Surface and solid can not be selected as one while using split line command.
Why don't you create the mold only using the solid?
When you have the core you can extrude cute the current Surface volume and put your punched id there.

By avoiding the extra Surface and only taking the solid part into consideration, You can easily create molds like the attached photo.

Before jumping into mold, don't Forget to add draft angle as well as fillets on the Corner. These are the normal practice.
Draft angle helps you to pull off mold cavity/core easily after material injection.
Fillets ensures smooth material flow inside the mold and produces part without sharp Corners.

Dear Sahedul Abedin ,

In the second, according to your advice , I have made another mold.

Better under standing i am going to attached two image by which you can get better.

Image 1 original : Mold made by you punch is perfect at both side.

Image 2 problem one : Error one

Problem is, you have use combine part for two times and in second one at the opposite side when i have try to combined, i can not select the portion that you have select.Directly all split become select.

I didn't use that step .Result as shown in image.One side having step over punch and impression same on mold.

And please guide me why you have done surface extrude 2.You choose direct is perpendicular to front plan and distance is 10mm .Why it is necessary.I also put 10mm in my current project. How you brought the value of the 10 ?? It is random ??
