Abstract：In this work, it was to carry out research on the problems such as low service life and operation fault of the key spare parts of the 60m wheel fixed cast nickel machine. Analyses were conducted on the existing problems in the structure and material of the cast iron mould, the wheel and chain belt. The service life of a new nickel cast iron mold researched and produced to solve problems above is 5 times as old as original cast iron mold. The die structure of the casting nickel iron machine was also improved and the baffle plates were arranged on both sides of the injection die. As a result of the above measures, the service life of the wheel and chain operation was prolonged, the equipment running failure rate declined 80% and the annual economic benefit can be increased by 982 thousand yuan.
Key words：cast iron mold；wheel；chain belt
