Abstract:
A method for molding an O-ring retainer in a molded plastic part comprising:a) providing a first mold half having a first mold half axis, a cavity portion, and a plurality of first and second circumferential teeth axially displaced and about the first mold half axis with cavity defining surfaces, the first teeth having radial ends outward of the first mold half axis with surfaces with planar portions closest to the first mold half axis; b) providing a second mold half having a second mold half axis, a cavity portion, and a plurality of third and fourth circumferential teeth axially displaced and about the second mold half axis with cavity defining surfaces angularly displaced about the second mold half axis to mesh with the second and first teeth, respectively, of the first mold half when mated therewith, the second mold half third teeth having radial ends outward of the second mold half axis with surfaces with planar portions closest to the second mold half axis; c) translating the first mold half relative to the second mold half along respective axes to thereby mate the first and second mold halves to form a cavity for the molded part; d) molding the part within the cavity to thereby form a part with a plurality of first and second axially displaced surfaces for retaining an O-ring.
