Abstract
The present invention relates to an injection molding machine having a novel key/slot arrangement for facilitating installation and removal of a central mold portion. The novel key/slot arrangement includes non-uniform width key elements on frame members which support the central mold portion and non-uniform width slots in side portions of the central mold portion for engaging the key elements. The machine further includes a novel rack/gear drive arrangement for insuring a proper positioning of the mold elements at all times.
