Embodiment approach 1
[0061] figure 1 and figure 2 It shows the decoration molding apparatus which implements the decoration molding method of this invention.
[0062] exist figure 1 In the drawing, the first mold 21 constituting the cavity of the molding die is shown by solid lines, and the second mold 22 is shown by phantom lines.
[0063] The strip-shaped film 7 supplied between the first die 21 and the second die 22 in the die-opened state passes from the unwinding part 1 between the first die 21 and the second die 22 to be stretched to the take-up part 3 . The distance between the first mold 21, the film 7, and the mold parting surface of the first mold 21 when the film 7 is supplied is provided with a gap of about 1 to 5 mm so as not to contact, but the present invention is not limited thereto.
[0064] A roll-shaped film package 4 is provided in the unwinding unit 1 . The film 7 of the film roll 4 is pressed against the delivery motor shaft 6 by the pinch roller 5 , and is pulled out ...
Embodiment approach 2
[0088] Figure 3 ~ Figure 5 Embodiment 2 is shown.
[0089] image 3 Only the structure of the mold-side alignment mark 16 and the film-side alignment mark 15 , and the peripheral portion of the camera 13 that simultaneously photographs them are shown, and other portions are the same as those in the first embodiment.
[0090] The lighting device 31 used for imaging by the camera 13 is arranged inside the first mold 21 . The parallel light 19 projected from the illuminating device 31 is emitted from the hole 28 opened on the parting surface of the first mold 21 . The mold-side alignment mark 16 is drawn on a transparent plate 20 such as glass arranged on the parting surface of the first mold 21 . The mold-side alignment mark 16 is colored in a transparent color, and is not limited to methods such as printing, engraving, or vapor deposition.
[0091] The film-side alignment mark 15 provided on the film 7 is transparent or translucent. In some cases, transparent films such a...
Embodiment approach 3
[0099] Figure 6 Embodiment 3 is shown.
[0100] In Embodiment 2, the lighting device 31 is arranged inside the first mold 21, but Figure 6 Among them, the lighting device 31 is disposed outside the first mold 21 . The parallel light 19 from the illuminating device 31 enters through the passage 33 formed in the first mold 21 , and the irradiation direction of the parallel light 19 is changed by the mirror assembly 32 to irradiate the mold side alignment mark 16 . The parallel light 19 reaches the camera 13 via the transparent plate 20 , the film 7 , and the mirror assembly 12 .
[0101] Generally, when resin is injection molded, the mold is molded under temperature control. Therefore, when the lighting device 31 is arranged in the mold as in Embodiment 2, the temperature of the lighting device 31 may exceed the allowable temperature range. For example 55°C. Therefore, in the third embodiment, the illuminating device 31 is arranged outside the mold, and if the mirror surfa...
