Mold-spraying apparatus of molding system

For a molding apparatus having a fixed platen, a movable platen, a platen-moving mechanism configured to move the movable platen relative to the fixed platen, a mold having molding surfaces supported by the fixed platen and the movable platen, the mold defining a mold envelope, a mold-spraying apparatus, comprising:

• a camming surface movable with the movable platen;
• a rotatable shaft rotatably mounted to the fixed platen;
• a cam follower attached to the rotatable shaft and the cam follower engageable with the camming surface;
• and
• a spray nozzle attached to the rotatable shaft, actuation of the platen-moving mechanism urges movement of the movable platen and engagement of the cam follower with the camming surface urges rotation of the rotatable shaft and of the spray nozzle, the spray nozzle becomes (i) rotated proximate of the molding surfaces to spray the molding surfaces when the movable platen becomes separated from the fixed platen and (ii) rotated to a position outside the molding envelope before the movable platen contacts the fixed platen.
