1. An apparatus for the production of concrete blocks, in which a lower mold part (8) is inserted into a frame (14) that is attached, by way of retaining braces (16), to holders (18) of multiple guidance columns (20), which are oriented along an insertion direction (42) and have a load application device (28) that can be moved along the guidance columns (20), above the lower mold part (8), wherein the load application device (28) has an upper mold part (22) on its side that faces the lower mold part (8), on which one or more pressure plates (24) can be introduced or are introduced into one or more recesses (12) of the lower mold part (8), wherein the load application device (28) is connected with the pressure plates (24) by way of pressure rams (26), wherein an upper guidance element (38) is arranged between the load application device (28) and the pressure rams (26), wherein the upper guidance element (38) interacts with a lower guidance element (40) arranged on at least one of the retaining braces (16), in such a manner that during the production of the concrete blocks comprising filling of the lower mold part (8), compression, and unmolding, the load application device (28) is constantly guided, relative to the lower mold part (8), in a plane perpendicular to the insertion direction (42), wherein the upper guidance element (38) and the lower guidance element (40) are in engagement throughout the production.
