Embodiment 1

[0010] The injection molding assembly process of the magneto rotor includes the following steps: a. stamping the flywheel housing; b. placing a guard ring in the flywheel housing; c. placing a magnetic tile above the guard ring in the flywheel housing; d. The flywheel housing of the tile is placed in the mold of the injection molding machine; e. inject colloid injection molding above the magnetic tile; f. take out the finished product from the injection molding machine for cooling. In the step e, the pressure during the injection molding process is set to 10-12MPa, the colloid temperature is set to 180-200°C, the mold temperature in the injection molding machine is set to 180-190°C, and the injection time is 100-130 seconds. In the step e, the mass range of the colloid for each injection is 30-50g.

Abstract

The invention belongs to the technical field of automatic assembling lines, and particularly relates to an injection-molding assembling process for a magneto rotor. The process includes the following steps of a, stamping a flywheel shell, b, placing a retaining ring in the flywheel shell, c, placing a magnetic shoe above the retaining ring in the flywheel shell, d, placing the flywheel shell provided with the retaining ring and the magnetic shoe in a mold of an injection molding machine, e, injecting rubber above the magnetic shoe for injection molding, and f, taking out a finished product from the injection molding machine and cooling the finished product. By means of the technical scheme, the retaining ring and the magnetic shoe can be placed in the flywheel shell according to a certain sequence, then the injection molding machine is used for direct injection molding after the rubber is injected, and manual brush coating and manual assembling are not needed.

Description

technical field [0001] The invention belongs to the technical field of magneto rotor assembly, and in particular relates to an injection molding assembly process of a magneto rotor. Background technique [0002] At present, the assembly of the motorcycle magneto rotor is mostly manual operation. The specific process is to first put the retaining ring inside the flywheel shell, brush the viscous glue evenly, and then evenly brush the viscous glue on the surface of the magnetic tile and put it into the flywheel shell. Finally, brush the viscous glue on the surface of the pole shoe and put it into the flywheel housing. After all the accessories are installed, press them tightly by crimping. The use of manual assembly will result in complicated procedures, low efficiency, high production costs, and the quality of manual gluing cannot be guaranteed. Contents of the invention [0003] The problem to be solved by the present invention is that manual assembly of the existing moto...
