A spring structural resin molded product capable of eliminating the peeling of the fused part of the spring structure resin molded product by uniformly distributing cooling water throughout the entire surface of a chute to eliminate the overcooling and insufficient cooling of a three-dimensional structure by the cooling water and deeply drawing the width of the melting and continuous three-dimensional structure, and a device and a method for forming a surface layer on the spring structure resin molded product. The cooling water (C) is fed between a water permeable sheet (55) and a sloped plate (51a) to penetrate the cooling water (C) into the upper surface of the water permeable sheet (55) so as to form a cooling water upper layer (M). The three- dimensional structure (3) is supported on the cooling water layer (M) to form the surface layer so as to adjoin continuous adjacent lines with each other.

L'invention concerne un produit moulé en résine à ressort structurel, qui permet d'éliminer le pelage de la partie fusionnée du produit moulé en résine à ressort structurel grâce à une distribution uniforme de l'eau de refroidissement sur la totalité de la surface d'une goulotte de manière à empêcher le refroidissement excessif ou insuffisant par l'eau de refroidissement d'une structure tridimensionnelle; en outre, on parvient à étirer fortement la largeur de la partie fusionnée et de la structure tridimensionnelle continue. L'invention concerne aussi un dispositif et un procédé pour former une couche de structure sur le produit moulé en résine à ressort structurel. On alimente l'eau de refroidissement (C) entre une feuille perméable à l'eau (55) et une plaque inclinée (51a), de manière à permettre à l'eau de refroidissement (C) de pénétrer à la surface supérieure de la feuille perméable à l'eau (55) et de former ainsi une couche supérieure d'eau de refroidissement (M). La structure tridimensionnelle (3) repose sur la couche d'eau de refroidissement (M) de manière à former la couche de surface et à connecter entre elles les lignes adjacentes continues.
