发明名称 Mold assembly for manufacturing a plastic tub with holes
摘要 Disclosed is an integrally molded plastic washing machine tub having a circular bottom and annular sidewalls formed with drain holes, the drain holes being encircled by a tapered, raised annulus on the inner surface of the sidewall. The design of the drain holes allows removal of the tub from the mold following molding, and prevents the snagging of fabrics placed in the tub.
