Abstract: A method for automatically timely supplying a lubricant to a machine working section driven by a motor and an apparatus therefor. The quantity of increase of the driving current of a mold clamping servomotor (12) during the process in which a mold clamping mechanism (10) of an injection molding machine shifts from a proper lubrication state to an improper lubrication state is previously decided for each combination of the type of the injection molding machine, injection molding conditions, and the type of grease. While a normal injection molding cycle in the proper lubrication state is being executed, a reference value for the motor driving current is decided on the basis of the normal motor driving current in a specific moved position of a movable platen (14), at which the motor current is measured for the aforesaid decision, and the increase of the motor driving current, the reference value and the specific moved position of the movable platen being loaded into a memory of a numerical control device (50). In response to a grease supply timing command, the control device drives a grease pump (40) if the detected value of the motor current in the specific moved position of the movable platen is not smaller than the reference value. Grease from the grease pump is supplied to a predetermined quantity to each of a plurality of parts of the mold clamping mechanism through a distributor (43).

Abstract: A cylinder temperature setting method in which the cylinder temperature distribution obtained in the condition setting operation is realized with fidelity, even when the molding operation is performed on injection molding machines which are different from the injection molding machine used for condition setting in the number and/or positions of heat sources arranged on the injection cylinder. A waveform representing the cylinder temperature distribution is obtained from the relationship between the temperatures of respective cylinder portions detected by thermocouples and the positions of the respective thermocouples when a conforming product is molded by a reference injection molding machine. The obtained waveform is stored and reserved in a record medium. The target values for temperature control of respective cylinder portions of another injection molding machine are obtained based on the reserved waveform, thereby realizing the cylinder temperature distribution obtained in the condition setting.

Abstract: An injection molding machine is equipped with a movable display unit, which provides improved operability and visibility without causing interference with an operator working on the periphery of the injection molding machine and which requires no housing space inside the injection molding machine. A swing arm 40 extends horizontally at the same height as an upper portion of a base 1 of the machine. The swing arm is supported on the base so as to be swingable at its base end portion through a first supporting means 50. The swing arm 40 is positioned between a mold clamping unit 10 and an injection unit 20 along an upper front surface of the base 1. A display unit 30 is supported on the front end of the swing arm through a second supporting means 60 so as to be rotatable in a horizontal plane. The display unit 30 can be set for any desired position or direction by horizontally changing the angle of either the swing arm or the display unit.

Abstract: An injection molding machine having a resin pressure detector in the form of a strain gauge bonded on an annular member (55) which is fixed to a rear end face of a metering bearing housing (41) by bolts (57), and which has a rear end face to which a ball nut (56) is fixed by bolts (59). Upon assemblage, no substantial deformation of the annular member occurs, and hence no zero point shift in the strain gauge is found, so that an accurate detection is achieved by the strain gauge. The maintenance and replacement of the annular member, disposed outside the housing, can be easily performed.

Abstract: 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.

Abstract: A mold clamping apparatus is provided, including upper and lower toggle sections disposed symmetrically with respect to an axis of the apparatus, each toggle section including a ball screw disposed radially outwardly of the apparatus with respect to the axis, a head threadedly engaged therewith, and links operable to expand and bend with reciprocal head motion along the ball screw, each ball screw being directly coupled to a corresponding one of two servomotors connected to a control circuit section including a pulse width modulation control circuit and two transistor inverters. The mold clamping apparatus has primarily structural components separated from the axis so that flexure of the toggle mechanisms and resultant non-uniformity of a pressing force onto the movable platen are eliminated, and each servomotor is small enough to drive a corresponding one toggle section, so that the resultant mold clamp apparatus is low in cost and high in operational response.

Abstract: 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).
