Abstract:
A molding apparatus adapted for forming a golf ball having one or more deep dimples that extend at least to the next layer, said apparatus comprising:an upper mold having a first hemispherical molding surface that defines (i) a hemispherical molding cavity, and (ii) at least one aperture defined along said first molding surface, said upper mold further having in each of said apertures, a selectively positionable pin having a distal end that may be extended into said cavity or retracted from said cavity, wherein said first hemispherical molding surface further defines at least one outwardly extending projection having a height as measured from said first molding surface, to from about 0.002 inches to about 0.140 inches; a lower mold having a second hemispherical molding surface that defines (i) a hemispherical molding cavity, and (ii) at least one aperture defined along said second molding surface, said lower mold further having in each of said apertures, a selectively positionable pin having a distal end that may be extended into said cavity or retracted from said cavity, wherein said second hemispherical molding surface further defines at least one outwardly extending projection having a height as measured from said second molding surface, of from about 0.002 inches to about 0.140 inches, wherein said upper mold and said lower mold are adapted to engage each other such that said first molding surface and said second molding surface form a generally spherical molding chamber; whereby said pins in said apertures defined in said upper mold and said lower mold extend into said molding chamber a distance of from about 0.002 inches to about 0.140 inches as measured from said respective first and second molding surface, said pins remaining in said extended position during a molding operation so as to form a corresponding number of deep dimples in said golf ball.
