Analysis support device for the molten state of resin

Abstract

This invention provides a visualization technology that can accommodate changes in the material of the screw and heating cylinder in an injection molding device. [Solution] The heating cylinder material and screw material can be manually selected on the operation screen 36. If there is a human error in the manual selection, the sub-display unit 37 will display the message, "The materials do not match. Please check."

Claims

1. A resin melting state analysis support device is provided in an injection molding apparatus having one heating cylinder from among several heating cylinders of different materials, a screw housed in the heating cylinder so as to be rotatable and axially movable, a screw rotation mechanism for rotating the screw, a screw movement mechanism for advancing the screw, and an operating panel for controlling the rotational speed of the screw rotation mechanism and the movement of the screw movement mechanism, and assists in the work of analyzing the melting state of the resin, The aforementioned screw is one of several screws made of different materials. The aforementioned analysis support device for the molten state of the resin is, The heating cylinder is equipped with an AE sensor that detects AE waves, The heating cylinder is equipped with a material-specific amplitude storage unit that stores a first resin-free amplitude calculated from the AE wave obtained without resin being introduced into the heating cylinder, for each combination of the heating cylinder material and the screw material. The heating element and the screw are provided with an operating screen that allows the user to manually select the material of the heating element and the screw. A resin melting state analysis support device characterized by comprising a calculation unit that calculates the first resin-free amplitude, obtains the resin-present amplitude from the AE wave detected by operating the injection device with the resin in place, obtains the first resin-free amplitude that matches the material of the heating cylinder and the material of the screw specified on the operation screen from the material-specific amplitude storage unit, and performs a process to delete the portion where the resin-present amplitude and the first resin-free amplitude match.

2. An analysis support apparatus for the molten state of a resin according to claim 1, The resin melting state analysis support apparatus is characterized in that the calculation unit obtains a second resin-free amplitude from an AE wave detected when the injection device is operated without the resin being injected, before obtaining a resin-present amplitude from an AE wave detected when the injection device is operated with the resin injected, and identifies whether or not this second resin-free amplitude corresponds to the first resin-free amplitude obtained from the material-specific amplitude storage unit.
