A molding machine is provided with a basic information setting function unit for setting basic information including resin data relating to pellet material, screw data relating to screw, and molding condition data relating to molding conditions, computation processing function unit comprising a provisional plastication time computation processing unit for calculating a provisional plastication time from the basic information, a melt film heating amount computation processing unit for calculating a heating amount of a melt film from the provisional plastication time obtained from the provisional plastication time computation processing unit, and a plastication delay time conversion processing unit for converting the heating amount of the melt film obtained from the melt film heating amount computation processing unit into a plastication delay time, and an output function unit for outputting plastication delay time or plastication information obtained based on the plastication delay time.

A control device for an injection molding machine is equipped with a pressure acquisition unit that acquires a pressure of a resin inside a cylinder, a reverse rotation control unit that causes a screw to be rotated in reverse based on a predetermined reverse rotation condition so as to reduce the resin pressure after having moved the screw rearward to a metering position, a compensation amount calculation unit that calculates a compensation amount to be made with respect to the reverse rotation condition, based on the resin pressure inside the cylinder acquired by the pressure acquisition unit when the reverse rotation of the screw is stopped, and a predetermined compensation function, and a compensation processing unit configured to compensate the reverse rotation condition based on the compensation amount calculated by the compensation amount calculation unit.

An injection molding machine management system includes an injection molding machine, a storage section that stores mold identification information and material identification information, an information input section that is configured to input molded product information, material information, and mold information, a determination section that determines whether or not a mold and a material to be used are an appropriate mold and an appropriate material in correspondence to a molded product to be molded; and a display section that performs display based on a determination result in the determination section, in which the determination section determines whether or not the mold and the material are appropriate in correspondence to the molded product to be molded by using the material information, the mold information, the mold identification information, and the material identification information based on the molded product information, and the display section displays a mold replacement time and a material replacement time required to replace the mold and the material when the determination section determines that the mold and the material are not appropriate in correspondence to the molded product to be molded.

A controller for an injection molding system is in communication with a melt flow control unit, a gas assist control unit, and a gas counter pressure control unit. The controller can effect real-time adjustments to gas assist pressure and/or gas counter pressure as a function of melt pressure or flow front position.

In the present invention, constructed is a highly reliable system that does not allow unforeseen conditions to occur in the remote diagnosis of a clamp device. All combinations of status of a state detection switch mounted on a clamp device are anticipated in advance by a recursive method, and the states are defined with no omissions. A control unit 9 includes: a main body memory 9c that stores the ON/OFF state of a state switch together with the status of an injection molding machine main body, the clamp status and time information; and a main body communication unit 9d which is capable of short-range wireless communication. A message diagnosing a failure is stored in a smartphone 12 for all combinations of the ON/OFF state of the state detection switch for each of the following cases: whether in mold replacement mode or not; and whether a clamp device is in a clamped state or an unclamped state, or in a state other than the forgoing. The history of the ON/OFF state of the state detection switch with respect to the status of the main body and the clamp status is read from the main body memory 9c by wireless communication, and a corresponding message is displayed.

A plasticizing device includes a plasticizing cylinder and a plasticizing screw arranged in the plasticizing cylinder. The plasticizing screw is rotatable about, and linearly movable along, a longitudinal axis. The plasticizing screw comprises a functioning section. A sensor is arranged in or on the plasticizing cylinder, and a distance to the surface of the functioning section of the plasticizing screw can be measured by the sensor. A detecting device can detect a type of the functioning section and/or an operating state of the functioning section, can detect a distance signal progression by a movement of the functioning section relative to the sensor, can compare the detected distance signal progression with a stored distance signal progression, and can issue a signal representing the type of functioning section and/or the operating state of the functioning section depending on a matching of the detected distance signal progression with a stored distance signal progression.
