and has no slope. Furthermore, the rectangular cross-section of the helical spring 2 can be seen.
Aus Fig. 2 ist ersichtlich, dass die Bereiche 1 der Steigunger, sxch genau gegenüberliegen und der übrige Teil der W:ndungen parallel zueinander verläuft. Die Trennlinie der Spritzforr, liegt um 90 zu den Bereichen 1 der Steigung ver-Sc ,zt Λ·ά es ist daher möglicn, eine einfache Spritzfortn n.c nur zwei äusseren Formhälften herzustellen.From FIG. 2 it can be seen that the areas 1 of the inclines are exactly opposite one another and the remaining part of the turns runs parallel to one another. The dividing line of Spritzforr, is around 90 to the regions 1 of the slope ver-Sc, Λ · zt ά is therefore möglicn, a simple spray Fortn nc produce only two outer mold halves.
