How to convert polygons in single shapefile into rasters with model builder

I'm having a problem of overlaid polygons in a single shapefile. I want to convert all polygon to raster then sum the value of any polygon which area overlaid. if I convert this shape file into raster, it chose only the first polygon which is overlaid another to represent to value of cells. I'm thinking if I want to sum value of overlaid polygons together, I should separate each polygon to different shapefile then convert it to raster and use raster calculator to sum all rasters but there's about 15000 polygons within single shapefile, so I cannot manually select and convert it to raster one by one. I'm thinking about iterator in model builder but i 'm very new with model builder. So if anyone can help to solve the problem i explaint above? Your help is very much appreciated.
