ECO-MOLDING APPARATUS FOR MANUFACTURING PISTON, MOLDING APPARATUS FOR MANUFACTURING PISTON, AND PISTON MANUFACTURING METHOD

摘要

The present invention relates to an eco-molding apparatus for manufacturing a piston, a molding apparatus for manufacturing a piston, and a piston manufacturing method, by which parts of a piston can be molded to reduce the weight of the piston. The present invention may comprise: an eco-molding part rotated along an arch-shaped orbit toward an eco-part of a piston by an arch-shaped guide slot so as to mold the eco-part of the piston; and an eco-molding driving part connected to one side of the eco-molding part so as to move the eco-molding part forward and backward in a direction perpendicular to the central axis of the piston.
