Abstract

An injection molding machine which includes a mold clamping device (20) that opens and closes a mold (90) and clamps the closed mold, an injection device (30) that injects a material into the clamped mold, and an ejecting device (21) that ejects a molded product (100) molded in the mold is provided. The injection molding machine further includes a plurality of cameras (2) that photograph the injection molding machine to generate image data, a memory (6) that records the image data, an input device that sets at least one photographing time by selecting the start or end of each process in a molding cycle, and a control device that controls the camera to photograph the injection molding machine at the at least one photographing time, and controls the memory to record the image data.

An injection molding machine, comprising a mold clamping device that opens and closes a mold and clamps the closed mold, an injection device that injects a material into the clamped mold, and an ejecting device that ejects a molded product molded in the mold,

wherein the injection molding machine further comprises a plurality of cameras arranged to photograph the injection molding machine,
a memory,
a display device, and
a control device that causes the display device to display a selection screen for selecting at least one photographing time from a plurality of photographing times, controls the camera to photograph the injection molding machine at the at least one photographing time to generate data of an image, controls the memory to record the data of the image, and causes the display device to display the data of the image, wherein
the plurality of photographing times are selected from a group of following times:
start of a mold closing process in which the mold clamping device closes the mold,
end of the mold closing process,
start of a mold clamping process in which the mold clamping device tightens the closed mold,
end of the mold clamping process,
start of a weighing process in which the injection device weighs the material,
end of the weighing process,
start of an injection process in which the injection device injects the material into the mold,
end of the injection process,
start of a pressure holding process in which the injection device maintains a holding pressure with respect to the material in the mold,
end of the pressure holding process,
start of a cooling process in which the material in the mold is cooled and solidified as the molded product,
end of the cooling process,
start of a mold opening process in which the mold clamping device opens the mold,
end of the mold opening process,
start of an ejecting process in which the ejecting device ejects the molded product formed in the mold, and
end of the ejecting process.
