    摘要： It is an object to prevent dies from interfering with each other when the dies are closed and effectively prevent overshoot of cavity temperature while efficiently performing heating of the dies. In an injection molding machine for two-material molding including two sets of a first injecting unit and a second injecting unit that respectively plasticize different resin materials and inject and fill the resin materials, prior to performing injection molding on the first injecting unit side on a secondary side, after injection molding on the second injecting unit side on a primary side, heating of the dies is started before 180-degree rotation of a rotary die plate is completed. After the start of heating, until the 180-degree rotation of the rotary die plate is completed, i.e., die closing is performed, die temperatures are maintained within a temperature range set higher than die temperatures during the heating start and lower than die temperatures during injection.
