摘要：
PROBLEM TO BE SOLVED: To obtain an accurately and a definitely metered amount of a resin by correcting a fluctuating amount of the metered resin resulted from an over run of a screw.
SOLUTION: A metering step is started and the screw revolves at a set rotating speed and backs under a back pressure controlling for keeping a resin pressure at a set pressure. The step is switched to a positioning control to a completion position of a set metering at a neighbor hood Ss of the set metering completion position of the screw, and a stopping command of the screw revolution is given. The screw is going to stop the revolution but by inertia of a motor and a screw driving mechanism or the like, the screw overruns by Aa and the screw revolution stops after the backing of the screw stops at a completion position of the set metering Sb. By reversely revolving the screw by a revolution of Ab corresponding to the over run Aa, the set metering amount of the resin corresponding to the overrun is corrected to obtain the amount of the resin of the set metering one. According to the above, a definite amount of the resin and an even weight of a molded article can be obtained.

要解决的问题：通过校正螺杆过度导致的计量树脂的波动量来获得准确和绝对计量的树脂。
解决方案：启动计量步骤，螺杆以设定的转速旋转，并在背压控制下回转，以保持树脂压力达到设定压力。 将该步骤切换到在螺杆的设定计量完成位置的相邻罩Ss处的设定计量的完成位置，并且给出螺杆转动的停止命令。 螺杆将停止旋转，但是通过电动机和螺杆驱动机构等的惯性，由Aa的螺杆溢出和螺杆转动在螺杆的背衬停止在设定的计量Sb的完成位置之后停止。 通过对与过运行Aa相对应的Ab的旋转来旋转螺杆，校正与超程相对应的树脂的设定计量量，以获得设定的计量树脂的量。 根据上述，可以获得一定量的树脂和均匀重量的模塑制品。 版权所有（C）2004，JPO
