摘要： A strain gauge arrangement for die casing machines of the type having tie bars with threaded ends, comprises an unthreaded, uniform intermediate portion on at least one of the tie bars, which defines a measuring region with interior and exterior ends. An elongate aperture extends through the end of the one tie bar, and terminates at a base that defines the interior end of the measuring region. A detector rod is telescopingly received in the aperture, and has its inner end resiliently urged into continuous contact with the base of the aperture. A sleeve is slidingly received over the outer end of the detector rod, and has its inner end resiliently urged into continuous contact with a shoulder which defines the exterior end of the measuring region. A measuring device detects changes in the relative position of the outer ends of the detector rod and the sleeve to determine strain in the measuring region of the one tie bar.

摘要： A structure for measuring the load imposed on mold halves in a plastic injection molding machine when engaged to define a mold cavity, the machine being of a type wherein a movable die platen is driven along supporting tie rods to carry one mold half toward and away from a fixed die platen carrying the other mold half. The measuring is accomplished by a sensor engaging one end of one tie rod to sense any movement thereof under an imposed load condition.

摘要： An injection mold with locking device comprises a fixed backing plate and a fixed mold part plate which are connected to each other by four tie rods. A movable mold part plate is connected to the fixed backing plate through a drive and locking mechanism which is capable of moving the movable mold part plate into a mold position with the fixed mold part plate. A thermal force control apparatus is associated with one or more of the tie rods for changing the temperature of the tie rods and thereby causing the tie rods either to expand or contract. By such expansion or contraction, the exact force applied between the fixed and movable mold part plates can be adjusted to a desired level.

摘要： Apparatus is disclosed for indicating the final tonnage produced by a press having a toggle mechanism actuated by a closing means. The apparatus comprises means for measuring the closing force exerted on the toggle mechanism by the closing means, means for detecting the initial peak closing force measured by the measuring means, means for converting the initial peak closing force to a final press tonnage value preferably using a proportional relationship, and means for outputting the final press tonnage value. In addition, the apparatus may include switch means for disconnecting the measuring means from the detecting means after the detecting means has detected the initial peak closing force. The apparatus is easily adaptable to most presses having toggle mechanisms such as those used in injection molding machines, and may be used to provide an accurate tonnage indication without the necessity of directly measuring tonnage such as by mounting strain gages on the tie bars.

摘要： In a method for controlling or regulating a closing mechanism of a moulding machine, a first trajectory for the controlled or regulated movement of the movable platen is calculated using a first algorithm based on operator inputs relating to the desired movement of the movable platen, and the movable platen is moved in a controlled or regulated manner at least once according to the first trajectory. At least one dynamic or kinematic variable of the closing mechanism is measured during at least one of the movements of the movable platen according to the first trajectory, and an estimate of at least one parameter value is generated based on the measurement. A second trajectory for the controlled or regulated movement of the movable platen is calculated based on the estimate, and the movable platen is moved in a controlled or regulated manner according to the second trajectory.

摘要： An injection molding device includes a housing having a door, an injection molding machine, a detection section, and a control section. The control section controls voltage applied to the mold clamping motor, and performs mold-clamping and mold-opening of the upper mold and the lower mold by either moving the injection unit and the upper mold along the vertical direction or by moving the lower mold along the vertical direction. The mold clamping device further includes a first brake section that, when application of voltage to the mold clamping motor is stopped, regulates movement of the injection unit and the upper mold in the vertical direction or movement of the lower mold in the vertical direction. When the detection section detects that the door is open or detects intrusion of foreign matter, the control section stops application of voltage to the mold clamping motor.

摘要： To easily check a changing trend of machine state data on an injection molding machine during a predetermined period and/or in every predetermined period. An injection molding information management support device for managing machine state data regarding a machine state in operation of an injection molding machine during a predetermined period and/or in every predetermined period includes a machine state data acquisition unit that acquires a machine state data value for each molding cycle in the injection molding machine, and a frequency distribution data recording unit that converts the machine state data value into a preset class data value and records the class data value in a storage unit.
