摘要： PURPOSE:To easily and certainly set injection pressure without requiring skill by setting at least injection pressure to one pressure value on a low pressure side to perform molding and subsequently calculating injection pressure eliminating filling deficiency in a molded product and capable of obtaining a good product and applying pressure correction accompanied by the alteration of other molding condition thereto to set molding conditions. CONSTITUTION:As an initial condition, at least injection pressure is set to one pressure value on a low pressure side and, further, an injection speed is set to one speed value on a high speed side to set the injection start position of a screw to a final retreat position. After molding, injection pressure is increased corresponding to the filling deficiency of a molded product and injection pressure capable of obtaining a good product is calculated. The correction pressure accompanied by the alteration of other molding condition is added to or subtracted from the obtained injection pressure. For example, when the injection speed is reduced, correction pressure is set on the basis of the fluctuation pressure due to the override characteristics of a drive part and added to injection pressure to stabilize an injection speed.

摘要： PURPOSE:To easily and certainly set molding conditions even by an unskilled operator by calculating an average injection speed from injection speeds and setting the obtained injection speed as a molding condition. CONSTITUTION:The average injection speed Va during the period of the injection stroke Si at a time when a good product is obtained is calculated. An injection speed is set to one speed value Vh on a high speed side according to an initial condition but the injection speed V at the time of actual molding becomes far smaller than the injection speed Va. Therefore, the average injection speed Va is calculated to be set to a controller 12 as a molding condition. In this case, the average injection speed Va may be calculated by dividing the injection speed V sampled at a definite short time interval by the sampling number of times. Further, the area of a speed characteristic to the position of a screw 3 is calculated and this area may be divided by a position to be averaged.

摘要： PURPOSE:To designate, alter over-ride characteristics without altering a hydraulic circuit by so controlling a charging mechanism that resin is charged at a charging speed having a predetermined correlation with respect to a measured load pressure. CONSTITUTION:An injection screw 12 is driven by a hydraulic pump 14 disposed in a heating cylinder to inject, charge resin of molten state in the cylinder in a mold, and a pressure sensor 16 measures a hydraulic pressure for driving the screw 12 to be regarded as being a load pressure of an injection molding machine. A microprocessor 20 having functions of calculating means and control means stores the measured pressure of the sensor 16 in a RAM 24, obtains a charging speed of the screw 12 having a predetermined correlation with respect to a hydraulic value based on the hydraulic value by using the calculating function, and so controls the pump 14 as to charge the resin in the mold at the obtained charging speed, thereby setting over-ride characteristics to a desired pattern.

摘要： PURPOSE:To facilitate an automatic changing of molds in an unmanned factory or the like, to reduce cost to a great extent, to enhance accuracy in control and to make structure of the mold simple and compact. CONSTITUTION:For changing of a mold 2 for an injection molding machine, characteristic data D2 of a sensor, for instance a pressure sensor 3, to be incorporated in the mold 2 are measured beforehand, and the measured data D2 and identification code D1 of the mold 2 to which the characteristic data D2 are incorporated are stored in a memory. In changing of the mold, characteristic of a control system 5 that processes signals Sd detected from the pressure sensor 3 is corrected, for instance by means of gain correction or zero correction, in accordance with the characteristic data D2 corresponding to the identification code D1 of the mold 2 to be changed.

摘要： PURPOSE:To judge simply stability of a resin filling process by providing a control device wherein a plurality of physical quantities of operation are continuously detected through a detecting means detecting the physical quantities of operation and products of a plurality of physical quantities of operation are continuously obtd. through an operational means and the results of operation are displayed graphically on a displaying means. CONSTITUTION:A control device 20 detects continuously loading pressure and resin filling speed through a loading pressure detecting means 16 and a filling speed detecting means and operates continuously the energy quantities of a resin through an operational means 20 and displays graphically the operational results on a displaying means 22. Only a graph illustrating change in an energy quantity of the resin can be displayed as a graph illustrating the change on the displaying means 22. Therefore, as an operator can evaluate stability of a molding process by watching only the graph of the energy quantity of the resin, it is possible to judge quickly and accurately.
