ABSTRACT:
A diecasting machine includes a transverse member; a column passing through the transverse member; and a column nut mounted on the column and having an underface being in a face-to-face engagement with a surface area of the transverse member. The column nut applies, with its underface, pressure forces on the surface area of the transverse member. Such pressure forces are derived from forces generated in the diecasting machine, taken up by the column and transmitted by the column to the column nut. The transverse member has a measuring bore which is situated adjacent the surface area of the transverse member and which has an axis oriented transversely to the length dimension of the column. A measuring plug is accommodated in the measuring bore for detecting the pressure forces applied to the surface area by the underface of the column nut and for emitting signals representing magnitudes of the pressure forces. A regulating device receives the signals from the measuring plug for regulating diecasting operations of the diecasting machine as a function of the signals.
