Abstract: A mold is provided for use in the production of concrete pipe sections. The mold has an inner mold part including an arch-shaped mold member; a pair of substantially L-shaped side mold members each flexibly connected to an adjacent end of the arch-shaped mold member and extending along the side portions of the mold and with parts extending inwardly across the bottom portion of the mold, and a separable mold member detachably connected between the inwardly extending parts of the L-shaped side mold members. The parting of the mold from the product is accomplished by removing the separable mold member, and urging the L-shaped side mold members inwardly. Provided also is a mold for use in the production of mitred concrete pipe sections comprising an upper inclined pipe and a lower inclined pipe which are connected to each other at their mitred surfaces. A mold is also provided for producing concrete pipe elbows having partition plates adapted to produce elbows of various arcuate sizes.
