Description

Technical Field

[0001] The utility model relates to the technical field of quality inspection devices, in particular to a die-casting part of a display bracket. Background Art

[0002] The mold is an important process equipment for forming. The die casting process is a process that uses three major elements, namely, machines, molds and alloys, to unify pressure, speed and time. For metal hot processing, the existence of pressure is the main feature of the die casting process that distinguishes it from other casting methods. Die casting is a special casting method with little cutting that has developed rapidly in modern metal processing technology. It is a process in which molten metal is filled into the mold under high pressure and high speed, and crystallized and solidified under high pressure to form a casting.
