mold clamping force adjustment method and mold clamping force adjustment device for an injection molding machine

摘要

mold clamping force adjustment method for an injection molding machine, comprising:Closing of a mold, by means of a mold clamping mechanism, based on a set mold clamping force to produce a mold clamping force, injection of a molten resin in the mold, by means of a injection mechanism, extraction of a maximum of the actually mold clamping forces exerted on the mold, which, during the injection process of the molten resin are detected, as a maximum of the detected mold clamping force with respect to the adjusted mold clamping force, if the maximum is greater than the adjusted mold clamping force;Determining a plurality of data via the maximum of the detected mold clamping force with respect to the set mold clamping force by means of at least twice to extraction of the maximum of the detected on the basis of the mold clamping force mold clamping forces, which are set different;Determining an expression that the relationship between the set mold clamping force and the maximum of the detected mold clamping force with the data concerning the maximum of the detected mold clamping force with respect to the set mold clamping force; andDetermining a set as a suitable mold clamping force value mold clamping force value in such a way that the set mold clamping force and the corresponding maximum of the detected mold clamping force in the determined relational expression are the same.
