Injection mold apparatus and method

摘要

An injection mold apparatus is configured with one or more secondary mold locks and matched shear parting lines to prevent relative movement of individual mold elements parallel to, and normal to a mold opening and closing axis. The secondary mold locks operate conjunction with a primary mold clamping unit to secure the injection mold in a closed configuration against movement parallel to a mold opening and closing axis. The matched shear parting lines are orientated at an angle relative to the mold opening and closing axis, defining contact surfaces which secure the injection mold elements against relative movement normal to the mold opening and closing axis.
