Minutes is a stretch. It will likely take multiple tools and setups to make a mold, and even more if you're starting from a billet that needs facing etc.
You could make this from reasonably sized stock with 2 setups. First you rough the shape and cut the mold cavity, then you remove the stock and face the backside. I'm used to an automatic tool changer, which would be needed if you want to go fast
