Abstract
A relay device and a pressure detection device are provided that are configured to eliminate the necessity of calibrating an output value from a pressure sensor in the pressure detection device even when a mold is replaced. A relay device for a pressure detection device provided with a pressure sensor (S1 to Sn) configured to detect an inner pressure in a cavity (CT) of a mold of an injection molding machine is provided. The relay device is integrally fixed to the mold. The relay device includes a storage configured to store specific information of the pressure sensor (S1 to Sn) provided to the mold to detect the inner pressure of the cavity (CT), the cavity (CT) being defined between a fixed-side mold and a movable-side mold of the mold.
Claims4
A relay device for a pressure detection device provided with a pressure sensor configured to detect an inner pressure of a cavity in a mold of an injection molding machine, the relay device being characterized in that
- the relay device is integrally fixed to the mold, and
- the relay device comprises a storage configured to store specific information of the pressure sensor provided to the mold to detect the inner pressure of the cavity, the cavity being defined between a fixed-side mold and a movable-side mold of the mold, wherein
- the specific information is a rated load of the pressure sensor and a pin-sectional area of an ejector pin to which the pressure sensor is attached.
A pressure detection device provided with a pressure sensor configured to detect an inner pressure of a cavity in a mold of an injection molding machine, the pressure detection device being characterized in that
- the pressure detection device comprises a relay device integrally fixed to the mold and configured to relay a sensor output from the pressure sensor to an external device, and
- the relay device comprises a storage configured to store specific information of the pressure sensor provided to the mold to detect the inner pressure of the cavity, the cavity being defined between a fixed-side mold and a movable-side mold of the mold, wherein
- the specific information is a rated load of the pressure sensor and a pin-sectional area of an ejector pin to which the pressure sensor is attached.
