Embodiment 1
A method for manufacturing the magnetic therapy device of the present embodiment will be described with reference to FIGS.

  First, in step (a), a thermosetting resin material is injected into the cavity C of the female mold 4 by an injection device or manually. As the thermosetting resin material, thermosetting silicone is preferably employed. Next, in step (b), the male mold 5 is fitted into the female mold 4, and then the molds (4, 5) are closed, followed by pressurizing and heating at a predetermined pressure and temperature of about 180 ° C. for about 10 minutes. To mold. In step (b), when a long molded body (a molded body having a U-shaped cross section) 2a provided with a groove G is obtained by the protrusion P of the male mold 5, only the male mold 5 is obtained in the process (c). The mold (4, 5) is opened, and the molded body 2a of the thermosetting resin material is retained in the female mold 4 to form a long molded body 2a having a U-shaped cross section. A mixture of magnetic powder and silicone oil is poured into the groove G. At this time, when left for an appropriate time in the groove G, the magnetic powder having a large specific gravity settles downward, and as shown in FIG. 5, the layer 3a mainly composed of the magnetic powder and the layer mainly composed of the magnetic powder. A silicone oil layer 3b on 3a is formed. Also in this step (c), the molded body 2a, the layer 3a mainly composed of magnetic powder, and the silicone oil layer 3b on the layer 3a mainly composed of the magnetic powder are formed on the female mold 4 without releasing from the female mold 4. Keep it. Then, in step (d), it is loaded into an electric furnace and heated at a temperature of about 120 ° C. for 10 minutes. Then, the silicone oil layer 3b in FIG. 5 is cured to obtain the silicone layer 3c. That is, as shown in FIG. 6, in a groove G (see FIG. 4) provided in the longitudinal direction of the long body 2a, a layer 3a mainly composed of magnetic powder and a layer 3a mainly composed of the magnetic powder. And a cured silicone layer 3c.

  Next, referring to FIG. 6, in the present embodiment, ribs 2b are provided in the openings of the layer 3a mainly composed of magnetic powder. As described above, in the step (c), the mold (4, 5) is opened, and the mixture of magnetic powder and silicone oil is placed in the groove G formed in the long molded body 2a having a U-shaped cross section. This is because the upper surface and side surfaces of the silicone layer 3c after being injected and cured are made uniform.

  FIG. 7 shows a form in which the magnetic therapy device 1 of the present embodiment is connected in a ring shape.

  In this embodiment, the female portion 7f is made of silicone resin and the shaft 10 of the male portion 7m is made of polyacetal. However, the present invention is not limited to this, and the female portion 7f is made of a soft elastomer and the shaft 10 of the male portion 7m is made. Can be a hard elastomer such as polyamide or polycarbonate.

  The male portion 7m protrudes from the end surface of the male portion 8 and has a substantially hemispherical engagement portion having a diameter larger than the diameter of the cross section of the shaft 10 at the tip of the shaft 10 formed of a hard elastomer (for example, polyacetal). 11 is formed, and the engaging portion 11 is inserted into the recess 9 of the female portion 7f.

  Referring to FIG. 7, a plurality of silicone oil layers 3b on a layer 3a mainly composed of magnetic powder are intermittently provided on a long elongated body 2a (that is, a layer 3a mainly composed of magnetic powder and And a plurality of grooves G (see FIG. 4) filled with the silicone oil layer 3b). This is to make the amount of the mixture of magnetic powder and silicone oil injected into the groove G evenly. If the cost is not considered, the groove G is formed over the entire length of the long molded body 2a. It is also possible to inject a mixture of magnetic powder and silicone oil. In addition, it is preferable that the mixture ratio of magnetic powder and silicone oil is 7: 3-9: 1. This is because the strength of magnetization can be increased.

  Further, the ratio of the depth to the width of the groove G is preferably 1: 1.5 to 1: 3.5. This is because the amount of magnetic powder injected can be increased by increasing the depth of the groove G, whereby the strength of magnetization can be increased.
