A mold bed having a number of longitudinal mold cavities is surrounded by a reinforcement structure which permits the mold bed to be handled as a unitary product. Mold cavities have removable end walls, one at each of opposite ends, to promote releaseability of the product from the mold cavities once they are removed. The mold cavity has a trunnion, one at each of opposite ends of the mold body so that the mold body can be rotated from an upright position when it receives the concrete in the mold cavity to an upside down position whereby the products are removed of their own weight. Two transverse spaced channel straps extend across the open face of the cavity so that when the mold bed is turned upside down, the molded parts are held temporarily by the mold straps, which are then released by unbolting their connections with the mold bed. A fork-lift truck removes the molded parts ater the mold straps are removed. Cores are formed by inserts which extend through openings in the channel straps and are aligned with openings in the bottom of the cavities which promote release of the cores. A removable positioning means locates reinforcement rods at a proper location within the cavity during a pour. After the pour, the positioning means are then removed and the rod remains in place.
An apparatus for producing a number of molded concrete products from a single molding apparatus, comprising a mold bed having a mold means forming a plurality of elongated mold cavities and elongated mold walls and having reinforcement means surrounding said mold means and forming therewith a unitary structure whereby said mold bed can be carried as a whole, removable end wall portions of said mold cavity which are interfittable between the ends of the mold walls and the adjacent reinforcing means and are removable from said position, bracket means overlying the upper surfaces of said mold cavities and extending traversely to said elongated mold cavities at spaced-apart locations thereof, means for releaseably clamping said transverse bracket members to said reinforcement means, insert means associated with said transverse bracket members and adapted to extend within respective ones of said mold cavities to intersect with an opening at the bottom of a respective one of said mold cavities, load-bearing means receiving complementary portions of said mold bed and adapted for rotational inverting of said mold bed by rotation about said load-bearing means after the molded products are sufficiently hardened, and thereby transferring the weight thereof to the transverse bracket means, said removable clamping means securing said transverse bracket means, and providing detachment of said transverse bracket means to allow for gravity separation of the finished products from within the respective mold cavities.
