"Would you like some orange juice?" "Do you like...?" is a general question about what you like, and not an offer. In this case, "some" doesn't fit.

If you are offering someone than you have to say : Would you like to have some orange juice ? And when ask someone's opinion then you have to say : Do you like orange juice? ( When talking (in general) before offering) Did you like the orange juice ? ( Asking opinion after having juice )

Would you like some orange juice ? is the correct question . we use would you like...? when we offer something
