摘要： PURPOSE:To uniformize a foaming state and to enhance the integrated bonding strength of a foamed resin and a frame, by a method wherein the resin raw solution injected in a mold is allowed to flow to respective parts from the receiving port formed to the frame through a passage and injected in the respective parts in the mold through an injection port. CONSTITUTION:In such a state that a cushion frame 4 is temporarily fixed to an upper mold 2, a receiving port 6 is positioned in opposed relation to a resin injection head 3 and, when a foamable resin raw solution is injected from the resin injection head 3 in a clamped state, the resin raw solution flows to respective parts from the receiving port 6 through the pipe like internal passage 7 of a frame main body 4a to be injected in the respective parts through many small holes 8 in a dispersed state. Therefore, the foamable resin raw solution injected in the respective parts of the mold in a dispersed state starts foaming in this state and, on the side of the rear, molding is completed in such a state that the frame 4 is unified in an embedded or semi-embedded state. At the point of time when molding is completed, the hollow interior of the frame main body 4a is filled with a foamed pad be contribute to the enhancement of the integrated bonding strength of the foamed pad and the frame 4.

摘要： PURPOSE:To position a supporter material positively to a top force formed in a vacuum mold, and to prevent adhesion onto the top force of the stock solution of a foaming synthetic resin by a synthetic resin film joined with the supporter material by shaping the top force in the vacuum mold and joining the synthetic resin film with the rear side of the supporter material. CONSTITUTION:A supporter material 32 is disposed to the top force 23 of a foam molding die 21, the stock solution of a foaming synthetic resin is injected into a bottom force 22, and a pad material 35 is foam-molded unified with the supporter material 32 under the state in which the top force 23 is mold-registered to the bottom force 22. In this case, the top force 23 is formed in a vacuum mold, a synthetic resin film 33 is joined with the rear side of the supporter material 32, the laminate of the synthetic resin film 33 and the supporter material 32 is sucked to the top force 23 under a vacuum, and the pad material 35 is foam-molded integrally. Consequently, the sag of the supporter material 32 can be prevented, thus shaping an accurate rear shape. The film 33 is joined with the rear side of the supporter material 32, thus obviating adhesion onto the top force 23 of the stock solution of the foaming synthetic resin.

摘要： PURPOSE:To uniformize a foaming state and to enhance the integrated bonding strength of a foamed resin and a frame, by supplying the resin raw solution injected in a mold to the respective parts in the plate through a diffusion plate. CONSTITUTION:Upper and lower molds 1, 2 are engaged in such a state that the peripheral edge of a skin material 3 is held and fixed between the flanges formed to the peripheral edges of the upper and lower molds 1, 2 and a foamable resin raw liquid is injected in the molds through a resin injection head 4. Whereupon, the emitted raw solution is poured on a diffusion plate 6 and a part thereof is supplied to the lower part of the diffusion plate through through-holes 6a while the other is dripped from the peripheral edge of the diffusion plate 6 in a dispersed state. Therefore, the resin raw solution is injected in the molds while dispersed to respective parts to start foaming and foaming curing is completed in a state integrated with the skin material 3 and, on the side of the rear, molding is completed in a state unified with a cushion frame 5.

摘要： PURPOSE:To prevent noise occurrence in forming the contact to be coarse by providing a water containing layer on the appropriate position of the die surface of an upper die, and placing the layer into contact with the surface of foaming urethane during molding a pad. CONSTITUTION:A trim cover is set in a die-open state on the die surface 1a of a lower die 1 and foaming urethane liquid is poured in a certain quantity into the lower die, and as an upper die 2 is die-clamped, the foaming urethane liquid is formed and cured while being filled into the cavity formed between the upper and lower die. At this time, the part in contact with the general part of die surface 2a of a molded pad 10 becomes a compact and smooth skin layer 10a in its surface. The part in contact with porous silicon 4 comes into contact with the water contained therein, and the surface becomes a coarse surface 10b. In a state wherein the obtained pad 10 and the trim cover 14 are fabricated to the frame 12, the contacting part of the pad 10 to the frame 12 becomes the coarse surface 10b. By the coarse surface, the noise occurred through the relative slip by the coarse surface can be prevented.
