A method of operating a mold-spraying apparatus of a molding apparatus, the molding apparatus having:
- (a) a fixed platen, (b) a movable platen, (c) a platen-moving mechanism being configured to move the movable platen relative to the fixed platen, and (d) a mold having molding surfaces being supported by the fixed platen and the movable platen, and the mold defining a mold envelope, the mold-spraying apparatus having:
- (i) a spray nozzle, (ii) a rotatable shaft being rotatably mounted to the fixed platen, the rotatable shaft being attached to the spray nozzle, (iii) a camming surface being movable with the movable platen, (iv) a cam follower being attached to the rotatable shaft, and the cam follower being engageable with the camming surface, the method comprising:
- actuating the platen-moving mechanism so that the movable platen may be moved;
- and
- engaging the cam follower with the camming surface so that the rotatable shaft and of the spray nozzle may be rotated, and the spray nozzle becomes:
- (i) rotated proximate of the molding surfaces to spray the molding surfaces when a movable portion of the mold being attached with the movable platen becomes separated from a fixed portion of the mold being attached with the fixed platen, and
- (ii) rotated to a position outside the mold envelope before the movable portion of the mold makes contacts the fixed portion of the mold.
