PROBLEM TO BE SOLVED: To provide a mold clamping mechanism, which can be applied to a molded item which cannot be molded by an injection compression molding method. SOLUTION: A sprue bush 7 is fixed to a fixing side die mount plate 6 and the forward end of the bush 7 is inserted into a fixing plate 8 to make slidable the plate 8, as a fixing side die movable plate, with respect to the plate 6. A movable side die 9, comprising a female side cavity plate 91 and a male side cavity plate 92, is made slidable with respect to the plate 8, and the plate 6, plate 8, and die 9 are put into a mold clamping mechanism after the completion of clamping of the die, where there is no mold clamping force or a little mold clamping force. And an open/closure valve 5 is opened to feed molten resin into s sprue 72 from a nozzle 41, thereby storing the resin in the forward end of the bush 7, and simultaneous with the completion of feed of the resin, the valve 5 is closed to generate a high injection pressure in the mechanism, whereby the resin stored in the end of the bush 7 is filled into a molded item cavity 13. |
