    摘要: An injection is carried out under a certain molding condition with a nozzle in an injection molding machine left open to sample an injection pressure Pr in every certain cycle for storing. Detected pressure data Pr(0) to Pr(N) for one shot is stored as reference pressure data Pr0(0) to Pr0(N). When defective molding occurs or when a resin lot is changed or the like, the injection is carried out with the nozzle left open under the same molding condition as that used in obtaining the reference pressure data and obtain the detected pressure data Pr(0) to Pr (N). Waveforms of the detected pressure data Pr(0) to Pr (N) and reference pressure data Pr0(0) to Pr0(N) are graphically represented so that variation of the molding condition is observed. It is assumed that if there are any differences, a problem presumably resides in resin, while if there is no difference but the defective molding occurs, the problem presumably resides in a mold.

    摘要: There is provided a method of and a device for collecting knowledge of an injection molding technique capable of collecting knowledge of an injection molding technique from a number of expert engineers without a knowledge engineer, and also collecting machine operation data obtained in performing an injection molding operation in accordance with the knowledge of the injection molding technique. A plurality of injection molding machines (2-N) are connected to a server computer (1) through a network (LAN). A predetermined rule for collecting an expert engineer's knowledge of the injection molding technique is stored to be executable in the server computer (1). Each of the injection molding machines (2-N) is provided with an input device (3-N) for allowing an operator (E-N) to input data utilizing the predetermined rule. When a problem such as a molding defect occurs in an injection molding machine (2-N), an expert engineer (E-N) takes a countermeasure against the molding defect, such as modification of set values of molding conditions. The items of the modified conditions, the set values of the molding conditions before and after the modification by the expert engineer, and machine operation data before and after the modification of the molding conditions, are sent to the server computer (1) to be stored. Thus the knowledge of the appropriate countermeasure which the expert engineers have, and the actual machine operation data before and after taking the countermeasure, are stored in the server computer (1) so that qualitative and quantitative data are utilized for finding an appropriate countermeasure against the molding defect.

    摘要: A method of and an apparatus for precisely determining a separating force of a molded product (3) from a mold (2a) by an ejector in an injection molding machine. A load exerted on an ejector mechanism (9-12) in operation without a product (3) molded in the mold (2a) is constituted by an inner resistance of the ejector mechanism (9-12). The inner resistance includes frictional force produced within the ejector mechanism (9-12) and resilient forces of springs (12) for returning ejector pins (11) to retracted positions thereof. On the other hand, the load exerted on the ejector mechanism (9-12) in operation with a product (3) molded in the mold (2a) is constituted by the inner resistance and the separating force of the molded product (3) from the mold (2a). Thus, a difference between the loads detected in driving the ejector mechanism (9-12) with and without a molded product (3) at each ejector position precisely represents the separating force of the molded product (3) from the mold (2a). Judgment on defectiveness/ non-defectiveness of the molded product (3), and abnormality of the injection molding operation and the ejector mechanism (9-12) are performed more precisely based on the determined separating force of the molded product (3).
