Abstract
An arrangement for securing a die to a die holder for use as a molding die in an injection molding machine permits the die to be oriented on the die holder in a number of different angularly rotated positions. Clamping bolts secured to the die extend perpendicularly of a contacting plane between the die and die holder and project into corresponding holes in the die holder. Slides are provided in passageways in the die holder with the passageways extending parallel to the contacting plane. The slides are displaceable in the passageways into securing and clamping engagement with the clamping bolts. The slides are wedge-shaped and inter-engage corresponding wedge-shaped recesses in the outer surface of the clamping bolts. The slides can be displaced by actuating members. Hydraulic piston cylinder units can be used as the actuating members for holding the slides in the clamped position during operation. The recesses in the clamping bolts are formed by circumferentially extending secant-like cuts in the outer surface of the bolts with the cuts having a wedge-shape corresponding to the wedge-shaped slides.
