Abstract：
Taking a die casting mould of a company as an example, the deformation failure of the mould core was analyzed, and the countermeasures to reduce the failure of the mould core were put forward. The results show that the main types of core failure are core fracture, core bending deformation, size deviation and adhesion. Among them, the failure of core bending deformation is mainly caused by the impact of metal motel circulation and the accumulation of small deformation.The failure of core is mainly the failure of bending deformation and the failure of thermal fatigue crack rarely occurs.
