摘要： A method of controlling a motor for injection molding against overheating. The motor current is sampled at given intervals, and the square of each sampled value is multiplied by the corresponding sampling period. A number of products or values thus obtained during a cycle of injection are summed. This sum is divided by a value which is obtained by multiplying the square of the maximum current value by the ratio of heat dissipation at the continuous rated current to heat dissipation at the maximum current. If the period of a cycle of injection subtracted from the above resultant value is positive and the motor is somewhat overheated, then themotor is put at rest and set for a longer cycle of injection (S8 to S11).

摘要： An injection molding machine and a method of controlling a back pressure thereof wherein a drag (frictional force) generated by a transmission mechanism interposed between a servo motor for injection and a screw is reflected on a set back pressure, in order to correctly control the set back pressure for the screw during the metering and kneading. A torque limit value and a rotational direction of the servo motor (M2) for injection are determined in each of the steps depending upon the relationship between the set back pressure and the drag for the transmission mechanism in each of the steps of metering and kneading. A torque limit is applied to a servo circuit (3) of the servo motor (M2) for injection depending upon a set torque limit value, and the servo motor (M2) for injection is driven in a predetermined rotational direction.

摘要： A corresponding relationship between injection steps and injection velocities which are initially set in an injetion condition file is graphically represented on a display screen, and a starting point (P1) and a terminal point (P2) are designated on the graph to set a correcting section. Then a shape of a line segment connecting the starting point (P1) and terminal point (P2) to each other is selected out of a straight line and an arc for designation. In this manner, the section between the starting point (P1) and terminal point (P2) constitutes a new injection step. Futhermore, an injection velocity does not always have a constant value in the new injection step; it can be optionally set in a manner to linearly increase or decrease or change in an arc.

摘要： A method of monitoring, capable of properly, integrally controlling the operating conditions and the operation histories of a group of injection molding machines. Sets of monitoring data delivered from respective injection molding machines are periodically detected by the processor of a monitoring device, and a plurality of the latest monitoring data for respective injection molding machines are updatably stored in a plurality of data tables. When a timer (Ti) relating to any one of the injection molding machines times out or a current injection count (Rill) reaches a predetermined count (CNi) (206, 216), it is decided a monitoring data output timing has been reached, and, it is further discriminated as to whether the monitoring data are to be printed or displayed on a screen. During a printing process or display process (208, 210, 218 and 220), sets of the oldest monitoring data, sets of the second oldest monitoring data or a group of the oldest data consisting of said both sets of data and calculated monitoring data fluctuations relating thereto are printed or displayed first, and groups of similar data are successively printed or displayed with the oldest one first. When printing or displaying of the group of the latest data including the sets of the latest monitoring data is completed, monitoring data rewriting process is performed (211, 221) in order to update a plurality of sets of monitoring data in preparation for the succeeding monitoring data output.

摘要： A method of discriminating non-defectives from defectives in an injection molding machine capable of properly and quickly setting discriminating reference parameters and accurately discriminating non-defectives from defectives. In each of a plurality of injection steps during molding of non-defectives, a group of injection pressure curves as a function of screw position and a group of injection pressure curve as a function elapsed time after the start of the injection are displayed in two coordinate systems on display screens on the basis of injection pressures and screw positions, both of which are sampled periodically. For respective screw positions and elapsed times selected in the coordinate systems, various reference values (x, p, t) and various upper and lower limit values (pu, pl, tu, tl, xu, xl) for determining various tolerance ranges are set in data display columns (8, 9) in consideration of distributed states of the groups of pressure curves and displayed details displayed in a data display column (10) and variable in accordance with the movement of cursors (11, 12). During the execution of the real molding cycles, real elapsed times and real injection pressures at respective selected screw positions, or real screw positions and real injection pressures at selected elapsed times are compared with the tolerance ranges to determine their suitability, thereby discriminating non-defectives from defectives on the basis of the number of discriminated defectives.

摘要： A method and apparatus for pressure control of an electrically powered injection molding machine capable of smoothly controlling the pressure stepwisely without mounting any particular servomotor on the injection molding machine or without replacing a servomotor once mounted by another servomotor. At the time of transfer from an injection step to a first pressure-maintaining stage and at the time of transfer from the pressure-maintaining stage to a next pressure-maintaining stage, the CPU for numerical control calculates a correction quantity (S7) by dividing a value obtained by subtracting a maximum injection pressure or a torque limit value in the pressure-maintaining stage before transfer from a torque limit value in the pressure-maintaining stage after the transfer, by a required number of times of correction that is obtained by dividing a predetermined switching time in the pressure-maintaining stage after the transfer by a period for executing the pressure-maintaining control operation. Then, the correction quantity is added for every period to gradually renew (S8) from the maximum injection pressure or the torque limit value in the pressure-maintaining stage before transfer up to the torque limit value in the pressure-maintaining stage after the transfer. The maintained pressure practically applied to the screw from the injection servomotor controlled by the servo control CPU varies favorably following the torque limit value that is gradually renewed, and whereby the multi-step pressure control is smoothly carried out.

摘要： A system for switching and controlling a unit amount of torque limit values of a servo motor for an injection molding machine, in which a torque instruction (e) from a servo circuit (8) to a servo motor (M) for driving the injector is so controlled that the injection pressure, keeping pressure and back pressure are set at their optimum values. At the time of measurement, the output level of a D/A converter (9) which receives a torque limit instruction (g) is decreased at a constant rate to decrease the unit amount of torque limit level compared with the time of injection, so that the unit amount of torque limit for the back pressure at the time of measurement becomes smaller than that of torque limit for the injection pressure and keeping pressure at the time of injection. In comparison with the time of injection, therefore, the torque limit values at the time of measurement and kneading can be set smaller and finely in smaller unit amounts.

摘要： Display for an injection molding machine, characterized in that it is formed so that set values of the metering and kneading conditions can be graphed on a CRT picture frame (20) so as to easily discover errors in the set conditions, including the number of revolutions per minute, back pressure and switching position, which are used during metering and kneading operations, of a screw. The number of switching steps in the metering and kneading treatment, and a back pressure, the number of revolutions per minute of a screw and a position to which the screw is to be switched in each switching step are set through a keyboard (21) and stored in a memory (15). A microcomputer (14) is adapted to discriminate a maximum value of each of the back pressures, the numbers of revolutions per minute of the screw and positions to which the screw is to be switched, and determine the scale factors for the back pressure, revolution number and screw position on the basis of the discriminated maximum values referred to above. The relation between a screw position and its back pressure and the relation between a screw position and the number of revolutions per minute of the screw are displayed on the CRT picture frame (20) on the basis of the scale factors corresponding to the set back pressure, the set number of revolutions per minute of the screw and the set position in which the screw is to be switched in each step.
