problems with creating a mold.

[michdlc]

Good evening to all

I would need urgent help using solidworks for work and I am stuck with the creation of a mold from a piece, or tried to make the mold with the cavity command but I do not understand how to fix, I attach the file in question, if someone can give me a hand, please. Thank you.
