    • An injection mold for producing, from thermoplastic plastic, fittings which have an annular groove on the inside. The injection mold includes an outer mold, divided into a first and second mold half and along a parting line, and a mold core being axially displaceable along a mold half. A complementary mold bead for forming the annular groove is formed by levers carrying ring segments. A slider, which bridges the parting plane of the outer mold and is connected to the second mold half, has guide grooves of differing obliqueness, in which there engage motionally lateral projections both of the mold core and of the actuating element. A guide, which extends the opening stroke of the mold core, is formed at a distance from the parting plane, between the slider and at least the mold core, the guide preferably comprising second, lateral projections and second guide grooves.
    • 一种用于从热塑性塑料制造在内侧具有环形凹槽的配件的注射模具。 注射模具包括分模为第一和第二半模并沿着分型线的外模,以及沿着半模轴向移动的模芯。 用于形成环形槽的互补的模圈由承载环段的杠杆形成。 桥接外模具的分型平面并连接到第二半模的滑块具有不同倾斜度的导向槽,其中模具芯和致动元件的动作横向突起接合。 延伸模芯的开口行程的导向件形成在离开分离平面的一定距离处,在滑块和至少模芯之间,引导件优选地包括第二横向凸起和第二引导槽。

    • A release mechanism operating to release molded articles from a third mold portion includes a guide coupled to the second mold portion forming a cam track. A cam follower coupled to the surfaces of the third mold portion, which are holding the molded articles, is engaged in the cam track when the second and third mold portions are within a pre-selected distance of each other. The cam follower interacts with the cam track to cause some initial movement of the surfaces holding the molded articles to a pre-release position for the holding surfaces so that the molded articles are loosely retained by the holding surfaces. A power operator, carried by the third mold portion and coupled to the article holding surfaces, is responsive to a signal to move the article holding surfaces from the pre-release position to a full release position when a molded article receiver is suitably positioned to receive the molded articles. The molded article receiver includes receiver tubes for receiving the molded articles. The receiver tubes have an open forward end configured to receive a molded article, a closed rearward end including a surface contact element movably situated with respect to the forward end. The surface contact element is configured to conform to a portion of the surface of the molded article. A vacuum duct couples the closed rearward end to a source of vacuum for assisting in the retention of the molded articles within the receiver tubes. An air cylinder is coupled to each surface contact element, and a pressure duct couples to each air cylinder to a source of air pressure for controlling the position of the surface contact element with respect to the forward end of the receiving tube.
    • 用于从第三模具部分释放模制品的释放机构包括联接到形成凸轮轨道的第二模具部分的引导件。 当第二和第三模具部分处于彼此预先选定的距离内时,联接到保持模制品的第三模具部分的表面的凸轮从动件接合在凸轮轨道中。 凸轮从动件与凸轮轨道相互作用,以使保持模制品的表面的一些初始移动保持在用于保持表面的预释放位置,使得模制品被保持表面松动地保持。 由第三模具部分承载并联接到物品保持表面的动力操作者响应于当模制物品接收器适当地定位以接收时将物品保持表面从预释放位置移动到完全释放位置的信号 模制品。 模制品接收器包括用于接收模制品的接收管。 接收器管具有构造成接收模制品的敞开的前端,封闭的后端包括相对于前端可移动地定位的表面接触元件。 表面接触元件构造成符合模制品的表面的一部分。 真空管道将封闭的后端连接到真空源,以帮助将模制品保持在接收管内。 气缸联接到每个表面接触元件,并且压力管道将每个气缸耦合到气压源,以控制表面接触元件相对于接收管的前端的位置。
