A method of producing a plastic molded part with an insert by injection molding uses an injection mold which includes first and second mold halves configured to form an injection molding cavity when closed. The first mold half includes a contour surface in which a linear vacuum slot extends. The linear vacuum slot is provided with transverse slots in order to form a band-shaped vacuum region, via which the insert is fixable to the contour surface by applying a vacuum. The method comprises inserting the insert into the first mold half, which is fixed to the contour surface by applying a vacuum to the contour surface by means of the band-shaped vacuum region. After the insert has been fixed, the plastic compound is injected into the injection molding cavity. After the plastic compound has solidified, the plastic molded part with insert is removed from the injection mold.
