Abstract:
1. A mold monitoring apparatus for an injection molding machine, comprising: a light emitting unit configured to project light rays other than visible light rays onto a cavity portion of an opened mold; an image capturing unit including an image sensor configured to capture reflection light rays that travel from the cavity portion to the image sensor via a filter configured to block visible light rays; and an image processing unit configured to determine a state of the cavity portion on the basis of an image signal output from the image sensor and through image processing, wherein the image capturing unit captures regular reflection light from the cavity portion, wherein the image signal includes a plurality of pixels, wherein the light emitting unit is attached to a first side surface of the stationary platen of the mold clamping apparatus, wherein the image capturing unit is attached to a second side surface of a stationary platen of a mold clamping apparatus, and wherein the image capturing unit includes a support mechanism attached to the second side surface of the stationary platen and having a position adjustment section for adjusting the position of a main body of the image capturing unit along a longitudinal direction of the image capturing unit.
