Claims

1. A mold for avoiding magnetic attraction of carbon steel nut inserts in a rotor, characterized by, include: Front mold core, rear mold core, magnet assembly; The front mold core is installed on the top of the rear mold core, and an injection space is provided between the front mold core and the rear mold core; The bottom of the injection space is provided with several fixing holes, and a carbon steel nut insert is placed inside each fixing hole. Several of the said magnet assemblies pass through the bottom end of the rear mold core and are attracted to several of the said carbon steel nut inserts; The injection space contains stacked silicon steel sheets, and the stacked silicon steel sheets contain several magnets, with several carbon steel nut inserts corresponding to the spaced-apart magnets below them. The front mold core is provided with several gates, which are connected to the injection space. An external injection molding machine injects nylon plastic into the injection space through the gates to form nylon plastic. The nylon plastic covers several carbon steel nut inserts and stacked silicon steel sheets to form a rotor.

2. A mold for avoiding the magnetic attraction of a carbon steel nut insert in a rotor according to claim 1, characterized in that, Each of the aforementioned magnet components includes: a magnet pad, a spring, and a ferrite magnet; the magnet pad is mounted on the rear mold core, one end of the spring is mounted inside the magnet pad, the other end of the spring is mounted on the ferrite magnet, and the ferrite magnet is attracted to the carbon steel nut insert.

3. The mold for preventing the carbon steel nut insert in the rotor from being magnetically attracted, as described in claim 1, is characterized in that... Also includes: Front mold pin setting; One end of one of the aforementioned front mold inserts passes through the front mold core and extends into the injection space, thereby forming a plurality of upper support holes on the upper surface of the nylon plastic.

4. The mold for avoiding the carbon steel nut insert of the rotor being magnetically attracted according to claim 1, characterized in that, Also includes: Rear mold pin setting; One end of one of the rear mold inserts passes through the rear mold core and extends into the injection space, so that the lower surface of the nylon plastic forms a plurality of lower support holes.

5. The mold for avoiding the carbon steel nut insert of the rotor being magnetically attracted according to claim 1, wherein Also includes: Front mold insert; the front mold insert extends through the front mold core into the injection space so that the upper end of the nylon plastic forms an upper bearing mounting hole.

6. A mold for avoiding the magnetic attraction of a carbon steel nut insert in a rotor according to claim 1, characterized in that, Also includes: Rear mold insert; the rear mold insert extends through the rear mold core into the injection space so that the lower end of the nylon plastic forms a lower bearing mounting hole.

7. The mold of claim 1, wherein, The diameter of each gate gradually decreases towards the injection space.

8. The mold of claim 1, wherein, The front mold core is provided with several front mold cooling water holes.

9. The mold of claim 1, wherein, The rear mold core is provided with several rear mold cooling water holes.
