ウレタンを注入して一体成形する方法が主流であった。2. Description of the Related Art As a method for producing a resin molded article such as an instrument panel, a door rim, a console box, etc., which is an interior part of an automobile, a blended resin of vinyl chloride and ABS resin is extruded into a sheet shape, and then an etching squeezing roll is used. After a pattern is placed, the skin material shaped by vacuum molding and the core material (base material) shaped by injection molding or stamping molding are placed in a urethane foam mold, and then urethane foam is injected to integrally mold the material. The method was the mainstream.

ための発泡成形には、コストがかかり過ぎると言う評価
もあった。The problem with this method is that it does not give a sufficient feeling of skin drawing due to etching and that the drawing is enlarged and shallowed by stretching the sheet by vacuum forming. Further, when considering recycling of parts, there is a problem that the above-mentioned three-layer structure cannot be easily separated, and the cost of waste disposal increases. Furthermore, since the above-mentioned construction method comprises three steps, that is, skin molding, core material molding, and foam molding, it has been evaluated that the foam molding for obtaining a soft feeling of the product is too costly.

Injection press molding method or SP mold (Low S
What is called a "Train Molding Process" is adopted. This is a composite sheet lined with EPP on a calendered or extruded sheet by vacuum forming, set in a female die of an injection molding die, and supplying molten resin into the die during the die clamping operation. The skin material and the core material are integrally molded by pressing pressure.

The integrally foamed product of the core has been adopted as a product having an excellent squeezing feeling.

むら等の外観不良が発生する。However, one of the drawbacks of the SP molding method among the above-mentioned molding methods is that the exposed portion of the resin is large in the partially bonded portion of the skin material, or
When the product shape is complicated and there is a portion where the molten resin is difficult to rotate, it is necessary to set the gate at an appropriate position, but in that case usually there is a ring mark around the gate or defective appearance such as gloss unevenness. Occur.

招く。Further, as the mold structure, since the resin is supplied before the mold is clamped, in order to set the through hole (opening) in the product at the time of molding, the resin flowing into the through hole is sealed before the mold is clamped. In order to do so, it is necessary to install a special insert, which is required for all openings including mounting holes. Further, even in the resin exposed portion where the skin is not adhered, a cutout shape is required on the outer periphery similarly to the skin adhered portion, which causes an increase in mold cost.
