Injection molded housing, has bores with threads formed in an arc-shaped block around part of the hole

摘要

A wall of the component has one or more circular holes (14) and an axial extension of the hole is formed around the periphery of the latter by a block (16). The side of the block facing the hole has a circular arc (20) coaxial with the hole and a smaller radius than the hole. The arc extends /} 180 deg and threads (20) are formed in the arc during component injection. An Independent claim is made for injection tool for molding the claimed component with at least one threaded bore (14). One tool part has a circular cylindrical punch to form the hole of the threaded bore while a second tool part is located at the free end of the punch in the molding position. The second tool part has a cut-out which forms the block (16) and threads (20) and moves perpendicular to the first part in and out of the molding position.
