That is against HN's rules. In fact, it's the one thing that's important enough to be in both the site guidelines and FAQ. HN users feel extremely strongly about this.
Q: Can I ask people to upvote my submission?
A: No. Users should vote for a story because they personally find it intellectually interesting, not because someone has content to promote. We penalize or ban submissions, accounts, and sites that break this rule, so please don't.

Don't solicit upvotes, comments, or submissions. Users should vote and comment when they run across something they personally find interesting—not for promotion.
