Title:
MEASUREMENT SENSOR FOR INFORMATION REGARDING INSIDE OF MOLD
Document Type and Number:
WIPO Patent Application WO/2011/115276
Kind Code:
A1
Abstract:
Disclosed is a sensor which detects information from a die-casting mold and which determines the quality of a molded product. The sensor detects the gas pressure within a cavity by being provided with: a rod-shaped casing which can be attached to an attachment hole that is drilled on a molding die and that opens to the cavity; a porous filter which is disposed on the tip of the rod-shaped casing, has a tip surface that can conform to the mold cavity surface, and which can separate gas from a melt; an introduction chamber to which the cavity gas is introduced from the porous filter; and a gas pressure sensor which detects the pressure within the gas introduction chamber. The sensor detects the melt pressure within the cavity by being provided with: a pressure transmission rod which is inserted into the rod-shaped casing, can move along the axial direction thereof, and has a tip surface that can conform to the mold cavity surface; and a pressure sensor which faces the rear end of the pressure transmission rod and is fixed and held thereto. Moreover, the sensor detects the melt temperature within the cavity by being provided with a temperature sensor which is attached to a small hole formed on the center of the pressure transmission rod, and which comprises a thermocouple that has a detecting end disposed on the small hole on the side of the tip of the rod.
