You can't get a matte finish out of a shiny mould. Only way to sort of do it is to spray PVA release agent as a 'dust' to take the shine away. But it isn't a true matte, its more of a texture. 

You can get a good matt finish post demoulding with a satin/matt lacquer.  However as Hanaldo said, no way to really get it a matt finish straight from the mould.
