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： A process and apparatus for effecting injection molding of plastic resin products on an injection molding apparatus including a metal mold composed of a slidable mold element and a fixed mold element defining together the mold cavity, an actuator for sliding the slidable mold element and an injection nozzle for adjusting the nozzle flow path section, which comprises a first molding step of injecting a molten resin into the mold cavity which has been preset by the slidable mold element so as to include a post-compression margin to be compressed afterwards in a second molding step, to effect the injection under a reduced molding pressure, while causing a temperature elevation and, thus, a viscosity reduction of the molten resin, until the mold cavity has been filled up, and a second molding step of compressing the resin so charged in the mold cavity by operating the slidable mold element to compress the charged resin to compensate the post-compression margin, so as to allow an effective pressing force to be imposed onto the charged resin within the mold cavity also after the gate has been sealed.
