<p>The molten resin plasticized in the plasticization chamber is fed to the injection chamber, where it is measured through the connection passage, and before it is injected by the plunger, the connection passage is blocked and the molten resin is preliminarily compressed. This invention provide the injection method of the preplasticization type injection molding machine that controls the volume of the filled molten resin with little variation as well as that of measured one , utilizing this blocking and preliminary compression. With blocking or preliminary compression, the position movement by which the plunger moves from the position at which the measurement is completed is calculated, and the position at which the next measurement will be completed is corrected. Furthermore, the molten is filled on the basis of the position of the plunger detected at the time of the preliminary compression. <IMAGE></p> |
