Sheet metal

Im trying to creat a sheet metal mold for a concrete slab, the slab has rounded edges along the outside. I want to make a 4 piece mold that connect at 45 degree angles. What is a good method to draw the curved edges of the mold so that i can use the sheet metal tool to get the flattened dimensions? As you can see the way i made the rounded edges from an extrude and then trim the extending parts (with an extrude set to remove till next) didn't result in a clean corner. The resulting sheet metal flat view also didn't come out how i wanted it too.

May it is possible to design a piece like this but it will not be possible to create a piece in this way. even in progressive stamping it would be difficult.
Think about a split somewhere
As @dirk_van_der_vaart said this might be hard to make but you can model it easily like this:

Here is another thought with hinged sides to release an flanged corners to hold corners,

If you want to create a concrete slab, maybe a silicon mold with a metal casing is an option. Pricepoint is very good, easy to replace.
I like the sound of that better than my own idea.
