ABSTRACT:
The invention relates to a negative mold containing a plurality of mold portions which can be detached from each other. It functions in particular for the manufacture of shapes consisting of plastic. The two mold halves enclose a molding chamber receiving the material to be shaped. In the chamber is arranged at least one insert abutting at least one projection which together form the negative for a surface depression to be produced in the shape. On the insert a fastening shank is arranged with the transition region being located in the region of the associated mold portion surface and being formed as gradation. Thereby the insert in contact with the mold half covers completely the orifice of the opening containing the shank and, in addition, projects beyond the opening edge.
