Abstract

PURPOSE:To improve durability, design and economical efficiency ever so better, by actualizing an uneven-form part pattering characters and figures on an outer covered body surface. CONSTITUTION:A molded body 1 for a car side protector makes up some punched parts 3 patterning characters and figures. That is to say, a one-side surface 2a of a stainless beltlike core material 2 being bent in the specified sectional form forms a plastic outer covered body A while the other surface 2b forms an outer covered body B by means of cladding, respectively. An outer covered body solid part C filling up the punched part 3 is embossed out to either side of the said surface 2a or 2b and thereby a recessed part 3b or a projected part 3a patterning characters and figures is turned up on each surface of the outer covered bodies A and B whereby these parts are solidly molded by means of extrusion molding. The outer covered body A uses transparent resin while the outer covered body B uses opaque resin, and the outer covered body solid part C is embossed to the one-side surface 2a side under pressure, thus three- dimensional designing properties are improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a molded article for a vehicle side protector, etc., which has concave or convex portions such as letters or patterns on its surface, and a method for manufacturing the same.

Taking the side protector of a vehicle as an example, methods for adding letters, patterns, etc. to it include printing, painting, and injection molding. Printing and painting methods lack a three-dimensional effect and lack durability. In injection molding, it is not possible to mold long objects, resulting in high costs. Also, as another means,
There is a method of fitting a plate with letters, patterns, etc. printed onto the main part of the molding obtained by injecting or extrusion molding, but in this case, the fitted part is exposed to the outside, which impairs the appearance. There is,
Also, it takes too much time to fit it.

The present invention was conceived in view of the above-mentioned circumstances, and its purpose is to provide a molded article for a side protector for a vehicle, etc., which is excellent in durability, design, and economy, and a manufacturing method.

The gist of this invention is that a synthetic resin outer cover A is formed on one side of a band-shaped core material with transparent punching parts such as letters, patterns, etc. and bent into a required cross-sectional shape if necessary, and an outer cover B is formed on the other side.
The integral portion C of the outer cover filled with the punched portion is pressed out to one side of the one side or the other side, and letters, patterns, etc. are created on the surfaces of the outer cover A and B. It is characterized by the appearance of concave or convex parts,
The manufacturing method is to extrude a belt-shaped core material with transparent punched parts such as letters and patterns, and apply a synthetic resin outer cover A on one side of the core material and an outer cover B on the other side under molding pressure. At the same time, continuous adhesion molding with different
The integral part C of the outer cover filled with the punched part is pressed out onto one side of the core material or the other side by the molding pressure difference and is integrally extruded, and letters are printed on the surfaces of the outer covers A and B. It is characterized by the appearance of concave or convex portions shaped like patterns.

Hereinafter, embodiments of the present invention will be described in detail with reference to illustrative diagrams in FIGS. 1 and 5.

Figures 1 and 2 are perspective views of the molded body, Figure 3 is a perspective view of the core material, Figure 4 is an enlarged cross-sectional view of Figure 2 and FIG. In the figure, 1 is a molded body for a vehicle side protector, 2 is a core material, 3 is a punched part, 3a is a convex part, 3b
is the concave part, and A and B are the outer covering.

In Figs. 1 to 4, a molded body 1 for vehicle side protector, etc. (the figure shows a molded body for an automobile side protector) has a punched part 3 for letters, patterns, etc. formed therethrough and, if necessary, a desired cross-sectional shape. A synthetic resin outer cover A is attached to one side 2a of a belt-shaped core material 2 made of stainless steel or the like (C-shaped in the figure), and an outer cover B is attached to the other side 2b, and the punched portion 3 The integral part C of the outer cover filled with the above-mentioned piece is pressed out to one side of the other surface 2a, 2b, and the outer cover A, B surface is formed into a concave portion 3b or a convex shape with letters, patterns, etc. The portion 3a is exposed and integrally formed by extrusion molding. 1st
The molded body shown in the figure is made of a transparent or semi-transparent resin for the outer cover A, an opaque resin for the outer cover B, and an integral part C of the outer cover is extruded to one side 2a, and the transparent resin is applied to the surface of the outer cover A. Convex portion 3a through which the opaque resin can be seen through
It brings out the three-dimensional design and enhances the three-dimensional design. In the molded body shown in FIG. 2, the outer covers A and B are made of the same resin, for example, a colorless transparent or translucent resin, and the integral part C of the outer cover, which has a darker tone, is extruded onto the other surface 2b.
A concave portion 3b that is easily discernible is exposed on the surface of the outer cover A to enhance the design that gives the impression of a concavity. Note that there is a concave portion 3 on the surface of the outer cover B of the molded body 1 in FIGS. 1 and 2.
It goes without saying that the convex portion 3b or the convex portion 3a is exposed. The outer coverings A and B have convex and concave portions 3a,
Any resin may be used as long as it improves the design of 3b.

To explain the manufacturing method with reference to FIG. 5, a belt-shaped core material (made of stainless steel, aluminum, steel, etc.) 2 with transparent punching parts 3 for characters, patterns, etc. and bent into a C-shaped cross section is extruded into an extrusion molding machine (not shown). ), that is, the core material 2 is passed through a core material cylinder 5 installed inside a crosshead mold 4 directly connected to the molding machine.
The core material 2 is made to pass through a discharge port 6 that communicates with the conductive holes 6a and 6b of the synthetic resin jackets A and B, which will be described later, through the conductive hole 5a of The synthetic resin jacket A that has been guided through
On the other side 2b, the synthetic resin jacket B guided through the guide hole 6b by the other extruder is continuously applied and molded at different molding pressures, and at the same time, the punched part 3
The integral part C of the filled outer cover is forced out to one side of the core metal 2, the other surface 2a, 2b by the molding pressure difference, and integrally extruded from the discharge port 6, and the outer cover is A molded body 1 for a vehicle side protector is obtained by exposing convex portions 3a or concave portions 3b in the shape of letters, patterns, etc. on the surfaces of A and B. The molded body in FIG.
Convex portions 3a are formed on the surface of the outer cover A, and concave portions 3a are formed on the surface of the outer cover A in the case shown in Fig. 2, which is integrally formed. This molded body 1 is cut to a required length, treated at both ends, and assembled into an automobile as a rear side protector.

The manufacturing method of this invention has the advantage of being able to be manufactured continuously by extrusion molding and is economical. This invention can be applied to a wide range of applications other than vehicles, by simply extrusion molding and cutting into long, short, or required lengths. In this invention, by appropriately selecting the materials of the core material 2 and the outer coverings A and B, unique design effects such as deep glitter, three-dimensionality, and a recessed feeling that cannot be seen with conventional construction methods can be obtained. Since the concave and convex portions 3a and 3b are integrated with the outer cover, the durability is outstanding and is superior to that of conventional construction methods.

As described above, according to the present invention, all the problems of the prior art such as durability, design, forming of long objects, and cost can be solved, and the effects are considerable.
