The present invention relates to a pinnacle mold assembly in which a pinnacle mold with cutting blades capable of cutting various thin materials are combined with a scrap storage tray capable of storing scraps which are separated from the thin materials by being cut by the pinnacle mold. The pinnacle mold assembly of the present invention includes: a pinnacle mold; a scrap storage tray coupled to the pinnacle mold; and scrap guide members arranged on the scrap storage tray. The pinnacle mold includes: supporting plates; cutting blades embossed on each of the supporting plates to cut a thin material partially; and scrap inlet holes passing through each of the supporting plates inside the cutting blades such that scraps separated from the thin material by the cutting blades can flow into the scrap inlet holes. The scrap storage tray includes: scrap guide holes respectively connected to the scrap inlet holes such that the scraps which are separated from the thin material to flow into the scrap inlet holes can pass through the scrap guide holes; and scrap storage chambers configured to store the scraps passing through the scrap guide holes. The scrap guide member is arranged in the scrap storage chamber to guide scraps such that the scraps passing through the scrap guide holes can diagonally flow into the scrap storage chamber.
