Technical Field

[0001] The utility model belongs to the technical field of motor rotor manufacturing, and in particular relates to a die-casting device for a motor rotor. Background Art

[0002] As the core rotating component of the motor, the motor rotor cooperates with the stator to convert electrical energy into mechanical energy, which is the basis for the realization of the motor function. At present, for the precision manufacturing of motor rotors, dedicated die-casting equipment is generally adopted for efficient production;

[0003] After the rotor is formed, the existing die-casting technology generally uses a cylinder to drive the ejector to perform the ejection operation. Although it can meet the basic demolding requirements, there are still some problems in daily operation. Specifically, after the ejection process is completed, dust particles are often left in the mold cavity. These dust particles will be embedded in the new rotor in the subsequent die-casting process, causing surface defects or internal structural defects, thereby affecting the performance and consistency of the product.
