Abstract:This article aimed to analyze the features of the cylinder and the mould of cylinder. An idea was pres鄄
ented that the mould of cylinder and the cylinder could be separated by the demoulding fixture. Through the analysis
of technical difficulties about the demoulding fixture and the possible emergence during demoulding, the process of the
design and the demoulding was introduced. It had been found that the structure of demoulding fixture was feasible. It
could meet the demoulding requirement of the mould .
