摘要： PROBLEM TO BE SOLVED: To reduce apparatus costs and to facilitate the adjustment of the pressure of a cavity. SOLUTION: A raw material synthetic resin R1 is converted into a resin R2 in which gas is dissolved by diffusing carbon dioxide gas supplied into the bush chamber 26 of a foaming raw material preparation apparatus 20 which is adjusted in a prescribed temperature environment in the molten resin R1. Then the resin R2 is injected into the cavity 34 of a mold 30 for compression molding, and an upper mold 32 is lifted promptly to sharply reduce the pressure of the cavity 34 so that foam is formed in the cavity 34.

摘要： PROBLEM TO BE SOLVED: To provide a molding die which can supply compressed fluid stably to a thermoplastic resin without leaking the fluid from the gap between the resin and a cavity outside the mold when the fluid is supplied to the resin with the cavity of the die filled with the molten resin. SOLUTION: A compressed fluid supply member 26 for supplying the compressed fluid to the molten thermoplastic resin 4 packed in the cavity of the molding die 21 is set in a lower mold 23. Projections 23a are formed continuously to surround the compressed fluid supply port 26a of the supply member 26 in the lower die 23. In this way, the fluid supplied from the supply port 26a is prevented from leaking from the gap between the molten resin 4 and the lower mold 23 outside the molding die 21 and can be supplied surely into the molten resin 4 so that a hollow part 4a can be formed stably.

摘要： PROBLEM TO BE SOLVED: To produce a multilayered molded article at a low cost without generating the damage or cushioning properties caused by the collapse of a foam layer, by constituting a skin material of two or more kinds of urethane foam layers different in density and positioning low density urethane foam layer on the surface side of the molded article and positioning a high density urethane foam layer on a base material side. SOLUTION: An urethane foam layer 3 is constituted of two kinds of foam layers respectively comprising soft or semihard polyurethane foams different in density. As a backing material, a nonwoven fabric of a natural fiber or a synthetic fiber such as a polyamide fiber or a synthetic resin sheet or film is used and, as a thermoplastic resin 7, polyethylene or polypropylene is used. A skin material consists of a skin layer 2, the urethane foam layer 3 consisting of two layers different in density and a backing layer 4, and the urethane foam layer 3 is arranged so that a low density urethane foam layer 3-1 is provided on the side of the skin layer 2, and a high density urethane foam layer 3-2 is provided on the side of the backing layer 4. By this constitution, the damage of cushioning properties caused by the collapse of the foam layer is prevented and a multilayered molded article can be produced at a low cost.

摘要： PROBLEM TO BE SOLVED: To prevent warpage or deformation easily through a simple device by a method wherein a slide block is positioned at advancing position toward opposing mold surfaces and molten thermoplastic resin is supplied between the molds, then, the molds are closed to pressurize them and, thereafter, pressurized fluid is poured into the molten thermoplastic resin and the slide block is retreated. SOLUTION: Molten thermoplastic resin is supplied between a pair of male and female molds through a resin passage 10 under a condition that a slide block 3 is positioned at advancing position toward the opposing mold surfaces, then, the female mold 1 and/or the male mold 2 are moved by a moving means 4 to clamp the molds and the molten thermoplastic resin is pressurized to fill the same into a cavity 6. Subsequently, pressurized fluid is poured into the molten thermoplastic resin through a fluid pouring member 8. The fore end of the fluid pouring member 8 is a pressurized fluid pouring port 7 while the rear end of the same is communicated with a fluid passage 9. Simultaneously with the pouring of the pressurized fluid, the slide block 3 is retreated and a hollow part is formed. Thereafter, the thermoplastic resin in the cavity 6 is cooled and solidified.

摘要： PROBLEM TO BE SOLVED: To improve outer appearance by forming a continuous projection at a marginal corresponding position of a non-designed surface side cover part of an air bag cover integrally molded vehicle trimming part, forming a groove type recessed part on a designed surface side cover part margin and forming one end of a resin interface of a resin connecting part so as to make contact with the groove type recessed part. SOLUTION: A continuous projection 4 is formed at a position corresponding to a marginal part of an air bag cover 1 of a non-designed surface side (back side) of a vehicle trimming part, and a groove type recessed part 5 continued in correspondence with a marginal part of an air bag cover 1 of a designed surface side (front side) is formed. Thereafter, a resin interface 7 on a resin connecting part of a resin to constitute the air bag cover part 1 and a resin to constitute the non-air bag cover part 2 is formed so that its one end makes contact with a wall of the groove type recessed part 5 and crosses a base material in the thickness direction. Consequently, even when resin connecting strength is properly lowered, proper strength is normally maintained, and at the time when an air-bag bag body is unfolded and expanded by receiving impact, the air-bag bag body is ruptured from the resin interface 7.

摘要： PURPOSE:To obtain a laminated formed body, which is excellent in cleanability and lightweight properties, and recyclable and favorable in soft touch by a method wherein laminating skin material having the specified friction resistance is employed onto the surface of thermoplastic elastomer layer, which is lined by resin foam and has the specified tensile characteristics. CONSTITUTION:Layer made of thermoplastic elastomer, the 100% modulus of which at 23 deg.C is 10-55kg/cm , is lined by resin foam layer. In addition, by applying coating material onto the surface of the elastomer layer, laminating skin layer 5, which has the friction resistance (tan delta) between the surface of the elastomer layer and metal surface of less than 0.8, is obtained. Under the condition that the laminating skin layer 5 is arranged between un-closed female and lame molds 1 and 2, molten thermoplastic resin 6 or pre-heated thermoplastic resin sheet is supplied between the foam layer and the female mold 1 or male mold 2. After that, by closing the female and male molds 1 and 2, the skin material and the thermoplastic resin are laminated together. Thus, the laminated formed body, which is excellent in cleanability, lightweight properties and recycling properties and favorable in soft touch, is obtained.
