Abstract

The invention discloses a squirrel cage motor rotor die casting device and method. The die casting device comprises a die casting machine and a melting furnace. The die casting machine is formed through the inserting and splicing combination of a movable die assembly, two replaceable die assemblies, a fixed die assembly and a pressure chamber die. The movable die assembly, the replaceable die assemblies and the fixed die assembly are sequentially arranged. The tail end of the pressure chamber die penetrates the fixed die assembly and makes contact with a closed cavity. A supporting frame is arranged below the movable die assembly. The defects of casting cracks, surface cracks, poor filling, die sticking and the like are avoided for products subjected to die casting, the vibration present value of the products meets the R-level regulation in IEC34-14(1996), and the level R is higher than the level N regulated by Y-series motor technique conditions by one level.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metal smelting and rolling processing, and in particular relates to a squirrel-cage motor rotor die-casting device and a die-casting method thereof. Background technique [0002] The cast copper rotor is a new type of motor rotor with copper as the conductive matrix. The conductivity of copper is about 40% higher than that of aluminum. The cast copper rotor is used to replace the cast aluminum rotor widely used in squirrel-cage three-phase asynchronous motors. The total loss of the motor will be able to drop significantly, improving the overall efficiency of the motor. Although cast copper rotors have many advantages, due to the difficulty of producing cast copper rotors, cast aluminum rotors are still widely used in electric motors. The difficulties in the production of cast copper rotors are: the purity of the copper melt and the high die-casting temperature. The casting temperature of cop...
