PROBLEM TO BE SOLVED: To prevent entrainment of air between a molten resin and the mold in a resin molding apparatus which discharges a molten resin on a mold through a T die by the use of an injection apparatus equipped with a T die at the discharge outlet and clamps to mold a resin product. SOLUTION: A gutter-shaped member 4 for receiving a molten resin 1 discharged from a T die 3 and flowing it onto the mold 5 is arranged below the T die 3, and the bottom surface of the gutter-shaped member 4 is inclined so that the central part is lower than peripheral edge parts with respect to the flow of the molten resin 1 in the vertical cross-section. In this example, the cross-section of the bottom surface of the gutter-shaped member 4 is V-shaped. COPYRIGHT: (C)2007,JPO&INPIT
