Pneumatic structure of pillow pouring mold

The utility model discloses a pneumatic structure of a pillow pouring mold, relates to the field of pillow pouring, and aims to solve the problem that the use efficiency of a device is reduced due to the fact that an upper mold and a lower mold cannot be attached due to the fact that a common pneumatic structure of a pouring mold is easy to deviate after being used for a long time. A lower mold is mounted on the inner wall of the bottom end of the machining box, a hydraulic rod is fixedly mounted on the inner wall of the top end of the machining box, an upper mold is fixedly mounted at one end of the hydraulic rod and attached to the lower mold, a mounting plate is mounted in the lower mold, and limiting grooves of the same structure are formed in the inner walls of the two sides of the machining box correspondingly. The two limiting grooves are symmetrically distributed, and limiting blocks are fixedly installed on the two sides of the upper mold. The pneumatic structure limiting device is novel in structure
