Ashton announced his final squad a day earlier than expected having seen his side fall to a 21-15 defeat to France on Saturday evening.
Tigers captain Corry is set to play in his third World Cup following appearances in 1999 and 2003, while Hipkiss and Chuter have been selected for their first tournament. Moody and Kay both won winners medals in Australia last time around and will be hoping for similar success in Paris on October 20.
Hipkiss, who made his England debut during the record victory over Wales at Twickenham just over a week ago, is named in a group of 14 backs, with Corry, Chuter, Kay and Moody among 16 forwards.
Tigers acting head coach Richard Cockerill said: "I am very happy for all of the guys who are involved in the England squad. We wish them all the best of luck.
"Dan did well against Wales and showed he can play at that level," added Cockerill. "As a country, we should get behind the squad, be positive and encourage them to do well."
Mike Tindall, Charlie Hodgson, Nick Abendanon, Danny Cipriani, Toby Flood, James Haskell, Kevin Yates and Tom Palmer all miss out, with Tindall and Hodgson both failing to recover from injury in time for the start of the competition.
Having narrowly lost out to the French on Saturday, England will name their 22 on Tuesday for next weekend's re-match as they get ready for their final warm-up fixture before they begin the defence of their world crown against the USA on September 8.
