Concrete block mold

The utility model relates to the technical field of concrete, in particular to a concrete block mold which comprises two bases, splash-proof ventilation assemblies are installed on the bases, moving assemblies are installed on the bases, and each splash-proof ventilation assembly comprises a workbench fixedly installed on the top of the corresponding base. The device comprises a workbench, two mounting rods are fixedly mounted at the top of the workbench, a mold body is fixedly mounted at the tops of the two mounting rods, a vibration motor is fixedly mounted at the bottom of the mold body, and a baffle is connected to the top of the mold body in a clamped mode. According to the concrete block mold, by installing the splash-proof ventilation assembly, the top of the mold can be shielded when a concrete block vibrates, air in concrete can be smoothly exhausted through the ventilation holes, the situation that the concrete splashes when the concrete is subjected to jolt ramming work is avoided, and by installin
