Description

technical field

[0001] The invention relates to a temperature control system and method in the die-casting production process, in particular to a multi-point precise temperature control system and method for a die-casting mold. Background technique

[0002] At present, die casting is a special casting method with less cutting and no cutting that develops rapidly in modern metal processing technology. It is a process in which molten metal is filled into a mold under high pressure and high speed, and crystallized and solidified under high pressure to form a casting. High pressure and high speed are the main characteristics of die casting. The commonly used pressure is tens of MPa, the filling speed (ingate speed) is about 16-80 m / s, and the time for the molten metal to fill the mold cavity is extremely short, about 0.01- 0.2 seconds. Since casting castings by this method has the advantages of high production efficiency, simple process, high tolerance level of castings, good s...
