Monitoring device of an injection mold of pieces made of thermoplastic for the detection of the piece or pieces of work and the state of the surface of the mold

摘要

The monitoring device of the invention includes, in a wall of a part 3 of the injection mould, at least one sensor 12, 15 connected via 16 to a processing device. This sensor is of the optical type and is used in conjunction with a light source. These sensors make it possible to detect the presence of a non-ejected component or of parts of this component which could remain bonded to the mould after ejection of the body of the component. IMAGE
