PROBLEM TO BE SOLVED: To enable the producing of resin molding with a good specular or an embossed face in a comparatively simpler process and in a comparatively shorter cycle time. SOLUTION: This pressure control device comprises pressure regulation mechanisms 72, 71, 70, 76, 77 for regulating the pressure of a fluid which is guided into and/or guided out of a space B on the back face side of the molding face of a mold body 3 and a control means for controlling the pressure regulation mechanisms 72, 71, 70, 76, 77 so that the pressure of the fluid to be guided into and/or guided out of the space B is balanced with a pressure to press a thermoplastic resin P to the molding face. |
