Abstract
A method produces an injection molded part. A plastic material is injected into a cavity for forming the injection molded part. The plastic material in a flow line region of the cavity, where the plastic material from two directions coincides during an injection molding process, is at least partially removed from the cavity via at least two overflow points and, in so doing, is locally swirled or mixed between the overflow points.
Claims7
An injection mold for producing an injection molded part, the injection mold comprising:
- a cavity formed therein for forming the injection molded part, wherein at least two tunnels are coupled as overflow points to a flow line region of said cavity such that, when a plastic material converges from two directions in said flow line region during an injection molding process, the plastic material flows out of said cavity via said tunnels and, as a result, the plastic material is locally swirled or mixed in said flow line region, wherein said at least two tunnels are disposed tangentially and axially offset from one another.
