Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
Example 1
As shown in fig. 6-11, the injection molding motor stator comprises an injection molding motor stator body 1 and a motor outgoing line 4, wherein a wire harness outgoing line 3 is arranged on the injection molding motor stator body 1, an injection molding boss 2 is arranged at the wire harness outgoing line 3, an upper wire pressing block 5 and a lower wire pressing block 6 are arranged on the motor outgoing line 4, a wire slot 8 for the penetration of the motor outgoing line 4 is arranged between the upper wire pressing block 5 and the lower wire pressing block 6, an injection molding step 7 is formed at the root of the motor outgoing line 4 after the upper wire pressing block 5 and the lower wire pressing block 6 are pressed along the injection molding boss 2, and a groove 9 corresponding to the injection molding step 7 is arranged in the wire slot 8. The groove 9 is a truncated cone-shaped groove.
The injection molding step formed by the utility model reduces the damage probability of the root of the outgoing line during injection molding and die assembly, and improves the reliability of injection molded stator products. The injection molding step formed simultaneously reduces root fracture caused by bending deformation of the motor outgoing line in the using process of the injection molding motor.
As shown in fig. 12, when the injection mold is assembled up and down, the upper pressing line block 5 and the lower pressing line block 6 form a small injection molding step 7 at the root of the motor outgoing line 4 after being pressed along the injection molding convex plate 2, the injection molding step 7 is tightly attached to the injection molding boss 2, the contact surface area of the injection molding step 7 and the injection molding boss 2 is S2, and the area far away from the injection molding boss 2 is S1, wherein S2 is larger than S1.
As shown in fig. 13, the injection molding step 7 is provided with a through hole for the outgoing line 4 of the motor to go out. According to the utility model, the motor outgoing line 4 passes through the injection molding step 7, so that the root of the motor outgoing line 4 is protected. The motor outgoing line 4 is isolated from the edge of the wire harness outgoing line 3, so that the motor outgoing line 4 is prevented from being cut and damaged; and when the motor outgoing line 4 is bent, the injection molding step 7 deforms under the action of elasticity, so that the motor outgoing line 4 is protected from being damaged, S2 is larger, and meanwhile, the motor outgoing line 4 can be combined with the injection molding boss 2 more tightly, so that the damage of the injection molding step 7 is prevented, and the motor outgoing line 4 is better protected.
The injection molding cost of the injection molding step is increased when the injection molding step is too large, and the injection molding step is too small, so that a good protection effect can not be provided for the motor outgoing line, and therefore, the thickness of the injection molding step 7 is 1/2 to 2/3 of the diameter of the motor outgoing line 4. More preferably, the thickness of the injection molding step 7 is 7/12 of the diameter of the motor outgoing line 4. The inclination angle of the injection molding step 7 is 45 degrees to 60 degrees. More preferably, the inclination angle of the injection molding step 7 is 52.5 degrees.
Example 2
The utility model also provides a motor comprising a rotor and the injection molded motor stator of embodiment 1.
While the utility model has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
