How to close these two holes?
Attach file please.
It's an undercut. Creating that as a standard shutoff would allow plastic to flow into the holes and eliminate the feature all together. You would need a core insert or slides.
Please attach the file of your solution.
Orrr, you could do a little research on undercuts, core inserts, slide-by shutoffs, slides or just molding in general.. The internet is a powerful tool and there are plenty of video tutorials on how to create core shutoff features.
I found an audiovisual aid on above topic but the problem is voice is not clear enough to understand.

that one doesn't show any undercuts.
this is a little overkill but gives you a good reference of the whole process.
*specifically at about the 7min mark when he starts creating cores for the submerged feature..

Please put forth more effort on your own behalf.
Just to illustrate, you would still create a shut-off surface on one of the openings of each of those holes. From there, you would have to incorporate a slide into your mold. The image below shows side cores (created with Core tool) in a sample part that I created a tool for. The slide-cores move perpendicular to the main core and cavity. Typically these will move first and then the core/cavity will separate.
It is highly appreciated if you could attach the file.
My apologies Maha but this is not my file to publish. The pictures shown by both Paul and myself should get you on the right track. I'm on a 2016 computer and can't open your source file right now.
I will expect your file later.
Please attach the file.
Do you know any e-Book in this subject?
Injection Mold Design Engineering is available as an e-book (kindle).
Do you have any public libraries near you? Books on the subject can often be found there as well.
I have a Germany edition for molding handbook, do you need it? I will send to you.
I do not know Deutsch language.
Germany designers translate it to English buddy...
Please send me if it is a e-book.
