Abstract: The moulding process of a carburetor was analyzed, and the design of the mould runner and gate, moulded parts, slider assembly, and thread demoulding mechanism were presented. It expounded design difficulties of the slider assembly and the thread demoulding mechanis. The mould debugging proved that the mould could product stably and operate simply.
Key words: carburetor; slider assembly; cooling system; thread demoulding mechanism; hot runner
