摘要： A method of fastening the mold in an injection molding machine, by using a servo motor (M1) as a drive source for the toggle-type mold fastening device, so that the metal mold can be reliably maintained in a fastened condition without using a braking device. A servo motor (M1) is used as the drive source. When links (L3, L3', L4, L4') of a toggle mechanism (10) that fastens the mold are fully stretched to fasten the mold, a small drive current is supplied to the servo motor (M1) to fully stretch the links (L3, to L4'), so that the mold is maintained under the tightened condition.

摘要： A method of controlling injection of an electrically driven injection molding machine capable of sharply increasing the speed of injection even when a cheaply constructed electrically driven injection molding machine is used. An instruction pulse sequence is supplied to a servo circuit under the condition where the injection servo motor is substantially prevented from rotating by setting to the servo circuit of the injection servo motor a torque limit value (Ts) at which the output torque of the injection servo motor and the resin pressure maintain a balanced state. Then, a deviation between a desired rotational position and the practical rotational position of the injection servo motor reaches a deviation (Fs) in the feed stop position. If the limit on the torque is released at a moment when the deviation in the feed stop position is reached, a large drive current flows into the injection servo motor depending on the practical deviation of position that has increased up to the deviation in the feed stop position, whereby the injection screw is driven with a large torque generated by the injection servo motor and the speed of injection increases suddenly.

摘要： A method of determining conditions for injection molding capable of determining optimum molding conditions quickly and easily, in which, a processor (12) of a control device loaded with an expert system including a condition table listing a plurality of conditions each comprising a combination of information on metallic molds, data on resin, molding conditions, data on faulty molding, and molding monitor data and a weight table listing weighted countermeasures against faulty molding set for every condition, retrieves from said condition table a condition most proximate to a trial injection condition discriminated on the basis of information on metallic mold, data on resin, and molding condition set before start of trial injection, molding monitor data detected during trial injection, and data on faulty molding inputted after finish of trial injection, and, referring to the weight table, determines a countermeasure against faulty molding corresponding to the condition retrieved and greatest in weight. While trial injection is repeated according to the countermeasure against faulty molding with molding conditions changed, the processor changes, as required, weight of the faulty molding countermeasure taken in the previous trial injection on the basis of the result of comparison between faulty molding in the previous trial molding and that in the current one.

摘要： A method of correcting a defective molding in an injection molding machine, wherein the defective molding is restored to an acceptable molding state with the help of an expert system on detection of the defective molding during mass production of a product. When threshold values of a plurality of molding parameters, and information on corrective actions determined on the basis of the knowledge, experience of skilled persons and corresponding to the combinations of evaluations of these parameters, respectively, are manually input through a data input device (119), the threshold values and the information are prestored in a table of a memory (110) under the control of a processor (114). At the start of mass production of the product, an injection time, a metering time and a cushioning amount which have been measured or calculated during a molding cycle, and resin pressures respectively corresponding to screw positions at the time of gate passing and fill-up which have been manually set are set in the table as reference values of parameters. When a defective molding is detected, the processor compares deviations between the respective parameter values during a molding cycle in which the defective molding is detected and the reference values with the threshold values to evaluate the respective parameters, and then, necessary ones of the parameter values constituting the molding conditions are changed in accordance with corrective actions which are read out of the table as required by the combinations of evaluated results.

摘要： A method of making positioning correction on an electric injection molding machine to clamp molds with a toggle mechanism or crank, which intends to eliminate waste of power to be supplied to a servomotor and overheat by locking up in an ideal state the molding machine. A load (RA) acting on the servomotor (7) for clamping molds is detected (S8) during locking-up and, when a value of said load (RA) exceeds a preset reference value (V0), a value (PM) to instruct a position of the servomotor (7) is increased or decreased in the direction for reducing the value of said load (RA) (S12, S13) in the subsequent cycle. As a result, the rotation center (Q1) of a crank (2) and both ends (Q2, Q3) of a link (3) are aligned at the time of locking-up and torque caused by reaction of mold clamping is removed from the rotation center (Q1) of the crank (2). In other words, reaction of mold clamping during locking-up is ensured even without application of driving torque by supplying current to the servomotor (7) for mold clamping. Thus, waste of electric power is prevented, a load on the mold clamping servomotor (7) is reduced, and provision of a stopper or the like for maintaining reaction of mold clamping force is needless.

摘要： An automatic mold exchange type injection molding machine includes a mold clamping portion (2) including fixed and movable platens (3, 4) to which first and second matrices (11, 21) fitted, respectively; a mold exchange robot (6) and a mold stocker (7) which are controlled by a control portion (5); and a temperature controller (8) for the first and second matrices and the mold stocker. A first cavity unit (12) fitted to the first matrix is taken out from the first matrix by moving an arm (61) and turning a chuck (62). Then, it is transferred to the mold stocker and stored in a corresponding storage hole (74) of the mold stocker. Next, another first cavity unit is taken out from the mold stocker, is then transferred to the mold clamping portion, and is fitted to the first matrix. In this manner, the exchange of the first cavity unit is completed. A second cavity unit (22) is exchanged by the same operation as described above, and the mold exchange operation is completed.

摘要： A motor-driven straight acting mold clamping system, which is capable of closing or opening a mold at a high speed without using any large motor and generating a required mold clamping force. When the mold is opened or closed, a ball screw (8) engaged with a ball nut (7) which can be moved unitarily with a moving platen (1) is rotated at a high speed by a motor (17) via gears (13-15) and a clutch (12) to cause a metal mold (3) to be opened or closed at a high speed. During the clamping of the mold, the ball screw (8) is driven by a large rotational force via gears (9, 10), which have a large reduction ratio and which are adapted to amplify the rotational force of the motor, and the clutch (12), so that the metal molds (3, 4) are clamped with a large force.

摘要： A motor-driven straight-acting mold clamping system, which is capable of closing or opening a mold at a high speed without using any large motor and generating a required mold clamping force. When the mold is opened or closed, a ball screw (8) engaged with a ball nut (7) which can be moved unitarily with a moving platen (1) is rotated at a high speed by a coarse adjustment motor (15) via gears (12, 13) to cause a metal mold (3) to be opened or closed at a high speed. During the clamping of the mold, the ball screw (8) is driven by a fine adjustment motor (14) via gears (10, 11), which have a large reduction ratio and which are adapted to amplify the rotational force, and a clutch (9), so that the metal molds (3, 4) are clamped with a large force.
