Have you tried Legos for the mold board and walls?

The rigid plastic of Legos lend themselves nicely to the mold board and then the bricks snap into the mold board - no need for glue or clay to seal the walls to the board - and they are reuseable.

I have never used Lego to build mold walls, but I've heard that folks love using them.

My only concern would be using them to cast a mold in plaster, as there is water involved and I'm not sure how perfectly sealed the seams between the bricks are.

But for all other applications, they sound like a great solution.
