An amorphous alloy die-casting process

Abstract

The invention discloses an amorphous alloy die-casting process. In the process, die-casting equipment is used to complete the die-casting process of the amorphous alloy. The equipment includes an installation base, a support frame, a rotating disk, a feeding box, a die-casting cylinder, an installation column, an installation Bottom plate, installation top plate, feeding cylinder, support sleeve, pressure plate, conveying material pipe, forming groove, mold, sliding sleeve, guide rod, mounting plate, sealing cover, spring column, forming column, support plate, drive motor, through The feeding box heats the amorphous alloy to melt and store it. The molten alloy enters the mold through the operation of the feeding cylinder, and the molten alloy in the mold is hydraulically formed through the operation of the die-casting cylinder. The equipment is simple in structure and easy to use. The drive motor drives the rotary disc to rotate, thereby driving several forming grooves and molds to rotate, so that multiple molds can continuously produce products, with high work efficiency and fast product production speed, which is suitable for rapid production of small and medium-sized parts.

Description

technical field [0001] The invention relates to the technical field of alloy die-casting, in particular to an amorphous alloy die-casting process. Background technique [0002] Amorphous alloy is a new type of amorphous metal glass material which is synthesized by modern rapid solidification metallurgy technology and has excellent mechanical, physical and chemical properties of general metal and glass. This material is smelted from metal raw materials, and its appearance is as shiny as ordinary metals, and there is no difference on the surface. Amorphous alloy is called metallic glass, but not because it is brittle and transparent like glass, but because the internal atomic arrangement of this metal is long-range disordered like glass, which is a glassy structure. Under normal circumstances, metal alloys such as steel, copper alloys, aluminum alloys, etc. that we often see will crystallize during the cooling process, and the atoms inside the material will be arranged in an ...

Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide an amorphous alloy die-casting process: by adding the amorphous alloy into the inner cavity of the feeding box, closing the reversing door and starting the heating wire, the amorphous alloy The alloy is melted to obtain the alloy melt. According to the requirements of the production shape, the mold is installed in the forming tank, the drive motor is started, and the driving motor runs to drive the rotating disk to rotate, so that one of the forming tanks is located directly below the conveying material pipe, and makes The conveying pipe is in contact with the mold, and the feeding cylinder is started. The movable rod of the feeding cylinder is extended to push the pressing plate down. During the descending process of the pressing plate, the molten alloy is poured into the conveying pipe and into the mold, driven by the driving motor. The rotating disk rotates to move the next forming tank directly below the delivery pipe, and at the same time moves the mold injected with the alloy melt to the bottom of the sealing cover. The mold to be injected with the alloy melt is located directly below the seal cover. The movable rod of the cylinder extends through the guide rod to make the mounting plate move downwards, thereby driving the sealing cover to cover the forming groove, the spring column shrinks and the forming column continues to descend, and the forming column enters the mold to press the alloy melt in the mold. After the formed amorphous alloy is cooled and shaped, the target product is obtained, and the die-casting process of the amorphous alloy is completed, which solves the problems that the existing amorphous alloy die-casting technology is still not mature enough, the cost of preparing parts is high, and the efficiency is low
