Lightweight concrete hollow block pouring forming mold

The invention relates to a lightweight concrete hollow block pouring forming mold. The mold comprises a cross-shaped plate and an adjusting device arranged above the cross-shaped plate, and a beating device is arranged above a lifting air cylinder. According to the lightweight concrete hollow block pouring forming mold, through cooperation of a first strip-shaped formwork, first rectangular baffles and bolts, the first strip-shaped formwork and the horizontal sections of two first L-shaped formworks can be spliced, and locking is conducted through the first rectangular baffles and the bolts; through cooperation of a second strip-shaped formwork, second rectangular baffles, cylindrical pins and positioning rods, the second strip-shaped formwork can be spliced with the horizontal sections of two second L-shaped formworks which are bilaterally symmetrical, and locking is conducted through the cylindrical pins and the positioning rods, so that the size of the mold can be quickly and accurately adjusted, the mold
