    • 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 (3) is mounted so that a resin supplying hole of the cooling jacket communicates with a resin supplying hole of a heating cylinder (1). A sensor head (6) mounted on a sensor mounting plate (7) is inserted into the resin supplying hole (9) through a sensor insertion port (11) provided on a hopper plate (4) and a resin inlet (10) and detects the deposit level of the resin pellets (21) deposited in the resin supplying hole (9). Changing the extent of insertion of the sensor head (6) 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.
    • 本发明提供了能够以简单的结构调整检测水平并且检测塑化螺杆附近的树脂颗粒的沉积物水平的注射成型。 安装冷却套（3），使得冷却套的树脂供给孔与加热缸（1）的树脂供给孔连通。 安装在传感器安装板（7）上的传感器头（6）通过设置在漏斗板（4）和树脂入口（10）上的传感器插入口（11）插入到树脂供给孔（9）中，并且检测 沉积在树脂供应孔（9）中的树脂颗粒（21）的沉积层。 改变传感器头（6）插入的程度使树脂颗粒的沉积物检测水平发生变化，并且能够检测螺杆外周附近的沉积物水平。 设置与树脂沉积方向垂直的传感器检测方向，能够通过树脂颗粒使传感器检测表面弄脏而减少，从而能够减少错误的检测读数。
