Problems solved by technology

For composite material casting, the problem of settlement and agglomeration is often the first to be considered. Therefore, composite materials need to be continuously stirred during casting. The equipment described in patent 02115638 is only suitable for the preparation of aluminum alloys, not for aluminum alloys. Forming of matrix composites

Abstract

The antigravity vacuum sucking cast apparatus for aluminum base composite material used in casting field includes smelting plant, vacuum sucking cast plant and gas path. The smelting plant has stirrer, crucible stage, protecting gas channel, heat insulating layer and radiation-proof layer in the crucible mouth. The vacuum sucking cast plant has partition plate with sealed sleeve, riser tube and sealing washer, backing board, shuttering fixing jacket, shuttering, hoisting hook and ring, and vacuum channel connected to the gas path. The gas path has vacuum pump connected via the first cut-off valve to the vacuum tank, vacuum outlet and gas exhaust outlet connected via throttle valve and the second cut-off valve to the vacuum tank and vacuum gauge. The present invention has simple structure and convenient operation, and may be used in industrial production.

Description

technical field [0001] The invention relates to equipment in the technical field of casting, in particular to an aluminum-based composite material anti-gravity vacuum suction casting forming equipment. Anti-gravity vacuum suction casting belongs to the field of precision casting. It is used in the production of large, thin-walled and complex aluminum castings in aviation, aerospace, electronics and other industries. Background technique [0002] The preparation of particle-reinforced metal matrix composites mainly includes powder metallurgy, spray casting, pressure or non-pressure infiltration, stirring compounding, etc. After stirring compounding, complex castings can be directly formed, so this method has great potential. For castings with complex structures, large thin walls and high quality requirements, it is often difficult to form composite materials by ordinary gravity casting methods, and special casting processes such as vacuum suction casting and differential pre...
