Abstract: A control system for controlling the operation of a molding machine and its peripheral machines. This control system automatically transmits an advance notification of for example completion of production by the molding machine to an operator by electronic mail. The system includes a destination mail address setting part and an automatic electronic mail distributing part. The destination mail address setting part automatically specifies a transmission destination before a predetermined event such as for example the completion of production at the molding machine occurs. The automatic electronic mail distributing part automatically distributes an advance notification of the predetermined event to the transmission destination before the event occurs.

Abstract: A drive control apparatus is used in an injection molding machine in order to drive and control a servomotor for moving a movable member. Among a plurality of functional sections which constitute a servo circuit connected to the servomotor, at least one functional section (e.g., a safety circuit section, etc.) selected as a functional section having a higher degree of importance is constituted by a hardware circuit section realized without use of software; and the remaining functional section or sections are constituted by a software circuit section realized by making use of software.

Abstract: A control system for a molding machine includes a control unit having a communication function to connect the control unit with a portable data terminal such as a mobile phone through the Internet so that operation of the molding machine can be controlled based on instructions given from remote locations via the mobile phone.

Abstract: An injection molding system includes a program control section installed outside injection molding machines. The program control section includes a program file section that stores a plurality of different programs in the form of files, and a program transfer section that selects a computer program from the program file section and transfers the selected computer program to the controller of an arbitrary injection molding machine when the arbitrary injection molding machine is operated. Only when an injection molding machine is operated, a program (control program) for operating the injection molding machine is selected from the program file section of the program control section, and the thus-selected program is transferred to the corresponding controller by the program transfer section.

Abstract: A temperature control unit for an injection molding machine having a control thermostat capable of detecting the temperature of a fluid flowing out of dies, wherein plural injection unit thermostats are coupled to the control thermostat. A heating/cooling dual control thermostat is provided for detecting the temperature of the fluid flowing into the dies and the heating/cooling dual control thermostat is coupled to the control thermostat in a cascade connection, whereby an injection unit temperature control system and a die temperature control system are connected via a communication line. The resulting temperature control unit has a simplified construction for temperature control and has reduced cost, while improving operability and maneuverability thereof. By cascade-controlling the die temperature, highly stabilized temperature control may be realized.

Abstract: A method of setting molding conditions for an injection molding machine 1 using a mold 2 whose specifications data are unclear included three setting processes. In the first setting process A, by inputting known data into controller 3, the molding conditions based on a data base prepared in advance and said input known data are set. In the second setting process B, injection molding is performed according to prescribed molding conditions pre-selected concerning injection pressure P, injection speed V and the injection start position of screw 4, and then, based on the product just molded, injection pressure P is altered, to set said altered injection pressure P, injection speed V and proper pre-feed measurement value Md as molding conditions. In the third setting process C, injection molding is performed according to molding conditions obtained from said second setting process B, and subsequently, taking into account the findings from the product just molded, said molding conditions are adjusted.

Abstract: When collecting data in connection with operational physical values from a plurality of injection molding machines by means of a direct numerical control computer system incorporated in an LAN, for example, when collecting a quality control data, the direct numerical control computer system is allowed to specify a collection starting time and a collection terminating time of the data for the respective injection molding machines. With reference to the condition thus specified the data is communicated to the direct numerical control computer system from the respective injection molding machines.
