Abstract
A temperature correction apparatus 1 of an injection molding machine for correcting detected values D.sub.2 . . . obtained from a plurality of thermostats 2 . . . set to an injection molding machine M and/or command values S.sub.2 . . . for performing temperature feedback control in accordance the detected values D.sub.2 . . . , comprising a correction constant computing section 11 for correcting first correction constants P.sub.2 . . . for the detected values D.sub.2 . . . and/or second correction constants Q.sub.2 . . . for the command values S.sub.2 . . . in accordance with detected values Di and Dj of the thermostats 2 . . . under different temperature conditions Ti and Tj and reference values Ei and Ej corresponding to the temperature conditions Ti and Tj, a storage section 12 for storing the obtained first correction constants P.sub.2 . . . and/or second correction constants Q.sub.2 . . . , and a correction computing section 13 for correcting the detected values D.sub. 2 . . . and/or command values S.sub.2 . . . in accordance with the stored first correction constants P.sub.2 . . . and/or second correction constants Q.sub.2 . . . , in order to accurately detect temperatures by eliminating the absolute error of each thermostat and the relative error between the thermostats and precisely and accurately perform the entire temperature control.
