Device for measuring pressures in a mold cavity of a casting mold that can be filled with melt, particularly a vacuum die-casting mold

摘要

A device for measuring pressures in a mold cavity of a casting mold that can be filled with melt, particularly a vacuum die-casting mold, includes a pressure sensor, a measurement channel, and a ring-shaped gap that runs in the axial direction between an inner body and an outer body disposed axially in the inner body. The ring-shaped gap stands in connection with the mold cavity at its one end and in connection with one end of the measurement channel at its other end. The pressure sensor is disposed at the other end of the measurement channel.

主权项

1. A device for measuring pressures in a mold cavity of a casting mold fillable with melt comprising:
(a) a pressure sensor; (b) a measurement channel having first and second measurement channel ends; (c) an inner body; (d) an outer body disposed axially to the inner body; and (e) a ring-shaped gap running in an axial direction between the inner body and the outer body; wherein the ring-shaped gap has a first end adapted to stand in connection with the mold cavity and a second end connected with the first measurement channel end; and wherein the pressure sensor is disposed at the second measurement channel end.
