摘要： An hydraulic control circuit for an injection molding machine feedback-controls the operations of an injection cylinder by connecting an hydraulic source and an oil tank to a hydraulic actuator through a plurality of servo valves. The plurality of servo valves, such as four-port servo valves, are connected in parallel and a servo valve control function unit is used which controls the servo valves preferentially to the feedback control to permit series or parallel control of the servo valves. Thus, even when the specifications of an injection molding machine require a larger size and higher speed, the size of the injection molding machine is prevented from increasing, the cost is decreased, the response speed and the stability are remarkably improved, and fine control is realized over a wide control range.

摘要： A first direction shifting valve adapted to supply pressurized hydraulic oil to a hydraulic chamber on the rearward displacement side and discharge hydraulic oil from the hydraulic chamber on the rearward displacement side, and moreover, discharge hydraulic oil from a hydraulic chamber on the forward displacement side is disposed in a hydraulic path extending between a hydraulic pump and an injection cylinder. In addition, a second direction shifting valve adapted to supply pressurized hydraulic oil to a chamber on the forward displacement side is disposed in the foregoing hydraulic path. Additionally, a third direction shifting valve is disposed to build a bleeding-off circuit in cooperation with the second direction shifting valve. While a hydraulic path on the rearward displacement side is blocked by the third direction shifting valve, a hydraulic path on the forward displacement side is hydraulically connected to the tank side. When the third direction shifting valve is shifted to the opposite side so that the hydraulic path on the rearward displacement side is hydraulically connected to the tank side and the hydraulic path on the forward displacement side is blocked by the third direction shifting valve, an injection molding operation can be started. With such construction, a rising time of each injection molding operation can be shortened while pressurized hydraulic oil is preliminarily exerted on the hydraulic chamber on the forward displacement side under the bleeding-off condition.
摘要翻译： 第一方向移动阀，其适于向后方排出侧的液压室供给加压液压油，并且从后方排出侧的液压室排出液压油，而且从前方排出侧的液压室排出液压油， 设置在在液压泵和注射缸之间延伸的液压路径中。 此外，适于向前移位侧的室供给加压液压油的第二方向移动阀设置在前述液压路径中。 此外，第三方向移动阀被设置成与第二方向移动阀协作建立排出回路。 当向后移位侧的液压路径被第三方向移动阀阻挡时，前移位侧的液压路径液压地连接到油箱侧。 当第三方向换向阀向相反侧移动时，使得向后移位侧的液压路径液压连接到油箱侧，并且向前排量侧的液压路径被第三方向换档阀阻挡时，注射成型 可以开始操作。 通过这样的结构，可以缩短每个注射成型操作的上升时间，同时在排气条件下，在向前排出侧的液压室上预先施加加压液压油。

摘要： A method of operation for an injection molding machine is disclosed. The injection molding machine includes an injector having an advancable screw and a barrel cylinder, and a mold clamp for holding a mold with a controllable pressure and for allowing the mold to open a controllable amount. In performing the method, preset values are established for a stop position of the advancable screw, a clamping pressure of the mold clamp, and an opening amount for the mold. The screw is advanced up to the preset stop position and stopped thereat. The screw is controlled so as to ensure the location of the screw at the preset stop position for a preset time. Resin is injected from the barrel cylinder into the mold. The mold is clamped with the preset clamping pressure, during the preset time, by operating the mold clamp while maintaining the positioning of the screw at the preset stop position. Further, the mold clamp is operated to controllably allow for opening of the mold during the injecting step, so that the mold is allowed to open to the preset opening amount when the injecting step is completed.
