An injection molding system including an injection molding apparatus that performs injection molding, and a conveyor apparatus configured to insert a mold through an opening of the injection molding apparatus, wherein the improvement to the injection molding system includes the injection molding apparatus further comprising a first door configured to restrict access via a first opening when a first door is closed and a second door configured to restrict access via a second opening when a second door is closed, and a controller configured to start injection molding with the mold in a case where the first door is partially opened and the second door is closed.

A method of detecting and compensating for a non-operational mold cavity in an injection molding apparatus having a plurality of mold cavities and an injection molding screw or ram includes injecting, via the injection molding screw or ram, a molten thermoplastic material into the plurality of mold cavities. The method includes measuring a first process parameter of the injection molding apparatus at a pre-determined time during or after the injecting. The method also includes determining, based on the first process parameter, whether one or more mold cavities of the plurality of mold cavities are non-operational. Then, when it is determined that one or more mold cavities are non-operational, the method includes automatically adjusting the first process parameter or a second process parameter of the injection molding apparatus.

An operation quantity determination device for determining an operation quantity related to a molding machine, includes an observation unit configured to acquire observation data obtained by observing a physical quantity related to molding by the molding machine when the molding is executed, a state expression unit configured to generate a state expression map expressing a state of the molding machine based on the observation data acquired by the observation unit, and an operation quantity output unit configured to output the operation quantity based on the state expression map generated by the state expression unit.

Provided is an injection molding system that includes: a mounting position detection unit configured to detect a mounting position of a temperature control hose establishing connection from a mold temperature controller to a mold; and a temperature control hose attachment and detachment unit. Attachment and detachment of the temperature control hose is established by the temperature control hose attachment and detachment unit. By virtue of this feature, it is made possible to simplify the operator's tasks and achieve quick attachment and detachment of the temperature control hose in a short period of time.

An injection molding system comprising: a first selected valve, one or more downstream valves, delivering a fluid to a mold cavity, at least one fluid property sensor, each valve associated with a position sensor that detects opening of a gate at an actual open gate time to the controller, the controller automatically adjusting time of instruction to open the gates on a subsequent injection cycle by an adjustment time equal to any delay in time between a predetermined open gate target time and an actual open gate time, wherein the system forms a first one or more parts or objects, the user inspecting or measuring the first one or more parts or objects and manually adjusts the predetermined open gate target time.

An injection molding system comprising: a first selected valve, one or more downstream valves, delivering a fluid to a mold cavity, at least one fluid property sensor that detects a flow front of fluid material flowing downstream through the mold cavity at a trigger location within the cavity disposed between the first gate and at least one selected downstream gate, a controller instructing an actuator associated with the downstream gates to open the gates at a predetermined open gate target time on a first injection cycle, each valve associated with a position sensor that detects opening of a gate at an actual open gate time to the controller, the controller automatically adjusting time of instruction to open the gates on a subsequent injection cycle by an adjustment time equal to any delay in time between the predetermined open gate target time and the actual open gate time.

A production management system includes: an injection molding unit producing a molded product; and a control device. The injection molding unit includes: an injection molding machine molding the molded product by injection molding; a determination unit determining whether a number of the molded products to be produced is equivalent to a predetermined unit of production or not; and an operation information transmitting unit transmitting operation information of the injection molding unit when it is determined that the number of the molded products to be produced is equivalent to the predetermined unit of production. The control device includes an operation information receiving unit receiving the operation information transmitted from the operation information transmitting unit.

The present disclosure prevents load from being produced in an injection molding machine. The control device for an injection molding machine according to one embodiment of the present disclosure has a determining part that is configured to determine, based on information detected in accordance with a movement of a measurement motor provided in the injection molding machine, whether or not an operation of removing or attaching a screw that rotates in accordance with the measurement motor has been performed.

An injection molding system includes a plurality of inspection apparatuses for inspecting molded article quality, a unit that transports a molded article molded by an injection molding machine, a molded article containment unit that is provided for each of types of post-treatment operations needed for the molded article, a transport destination designation unit that selects and designates the molded article containment unit to contain the molded article on the basis of a combination of inspection results from the plurality of inspection apparatuses, and a molded article sorting and transport unit that sorts and transports the molded article into the molded article containment unit designated by the transport destination designation unit.

In an injection molding system, an insert formed with a cavity or an insert member for molding an insert-molded article is shot by a camera, and the insert or the insert member to be inserted into a mold is identified based on a characteristic of the insert or the insert member shot by the camera and previously stored data on the insert or the insert member.
