Abstract

The invention relates to a shaft packaging injection molding process for a motor rotor. The process comprises the following steps that firstly, a forming mold is manufactured; secondly, a rotating shaft, a rotor chip and end plate raw materials are placed into the forming mold; finally a finished motor rotor can be obtained through the one-off shaft packaging injection molding process on an injection molding machine, wherein pressure in the shaft packaging injection molding process is set to be 10MPa-12MPa, the temperature of the end plate raw materials is set to be 150 DEG C-165 DEG C, the temperature of the forming mold is set to be 175 DEG C-195 DEG C, and injection time is 145-155 seconds. Due to the fact that shaft packaging injection molding is completed at a time, manufacturing procedures are reduced, and cost is greatly reduced; and the forming mold of the process is provided.

Description

technical field [0001] The invention relates to an injection molding process of a motor rotor wrapped shaft and a molding mold thereof. Background technique [0002] The existing motor rotor wrapping forming process is as follows: 1. Wrap the shaft through the wrapping mold; 2. Process the outer diameter of the wrapped shaft to match the axis of the rotor chip; 3. Put the The shaft after machining the outer diameter is put into the rotor chip to obtain the semi-finished mandrel; 4. Stamp the insulating end plate through the end plate die; 5. Press the insulating end plate on both ends of the semi-finished mandrel to obtain the finished product. [0003] There are many procedures in this process, and the cost of personnel and materials required is relatively large, time-consuming and labor-intensive, and the average material cost of each product reaches 2.6 yuan. Contents of the invention [0004] The purpose of the present invention is to provide a shaft-wrapped injection...
