(1) placing the indoor shell (14) on a lock hole (141) punching lower die (42) core to punch out a lock hole (141) and a first vent hole (142); placing the sliding sheet (15) on a core (23) of a lower mounting hole punching die (42) to punch a first mounting hole (151) and a second vent hole (152);

(2) placing the indoor shell (14) obtained in the step (1) on a vent hole punching die of the indoor shell (14), enabling the punched vent holes I (142) to be matched with a positioning table (333), so as to punch a plurality of vent holes I (142) in order, moving different vent holes I (142) to be matched with the positioning table (333) according to the length of the indoor shell (14), and punching the required number of vent holes I (142); punching a plurality of second vent holes (152) on the sliding sheet (15) in the same way;

(3) placing the soundproof cotton (17) on a punching die of the soundproof cotton (17) so that one end of the soundproof cotton (17) is located in the second positioning groove (46), and preferentially punching a corresponding lock hole (141) and a corresponding vent hole (142) in the soundproof cotton (17);

(4) then placing the soundproof cotton (17) obtained in the step (3) into the first positioning groove (45), enabling the first vent hole (142) in the soundproof cotton (17) to be clamped into the first positioning block (423) at the end part of the first positioning groove (45), and enabling the upper die (41) to press down to punch out the remaining first vent hole (142) in the soundproof cotton (17);

(5) putting the tail end of the soundproof cotton (17) obtained in the step (4) into a positioning groove III (47), so that a vent hole I (142) at the tail end of the soundproof cotton (17) is clamped into a positioning block, and the upper die (41) is pressed downwards to cut off the tail end of the soundproof cotton (17);

(6) placing the cover plate (16) into a punching die of the cover plate (16) to punch a third vent hole (161), moving the cover plate (16) according to the length of the cover plate (16) to clamp the third vent hole (161) into the positioning column (512), and sequentially punching the remaining third vent holes (161);

(7) cutting a coiled filter screen sheet for manufacturing a first filter screen (12) or a second filter screen (18) into a proper width by using a tool, installing the coiled filter screen between a first baffle (721) and a second baffle (722), enabling the end part of the filter screen to pass through a first pressing roller (62) and a second pressing roller (63), adjusting the gap between the first pressing roller (62) and the second pressing roller (63), and rolling the two side edges of the filter screen by slowly drawing the filter screen;

(8) and (3) sequentially assembling the window type ventilator (1), and inserting the rolled filter screen into a corresponding position.
