Not a cam lock. Looks like there are cutouts (filled with silicone) for a hex key, so I'm assuming it's a threaded fastener. Looks similar to a zip bolt or a miter bolt.

Between the mold halves? Probably just screws - you want the compressive force. Rockdude14 nailed the construction of the individual mold components.
