You can use the option -regex to use regular expressions:

find . -regex '\./[0-9]+_[0-9]+\.zip'

If you need to delete the found files, use xargs (please make sure before deleting):

find . -regex '\./[0-9]+_[0-9]+\.zip'|xargs rm -f

If you not only want to delete but also get the number of deletions, you can do this:

find . -regex '\./[0-9]+_[0-9]+\.zip'|tee >(wc -l 1>&2)|xargs rm -f
