Abstract

The invention relates to equipment for manufacturing a magnesium casting structural component of a large spacecraft. The equipment comprises a sand box unit, a sand core unit and a casting unit. The sand box unit is composed of a plane sand box, an outer circle sand box, a first inner circle sand box and a second inner circle sand box. The sand core unit is composed of a base sand core, an inner sand core and a surface layer sand core. The casting unit is composed of drainage sprues and sprue basins. According to the equipment, by means of effective combination of the sand box unit, the aims that a set of sand box is simple, efficient and small in occupied space are achieved, and the problems in the prior art are solved.

Description

technical field [0001] The invention relates to equipment for manufacturing large-scale spacecraft cast magnesium structural parts, which is used for manufacturing spacecraft propulsion module structure instrument discs, and belongs to the field of casting technology. Background technique [0002] Since the beginning of the 21st century, my country's aerospace industry has achieved considerable development, and the dimensions of spacecraft such as satellites are gradually increasing, and the platform structure is required to be lightweight. Among metal structural materials, magnesium alloys with the lowest density are widely used in large spacecraft platforms due to their good biocompatibility, highest specific stiffness and specific strength, excellent process performance, and good corrosion resistance. [0003] With the rapid development of my country's aerospace industry, in-depth exploration, the establishment of space stations, and the demand for large launch vehicles h...
