Abstract

PURPOSE:To intend such as elimination of formed traces by forming a recessed place at such as a material throwing port existing on the surface of a foam compact, and fitting such as a mirror into the recessed place, in the case of a synthetic resin foam particle compact with a core material buried therein. CONSTITUTION:A cavity mold for fixing a core material 2 is formed with a recessed part 5 in a desired position in which a mirror 4, etc., is fitted. On the other hand, a material throwing port 6 is formed in a desired position depressed more than the recessed part 5. And then, after clamping the cavity mold coincidently upon a core mold, a prescribed material is filled up into these molds to form a foam resin compact 1 to be a sun visor main body. Still more the foam resin compact 1 is covered with a vinyl chloride sheet 3 and after respective parts are welded with a welder, such as the mirror 4 and a cover 7 are attached to obtained a sun visor with a mirror. Thus, a sun visor provided with such as a mirror 4 is simply and toughly formed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a lean visor for motor vehicles with mirrors and/or lamps.

[Conventional technology]

Conventionally, temporary wooden or synthetic resin sheets or polyurethane foam sheets have been used as sun visors for the sole purpose of providing sun protection.However, temporary wooden or synthetic resin sheets are hard and have safety concerns. On the other hand, polyurethane foam sheets have problems such as being soft and sagging, and also tend to deteriorate and lose their shape.

Therefore, in order to solve these problems, styrene resin foam (Utility Model Application Publication No. 153222/1983) or Δrefine resin foam, such as polypropylene resin foam (Utility Model Application Publication No. 1987-153222), etc.
53624), etc., has been proposed using a synthetic 4- or 1-fat foam.

[Problem to be solved by the invention]

However, although these have the effect of improving the synthetic resin foam, they are not functionally sufficient.
There is a problem in that molding marks (hereinafter abbreviated as molding marks) of the Ikkyo material inlet and/or mold release bottle remain on the foamed particle molded product.
Several colors were desired.

It is an object of the present invention to solve the problems of non-viral properties using conventional foams, and to provide a foam visor that has more functions and has improved the problem of molding marks. It is something.

(Means for Solving the Problems) Therefore, as a result of various studies, the present inventors intentionally depressed a portion of the molding mark, preferably including its peripheral portion, from the surface of the molded product, and placed a mirror and/or Alternatively, they have discovered that the above problem can be solved by installing a lamp, and have arrived at the present invention.

The present invention provides a sun visor comprising a synthetic resin foamed particle molded article in which a core material is embedded and covered with a covering material.
To provide a sun visor, characterized in that a mirror and/or a lamp is set in a recess provided in a portion of the surface of the foamed molded product that includes the raw material input port and/or the trace of the mold release pin. It is.

The foamed particle molded product used in the present invention can be any synthetic resin foamed particle molded product, but preferably a polyolefin resin foamed particle molded product, for example, foamed particles of polyethylene, polypropylene, a copolymer thereof, or a mixture thereof. A molded product, preferably a polyethylene resin foamed particle molded product, most preferably a
- Density 0.925 described in Publication No. 11975 -
〇, 940 g/m of polyethylene resin particles were cross-linked, then the particles were impregnated with a foaming agent, and after preferentially volatilizing the bubbles on the surface of the particles, a foaming treatment suitable for metal objects was carried out. to form foamed particles that have a skin thickness that is about three times or more larger than the thickness of the inner layer structure, and then fill the foamed particles into a mold after being treated to provide expansion ability. The foamed particles are fused together while avoiding heating and expansion pressure, and the resulting molded product is further aged at a temperature of 60°C or higher for at least 611°C to substantially eliminate the interparticle gaps on the surface. It is a polyethylene foamed particle molded product that does not have a polyethylene foam particle molded product, specifically, a foamed particle molded product using Metsu (trademark) manufactured by Asahi Kasei Kogyo (Tai).

Next, a method for manufacturing the sun visor of the present invention will be explained.

First, a metal wire, for example, a copper-plated wire, is placed in a mold designed to have four parts for attaching a mirror and/or lamp to the place where the raw material input port and/or mold release pin are placed. After setting the core material made by bending, the mold is tightened. This is filled with a predetermined amount of raw material PE beads, heated, and foam-molded. Next, after cooling the mold, the mold was opened and the molded ring-by-tear body was taken out.After 1 degree, it was covered with a facing material, and the four parts for installation provided on the molded body (where the raw material input hole remains) were removed. Attach a mirror and/or lamp to the chain (attached to the chain).At this time, you can also attach a mask made from the covering material to the chain.

The covering material may be polyvinyl chloride, a sheet, cloth, or a laminate thereof.

Furthermore, although the above is an example of an integrally molded foamed particle molded product,
Alternatively, it is also possible to manufacture the product by making a foam-molded half-wall for 2 minutes [υ], setting the core material therein, and bonding the core material together with adhesive or heat fusion.

〔Example〕

Example 1 A core material having a substantially parallelogram shape with a long side of 40 cm and a short side of 13 cm as shown by 2 in FIG. 1 is manufactured by bending a 3#φ copper-plated horizontal wire. This core material 2 is fixed in a cavity mold. This cavity mold is designed so that a recess 5 into which the mirror 4 in Fig. 2 can be inserted is formed at position 5 in Fig. 1, and a raw material inlet is provided at position 6, which is further depressed from the recess 5. Next, after fitting this cavity mold to the core mold and clamping the mold, polyethylene foam beads (Asahi Kasei Kogyo Co., Ltd. (Tai Seimetsu 030 times product)) are filled into the mold.

Next, 1.2-2. After heat-sealing with water vapor at OK'j/crA pressure for 20 to 30 seconds, cooling to room temperature with cooling water at about 20'C to form a foamed particle molded body 1 with a non-visor body. do.

This foamed particle molded product 1 is removed from the mold and aged, then covered with a PVC sheet 3 and fused with a welder, and then the mirror 4 and the lid 7 in Figure 2 are attached. A phosphor visor with a mirror is obtained.

Incidentally, if the lamp is to be used for compensation, it can be done in the same manner as in the case of the mirror described above.

In the sun visor with mirror of the present invention, the polyethylene foam particle molding used has extremely good moldability and is also strong, so even when used for a long time, it did not sag or sag at all. The texture was also extremely good.

One of the features of the sun visor of the present invention is that by changing the shape of the mold, it can be made into a U-shape that matches the top of each vehicle, making it easier to install on vehicles than conventional products. It is easy to put on and can be attached perfectly.

〔Effect of the invention〕

The automobile sun visor of the present invention has a mirror and/or lamp that can be used for cosmetic purposes attached to the original sunshade, making it more convenient and eliminating the problem of molding marks on the foamed particle molded product. This has the effect of being able to solve the problem.

In addition, the sun visor of the present invention has good moldability when a specific polyethylene resin foam particle molded product is used,
In addition to being able to be easily and freely molded into a shape that fits the roof of a car, it is extremely strong without sagging or sagging even after long periods of use, and has a firm feel and good appearance. It also has the effect of giving a sense of luxury.
