A metal die casting machine having a safety bar mechanism for cushioning the stopping action of a movable platen when it is stopped prior to reaching the closed position of the dies. One embodiment provides a two-part bar connected together by a cushioning means. A second embodiment mounts a cushioning means on one of the platens, preferably the movable platen.

Die casting machine with safety bar

The shot cylinder mechanism is moved from a position for receiving molten metal to an injection position wherein the molten metal is injected into the die cavity of the die casting machine, and vice versa. The shot cylinder mechanism is swung in open space from one position to the other as it is guided by a linkage system having a geometry that takes advantage of the constant speed of the cylinder to give faster, non-linear motion in moving from one position to the next and then at the end of the injection position, the proper force is exerted on the shot cylinder mechanism to provide a seal between the shot sleeve and the opening leading to the die cavity.

A freestanding modular furniture arrangement is provided to create workstations in open office plans, and other similar applications. Each furniture unit includes a worksurface with capped cutouts in the rear corners to mount overhead cabinets, privacy screens, and other furniture accessories. A mounting rail extends continuously along the rearward edge of each worksurface, and is capable of removably supporting therein a plurality of different amenities, such as bookshelves, CRT stands, fans, task lamps, etc., so as to permit a worker to personalize his or her own workstation. A removable stanchion permits certain convertible amenities to be supported either freestanding on the worksurface, or along the rear of the worksurface on the mounting rail. An L-shaped intermediate leg is available to support the worksurface in a cantilevered fashion to facilitate unfettered task chair movement along the forward edge of the worksurface.
