Luggage pick up at Beijing

Hi, my husband is Filipino and I am Brazilian and we are planning to go to Mongolia with a connection in China (Beijing) for less than 24 hours. We will have to travel on a different airline towards Mongolia (MIAT Airline) and so, the issue is that we will need to get our bags in BJ Airport. Do we need a visa just to pass through immigration and get our suitcases? Thank you!
