Quick cooling structure for hot spot of die-casting die

The invention relates to the technical field of die-casting dies, and discloses a die-casting die hot spot rapid cooling structure which comprises a first fixed die splicing block and a second fixed die splicing block, the bottom face of the first fixed die splicing block is an upper binding face, the top face of the second fixed die splicing block is a lower binding face, the shape of the upper binding face is the same as that of a die-casting die cavity, and the shape of the lower binding face is the same as that of the die-casting die cavity. The lower binding face is tightly attached to the upper binding face. In the prior art, the cooling efficiency of a hot spot area of a product is lower than the cooling efficiency of other parts of the product, so that the technical problem of low product yield caused by non-uniform cooling efficiency of each part of the product is solved. The cooling efficiency of all areas of the whole product can be close, and the product yield is increased; according to the positi
