Problems solved by technology

[0016] As described above, when there is a deviation in the distance from the decorative sheet 121 to the parting surface 127, when the decorative sheet 121 is pressed by a film clip (not shown) or when the mold is closed, the force acting on the decorative sheet 121 uneven
Therefore, the decorative sheet 121 may be broken and it is difficult to form continuously.
In addition, wrinkles or cracks in the pattern layer may occur due to cracks in the decorative sheet 121, resulting in poor appearance of the decorated resin molded product.
Also, even if the decorative sheet 121 is not broken when the

[0092] "Second Embodiment"

[0093] use Figure 5 A simultaneous molding and decorating apparatus according to a second embodiment of the present invention will be described. Figure 5 It is a perspective view which shows the state which attached the decorative sheet supply apparatus to the movable platen according to the second embodiment of the present invention. The simultaneous molding and decorating apparatus of the second embodiment is different from the simultaneous molding and decorating apparatus of the above-described first embodiment in that instead of fixing the fixing parts 5 and 15 to the frames 4 and 14 , the fixing parts 5 and 15 and the frame The turntables 6 and 16 are provided between 4 and 14 , and the frames 4 and 14 and the turntables 6 and 16 are fixed by fixing screws 7 and 17 which are an example of fixing means. The other points are the same, so the repeated description will be omitted below, and the differences will be mainly described.

[0096] "Third Embodiment"

[0097] A simultaneous molding and decorating apparatus according to a third embodiment of the present invention will be described with reference to FIG. 6 . 6 is a perspective view showing a state in which the decorative sheet supply device according to the third embodiment of the present invention is attached to the movable platen. The simultaneous forming and decorating apparatus of the third embodiment is different from the forming and decorating apparatus of the above-described first embodiment in that an insert sheet is used as the decorative sheet 21, and a clamping device 301 is provided instead of the decorative sheet winding device 11 and drive unit 302 . The other points are the same, so the repeated description will be omitted below, and the differences will be mainly described.

[0098] The interleaving sheet is different from the transfer sheet 101 in that it does not have the release layer 103 . That is, the insert sheet is a sheet ...

Abstract

Provided is a simultaneous molding-decorating apparatus, in which the axis of rotation of a decorative sheet let-off roll (2) of a decorative sheet feeding device (83) and the axis of rotation of a guide roller (3) are made parallel to a parking face (27) to have a decorative sheet (21) arranged thereon, so that the appearance defect of a resin molding due to the break and wrinkle of the decorative sheet (21) and the crack of a pattern layer may not be caused in the state where the parking face (27) is inclined with respect to a platen face (24a).

Description

technical field [0001] The present invention relates to a molding simultaneous decoration device suitable for decorating the surface of a resin molded product using a decorative sheet, a device installation jig, a mold, an injection molding machine, and a decorative sheet supply device included in the molding simultaneous decoration device, and A method of manufacturing a molded article while molding it. Background technique [0002] Conventionally, as a method of decorating the surface of a resin molded product, a molding simultaneous decoration method using a decorative sheet such as a transfer material is known. Here, the decorative sheet is obtained by providing a transfer layer having a release layer, a pattern layer, an adhesive layer, and the like on a base sheet. [0003] The molding simultaneous decoration method is a technique in which a decorative sheet is sandwiched into a mold while being arranged on a cavity of a mold, a molding resin is injected into the mold...
