The production process adopts an injection molding machine with a screw type as a mutation type, the rotational speed is 20-50 r / min; the temperature is 300-310 DEG C; the temperature of a charging barrel is 260-290 DEG C on the upper part, 280-290 DEG C on the middle part,and 260-280 DEG C on the rear part; the mold temperature is 90 DEG C; the injection pressure is 70-110 MPa; the holding pressure is 300-600 MPa; the total period is 10-20 seconds, and the injection time is 1-3 seconds; the pressure holding time is 1-5 seconds; the cooling time is 5-10 seconds; a drying device is in a hot air type; and the drying temperature is 120-140 DEG C, and the time is 4-6 hours. The production process can manufacture a motor carrier with a high precision screw thread.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a production process of a VCM motor component carrier. Background technique [0002] A VCM motor is a voice coil motor (Voice Coil Motor), which is a device that converts electrical energy into mechanical energy, and realizes linear and limited swing angle motion. A device that uses the interaction between the magnetic field from the permanent magnet steel and the magnetic poles in the magnetic field generated by the current-carrying coil conductor to produce regular motion [0003] At present, the voice coil motor mainly includes a casing, a base, a shrapnel, a carrier and a coil mounted on the carrier. The carrier is used to carry the lens, and the coil is wound on the carrier, so that after the coil is fed with electric energy, under the action of the magnetic field force of the magnet group, the two can simultaneously generate displacement along the axial directio...

Problems solved by technology

The carrier is used to carry the lens, and the coil is wound on the carrier, so that after the coil is fed with electric energy, under the action of the magnetic field force of the magnet group, the two can simultaneously generate displacement along the axial direction of the housing to realize the autofocus of the camera; but The existing motor carrier thread has low precision, which greatly reduces the precision of motor operation;
