摘要： An injection molding system is provided with a plurality of wall segments which are displaceable substantially radially for forming a substantially continuous wall which forms an internal wall of a hollow region which is intended to be filled with molten molding material. In a preferred embodiment, the wall segments are urged into sliding communication with one another and sealable engagement with a further wall portion by operation of an actuator assembly which is provided with canted pins which cause the wall segments to be moved radially inwardly and outwardly in response to orthogonal displacement of the actuator assembly. The invention is therefore particularly suited for forming molded articles having hollow interiors and/or internally ribbed portions. In an embodiment where a slot is desired in the molded article, a slot core is arranged to communicate with the molten molding material, so as to form the slot, and an ejection mechanism. During ejection, the slot core lifts the molded article out of the mold and is also extracted from the molded article during the ejection operation.
摘要翻译：注射成型系统设置有多个壁段，其可基本径向移动，以形成基本上连续的壁，该壁形成中空区域的内壁，该中空区域的内壁将被填充有熔融成型材料。在优选实施例中，壁段被推动成彼此滑动连通并且通过操作具有倾斜销的致动器组件与另一壁部分可密封地接合，致动器组件响应于径向向内和向外移动壁段到致动器组件的正交位移。因此，本发明特别适用于形成具有中空内部和/或内部肋状部分的模制品。在模制品中需要槽的实施例中，槽芯被布置成与熔融成型材料连通，以便形成槽和弹出机构。在排出期间，槽芯将模制品提出模具，并且在排出操作期间也从模制品中提取。

摘要： In a method and apparatus for casting or molding cages for rolling elements, two slides are provided for each pocket. The slides have an engaging, inclined surface, and are shaped to permit one of the slides to be removed by initially sliding it along the inclined surface. The other slide may thereby be moved laterally in the formed pocket, and withdrawn from the pocket. Facing slides of adjacent pockets may be joined together, with limited movement possible therein, to form a complete ring serving as a mold member.

摘要： A collapsible mold core comprises an inner core member, which remains out of contact with the inside peripheral surface of the molding, first and second pairs of mutually opposite, outer core members, which engage the molding and determine the shape thereof, and guides which converge toward the axis of the core and serve to guide the pairs of outer core members parallel to guide planes which are offset 90.degree. from each other and extend through the axis of the core. The four outer core members tightly adjoin each other, and the outer core members of the first pair have lateral wedge faces which extend parallel to the guides and at right angles to the guide plane of the outer core members of the second pair. The latter have inclined surfaces which are disposed on the side which faces the axis and are parallel to the wedge faces of the other outer core members, and the outer core members of both pairs are adapted to be displaced from a molding position in that longitudinal direction of the guides in which the latter converge. The displacement of the outer core members of the first pair is smaller than the displacement of the outer core members of the second pair.

摘要： A method for casting pneumatic tires by pouring a fluidized tire-forming material into a molding cavity defined between the outer peripheral surface of a separable hard core of a mold assembly and the inner peripheral surface of an outer separable hard mold member of the mold assembly. The separable hard core is composed of at least three segments and toroidal in shape. At least one segment of the separable core is retracted in a radial direction and then moved in a direction which does not hinder retractive movement of the remaining segments and subsequently these remaining segments are retracted in the radial direction, whereby the cast tire can easily be removed from the mold assembly.

摘要： An injection mold is disclosed for manufacture of a polygonal plastic article having plural side walls, a closed bottom wall and a constricted top opening. A mold core structure corresponds to the interior surface contour of the article in a mold defining position but is collapsible for withdrawal from the constricted top opening. The core includes a generally frusto-pyramidal central segment, and plural side wall and corner segments slidable along the inclined walls of the central segment. Preferred angular relationships of the corner and side wall segments and the slides of the central segment are also disclosed.

摘要： The decreased impact resistance of a unipartite plastic tub formed to include internal mold retention ribs is compensated for by the addition of external ribs, substantially coextensive in length and position with the internal ribs, having a width greater than that of the internal ribs to spread the stress concentration area beyond the juncture of the internal ribs and tub wall and thus avoid the conventional ''''notch'''' effect.

摘要： A core to be used for injection molding of or the forming of molded or extruded cylinders whereas they have threaded or otherwise undercut internal surfaces, in which the core die is collapsible enough to allow the molded or extruded part to be ejected from die. The walls of the core are not hinged but are formed from two sleeves which are slotted to form tines or springy segments, all of which are solidly paired together at one end. The segments are locked in place by means of a cam. The cam holds the segments so as to form an extremely solid die wall.
