Abstract
A method and an apparatus for measuring the closing and holding force on the moulding die or tool (6, 7) of a pressure diecasting or injection moulding machine of which the closing device comprises a toggle lever mechanism. Measurement of the closing and holding force takes place by way of measuring a deformation of that end plate (4) on which the bars (1) and the toggle lever mechanism (10) are supported. The bars (1) and the toggle lever mechanism (10) transmit to the end plate (4) forces which produce a bending moment. The bending moment leads to a comparatively large deformation which is therefore readily measured by a measuring device (14, 24) associated with the end plate. By arranging the measuring device (14, 24) at the end plate (4), one also avoids damage to the measuring device (14, 24) by the movable parts of the closing device and access to the pressure diecasting or injection moulding machine by the operator is not impeded (FIG. 1).
