How to request an extension for submission to a conference?

I am writing a few research papers for an upcoming conference and things have been going decently. But I could really use more time to analyze my papers.

I am new to writing and this entire conference process, however - How should I e-mail the organizer requesting a deadline extension?

Hi Dr. Bobster,

I would like you to extend the deadline for the
international conference on procrastination.

Sincerely,
Procrastinator

Also if it helps: I should make this extra polite because this is also someone of high influence.

It looks like for the past versions of this conference, they gave at least a week extension. This is a fairly well known event, though it doesn't usually end up presenting any ground breaking research.

It looks like the past few events had extensions, its a well-known event but not too crazy. There's no way I can finish this with the other things I have..
