Abstract

The invention discloses a multi-furnace and multi-liquid-rise-pipe molten aluminum mold filling method structure for sand mold low-pressure cast gas-tight thin-walled shells. The multi-furnace and multi-liquid-rise-pipe molten aluminum mold filling method structure comprises liquid rise pipes and a thin-walled aluminum alloy casting, and is characterized in that a liquid flow tank is arranged above the liquid rise pipes in the horizontal direction; the two ends of the liquid flow tank and positions capable of being used for arrangement are fixedly connected with the thin-walled aluminum alloy casting through sprue gates; and the number of the liquid rise pipes and the number of the sprue gates are each at least two. The multi-furnace and multi-liquid-rise-pipe molten aluminum mold filling method structure is low in cost, convenient to install, stable and reliable, molten aluminum is injected into the liquid flow tank from the liquid rise pipes and cannot enter the thin-walled aluminum alloy casting through the sprue gates until the liquid flow tank is filled with the molten aluminum, in this way, it can be ensured that turbulent flow is controllable before the molten aluminum pouring, and therefore cold shut and gas inclusions are eradicated.

Description

technical field [0001] The invention relates to the technical field of metal materials or metallurgy, in particular to a sand mold low-pressure casting airtight thin-wall shell multi-furnace multi-liter pipe aluminum liquid filling method structure. Background technique [0002] Before the aluminum liquid rises in the traditional liquid riser aluminum liquid filling device and pours, there will be turbulent flow, cold shut and air pinch, which will seriously affect the later stage of liquid liquid pouring and affect the quality of the entire product. Contents of the invention [0003] The object of the present invention is to provide a method and structure of aluminum liquid filling with multiple furnaces and multiple riser tubes for sand mold low-pressure casting airtight thin-walled shell with simple and reasonable structure and low cost. [0004] The technical scheme adopted in the present invention is: [0005] A sand mold low-pressure casting airtight thin-wall shell...
