Abstract
The invention discloses a complex thin-wall aluminum magnesium alloy casting and a casting method thereof. The casting method comprises the following steps that S1, a three-dimensional model of a pre-printing resin sand casting mold is designed, a resin spraying 3D printing device is adopted for carrying out 3D printing with resin sand as a raw material to obtain a resin sand casting mold with a casting mold cavity and a rigging system mold cavity; S2, a metal sand box sleeve matched with the appearance of the resin sand casting mold is mounted on the resin sand casing mold, and a clearance of50 mm to 300 mm is reserved between the resin sand casing mold and the metal sand box sleeve; S3, the clearance between the resin sand casing mold and the metal sand box sleeve is filled with a filler, hardening is carried out, and a pre-pouring casting mold is obtained; and S4, the pre-pouring casting mold is placed in a vacuum difference pressure casing device to finish casting, and the complexthin-wall aluminum magnesium alloy casting is obtained. The casing method of the complex thin-wall aluminum magnesium alloy casting achieves effective combination of a resin spraying 3D printing technology and the vacuum difference pressure casting technology, and has the advantages of being short in period, high in precision, good in quality, and excellent in cost.
Description
technical field [0001] The invention relates to the field of aero-engine castings, in particular to a complex thin-walled aluminum-magnesium alloy casting. In addition, the present invention also relates to a casting method comprising the complex thin-walled aluminum-magnesium alloy casting. Background technique [0002] Resin spraying 3D printing refers to slicing the 3D model, and the printing head of the equipment is precisely positioned according to the shape of each layer of the sliced file, and the resin is sprayed onto the molding sand, which is accumulated layer by layer and naturally cured to form the required 3D sand model. Laser sintering 3D printing technology refers to the printing method in which the resin is cured by laser and stacked layer by layer to form the required three-dimensional resin model. Different from sand molds and sand cores manufactured by metal molds in traditional sand casting, resin-sprayed 3D printing has the advantages of rapid trial p...
