物の製造装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a synthetic resin foam molded product having an uneven shape, which is formed by integrally bonding a skin material such as a vehicle interior decorative panel or a door panel.
表面に凹凸形状を有する合成樹脂発泡体成形物に装飾用

状に賦型するとともに表皮材を発泡層と一体に結合させ
るものであった。Molded products, in which a decorative cover or the like is attached to a synthetic resin foam molded product with an uneven surface, are widely used in various fields. Conventionally, the method for manufacturing the above molded products is A skin material is added to the inside of the mold in advance, then a stock solution for foam formation is injected into the mold, and the mold is closed before the stock solution foams and overflows from the mold. In this method, the pressure of the polymerization reaction of the foaming stock solution was used to shape the foam into a certain shape that followed the shape of the mold, and at the same time, the skin material was integrally bonded to the foam layer.
したがって、金型および金型の移動装置を含む成形装置
は発泡原液の重合圧力に耐える構造を必要とし、設備が
大型化して設備費が高価になるという問題点があった。Therefore, the molding apparatus including the mold and the mold moving device needs to have a structure that can withstand the polymerization pressure of the foaming stock solution, resulting in a problem that the equipment becomes large and the equipment cost increases.
そこで、合成樹脂発泡成形戒用原液を自然発泡させ、そ

る。(7) Molding pressure o, i ~ 1k19/7 As described above, in the present invention, the foam layer a and the skin material 5 are formed in the formwork 2.
The step of laminating the materials to form a raw material is carried out on the rotary table 1, and then this raw material is transferred into the mold 14 on the rotary table 13 for pressurization, mold clamping and aging,
A molded article M shaped into a predetermined shape is obtained, and by regulating the rotational speed of each rotary table 1.degree. 13, a uniform molded article shaped into a fixed shape can be continuously obtained.

製造を行なうことができる効果を有するものである。In the present invention, since the stock solution is pressurized and molded in the mold 14 after spontaneously foaming, the polymerization pressure of the foaming stock solution is not applied to the mold 14, and the structure of the mold is simplified and compact equipment is required. This has the effect of automating the work process and efficiently producing synthetic resin foam molded products.
