Abstract

Apparatus for molding blocks with laterally projecting, undercut side features includes a mold box having split mold parts defining a mold cavity open at the top and bottom. A top plate overlies the mold parts and is formed with an opening aligned with a cavity. Moldable block material is charged into the cavity from a feed box, and the material is compacted and shaped between a lower pallet and upper stripper head which are moved to close the bottom and top of the cavity during vibration of the mold. The mold parts are retractable beneath the top plate to release the block for stripping through the bottom of a mold. A plurality of fluid outlets in the top plate communicate with problem areas of the recessed mold parts which are prone to accumulate residual block material. Pressurized clean-out fluid, such as air is directed through the outlets onto such problem areas to cleanse the mold surfaces of the block material between mold cycles. An air knife is carried by the feed box and directs a high pressure curtain of air against the underside of the stripper head to remove any accumulated block material therefrom during movement of the feed box into and out of position over the mold.
