A safety apparatus includes a safety bar that is capable of moving in a mold clamping direction and a mold opening direction, in conjunction with a moving platen provided with a movable mold, and a latch that contacts the safety bar when a door, which is provided in a cover of an injection molding device, is open, wherein the latch includes a notch in a surface thereof on the mold-opening-direction side.

An apparatus and method for actuating a valve stem between an open position and a closed position and for taking one or more valve gated nozzle out of service is disclosed. The hot runner includes a valve gated nozzle having a valve stem, the valve stem coupled to a piston that is held against an actuation plate via pressurized air. When a valve stem becomes stuck in a gate of the hot runner, the actuation plate can continue to move while the piston remains stationary. The valve stem may also be protected from an over force situation such as if the valve stem encounters an obstruction as the actuation plate is moving toward the closed position.

In an injection molding system, a molded part transport apparatus and a worker share an area to perform cooperative work. When a molded part check mode is valid, conforming product identification inspection of a molded part is performed in an area where the worker works, and molded part sorting means sorts the molded part on the basis of a result of the inspection. As a result, the conforming product identification inspection of the molded part can be performed and the molded part can be sorted with the safety of the worker is maintained.

The management system has an injection molding machine and a management unit for managing the injection molding machine, wherein the management unit includes: a plurality of physical quantity measurement units configured to be provided at a plurality of movable parts included in the injection molding machine; an ascertainment unit configured to calculate, based on a plurality of physical quantity data respectively measured by the plurality of physical quantity measurement units, a comparative relationship representing a relational state of the plurality of physical quantity data between the plurality of the movable parts, and to ascertain whether the comparative relationship deviates from a preset reference comparative relationship; and an alarm unit configured to issue an alarm when the ascertainment unit ascertains that the comparative relationship deviates from the reference comparative relationship.
