Description

Auxiliary device for casting aluminum lithium alloy

Technical Field

The utility model belongs to the field of aluminum lithium alloy production equipment, and particularly relates to an auxiliary device for aluminum lithium alloy casting.

Background

The aluminum-lithium alloy is widely applied to important fields of aerospace, transportation and the like due to the characteristics of small specific gravity, good processability, excellent corrosion resistance and the like. In the preparation process of the aluminum-lithium alloy, casting is an important process in the production of the aluminum-lithium alloy, and the quality of cast ingots determines the final performance of the aluminum-lithium alloy product.

When aluminum lithium alloy ingots are prepared in small-batch flexible production or laboratory conditions, a water-cooling copper mold is generally adopted for casting. During casting, a water-cooled copper mold should be placed on the dry metal plate to prevent the aluminum liquid from splashing due to the evaporation of the bottom surface water. When casting is started, the copper mold needs to be placed obliquely, and aluminum liquid flows down along one side wall of the copper mold, so that the defects of air holes, looseness and the like of cast ingots caused by gas entrainment are avoided. After the bottom of the water-cooling copper mold is fully paved with the aluminum liquid, the water-cooling copper mold is slowly leveled at a constant speed while the aluminum liquid flows into the copper mold until the copper mold is fully poured. However, the water-cooled copper mold for casting the aluminum-lithium alloy is heavy, and the aluminum-lithium alloy is slowly laid down by tilting and is laborious to cast; meanwhile, liquid drops inevitably splash when the molten aluminum flows into the copper mold in the casting process, and potential safety hazards exist.

Patent CN214640243U discloses a mold auxiliary device capable of tilting casting, comprising a support, on which a mold clamping assembly is arranged; the support is provided with a driving component, and the mould auxiliary device capable of being obliquely cast is driven by a stepping motor. However, the auxiliary device of the patent cannot be used in combination with a water-cooled copper mold, and the operation of replacing the mold is complicated and is a great disadvantage.
