I need some advice from anybody in the silicone mold business or knows somebody in that business. I need some simple molds made to order. Rather simple shapes. Basically molds in the shape of spheres but since the diameters would be 12 inches and larger I would need the spherical shapes to be divided. That way they could be layered like layer cake and then covered with icing and designs.
I've contacted several silicone mold companies that specialize in mold for baking but, surprisingly, they are unable to provide such molds. As I stated the shapes of the molds are obviously rather simple. I have seen spherical molds for baking but the dimensions are smaller. Sections are needed to provide for more even baking.
If anybody out there knows of such a silicone mold company that can make such baking molds, please FreepMail me. Thanx in advance.

That is EXACTLY what I am looking for. 4 different mold cuts. Three of them being the top HALF of the sphere and the final base section the part of the sphere approximately 40% below the diameter. For a 12" diameter sphere I estimated that the latter section would have a depth of 2.41". That latter section would also serve as the first section ABOVE the diameter at its widest (12") as well. The 3.49" remaining of the top section would be divided into two sections say 1.74" and 1.75". Those depths should allow for even baking probably without the need for a heating core. Then after baking assemble the 2 sections, cover with icing and design, and VOILA, a spherical cake.
Consider these:

There are a number of different sizes, so, with proper aluminum supports and weighting, a smaller diameter bowl could be nested inside a larger one and the space in between filled with batter.
Alternatively, you could use stainless steel or glass oven proof mixing bowels. Here is a YouTube video on this approach:

Read the comments as special precautions are needed to ensure the center of the half sphere bakes through. Of course, your cake diameter would be determined by the size of the bowl and here is a set of 12 12-inch stainless steel bowls that might work:

Good Luck!
I think you may have to try to make it yourself.
The type of silicone that is food safe is what they call platinum cure silicone rubber. The material of the object that will be used to make the mold can’t contain any sulfur or several other contaminants, or the silicone won’t cure.
There are several platinum cure silicones that are food grade safe.
See here for a couple of them. There are others by other companies. too.

I figured
So, make a wooden/plastic frame and use that to form the mold?
I don’t know a thing about silicone molds. I’m Old School. ;)
But you know a lot about baking, right?
Is that a dog dish? Of the inside of an opera soprano’s armor breastplate?
general info - I haven’t played with platinum cure silicone rubber, only the tin stuff, but I think this is correct.
platinum cure silicone rubber is sensitive to sulfur and other contaminants, and it won’t get hard (cure).
You can’t cure platinum cure silicone on a tin cure silicone mold or any object that has contaminants.
Therefore, if you have to create a mold of something big or porous, you should
take the object.
make a negative mold of the object with tin cure silicone rubber
make a positive copy of the object with resin (doesn’t have to be a solid piece of resin, can be hollow), and clean up the resin (smooth it, etc.)
clean the resin really well
then make a negative mold with the resin out of platinum cure silicone, which is then going to be used to bake the cake in.
For the platinum cure silicone mold, you will need to figure out how to support it when it is filled.
It is, apparently, a bust-shaped jello mold.
