摘要： A die casting machine includes a stationary die half, an ejector holder block, and die core pieces that extend through the ejector holder block, defining a die cavity when closed. An ejector box backstops the closed ejector holder block and die core pieces. Melt is injected into the die cavity. After a first dwell time, the ejector box is retracted away from the ejector holder block while a closing force is simultaneously applied to maintain the ejector holder block closed on the stationary die half, and the die core pieces are retracted out of the die cavity. After a second dwell time, the melt completely freezes and the ejector block is separated from the stationary die half, opening the die cavity from which the resulting die cast block can be retrieved.

摘要： A liner for an extrusion press container comprises an elongate body having a longitudinally extending passage therein through which a billet is advanced, the passage having a generally rectangular cross-sectional profile. The liner further comprises at least one first longitudinally extending heating element accommodated by the body adjacent a first side of the passage, and at least one second longitudinally extending heating element accommodated by the body adjacent a second side of the passage. The first and second heating elements are individually controllable for controlling a thermal profile within the liner.

摘要： In a circular dummy block for use in an extrusion press for extruding through a die, extrudable metal, a bayonet type coupler for connecting the dummy block to a stem of the extrusion press. The bayonet type coupler comprises:i) a post having on its outer end portion a first set of lugs of the bayonet style coupler,ii) a recess in the stem and having about its periphery a second set of lugs complementary to the first set to complete the bayonet style coupler,iii) a connector for connecting an inner end portion of the post to the dummy block, the connector being adapted to permit longitudinal movement of the dummy block along the post toward the outer end portion and permit lateral movement of the dummy block relative to the post, such longitudinal and lateral movement of the dummy block relative to the post allowing the dummy block to float during use in an extrusion press, andiv) a lock device in the stem for fixing the post once the bayonet coupler is assembled by inserting the outer end portion in the recess to locate the first set of lugs inwardly of the second set of lugs and rotating the post to lock the first set of lugs behind the second set of lugs.
