A die-casting machine for the production of miniature die-cast parts of the type having a parting line and a plurality of cores includes a frame member having a plurality of tie bars and a first movable platen on one side of a parting line and a second movable platen on the opposite side of the parting line. The movable platens are slidably received by the tie bars and a pair of lever arms are provided wherein a first lever arm supports the first movable platen and a second lever arm supports the second movable platen. The die block is arranged into two halves about its own parting line such that one half is mounted to the first movable platen and the other half is mounted to the second movable platen. The particular arrangement of lever arms enables the die block to be positioned relative to the remainder of machine such that an arrangement of six retractable cores can be utilized as part of the die-cast part wherein there are three coaxial pairs configured for movement along conventional X, Y and Z axes. The positioning of the die block relative to the remainder of the machine is such that the total of six cores can be machine introduced without interference.
