Injection mold and method for stress-free removal of a sprue system on the injection mold

摘要

Disclosed is an injection mold, with a mold plate forming at least one mold cavity for producing a molded part, wherein the mold plate has a runner, which branches into the mold cavity to form an undercut sprue tunnel, wherein the longitudinal axis of each Angus tunnel follows the course of a helix. The invention also relates to a method for tension-free removal of undercut sprue systems on such an injection molding tool.
