    摘要： A temperature adjustment mechanism for use in an injection molding machine that shortens a molding cycle time while preventing the occurrence of a stranding phenomenon in an optimum manner. A passage includes an opening arranged near an outer surface of an outlet of an injection nozzle for an injection molding machine. A supply control unit supplies the passage with at least one of cooling air and heating air to selectively eject the cooling medium, the heating medium, and a mixture of the cooling medium and the heating medium near the outer surface of the outlet.

    摘要： A resin flow analysis in a die is performed by CAE or the like to obtain a resin pressure curve at a resin inlet port or a resin pressure curve at a nozzle end portion of a molding machine. Injection (air shot) is performed while a nozzle is separated from a die, so that an injection pressure curve Pa to be detected at this time is obtained. From the injection pressure curve and the resin pressure curve, an injection pressure command curve serving as a molding condition in mass production is obtained. The resin pressure curve obtained by the resin flow analysis is compensated by the injection pressure curve in an air shot for a time lag and pressure loss caused by the mechanical elements of an injection molding machine, so that molding conditions in mass production can be easily obtained. In addition, a pressure loss at the nozzle portion is also obtained, so that an injection pressure command curve is obtained from the pressure loss, the injection pressure curve, and the resin pressure curve.

    摘要翻译： 通过CAE等进行模具中的树脂流动分析，得到树脂入口处的树脂压力曲线或成型机的喷嘴端部的树脂压力曲线。 在将喷嘴与模具分离的同时进行喷射（空气喷射），从而获得此时要检测的喷射压力曲线Pa。 根据注射压力曲线和树脂压力曲线，获得用于批量生产的成型条件的注射压力指令曲线。 通过树脂流动分析获得的树脂压力曲线通过喷射压力曲线在喷射时间延迟和由注塑机的机械元件引起的压力损失的情况下进行补偿，从而可以容易地获得批量生产中的成型条件 。 此外，还获得喷嘴部分处的压力损失，从压力损失，喷射压力曲线和树脂压力曲线获得喷射压力指令曲线。
