Abstract:
A mold and a process for non-manually cleaning the undercut along the bottom edge of the division plate which with a pallet under the mold defines a lip-forming subcavity results in a dry cast concrete block with an inside lip radius that is controlled to be within certain tolerances. Non-manually cleaning the undercut during the molding process can include spraying a jet of fluid, such as compressed air, at the undercut.
