An air discharge structure for a mold assembly is provided to form exact shape of a product and improve the productivity of injection molding by preventing efflorescence. An air discharge structure for a mold assembly comprises a fixed side plate(20), a first mold plate(22) and a movable side plate(30). The fixed side plate is installed at the fixed side of a press. The first mold plate, having a first main core(26) corresponding to the shape of a product, is installed at the fixed side plate. The movable side plate is installed at the movable side of the press. A second mold plate(36) is installed at the movable side plate to selectively contact with the first mold plate, and has a second main core(40) with a cavity(38) corresponding to the first main core. An eject pin(50) is installed in a movable space formed by a spacer block(32) between the movable side plate and the second mold plate, and separates a product from the second main core.
