Title:
SPRAY NOZZLE TIP AND METHOD OF MANUFACTURING THERMOSETTING ERSIN USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2004/076072
Kind Code:
A1
Abstract:
A spray nozzle tip having excellent swirl flow generating efficiency, and capable of increasing the spreading of the spray pattern of sprayed thermosetting resin, reducing the sizes of atomized liquid drops, reducing the entanglement of air bubbles, and spraying the thermosetting resin on a mold to provide a thin and uniform thermosetting resin-molded product with excellent mechanical strength, comprising a casing body in which a thermosetting resin flow passage is formed, an orifice part installed at the spray opening part of the casing body, a core part installed on the opposite side of the spray opening part side of the orifice part, and a swirl flow formation chamber formed between the orifice part and the core part and communicating with the orifice outlet of the orifice part. A swirl groove communicating with the inner peripheral wall of the swirl flow formation chamber in the tangential direction is formed in the orifice part in the vertical direction relative to the axis of the orifice outlet.
