Problems solved by technology
For molded products, the molded products molded at the beginning of production just after starting the injection molding machine and the molded products molded in the subsequent stable production period, even if molded under the same molding conditions, the quality or finished product rates sometimes vary
Furthermore, when the molded product is continuously molded under the same molding conditions at the initial stage of production and the stable period as described above, the injection molding machine may detect an abnormality and stop midway.

The invention provides an injection molding machine, a control method thereof, and a recording medium storing a control program thereof. The injection molding machine can automatically determine whether a conversion molding condition is used or not. According to one embodiment of the present invention, there is provided an injection molding machine which is controlled by a control device in accordance with molding conditions and which injects and fills a molding material in a flowable state into a mold to perform molding, the control device comprising a molding condition storage device which stores the molding conditions, and a determination device which determines whether the molding material is in a flowable state or not. The molding conditions include at least one transition molding condition from a state in which the molding is stopped until the normal molding is performed, and a normal molding condition when the normal molding is performed, and the determination device determines the molding condition based on at least one of the time from the start of the molding stop and the temperature at a predetermined position from the start of the molding stop; therefore, whether or not molding using the transition molding conditions is performed is determined.
Description
technical field [0001] The present invention relates to an injection molding machine, a control method of the injection molding machine, and a recording medium for storing the control program of the injection molding machine Background technique [0002] In general, an injection molding machine repeats operations of injecting a flowable molding material into a closed mold, curing the molding material in the mold, opening the mold, and taking out a molded product. For molded products, the molded products molded at the beginning of production just after starting the injection molding machine and the molded products molded in the subsequent stable production period, even if molded under the same molding conditions, the quality or finished product Rates also sometimes vary. Furthermore, when molded products are continuously molded under the same molding conditions during the initial stage of production and the stable period as described above, the injection molding machine may ...
