CASTING MOLD FOR PRESSING EMBOSSING BUSHING WITH MULTIPLE PROTRUSION PATTERNS TO MANUFACTURE PRESSING EMBOSSING BUSHING INCLUDING OIL RESERVOIRS WITH VARIOUS INDENTED SHAPES BY PLASTICIZATION VIA METAL FLOW METHOD

摘要

According to the present invention, provided is a casting mold for a pressing embossing bushing. In manufacturing a sliding bearing having an inner circumference surface embossed in an indented shape by plasticization via a metal flow method; provided is a casting mold composed of steel bars with circular sections including a pressurizing part, and a protrusion part with a shape complementing the indented shape provided on an inner circumference surface of a round bar of a carbon steel constituting a main body of the sliding bearing, i.e., a casting mold for the pressing embossing bushing. A plurality of different protruding patterns are formed in an area partitioned into identical intervals on an outer circumference surface of the main body of the casting mold composed of bars with circular sections to enable continuous operation without the operation of replacing the casing mold with a casting mold; including protruding patterns with different shapes to plasticize various indented shapes in a circumferential direction on the inner circumference surface of the sliding bearing.;COPYRIGHT KIPO 2015
