For parts with large flat sides, you can just lightly glue them to a base plate. Then pour the mold. Pour spouts and vents aren't required in this circumstance because you can overpour the cavities, then just top the mold with a polypropylene sheet. Or you can use a hobby knife to cut pour spouts and vents into the mold after it is cured.
I later got rid of the spouts and vents and just did overfill casting because I could fill a mold, cover it with a propylene sheet, stack another mold on-top of it, fill that one, cap it with another sheet, and repeat until I had a whole stacked wedding cake of molds to transfer into the pressure pot.
