摘要： A protecting apparatus of an injection molding machine having an injection of cylinder 2r with a built-in double rod type piston, and a servo valve for driving and controlling the injection cylinder includes a power failure detecting circuit for detecting a power failure, and a power-failure-time signal outputting circuit Ub for outputting a neutral signal, by which the servo valve is controlled at a neutral signal, by which the servo valve is controlled at a neutral position, to an instruction signal input line for the servo valve, due to the detection of the power failure by the power failure detecting circuit. A power-failure-time shutting down circuit is connection to the oil transferring line for supplying pressurized oil to the injection cylinder. The power-failure-time shutting down circuit includes a control valve for opening the oil transferring at the time of the non-power failure, and for shutting down the oil transferring line at the time of the power failure. Thereby, even if the power failure occurs in the state when the purging cover is closed at a time of positional control in the unguarded state a problem where the resin is ejected at high speed can be presented.

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： 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 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.

摘要： An injection molding apparatus of a metal material places a heating cylinder in an inclined position. The heating cylinder includes a nozzle at a tip thereof and a screw disposed inside. In this way, the metal material in a liquid phase state can be transferred and metered accurately in a reliable manner at all times by flowing due to the inclination and a transfer force produced by rotation of the screw. A clamping apparatus is provided to oppose the injection apparatus and includes a mold having a sprue bush inside. The injection apparatus and the clamping apparatus are placed on an apparatus platform in an inclined position at the same angle with the mold in a lower end, so that the metal material in the liquid phase state in the heating cylinder flows down toward the head due to self-weight. The nozzle and sprue bush are positioned on the same straight line, thereby maintaining nozzle touch without bending the nozzle.
