a body;
an upper guard arm extending from the body, wherein the upper guard arm is adapted for actuating a trigger on a mold locking mechanism, and
wherein the upper guard arm further comprises a movable guard arm portion, an integrally attached guard arm portion and a guard arm pin hole adapted for passage of a locking pin.
2. The safety device of claim 1 , wherein the body further comprises a lower guard arm and a middle guard arm.
3. The safety device of claim 1 , wherein the guard arm pin hole is formed by the movable guard arm portion and the integrally attached guard arm portion.
4. The safety device of claim 1 , wherein the movable guard arm portion has a first spring hole formed therein.
5. The safety device of claim 4 , wherein the integrally attached guard arm portion comprises a second spring hole formed therein.
6. The safety device of claim 5 , further comprising a spring located within the first and second spring holes.
7. A safety device for use with a blow molding apparatus comprising:
a body having a body hinge hole;
an upper guard arm extending from the body, wherein the upper guard arm is adapted for actuating a trigger on a mold locking mechanism,
wherein the upper guard arm further comprises a guard arm pin hole adapted for passage of a locking pin; and
wherein the upper guard arm further comprises a movable guard arm portion, wherein the movable guard arm portion further comprises a guard arm hinge hole.
8. The safety device of claim 7 , wherein a hinge is located within the body hinge hole and the guard arm hinge hole.
9. A safety device for use with a blow molding apparatus comprising:
a body including a handle;
an upper guard arm extending from the body, wherein the upper guard arm is adapted for actuating a trigger on a mold locking mechanism, and
wherein the upper guard arm further comprises a guard arm pin hole adapted for passage of a locking pin.
10. A safety device for use with a blow molding apparatus, comprising:
a body;
an upper guard arm extending from the body, wherein the upper guard arm is adapted for actuating a trigger on a mold locking mechanism, and
wherein the upper guard arm further comprises a guard arm pin hole adapted for passage of a locking pin, and wherein the body further comprises a lower guard arm and a middle guard arm and the lower guard arm and the middle guard arm each have “U” shaped openings.
11. A safety device for use with a blow molding apparatus comprising:
a body comprising;
an upper guard arm extending from the body, wherein the upper guard arm is adapted for actuating a trigger on a mold locking mechanism, and
wherein the upper guard arm further comprises a guard arm pin hole adapted for passage of a locking pin, the guard arm pin hole being tear drop shaped.
12. A safety device for use with a blow molding apparatus comprising:
a body comprising;
an upper guard arm extending from the body, wherein the upper guard arm is adapted for actuating a trigger on a mold locking mechanism, wherein the upper guard arm is adapted for passage of a locking pin, the upper guard arm further comprising a movable guard arm portion and an integrally attached guard arm portion;
a lower guard arm having a first opening; and
a middle guard arm having a second opening.
13. The safety device of claim 12 , wherein the upper guard arm further comprises a guard arm pin hole formed when the movable guard arm portion is in a closed position and adjacent to the integrally attached guard arm portion.
14. The safety device of claim 13 , further comprising a spring located within a first spring hole located on the movable guard arm portion and a second spring hole located on the integrally attached guard arm portion.
15. The safety device of claim 14 , further comprising a hinge located between the movable guard arm portion and the body.
