A kind of equipment for manufacturing cast magnesium structural parts of large spacecraft

Abstract

The present invention relates to a kind of equipment for manufacturing cast magnesium structural parts of large-scale spacecraft, which comprises a sand box unit, a sand core unit and a casting unit, and the sand box unit is composed of a plane sand box, an outer round sand box, a first inner round sand box and a second round sand box Two inner sand boxes; the sand core unit is composed of base sand core, inner sand core and surface sand core; the casting unit is composed of drainage sprue and sprue basin. Through the effective combination of the sand box unit, the sand core unit and the casting unit, the equipment effectively uses the combination of the sand box and the sand core to realize the purpose of a set of sand box being simple, efficient, and occupying less land, and solves the problems in the prior art .

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...
