摘要

PURPOSE:To provide an injection compression mold wherein injection compression molding with different lot can be performed by only exchanging a mold which is attachable to a general injecting machine. CONSTITUTION:A cut bush 10 being held movably at a movable mold 1 and its blade 10a is exposed to a cavity 20 and an inner bush 11 being held movably in the cut bush 10 and its end face 11a is exposed to the cavity 20 are arranged at the movable mold 1 in order to drive the bushes 10 and 11 in reverse direction of each longitudinal direction. A bush driving device 3 is provided for making the cut bush 10 advance to the cavity 20 dependent on a mold clamp PL2 of a shrunk quantity of resin so as to cut a gate and block the compressed quantity of resin in the cavity 20, and for making the inner bush 11 recede from the cavity 20 so as to absorb a quantity of resin of advanced quantity of the cut bush 10.
