Die casting and like apparatus

Claim 1

In apparatus of the kind used for die casting, injection moulding and the like and which comprises: a. a body, b. first and second members mounted on the body for relative movement towards and away from each other, c. a plurality of elongate tie elements, each connected at one of its ends with said first member, and d. actuating means connected with the other end of each of said tie elements and connected also with said second member for urging one of said members towards the other, the arrangement being such that when the first and second members are subjected to compressive stress by operation of the actuating means, the tie elements are subjected to tensile stress, the improvement wherein: e. at least one of said first and second members is slidably mounted on said tie elements and is guided thereby, f. there is provided in association with each of said tie elements a respective chamber which, when the apparatus is in use, is filled with fluid, each of said chambers being interposed in the stress path to or through a respective one of said tie elements and comprising relatively movable wall portions for transmitting said stress through said fluid, and g. duct means interconnecting all of said chambers whereby the respective fluid pressures in the latter are equalised.
