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.

摘要： The resin injection molding method of the present invention is a method for molding resins inside a cavity formed within a mold. The method comprises injecting resins into the cavity through a plurality of paths installed so as to be openable and closable and optionally maintaining the resin inside the cavity at a pressure; closing each of the plurality of paths such that the resins injected from each path converge, there being a time difference between when a first path and a second path of the plurality of paths are closed; and solidifying at least the resin which is injected from the path closed earliest with a crystallinity greater than or equal to a predetermined crystallinity degree.
