Abstract
PURPOSE: To obtain a proper molding continuously by regulating working oil and heat medium in the manufacture of a plural number of resin moldings by using molds with plural cavities.
CONSTITUTION: Using the mold 1 with plural cavities 3a, 3b, and 3c, plural resin moldings are injected concurrently. In this case, the pressure and flow rate of the working oil to be supplied to an injection cylinder 6 are controlled in such a way that the rising gradient of filling pressure in the filling process of molding resin into one cavity (or the main cavity, e.g., 3b) chosen as the main control target and also the falling gradient of pressure in the pressure-keeping process are kept at given set values. At the same time, for the other cavities 3a and 3c, for example, the value of the falling gradient of pressure kept in the pressure-keeping process is continuously measured, and when the measured value exceeds an allowable set value, the flow rate of heat medium to the other cavities 3a and 3c, for example, is regulated.
