摘要： A device and a method for detecting condition of molds attached to an injection molding machine with low cost and high reliability. A load exerted on a product ejecting mechanism or a mold opening/closing mechanism is estimated by a disturbance torque estimating observer. An index value (maximum value or average value) of the load is obtained and stored in each molding cycle of the injection molding machine. Obtained values of the index are displayed as a graph on a display device to indicate variation of the load in time series and thus allow an operator to monitor the condition of the molds.

摘要： A method of and an apparatus for precisely determining a separating force of a molded product from a mold by an ejector in an injection molding machine. A load exerted on an ejector mechanism in operation without a product molded in the mold is constituted by an inner resistance of the ejector mechanism. The inner resistance includes frictional force produced within the ejector mechanism and resilient forces of springs for returning ejector pins to retracted positions thereof. On the other hand, the load exerted on the ejector mechanism in operation with a product molded in the mold is constituted by the inner resistance and the separating force of the molded product from the mold. Thus, a difference between the loads detected in driving the ejector mechanism with and without a molded product at each ejector position precisely represents the separating force of the molded product from the mold. Judgment on defectiveness/non-defectiveness of the molded product, and abnormality of the injection molding operation and the ejector mechanism are performed more precisely based on the determined separating force of the molded product.
摘要翻译：一种用于在注射成型机中通过喷射器精确地确定模制品与模具的分离力的方法和装置。在模具中没有产品模制的情况下，施加在喷射器机构上的负载由喷射器机构的内部阻力构成。内部阻力包括在排出器机构内产生的摩擦力和弹簧的弹力，用于将顶针返回到其缩回位置。另一方面，在模具中模制的产品的操作中施加在喷射器机构上的负载由模制产品与模具的内阻和分离力构成。因此，在每个喷射器位置驱动具有和不具有模制产品的喷射器机构中检测到的负载之间的差异精确地表示模制产品与模具的分离力。基于所确定的成型品的分离力，更精确地进行对成型品的缺陷性/非缺陷性的判断，注射成型操作和喷射器机构的异常。

摘要： 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 are connected to a server computer through a network such as 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. Each of the injection molding machines is provided with an input device for allowing an operator to input data utilizing the predetermined rule. When a problem such as a molding defect occurs in an injection molding machine, an expert engineer takes countermeasure such as modification of set values of molding conditions against the molding defect. 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 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, so that qualitative and quantitative data are utilized for finding an appropriate countermeasure against the molding defect.
