Embodiment Construction

[0043] As shown in FIG. 1 , the injection molding machine 10 is basically composed of a clamping device 12 for clamping a die 11 and an injection device 13 for injecting resin into the die 11 . The injection molding machine 10 is equipped with a control device 20 including a neural network.

[0044] The control device 20 includes a neural network 21 for combining the measured monitoring values ​​and the injection monitoring values ​​of the test molding performed by the injection molding machine 10 and generating a prediction function; The prediction function, and the measurement monitoring value of the mass production molding performed by the injection molding machine 10, to calculate the first value; the second calculation unit 23 is used to calculate the corresponding value according to the first value calculated by the first calculation unit 22 The second value of the injection condition; the comparison unit 24 is used to compare the first value and the injection monitoring...

Abstract

An injection molding control method that uses a neural network is disclosed. The control method determines an injection condition according to a prediction function, a first value, and a second value. The prediction function is implemented in test molding, and the first value and second value are implemented in a measurement step that has a time margin. The injection condition predicted for mass-production molding is determined prior to the injection step, and the need for computation during the injection step is thereby eliminated.

Description

technical field [0001] The invention relates to a method for controlling an injection molding machine by using a control device comprising a neural network. Background technique [0002] The quality of the product obtained in an injection molding machine used to produce a product by performing the plasticizing / measurement process (hereinafter referred to as the measurement process) and the injection / pressure holding process (hereinafter referred to as the injection process) depends on the injection conditions, so it is important to Adjust the injection conditions so that a satisfactory product is obtained. [0003] Injection conditions include V-P switching control for switching screw control from speed control to pressure control, a technique for obtaining qualified products by correcting the V-P switching position is disclosed in JP2005-335078 A. [0004] Injection conditions during the above injection molding will be described below with reference to the graph of FIG. 18...
