So? Do you get it?
(i.e. is infModel.getRawModel() an instance of NamedGraphModel?)

That's true.

I would expect you get the NamedGraphModel by calling getRawModel() - at least 
that's what the Jena Javadoc says.

The problem seems to be (I assume based on your use of the getGraph() method) 
that you are not interested in the NamedGraphModel that backs the infModel but 
you are interested in the NamedGraphSet that backs the NamedGraphModel. Right?
If so, you should be able to call 

( (NamedGraphModel) infModel.getRawModel() ).getNamedGraphSet()
