Abstract

PURPOSE: To operate with simple structure and high reliability by opening and closing a nozzle gate of a hot runner nozzle with an opening and closing device planted and fixed in the hot runner nozzle.
CONSTITUTION: Molten material is supplied from the rear into a hot runner nozzle 2 in a pressurized state. A spindle 12 moves forward, opening a nozzle gate 9 as it closes tightly the front opening of a nozzle hole. Molten material reaches cavity 31 through a nozzle gate 9 from the hot runner nozzle hole, a penetrating hole 25 and a gate 28, etc. of a ring part 23. Molten material becomes solid in a required shape in these cavitites. Next, when the pressure on the molten material is stopped and decreased, the hot runner nozzle 2 itself recedes. The spindle 12 recedes as it is pushed by a spring 13 to close a nozzle gate 9. On the other hand, a front metal mold plate 13 moves together with the material solidified in a cavity 13, which is then separated to be a product.
