Abstract

PURPOSE: To mold efficiently a molded product of a long-sized matter while contriving miniaturization and weight reduction of an injection device, by a method wherein after the first movable mold and a single stationary mold are clamped down on each other by confronting them with each other by following a movement of a movable member and synthetic resin is injected within a molding space between the first movable mold and stationary mold with the first injection device.
CONSTITUTION: When a mold clamping cylinder is actuated, the second movable mold 23 is clamped down a stationary mold 25 holding the first molded product 41. In this instance, the first molded product 41 is positioned within the second molding space 47 formed of the second movable mold 23 and stationary mold 25. Then when the second injection stand is moved toward the rear of the stationary mold 25 with the actuating second cylinder 31, an injection nozzle of the second injection device 29 is pressure-contacted to a sprue 49 of the stationary mold 25. Then when molten synthetic resin is injected within the molding space 47 through the injection nozzle of the second injection device 29, the second molded product 51 is molded while the same is being fused integrally with the first molded product 41 and a product 53 is molded.
