The present invention relates to a hot press molding die used for forming an uneven pattern on a laminated sheet in which a front surface material is laminated on the front surface of a flexible foamed synthetic resin sheet and a back surface material is laminated on the back surface. Recently, a surface material has been laminated on the surface of a cotton or flexible foamed synthetic resin sheet, and a backing material has been laminated on the back side, as a cushion material or surface material for the seats of vehicles or furniture, or as a cushion material or surface material for bedding. There is a demand for a laminated sheet with an uneven pattern on its surface from the viewpoint of texture, touch, or design. Conventional methods for forming the uneven pattern on laminated sheets using cushioning materials such as cotton or flexible synthetic resin foam as core materials include quilting methods, high-frequency welding methods, and hot pressing methods. They are selected and used as appropriate in terms of their materials, characteristics, and workability. The present invention is directed to a heating method used in conventional hot press molding in which a laminated sheet having an uneven pattern and a laminated sheet having a core material of a flexible foamed synthetic resin sheet that can be deformed by hot press are shaped by a hot press method. This invention relates to improvements in press molding dies. Conventionally, when forming an uneven pattern on a laminated sheet using a flexible foamed synthetic resin sheet as a core material by a hot press method, a thin plate linear shape arranged in an appropriate uneven pattern as shown in Fig. 2 was used. A hot press mold consisting of an upper mold 3 having a pressing mold 4 and a lower mold 6 with or without a pressing mold is used, and these molds are placed between a hot press upper plate body 1 and a hot press lower plate body 2. A laminated sheet 13 with a flexible foamed synthetic resin sheet 8 as a core material is placed between the upper mold 3 and the lower mold 6, and then the laminated sheet 13 is placed between the upper and lower hot press molds. The material was heated and pressed using a heat press. A sheet having an uneven pattern as shown in FIG. 4 was thus obtained. The present invention improves the heat press molding mold used in the conventional method for forming an uneven pattern, thereby creating a tight uneven pattern that is clearer than the uneven pattern obtained by the conventional method. The purpose is to obtain a laminated sheet with a pattern. The mold for hot press molding of a laminated sheet having an uneven pattern of the present invention is used when hot press shaping a laminated sheet in which a surface material is laminated on the front surface of a flexible foamed synthetic resin sheet and a backing material is laminated on the back surface. In the mold for hot press molding used, the upper mold is made of a material with high thermal conductivity and has a pressing mold with an arbitrary line pattern, and the lower mold is a plate plate made of a material with high thermal conductivity. , on this plate, which is also made of a material with high thermal conductivity, the distance between the side surface of the upper die and the tip of the lower die is narrower than the thickness of the flexible foamed synthetic resin sheet, and the line of the press die of the upper die is It is made by standing up a stamp in the shape of a line pattern that is slightly smaller than the pattern.
It is composed of an upper mold and a lower mold. The flexible foamed synthetic resin sheet 8 used as the core material of the laminated sheet 13 includes soft or semi-rigid polyurethane foam, polyvinyl chloride foam, polyethylene foam, etc.
In particular, it is preferable to use a soft or semi-rigid polyurethane foam having open cells. As the surface material 7, woven fabric, knitted fabric, non-woven fabric, synthetic resin leather, etc. can be used, but it is preferable that it has air permeability. As the back material 9,
The same surface materials as the above-mentioned surface materials can be used, but materials with relatively low elasticity such as gold cloth, nonwoven fabric, and cheesecloth are particularly preferred. The conditions for press shaping are a heating temperature of 150°C to 220°C and a pressure of 1 kg/kg.
cm 2 to 5 Kg/cm 2 and press time 0.5 to 5 minutes. The hot press molding mold of the present invention is composed of an upper mold 3 and a lower mold 6, as shown in an embodiment in FIG.
0 is formed. The upper mold 3 is formed of a plate 4' made of a highly thermally conductive material and a mold 4, and a heat insulating material 12 is filled in the portion surrounded by the thin plate linear mold 4 formed on the upper mold 3 in an arbitrary pattern. It is arranged. When this heat insulating material 12 is provided, the effect of forming the uneven pattern is enhanced compared to the case where it is not provided, but even if the heat insulating material 12 is not provided, the effect of forming the pattern aimed at by the present invention may be impaired. Nothing happens. As the heat insulating material 12, a material with high heat resistance is suitable.
Glass wool, asbestos, rock wool, etc. can be used. The lower mold 6 has a plate 6' made of a material with high thermal conductivity, and on this plate there is a line pattern that is slightly smaller than the line pattern of the pressing mold 4 of the upper mold 3, and the upper mold 3 and the lower mold 6 are formed.
A press die 10 formed in a linear pattern is provided so that it can come into almost contact with the press die side surface 4'' of the upper die when the two are put together.This press die 10 is made of a material with high thermal conductivity.In this lower die 6, In this method, the side cross-sectional shape of the pressing mold 10 is formed at an angle to form an inverted eight figure shape.
The shape of the mold is not particularly limited to that of this embodiment as long as it can be pressed against the mold side surface 4'' of the upper mold 3.
The material has a thermal conductivity of 50 Kcal/mh°C or more at °C, for example, copper, aluminum, brass, iron, etc. can be used. The distance between the mold side surface 4'' of the upper mold 3 and the tip 10' of the mold 10 of the lower mold 6 is preferably 20% to 60% of the flexible foamed synthetic resin sheet 8 to be molded, and the height of the mold 10 is 5 mm. ~20 mm is sufficient. When using the hot press molding mold of the present invention to form an uneven pattern on the laminated sheet by placing the laminated sheet between the molds and hot pressing, the laminated sheet The sheet 13 is heated and pressed by the upper mold 4 and the plate 6' of the lower mold 6, and at the same time is pressed upward from the back surface of the laminated sheet by the lower mold 10 and the inner surface 4 of the upper mold 4. After continuing hot pressing for a certain period of time, when the laminated sheet was released from the hot press mold, an uneven pattern with a cross-sectional shape as shown in Figure 3 was formed. A laminated sheet can be obtained.As shown in FIG. 2, when the laminated sheet 13 is heated and pressed to form an uneven pattern using a conventional hot press molding die, the laminated sheet 13 is not suitable for hot press molding. Since heating is performed from both sides of the upper mold 3 and lower mold 6, and only the pressing mold 4 and lower mold 6 of the upper mold are heated and compressed, the flexible foamed synthetic resin sheet 8' cannot be restored. Not only does the power decrease;
Since it is not able to fully recover due to the pressure exerted by the surface material 7', only a molded sheet having a shallow uneven pattern as shown in FIG. 4 can be obtained. The laminated sheet formed with the uneven pattern obtained by the present invention has a cross-sectional shape as shown in FIG. is formed, and the uneven pattern appears deeper and more clearly than in conventional ones.Since the heat-compressed pattern is formed on both the front and back sides of the laminated sheet, this part becomes harder, and therefore The concavo-convex pattern formed with strong pattern-forming force is difficult to collapse and has good shape retention. In addition, since grooves are also formed on the back side of the laminated sheet, when this laminated sheet is used as a cushion body or a skin material for a cushion, the elasticity of the flexible foam synthetic resin sheet material itself and the sheet's In addition to the cushioning effect resulting from its structure, it has extremely good cushioning properties. Furthermore, the adhesive strength of the pressed portion is improved, making it difficult for the front and back materials and the core material to separate. Examples will be explained below. [Example 1] Flexible foamed synthetic resin sheet using the material Γ Soft polyurethane foam sheet with a thickness of 10 mm and a density of 20 kg/m 3 Surface material 7 Nylon woven backing material 9 Nylon non-woven fabric The above materials were laminated to form a laminated sheet. used. A hot press mold used was a mold having the structure shown in FIG. 1. The height of the mold 4 of the upper mold 3 is 55 mm.The insulation material 12 is filled with glass wool to a thickness of 40 mm.The interval between the molds 4 and 4 of the upper mold is 50 mm.The lower mold 6 is made of iron plate 6'. Pressing molds 10 made of iron and having a height of 7 mm are arranged in an inverted eight shape on a plate. After the above laminated sheet is heated and press-molded using the above mold at 180°C for 2 minutes, the uneven pattern sheet shown in Fig. 3 is obtained. The height of the convex portion h 1 was 9.5 mm. [Comparative Example 1] A laminated sheet made of the same material as in Γ Example-1 was used. A hot press mold using Γ A mold having the structure shown in FIG. 2 was used. The upper mold 3 is the same as in Example-1, and is not filled with a heat insulating material. The lower mold 6 is a single plate made of iron. After hot press molding the laminated sheet using the mold described above under the same conditions as in Example 1, a shallow patterned sheet shown in FIG. 4 was obtained, and the height of the convex portions h 2 =4 mm.
