Injection molding method and injection molding machine

The invention provides an injection molding method and an injection molding machine. In the present invention, mold clamping conditions including a predetermined mold gap (Lg), a predetermined mold clamping force (Pc), a predetermined back pressure (Pb) for a movable mold (Dm), a predetermined mold clamping pressure (Pp), and a predetermined mold clamping pressure adjustment condition (T) for a compressed state of a molding material (Rm) are set in advance. An injection-filling step (S7) in which a molding material (Rm) is injected and filled into a mold (D) of a mold closing device (Mc) for which mold closing conditions have been set by an injection device (Mi) is performed, and compression steps (S11-S15) are performed in accordance with mold closing conditions including a mold closing pressure adjustment condition (T) after the injection-filling step (S7) has ended. 本发明提供注射成型方法和注射成型机。预先设定包含规定的模具间隙(Lg)、规定的合模力(Pc)，针对可动模(Dm)的规定的背压(Pb)，规定的闭模压力(Pp)以及针对成型材料(Rm)的压缩状态的规定的闭模压力调整条件(T)的合模条件，在成型时，进行通过注射装置(Mi)向设定了合模条件的
