You can use ModelAdmin's get_readonly_fields method for this purpose. When the object is created, the obj is set to None. By overriding the method, you can change the read_only fields if obj is present or not.

def get_readonly_fields(self, obj):
    if obj:
       return ['field_1', 'field_2']
    else:  # When object is created
       return [] # no editable field
