2. Description of the Related Art Conventionally, when a headrest of a vehicle equipment seat is manufactured as a foam-integrated foamed product, a headrest frame continuously assembled with a headrest stay is sewn into a hollow three-dimensional shape (hereinafter referred to as a "headrest cover"). ), A long slit-shaped opening extending in the width direction of the headrest cover is provided on the bottom surface of the headrest cover. In addition, this opening is used to insert a resin injection nozzle to foam a cushion layer (hereinafter referred to as a “cushion pad”) inside the headrest cover, and to fill the inside of the headrest cover with the foamed resin. It is also used as an entrance.

When the opening of the headrest cover is used as an injection port for foamed resin, the resin injection nozzle may be pulled out from the opening of the headrest cover after filling with the resin, or may be left inserted without being pulled out. . Among them, when extracting the resin injection nozzle, there is a possibility that the foamed resin leaks from the nozzle tip during extraction of the resin injection nozzle and stains the headrest cover. In addition, if it is inserted without being extracted, nozzle marks will remain on the product.

Further, when the above-mentioned slit-shaped opening is provided, an opposing sealing margin is folded back inside the headrest cover, and the sealing margin is pressed closely together by foam cushion pads. Sealing the opening is performed. However, if the cushion pad is merely foamed inside the headrest cover, the internal space or the shape of the headrest cover is different through the sealing allowance, so that the foaming condition of the foamed resin until each sealing allowance is reached. Are different from each other, the sealing margin is biased to one side and pressed by the foamed resin, so that a situation occurs in which the opening is deformed.

As described above, according to the apparatus for molding a skin-integrated foamed product according to the first aspect of the present invention, the resin injection nozzle is kept open by keeping the opening of the skin open by the opening plate. The foamed resin is filled by inserting it into the inside of the housing, and after filling the foamed resin, the resin injection nozzle is extracted from the inside of the skin, so the foamed resin leaks during the extraction from the insertion of the resin injection nozzle. Even if it falls, it can be prevented from adhering not only on the surface side of the skin but also around the edge of the opening, thereby reliably preventing the skin from being stained.

According to the apparatus for molding a skin-integrated foamed product according to the second aspect of the present invention, the receiving plate is located between the opening of the headrest cover and the mouth during the foaming of the foamed resin. The opening part regulates the position of the sealing allowance with the receiving plate even if the foaming condition up to each sealing allowance of the foamed resin is different due to the difference in the inner space or the shape of the skin through the sealing allowance, The opening can be prevented from being deformed due to the sealing margin being biased to one side and pressed by the foamed resin, and the opening in the skin can be tightly sealed and beautifully sealed.
