Abstract

The invention provides a reusable memory mud core which is formed by special processing steps on the basis of the shape memory effect of memory alloy. The mud core structurally comprises a depoling rotating handle, a memory alloy spring, a locator and a cylindrical net material, wherein the depoling rotating handle is connected with the memory alloy spring, the memory alloy spring is twisted when the depoling rotating handle is rotated in the clockwise direction, and the surface area of the mud core is reduced to separate the memory mud core from a product. When the reusable memory mud core is in use, no harmful gas is generated, the ventilation property is good, and the requirements on mass and fast production are satisfied.

Description

technical field [0001] The reusable memory core of the present invention is applied to the field of aluminum alloy casting, especially the casting of the turbocharger compressor casing. Background technique [0002] Automobile turbochargers are energy-saving and emission-reducing products that improve the power performance of automobiles. The market demand is constantly growing, and the runners of aluminum alloy compressor casing products are made of disposable resin sand cores as models. The manufacture of the core consumes electricity, consumables, and labor, and harmful gases are generated during the production process. The indicators such as gas generation, exhaust performance, and cooling rate cannot meet the requirements of mass production. Contents of the invention [0003] The reusable memory core of the present invention utilizes the shape memory effect of the memory alloy and is manufactured through specific processing procedures. The structure of the core is c...
