The invention discloses a high-pressure water injection type cooling casting mold. The high-pressure water injection type cooling casting mold comprises a fixed mold part and a movable mold part correspondingly cooperating with the fixed mold part. The fixed mold part comprises a fixed mold base and a fixed mold body integrally formed with the fixed mold base, and a heat exchange cavity is formed in the fixed mold body. An annular water storage tank is formed in the outer side of the end, close to the fixed mold body, of the fixed mold base, an end sealing plate with the horizontal plane consistent with that of the fixed mold body is welded to the outer portion of the annular water storage tank, a water spraying mechanism is further welded to the upper end of the side face, facing the fixed mold body, of the fixed mold base, the annular water storage tank communicates with the heat exchange cavity, and the heat exchange cavity communicates with the water spraying mechanism. After the movable mold part moves, the movable mold part correspondingly cooperates with the fixed mold part, then casting materials are injected through the fixed mold part, and forming is conducted between the movable mold part and the fixed mold part; and the annular water storage tank, the heat exchange cavity and the water spraying mechanism in the fixed mold part form a total cooling water channel so that the cooling efficiency of a casting and the product quality of the casting can be improved.
Description
technical field [0001] The invention relates to a casting mold for high-pressure water injection cooling and its application method. Background technique [0002] Metal mold casting, also known as hard mold casting, is a casting method in which liquid metal is poured into metal molds to obtain castings. Cast molds are made of metal and can be used repeatedly (hundreds to thousands of times). The castings that metal mold casting can currently produce still have certain restrictions in terms of weight and shape. For example, ferrous metals can only be castings with simple shapes; the weight of castings should not be too large; Thick can't cast out. [0003] In order to solve the defects of shrinkage cavity, shrinkage porosity and coarse grain in the cooling process of metal castings, and improve the process yield, it is necessary to take technological measures to adjust the cooling speed of castings. According to the structure of the casting, the commonly used technological...
