Pressure measuring device for an injection molding machine

摘要

A pressure measuring device for an injection molding machine, includes a stroke drive mechanism operatively connected to a plasticizing unit of an injection molding machine, a force transmission member elastically deforming in response to an axial force and having one side facing the drive mechanism and another side facing the plasticizing unit. Each side of the force transmission member has at least two elevated supports, wherein the supports on one side are positioned in offset relationship to the supports of the other side. A sensor element is provided to measure a bending deformation of the force transmission member in a peripheral area thereof between two supports of the force transmission member for determining the injection pressure.
