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.

迫られる問題点の発生をみた。(Problem to be solved by the invention) In recent years, as consumer tastes have become more sophisticated and diversified, these composite skin materials are required to have higher quality and thickness, and the composite skin materials themselves are also becoming thicker. Demand is increasing for laminated materials made of large dissimilar materials and composite skin materials made of solid and foam layers. When manufacturing such a thick composite skin material by slush molding, heating only from the back side of the mold makes it difficult to heat uniformly over the entire area of the skin material. We have seen the occurrence of problems that need to be solved in obtaining composite skin materials.

The portion of the foamed layer remote from the molding cavity surface of the mold lacks natural heating, resulting in uneven foaming, making it difficult to obtain a homogeneous product.

In addition, 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, resulting in deterioration of the quality of the layer.

。That is, the first method for molding a composite skin product according to the present invention includes heating a slush molding die as necessary;
A thermoplastic resin material is put into the molding cavity of the mold, a semi-fused material is left on the cavity surface by heating the mold, and after the excess material is discharged, a thermoplastic resin material whose constituent material is different from the above material is removed. The different materials are reinjected, the excess material that has been melted and bonded in layers in the cavity is discharged again, and the heating medium is heated from the layered material side of the mold cavity surface in parallel with the heating from the back side of the mold. After curing the resin material,
It consists of a process of cooling the mold and demolding the molded composite skin material, and the second invention, that is, a molding device for composite skin material, is capable of heating and cooling the back side, and has a mold opening. Directly below the molding section, which has a slush molding die that can be positioned in either the up or down direction and is supported in a rotatable manner, a track is laid. Each trolley includes a box-shaped auxiliary heating section capable of ejecting a heating medium toward the cavity surface of the mold forming section, a thermoplastic resin material made of different constituent materials, and a box-shaped auxiliary heating section capable of ejecting a heating medium toward the cavity surface of the mold forming section. Reservoir tanks, which are connected to the sides in a sealed manner and are rotatable together with the mold forming section, are each arranged on a lifting device installed on a truck.

り脱型される。(Function) The slush molding mold is preheated from the back side of the mold as necessary, and the mold cavity surface is facing downward.
The reservoir tank containing the resin material located directly below rises and connects with the molding part in a sealed manner, and the molding part and the reservoir tank rotate up and down 180 degrees as one, and the inside of the cavity opens upward. The material is charged into the tank, and part of the resin material adheres to the cavity surface in a semi-gelled, semi-molten state due to the heating of the mold. 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 with different constituent materials are injected into the mold with the side layer adhered to the cavity surface by repeating the connecting rotation operation of the molding part and the tank, and the cavity is heated by heating the mold. Two resin composite layers are attached to the surface, and after the molding part and 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. Close the cavity surface 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. Even in the case of a thick composite skin body that is heated, each new section is cured evenly, 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.

複合表皮材を得ることができる。(Effects of the Invention) The present invention provides the following advantages: While heating a slush mold, a resin material for solid layer molding is first introduced into the cavity surface of the mold,
Excess resin material is discharged, leaving a part of the resin material attached to the cavity surface in a semi-molten state, and then a different material with a different constituent material from the resin material, such as a resin material for foam layer molding, is re-injected into the metal. By charging the solid layer material into the mold cavity, the molten solid layer material captures the subsequent foam layer material, making it easier for the second layer material to adhere to the cavity surface. By heating the cavity surface, more specifically the resin layer, especially the foam layer side, in parallel with the heating from the back side, the curing process progresses uniformly for each layer and layer, creating a homogeneous composite skin material. In particular, when one layer constituting the composite skin material is a foam layer, heat treatment from the foam layer side can produce a composite skin material that has a foam layer that is not evenly foamed and is firmly bonded to the solid layer. Obtainable.

るべきものがある。In addition, in this molding device, the molding section, which is rotatable and swingable and is equipped with a molding die and a heating/cooling mechanism, is installed above, and the resin is guided by a track laid below. 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 transfer dissimilar resin materials to the molding section at different times. Inputting, discharging excess resin material, and auxiliary heating from the mold cavity surface can be performed quickly and easily, as well as attaching and detaching the molding section and reservoir tank, and joining and separating the molding section and auxiliary heating section. Since 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.
