METHOD FOR MONITORING AND/OR REGULATING INJECTION CASTING OPERATIONS IN INJECTION CASTING MACHINES

PCT No. PCT/DE85/00219 Sec. 371 Date Mar. 11, 1986 Sec. 102(e) Date Mar. 11, 1986 PCT Filed Jun. 28, 1985 PCT Pub. No. WO86/00563 PCT Pub. Date Jan. 30, 1986.A method is suggested which is used for controlling and/or regulating of the injection molding in injection molding machines by measuring the temperature in the injection tool. A thermosensor is fed within a bore in the tool very closely to the molding pocket surface, so that the temperature fluctuations resulting from the injection cycles can be registered by the thermosensor. The measuring results are controlled with respect to maximum permissible deviations, whereby it is advantageous to control the minimum temperature and the temperature difference between the maximum and the minimum temperature. When exceeding predetermined maximum permissible deviations a signal is actuated for controlling a quality control for sorting out of parts and/or a light signal or an acoustic signal and/or the machine is switched off. Moreover, the measuring signals are used for controlling of the tool temperature and the mass temperature. Each molding pocket is controlled with respect to a complete filling when using multiple pocket molds.
