Casting device for aluminum alloy thin-walled piece water-cooled metal shell mould

Abstract

The invention relates to the technical field of metal casting, in particular to a casting device for an aluminum alloy thin-walled piece water-cooled metal shell mould. The casting device for the aluminum alloy thin-walled piece water-cooled metal shell mould comprises a metal shell mould, and is characterized in that the thermal capacity of the metal shell mould is reduced, the cooling speed of an aluminum alloy thin-walled piece in a mould filling process is reduced, and the mould filling capacity of a molten liquid in the device is improved by reducing the wall thickness of a casting mould;after the mould filling of the aluminum alloy thin-walled piece is completed, the metal shell mould is subjected to quick water cooling so as to improve the cooling speed of the molten liquid in a solidifying process, accelerate the solidifying rate of a casting, refine the structure of the aluminum alloy thin-walled piece and improve the mechanical properties; the casting device for the aluminumalloy thin-walled piece water-cooled metal shell mould solves the difficult problems that the mould filling of the aluminum alloy thin-walled piece is difficult to perform and the mechanical properties are poor; moreover, the metal shell mould can also be reused; the production efficiency is improved; and the manufacturing cost and the environmental pollution are reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of metal casting, in particular to a water-cooled metal shell mold casting device for aluminum alloy thin-walled parts. 【Background technique】 [0002] With the renewal of revolutionary technology and the development of industrial technology, aluminum alloy thin-walled parts are more and more widely used in the fields of automobiles, weapons, aerospace and other fields, and the production requirements for the performance of aluminum alloy thin-walled parts are also getting higher and higher. Modern industries generally adopt measures such as reducing the structural weight of aluminum alloys and improving the mechanical properties of aluminum alloys to improve the performance of thin-walled parts. Aluminum alloy has the characteristics of low structure density, high mechanical strength and high rigidity, which can reduce the overall weight of car body and aerospace material parts, and improve the overall pe...
