The invention discloses a die with a front door opening and a rear door opening, an inner door ring and an automobile side wall. A machining cavity is formed when an upper die and a lower die of the die are folded; the machining cavity comprises an A column lower inner plate section machining part, an A column upper inner plate assembly section machining part, a B column inner plate section machining part, an inner doorsill assembly section machining part and a side wall rear inner plate assembly section machining part, and the adjacent machining parts communicate with each other. A door ring shape with a front door opening and a rear door opening is defined by the A column lower inner plate section machining part, the A column upper inner plate assembly section machining part, the B column inner plate section machining part, the inner doorsill assembly section machining part and the side wall rear inner plate assembly section machining part. The blank of the column A lower inner plate section, the blank of the column A upper inner plate assembly section, the blank of the column B inner plate section, the blank of the inner doorsill assembly section and the blank of the side wall rear inner plate assembly section which are connected together through tailored blank laser welding are integrally formed in a hot stamping mode through the die, so that the inner door ring has the advantages of being high in integration degree, light in weight, high in strength and easy to machine.
