PROBLEM TO BE SOLVED: To provide an injection molding method and an injection molding die allowing a molded product molded in a first die and a second die by injecting material, to be surely taken out of the second die side. SOLUTION: This die molding method is carried out by allowing a fixed die 10 and a movable die 40 to abut on each other to form a cavity 2, bringing the molded product 92 into close contact with the movable die 40 when separating the movable die 40 from the fixed die 10 after injection-molding a molding material MT, and then separating the molded product 92 from the movable die 40 using an eject pin 50. When the movable die 40 is separated from the fixed die 10, a push-out means 30 provided at the fixed die 10 pushes out the molded product 92 toward the movable die 40 side, and mold release resistance force R when the eject pin 50 separates the molded product 92 from the movable die 40 is measured by a load cell 70. The push-out force F of the push-out means 30 is changed according to the mold release resistance force R measured by the load cell 70. COPYRIGHT: (C)2009,JPO&INPIT
