I want to do the sand casting of cast iron of the model. But i dont know from where i give the parting line.
I think you'll have the parting line along the blue edges in this image.
For it to work, you'll need to also:
1. Combine all six bodies together into a single part.
2. Add draft angles to the model faces so the pattern can be pulled from the sand.
3. Add fillets to the part. No sharp edges.
4. The left side of the part is a massive chunk of iron compared to the rest of the part. That could cause problems.
5. Scale the model to account for material shrinkage.
6. Anticipate the need for post casting operations like grinding and drilling, and milling to form some of your holes.
i want to know dat where the parting line will come in the handle
can you make mold for me so dat i know how u place the handle in the mold
i want to do in practical...so i want to know..how we can do the casting of this handle.
I don't think the part is ready to be cast, but where were you planning to add the sprue and vent? That will help finalize the parting line.
i dont know dear..all I have to decide. I have to do the sand casting of this handle.. So I am confused dat how the casting will be done
You could do something like this example.
I've only made a few sand castings, so I'm far from an expert. I hope you've made some before, because this part is going to be tricky. It still needs fillets, draft angles, a fill, vents, and maybe two pins to form the holes.
I think some features would be better machined after making the castings, but I guess you can try it and see how it comes out.

The file was made in SolidWorks 2016. There is not much benefit in the file. You'll need to make the pattern for sand casting, ram sand around it, remove the pattern, close up the mold, and finally pour your metal into it. I just made the model so you'd see where the parting line could be.
The file needs more/larger fillets, and draft angles added to support the removal of the pattern from the sand.
Don't forget step 5 from above, which was to first scale your pattern to account for any shrinkage in the casting.
Dear in which software u make the mold.
In my opinion your part design is still far from being ready for casting.
You Need to decide the parting line first.
You Need to add draft angle first. I see None in the existing model.
Next you Need to decide where the parting line will be. That will also effect where you are allowed to put fillet and where not. One possibility could be the Image following, but Keep in mind the red Zone which creates an undercut.
