description The invention discloses a method for processing an integral concave mould of a universal joint. The method comprises the following steps: (1) processing an external mould: sawing materials, roughly turning a big circle and a middle circle of the external mould, thermally treating, finely turning and grinding before pressing, thermally pressing the big circle and the middle circle, finely turning an inner hole and grinding the inner hole; (2) processing an internal mould: sawing materials, roughly turning, thermally treating, finely turning, flatly grinding, roughly milling an inner chamber and finely milling the inner chamber; and (3) cold-pressing the processed external mould and internal mould, wherein 0.3-0.5% interference fit of the outer diameter of the internal mould is adopted between the internal and external moulds, thereby obtaining the integral concave mould of the universal joint. The invention discloses a new method for processing the integral concave mould of the universal joint. The integral co
