Abstract
An apparatus, mounted to a mold, for injecting air into a mold cavity and removing exhaust from the mold cavity, comprising: a blow cylinder body block mounted to the mold having a conduit to the mold cavity, wherein the blow cylinder body block comprises an insulator and the conduit has walls; a needle passing through the blow cylinder body block and the conduit, wherein the needle is connected to a piston, wherein the needle has a needle passage, and wherein compressed air is applied to the piston to extend the needle into the mold cavity and retract the needle from the mold cavity; and an insulator between the needle and the conduit walls.

An apparatus, mounted to a mold, for injecting air into a mold cavity and removing exhaust from the mold cavity, comprising:
- a blow cylinder body block mounted to the mold having a conduit to the mold cavity, wherein the blow cavity body block comprises a first insulator and the conduit has walls;
- a needle passing through the blow cylinder body block and the conduit, wherein the needle is connected to a piston, wherein the needle has a needle passage, and wherein compressed air is applied to the piston to extend the needle into the mold cavity and retract the needle from the mold cavity;
- and
- a second insulator between the needle and the conduit walls.
An apparatus, mounted to a mold, for injecting air into a mold cavity and removing exhaust from the mold cavity, comprising:
- a blow cylinder body block mounted to the mold having a conduit to the mold cavity, wherein the conduit has walls;
- a needle passing through the blow cylinder body block and the conduit, wherein the needle is connected to a piston, wherein the needle has a needle passage, and wherein compressed air is applied to the piston to extend the needle into the mold cavity and retract the needle from the mold cavity;
- and
- a first insulator forming a layer on the conduit walls.
An apparatus, mounted to a mold having a mounting surface, for injecting air into a mold cavity and removing exhaust from the mold cavity, comprising:
- a spacer;
- a blow cylinder body block mounted to the mold through a spacer forming an air gap between the mounting surface and the blow cylinder body block, wherein the mold has a conduit to the mold cavity and wherein the conduit has walls;
- a needle passing through the body and the conduit, wherein the needle has a needle passage, and wherein compressed air is applied to the piston to extend the needle into the mold cavity and retract the needle from the mold cavity;
- and
- an insulator between the needle and the conduit walls.
