In recent years, as perforated bricks are widely applied in the fields of water and soil conservation and environmental beautification, the existing block making machine has the function of producing the perforated bricks through improvement, when the perforated bricks are produced, a driver pushes a core rod to enter a mold box from one side of the mold box through a hole on the mold box, the core rod passes through mixed materials in the mold box and then extends out from the hole on the other side of the mold box, and thus the perforated bricks can be pressed. However, because the block making machine produces the blocks by adopting a vibration compaction mode, the core rod is easy to bend and deform due to vibration, so that the diameter of the bricklaying hole close to one side of the mold box is inconsistent with the diameter of the bricklaying hole close to the other side of the mold box. In addition, because the mold box is large in size, the core rod needs to have enough length to penetrate through the whole mold box, the long core rod is easy to bend in the process of penetrating through the mold box, especially the front end of the core rod bends downwards due to the action of gravity, so that the core rod is difficult to align with a hole on the other side of the mold box, and when the core rod cannot be aligned, the core rod abuts against the mold box or a guide piece on the mold box, so that the mold box or the guide piece is deformed and damaged.
