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： There are provided an injection molding system, a computer program, a method of injection molding, and an injection molding machine capable of performing precise temperature control of a mold even when there is a delay in temperature increase of the mold in heat supply with a heating medium. The temperature control is performed so that temperatures of a fixed mold and a movable mold are maintained between an upper limit TU and a lower limit TL of a predetermined temperature range after start of injection of resin during an injection molding cycle. The temperature control of the fixed mold and the movable mold is performed only by switching ON/OFF supply of the heating medium, and cooling with a cooling medium is not performed. In a process of cooling the resin, the temperature control is performed so that the temperatures of the fixed mold and the movable mold are maintained between an upper limit TUa and a lower limit TLa of a temperature range effective for resin annealing by stop of supply of the cooling medium and the supply and stop of the heating medium.

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.
