DEVICE FOR PUNCHING FROM LIQUID METAL OF TAIL CUTTING TOOL ON DIE CASTING MACHINE WITH HORIZONTAL COMPRESSION BOX Russian patent published in 2009 - IPC B22D17/10 B22D18/02 

FIELD: metallurgy.

SUBSTANCE: invention can be used in devices for punching from liquid metal of cutting tool on die casting machines with horizontal compression box. Device contains compression box (1), press mold from mobile and immovable half-molds (10, 14), replaceable brasses (2, 3) with reach-through hole (5), additional brass (9) with salient recess (8) on butt and air duct (11) on its surface. Additional brass is implemented as stepless with reach-through air duct, connected in different sides with shape-generating salient recess and with air duct, communicating with vertical joint of press mold, and its outer diametre is equal to outer diametre of replaceable brasses and it is installed together with replaceable brasses with ability of blanking by travelling half-mold (10) and its change in compression box. Additional brass can be implemented in the form of cylindrical discs with projections and grooves, located in plane of vertical joint of discs diametrically from both sides of each of discs and providing its fixation to each other.

EFFECT: reduction of downtimes at changing of additional brasses and reduction of workload at processing of cutting tool.
