Abstract

The invention provides an injection molding capable of adjusting a detection level with a simple structure and detecting a deposit level of the resin pellets near a plasticizing screw. A cooling jacket is mounted so that a resin supplying hole of the cooling jacket communicates with a resin supplying hole of a heating cylinder. A sensor head mounted on a sensor mounting plate is inserted into the resin supplying hole through a sensor insertion port provided on a hopper plate and a resin inlet and detects the deposit level of the resin pellets deposited in the resin supplying hole. Changing the extent of insertion of the sensor head enables the resin pellets deposit detection level to be changed, and further, enables the deposit level near the outer periphery of the screw to be detected. Setting the sensor detection direction perpendicular to the resin deposit direction enables dirtying of the sensor detection surface by the resin pellets to be reduced, thus enabling erroneous detection readings to be reduced.
