摘要： A self-compensating support skate (46) for an annular hydraulic ram (15) mounted in the front stationary platen (10) of a “two-platen” injection molding machine (1) is disclosed. The hydraulic ram (15) fits into a central bore (22) in the stationary platen (10) and connects directly to a relatively thin die platen (11) that provides a mold mounting surface. The purpose of the skate (46) is to prevent movement (tilting) of the die platen (11) and the resulting misalignment with the movable platen (20) when the mold (30) is attached. The skate (46) is adjusted during assembly to compensate for the tolerance stack-up in the ram assembly. The “zero” clearance is maintained by disc springs (56) within the skate (46) that compensate for the expansions and contractions of the large diameter parts due to temperature variations. The die platen (11) is held in the aligned position by contact with the lower tie rods (7).

摘要翻译： 公开了一种用于安装在“双压板”注射成型机（1）的前固定压板（10）中的环形液压油缸（15）的自补偿支撑滑板（46）。 液压压头（15）装配在固定压板（10）中的中心孔（22）中，并且直接连接到提供模具安装表面的相对薄的压板（11）上。 滑板（46）的目的是防止模具台板（11）的移动（倾斜），以及当附接模具（30）时与可动压板（20）的不对准。 滑块（46）在组装期间进行调整，以补偿压头组件中的公差叠加。 “零”间隙由滑板（46）内的碟形弹簧（56）保持，其补偿由于温度变化引起的大直径部分的膨胀和收缩。 模具压板（11）通过与下拉杆（7）的接触而保持在对准位置。

摘要： Part ejection apparatus for ejecting molded parts from a mold carried by a movable platen in an injection molding machine. A plurality of linearly operating hydraulic cylinders are provided to move an ejector bar that is carried along guide rods supported by a movable platen so that the ejector bar moves toward and away from a mold member that is carried by the movable platen. Suitable connections can be provided between the ejector bar and the ejection mechanism of the mold to drive ejector pins carried by the mold for separating the molded part from the mold surface. Additionally, a rotary motor is also carried by the movable platen and has its axis coincident with the longitudinal axis of the movable platen for connection of an output shaft of the motor with a drive mechanism carried by a mold, the drive mechanism suitable for rotating rotatable cores that form internal threads on the molded article. The linear and rotary ejection apparatus can be used individually, or they can be used in appropriate sequence in a core-type mold where separation of the cores does not simultaneously effect separation of the part from the mold.

摘要： A movable platen structure for an injection molding machine in which the platen is in the form of a box-like structure that includes spaced front and rear plates. The platen structure includes a plurality of longitudinally extending beam members that interconnect the front and rear plates and are positioned in parallel relationship and in a generally rectangular array. The rear plate includes on its rear face a plurality of vertically extending pillow block members for pivotally carrying a pivot pin, the pillow block members having inclined sides that intersect with the rear face of the rear plate. Extending across the front face of the rear plate and opposite from the ends of the respective pillow blocks are an upper and a lower transverse beam member, each of which is formed integrally with the rear plate to provide additional structural stiffening and thereby permit the rear plate to be of a thinner and lighter structure.
