Abstract: The invention relates to an injector unit and a method for the control of the injection process into the cavities of injection moulding tools. The novel solution permits the injection of thin-walled injection moulding pieces (76, 77), with both electrically- and hydraulically-driven injector screws. One of the most important features thereof is the active selection of the opening time of the locking system at an optimal pressure in the compression chamber, preferably in the region of the upper half of the compression. The volumetric transfer flow is thus significantly improved in thin-walled injection moulding pieces (76, 77). Above all the melting pressure in the tool, the flow speed and the useful flow path in the cavities are increased.

Abstract: A method of controlling an injection molding machine by use of nozzle resin pressures in which resin is directly controlled to thereby enable highly accurate control, and a conventional mold can be utilized as it is.
After metering a dose of resin, a resin pressure at the upstream side of a nozzle switching valve (12) is detected while the nozzle switching valve (12) is kept closed, and a pre-load is applied on the resin by controlling an injection cylinder (19). Subsequently, the nozzle switching valve (12) is opened, and injection of the resin is performed, then applying a dwell pressure on the resin in the mold. During the injection and dwell pressure application steps, a resin pressure at the downstream side of the nozzle switching valve (12) is detected, and the injection cylinder (19) and the nozzle switching valve (12) are controlled. In these steps, the resin to be filled is directly controlled, and therefore, the control can be carried out highly accurately. After the dwell pressure application step, the nozzle switching valve (12) is closed. Then, the resin pressure at the upstream side of the nozzle switching valve (12) is detected, and a back pressure is applied on the resin at the front end of a screw feeder (2) by controlling the injection cylinder (19).Abstract translation: 通过使用直接控制树脂的喷嘴树脂压力来控制注射成型机的方法，从而能够进行高精度的控制，并且可以直接利用传统的模具。 在计量一定剂量的树脂后，在喷嘴切换阀（12）保持关闭的同时检测喷嘴切换阀（12）的上游侧的树脂压力，并且通过控制喷射将预加载到树脂上 气缸（19）。 随后，打开喷嘴切换阀（12），进行树脂的注入，然后对模具中的树脂施加停留压力。 在注射和停留压力施加步骤期间，检测喷嘴切换阀（12）的下游侧的树脂压力，并且控制注射缸（19）和喷嘴切换阀（12）。 在这些步骤中，要直接控制要填充的树脂，因此可以高精度地进行控制。 在停留压力施加步骤之后，喷嘴切换阀（12）关闭。 然后，检测喷嘴切换阀（12）的上游侧的树脂压力，通过控制注射缸（19）对螺杆给料器（2）前端的树脂施加背压。
