The question should be: Who wants to do my homework for me? You haven't even tried. I used more time to my post than you did.
..you'd probably need have a cavity/core/insert and locating pins.. and remove (add material) for the post machining (which is on another plane).
Paul. the problem in this case is the cavity. It must be split so that you can pull out the model.
Like you see in cavity are undercuts:
Well, unless we use the lost wax method. And the removal of holes and planned surfaces, allowances for shrinkage, etc. As I wrote, it looks like a university task, so let the future engineer work his head.
In addition, the procedure for making the core and the cavity of the mold is carried out very quickly and simply (in this case)
..yeah, he mentioned "sand" so I would guess there is more to this story... the part does not have any draft, the top holes are at a angle, the side holes would need to be filled (and post c-sunk and drilled) so,.. imagine the core would need to be either loaded carefully at a angle or as separate insert and pinned/locked into position.... and yes, lost wax could be a option.
Insertion of the core is a smaller problem (and not our ), the cavity must be divided and opened sideways to pull out the model after filling the mold with sand. After divide cavity we don't have problem with core insertion.
I have doubts.

the rest of the pieces are missing, the link has the gross product.
See attached video.
can you examine this topic.
ömür tokman You have complicated this form unnecessarily. The holes must be removed. Then they are processed. Besides, as I see above in Roberto's post, this is only part of the model.

My first answer is for the first part. my second answer is for the second question. I did not understand where the problem is.
What I mean is that if you first remove the holes (which are then processed anyway) it will simplify your mold. Just split cavity and inserted core.

In this way (you need to give a "draft" in the direction of the blue arrows):
First make plane as screenshot:
Use id for make split line"
supporting the core, negative angle , what do you think?
do the dividing line like this.
Its no problem. Core and Cavity is molding separately. Split lines not must "colinear".
Sorry ömür tokman but if you don't have experience, (you wrote about his above) don't mislead others. Your split line is possible but unnecessarily complicates the mold.
I thought so, but negative angle core.
Above I showed you how make properly core split line
I'm sorry, but I couldn't.
