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.

A method of controlling and/or regulating an injection molding of a mass through measurement of temperature in an injection molding tool of an injection molding machine, the injecting molding including providing an injection molding tool with a bore, and a mold pocket with a surface, subjecting the tool to a temperature and a mass to be injection molded to a temperature, cyclically injecting the mass into the mold pocket so as to thereby produce temperature jumps in the mold pocket, the method comprising the steps of: feeding only one thermosensor into the bore of the injection molding tool to a position between 1 mm and 2 mm inclusive from the mold pocket surface; recording the temperature jumps through the thermosensor so as to produce measurement results; monitoring the measurement results with respect to predetermined maximum permissible temperature deviations; using the measuring results to control the mass temperature and the tool temperature, the step of monitoring the measurement results including monitoring a minimum temperature Tmin and a temperature difference Dmax-Tmin, the step of using the measuring results including using the minimum temperature Tmin to regulate the tool temperature and using the temperature difference D
