Ingot moulds

Also found sometime to knock together Version 2.0 of the ingot moulds. This is will make eight moulds at a time. I have yet to test it to see if I can actually ram it up and release the sand but I don't expect any problems. I have used a draft angle on the moulds of 5 degrees, rather than the minimum 1 degree, so they should slip straight out.
Would quite like to get fancy and carve a logo into the moulds so I get branded ingots. God is in the details.
I'm pretty pleased with the progress I'm making on this project so far, it's not my usual ripshitandbust work.
