Abstract

The invention discloses an automatic magnesium alloy low-pressure casting machine, and relates to the technical field of casting. The automatic magnesium alloy low-pressure casting machine solves theproblems that burning accidents are extremely prone to occurrence in the existing magnesium casting process, castings are prone to forming shrinkage porosity, and oxidation slag inclusion exists. Theautomatic magnesium alloy low-pressure casting machine comprises a casting mould running mechanism, a pouring platform, a working tank, a working tank motion trolley, a liquid rising pipe and a controller; the casting mould running mechanism moves at the upper end of the pouring platform in the horizontal direction, a casting mould is borne on the casting mould running mechanism, the working tankmotion trolley moves at the lower end of the pouring platform in the horizontal direction, the working tank is arranged on the working tank motion trolley, the two sides of the working tank are each provided with a working tank lifting mechanism, the working tank is lifted on the working tank motion trolley through the working tank lifting mechanisms, the liquid rising pipe is inserted into the pouring platform, an air inlet pipe and an air exhaust pipe are connected to the working tank, and the casting mould running mechanism, the working tank motion trolley and the working tank lifting mechanisms are connected with the controller. The automatic magnesium alloy low-pressure casting machine is used for magnesium alloy casting.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to an automatic low-pressure casting method for magnesium alloys. Background technique [0002] Magnesium alloy has the characteristics of low density and high specific strength, and has always been an important material preferred in the aerospace field. However, magnesium is an extremely active metal, and combustion accidents are prone to occur in the traditional casting production process, which has always been an obstacle that is difficult to solve in casting production. In the traditional magnesium casting production process, sand molds and free casting methods are used, which cannot accurately control the solidification process of castings, and defects such as shrinkage porosity and oxidized slag inclusions are easy to form in castings. And with the development of aerospace technology, the requirements for castings on aerospace vehicles are higher, which is reflected in the in...
