I have used graphite grease and one coating works well for multiple pours. It smokes a small amount when heated but the graphite remains on the mould even aftr several pours and continues to offer protection against wielding and any siezing. I got my grease from a diesel mechanic, but I'm thinking it should be available at any good auto parts store. Just brush it on the entire surface to be exposed to your pour and be sure to pre-heat your cast iron mold.
