摘要： A closure mechanism for a metallographic sample pressure molding system includes a mold cylinder having a bayonet socket for receiving a closure member which includes an upper ram mounted thereto for lockably enclosing the mold chamber defined by the cylinder. The closure member includes a cam and means for actuating the cam for moving the upper ram an incremental distance to break flashing from the molded metallographic specimen once cured for facilitating removal of the specimen and its surrounding thermoset or thermoplastic mount. In the preferred embodiment, the mold cylinder is demountable to a mold collar at an end remote from the closure member. A piston extends into the mold chamber through the collar and an alignment coupling joins the piston to a piston rod facilitating installation of the mold cylinder to the collar. The system provides a positive locking mold chamber with easy access and facilitates removal of the molded article by breaking the flashing from the article once molded.
摘要翻译：用于金相样品压力成型系统的闭合机构包括具有用于接收封闭构件的卡口式插座的模具圆筒，该闭合构件包括安装在其上的上压头，用于可锁定地封闭由气缸限定的模腔。封闭构件包括凸轮和用于致动凸轮的装置，用于使上部活塞移动一个增量的距离，以便一旦固化就能从模制的金相试样中闪烁，以便于移除试样及其周围的热固性或热塑性支架。在优选实施例中，模具圆筒可以在远离闭合构件的一端可拆卸到模具套环。活塞通过套环延伸到模具室中，并且对准联接件将活塞连接到活塞杆，从而有助于将模具缸安装到套环上。该系统提供了一种容易进入的正锁模模腔，并且通过一旦模制地破坏来自制品的闪光便于去除模制品。

摘要： A system for stepwise advancing a row of crucibles individually through a loading station of an induction furnace includes a plurality of articulated fingers for gripping each of the crucibles. The fingers are mounted to a first slide for movement along the direction of advancement of the crucibles. The first slide is mounted to a second slide for advancing and retracting the fingers into crucible engaging and disengaging positions, respectively. Control means are provided for controlling the movement of the slides and the articulated fingers sequentially to stepwise advance the crucibles through the loading station.
摘要翻译：用于逐步前进一排坩埚的系统通过感应炉的装载站分别包括多个用于夹持每个坩埚的铰接指状物。手指被安装到第一滑块上以沿着坩埚的前进方向移动。第一滑块安装到第二滑块，用于分别将手指前进和后退到坩埚接合和分离位置。提供控制装置，用于依次控制滑块和铰接手指的运动，以使坩埚逐步前进通过装载台。
