<P>PROBLEM TO BE SOLVED: To precisely control the temperature of a molding material injected into the mold from a flow passage of a nozzle by easily changing the cross-section of the flow passage of the nozzle. <P>SOLUTION: An injection molding machine 1 is provided with the nozzle 30 having a throttle part 32 formed in the flow passage 31 and the molding material S is injected into the mold 10 through the flow passage 31 to manufacture the molding. In the injection of the molding material S, the nozzle 30 in the injection molding machine 1 is abutted to the mold 10, the distance between a flow passage adjusting member 50 arranged in the flow passage 31 and the throttle part 32 is changed to control the cross-section area of the flow passage 31 between the throttle part 32 and the flow passage adjusting member 50. In the injection molding machine 1, the molding material S is injected into the mold 10 through the flow passage 31 between the throttle part 32 and the flow passage adjusting member 50. <P>COPYRIGHT: (C)2012,JPO&INPIT |
