    摘要: A closure position detection mode is provided so as to obtain a rate of variation (which encompasses an amount of variation) in a physical quantity to a predetermined amount of movement of a movable platen or a crosshead, and detect, as a mold closure position, a position when the variation rate reaches a preset ratio. The mold clamping apparatus is previously operated in the closure position detection mode so as to store, as a reference value, the mold closure position at which a target mold clamping force is obtained. In production operation, the mold clamping apparatus is operated in the closure position detection mode so as to obtain an actual mold closure position (detection value). The mold clamping force is corrected on the basis of a deviation of the detection value from the reference value.

    摘要: A toggle mechanism is supported at the front face of the housing and a forward end of the toggle mechanism is connected to a back face of the movable platen. Upon the closing and opening of dies, the toggle mechanism is stretched and contracted to move the movable platen forward and backward along the tie bars. An automatic control device calculates, before the dies are mounted, from a die thickness input and the kind of the dies input, such a stop position for the link housing as impart a target value to the stretching/contraction amount that the toggle mechanism has when the dies are in closed state, and calculates, from the kind of the dies input, an appropriate contraction amount greater than the target value, and the automatic controlling device moves the link housing to the stop position calculated and the toggle mechanism by the appropriate contraction amount calculated.

    摘要: The invention relates to a novel method for producing precision parts, especially flat optical data carriers. According to the invention method, the embossing procedure is program-controlled on the basis of the path function of an electromechanical or hydraulic drive of the driven mold half. When a servomotor is used, the internal path signal thereof can be directly used for calculating the path function or for operating the program control. The novel method allows for a complete speed control of the embossing phase. All factors that can be mechanically influenced from the exterior are detected in more detail for the conditions before and during the embossing phase, thereby allowing for an optimum precision and reproducibility.

    摘要: In a control device for a motor-driven injection molding machine comprising a mold clamping system which comprises a servo-motor and a ball screw mechanism, the ball screw mechanism comprises a screw shaft and a nut for use in converting rotation of the servo-motor into rectilinear motion. The control device comprises a pattern generator for generating a set pattern for the clamping force. The mold clamping system generates a clamping force according to the set pattern and a maximum clamping force with the set pattern being determined to be larger than the clamping force that is generated by the servo-motor within predetermined ratings.

    摘要: A disc base molding method and apparatus are provided for the injection molding of disc bases so as to produce thin disc bases having increased signal transfer clarity with a shortened molding cycle. Upon closure of a mold, a signal is sent to a mold clamping start delay timer and an injection start delay timer. Pressure is increased for mold clamping at approximately the same time that molten resin is introduced into the mold cavity. The time period from the start of pressure increase when the molten resin is initially introduced to the mold cavity until a specific mold clamping force is reached, is controllable. Upon completion of the injection of the molten resin, the mold clamping force is maintained until the molten resin is solidified.

    摘要: A control device for an injection molding machine includes a pattern generator for generating a set pattern of clamping forces. The pattern generating calculates a travel distance of a movable member in the mold clamping system according to the set clamping force and generates the set pattern having an allowable range of deviation that is defined by an upper limit and a lower limit relative to the calculated travel distance. The mold clamping system continuously decreases the clamping such that it falls within the range defined by the allowable range of deviation after the clamping force reaches the value defined by the upper limit.

    摘要: A method and apparatus for automatically setting the die height platen on a toggle-operated injection molding machine to achieve a desired mold clamping force. A control is provided and contains information relating a desired clamp tonnage with a toggle crosshead displacement, in order to permit setting the die height platen for a particular set of molds so that the clamp, when operated, will automatically provide the desired clamping force between the mold members. The adjustment is provided by moving the die height platen in response to deviations from a predetermined set of conditions, the die height platen being moved by an hydraulic motor and chain drive to shift the die height platen along guide rods that extend between the die height platen and a stationary mold platen.

    摘要: A method and apparatus for controlling the hydraulic pressure in an hydraulic clamping cylinder to correspond with a desired clamping force and to compensate for overshoot of the hydraulic pressure caused by time delays in operating the components in the hydraulic circuit. The control arrangement involves the sensing of the actual hydraulic pressure during the clamp force maintenance portion of a clamping cycle and comparing the actual pressure with a desired pressure to provide a correction signal to be utilized to control the operation of the hydraulic system during the next succeeding cycle so that the actual hydraulic pressure during the clamp maintenance portion of the clamping cycle during the next succeeding cycle results in a clamping force that is closer to the desired clamping force.
