Abstract

Core connecting rod comprises a holding spring (3) made from tool steel connected to a rod (1) via a plate (2).

Description

BeschreibungCore connecting rod with retaining spring
Description

Gießformen bestehen in der Regel aus mehreren Form- und Kernteilen. Diese aus Formsand und Bindemittel vorgefertigten teile werden durch Kleber, Sonderschrauben und/oder Gewindestangen sog. Kernverbindungsstangen zusammengefügt. Grundsätzlich werden mittels Kernverbindungsstangen zwei oder mehrere Kerne zusammen gehalten.Casting molds usually consist of several mold and core parts. These parts, which are prefabricated from molding sand and binding agent, are joined together using adhesive, special screws and/or threaded rods, so-called core connecting rods. Basically, two or more cores are held together using core connecting rods.

Neu und erfindungsgemaß an dieser Kemverbindungsstange mit Haltefeder ist die Haltefeder, die sich beim Einschieben der Kemverbindungsstange in die dafür vorgesehene Aussparung (z.B. 40x40x25 mm tief) im Stirnkern in diesem aufgrundWhat is new and inventive about this core connecting rod with retaining spring is the retaining spring, which when the core connecting rod is pushed into the recess provided for it (e.g. 40x40x25 mm deep) in the front core in this

The rod is firmly clamped so that when screwing on the other end, it does not slip out of the recess and therefore does not require any manual counter pressure.
