著しい効果を有する。Regarding the molding method for this door), as shown in Figure 0 below, the peripheral edge of the fabric is made of thermoplastic resin material such as polyvinyl chloride, and a high frequency welder is used to form a closed loop plate. etc. to form the fabric assembly 7, and one mold r of the injection mold.
1 For example! When the plate of the fabric assembly 7 is brought into contact with the closed-loop recess ♂a of the one mold t at θ~700C and is pressed, the next surface ≦a of the plate 4 and the tongue piece 6b are heated. Softening, while the concave part of me? a and the general surface rb, and the seal is complete. Next, one injection molding metal shop and the other molding machine together with 10,000 shops? The mold is closed, and the molten synthetic resin is poured into the cavity io in both molds r and ri.
When press-fitted, the plate 6 and one mold r are in close contact, so the molten synthetic resin // is attached to the fabric and one mold r.
However, the fabric DA is exposed on a part of the surface of the molded synthetic resin plate t2, and as mentioned above, the synthetic resin part λ,3 and the fabric DA are separated. It should be noted that the plate 6 and the recess J'a have a flat cross-sectional shape instead of a trapezoid as shown in FIG. Good Og, Effects As explained above, according to the present invention, there is no need for any elastic sheet, and the plate surrounding the outer layer (fabrics of the present invention) is brought into close contact with one side of the mold. Since the molten synthetic resin does not flow in and the fabrics are placed on the surface side of the synthetic resin board, manufacturing costs can be significantly reduced, and fabrics can be placed on only a portion of a large resin molded product (covering parts). It has remarkable effects such as being possible.
