Patent ID: 7134637

Claim:
A gas purging block for use with injection molding and die casting systems, the block comprising: a first-side block having: a first-side inner surface; a first-side upper surface and a first-side lower surface; and a pair of first-side channels extending through the first-side block parallel to the first-side inner surface, wherein the channels are proximal the first-side inner surface such that cooling fluid is circulatable in the channels to facilitate heat transfer from the first-side inner surface; wherein the channels extend from the upper surface to the lower surface such that fasteners can be extended through the channels such that the first-side block can be mounted in a first configuration; such that the channels are adapted to selectively function as conduits for cooling fluid and as mounting bores for mounting the first-side block to a first holder block, and a second-side block having a second-side inner surface adapted to engage with the first-side inner surface to define a gas passageway.
