[Previous technology] Rotary electric machines used as driving sources for electric two-wheeled vehicles and other general electric motors. In recent years, in addition to the radial gap rotary electric machines described above, steering gap rotary electric machines have also attracted much attention. As the steering gap type rotating electric machine, for example, the steering gap type electric motor has a disc-shaped rotor side yoke having a rotating shaft supported by its bearing, and a disc-shaped steel plate laminated on the center axis direction The structure of the body < fixer side vehicles facing each other, and the facing surfaces thereof are perpendicular to the rotation axis. Furthermore, a circular (or annular) boundary magnet (magnet) is arranged on the facing surface of the rotor-side vehicle, and the facing surface on the stator side is arranged along the radiation direction of the rotation axis (circumferential direction). ) Equipped with many τ-shaped pipe joints, the facing surfaces of the magnet and the T-shaped pipe joint are perpendicular to the rotation axis, and the gap between the facing surfaces forms a plane shape perpendicular to the rotation axis. In the steering gap type motor constructed as described above, the magnet of the rotor is often subjected to the load from the rotor side yoke in the peeling direction by the attraction force of the stator. For this reason, the attachment of the rotor-side yoke magnets must be performed more reliably and firmly. Here, as shown in FIG. 19, a large amount of an adhesive agent 151 is applied to the adhesion surface of the yoke 150, and the adhered surface of the magnet (magnet) 152 of the adherend is placed on the adhesive agent 151 'to face its magnet. On the surface to be attached, borrow a certain force

On the one hand, resin magnets (bonded magnets) having excellent workability and the like have recently been used as magnets for the steering gap type electric motors. This resin magnet can be obtained by injection molding a resin (mixture) of a mixed (composite) magnet powder and a binder resin. For example, FIG. 20 is a diagram showing an example of the injection molding apparatus 16. As shown in FIG. 20, if the injection molding device 16 is injected, the injection device ΐ6ι is used to inject the 'injection port 162' to transfer the mixture of the magnetic powder and the bonding resin (resin ·), the flow channel 163, and the gate 165 (toward the mold mold). Entrance in cavity 164) Fill and fill the inside of the ring-shaped mold cavity 164. After cooling and solidification is completed, the injection port and the flow path are cut off, and the mold 166 is opened to generate a ring-shaped resin magnet. When the injected and molded resin magnet is compared with, for example, a Greek soil magnet, the Greek soil magnet is liable to rust, and there is a concern that the magnetic characteristics are reduced when the rust occurs, and the motor output is reduced. In this case, when resin magnets are formed by injection molding, when the molten resin (mixture) flows into the mold during injection molding, the part connected to the low-temperature mold wall (the surface of the molded product) is called the skin layer. The temperature of the resin is reduced to form a hardened layer, so the occurrence of rust can be suppressed. However, in the above-mentioned adhesion between the vehicle and the magnet, since the adhesive is extruded firmly and firmly, it is necessary to use a strong load for the pressing process of the magnet, or after a long period of pressing process of the magnet, As a result, the energy necessary for rotor manufacturing is increased, and the manufacturing time is increased.
A\87338DOC 1228341 另外,藉強力負荷作推壓處理與經過長時間之推壓處 有可能會生成磁鐵的龜裂、切口、與輛的變形、對附 耆劑層的殘留應力等之虞慮。 特別是’使用上述之樹脂磁鐵的情形,藉成型收縮,如 圖21所顯示,樹脂磁鐵m的被附著面中央部i7i,由於由 其附著面朝向磁鐵17〇的正中央形成凹狀,所以與無凹狀部 分〈平面的情形相比’ & 了擠出附著劑,進一步必須有更 大之負荷力’製造時必須有更多的能源。另外,上述凹狀 部分m,由於容易㈣氣體(空氣)等,所以也有可能引 起殚鐵170的被附著面與輛172的附著面之黏接不良之虞 慮。 、 如此,在先前之磁鐵(樹脂磁鐵)與輛之黏接中,要求 改善能源的增大與製造時間的增加,加上起因於上述空氣 滯留之轉子製造之不良率的增大,與也有可能引起製品(使 用轉子之旋轉電機)的壽命降低之虞慮等。 進一步,在以射出成型生成樹脂磁鐵的情形中,如(參 照圖22(a)) ’圖22(b)所顯示,在生成之樹脂磁鐵(成型品) 180生成表皮層181。 此時,為了取出成型品180,在由成型品18〇切離注入口 162及流道163時,如圖22(b)所顯示,由於在其澆口部(流 道切離部分)165未生成表皮層181,所以成型品18〇的洗口 部165之磁粉剝下。從而,在成型品180中,為了防止鏽由 上述澆口部165發生,對於生成之成型品180,進一步有必 要施以防傭處理。A \ 87338DOC 1228341 In addition, there may be concerns about cracks in the magnet, notches, deformation of the vehicle, residual stress on the liniment layer, etc., caused by the strong load for the pressing process and after a long period of pressing. In particular, in the case of using the above-mentioned resin magnet, by molding shrinkage, as shown in FIG. 21, the center portion i7i of the adhered surface of the resin magnet m is concave from the attachment surface toward the center of the magnet 17o. Compared with the case where there is no concave portion (flat surface, compared with the 'extrusion adhesive', it must further have a larger load force ', and it must have more energy during manufacturing. In addition, since the concave portion m is liable to be exposed to gas (air), etc., there is a possibility of causing poor adhesion between the adhered surface of the plutonium iron 170 and the adhered surface of the car 172. In this way, in the past bonding of magnets (resin magnets) and vehicles, it was required to improve the increase in energy and manufacturing time, and the increase in the defective rate of rotor manufacturing caused by the above-mentioned air retention. This may cause a reduction in the life of the product (rotary electric machine using a rotor). Further, in the case where a resin magnet is formed by injection molding, as shown in (see FIG. 22 (a)) 'and FIG. 22 (b), a skin layer 181 is formed on the produced resin magnet (molded article) 180. At this time, in order to take out the molded product 180, when the injection port 162 and the runner 163 are cut off from the molded product 180, as shown in FIG. 22 (b), the gate portion (runner cutaway portion) 165 is not formed. Since the skin layer 181 is generated, the magnetic powder of the mouthwash portion 165 of the molded product 18 is peeled off. Therefore, in the molded product 180, in order to prevent rust from being generated by the gate portion 165, it is necessary to further perform an anti-filing treatment on the formed molded product 180.

As shown in FIG. 13, the injection molding device 100 includes an injection device 10, a mold 103, an injection port 104, a runner 105, and a gate 106; and the injection device 100 is used to bond magnet powder with The resin mixture (resin) is injected as a molding material; the mold 103 has a cavity (cavity) 1 0 2 corresponding to the shape of the object (resin magnet 91) to be manufactured (molded); the injection port! 〇4, the mixture C of the magnet powder and the bonding resin is transferred to the mold 103; the flow channel 105 is the resin material (mixture) c to be transferred through the injection port 104 and guided into the mold cavity 102 The gate 106 is the entrance when the runner 105 is filled with resin material into the cavity 102 of the mold. Furthermore, in the mold cavity 102 of the injection molding apparatus 100 of this embodiment, as shown in FIG. 13, the cavity surface 102a of the mold cavity surface 102a corresponding to the adhered surface 91a of the molded product (resin magnet) is applied. In the concave-convex treatment, the cavity surface i02a forms an uneven surface. Fig. 14 is a diagram of a resin magnet 91 generated (molded) by the injection molding apparatus 100 of Fig. 13. As shown in FIG. 14, an uneven surface is formed on the adhered surface 91a of the resin magnet 91 corresponding to the concave-convex surface of the cavity surface 102a, which can prevent the formation of a skin layer on the adhered surface 91a. In the following, the molding device 100 according to this embodiment is used to describe the manufacturing process of the resin magnet 91, and the effect of this embodiment will be explained. 0 A \ 87338 DOC -23-1228341 That is, when manufacturing the resin magnet 9, The mixture (resin) of the magnet powder and the bonding resin injected from the injection device 100 is transferred through the injection port, and the injection channel 105 is injected and filled into the cavity of the mold. At this time, the portion (the surface of the molded product) connected to the wall of the low-temperature mold 103 (the comparative temperature is small, so a skin layer is formed on the surface of the molded product (see FIG. 15). Here, the resin material 芫 is completely filled in the mold cavity 102, and after the injection is completed, the resin material in the mold cavity is gradually solidified. However, it is known that, before the curing of the injection molding resin material, by applying a holding pressure, a cut is generated between the molded product and the skin layer (see FIG. 16). Therefore, even in the configuration of this embodiment, the resin material injected and filled in the gate 10 is hardened by holding pressure, as shown in FIG. 17, between the resin material (molded product) C and the mold 103. There will also be clipping. At this time, according to this embodiment, since the cavity surface 102 corresponding to the adhered surface 91a of the molded product c (resin magnet 91) is a concave-convex surface, it is formed by cutting the molded product C on the substrate. The skin layer 11 of the adhesion surface 91a hangs on the skin surface and breaks. The adhered surface 9ia of the molded product C (resin magnet 91) corresponds to the unevenness of the skin surface 102a, and an uneven surface without the skin layer is formed (see FIG. 18). ). Then, by opening the mold 103, a ring-shaped resin magnet 91 of a molded product can be produced. Also, in this configuration, during injection molding, the surface 91a 'of the resin magnet 91 of the molded product c can be automatically embossed (concavo-convex processing) by the role of the cut surface 102a in response to the cutting. .

According to the above implementation, even if the rotor 9G of the resin magnet 91 produced by injection molding is used, there is no need to perform surface modification treatment. "Additional processing" During the injection molding process, the surface to be adhered ... is automatically subjected to uneven processing (embossing) to remove the skin layer, and the adhesion strength of the resin magnet 91 generated by the above injection molding can be improved. This resin magnet 9i is applicable to applications other than magnets for rotors.
