How to make core and cavity of complex modles?

I want to make Core and Cavity of a complex model.
I had made many core/Cavities of simple models. but none of complex.
I had attached a solid-works file of a spoon(having many complex surfaces) whose core-cavity is required.
The main problem occurs when i tried to make the parting line. !
I had also Tried making parting line using split line(sihouette type). but of no use.!
