Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an injection-molded article with a skin, which includes a skin and a resin base integrally injection-molded on the inner surface of the skin.

(Prior Art) The injection-molded article with the skin is widely used for automobile interior parts such as a pillar garnish or a console lid.

Conventionally, in order to improve the appearance of the end of the molded product and prevent the peeling of the skin, the injection-molded product with the skin is wound up with the end 12 of the resin base 10 as shown in FIG.
Is folded back to the back side of the resin base 10 and the skin terminal 16 is fixed to the back surface of the base terminal 12 with a tucker or an adhesive.

(Problems to be solved by the invention) However, in the injection-molded article with the skin having the above-mentioned structure, peeling of the skin terminal is often caused by variations in adhesiveness of the adhesive. Further, since the skin is usually made of a material that is soft and easily deformed, and it is difficult to cleanly fold the end of the skin cleanly, wrinkles are likely to occur at the folded portion, and the appearance of the molded product deteriorates. Furthermore, since adhesives, tackers, and other auxiliary materials are required, there is a problem that the product price rises.

Therefore, this invention intends to provide an injection-molded product with a skin, which prevents peeling of the skin end, prevents wrinkles of the skin on the end of the molded product, and further eliminates the need for auxiliary materials. .

(Means for Solving the Problems) The gist of the present invention for achieving the above-mentioned object is to provide an injection-molded article with a skin, which comprises a skin and a resin base integrally injection-molded on the inner surface of the skin. A main body having a bar-shaped projection on the back surface and a flange portion having a small hole provided in the main body terminal via a groove-shaped hinge portion, and a skin terminal corresponding to the small hole of the flange portion. The resin base body has a flange portion and the skin end of the surface of the flange portion bent to the back side of the base body by a hinge portion, and the small hole of the flange portion and the skin end has a rod shape on the back side of the main body. An injection-molded article with a skin, characterized in that the tip of the projection is inserted and the tip of the rod-shaped projection is formed in an enlarged shape on the surface end of the skin.

(Operation) Since the skin end is bent together with the flange portion and the flange portion is made of a resin base having higher rigidity than the skin, wrinkles are less likely to be formed on the skin near the bent portion.

Furthermore, the skin terminal and the flange portion are bent by the groove-shaped hinge portion, and since uneven force is not applied to the skin terminal and the flange portion at the time of the bending, the skin near the bent portion is further wrinkled. It gets harder.

Further, since the end of the bar-shaped projection that is inserted into the small hole of the skin end and the flange part that is bent on the back side of the resin base body is enlarged on the surface of the skin-side end, the skin-end part is disengaged from the end of the bar-shaped protrusion and the flange part is removed. It does not come off.

(Embodiment) An embodiment of the present invention will be described below.

1 to 3 are views showing an injection-molded product with a skin according to an embodiment of the present invention, in which FIG. 1 is a sectional view of the injection-molded product with a skin, and FIGS. 2 and 3 are skin terminals. FIG. 3 is a cross-sectional view and a perspective view showing a flange portion before being bent.

The injection-molded article 20 with the skin is used as a pillar garnish in an automobile, and includes the skin 22 and the skin 22.
Consisting of a resin base 24 integrally injection-molded on the inner surface,
After the injection molding, the skin end 26 and the flange portion 25 of the resin base body 24 are bent to the back side of the resin base body 24 and fixed to the tip 29 of the rod-shaped projection 27 on the back side.

First, the skin 22 and the resin base 24 in the state before the bending shown in FIGS. 2 and 3 will be described.

The skin 22 is made of synthetic resin, fabric, or the like, and a plurality of small holes 28 are formed in the side skin terminals 26, 26 at predetermined intervals. In addition, the small hole 28 of the skin end is formed so that it overlaps with the small hole of the flange portion 25 described later.
It is provided corresponding to the position of 25 small holes.

The resin base 24 is made of a synthetic resin such as vinyl chloride resin or ABS resin, and has a main body 30 and a flange portion 25 provided on a side portion of the main body 30 via groove-shaped hinge portions 32, 32. , 25, and the flange portions 25, 25 are injection-molded on the inner surface of the skin 22 with the flange portions 25, 25 extending outward.
A plurality of rod-shaped projections 27 are formed on the main body 30 at predetermined positions on the back side, and a plurality of small holes 34 are formed in the flange portions 25, 25. The small hole 34 of the flange portion 25 is formed at a position where it overlaps with the small hole 28 of the skin terminal 26 as described above, and the rod-shaped projection 27 has the flange portion 25 and the skin terminal 26 at the hinge portion.
It is formed at such a position that the tip 29 of the bar-shaped protrusion 27 fits into the small holes 28 and 34 of the skin end and the flange when bent at 32 and 32. The injection molding of the resin base 24 is
This is done by mounting the skin 22 on the cavity surface of an injection mold (not shown) and injecting resin into the remaining cavity.

Next, the injection-molded product 20 with a skin, which is the final product shown in FIG. 1, will be described. The skin-molded injection-molded article 20 has a structure in which the skin 22 and the resin base 24 integrally formed by injection are such that the skin terminal 26 and the flange 25 are the hinge parts of the resin base 24.
It is bent to the back side of the resin base body 24 by 32, the tip 29 of the bar-shaped projection 27 is inserted into the small holes 28, 34 of the skin end 26 and the flange portion 25, and the bar-shaped projection tip 29 is deformed by heating, as shown in FIG. 29a, the outer skin 26 and the flange portion 25 are fixed to the tip 29 of the rod-shaped projection in an enlarged shape like 29a.

The enlarged shape portion 29a of the tip 29 of the rod-shaped projection is formed on the skin terminal 26
Also, the tip 29 of the rod-shaped projection is sized so as not to come off from the small holes 28, 34 of the flange 25.

In the above description, the present invention has been described by taking the pillar garnish as an example, but the present invention is not limited to this, and is also applied to a console lid or other injection-molded article with a skin. Further, depending on the use and shape of the molded product, a hinge portion, a flange portion, etc. may be provided only on one end of the resin main body, and only the skin end and flange portion on one side may be bent.

(Effect) Since the present invention has the above-mentioned structure, it is possible to prevent wrinkles from being generated on the skin end covering the end portion of the molded product, and to prevent the skin end from peeling off. It was possible to obtain an injection molded product.

In addition, it is possible to eliminate the troublesome tacker stop or adhesive application work that has conventionally been done to prevent peeling of the skin terminal, resulting in easier manufacturing work and using separate parts to prevent peeling. There is also the effect that the product will be cheaper because it is not.
