The utility model discloses a sensor soft glue mould of infrared sensor belongs to soft glue mould technical field. It aims at solving the problem of the existing infrared sensor soft glue mould's instability and the problem of the too fast exhaust of the initial stage of glue injection leading to the overflow of colloid. The mould includes oil base silica gel mould main part, is equipped with infrared sensor main part groove in the main part, sets up silica gel bubble at one end, and there is airbag in the bubble, and the main part groove is equipped with suction cup cavity near silica gel bubble and is connected with airbag through trachea, and annular magnet is installed in the groove of suction cup cavity side lower side; the outlet of top exhaust hole is equipped with elastic diaphragm, and the one end of diaphragm is connected with the exhaust hole inner wall joint groove cooperation, and the remote end has the gap. The mould is used for the infrared sensor metal surface casting silica gel soft film layer, can realize the double fixing of negative pressure and magnetic attraction, strengthens the stability, can also automatically adjust the exhaust speed according to the air pressure, avoids the overflow of colloid.
