Abstract: When a determination condition is set for determining whether a molded product is non-defective or defective, a molding operation is performed a predetermined number of times. In each molding operation, an actual value of at least one monitor item which can serve as the basis for determining whether a molded product is non-defective or defective is detected. The detected actual values are displayed on a screen of a display in such a manner that a distribution of the actual values can be visually grasped. A sampling zone for the displayed actual values is designated in such a manner that a portion of the displayed actual values are contained in the sampling zone. The determination condition is automatically set on the basis of actual values contained in the sampling zone.

Abstract: An electromechanical clamping device with hydraulic assistance is described. A thrust mechanism driven by an electric motor displaces two clamping jaws with respect to each other along a guide device. One clamping jaw is divided into two mutually displaceable part jaws. A chamber to hold pressure medium is formed between the part jaws. The first part jaw can be displaced along the guide device and locked with respect to the latter. One part jaw is provided with a first cylinder coupled to the output of the thrust mechanism. In order to close the clamping device, in a first step the thrust mechanism pulls the part jaws against the other clamping jaw, in a second step the thrust mechanism delivers pressure medium from the first cylinder into the chamber between the two part jaws, with the first part jaw locked with respect to the guide device. To open the clamping device, in a first step a second cylinder arranged between the two part jaws pulls the part jaws against each other, with the first part jaw locked with respect to the guide device, and then in a second step the thrust mechanism forces the part jaw coupled to it in the opening direction, forcing the other part jaw with it, with the first part jaw unlocked from the guide device. The clamping device is provided for production machines, in particular for injection molding machines.

Abstract: The present invention replaces the multiple controller systems by incorporating the controller of sensory devices with the part-forming machine controller (typically a personal computer), thereby producing a synergistic combination. More specifically, sensory devices such as, for exemplary purposes only, cameras, infrared sensors, ultrasonic sensors, or other sensing devices are connected directly to one or more preexisting serial, parallel or USB ports or other bus interfaces of the machine controller. By programming the machine controller or loading software therein, the machine controller can receive the input signal(s)/data from the sensory device, analyze the data, provide an output signal to the sensory device and communicate directly and contemporaneously with the machine controller software.

Abstract: A disturbance estimating observer is provided, which estimates a load applied to a servomotor for driving an ejector axis. When an ejector operates, the disturbance load torque estimated by the observer is sampled for each specific period (0 to j), and the data DA (0, 0) to DA (i, j) of (i+1) ejector processes are stored in a table TA in the form of cyclic storage. From this table TA, average values DB (0) to DB (j) of estimated disturbance load torques are determined in turn and they are stored in a table TB. From these average values, upper limit values DC (0) to DC (j) and lower limit values DD (0) to DD (j) of a permissible range are stored in tables TC, TD. When the determined estimated disturbance load torque has exceeded the permissible range, an abnormal load signal is outputted.

Abstract: An injection molding apparatus and method are provided in which the rate of material flow during an injection cycle is controlled. According to one preferred embodiment, an injection molding apparatus is provided that includes a manifold, at least one injection nozzle coupled to the manifold, an actuator, and a valve pin adapted to reciprocate through the manifold and the injection nozzle. The valve pin has a first end coupled to the actuator, a second end that closes the gate in a forward position, and a control surface intermediate said first and second ends for adjusting the rate of material flow during an injection cycle. Retracting the valve pin tends to decrease the rate of material flow during the injection cycle and displacing the valve pin toward the gate tends to increase the rate of material flow during the injection cycle.

Abstract: A method and an apparatus are disclosed for controlling a motional sequence of a first movable component of a plastic material injection molding machine having a first trajectory spatially overlapping at least partially a second trajectory of a second movable component of the plastic material injection molding machine. Motion of the first movable component is initiated depending on an enabling signal indicative for a motional state of the second movable component. The method comprises the steps of: a) determining a first period of time (TWA; TRE) between a first moment in time (tFW; tFR) when the enabling signal is generated and a second moment in time (t6; t3) when the first movable component enters the second trajectory; b) determining a second period of time (TRAmax; TWEmax) between the first moment in time (tFW; tFR) and a third moment in time (t10; t8) when the second movable component leaves the first trajectory; c) comparing the first period of time (TWA; TRE) with the second period of time (TRAmax; TWEmax) and generating a difference signal therebetween; and d) controlling motion of the first movable component as a function of this comparison of the first period of time (TWA; TRE) with the second period of time (TRAmax; TWEmax) such that the difference signal is smaller than a predetermined minimum tolerance value (T2; T1).

Abstract: An injection is carried out under a certain molding condition with a nozzle in an injection molding machine left open to sample an injection pressure Pr in every certain cycle for storing. Detected pressure data Pr(0) to Pr(N) for one shot is stored as reference pressure data Pr0(0) to Pr0(N). When defective molding occurs or when a resin lot is changed or the like, the injection is carried out with the nozzle left open under the same molding condition as that used in obtaining the reference pressure data and obtain the detected pressure data Pr(0) to Pr(N). Waveforms of the detected pressure data Pr(0) to Pr(N) and reference pressure data Pr0(0) to Pr0(N) are graphically represented so that variation of the molding condition is observed. It is assumed that if there are any differences, a problem presumably resides in resin, while if there is no difference but the defective molding occurs, the problem presumably resides in a mold.
