AI Technical Summary
Technical Problem
In injection compression molding, the mold opening size is prone to change during molding cycles or each molding process, leading to unstable molding and uneven molding quality.
Method used
A position sensor is installed in the injection molding machine to directly detect the mold opening amount. The mold closing device is controlled to keep the mold opening amount constant, thus ensuring the stability of the injection process.
Benefits of technology
By controlling the constant mold opening amount, injection stability is achieved in each molding cycle, ensuring the uniformity of molding quality.

Abstract
本发明提供使成形品的品质恒定的注射压缩成形方法、注射装置及注射成形机。在注射成形机(1)中，将直接检测模具(24、25)的开模量的位置传感器(36)设置于模具盘(7、8)或模具(24、25)。在实施由使模具(24、25)成为打开的状态并注射注射材料的开模注射工序和在开模注射工序之后驱动合模装置(2)而缩小模具(24、25)的开模量的压缩工序构成的注射压缩成形方法时，在开模注射工序中，以使由位置传感器(36)检测出的开模量恒定的方式控制合模装置(2)。由此，消除在开模注射工序中开模量因注射压力稍微扩大而注射不稳定的问题，成形品的品质稳定。
