Abstract

An injection-compression mold with variable compression strokes, which is composed of core side, cavity side, parting-line locking system, movable core system, and injection system. The innovation features are as follows: Split the conventional whole core to several sets of smaller movable cores, which can be covered by a covering sheet, if necessary, to form a core surface without splitting lines. The core stopping mechanism has different stopping heights, which are inverse proportional to their compression strokes. The mold will be pre-opened by a gap, which is the compression stroke for the later compression process. During the injection process, the cavity pressure will get higher and higher to push the movable cores back until they are stopped by the core stopping mechanism. After the injection process, the closing and clamping mold actions will drive the compression mechanism to push the movable cores to compress the plastic in the cavity. The movable cores have different compression strokes, which are designed from the different back amounts on them, so that they can move variable compression strokes onto the plastic in the cavity. This mold system, therefore, can overcome the uneven or over packing problem on the parts having variable thicknesses in conventional compression molding subjected to a constant compression stroke.
