摘要： A molding system including a mold and a molding machine has been adapted to monitor the position of mold element surfaces that move relative to each other to form a mold cavity. The system includes a source of gas under pressure and orifice-forming sensors on a first mold element to direct a flow of pressurized gas from the first mold element. A monitoring system monitors the condition of the gas remote from the first mold element to indicate the spacing between the first mold element and one or more adjacent mold elements as the mold elements move with respect to each other. The molding system can monitor the operation of large, complex die-casting molds that include a plurality of slides movable transversely to the movement of the molding machine and measures and indicates misalignment and warping of die elements, failure of the die elements to close and open properly, and other such irregularities in operation in the presence of the extremely high forces imposed upon the molds by the molding machine, high temperatures and hostile environment and to protect molds and molding machine parts from destructively high forces and to prevent or record manufacture of reject parts.

摘要： A control arrangement for moving tools brings these tools quickly into a desired position smoothly and without shock. The arrangement comprises means for preadjusting the required displacement so that the whole displacement path corresponding to the movement sweep of the tool is first determined. A calculation member (4) converts a given delay of the tool movement into a value corresponding to the speed of movement. An integrator (6) derives from the calculated speed value as a function of time a required position value. Upon movement of the tool the means for preadjusting the required displacement are continuously readjusted and the adjusted value for the drive (25) is determined by means of a comparison with the position value supplied by the actual displacement pick-up device (8).

摘要： A method of detecting and compensating for a non-operational mold cavity in an injection molding apparatus having a plurality of mold cavities and an injection molding screw or ram includes injecting, via the injection molding screw or ram, a molten thermoplastic material into the plurality of mold cavities. The method includes measuring a first process parameter of the injection molding apparatus at a pre-determined time during or after the injecting. The method also includes determining, based on the first process parameter, whether one or more mold cavities of the plurality of mold cavities are non-operational. Then, when it is determined that one or more mold cavities are non-operational, the method includes automatically adjusting the first process parameter or a second process parameter of the injection molding apparatus.

摘要： A shrinkage detection device for a polymer injection molding apparatus detects a shrinkage experienced by an injection molded element for assessing a quality of the molded element. Shrinkage, along with temperature and pressure of the melt within the mold during cooling, indicates a sufficiency of the resulting molded element for intended purposes. Sufficiency includes parameters such as flexibility, shear strength and longevity, and is accurately performed can replace conventional sample testing of molded articles that are expensive and time consuming.
