PROBLEM TO BE SOLVED: To make it unnecessary to adjust the length of a nozzle for injecting a molten resin into the injection part of a mold device for injection molding. SOLUTION: An embedded nozzle part 43 is set in the injection part 21, and the molten resin injected from the nozzle 11 into the injection part 21, is supplied to a communication part 26 after being passed through the nozzle part 43. A contact part 33 which can come into contact the nozzle 11 entering the injection part 21 and a nozzle touch part 32 having a sub-shut-off 34 which can close the nozzle part 43 are arranged. When the contact part 33 is not pressed by the nozzle 11, the nozzle part 43 is closed by the sub-shut-off 34. When the contact part 33 is pressed by the nozzle 11, since the sub-shut-off 34 is moved, the nozzle part 43 is released. COPYRIGHT: (C)2005,JPO&NCIPI
