Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-ferrous metal die casting, and more particularly to a die casting device for non-ferrous metal production. BACKGROUND

[0002] Die casting, also known as pressure casting, is a forming process in which molten non-ferrous metal alloy is injected into a precision mold cavity under high speed and high pressure, and the desired casting is formed after cooling and solidification. Pressure casting is an indispensable key technology in the automotive, aerospace, electronic communication and daily hardware industries. Pressure casting has high productivity, is easy to mechanize and automate, and can produce complex thin-walled castings. Traditional die casting devices are usually composed of several core parts such as a pressure injection system, a mold closing system, a hydraulic system, a control system and a mold. The basic working principle is as follows: first, the mold closing mechanism locks two molds with cavities to form a sealed space; then, the pressure punch is driven by the hydraulic cylinder to push the molten metal liquid into the mold cavity at a very high speed; the metal liquid fills the cavity under great pressure and solidifies; finally, the mold is opened, and the molded casting is pushed out by the ejection mechanism. When pressure casting is performed, a mold release agent needs to be sprayed in the cavity to facilitate the final removal of the casting. However, when spraying the mold release agent, fixed or simple oscillating spray guns cannot accurately match the cavity profile of complex molds. When spraying, a large amount of mold release agent is sprayed to non-cavity areas, and complex structures may be insufficiently sprayed due to the shielding effect, leading to difficult demolding, sticking, and other defects. Flat areas are prone to liquid accumulation due to excessive spraying, resulting in quality problems such as cold shut, water lines or holes in the casting. Currently, the structure inside the cavity cannot be detected and the spraying mechanism cannot be automatically adjusted. When pressure casting is performed, the mold release agent forms fine oil mist particles when sprayed under high pressure and impacts the high-temperature mold surface. Long-term inhalation of oil mist containing multiple chemical substances may cause respiratory diseases. When demolding, the oil mist flies in different directions after the cavity is opened. Currently, different directions of oil mist cannot be adsorbed. SUMMARY
