Injection molding tool

摘要

An injection molding tool is used to produce plastic parts such as toothbrush bodies or razor handles, for example. The tool has a stationary center mold block and a pair of outer mold blocks. The center mold block has two parallel opposed molding faces joined by two parallel opposed side faces extending perpendicular to the molding faces. The molding faces have parallel partial mold cavities formed therein and the outer mold blocks each are associated with one mold face of the center mold block and each have a molding face with parallel partial mold cavities formed therein which together with corresponding partial mold cavities of the associated mold face of the center mold block form complete mold cavities. Holders are indexed alongside the peripheral faces and around corners formed between the peripheral faces to hold and transport molded parts alongside the peripheral faces of the center mold block.

主权项

1. An injection molding tool for producing molded plastic parts, comprising:
a stationary center mold block and at least one movable outer mold block, the stationary center mold block having peripheral faces joined by corners, at least one of the peripheral faces being a molding face which cooperates with the at least one movable outer mold block, the molding face and the at least one outer mold block defining mold cavities for molding molded parts; at least two holders which are adjacent to each other and are movable with indexing steps of differing size relative to each other and closely alongside the peripheral faces and around the corners formed between the peripheral faces of the stationary center mold block for holding and transporting molded parts alongside the peripheral faces of the stationary center mold block; core members for a molded part connected to the holders; and wherein each holder is configured to lift each core member out of the mold cavities just an amount of space necessary for a free movement of the holders with the molded parts thereon and wherein each holder is substantially parallel to each peripheral face during indexing.
