摘要：
A device for and method of molding for an injection molding machine, by which fluctuation in weight of an injection-molded resin product is reduced to stabilize its quality. For satisfying the purpose, a screw (61) of an injection unit (30) is moved forward to start injection of molten resin when the upper metallic mold (15) reaches a specified position, decelerated to a specified speed when advanced to a fixed position, and stopped when it reaches a predetermined stop position; and molten resin is reduced in injection flow quantity and pressurized until the gate (71) is closed.
