Abstract

PURPOSE: To mass-produce continuously a multiple color molding in which the neighboring part of two colors has a mixed color of them by providing a nozzle including a dividing torpedo spreader between the runner of a molding die and plural heating injection cylinders.
CONSTITUTION: A nozzle 14 is formed to include a dividing torpedo spreader 15 which has separated passages (a), (b), (c), [notation (d) represents a torpedo liner], and is provided between three heating cylinders (not shown) and a die runner 9. Resins of different colors injected respectively from the three heating cylinders to the separated passages (a), (b), (c) of the torpedo spreader at the same speed join in a space (e) at the end of the nozzle 14 and are extruded to the runner 9, pass a branching dividing wall 10 and a fan-shaped passage 11, and while being spread, are filled from a runner 12 into a space 13, and thus a striped-pattern molding 17 of five colors consisting of three original synthetic resin colors (a'), (b'), (c') and the mixed colors of two.
