摘要：
A plastic injection mold which allows extracting the air from inside it during the injection process, and an extraction method, where the mold includes closing means, one or more injection cavities provided with at least one injection nozzle for introducing the hot material in a liquid state and at least one ejector device formed by a housing for an ejector pin responsible for extracting the part already molded, where an air duct connected to a vacuum pump or a suction device intercepts the housings of the ejector pins causing a suction of the air from inside the mold.
