PURPOSE:To prevent the generation of defective molding by loading an insert part in a cavity, feeding an insert supporting component therein to support the insert part, injecting resin into the cavity and feeding out the part supporting component when the pressure in the cavity reaches the set value. CONSTITUTION:A molded part 6 is loaded in a cavity 3 in the state that a top force 1 and a bottom force 2 are opened. A core pin 7 is fed into the cavity 3 by actuating an actuator 8, and the molded part 6 is pressed downward and resin is injected from a runner 5 into the cavity 3. When the pressure in the cavity 3 is raised beyong the set value, a set pressure access signal is issued from a pressure sensor 10 to a control device 9, and the actuator 8 is started to work and the core pin 7 is fed out of the cavity 3. The resin is filled in a site where the core pin 7 was, and then the resin is heated (cooled) and cured to complete the resin molding. |
