It has analyzed the pulley injection formation craft and calculated the size of the mode lumen, elaborated the mold of pulley structural de
3、sign, elaborated how to determined the parting surface， the quantity of mode lumens ， the arrangement way, the casting system， the exhaust gas system, the sprinkle way， position of design, the structure of sprinkle parts, how to sprinkle the casting system congeal material ,the temperature control s
4、ystem ,the formation parts and the main structural design process. In the design, because the spare parts size is small and the accuracy request isnt high, in order to rise the rate of production, we adopted one mould and 8 mode lumens. In this paper, it has carried on the processing craft analysis of the major parts, and established the technological process card, through the mold design and the manufacture, the pulley injection formation has realized.
