As shown in fig. 1, the present embodiment provides a block blank production mold, which can be used to form a block blank 100, and the block blank 100 can be cut to obtain blocks required for construction.

Specifically, the block blank production mold comprises a mold body 1, wherein the mold body 1 is a cuboid box structure, the top of the mold body is open and used for injecting slurry, and a molding space of the block blank 100 is formed in the mold body 1. The slurry is solidified and formed into a cuboid block blank 100 in the die body 1, and the block can be formed by transversely and longitudinally cutting the block blank 100. Wherein, the cutting of the block blank body can adopt a linear cutting mechanism.
