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： A resin flow analysis in a die is performed by CAE or the like to obtain a resin pressure curve at a resin inlet port. Injection (air shot) is performed while a nozzle is separated from a die, so that an injection pressure curve Pa to be detected at this time is obtained. From the injection pressure curve and the resin pressure curve, an injection pressure command curve serving as a molding condition in mass production is obtained. The resin pressure curve obtained by the resin flow analaysis is compensated by the injection pressure curve in an air shot for a time lag and pressure loss caused by the mechanical elements of an injection molding machine, so that molding conditions in mass production can be easily obtained.

摘要： PROBLEM TO BE SOLVED: To simply grasp molding characteristics. SOLUTION: A nozzle of an injection molding machine is opened to inject under predetermined molding conditions. Its injection pressure Pr is sampled at each predetermined period, and stored (A3 to A6). Detected pressure data Pr(0) to Pr(N) for one injection are stored as reference pressure data Pr0(0) to Pr0(N) (A7). Meanwhile, the nozzle is opened under the same molding conditions as those when the reference pressure data is acquired such as when a molding fault occurs, when a resin lot is changed or the like to inject, thereby obtaining detected pressure data Pr(0) to Pr(N). Waveforms of the detected data Pr(0) to Pr(N) and waveforms of the reference data Pr0(0) to Pr0(N) are graphically displayed, and change of the molding characteristics is observed. If there is a difference therebetween, there are problems in the molding machine and the resin. If there is no difference therebetween and a molding fault occurs, it is inferred that there is a problem in the mold.

摘要： PROBLEM TO BE SOLVED: To obtain an injection pressure curve of a molding condition by a simple method utilizing a resin flow analyzing result by CAE. SOLUTION: The resin flow in a mold is analyzed by CAE or the like to obtain a resin pressure curve Ps at a resin inflow port or a resin pressure curve Pn at the end part of the nozzle of a molding machine. Injection (air shot) is performed in such a state that a nozzle is separated from a mold and the injection pressure curve Pa detected at this time is obtained. An injection pressure command curve P as a molding condition at a time of mass-production is obtained on the basis of the injection pressure curve Pa and the resin pressure curve Ps or Pn. The time delay and pressure loss caused by the machine elements of an injection molding machine are compensated by the injection pressure curve Pa of the air shot with respect to the resin pressure curves Pa, Pn obtained by the analysis of the resin flow and the molding condition of mass-production molding can be simply obtained. The pressure loss Ploss of a nozzle part is also calculated to obtain the injection pressure command curve P on the basis of Ploss, Pa and Ps.
