Abstract

PURPOSE:To obtain sure feeder effect and to form a product without any flaw by arranging valve means shutting out communication with biscuit part in runner part in die apparatus and also arranging a feeder rod projected in the runner part. CONSTITUTION:The feeder rod 40 and plugging rod 42 can project in the runner part 28, respectively, and the plugging rod 42 can shut out the communicating hole from the biscuit part 30 to the runner part 2A at the time of projecting. After perfectly filling up molten metal in cavity 26 in the die apparatus by ascending plunger tip 70 in an injection cylinder, by advancing the plugging rod 42, the communicating hole between the runner part 28 and the biscuit part 30 is plugged. After that, the feeder rod 40 is pushed in the runner part 28. As the molten metal in the runner part 28 plugs the path of retreat with the plugging rod 42, the whole pressure received from the feeder rod 40 is transferred into the cavity 26 and sure feeder effect can be obtd.
