The present invention relates to a support block with individual hollow sections, for a machine for forming glass objects, and to its manufacturing method. The support block comprises: a single-piece support body formed by a front wall, a rear wall and lateral walls, thus forming a hollow rectangular body; an intermediate wall and a plurality of cross walls located inside the internal periphery of the support body, in a grid arrangement, forming a first plurality of hollow sections aligned along the front wall and a second plurality of hollow sections aligned along the rear wall, each first hollow section and each second hollow section being aligned and disposed one behind the other; a support section for each first hollow section and each second hollow section, each support section being connected near to the bottom part of each of the walls forming each first hollow section and each second hollow section, to support the different mechanisms of the machine for forming glass objects; tubular cavities located in a vertical position for each plurality of cross walls, for inserting lubricating pipes or cables, the tubular cavities being formed between each of the cross walls located inside the periphery of the support body; and aligning means located in a bottom part of the support body, for aligning the support block with respect to a determined installation area.
