The invention provides an electromagnetic driving vacuum die-casting machine. The electromagnetic driving vacuum die-casting machine comprises a driving assembly, a fixed die assembly, a movable die assembly and an executing assembly; a rear cover and a heat insulation plate are respectively positioned at the two ends of a cylindrical shell; a stator ferromagnetic ring is positioned inside the cylindrical shell; a rotor sleeve is positioned inside the stator ferromagnetic ring; a stator winding is connected with an iron core of the stator ferromagnetic ring; stator magnetic isolation rings areuniformly distributed on the inner surface of the cylindrical shell; rotor fan-shaped salient poles are uniformly distributed on the rotor sleeve; a fixed die plate is connected with a fixed die; thefixed die is connected with a movable die; the movable die is connected with a movable die plate; a pressure chamber is positioned inside a rectangular shell, the fixed die plate and the fixed die; amolten metal pouring gate is positioned at the upper part of the second end of the pressure chamber; the first end of the pressure chamber is connected with an inflow hole of a transverse pouring channel; the first end of an injection rod is connected with the rotor sleeve; the second end of the injection rod is connected with an injection plunger; and the injection plunger is positioned at the second end of the pressure chamber. According to the electromagnetic driving vacuum die-casting machine, the starting time can be shortened through the electromagnetic driving, the speed required by injection can be reached in a very short time, the eddy current loss is small, and the electromagnetic driving vacuum die-casting machine has the characteristics of large average injection force.

Description

technical field [0001] The invention relates to the technical field of forming precision parts, in particular to an electromagnetically driven vacuum die-casting machine. Background technique [0002] At present, with the continuous deepening of research on amorphous alloys, numerous research results have been formed. As a new type of material with very high strength, hardness and corrosion resistance, amorphous alloy has obvious advantages in impact fracture performance. Its elastic modulus is very low but it can store a large amount of elastic energy, and its energy transfer performance is also very good. Amorphous alloys are widely used in the fields of precision mechanical instrument parts, electronic devices, aerospace devices and sports equipment. Although amorphous alloys show obvious advantages in all aspects, they have obvious glass transition, very high supercooled liquid stability and decrystallization thermal stability, and bulk amorphous alloys are extremely st...
