The present invention pertains to an injection molding mold that can extrude the entirety of a workpiece from a cavity even when the cavity is enlarged so as to extend further than the outer side of an ejector plate. The injection molding mold may include a mold member having a cavity formed on the front side, a mold frame supporting the mold member from the back side, an ejector plate provided in the space within the mold frame so as to ascend and descend freely therein, a first workpiece extrusion means for extruding the workpiece above the ejector plate, and a second workpiece extrusion means for operating in conjunction with the first workpiece extrusion means and extruding the workpiece formed in the cavity in an area that is further to an outer side than the ejector plate.

An injection molding system including an injection nozzle that injects resin into a mold and a conveying device that conveys the injection nozzle between a first position where the injection nozzle injects resin into a first mold and a second position where the injection nozzle injects resin into a second mold.

According to one embodiment, a mold includes a substrate clamping surface, a cavity, a suction part, a vent, an intermediate cavity, and an opening/closing part. The substrate clamping surface contacts a surface of a processing substrate. The cavity is recessed from the substrate clamping surface. The suction part is recessed from the substrate clamping surface. The vent is provided on a path between the cavity and the suction part, communicates with the cavity, is recessed from the substrate clamping surface to a vent depth. The intermediate cavity is provided between the vent and the suction part on the path, communicates with the vent, and is recessed from the substrate clamping surface to an intermediate cavity depth deeper than the vent depth. The opening/closing part opens and closes the path and is provided between the intermediate cavity and the suction part on the path.

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.
