ABSTRACT:
The press is used for adjusting and testing mating die halves for use in die casting, injection molding and the like, of metals, metal alloys, and synthetic resin materials. The press includes a base formed by a pair of elongated, parallel and facing channels. Each channel has mounted therein, adjacent its lower flange, a respective elongated rigid horizontal guide, and adjustable wedges are provided for horizontally aligning each guide. One guide has a substantially rectangular cross-section and the other guide has a V-shape groove in its upper surface. A pair of fixed substantially planar vertical supports are fixedly mounted on the two channels at opposite ends thereof, and a third substantially planar vertical support is mounted on the two guides for movement toward and away from one of the fixed supports. The movable support and the one fixed support are formed for anchoring thereto of respective die halves of a mating pair. Three elongated axially fixed and non-rotatable screws extend between the two fixed vertical supports and through the movable support. The movable support has three rotatable nuts each threadedly engaged with a respective screw, and a chain drive or the like is provided for rotating the three nuts synchronously. One screw is located at one side of the movable support intermediate the height of the two fixed supports, and the other two screws extend through the movable support at the opposite side thereof, one substantially within the adjacent channel of the base and the other at the extreme upper end of the movable support. Thereby, an adequate space is provided for an operator to enter between the one fixed support and the movable support to mount and dismount the die halves and to adjust the latter.
