Abstract
The present invention relates to an eco-mold apparatus for manufacturing a piston, a mold apparatus for manufacturing a piston, and a piston manufacturing method, which mold each part of a piston while decreasing the weight of the piston, and the apparatus may comprise: a first eco-mold part which may move forward or backward in a first direction to shape a portion of an eco-part of a piston; a second eco-mold part which may shape-match with the first eco-mold part to mold another portion of the eco-part of the piston; and a piston pickup part which picks up the piston over the second eco-mold part, so that the piston pickup part can separate the piston from the second eco-mold part.
