Sorry i might be wrong but i don't think if we have any OOTB feature for the lip creating (for both the mating components) but as an option you can use REUSABLE features or UDF for the same. Infact you can have a library of the same.
There are lot of mold part detailing features already in the REUSABL;E OBJECT LIBRARY.(snap locks etc.).
For the lip you can optionally create a 2-D sketch and use that for the sweep (for creating the lip).
