Abstract
A spray system for a molding process applies mold release agent to a surface of a mold to assist in release of a molded article from the mold. The spray system includes a spray head attached to a frame member. The spray head is vertically movable with respect to the frame member. The spray head includes a plurality of nozzles for outputting mold release agent. A mold release agent source provides mold release agent to a mold release dosing device. The dosing device provides select quantities of mold release agent through a conduit to a manifold mounted on the spray head. The manifold includes a plurality of valves leading to a plurality of nozzles. Then the dosing device outputs a predetermined amount of mold release agent to the manifold through the conduit. In operation, the spray system provides an air input to the dosing device to remove any mold release agent therefrom and to flush mold release agent from the conduit and manifold outwardly through the nozzles. Thus, a precise quantity of mold release agent is obtained in the dosing device and provided to a surface of a mold.
