Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a slush molding method for composite skin materials and a molding device thereof, and in particular, the present invention is directed to slush molding for thick composite skin materials. . An example of a composite skin material is a composite skin that is a part of automobile interior parts such as console boxes, instrument panel pads, and grab boxes.As a final product, this skin material can be used as a foam layer, This is a member for covering the outside of the core material for shapes.

(Prior art) Molding of composite skin materials by slush molding is a relatively simple method, including precise surface patterns.
Because it can produce accurate composite skin materials, it is mainly used as skin materials for automobile interior parts, and is widely used in various other industrial fields.

Conventional slush molding includes a method in which a heating oil supply pipe is installed on the back of the mold, a method in which heating wires are buried in the mold, and a method in which a heating wire is buried in the mold, as shown in Japanese Patent Publication No. 54-10581. Vinyl chloride is placed in a mold that is heated from the back side by bringing the back side of the mold directly close to the flame, or by immersing the back side of the mold in heat transfer oil or heated metal powder. After introducing resin plastisol or powder and semi-gelling or semi-melting a part of the material on the molding cavity surface of the mold, the excess material is discharged and a new, different type of material is added. After putting in the resin material and welding the resin material in layers, the excess is discharged again, and the molten resin is solidified by heating from behind the mold.Then, the mold is cooled and the composite skin material is formed. It was being molded.

(Problems to be solved by the invention) In recent years, as consumer tastes have become more sophisticated and diversified,
These composite skin materials are also required to be of higher quality and heavier, and there is a high demand for composite skin materials themselves such as laminated ones made of thick different materials, and composite skin materials made of solid layers and foam layers. It is worshiped. When manufacturing a thick composite skin material using slush molding, heating only from the back side of the mold makes it difficult to heat the skin material uniformly over the entire area. In obtaining composite skin material,
We saw the emergence of problems that needed to be resolved.

In particular, when molding a skin material with a foam layer on the inside, the portion of the foam layer away from the molding cavity surface of the mold lacks natural heating, resulting in uneven foaming and making it impossible to obtain a homogeneous product. It was difficult.
In addition, in the manufacturing process of composite skin materials, after the surface layer has been formed, a different material is filled on the inside of the surface layer.
Heat treatment is performed again, but for example, the foamed vinyl chloride layer has a thermal conductivity of about 0.031 Kcal/m・Hr°C, so it is difficult to gel or melt and foam the inner layer sufficiently. It is also difficult to obtain high-quality products from the mold, and if the temperature of the mold is forcibly raised to increase the degree of gelation or melting of the inner layer, the surface layer in contact with the cavity surface of the mold will be overheated, causing the problem. This also resulted in alteration of the layer.
In addition, when molding composite skin materials with different constituent components or using different types of resin materials, the materials may be introduced into the mold at different times, and the heating operation of the mold may be incorporated in between. The work required skill and was time-consuming.

It is an object of the present invention to solve these problems inherent in conventional slush forming means and to provide a simple method of slush forming a composite skin material regardless of the size of the molded product, and an apparatus therefor. .

(Means for Solving the Problems) In order to achieve this object, the present invention has the following configuration.

That is, in the first method of molding a composite skin material according to the present invention, a slush molding mold is heated as necessary, a thermoplastic resin material is put into the molding cavity of the mold, and the mold is heated. By heating the mold, a semi-fused material is left on the cavity surface, and after discharging the excess material, a different material with a different constituent material from the above material is reintroduced, and the layered material is melted and bonded inside the cavity. The surplus is discharged again, and in parallel with the heating from the back side of the mold, a heating medium is also ejected from the layered material side of the mold cavity surface, and after curing the resin material, the mold is cooled, and the molding is completed. The second invention, that is, the molding device for composite skin material, is capable of heating and cooling the back side, and the mold opening can be positioned in either the upper or lower direction. A track is laid directly below the molding section that has a slush molding die that is rotatably supported, and a heating medium is applied to each of the plurality of carriages running on the track.

(Function) The slush molding mold is preheated from the back side of the mold as necessary, and with the mold cavity surface facing downward, the reservoir tank containing the resin material located directly below rises and the mold is heated. The molding part and the reservoir tank are connected in a sealed manner to the molding part, and the molding part and the reservoir tank rotate up and down 180 degrees as a unit, and the material is introduced into the upwardly opened cavity by the tank, and part of the resin material is heated by the mold. adheres to the cavity surface in a semi-gelled, semi-molten state. Thereafter, the forming part and the tank are rotated back to their original positions, and the excess material is discharged into the tank. Next, powdered resins of different types or of different constituent materials are poured into the mold with the upper layer adhered to the cavity surface by repeating the connecting rotation operation between the molding part and the tank, and the mold is heated to form a layer on the cavity surface. Two resin composite layers are attached to the tank, and after the molding part and the tank are returned to their original positions, the excess material is discharged into the tank and the reservoir tank is lowered and separated from the molding part. Next, the reservoir tank and its position are changed, and the box-shaped auxiliary heating section is moved to a position directly below the molding section with the cavity surface of the mold facing downward. occlude and join. In parallel with the heating operation from the back of the mold, the heating medium is ejected from the auxiliary heating section to the mold cavity surface, more specifically to the resin composite layer surface, and the resin composite layer attached to the mold cavity surface is heated from both sides. In the case of a composite skin body that is heated and has a large wall thickness, the curing progresses approximately evenly in each part, and a uniform skin body is formed in each part. After heating, a cooling medium is supplied to the mold section, and the molded skin body is removed from the mold cavity surface.

By adopting a mechanism that allows the reservoir tank containing the material and the auxiliary heating section to freely move directly below the molding section and rise to the molding section position, it is possible to reduce the time difference between dissimilar resin materials to the molding section. Inputting resin material, discharging excess resin material, and auxiliary heating from the mold cavity surface can be performed quickly and easily, and it is also possible to attach and detach the molding section and reservoir tank, and connect and separate the molding section and auxiliary heating section. Because it can be performed accurately and quickly, it can greatly contribute to improving the efficiency of a series of operations.Also, by heating the composite skin layer from both sides of the mold in parallel, it is possible to homogenize the product and improve mass production. There is something to be done.
