The utility model discloses an air tube subassembly for injection mold is assisted to air current, include: air tube cover, air tube cover are used for installing in mould cavity's mounting hole, and the air tube cover has first end and the second end along the orientation of admitting air, and the air tube is put in and is provided with along axially extended first centre bore, the air tube core, the air tube core is movably to be set up in first centre bore, and the air tube core includes core and core, and when the air tube core was in closed position, the core moved to the first centre bore in, stops up first centre bore, and the removal is when opening the position when the effect of air tube core at atmospheric pressure under, and the core moves to the first centre bore outside, the formation air feed circulated between the wall of core and first centre bore air flue, and spacing subassembly, spacing subassembly is used for carrying on spacingly in the opposite direction of orientation of admitting air to the air tube core. Because the activity of air tube core sets up, solved the gas shutoff problem of present fixed air tube, and the too little easy fracture problem of screw thread of activity air tube, production is stable, and is effectual.
