Abstract

The invention provides a local high-enhancement cooled piston casting device which comprises a top part mold, a bottom part mold, a left mold and a right mold, wherein a top part mold cooling water cavity, corresponding to the throat position at the top part of a piston, is formed in the top part mold; a left mold parallel round hole cooling waterway, surrounding the inner side surface of the left mold, is formed in the left mold; a cooling waterway is formed in a pin hole of the left mold; a right mold parallel round hole cooling waterway, surrounding the inner side surface of the right mold, is formed in the right mold; and a cooling waterway is formed in a pin hole of the right mold. According to the local high-enhancement cooled piston casting device, with the addition of the cooling waterways at the left and right part of a piston pin hole respectively, the piston pin hole is accelerated to be cooled; as a combined type structure is adopted to a mold in the piston cavity to form the cooling water cavity, the bottom part mold is more simple in design and meanwhile, improves the cooling capacity of the inner cavity of the piston.

Description

technical field [0001] The invention belongs to the technical field of piston casting molds, in particular to a piston casting device with local highly enhanced cooling. Background technique [0002] The piston is one of the core components of the engine, and its performance is directly related to the overall performance and reliability of the engine. Therefore, more and more researchers are working on the design and improvement of the piston. The piston is also one of the parts that bear the most severe mechanical and thermal loads in the engine. The mechanical properties of the piston casting directly affect the reliability and life of the piston. Therefore, in order to improve the mechanical properties of the piston, it is necessary to improve the casting of the piston. performance. [0003] The solidification process of piston casting greatly affects the material structure and mechanical properties. For piston cast aluminum materials, the better the cooling conditions, ...
