Cluster of arrow heads and a method of manufacturing the same
An arrow head cluster is created utilizing an injection mold. An upper cluster cavity is formed in an upper die member and a lower cluster cavity is created in a lower die member. The upper and lower cluster cavities, when joined create a cluster cavity. The cluster cavity is used to create the arrow head cluster, after molten material is injected into the injection mold. The cluster cavity includes a plurality of chambers for creating a plurality of arrow heads. The plurality of chambers are connected to each other with a plurality of flow channels and a support frame. The injected material includes metals, ceramic and plastic. The materials are injected into the cluster cavity through the plurality of flow channels. The plurality of flow channels allow the material to flow evenly through the plurality of cluster cavities.
1. An arrow head cluster comprising:
a cluster of a plurality of arrow heads joined with each other and a frame;
each arrow head includes a threaded section to threadably engage an end of an arrow; and
said frame retains said plurality of arrow heads with said frame as a single unit.
2. The arrow head cluster of claim 1 wherein:
said plurality of arrow heads are retained on said frame with a break away connection.
3. The arrow head cluster of claim 1 wherein:
said threaded section is external on the arrow head.
4. The arrow head cluster of claim 1 wherein:
said threaded section is internal in said arrow head.
5. The arrow head cluster of claim 1 wherein:
said cluster having at least two arrow heads.
6. The arrow head cluster of claim 1 wherein:
the threads of the arrow head are external and self-tapping.
7. An arrow head comprising:
an arrow head which includes a frontal section and an arrow head rear section, external self-tapping threads are formed on the arrow head rear section; and
said arrow head is created in a cluster of a plurality of arrow heads joined with each other and a frame.
