けられる。 As shown in FIGS. 1 and 2, the resin decorative molding 10 according to the present invention has a longitudinal shape in the front-rear direction of a body (not shown), and has a synthetic resin molding base and a molding base provided on the surface of the molding base. It consists of a bright shining part 11. A double-sided adhesive tape (not shown) is attached to the back surface of the molding base, and the molding 10 is attached to the body via this double-sided adhesive tape.

る（第４図、第５図参照）。 The degree of foaming of the molding base 13 that substantially forms the back surface of the molding base body is adjusted as appropriate in the longitudinal direction of the molding 10, and its thickness, ie, the shape of the back surface, is set. As shown in FIG. 3, the molding 10 has a substantially constant wall thickness from the left side in the figure to the longitudinal center portion, and the wall thickness gradually changes to a thinner thickness in the range L from the center portion to the right side of the molding 10. (See Figures 4 and 5).

きる。 In this way, since the back surface of the molding base is made partially thin, the molding 10 can be removed from the general part of the body.
Even if it is installed over the fender part that protrudes outward compared to the general part of the body, the protruding part is absorbed by the thin part of the molding base, so the outermost portion of the molding 10 in the installed state is The position is made substantially uniform at any position of the molding 10. Thereby, it is possible to prevent the vehicle width regulation value from being exceeded due to attachment of the molding 10 at the fender portion that protrudes outward from the general portion of the body.
次に、樹脂製装飾モール１０の製造方法につい
て説明する。 Next, a method for manufacturing the resin decorative molding 10 will be explained.
第１０図に図示したように、まず、光輝部１１

る。 As shown in FIG. 10, first, the bright part 11
Continuous stainless steel foil or plate 11
A is formed into a predetermined shape using a roll forming machine 16.
Further, using an extrusion molding machine 17, the foamable resin for the molding base and the resin for the molding skin part 12 are integrally molded onto the stainless steel plate 11a for the bright part to have a uniform cross section in the longitudinal direction, thereby forming a molding base material 10a. During this extrusion molding, the stainless steel plate 11a is fixed to the foamable resin for the molding base with an adhesive (not shown).

ないようにさせられる。 The foamable resin for the molding base 13 is foamed to some extent during extrusion molding, and is in a so-called incompletely foamed state. In addition, the resin that becomes the molding skin part 12 is the bright part 1 that is adhered onto the foamable resin for the molding base 13.
1 and covers both longitudinal edges of the molding base 13.
It is fused to both sides of the foamable resin in the longitudinal direction. As a result, both edges of the bright part 11 are covered to prevent peeling, and the foamed shape of the molding base 13 made of foamable resin is prevented from being exposed on the surface of the molding 10.
次に、冷却機１８により、モール母材１０ａを
冷却すると共に、更に、切断機１９でモール母材

うにさせられている。 As shown in FIG. 11, the high-frequency heating molding machine 20 includes upper and lower molds 24 and 25 of push-in type made of silicon with a low dielectric loss factor, a high-frequency oscillation device 21, and a high-frequency wave from the high-frequency oscillation device 21. a pair of electrodes 22 for applying a voltage into the molds 24, 25;
23. In the molds 24 and 25, mold surfaces are formed in a predetermined shape. The lower mold 24 has a mold surface corresponding to the surface of the molding 10, and the upper mold 2
5 has a mold surface corresponding to the back surface of the molding 10,
The molding 10 is made to have an irregular cross-sectional shape in the longitudinal direction.

る。 Inside the molds 24 and 25, the molding piece 10b is placed with its surface facing down, and resin 14 for the molding ends 14 and 15 prepared separately in advance is placed on both sides of the molding piece 10b.
a and 15a are respectively arranged. After that, a high frequency voltage is applied. As a result, the foamable resin with a high dielectric loss factor forming the molding base 13 is heated and re-foamed. Due to the re-foaming, the molding base 13 expands according to the shape of the molds 24 and 25, and the molds 24 and 25 are filled. Alternatively, it becomes a predetermined shape by compression.

れることとなる。 In addition, the resin pieces 14a and 15a for the molding ends 14 and 15, which have a high dielectric loss factor, are also melted, and the molding piece 10b
Molding end portions 14 and 15 are formed by being fused to the molding base portion 13 and the molding skin portion 12 so as to cover the bright portion 11 of the cut portions at both ends. As a result, the molding 10 is molded into an irregular shape in the longitudinal direction of the molding according to the shape of the mold surfaces of the molds 24 and 25.

形に成形できる。 During high-frequency heating molding of the molding 10, the bright portion 11 is held by the molding base 13 in a semi-foamed state. Moreover, the surface portion of the molding 10 having the bright portion 11 is not specially molded by high-frequency heating molding. Therefore, the bright part 11 is also held by the lower mold 24. Moreover, the molding base 13 is only slightly re-foamed from its semi-foamed state. Therefore, the pressure inside the molds 24 and 25 is not very high, and the bright part 1
No flow occurs in 1. Therefore, even if it has the bright part 11, the resin decorative molding 10 can be molded into an irregular shape.

a, 15a may not be used in some cases,
It may be used as necessary.

There are also 6. In this modified embodiment as well, as in the embodiment shown in FIG.
A molding base 29 made of foamed resin that holds the bright part 27, and a surface of the molding base 29 and the bright part 27.
It has a molding skin part 28 that covers both edges of the molding.

る。 Then, the foamed resin molding base 29 that has been foamed during extrusion molding is re-foamed according to the mold surface shape during high-frequency heating molding. The curvature of the back surface of the molding base 29, which is the mounting surface for the vehicle body, is continuously changed in the longitudinal direction of the molding, for example, R300, R300, R300, R300, R300,
It is made to take a shape like R500 or R800.
これにより、モール２６が粘付される車体曲率

As a means for solving the problems of the present invention, the bright part and the resin base are integrally molded with a constant cross section by extrusion molding, and then cut into a predetermined length to form a molding piece. Furthermore, the back surface of the molding base can be removed to give it an irregular shape.
しかしながら、切削のため取り付け面たるモー
