A cooling device for cooling a plurality of preforms or tubular containers, preferably exiting from a rotary injection molding apparatus, the device comprising—a first longitudinal support member () defining a longitudinal axis Y and having a first longitudinal surface () and a second longitudinal surface () opposite to the first longitudinal surface; —a plurality of cooling tubes (), each adapted to receive a respective preform to be cooled, said cooling tubes being arranged on said first longitudinal surface () in sequence along the longitudinal axis Y and each cooling tube defining a perpendicular axis thereof with respect to said longitudinal axis Y; —at least one first connection pin () protruding from said second longitudinal surface () for a quick coupling to a second longitudinal support member (), preferably adapted to be arranged on a rotary cooling apparatus.

A cooling and retaining pin () for cooling, by air blowing, and retaining, by air suction, a plastic preform, the pin comprising a body (), defining a longitudinal axis and having a first opening () at a first end thereof, coaxial to said longitudinal axis and adapted to be connected to a handling station; a movable element () adapted to slide at least partially inside said body; at least one air passage gap provided at a second end of the body or at said first end; wherein the movable element () is adapted to move from a first position, to which a first air passage section corresponds, to a second position, to which a second air passage section corresponds, which is smaller than said first section, so as to adjust a blowing air flow during the cooling step and a suction air flow during the step of retaining the preform.

A blow mold provided with a locking system for mutually locking each half-mold with the related half-mold holder, thus allowing a simpler and quicker replacement of the side half-impressions of the mold. The blow mold of the invention provides for the side half-impression of each half-mold to be fixed in a cavity of the corresponding mold holder by actuating at least one quick coupling device comprising a bar () inserted in one of the two longitudinal edges of the half-mold holder () and adapted to move only by rotation about an axis thereof; actuation means () adapted to actuate a rotation of said bar; and at least one locking fin () fixed along said bar () and adapted to move, by rotating the bar (), from an unlocking position to a locking position in which said locking fin interacts with the respective half-mold ().
