| 1. A mold clamping apparatus comprising:
a fixed platen fixed to a base,
a movable platen arranged, being opposed to said fixed platen, to be movable forward and backward,
a plurality of tie bars making said fixed platen and movable platen linkable to each other,
a mold clamping means causing a tensile force to act on said tie bars to clamp together a mold comprising a fixed mold fitted
to said fixed platen and a movable mold fitted to said movable platen and
a side pusher comprising a pair of supports respectively arranged between adjacent two tie bars out of said plurality of tie
bars at positions symmetrical to each other and slidably supported to said tie bars, a moving and positioning means linking
said supports to said fixed platen or movable platen and moving said supports to be positioned at a predetermined position
and a lateral clamping means provided on each of said pair of supports to push a side face of said fixed mold or movable mold.
