EXTRUSION MOLDING APPARATUS FOR MANUFACTURING WIPER BLADE

摘要

The present invention relates to an extrusion molding apparatus for manufacturing a wiper blade, and an object of the present invention is to provide an extrusion molding apparatus for manufacturing a wiper blade that does not require a separate assembly process by integrally molding a wiper rubber and a rail spring. Extrusion molding apparatus of the present invention for achieving the above object is an extruder for supplying by heating and pressurizing the resin material constituting the wiper rubber; A mold chamber coupled to the outlet of the extruder to accommodate the resin material introduced from the extruder is provided, and a spring inlet through which a rail spring enters the mold chamber is provided on one side of the mold chamber, and on the opposite side of the spring inlet. A molding extrusion port for extruding and molding a resin material is provided, and a spring guide groove through which the rail spring is inserted and transferred is provided in the molding extrusion port, and the wiper rubber molded through the molding extrusion port is provided in the transverse direction of the rail spring. Extrusion mold to be partially embedded; And it is configured to include a rail spring supply means for transferring the rail spring to pass through the extrusion mold.
