Title:
INJECTION MOLDING MACHINE WITH DISPLAY GRAPHING METERING AND KNEADING CONDITIONS
Document Type and Number:
WIPO Patent Application WO/1986/005741
Kind Code:
A1
Abstract:
Display for an injection molding machine, characterized in that it is formed so that set values of the metering and kneading conditions can be graphed on a CRT picture frame (20) so as to easily discover errors in the set conditions, including the number of revolutions per minute, back pressure and switching position, which are used during metering and kneading operations, of a screw. The number of switching steps in the metering and kneading treatment, and a back pressure, the number of revolutions per minute of a screw and a position to which the screw is to be switched in each switching step are set through a keyboard (21) and stored in a memory (15). A microcomputer (14) is adapted to discriminate a maximum value of each of the back pressures, the numbers of revolutions per minute of the screw and positions to which the screw is to be switched, and determine the scale factors for the back pressure, revolution number and screw position on the basis of the discriminated maximum values referred to above. The relation between a screw position and its back pressure and the relation between a screw position and the number of revolutions per minute of the screw are displayed on the CRT picture frame (20) on the basis of the scale factors corresponding to the set back pressure, the set number of revolutions per minute of the screw and the set position in which the screw is to be switched in each step.
