Abstract

A mold for use with an injection molding machine includes a body having a surface and a ring protruding from the surface for aligning the body and a platen. The ring defines a right circular cylinder having a protruding end, the protruding end having subtracted therefrom a generally wedge-shaped portion, the protruding end forming a tapered end.

First claim

The invention claimed is:

1. A mold for use with an injection molding machine comprising:
a body having a surface;
a ring protruding outward from the surface for aligning the body and a platen, the ring including a tapered end; wherein the ring defines a right circular cylinder bounded by a body planar surface and a parallel plane spaced from the body planar surface, the ring having a protruding end, the protruding end having subtracted therefrom a generally wedge-shaped portion forming said tapered end and the tapered end having a first region extending furthermost from the surface of said body, the wedge-shaped portion defined by an angled plane which is coincident with the first region of the tapered end of the ring, the first region positioned at a periphery of the ring, the angled plane extending from the first region to a second region positioned at the periphery of the ring, the angled plane subtending at an acute angle from the spaced parallel plane;
wherein in response to the tapered end of the ring of the mold being positioned in partial alignment with an opening of the platen such that at least a portion of the tapered end is inserted inside of the opening, and a continuous force applied to the mold toward the opening, and the tapered ring being incrementally moved toward a center of the opening, the tapered end guiding the ring into full engagement with the opening.

2. The mold of claim 1 , wherein the ring is configured such that the entire tapered end is insertable inside of the opening.

3. The mold of claim 1 , wherein the tapered end has a planar surface.

4. The mold of claim 1 , wherein at least a portion of the tapered end has a curved surface.

5. The mold of claim 1 , wherein the region is positioned at one of an uppermost portion and a lowermost portion of the tapered end;
wherein in response to the tapered end of the ring of the mold being positioned in partial alignment with the opening of the platen such that at least a portion of the tapered end is inserted inside of the opening, and a continuous force applied to the mold toward the opening, and the tapered ring being incrementally moved vertically toward the center of the opening, the tapered end guiding the ring into engagement with the opening.
