WIPO Patent Application WO/2018/105227
Kind Code:
A1
Abstract:
Provided are a relay device configured to eliminate the need to calibrate an output value of a pressure sensor in a pressure detection device even when a mold is replaced, and a pressure detection device. A relay device (70) of a pressure detection device (100) provided with pressure sensors (S1 to Sn) that detect an internal pressure of a cavity (CT) in a mold (51) of an injection molding machine (1) is integrally fixed to the mold (51), and has a storage unit (71) in which unique information retained by the pressure sensors (S1 to Sn), provided in the mold (51) to detect the internal pressure of the cavity (CT) formed between a fixed mold (53) and a movable mold (58) of the mold (51), is stored.
