Manufacturing technology and device for shell of amorphous alloy watch

Abstract

The invention discloses a manufacturing technology and device for a shell of an amorphous alloy watch and belongs to the technical field of metal casting. The manufacturing device is composed of a raw material melting system, a mold system, a pressure casting system and a non-vacuum system. The non-vacuum amorphous alloy material machining device is designed through a vertical pressure casting technology. The raw material melting system is used for achieving the purpose of fast liquefying of amorphous alloy. The mold system is used for systematically achieving the purpose of fast solidification and one-time molding of the shell of the watch. The vertical pressure casting system is used for achieving the purpose that amorphous alloy liquid is rapidly and perpendicularly pressed into a mold cavity of the shell of the watch, and the problem that quality is affected due to bubbles generated in a casting is solved. The non-vacuum system is used for achieving the purpose of insulating air in the melting and pressure casting processes. The manufacturing device for the shell of the amorphous alloy watch is made of granular amorphous alloy raw materials containing zirconium, aluminum, copper, nickel and zinc, and the manufactured shell of the watch has the gloss of precious metal, namely platinum and is high in hardness and invariant in color. The device is suitable for being used as a universal device for manufacturing amorphous alloy products through one-time molding.

Description

1. Technical field [0001] The manufacturing technology and equipment of amorphous alloy watch case is a non-vacuum amorphous alloy material processing equipment designed with vertical die-casting technology, and its technology is in the field of metal casting. 2. Background technology [0002] Amorphous alloy refers to a metal alloy material in which the atoms inside the metal are arranged in a disordered state and there is no ordered lattice. It is also called liquid metal alloy or glass metal. Compared with ordinary metal alloy materials with metal crystals in which the atoms in the metal are arranged in an orderly manner, amorphous alloys have no fixed melting point and freezing point. Similar to glass and plastic materials, amorphous alloys are viscous in a certain temperature range, have good fluidity and filling properties, and are suitable for one-time molding by molds. Due to the high temperature of amorphous alloy melting and the chemical reaction between metal ato...
