Abstract
An apparatus to sense temperature in a glassware forming machine. A mold body includes an exterior surface, a mold cavity having an interior mold surface, and a blind hole having a closed end including a closed end surface adjacent to and spaced outwardly from the interior mold surface, wherein the blind hole extends outwardly from the closed end surface toward the exterior surface. The mold body is removably carried on a mold hanger, and a light collector is carried by the mold hanger to collect infrared light emitted within the blind hole.
Claims18
Apparatus to sense temperature in a glassware forming machine, comprising:
- a mold body including a longitudinally extending inboard axis, an inboard side, an outboard side, a lower end, and an upper end, a hanger recess at the outboard side, an exterior surface, a mold cavity having an interior mold surface, and a blind hole having a closed end including a closed end surface adjacent to and spaced outwardly from the interior mold surface, wherein the blind hole extends outwardly from the closed end surface toward the exterior surface and includes an open end in the outboard side of the mold body within the hanger recess;
- a mold hanger on which the mold body is removably carried, wherein the mold hanger is at least partially carried in the hanger recess of the mold body and includes an inboard side, an outboard side, a lower end, and an upper end, and a hanger hole that extends between the outboard side and the inboard side and is aligned with the blind hole of the mold body;
- and
- a light collector carried by the mold hanger to collect infrared light emitted within the blind hole.
A glassware forming apparatus that includes:
- a glassware mold body including a longitudinally extending inboard axis, an inboard side, an outboard side, a lower end, and an upper end, a mold cavity in the inboard side for forming a glassware article, and a blind hole in the glassware mold body extending outwardly toward an exterior surface of the mold body from a closed end surface of the blind hole adjacent to an interior surface of the mold body cavity;
- a mold hanger disposed at the outboard side of the mold body and on which the mold body is removably carried and including an inboard side, an outboard side, a lower end, and an upper end, and a hanger hole extending between the outboard side and the inboard side in alignment with the blind hole of the mold body;
- and
- a pyrometric apparatus including a pyrometer, and a light collector at least partially disposed in the hanger hole to collect infrared light from the blind hole for transmission to the pyrometer.
