PURPOSE:To mold a product of high quality by extruding a melt into between a movable mold and a fixed mold after the melt is poured into a groove section formed in the center of the movable mold and then compressing the melt while the movable mold is actuated. CONSTITUTION:The distance between a moving platen 26 and a floating platen 30 is adjusted as l1 by driving cylinders 32a and 32b in a mold. Next, the distance between the joining faces of a movable mold 38 and a fixed mold 40 is adjusted as l2. Then, a melt A is injected from a gate 49 of a fixed platen 22 into a cavity 46 and stored in a groove section 50. A mold clamping cylinder 14 is driven while the cylinders 32a and 32b in the mold are open, and when the moving platen 26 is displaced by the distance l1, the melt A stored in the groove section 50 is flowed into the cavity 46. Said melt A is compressed by a male mold 42 of the movable mold 38 and a movable core 52 by moving the movable plate 26 toward the fixed platen 22 while the cylinder 14 is actuated and further displacing the movable plate, and the peripheral end of the cavity 46 corresponding to a side face section Wb of a product W is filled with molten hot water. |
