초록

An injection molding machine includes a stationary platen having a first mold half, at least one movable platen having a second mold half for forming a mold with the first mold half, tie bars for guiding the movable platen relative the stationary platen, and an injection unit for injecting molten resin into the mold. For at least one of the stationary and movable platen, a force is generated during clamping having a first direction. The at least one stationary and movable platens includes a first wall having edges and a central area and at least first an...
