Amorphous alloy diecasting equipment and amorphous alloy diecasting process

Abstract

The invention discloses an amorphous alloy diecasting equipment and an amorphous alloy diecasting process. The amorphous alloy diecasting equipment comprises a fixed die, a movable die, a sealed bin, a protection-gas supplying device, a melting container, a pressing and ejecting cylinder, a driving device and a harmful-gas purifying device; the fixed die and the movable die can be opened and closed, and a die cavity is formed between the fixed die and the movable die in a defining way when the fixed die and the movable die are closed; a sealed chamber is formed in the sealed bin in a defining way, and the sealed bin is provided with a feeding opening; the protection-gas supplying device is connected with the sealed chamber and used for supplying a protection gas to the sealed chamber, wherein the protection gas in the sealed chamber is at positive pressure; the melting container is arranged in the sealed bin; the pressing and ejecting cylinder is communicated with the die cavity and provided with a melt inlet; the pressing and ejecting cylinder is internally provided with a pressing and ejecting piston used for ejecting the melted amorphous alloy into the die cavity; and the harmful-gas purifying device is connected with the sealed chamber and used for purifying the harmful gas in the sealed chamber. The amorphous alloy diecasting equipment disclosed by the embodiment of the invention has a simple structure, adopts the protective gas at positive pressure, does not need to establish a high vacuum degree and has low manufacturing and maintaining cost.

Description

technical field [0001] The invention relates to an amorphous alloy die-casting equipment and an amorphous alloy die-casting process. Background technique [0002] Amorphous alloy materials, also known as metallic glasses, have excellent physical and chemical properties, such as high yield strength, high hardness, and superelasticity, which are different from ordinary crystalline metal materials due to the unique arrangement structure of atoms that make up the alloy. (high elastic limit), high wear resistance, high corrosion resistance, etc. [0003] At the same time, amorphous alloys also have excellent casting properties due to their special structure and chemical properties. Due to the formation of an amorphous structure in the forming process of amorphous alloys, it is necessary to prevent the occurrence of heterogeneous nucleation. Since amorphous alloys usually contain active elements, such as zirconium, aluminum, magnesium, titanium, rare earth and other elements, it...

Problems solved by technology

However, the application of vacuum technology, especially the establishment of a high-vacuum environment, for example, in US Patent US6021840, the vacuum degree is even as high as 1000um Hg. In order to obtain a high vacuum degree, on the one hand, the equipment cost is increased, and on the other hand, the amorphous The casting cycle of the alloy reduces the production efficiency

At the same time, the vacuum system requires a complex closed system to maintain, which greatly affects the continuity and convenience of workers' operations and increases the difficulty of production
