摘要： A method for taking countermeasures against faulty molding in which, with the aid of an expert system, restoration to a nondefective molding condition when faulty molding takes place during the mass production of molded products. When threshold values of a plurality of molding parameters, and information indicative of countermeasure processes, respectively corresponding to combinations of evaluations on these parameters and determined on the basis of the knowledge and experiences of skilled persons, are manually entered through a data input device (119), they are stored in tables of a memory (110) beforehand under the control of a processor (114). Upon start of the mass production, the injection time, metering time and cushion amount which are measured or calculated during a molding cycle, and the resin pressures corresponding to the manually set screw positions at the time of passing the gate and filling are set in the tables as reference values of the parameters. Upon occurrence of faulty molding, the processor makes an evaluation on each parameter by comparing the deviation between each parameter value in the molding cycle accompanied with the faulty molding and its reference value with threshold values, and changes desired ones of parameter values forming the molding condition, in accordance with a countermeasure process that has been read from the tables in dependence on results of the evaluations.

摘要： A discrimination method for maintenance timing for injection molding machines, detects the respective values of molding process parameters of a plurality of types, including injection time, maximum injection pressure, etc., for each of the injection molding machines (7-1 to 7-M). Up-to-date process parameter values for the molding machine are entered as a set of monitor data in a molding monitor unit (1) every time a predetermined number of molding cycles are executed in each molding machine. A plurality of monitor data values for each type are read, on a time-series basis, from a memory (4) loaded with a plurality of sets of up-to-date monitor data values associated with each molding machine, by means of a microprocessor (2), and dot-line data are generated. Based on an approximate equation of the first degree indicative of the transition trend of each type of monitor data obtained using the dot-line data, an estimated value of the monitor data for a point in time after the present point of time is calculated. A warning message to demand the maintenance of an expendable part of the injection molding machine associated with the monitor data is displayed on the screen of a display unit (6) when it is concluded that the estimated value deviates from an allowable range for the monitor data. Thus, maintenance timing for the injection molding machine can be confirmed without disassembling the injection molding machine.

摘要： A molding condition recording apparatus having a manual data input device with a CRT. The manual data input device has various keys for inputting parameters of various groups used for controlling injection, hold, metering and cylinder temperature, and for inputting molding defect indication data. A microprocessor for a programmable machine controller causes the input parameters and the molding defect indication data to be stored in a molding condition storage region of a shared memory (S5). The microprocessor then discriminates similarity between the thus stored molding condition and the molding condition already registered in a molding condition/molding defect storage file of a memory other than the shared memory (S7). If there is similarity between these molding conditions, the microprocessor causes the CRT to display an alarm message thereon together with the parameter already registered in the file and the mold defect indication data (S12). When there is no similarity between the molding conditions, the microprocessor transfers the molding condition stored in the shared memory to the file for storage therein. Even when the alarm message is displayed, a similar transfer and storage process is carried out if it is requested by an operator (S 13).

摘要： A product acceptance/rejection judgment method which always ensures accurate judgment whether a product is acceptable or not even when an injection molding machine is operated in different operating environments is implemented by a processor (22) of a numerically controlled device (20). When the processor determines that it should perform, in addition to a normal product acceptance/rejection judgment based on molding process parameters, an auxiliary product acceptance/rejection judgment based on at least one operating parameter which directly indicates an injection molding machine operating environment characteristic involved in the acceptance/rejection judgment of the product, the processor reads output data from an A-D converter (11, 12 or 13) which data corresponds to the actual value of at least one operating parameter detected by an appropriate die temperature sensor (8), open air temperature sensor (9) or a wind velocity sensor (10). If an actual value of any one of the operating parameters deviates from the tolerance limit, and the processor determines that a molding failure may have occurred, the processor issues a failure signal. If all actual values of at least one operating parameter are within the tolerance limits, then the normal product acceptance/rejection judgment process is further implemented.

摘要： During a mold thickness adjustment process of an injection molding machine, a mold touch position at which the mold halves of a mold contact each other is detected, and the mold temperature is detected by means of thermocouples attached to the mold halves, respectively. Also, the mold thickness is obtained based on the position where a movable platen and a stationary platen of the injection molding machine contact each other, which is obtained previously, and the detected mold touch position.After a molding operation is started, the mold temperature (Tn1, Tn2) is detected in each of molding cycles, and the amount of change of the mold thickness (.DELTA.e) during the period between the preceding cycle and the current cycle is calculated (S14) based on the change of mold tempreature (.DELTA.T) during the period between the two cycles, the mold thickness (e), and the thermal expansion coefficient (k). The mold touch position for the current cycle (P) is obtained (S16) based on the calculated value. When the mold is clamped in the current cycle, the movable platen is moved from the mold touch position toward the stationary platen by a predetermined amount, to produce a predetermined mold clamping force.

摘要： A drive system abnormality detecting apparatus of an injection-molding machine includes a microprocessor (19) for a controller, which causes a display unit (24) to indicate the occurrence of an abnormal situation. The drive of a servomotor (5) for an injection is stopped when the microprocessor concludes that the difference between the driving current of the servomotor and the output of a force detector, indicative of the resin pressure inside a cylinder (2), is not within predetermined permissible limits. The motor driving current and the detector output are individually periodically detected, during the time interval between the start of injection to the end of metering. By doing th is, the microprocessor prevents production of defective moldings, attributable to the occurrence of an abnormal situation in a screw drive system, and damage to components of the screw drive system and dies.

摘要： An injection control method for an electrically-operated injection molding machine is provided, which is capable of sharply increasing the injection speed of a low-priced electric injection molding machine. A command pulse train is supplied to a servo circuit for an injection servomotor whereby substantial rotary motion of the injection servomotor is initially prevented, as a result of the fact that the torque limit value (Ts) is set at a value sufficient to establish equilibrium between the output torque of the injection servomotor and the resin pressure acting on the injection screw. The error between the target rotational position of the injection servomotor and an actual rotational position thereof then is allowed to increase until it reaches a feed stop positional error (Fs). The torque restriction is discontinued when the feed stop positional error Fs is reached, and a large drive current is caused to flow in the injection servomotor circuit in correspondence with the actual positional error which has now increased to the feed stop positional error Fs. Thus, the injection screw is initially driven by a great torque generated by the injection servomotor, so that the injection speed rises sharply.

摘要： A positioning correction method for a motor-operated injection molding machine, intended to eliminate waste of power supply to or overheat of servomotors by locking up in an ideal state the motor-operated injection molding machine, which uses a toggle mechanism or crank for mold clamping and other operations. During the lockup period, a load RA acting on a mold clamping servomotor 7 is detected (S8), and a position command value PM for the servomotor 7 is increased or decreased in the next cycle in a direction such that the value of the load RA is reduced, if the value of the load RA is greater than a preset reference value V0 (S12, S13). As a result, a rotation center Q1 of a crank 2 and two opposite ends Q2 of a link 3 are locked up in a straight line, so that a moment of rotation produced by a mold clamping reaction force is removed from the rotation center Q1 of the crank 2. In this manner, the mold clamping reaction force can be maintained during the lockup period without applying a driving torque to the mold clamping servomotor 7 by energizing the same. Thus, not only the waste of power can be prevented but also the load on the mold clamping servomotor 7 can be reduced, thereby unnecessitating the use of a stopper or other means for maintaining the mold clamping reaction force.
