ができないなどの問題点があった。However, in such conventional molding manufacturing methods, in the case of extrusion molding, the core material 4 and decorative film 5 are exposed at the cut end, so it is necessary to separately form the end piece. The problem is that Paris is formed between the two countries. In the case of injection molding, since the resin is injected under high pressure, it is difficult to provide the core material 4 and the decorative film 5 at predetermined positions, and even if these are not provided, the appearance may deteriorate and molding distortion may occur due to uneven flow of the resin. There have been problems such as the molding of thin or wide products.
この発明は上記問題点を解決するためのもので。This invention is intended to solve the above problems.

することにより、外表面に固着することができる。[Function] In the molding manufacturing method of the present invention, a plurality of sheets of thermoplastic resin having a predetermined size are laminated in the cavity of a mold, and the sheet materials are heated and softened below their melting temperature and then the mold is clamped. The molding is manufactured by compressing the sheet material, welding the sheet material together, and fluidly filling the cavity. At this time, the core material can be embedded by interposing it between the sheet materials, and the decorative film can be fixed to the outer surface by compressing it to form a predetermined shape and immediately placing it in a mold and applying pressure again. I can do it.
以下、この発明を図面の実施１例により説明する。 The present invention will be explained below with reference to an embodiment of the drawings.

In FIG. 0, which is a sectional view corresponding to B-B, 11 is a cavity mold, and 12 is a core mold, which constitutes a mold, and has a cavity 13 having a shape corresponding to the molding 2 therein. A recess 14 corresponding to the outer surface of the molding 2 is formed in the cavity mold 11, and a protrusion 15 corresponding to the decorative film 5 is formed. A convex portion 16 corresponding to the inner surface of the molding 2 is formed on the core mold 12 . 17, 18, and 19 are sheet materials made of thermoplastic resin (soft PVC in the example).

６０℃に加熱しておく。The materials 17, 18, 19 and the core material 4 coated with heat-sensitive adhesive on both sides or having a plurality of through holes formed therein are laminated in the cavity 13 of the Qin 114. At this time, the recess 1 of the cavity mold 11 is the part corresponding to the outer surface of the molding 2.
The sheet material 17 on the fourth side is dimensioned to cover almost the entire surface of the cavity 13, and the core material 4 is interposed between this sheet material 17 and an adjacent sheet material 18. The core material 4 is dimensioned so that it does not reach the inner circumference of the cavity 13, and the sheet materials 17 to 19 and the core material 4 are dimensioned in advance so that they have almost the same shape and the same capacity as the molding 2, but have a slightly larger capacity than the cavity 13. The cavity mold 11 and core mold 12 are determined to be 80 to 1
Heat to 60℃.

固着されてモールディング２が製造される。Next, when the mold is clamped and compressed in the heated state, the sheet material 1
The surfaces of 7 to 19 are melted and integrated with the core material 4 buried therein, and flow and fill the entire area inside the cavity 13. Immediately after forming the predetermined shape in this way, the mold is opened, the decorative film 5 is set on the part corresponding to the convex portion 15, and the mold is clamped and compressed again, so that the decorative film 5 is fixed to the outer surface and the molding 2 is manufactured. Ru.
成形型はモールディング２の形状、艶等をよくするため
に離型前に３０〜８０℃に冷却するのが好ましい。In order to improve the shape and gloss of the molding 2, the mold is preferably cooled to 30 to 80° C. before being released from the mold.

れ、薄肉、幅広のものでも成形可能である。The molding 2 manufactured in the above manner has a good appearance without uneven flow by forming the outer surface with the integral sheet material 17, and has little distortion and no deformation, and the core material 4 is buried. This provides rigidity and prevents expansion and contraction, prevents warping even in the case of an asymmetrical cross section, and allows molding of thin and wide products.

適用できる。In addition, in the above explanation, it is preferable that the sheet materials 17 to 19 are heated in advance and set in the mold, but they may be heated after being set in the mold.The core material 4 and the decorative film 5 are not necessarily necessary. As for the material of the sheet materials 17 to 19, soft PVC or any other thermoplastic synthetic resin can be used. Furthermore, the present invention is not limited to side moldings, but can also be applied to the manufacture of other moldings such as bumper moldings.
