Is it possible to 3D make this injection mold?

I have this project in college. I have to make this plastic injection mold of a thermos cap, but my teacher is that kind that just puts pressure on students without caring too much about how they gonna do what they have to do, so he gave us just a 2D on paper and we have to do the 3D and 2D in a software. We have some materials but none of them are too helpful and it's kinda hard for me identifying the parts of it because we barely did something like this. We have made some molds, but more basic ones.
Can I please get some help here please?
