In an injection compression-molding apparatus, a molded article is produced by
setting molds 10 and 11 to an intermediate clamped state, and then
by setting the molds 10 and 11 to a final clamped state by re-clamping
the molds 10 and 11 to each other after injecting melted resin into
a cavity defined by the molds 10 and 11. The apparatus includes a
clamping mechanism and a parallelism retaining mechanism 20. The clamping
mechanism has a mold-driving cylinder 7 for moving the movable mold 10
toward and away from the fixed mold 11, a guide engaging member 8,
support panels 4, 5, etc. so as to selectively set the molds 10 and
11 to the intermediate clamped state and the final clamped state. The parallelism
retaining mechanism 20 retains parallelism between the molds 10 and
11 in the intermediate clamped state by giving a corrective force to mold
attaching surfaces of the clamping mechanism where the respective molds 10
and 11 are mounted.
