Lower die of hot stamping die

The invention relates to a low die of a hot stamping die. The lower die comprises a lower die body, wherein the lower die body is equipped with a cavity which fits the shape of a to-be-formed product;the lower die body is further equipped with a forming ring which is positioned around the cavity; an inner hole of the forming ring serves as the cavity; and the forming ring is made of a hard alloy.By adoption of the above scheme, the lower die of the hot stamping die has the beneficial effects that the finished product quality can be improved, the die maintenance frequency can be lowered, andthe machining cost can be reduced. 本发明涉及种热冲压模具的下模，包括下模本体，该下模本体设置有与需成型产品形状相适配的型腔，下模本体围绕型腔设置有成型环，该成型环的内孔即为型腔，成型环为硬质合金。采用上述方案，本发明提供种提高成品质量、降低模具维修频率、降低加工成本的热冲压模具的下模。
