HEAT-INSULATION PADS FOR DIES Russian patent published in 2012 - IPC B21J13/03 B21D37/16 B30B15/34

Abstract RU 2455101 C1

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming, particularly, to isothermal moulding of magnesium and aluminium alloys. Heat-insulation pad arranged under die and die plate comprises metal sheets. Flexible interlayers are arranged between said sheets. Said sheets are made from metal with heat conductivity lower than 30 W/m·degree while interlayers feature heat conductivity lower than 1 W/m·degree. Pad base and top sheet feature thickness exceeding that of interlayers. Pad base and top sheet have grooves to receive thread bush and flanges aligned therewith. Top sheet is secured to base by said thread bushes and flanges that may displace axially.

EFFECT: decreased heat transfer from hot die to press components, hence, slower die cooling.
