And some of the state variable values can be installed in the analog component of the injection molding machine. For example, the position detecting unit i2 for measuring the position of the screw U, the pressure sensor 2丨 and the temperature measuring device 22 are mounted on the nozzle 2, and the values of the sorrow variables of the injection molding machines are output to A digital communication device 3 is configured to convert the analogous state variable values into digital communication data. The mold 5 to which the injection molding machine is butted includes a runner 51, a first runner 52 and a cavity 53, and the runner 52 is connected between the runner 51 and the cavity μ. While the washing path 51 and the nozzle 2 are butted against each other, when the molding machine is actuated, the hot sol is injected into the mold 5 through the nozzle 51 through the nozzle 51, passes through the flow path 52, and finally flows into the cavity 53. When the runner 51, the runner 52 is compared with the cavity 53, and the white is filled with the hot melt, the screw 11 is originally converted into a hot melt filling, and the J 1 is converted into a suitable pressure for the injection of the hot melt. Features. The volume of the hot sol in the mold 5 shrinks as the hot sol cools. At this point, the screw 〗 〖In order to keep the hot sol at the appropriate pressure will squeeze the additional hot sol into the mold $ ^ called pressure holding operation' purpose is to avoid the hot sol in the uncooled, 曰 hard road 6 M423041 ♦ Wi, » 51 flows out while avoiding the need to produce the desired molding due to hot melt cooling. The state variables of the plurality of injection molding machines measured, such as the displacement amount of the screw 11, the screw speed, the nozzle pressure, the nozzle temperature, and the variation of the four signals are used as the numerical outputs of the state variables. The position detecting unit 12 is configured to detect the actual position of the screw u and transmit the voltage signal of the position detecting unit 12. The pressure sensor 21 is configured to detect the pressure of the lug nozzle 2 and transmit a pressure voltage signal. The temperature measuring device 22 is configured to detect the temperature of the nozzle 2 and convert it into an analog temperature detecting signal; the temperature measuring device 22 can also be a temperature-measuring thermocouple to transmit A small voltage signal of a temperature thermocouple. The voltage signal is received by the digital communication device 3, and the analog state variable value is converted into digital communication data, so that the controller 4 is configured to receive a plurality of actuation signals to control the action of the driver 1 and the controller 4 operates. The method is that the user puts a control command on the man-machine interface, and then converts it into a speed control signal through the controller 4 and outputs it to the screw 11 to achieve the control speed. The screw 丨丨 itself will turn the signal to the speed back. The device 'received by the speed feedback device to the driver i, the driver 1 can be compared with the input' to decide to accelerate or decelerate, thereby achieving closed loop control. The voltage signal outputted by the position detecting unit 12 is used to detect the current position of the nozzle 2 for the controller 4 to determine whether it has reached a predetermined position of the original plan. If there is a 7 M423041 error, the controller 4 will adjust the speed control signal. To the driver, such as: Increase the output current to reduce the error, in order to achieve accurate positioning and speed control. The controller 4 has a conversion unit and a correction unit. The conversion unit switches the human interface to receive the actuation signal to be converted into an applicable control code, and the modified unit is coupled to the conversion unit, the position detecting unit 12, and the pressure sensor. The temperature measuring device 22 is configured to adjust and correct the original data according to a pressure value of the position detecting unit 12 or the pressure sensor 21 or an error detecting signal of the temperature detecting device 22 of the temperature measuring device 22. In order to output the correct actuation signal and output the corrected actuation signal to the driver, the driver will operate according to the correct actuation signal. In summary, this case is not only innovative in terms of space type, but also can enhance the above-mentioned multiple functions compared with the customary items. It should fully comply with the novelty and progressiveness of the new patent requirements of the law, and apply for it according to law. The bureau approved this new type of patent application, in order to encourage creation, to the sense of virtue.
