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.

Provided is an injection molding apparatus including a first mold and a second mold, an ejector plate provided on the first mold to reciprocate and configured to eject an injection molded object between the first mold and the second mold, and a sensor device having a moving sensor detachably attached to the ejector plate, and configured to detect a position of the ejector plate, wherein the sensor device is detachably attached to the first mold and the ejector plate by a magnetic force.

There is provided a mold conveying guide device for use in replacement of a mold by conveying the mold into and out of a mold fixing position in an injection molding machine. A connecting arm is attached to the mold and projects in a direction in which the mold is conveyed into the mold fixing position. A guide roller is rotatably supported at a tip end portion of the connecting arm. The guide roller is configured to rotate while being in contact with a mold attaching surface of at least one of a fixed platen and a movable platen, and configured to guide the mold such that the mold can come close to or move away from the at least one of the fixed platen and the movable platen.

A computer-implemented simulation method for use in a molding process by a computer process is disclosed. The method includes steps of specifying a simulating domain comprising a mold cavity and a barrel of an injection machine, wherein the barrel is configured to connect to the mold cavity; creating at least one mesh by dividing at least part of the simulating domain; specifying boundary conditions of the mesh by taking into consideration at least one motion of a screw in the barrel; and simulating a first injection-molding process of a molding material by using the boundary conditions to generate a plurality of molding conditions.

A mold clamping device of an injection molding machine includes a mold clamping shaft fixed to a movable platen, a mold clamping ram to press the mold clamping shaft against a fixed platen, a ram position detecting member that detects a position of the mold clamping ram, an encoder detecting a position of the movable platen, a ram position control member that hydraulically controls a position of the mold clamping ram, a storage unit storing a difference value of mold closing positions of the movable platen before and after mold replacement, and a control unit. The control unit calculates the difference value when mold thickness adjustment is performed, calculates a movement position of the mold clamping ram based on a current position of the mold clamping ram and the difference value, moves the mold clamping ram to the movement position, and stops the mold clamping ram to perform mold clamping.
