The only reason they are called freeze plugs is if your engine freezes bad they will pop out and fall to the ground then you need new ones to go in a new block.

I believe manufacturers bore holes in your engine, place these leak makers to encourage you to trade for newer vehicles. I reject that they get sand out of a casting & I utterly reject that they relieve frozen blocks.
Only good thing ever made from a "freeze plug" is a hole to put a tea cup heater in.
No, it's not to get the sand out, but that is a secondary benefit.
The sand core that forms the water jacket has to be held in a precise position. It has extensions that are called core prints that are used to hold the core in the proper position. Those holes are where the core prints extend to the outer mold.
