INJECTION MOLDING MACHINE AND OPERATOR SUPPORT METHOD
An injection molding machine includes a control device configured to output at least one set of operator support information. The operator support information includes a set of support target setting data and control target predicted amount of power. The support target setting data includes at least one piece of setting data configuring a molding condition. The control target predicted amount of power is a predicted amount of power consumption of a control target controlled in association with the support target setting data with respect to a change in the support target setting data.
INJECTION MOLDING MACHINE AND CONTROL DEVICE OF INJECTION MOLDING MACHINE
An injection molding machine includes: a cylinder that holds a molding material to be injected into a mold; a plasticizing member provided in the cylinder so as to be movable and rotatable; a temperature measurer that measures a temperature of the cylinder or of the mold; and a period setting unit configured to set a cold start prevention period, which is a period for restricting the injection of the molding material into the mold, based on the temperature measured by the temperature measurer until a temperature of the molding material or the temperature of the mold rises. The period setting unit stores temperature-time data in which the temperature measured by the temperature measurer is associated with time, and adjusts the cold start prevention period based on an actual temperature of the stored temperature-time data.
PLASTICIZING DEVICE
A plasticizing device includes a drive motor, a rotor that is rotated by the drive motor and has a groove formed face with a groove formed therein, a barrel that is opposed to the groove formed face and has a communication hole, a heating portion that heats a material in a pellet form supplied between the groove and the barrel, and a control unit that controls the drive motor and the heating portion so as to plasticize the material supplied between the groove and the barrel and cause the material to flow out from the communication hole. The heating portion has a first heating portion and a second heating portion disposed closer to the communication hole than the first heating portion, and the barrel has a first region and a second region that is closer to the communication hole than the first region. The control unit individually controls the first heating portion and the second heating portion so that a temperature of the second region is higher than a temperature of the first region.
TEMPERATURE CONTROL DEVICE, TEMPERATURE CONTROL METHOD, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM
In a temperature control device, a resin flow channel is formed from a nozzle section and a cylinder section that is connected to the nozzle section and the device controls the temperature of the resin that flows in the resin flow channel. The temperature control device is provided with: a first temperature sensor for detecting the nozzle temperature of the resin flowing through the nozzle section; a first temperature control unit for performing PID control so that the nozzle temperature achieves a first target temperature; multiple second temperature sensors for detecting the cylinder temperature of the resin flowing through the cylinder section; and second temperature control units for performing PID control so that the cylinder temperature achieves a second target temperature. The second temperature control units perform PID control of the cylinder temperature using temperature control information from the first temperature control unit.
Technology for monitoring an extruder or respectively an injection moulding machine

GAS SUPPLY DEVICE, INJECTION MOLDING MACHINE, AND FOAM MOLDING METHOD
An injection device (2) of an injection molding machine (1) includes a heating cylinder (18) having a gas introduction port (30) and a screw (19), and a gas supply device (5) is connected to the gas introduction port (30). The gas supply device (5) includes a gas supply source (33) and a gas pressure regulating unit (34). The gas pressure regulating unit (34) regulates a gas pressure and supplies the gas when a gas from the gas supply source (33) is introduced into the gas introduction port (30). Specifically, the gas pressure is caused to change in a molding cycle and is increased to a high pressure in a metering process (61). That is, a pressure increasing period (71) in which the gas pressure increases at least partially overlaps with the metering process (61).
