Description
Die Erfindung betrifft Führungs- oder Zulegestifte, welche zum Zusammensetzen vor! Formkästen benutzt werden. Unter den bisher bekanntgewordenen Führungsstiften sind auch solche mit einem Schlitz als besonders vorteilhaft im Gebrauch.The invention relates to guide or feed pins, which for assembly before! Molding boxes are used. Among the previously known guide pens those with a slot are also particularly advantageous in use.
Diese verlieren jedoch nach kurzer Zeit durch den laufenden Gebrauch ihr vorgeschriebenes Maß, so daß dann eine gute und einwandfreie Führung der Formkästen nicht mehr möglich ist.However, these lose after a short time due to ongoing use their prescribed level, so that then a good and proper management of the molding boxes is no longer possible.
Gemäß der Erfindung wird dieser Nachteil dadurch vermieden, daß im Innern der geschlitzten Führungsstifte zwei Federn angeordnet sind, welche ein Zusammenpressen der Stifte vermeiden. Auf diese Weise ist es möglich, daß sich die Stifte beim Zusammenlegen der Formkästen jeweils den vorhandenen Führunigslöchern anpassen können.According to the invention, this disadvantage is avoided in that in Inside the slotted guide pins two springs are arranged, which press together avoid the pens. In this way, it is possible that the pins when collapsing of the molding boxes can adapt to the existing guide holes.
In der Zeichnung ist ein Führungsstift gemäß der Erfindung dargestellt. Der Führungsstift r ist in bekannter Weise mit einem Schlitz 2 versehen. Die Federn 3 und 4 verhindern gemäß der Erfindung eine bleibende Verformung der Rohrwandung, durch die der Führungsstift durch unzulässiges Spiel in den Paßlöchern unbrauchbar werden würde, und bewirken, daß sich die Rohrwandung des Führungsstiftes stets an die Wand der Paßlöcher spielfrei anlegt.In the drawing, a guide pin according to the invention is shown. The guide pin r is provided with a slot 2 in a known manner. The feathers 3 and 4 prevent permanent deformation of the pipe wall according to the invention, which makes the guide pin unusable due to impermissible play in the fitting holes would, and have the effect that the pipe wall of the guide pin is always on the wall of the pass holes creates play-free.
