Abstract

This invention relates to a fast air ejecting system for an injection mold which mold is composed of a male mold and a female mold and characterized in that the female mold has a mold body on the medium of which an upper opening and a lower opening are provided, and a plurality of through holes are provided around the lower opening for inserting elastic members. The openings are used for setting and positioning a sprue bushing. The sprue bushing is composed of an upper body recessed slightly and a lower body through which a runner passes. An inner vent pipe and an inner pipe are provided on the upper body. Further, a vent pipe and a connector are pre-set on the mold body. Air in the runner can be ejected through an air ejecting means. The mold body has a further pipe through which an air blocking rod is inserted for controlling air to flow into the runner. Due to such a design, air bubbles would not be generated during injection, and thus quality of the product is ensured, thereby serving as a product completely conforms to the industrial utilization.
