Abstract
A ventilation device (10) for a motor vehicle includes a housing (12) made of plastics and at least one ventilation flap (14) molded to the housing (12). The housing (12) has an opening (24) in the connecting region of each ventilation flap (14). A mold for producing the ventilation device (10) includes two cores (26, 28), which in an injection position define the contour of a ventilation flap (14) and in a demolding position provide for demolding the molded part formed in the mold. In the injection position, an opening (32) is formed between the two cores (26, 28) in the connecting region of the ventilation flap (14). In a method for producing the ventilation device (10) by means of the mold, the ventilation flap (14) is molded to the housing (12) through the opening (24) in the housing (12).
