Abstract
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.
Claims27
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.
An assembly comprising:
- a casting mold comprising a first mold half and a second mold half, wherein the first mold half is a fixed mold half and the second mold half is a movable mold half or the first mold half is a movable mold half and the second mold half is a fixed mold half;
- and
- a device for measuring pressures in a mold cavity of the 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 disposed on the first mold half;
- (d) an outer body disposed on the second mold half 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 connected with the mold cavity and a second end connected with the first measurement channel end;
- and
- wherein the pressure channel is disposed at the second measurement channel end.
