摘要： An injection/hold pressure control apparatus which permits the production of high-quality molded articles without the need of using an expensive internal mold pressure sensor. When a plurality of points specifying a target injection/hold pressure curve represented as a function of the time period elapsed after the start of injection are manually input in succession, a processor (109) of a numerical control unit (100) calculates a group of target injection/hold pressure data on the basis of the target pressure curve drawn on a screen of a display unit (113), and stores them in a lookup table in a shared memory (102). Upon start of the injection, a comparator (11), connected to a pressure sensor (4) mounted on an injection screw (1) for detecting an actual injection/hold pressure, is connected to the numerical control unit through a first changeover switch (6). The target pressure data is successively read out from the lookup table and delivered to the comparator, and the drive of an injection servomotor (2) is controlled by a torque control section of a servo circuit (200) responsive to the comparator output indicating the deviation between the actual pressure and the target pressure, so that the injection/hold pressure is always controlled to a proper value in a closed-loop, to thereby improve the quality of molded articles.

摘要： An injection apparatus of an injection-molding machine is described, including a servomotor for screw rotation including a pulse coder, the motor being driven in accordance with the difference between a command output from a control section of the injection-molding machine and an output from the pulse coder, thereby rotating a screw. During injection and pressure hold processes in which the motor is rendered nonoperative, the screw rotates as molten resin flows backward, if a check valve attached to the screw does not function normally, and this situation is detected as an abnormality of the check valve by a control section.

摘要： An automatic mold thickness adjusting method is provided, which is capable of effecting mold thickness adjustment in a short time by a low-cost mold clamping apparatus using a general-purpose motor for mold thickness adjustment, and of preventing an overcurrent from flowing in the motor. A crosshead is retreated to a position behind a position (LO) for production of a set mold clamping force when the crosshead reaches a lock-up position before a die-touch state is attained, or when the die-touch state is established in a crosshead position before the aforesaid position (LO), and a rear platen is advanced so that the die-touch state is attained. Thereafter, the motor for mold thickness adjustment is driven in a direction to retreat the rear platen, and at the same time, a servomotor is driven in a direction to advance a movable platen, at a speed equal to the retreating speed of the rear platen obtained by multiplying a program-specified speed by an override value corresponding to a crosshead shift position, thereby causing the crosshead to reach the aforesaid position (LO).

摘要： A method for positioning an operating unit of an electrically-operated injection molding machine at a predetermined operating position in an optimum manner, by using widths of positive-side and negative-side regions of an allowable positioning zone which are set independently of one another in accordance with the operating direction of the operating unit and the function to be achieved by the operating unit. Positioning of a screw at an injection-end position is completed when the actual screw position (PA) is equal to or less than the sum of a target injection-end position (PS) and the positive-side region width (W1), which is set to "0", and is equal to or larger than the value obtained by substracting the negative-side region width (W2) from the target position (PS), so that the screw is positioned at the target injection-end position or a screw-moving position which slightly exceeds the target position by a permissible distance, to thereby actually control an amount of shot.

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： A method for removing resin clogging a nozzle in a motor-driven injection molding machine, which is capable of removing resin clogged in the nozzle without an excessive load being continuously applied to a servomotor for driving a screw.When the nozzle is clogged with resin, pulse distribution to a servo-circuit is started to move the screw to a foremost position thereof (S1). If a feed stop state, wherein the pulse distribution is stopped by an increase of the deviation of an actual movement amount from a command movement amount for the servomotor above a predetermined value, is not ended before passage of a time set by a timer started at the time the feed stop state occurs (S3-S6), the forward movement of the screw is stopped by an alarm process (S7).

摘要： An injection molding machine includes a numerical control system in communication with a host computer, the numerical control system having incorporated therein a computer, wherein the injection molding machine can itself start and stop in operation on the basis of stored data indicating that the injection molding machine is in a state capable of being operated or in a state incapable of being operated. Pre-processing is executed in response to a start-up signal from the host computer (steps S4 through S9). If a malfunction or abnormality happens during the pre-processing, the location and thus the existence of the abnormality is stored in memory of the numerical control system. After completion of the pre-processing, if the stored abnormalities are judged to be restorable on the basis of the storage contents in the memory, an abnormality restoration processing is executed (S17) and, subsequently, automatic operation is carried out (S11). A terminating process is then executed in response to a stop command from the host computer (S14), and the operation is halted.

摘要： A suckback method and apparatus is capable of positively effecting a suckback operation in an injection molding machine using a servomotor as an injection axis drive source for axially driving a screw. When the screw reaches a metering completion position, screw rotation is stopped and a follow-up operation for an error register is carried out so that an error amount accumulated in the error register becomes equal to zero (steps S1, S4, S5). Then, a torque limit for the servomotor and for application of back pressure is released (step S8), and the screw is driven backwardly by the servomotor by a predetermined suckback amount (step 11).
