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： Clamping and injection operations are executed partially in parallel by adjusting a clamping speed and an injection start timing T so that sum .SIGMA.P of resin pressure acting on the parting plane of a mold cavity will not exceed mold clamping force F outputted at that time. An injection operation is started during the period in which the mold clamping force F is relatively low between mold touch and mold clamping completion, so that gas breathing from the mold cavity can be done easily without providing gas vent in the mold, thereby preventing resin filling failure or burning. Also, the clamping and injection operations are executed partially in parallel, so that time required for clamping and injection processes is shortened by time T' as a whole. Therefore, speeding of molding cycle can be attained.

摘要： A mold clamping control method capable of preventing any warp or strain on a molded product without stopping an injection pressure holding process so as to cancel the pressing force of an injection screw. In a series of injection and pressure holding processes, a movable platen is retracted from a mold clamping dwell position P2 to a mold opening dwell position P1, so that a substantial volume of a cavity of a mold is increased to temporarily lower the internal pressure of the cavity, thus making an internal stress of resin to be a product uniform to eliminate stress strains. In this method, an injection molding is performed to produce a precise product having no warp or strain even in molding a light guide plate which is subjected to molding abnormalities by the temporary stoppage of the injection pressure holding process according to the conventional method.

摘要： A method and an apparatus for automatic zero adjustment of an injection-molding machine, in which an axis driven by a servomotor can be automatically returned to its origin with accuracy and speed. When a one-revolution signal is produced after the axis reaches a deceleration position, a preset coordinate position of a reference point is written in a current-value register. Subsequently, when the axis driven toward an absolute position reaches the absolute position, the preset coordinate position of the reference point is corrected with use of a correction value calculated on the basis of a known coordinate position of the absolute position and the register value. When the axis driven toward the reference point reaches the corrected position, the preset reference point coordinate position is written in the current-value register.

摘要： An average is obtained between output readings of a pressure sensor obtained when forward and reverse thrusts are applied to an injection screw by positively driving a servomotor for injection. The average value is used as a correction value for a reading deviation of the pressure sensor. The injection servomotor is positively driven to apply a thrust to the screw. This known thrust and the actual reading of the sensor are compared. A deviation between these values is used as the correction value for the reading deviation of the sensor.

摘要： A resin flow analysis in a die is performed by CAE or the like to obtain a resin pressure curve at a resin inlet port or a resin pressure curve at a nozzle end portion of a molding machine. Injection (air shot) is performed while a nozzle is separated from a die, so that an injection pressure curve Pa to be detected at this time is obtained. From the injection pressure curve and the resin pressure curve, an injection pressure command curve serving as a molding condition in mass production is obtained. The resin pressure curve obtained by the resin flow analysis is compensated by the injection pressure curve in an air shot for a time lag and pressure loss caused by the mechanical elements of an injection molding machine, so that molding conditions in mass production can be easily obtained. In addition, a pressure loss at the nozzle portion is also obtained, so that an injection pressure command curve is obtained from the pressure loss, the injection pressure curve, and the resin pressure curve.

摘要： A zero point adjusting method and apparatus for a pressure detector of an injection molding machine, capable of carrying out a zero point adjustment of the pressure detector when external loads acting on the pressure detector are completely removed without disassembling an injection mechanism. An advance limit position Qf and a retreat limit position Qb of a screw are detected by driving the screw with a low output to determine an intermediate position Pm. By moving the screw to the intermediate position Pm, a resin reaction force acting directly on the screw is removed. Reciprocating motion in which an amplitude decreases gradually is imparted to the screw, thereby causing a backlash, having equal plays in the advance and retreat directions, between a ball nut and a ball screw. Then, the zero point adjustment of the pressure detector is made.

摘要： A temperature control method for an injection molding machine capable of performing stable temperature control at all times irrespective of the heat capacity of an object of temperature control. A temperature of an object of temperature control, such as a heating region of an injection cylinder, an injection nozzle and a mold, is detected by a respective temperature sensor G1-Gn. A feedback control of temperature is performed by a servo CPU (24) so that the detected temperature coincides with a set temperature, to obtain an electric current command value. Further, an actual electric current flowing in each of heaters H1-Hn is detected, and a feedback control of electric current is performed so that the actual current coincides with the current command value obtained by the temperature feedback control. Thus, stable temperature control is realized with less fluctuations of the electric current flowing in the respective heater H1-Hn and less fluctuations of the temperature of the object of temperature control in comparison with on/off control method.

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.
