[0030]
Hereinafter, a method for manufacturing the above-mentioned switch-embedded resin molded product 1 will be described with reference to FIGS.
First, as a molding process, an integrally molded product in which the switch base 4 and the base material 3 are integrally combined is formed by insert molding. That is, in this molding, the switch base 4 is disposed in the cavity 60 formed by the pair of molding dies 6. At this time, the skin material 5 and the switch base 4 are sandwiched between the pair of molds 6, and the surface 401 of the main body portion 42 of the switch base 4 forms one mold 61 in the pair of molds 6. Abut without gaps. And the surface 411 of the switch press part 41 in the said switch base 4 forms the state which is not exposed to the said cavity 60. FIG.
[0031]
Then, the synthetic resin 30 for the base material 3 is injected into the cavity 60. At this time, since the surface 401 of the main body portion 42 of the switch base 4 is in contact with the one mold 61 without a gap, the synthetic resin 30 does not flow into the surface 411 of the switch pressing portion 41. Then, the synthetic resin 30 flows so as to cover the side surface 403 of the main body portion 42 which is a portion exposed to the cavity 60 of the switch base 4 and is filled in the cavity 60.
[0032]
Thereafter, the synthetic resin 30 is solidified to form the base material 3, and the base material 3 and the switch base 4 are integrated. In this way, the switch base 4 is integrally incorporated in the base 3, and the position of the surface 411 of the switch pressing portion 41, the position of the surface 401 of the main body 42, and the base 3 The integrally molded product 2 in which each of the positions of the surface 301 is substantially flush is formed (see FIG. 4).

[0033]
The sensing part 45 can be incorporated in the switch base 4 in advance, and the switch base 4 incorporating the sensing part 45 can be arranged in the molding die 6 to mold the integral molded product 2.
[0034]
The switch-embedded resin molded product 1 of this example is obtained by integrally combining the base material 3 and the switch base 4 which is a separate part from the base material 3 by insert molding. The position of the surface 411 of the switch pressing part 41 and the position of the surface 401 of the main body part 42 are substantially flush with the position of the surface 301 of the substrate 3. Further, these substantially flush surfaces 411, 401, 301 are covered with the soft skin material 5.
[0035]
Therefore, irregularities due to the surfaces 411, 401, and 301 are not formed on the surface 501 of the skin material 5. Therefore, the resin molded product 1 with a built-in switch can exhibit an appearance with an excellent sense of unity as if there is no boundary. Therefore, according to this example, it is possible to obtain the resin molded product 1 with a built-in switch excellent in the sense of unity between the switch and the resin molded product.
[0036]
( Reference example )
The switch built-in resin molded product 1 in this example is formed by integrating the switch base 4, the base material 3, and the skin material 5 by insert molding. That is, in this example, not only the switch base 4 is disposed in a pair of molds 6 but also the skin material 5 is disposed to perform insert molding.
Others are the same as in the first embodiment.
[0037]
Below, the manufacturing method of the resin molded product 1 with a built-in switch of this example is demonstrated using FIG.
In this example, first, the skin material 5 is disposed in one mold 61 of the pair of molds 6, and the switch base 4 is disposed in the other mold 62. At this time, the skin material 5 and the switch base 4 are sandwiched between the pair of molds 6, and the surface 401 of the main body portion 42 of the switch base 4 abuts against the back surface 502 of the skin material 5 without a gap. And the surface 411 of the switch press part 41 in the said switch base 4 forms the state which is not exposed to the said cavity 60. FIG.
[0038]
Then, the synthetic resin 30 for the base material 3 is injected into the cavity 60 formed by the pair of molds 6. At this time, since the front surface 401 of the main body portion 42 is in contact with the rear surface 502 of the skin material 5 without a gap, the synthetic resin 30 does not flow into the front surface 411 of the switch pressing portion 41. Then, the synthetic resin 30 flows so as to cover the side surface 403 of the main body portion 42 which is a portion exposed to the cavity 60 of the switch base 4 and is filled in the cavity 60.
[0039]
Thereafter, the synthetic resin 30 is solidified to form the base material 3, and the base material 3, the switch base 4, and the skin material 5 are integrated. The switch base 4 is integrally incorporated in the base 3, the position of the surface 411 of the switch pressing portion 41, the position of the surface 401 of the main body 42, and the position of the surface 301 of the base 3.
