Abstract
In a mold clamping apparatus of an injection molding machine using five-point double toggles, a projection (17) is formed at a side of a link (14) of which one end is connected to a rear platen (6), that side being opposite to the side facing a crosshead (18). And a pin is inserted in a through hole formed in the projection (17) and a through hole formed in the other end of a link (16) of which one end is connected to the crosshead, with these through holes being in alignment with each other.
