Claims

[Scope of claim for utility model registration] Fixed side cavity plate, movable side core plate,
An injection compression molding mold having a movable runner plate that is supported to be movable by a predetermined amount in the axial direction relative to the movable core plate and forms a runner between the fixed side cavity plate and the fixed side cavity plate when the movable side core plate is in close contact with the fixed side core plate. a hydraulic seal fixed to the outer side of the cavity plate; a locking block attached to the piston rond of the hydraulic cylinder and having an inclined surface;
an inclined surface provided on the movable runner plate to correspond to the inclined surface of the locking block, and both inclined surfaces contact each other when the piston rod of the fluid pressure cylinder protrudes, and the movable runner plate A mold for injection compression molding, characterized in that the piston rond is pressed against a fixed side cavity plate, and is arranged so as to separate and release a movable side runner plate when the piston rond is retracted.
