A Hot Runner Injection Mold for removing Undercut

摘要

A hot runner injection mold for processing an undercut is provided to prevent the interference of the outer core and slide core in rising the mold because the time difference pin is introduced by the outer core. A hot runner injection mold for processing an undercut comprises a fastened mold(1) and a moveable mold(2). The fastened mold comprises a resin injection unit(14), an angled block(15), and a slide core(16) which molds undercut of product. The angled block and slide core are coupled and interlocked to be slant. The resin injection unit is fixed so that it is not separated inside the fastened mold. After the injection molding is finished, the fastened mold rises with the resin injection unit and the angled block rises to be inclined in relation to the slide core and the slide core horizontally moves toward the direction which it can be separated from the undercut formed in product.
